Executive Summary
Background
The Indian River Lagoon (IRL) is a 156-mile-long estuary along Florida's east coast. The
impaired portions of the IRL are directly adjacent to lands in only Volusia, Brevard, Indian
River, and St. Lucie counties. The northern portion of the watershed extends to near the Ponce
De Leon Inlet in Volusia County and the southern portion to near the Fort Pierce Inlet at the
Indian River County —St. Lucie County boundary line. Because of the large geographical extent
of the IRL Basin and the hydrological differences throughout the basin, the Florida Department
of Environmental Protection (DEP) determined the best way to address the total maximum daily
loads (TMDLs) and impairments for the IRL Basin was to divide the watershed into 3 subbasins:
(1) Central IRL (CIRL), (2) North IRL (NIRL), and (3) Banana River Lagoon (BRL). Separate
basin management action plans (BMAPs) were developed for each subbasin; this document
focuses solely on the CIRL Subbasin. The main stem of the CIRL Subbasin extends from the
Melbourne Causeway in Brevard County to Fort Pierce Inlet, and includes the areas drained by
the Fort Pierce Farms Canal network and the C-25 Canal (Figure ES-1).
Intense and extensive algal blooms in the IRL began in 2011 and have returned periodically.
Harmful algal blooms (HABs) cause shading that stresses seagrass in the IRL, adverse effects on
wildlife, and in some cases, detrimental effects on human health. The St. Johns River Water
Management District (SJRWMD) launched the Indian River Lagoon Protection Initiative in
2013, including a multiyear investigation that increased the understanding of these blooms. This
and other research indicate it is important to persevere with projects that decrease nutrient loads
to the IRL, because that approach will limit the severity of HABs and their impacts on the
system.
TMDLs
A TMDL is a water quality restoration goal establishing the maximum amount of a pollutant that
a waterbody can assimilate without causing exceedances of water quality standards. The nutrient
TMDLs for the main stem of the IRL were adopted by DEP in March 2009. The TMDLs focus
on the water quality conditions necessary for seagrass regrowth at water depth limits where
seagrass historically grew in the lagoon, based on a multiyear composite of seagrass coverage.
The median depth limits of seagrass coverage in the IRL decreased over the years because of
changes in water quality conditions resulting from anthropogenic influences. As polluted runoff
reaches the lagoon, it contributes to conditions that prevent the seagrass from growing in deeper
water.
Additionally, TMDLs were adopted in 2013 for certain tributaries to the CIRL, now addressed in
this BMAP. For Crane Creek (waterbody identification [WBID] number 3085A), North Prong of
the Sebastian River (WBID 3128), South Prong St. Sebastian River Estuary Segment (WBIDs
3129B 1 and 3129B2), Sebastian River above Indian River (3129A), and the C-54 Canal (WBID
3135A), no further nutrient load reductions were requested beyond those already established for
the main stem seagrass nutrient TMDLs. For Goat Creek (WBID 3107A), the targets were also
Page 14 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
set to control nutrient loads from the watershed of the creek to restore seagrass distribution in the
IRL proper. No further nutrient reductions beyond those already being requested to protect the
main stem seagrasses were included in the Goat Creek TMDLs.
CIRL BMAP
In addition to dividing the overall IRL Watershed into subbasins, the CIRL was further divided
into "project zones." The project zone boundaries are based on the distinct hydrology in different
areas of the basin and their corresponding annual residence times. These zones are important
because the flushing times vary greatly among locations and consequently affect how nutrient
reductions will impact these distinct areas of the basin. The project zones identify large areas
where projects should be implemented to ensure that the load reductions achieve the desired
response for each subbasin. The CIRL Subbasin was split into four project zones, as follows:
• Central A — Melbourne Causeway (U.S. 192) to the north tip of Grant Farm
Island.
• Central SEB —Grant Farm Island to Wabasso Causeway (County Road 510).
• Central B — Wabasso Causeway to the boundary between Indian River County
and St. Lucie County.
• South IRL (SIRL) — The St. Lucie/Indian River County line to the Fort Pierce
Inlet.
TMDLs have not yet been developed for the SIRL; however, because of the connectivity of the
SIRL to the other three project zones, the reduction of loads here is critical for achieving the
TMDLs for the main stem of the IRL. The SIRL was therefore included in the CIRL BMAP
adopted in 2013, and load reductions were developed for the SIRL project zone as part of this
BMAP. Additionally, WBIDs 3163 and 3163B (C-25 canal) within the SIRL project zone are
impaired for nutrients, as indicated by elevated phosphorus levels and the abundance of
macrophytes.
DEP first adopted the CIRL BMAP in 2013 to implement total nitrogen (TN) and total
phosphorus (TP) TMDLs in three of the four CIRL Project Zones. BMAPs are designed to be
implemented in a phased approach. In 2018, DEP and several local stakeholders were developing
several components of an updated BMAP, including the local completion and DEP review of a
new water quality model, the Spatial Watershed Iterative Loading (SWIL) Model. The SWIL
Model was developed through cooperative funding provided by Brevard County, all of its cities,
and Florida Department of Transportation (FDOT) District 5, as well as support from the U.S.
Air Force, in an effort to update the data being used to predict loading. In this BMAP update, the
SWIL Model is used to estimate loading to the CIRL. The percent reductions adopted in the
original TMDL rules are applied as the water quality targets.
This 2020 BMAP was developed based on several changes since the 2013 BMAP was adopted,
including updated modeling efforts, boundary adjustments, updated allocations and load
Page 15 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
reductions to the responsible stakeholders, updated management actions to achieve nutrient
reductions, and a revised monitoring plan to continue to track trends in water quality. This
update sets a deadline for achieving load reductions no later than 2035, which is 22 years after
the initial BMAP adoption in 2013.
As part of the adaptive management process for this BMAP, DEP will explore refinements to the
SWIL Model used to develop BMAP allocations and estimate project credits. This effort could
include updates to some of the SWIL Model input layers (e.g., land use, soils, etc.), the
verification of watershed boundaries in some areas, revisions to the model period of record, and
the validation of predicted flows in selected calibration basins. There are also several optional
tasks that could streamline efforts during the load allocation and project calculation processes.
The SWIL Model revisions may change the loading estimates presented in this BMAP, and may
therefore result in changes to allocations in future iterations of the BMAP. Although the
direction and magnitude of those changes is uncertain, DEP anticipates that some may be higher,
and some may be lower.
Summary of Load Reductions
DEP requested stakeholders provide information on management actions, including projects,
programs, and activities, that may reduce nutrient loads to the CIRL. Management actions are
included in the BMAP to address nutrient loads to the lagoon and have to meet several criteria to
be considered eligible for credit. The estimated reductions of activities completed to date are
provided in Table ES-1. Figure ES- 2 and Figure ES- 3 show progress towards the TN and TP
TMDL load reductions through July 31, 2020.
To achieve the TMDLs, stakeholders must identify and submit additional local projects as well
as determine the significant funding that will be necessary. Enhancements to programs
addressing basinwide sources will also be required.

Florida law (Section 403.086, Florida Statutes [F.S.], and Chapter 2020-150, Laws of Florida)
requires all domestic wastewater facilities directly discharging to surface waters of the state
within or connected to the IRL to meet advanced wastewater treatment requirements no later
Page 16 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
than July 1, 2025. Additionally, this BMAP sets TN and TP effluent limits in the CIRL for
individually permitted domestic wastewater facilities and their associated rapid rate land
application (RRLA) effluent disposal systems and reuse activities, unless the owner or operator
can demonstrate reasonable assurance that the discharge or associated RRLA or reuse activity
would not cause or contribute to a failure to achieve the TMDLs or an exceedance of water
quality standards. Local governments must also develop remediation plans to address loads from
wastewater facilities and septic systems in the BMAP area.
Agricultural nonpoint sources are a significant contributor of TN and TP loading to the CIRL.
Since the adoption of the CIRL BMAP in 2013, some agricultural producers have enrolled in the
Florida Department of Agriculture and Consumer Services (FDACS) Best Management Practices
(BMP) Program. However, the current enrollment is 25 % of agricultural acres identified in the
BMAP. Sufficient agricultural BMP enrollment and implementation verification will be
necessary to achieve the TMDLs. FDACS continues to work to improve enrollment percentages
in the basin and will be undertaking implementation verification site visits to enrolled producers
at least every two years to carry out its statutory authority and fulfill its statutory obligations to
facilitate enrollment and implementation verification, pursuant to Paragraphs 403.067(7)(c) and
403.067(7)(d), F.S.
Within five years of the adoption of this BMAP, DEP will evaluate any entity located in the
BMAP area that serves a minimum resident population of at least 1,000 individuals who are not
currently covered by a municipal separate storm sewer system (MS4) permit and designate
eligible entities as regulated MS4s, in accordance with Chapter 62-624, Florida Administrative
Code (F.A.C.). In accordance with Subsection 373.4131(6), F.S., DEP and the water
management districts are planning to update the stormwater design and operation requirements in
Environmental Resource Permit rules and incorporate the most recent scientific information
available to improve nutrient reduction benefits.
Water Quality Monitoring
The updated CIRL BMAP monitoring network consists of 44 stations sampled by SJRWMD,
South Florida Water Management District, U.S. Geological Survey, Indian River Farms Water
Control District, Sebastian River Improvement District, Fort Pierce Farms Water Control
District, and North St. Lucie River Water Control District. The monitoring plan also includes
research priorities to better understand the lagoon, nutrient sources, and the responses of seagrass
to nutrient loading, both internal and external, to the lagoon.
BMAP Cost
The project costs provided for the BMAP may include capital costs as well as those associated
with construction, routine operations and maintenance, and monitoring. Many BMAP projects
were built to achieve multiple objectives, not just nutrient reductions. Funds for some projects
have already been spent, others have been obligated to ongoing projects, and the remainder are
yet to be appropriated.
Page 17 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
The funding sources for the projects range from local public and private contributions to state
and federal legislative appropriations. DEP will continue to work with stakeholders to explore
new opportunities for funding assistance to ensure that the activities listed in this BMAP can be
maintained at the necessary level of effort and that additional projects can be constructed by
2035.

Chapter 1. Background Information
1.1 Water Quality Standards and Total Maximum Daily Loads (TMDLs)
Florida's water quality standards are designed to ensure that surface waters fully support their
designated uses, such as drinking water, aquatic life, recreation, and agriculture. Currently, most
surface waters in Florida, including many of those in the Central Indian River Lagoon (CIRL),
are categorized as Class III waters, meaning they must be suitable for recreation and must
support fish consumption and the propagation and maintenance of a healthy, well-balanced
population of fish and wildlife. In addition, many waterbody segments (also known as waterbody
identification units, WBIDs) are categorized as Class II waters, which have a designated use of
shellfish propagation or harvesting. Table 1 lists all designated use classifications for Florida
surface waters.
Table 1. Designated use attainment categories for Florida surface waters
Class I, I -Treated, and II waters additionally include all Class III uses.

Class V Navigation, utility, and industrial use (no current Class V designations)
Class II waters in the CIRL may be used for aquaculture. The WBIDs that are designated as
Class II waters are listed in Table 2. If not listed, the remaining WBIDs are Class III waters.
Section 303(d) of the federal Clean Water Act (CWA) requires that each state must identify its
impaired waters every two years, including estuaries, lakes, rivers, and streams, that do not meet
their designated uses. Florida Department of Environmental Protection (DEP) staff in the
Division of Environmental Assessment and Restoration are responsible for assessing Florida's
waters for inclusion on the Verified List of Impaired Waters (when a causative pollutant for the
impairment has been identified) and Study List (when a causative pollutant for the impairment
has not been identified and additional study is needed). These lists are then provided to the U.S.
Environmental Protection Agency (EPA) as an update to the state's 303(d) list. In 2009, DEP
adopted, by Secretarial Order, revisions to the Verified List of Impaired Waters for the CIRL that
identified several estuarine segments as impaired for dissolved oxygen (DO) and nutrients. The
DO impairment was based on low DO concentrations measured in milligrams per liter (mg/L),
and the nutrient impairment was based on an imbalance in flora and fauna because of decreases
in seagrass distribution.

1.1.1. CIRL TMDLs
TMDLs are water quality restoration goals establishing the maximum amount of a pollutant that
a waterbody can assimilate without causing exceedances of water quality standards. The Indian
River Lagoon (IRL) TMDLs focus on the water quality conditions necessary for seagrass
regrowth at water depth limits where seagrass historically grew in the lagoon, based on a
multiyear composite of seagrass coverage. The median depth limits of seagrass coverage in the
IRL decreased over the years (see Section 4.2) because of changes in water quality conditions
resulting from anthropogenic influences.
As polluted runoff reaches the lagoon, it contributes to conditions that prevent the seagrass from
growing in deeper water because of elevated light attenuation. The full restoration depth -limit
target for seagrass was established for each segment based on a deep edge boundary delineating
the composite of 7 years of historical seagrass data for the period from 1943 to 1999. The
restoration targets were set at depths where the deep edge of the seagrass beds previously grew
and created a maximum depth limit for seagrass distribution. The TMDL targets allowed for a
10 % departure (shoreward) from the full restoration target seagrass depth. The 10 % departure
in target depths was selected to be consistent with the water quality criteria in Chapter 62-302,
Florida Administrative Code (F.A.C.), which allows for up to a 10 % reduction in the photo
compensation point.
To determine nutrient targets and reductions needed to improve lagoon water quality in each
subbasin, regression relationships were used between 4 years of loading levels and the same
years' seagrass depth limit (the percent departure from the full restoration). Total nitrogen (TN)
and total phosphorus (TP) targets were developed from the median concentrations observed
where seagrass depth limits were within the 10 % departure (shoreward) from their full
Page 23 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
restoration levels. These targets should result in nutrient reductions that allow seagrass to grow
almost to the depths previously seen in the area. Table 3 lists the TMDLs and pollutant load
allocations adopted by rule for the CIRL.

Additionally, this BMAP addresses adopted TMDLs for certain tributaries to the CIRL. For all
the CIRL tributaries, there are biochemical oxygen demand (BOD) TMDLs in rule. Also, for
these tributaries —Crane Creek (WBID 3085A), North Prong of the Sebastian River (WBID
3128), South Prong St. Sebastian River Estuary Segment (WBIDs 3129B1 and 3129132),
Sebastian River above Indian River (WBID 3129A), and C-54 Canal (WBID 3135A)no
further nutrient load reductions were requested beyond those already established for the main
stem seagrass nutrient TMDLs. For Goat Creek (WBID 3107A), the targets were also set to
control nutrient loads from the watershed of the creek to restore seagrass distribution in the IRL
proper. No further nutrient reductions beyond those already being requested to protect the main
stem seagrasses were included in the Goat Creek TMDLs.
Table 4 lists the tributary TMDLs in the CIRL.

1.2 CIRL Basin Management Action Plan (BMAP)
A BMAP is a framework for water quality restoration that contains local and state commitments
to reduce pollutant loading through current and future projects and strategies. BMAPs contain a
comprehensive set of solutions, such as permit limits on wastewater facilities, urban and
agricultural best management practices (BMPs), and conservation programs designed to achieve
pollutant reductions established by a TMDL. These broad -based plans are developed with local
stakeholders and rely on local input and commitment for development and successful
implementation. BMAPs are adopted by DEP Secretarial Order and are legally enforceable.
The Florida Watershed Restoration Act (FWRA), Subparagraph 403.067(7)(a)1., Florida Statutes
(F.S.), establishes an adaptive management process for BMAPs that continues until the TMDLs
are met. This approach allows for incrementally reducing loadings through the implementation
of projects and programs, while simultaneously monitoring and conducting studies to better
Page 25 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
understand water quality dynamics (sources and response variables) in each impaired waterbody.
The CIRL BMAP was first adopted in February 2013. An adaptive management process that is
statutorily required, such as the changes made in this updated BMAP, will continue until the
TMDLs are met.
This document serves as an update to the 2013 BMAP. Figure 1 shows the CIRL BMAP area.
Page 26 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
1.2.1. Pollutant Sources
There are various sources of pollution in the CIRL. Nonpoint (i.e., diffuse) sources in the
watershed contribute the majority of TN and TP loads to the CIRL and include urban and
agricultural runoff. For additional information on other sources not directly addressable through
anthropogenic activities, please refer to Section 1.2.4. The St. Lucie Estuary, to the south, is
being addressed through the St. Lucie River and Estuary BMAP.
1.2.1.1. Agricultural Noppoint Sources
The primary agricultural land uses in the CIRL BMAP area are grazing lands, fallow land, citrus,
and open lands. Other agricultural land uses include nurseries and horse farms/specialty farms.
Most of the horse farms are small, noncommercial hobby farms. Because of urban encroachment,
citrus health issues (freeze/disease), and the downturn in the economy, a majority of previously
existing citrus operations have been destroyed or abandoned, have significantly lowered their
production acreage, or have transitioned to another commodity. In recent years, some of this
acreage may have also shifted to nonagricultural/urban uses.
Per Section 403.067, F.S., when DEP adopts a BMAP that includes agriculture, it is the
agricultural landowner's responsibility either to implement BMPs adopted by Florida Department
of Agriculture and Consumer Services (FDACS) to help achieve load reductions, or to conduct
water quality monitoring pursuant to Chapter 62-307, F.A.C. Landowners that do not enroll in
the BMP program or conduct water quality monitoring are referred to DEP for enforcement
action. To date, the FDACS Office of Agricultural Water Policy (OAWP) has adopted BMP
manuals by rule for cow/calf, citrus, vegetable and agronomic crops, nurseries, equine, sod,
dairy, poultry, and specialty fruit and nut operations.
To enroll in the BMP Program, landowners first meet with OAWP to determine the BMPs that
are applicable to that individual operation. The landowner must then submit to OAWP a Notice
of Intent (NOI) to implement the BMPs on the checklist from the applicable BMP manual.
Because many agricultural operations are diverse and are engaged in the production of multiple
commodities, a landowner may be required to sign multiple NOIs for a single parcel.
OAWP is required to verify that landowners are properly implementing the BMPs identified in
their NOIs. Rule 5M-1.008, F.A.C., outlines the procedures used to verify the implementation of
agricultural BMPs. BMP implementation is verified through site visits conducted by OAWP staff
at least every two years, as required by Subparagraph 403.067(7)(d)3, F.S. Producers not
properly implementing BMPs according to the process outlined in Chapter 5M-1, F.A.C., are
referred to DEP for enforcement action after attempts at corrective and remedial action are
exhausted.
FDACS staff conduct site visits to verify that all BMPs are being properly implemented and to
review nutrient and irrigation management records. In addition, OAWP verifies that cost -share
items are being implemented correctly. Site visits are prioritized based on the date the NOI was
signed, the date of the last BMP verification site visit, and whether the operation has received
Page 28 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
cost -share funding. FDACS undertakes these onsite inspections at least every two years and
provides DEP with aggregated information on nutrient amounts being applied.
Where water quality problems are detected for agricultural nonpoint sources despite the
appropriate implementation of adopted BMPs, a reevaluation of the BMP manuals shall be
conducted pursuant to Subparagraph 403.067(7)(c)4., F.S.:
When water quality problems are demonstrated, despite the appropriate
implementation, operation, and maintenance of best management practices and
other measures required by rules adopted under this paragraph, the department, a
water management district, or the Department of Agriculture and Consumer
Services, in consultation with the department, shall institute a reevaluation of the
best management practice or other measure. If the reevaluation determines that
the best management practice or other measure requires modification, the
department, a water management district, or the Department of Agriculture and
Consumer Services, as appropriate, shall revise the rule to require implementation
of the modified practice within a reasonable time period as specified in the rule.
Where monitoring indicates that progress towards established BMAP goals is not being attained,
FDACS, DEP, and the water management districts may determine additional measures that can
be implemented to achieve the desired goals, including the reevaluation of BMPs and other
measures.. Additional information on the evaluation of BMPs is provided in Section 2.3.1.
Under Paragraph 403.067(7)(c), F.S., the proper implementation of FDACS-adopted, DEP-
verified BMPs, in accordance with FDACS rules, provides a presumption of compliance with
state water quality standards for the pollutants addressed by the BMPs. For the BMAP, the
implementation of agricultural BMPs will be documented based on participation in the FDACS
BMP Program. Table 5 and Table 6 summarize the agricultural land use enrolled in BMP
programs for the entire CIRL BMAP area and by project zone, respectively. Enrollment is as of
July 2020, and the agricultural acreage in each basin is based on the Florida Statewide
Agricultural Irrigation Demand (FSAID) VII Geodatabase. Appendix C provides more
information on agricultural activities in the CIRL BMAP area.

UNENROLLED AGRICULTURAL ACREAGE
Agricultural land use designation is not always indicative of current agricultural activity and
consequently presents challenges to estimating load allocations accurately as well as enrolling
every agricultural acre in an appropriate BMP manual. To characterize unenrolled agricultural
acres, OAWP identified FSAID VII features outside the BMP enrollment areas using geographic
information system (GIS) software (see Appendix C for details). Table 7 summarizes the results
of that analysis.
Table 7. Summary of unenrolled agricultural land use acreage in the CIRL BMAP area
Note: Because of geometric variations between shapefiles used in the unenrolled agricultural lands analysis performed by GAWP, the unenrolled
agricultural acres differ from subtraction of the FSAID VII Agricultural Acres in the BMAP and the Total Agricultural Acres Enrolled referenced
in Table 5.
Category Acres
Unenrolled agricultural acres 54,625
Acres identified within slivers of unenrolled agricultural areas 443
Lands without enrollable agricultural activity (e.g., tribal lands, residential
development, and parcels with Florida Department of Revenue (DOR) use 9,335
codes 70-98)
Total lands with potentially enrollable agricultural activities 44,847
As of July 2020, OAWP had enrolled 18,277 agricultural acres in BMPs. Considering the results
of the analysis shown in Table 7, the total acreage with the potential to have agricultural
activities that can be enrolled in the FDACS BMP Program in the watershed is 63,124 acres.
Using this adjusted agricultural acreage, 29 % of agricultural acres have been enrolled.
Analyzing land use data and parcel data is a valuable first step in identifying the agricultural
areas that provide the greatest net benefits to water resources for enrollment in FDACS' BMP
Program, as well as prioritizing implementation verification visits in a given basin. OAWP will
continue to enroll agricultural lands in the BMP Program, focusing on intensive operations,
including irrigated acreage, dairies and nurseries, parcels greater than 50 acres in size, and
agricultural parcels adjacent to waterways.
Page 30 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
The next step to help prioritize the enrollment efforts could use the parcel loading information
derived from the Spatial Watershed Iterative Loading (SWIL) Model. This effort could help
FDACS identify specific parcels with the highest modeled nutrient loading. These parcels could
then be targeted for the enrollment and implementation of BMPs, as well as the verification of
BMP implementation.
AQUACULTURE
Under the CWA, aquaculture activities are defined as a point source. Since 1992, all aquaculture
facilities have been regulated by DEP, the water management district, or both, through a general
fish farm permit authorized by Section 403.814, F.S. In 1999, the Florida Legislature amended
Chapter 597, F.S., Florida Aquaculture Policy Act, to create a program within FDACS requiring
Floridians who commercially culture aquatic species to annually acquire an Aquaculture
Certificate of Registration and implement Chapter 5L-3, F.A.C., Aquaculture BMPs. Permit
holders must reapply to be certified every year. However, as with agricultural land use in Florida,
aquaculture facilities are frequently in and out of production. The facilities for which acreages
were provided may no longer be in operation and there may be new companies in different parts
of the watershed. In the CIRL Subbasin, 306 acres of aquaculture are estimated to be under
certification with the FDACS Division of Aquaculture as of September 2020. For the purposes of
the BMAP, OAWP delineated the aquaculture facilities using parcel data. Since the acreages
were not delineated to just the tank, pond, or pool areas, in most cases these calculations
overestimate the acreages of aquaculture activity.
1.2.1.2. Municipal Separate Storm Sewer Systems (MS4s)
Many of the municipalities in the watershed are regulated by the Florida National Pollutant
Discharge Elimination System (NPDES) Stormwater Program. An MS4 is a conveyance or
system of conveyances, such as roads with stormwater systems, municipal streets, catch basins,
curbs, gutters, ditches, constructed channels, or storm drains.
If an MS4 permittee is identified as a contributor in the BMAP, the permitted MS4 must
undertake projects specified in the BMAP. The BMAP projects required to be undertaken by
MS4s are detailed for each project zone in Chapter 3. Phase I and Phase II MS4s are required to
implement stormwater management programs (SWMPs) to reduce pollutants to the maximum
extent practicable and address applicable TMDL allocations. Phase I MS4 permits include
assessment practices to determine the effectiveness of SWMPs, which can include water quality
monitoring. Both Phase I and Phase II MS4 permits include provisions for the modification of
SWMP activities, at the time of permit renewal, for consistency with the assumptions and
requirements of the adopted BMAP. There are no Phase I MS4 permittees in the CIRL as of
September 2020.
PHASE II MS4 STORMWATER PERMIT REQUIREMENTS
Table 8 lists the Phase II MS4s in the CIRL as of September 2020. Under a generic permit, the
operators of regulated Phase II MS4s must develop a SWMP that includes BMPs with
Page 31 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
measurable goals and a schedule for implementation to meet the following six minimum control
measures:
• Public Education and Outreach — Implement a public education program to
distribute educational materials to the community or conduct equivalent
outreach activities about the impacts of stormwater discharges on waterbodies
and the steps that the public can take to reduce pollutants in stormwater
runoff.
• Public Participation/Involvement — Implement a public
participation/involvement program that complies with state and local public
notice requirements.
• Illicit Discharge Detection and Elimination — Subsection 62-624.200(2),
F.A.C., defines an illicit discharge as "...any discharge to an MS4 that is not
composed entirely of stormwater...," except discharges under an NPDES
permit, or those listed in rule that do not cause a violation of water quality
standards. Illicit discharges can include septic/sanitary sewer discharge, car
wash wastewater, laundry wastewater, the improper disposal of auto and
household toxics, and spills from roadway accidents.
o Develop, if not already completed, a storm sewer system map showing
the location of all outfalls, and the names and location of all surface
waters of the state that receive discharges from those outfalls.
o To the extent allowable under state or local law, effectively prohibit,
through ordinance or other regulatory mechanism, nonstormwater
discharges into the storm sewer system and implement appropriate
enforcement procedures and actions.
o Develop and implement a plan to detect and address nonstormwater
discharges, including illegal dumping, to the storm sewer system.
o Inform public employees, businesses, and the general public of hazards
associated with illegal discharges and improper waste disposal.
• Construction Site Runoff Control —
o Implement a regulatory mechanism to require erosion and sediment
controls, as well as sanctions to ensure compliance, to reduce pollutants
in any stormwater runoff to the Phase II MS4 from construction activity
that results in a land disturbance greater than or equal to an acre.
Construction activity disturbing less than one acre must also be
included if that construction activity is part of a larger common plan of
development or sale that would disturb one acre or more.
Page 32 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
o Develop and implement requirements for construction site operators to
implement appropriate erosion and sediment control BMPs.
o Implement requirements for construction site operators to control waste
such as discarded building materials, concrete truck washout,
chemicals, litter, and sanitary waste at the construction site that may
cause adverse impacts to water quality.
o Develop and implement procedures for site plan review that incorporate
the consideration of potential water quality impacts.
o Develop and implement procedures for receiving and considering
information submitted by the public.
o Develop and implement procedures for site inspection and the
enforcement of control measures.
• Postconstruction Runoff Control — Implement and enforce a program to
address the discharges of postconstruction stormwater runoff from areas with
new development and redevelopment. (Note: In Florida, Environmental
Resource Permits issued by water management districts typically serve as a
Qualifying Alternative Program for purposes of this minimum control
measure.)
• Pollution Prevention/Good Housekeeping — Implement an operations and
maintenance (O&M) program that has the ultimate goal of preventing or
reducing pollutant runoff from MS4 operator activities, such as park and open
space maintenance, fleet and building maintenance, new construction and land
disturbances, stormwater system maintenance, and staff training in pollution
prevention.
The "NPDES Generic Permit for Discharge of Stormwater from Phase II MS4s," Paragraph 62-
621.300(7)(a), F.A.C., also requires that if the permittee discharges stormwater to a waterbody
with an adopted TMDL pursuant to Chapter 62-304, F.A.C., then the permittee must revise its
SWMP to address the assigned wasteload in the TMDL. Additionally, in accordance with
Section 403.067, F.S., if an MS4 permittee is identified in an area with an adopted BMAP or a
BMAP in development, the permittee must comply with the adopted provisions of the BMAP
that specify activities to be undertaken by the permittee.
DEP can designate an entity as a regulated Phase II MS4 if its discharges meet the requirements
of the rule and are determined to be a significant contributor of pollutants to surface waters of the
state in accordance with Rule 62-624.800, F.A.C. A Phase II MS4 can be designated for
regulation when a TMDL has been adopted for a waterbody or segment into which the MS4
discharges the pollutant(s) of concern. If an MS4 is designated as a regulated Phase II MS4, it is
Page 33 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
subject to the conditions of the "NPDES Generic Permit for Stormwater Discharges from Phase
II MS4s."

1.2.2. Milestones and Tracking Progress
The projects and activities in the BMAP are key to the overall goal of recovering seagrass in the
lagoon. The estimated benefits of these implemented activities are tracked to show stakeholder
efforts by determining a percentage towards the total required reductions to be achieved at each
milestone. Additionally, stakeholders provide DEP with reasonable assurance that they have a
plan to achieve the individually assigned reductions required in Chapter 2. Subparagraph
403.067(7)(a)6., F.S., indicates that an assessment of progress towards the BMAP milestones
shall be conducted every five years, and plan revisions made as appropriate. To meet these
requirements, DEP has established milestones for the years 2025, 2030, and 2035. The percent
reductions in the milestones apply to the total BMAP required reductions, so as various entities
implement their projects, the overall milestones are also being met.
The following percent reduction goals are proposed for each milestone and may be adjusted as
the BMAP is adaptively managed through future phases:
• 5-year milestone in 2025: 35 % or 320,614 lbs/yr of TN and 77,290 lbs/yr of
TP. Based on model revisions, reset 10-year and 15-year milestones, as
needed.
• 10-year milestone in 2030: 70 % or 641,228 lbs/yr of TN and 154,580 lbs/yr
of TP.
• 15-year milestone in 2035: 100 % or 916,040 lbs/yr of TN and 220,828 lbs/yr
of TP.
By the next milestone in 2025, at least 35 % of the TN and TP required reductions must be met.
Figure ES- 2 and Figure ES- 3 show the milestones as well as the cumulative TN and TP
reductions over time as projects are completed in each reporting period. The deadline established
by this BMAP for achieving the full load reductions is 2035, which is 22 years after the initial
adoption of the 2013 BMAP.
1.2.3. Assumptions
The water quality impacts of BMAP implementation are based on several fundamental
assumptions about the pollutants targeted by the TMDLs, modeling approaches, waterbody
response, and natural processes. The following assumptions were used during the BMAP
process:
• Certain BMPs were assigned provisional nutrient reduction benefits for load
reductions in this BMAP iteration while additional monitoring and research
are conducted to quantify their effectiveness. These estimated reductions may
change in future BMAP iterations as additional information becomes
available.
Page 39 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
• The nutrient reduction benefits of the stakeholders' projects were calculated
using the best available methodologies. Project -specific monitoring, where
available, will be used to verify calculations, and reduction benefits may be
adjusted as necessary.
• The TMDLs require TN and TP reductions from the watershed to improve
water quality in the CIRL to allow seagrass to grow at greater water depths.
High watershed nutrient loadings result in high chlorophyll a concentrations
in the lagoon, which may indicate algal growth and a reduction in light
availability to the seagrass, thus limiting the depth at which seagrass can
grow. Therefore, reducing nutrient loading to the CIRL is an important factor
in improving seagrass depth limits.
• The allocations do not require load reductions from areas identified as natural
land use areas in the modeled land use/land cover information. These loads
are considered uncontrollable, background sources, and the stakeholders are
not required to make reductions on natural lands. The BMAP allocations focus
on urban and agricultural stormwater sources and septic systems in the
watershed.
• Water is exchanged between the CIRL and other nearby waterbodies (the
North Indian River Lagoon [NIRL], Banana River Lagoon [BRL], and St.
Lucie River and Estuary), and water quality conditions in the CIRL may be
influenced by conditions in nearby waters. To help address these nearby
conditions, separate BMAPs have been adopted for these watersheds.
1.2.4. Considerations
This BMAP requires stakeholders to implement their projects to achieve reductions within the
specified period. However, the full implementation of this BMAP will be a long-term, adaptively
managed process. While some of the BMAP projects and activities were recently completed or
are currently ongoing, several projects require more time to design, secure funding, and
construct. Regular followup and continued coordination and communication by the stakeholders
will be essential to ensure the implementation of management strategies and assessment of
incremental effects.
During the BMAP process, a number of items were identified that should be addressed in future
watershed management cycles to ensure that future BMAPs use the most accurate information:
• Harmful Algal Blooms (HABs) — HABs cause shading that stresses seagrass
in the IRL, adverse effects on wildlife, and in some cases, detrimental effects
on human health. Intense and extensive algal blooms in the IRL began in 2011
and have returned periodically, with clear impacts on the extent, density, and
depth where seagrasses grow; some fish kills; and, fortunately, little direct
impact on human health. Compared with earlier blooms, the recent blooms
Page 40 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
have been dominated by smaller species of algae called nanoplankton and
picoplankton. SJRWMD launched the Indian River Lagoon Protection
Initiative in 2013, including a multiyear investigation that increased the
understanding of the blooms. This and other research indicate it is important
to persevere with projects that decrease TN and TP loads to the IRL, because
that approach will limit the severity of HABs and their impacts on the system.
• Land Uses — The loading estimates in the BMAP are based on land uses at a
point in time, allowing the model to be calibrated. The loading estimates for
this BMAP iteration were based on land use/land cover data from
approximately 2015 from the water management districts as well as property
appraiser data. Land uses in the model will be updated during future model
revisions based on the most recent and accurate data available; this may result
in changes to loading estimates.
• Basin Boundaries — Figure 4 shows the previous and updated BMAP
boundary. Overall, 1,214 acres were added to the BMAP area and 122,538
acres removed, resulting in a net reduction of 121,144 acres. When the 2013
basin boundary was developed, there was uncertainty about whether some
areas drained to the IRL, to the Upper St. Johns River, or to other adjacent
waterbodies. The boundaries were adjusted based on the best information
available about the hydrology of the IRL, but future adjustments may be made
because of flow diversions or updated information.
• Jurisdictional Boundaries — Entities may experience shifts in their
jurisdictional boundaries over time that require allocation adjustments.
Changes to the boundaries and/or allocations for these stakeholders may be
made as necessary and reflected in future BMAP iterations.
• SWIL Model — The SWIL Model was initially developed through cooperative
funding provided by Brevard County, all of its cities, and FDOT District 5, as
well as support from the U.S. Air Force, for purposes other than the BMAPs,
and DEP will explore refinements that may help improve the future use of the
SWIL for the IRL BMAPs. This effort could include updates to some of the
SWIL Model input layers, the verification of watershed boundaries in some
areas, revisions to the model period of record, and the validation of predicted
flows in selected calibration basins. There are also several optional tasks that
could streamline efforts during the load allocation and project calculation
processes. DEP expects the SWIL Model enhancements to change the loading
estimates and the CIRL future allocations. Although the direction and
magnitude of those changes are not certain, DEP anticipates that some may be
higher, and some may be lower.
• Community Development District (CDD) Responsibilities —DEP has had
several communications with the CDDs located in the CIRL. CDDs were
Page 41 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
assigned allocations only if three criteria were met: (1) there is development
i.e., roads and infrastructure —in the CDD area; (2) the CDD does not
discharge to an MS4; and (3) the CDD pays a stormwater fee and receives a
refund of this fee. CDDs that did not receive an allocation in this BMAP
iteration may receive allocations in future BMAP iterations.
• Special Districts — Water control districts (WCDs) and similar types of
special districts have been assigned qualitative allocations for the canals and
rights -of -way to the special districts, as the districts have control over these
portions of their jurisdictions. These districts are required to implement
specific canal and right-of-way BMPs to be compliant with the BMAP. The
BMPs for each special district are based on the activities and land uses within
the district, and reporting on those BMPs is due annually. The specific
approach for each special district is described in Appendix E, and will be
reevaluated in each 5-year BMAP update. The evaluation will be based on the
special district's operations, authorities, and utilization of those authorities.
• Complexity of the Problem — DEP acknowledges the complexity of the
dynamics affecting the water quality of the CIRL; therefore, this BMAP is
designed to encompass a wide variety of projects and management strategies
that will cumulatively act to significantly reduce nutrient loads. In estuarine -
based systems, the interaction with ocean waters and freshwater inflows adds
variability to the water quality conditions —including those associated with
climate change and sea level rise. Other factors such as inconsistency in
annual rainfall amounts, changing land uses and farming practices, and
internal nutrient sources such as muck deposits also complicate measuring the
benefits of projects and management strategies and understanding the
relationship between nutrient loading and the biological response of the
seagrass deep edge.
• Sea Level Rise — Sea level rise and changes in lagoon water depth over time
affect the depth at which seagrass growth is measured for TMDL compliance
and for assessing seagrass restoration. Improved depth estimates and seagrass
deep edge assessment techniques are needed.
• Previous Restoration Efforts — DEP recognizes that stakeholders throughout
the watershed have implemented stormwater management projects prior to the
implementation of the TMDLs and that these efforts have benefited water
quality. Projects completed in 2000 or later are considered for credits and
inclusion in the BMAP.
• Atmospheric Deposition — Reductions in atmospheric deposition have
occurred over time and are expected to continue. This BMAP and all
subsequent nutrient reduction requirements and allowable loads factor only
those inputs directly from the watershed. DEP will continue to monitor
Page 42 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
atmospheric deposition and may address it in future BMAP iterations as part
of the adapative management process.
• Muck Deposition — Muck deposits contain nutrients that flux into the water
column, increasing the abundance of phytoplankton, drift macroalgae, and
epiphytes that attenuate light and constrain seagrass growth and propagation.
Most IRL muck originates from upland soils and vegetation. For this reason,
stringent watershed soil -erosion control and soil/vegetation containment
measures are needed. Without such measures in place, muck removal will
need to be frequently repeated, which is neither cost-effective nor time
efficient. Ideally, muck removal projects should be performed in conjunction
with soil and vegetation retention programs, including public awareness
activities, that limit the amount of muck material deposited into the IRL. The
SWIL Model does not automatically take this process into account; however,
guidance documentation has been developed for crediting muck removal
projects specifically from the lagoon.
• Tributary Water Quality Impairments — DEP has identified tributary
nutrient impairments within the SIRL project zone but has not yet set water
quality targets with TMDLs. Specifically, WBIDs 3163 and 3163B (C-25
canal) are impaired for nutrients, as indicated by elevated phosphorus levels
and the abundance of macrophytes.

1.3 Economic Benefits of the IRL System
The IRL is a valuable ecological and economic asset for the state of Florida and the counties that
border the lagoon and its tributaries. It is considered one of the most biologically diverse
estuaries in North America and was recognized as part of the National Estuary Program (NEP) in
1990. The lagoon directly and indirectly supports a large part of the region's and the state's
economy. The basin supports the multimillion -dollar Indian River citrus industry and boat and
marine sales industries. Finfish and shellfish harvesting from the lagoon also contribute to local
economies.
An economic study prepared by the East Coast Florida Regional Planning Council (ECFRPC)
and Treasure Coast Regional Planning Council (TCRPC) (ECFRPC and TCRPC 2016) estimated
the total annual value of the lagoon's benefits at $7.6 billion, measured in 2014 dollars. This does
not include the estimated $934 million in annualized real estate value added for property located
on or near the IRL (Hazen and Sawyer 2008). The study area spanned from Ponce de Leon Inlet
in Volusia County to the Jupiter Inlet in Palm Beach County, and included all of Brevard, Indian
River, St. Lucie, and Martin Counties. The economic analysis was primarily conducted using the
Impact Analysis for Planning (IMPLAN) Regional Economic Input/Output Model, which
estimates direct, indirect, and induced economic effects, as outlined in Figure 5.
Page 45 of 202

The primary IRL-related industry groups identified in the study are Living Resources, Marine
Industries, Recreation and Visitor -Related, Resource Management, and Defense and Aerospace.
The breakdown of the monetary contribution to the IRL regional economy is shown in Figure 6.

Money spent on recreation and visitor -related activities generated $1.57 billion of economic
benefit. In 2014, over 7.4 million visitors traveled to the IRL region. Between 2.3 and 3.5 million
visitors to the IRL region participate in IRL-related recreation, and each visitor spends an
average of $162 a day. By 2025, the IRL region is anticipated to receive over 11 million visitors
annually.
The study also estimated the cost of a sustainable IRL-based economy and return on investment
for achieving water quality and seagrass restoration goals for the IRL. The annualized cost of
achieving the nutrient load reductions required by the four BMAPs that span the entire area was
estimated at $230 million. When compared with the $7.6 billion valuation of the region's average
annual economic output, the return on investment from achieving water quality and seagrass
restoration goals is 33 to 1. Therefore, investing in projects and programs to improve the lagoon's
water quality and seagrass beds is not only important for environmental considerations but also
to improve the regional economy.
Page 47 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
Chapter 2. Modeling, Load Estimates, and Restoration Approach
2.1 BMAP Modeling
Nutrient loading estimates were originally calculated for the BMAP using the Pollutant Load
Screening Model (PLSM) which was expanded by SJRWMD to represent year 2000 loading
(Adkins et al. 2004) in most of the IRL Watershed (excluding the IRL south of the Indian River —
St. Lucie County boundary). The seagrass depth limits were developed by SJRWMD based on a
series of photo -interpreted seagrass coverages from 1943 through 2001. DEP reviewed these
models and the seagrass depth limits and used them to develop the IRL TMDLs that were
adopted by rule (Gao 2009).
Through cooperative local effects, all the MS4 permittees within the Brevard County section of
the IRL (17 entities) partnered to fund a Study Team to create a new watershed model that would
update and refine the information that was used in the PLSM and associated TMDLs for the IRL.
One outcome of this study was the development of the SWIL Model, which is intended to
incorporate more available data, more recent conditions, and more temporally fine datasets.
SWIL is a custom ESRI ArcGIS toolset, originally designed to provide a continuous monthly
simulation of runoff over a 16-year period (Applied Ecology 2019).
During 2017 and 2018, while DEP prepared to calculate allocations for the CIRL BMAP, the
SWIL Model was proposed as an alternative to the previously used PLSM. Several options were
presented for updating allocations during a public meeting in May 2017, and the options were
discussed by DEP and stakeholders during and after the meeting. In November 2017, a
presentation was made to the IRL NEP Science, Technology, Engineering, and Mathematics
(STEM) Committee to provide a technical overview of the SWIL. During the annual public
meeting for the IRL BMAPs in December 2018, a proposed path forward was presented that
included applying the SWIL to calculate allocations for the IRL BMAPs. A technical
presentation was given by the model developer at a public webinar in January 2019 to provide
stakeholders with an opportunity to discuss the model further. Finally, during the annual public
meeting for the IRL BMAPs in December 2019, a summary of the allocation approach using
SWIL was presented.
2.1.1. SWIL Modeling
The initial version of SWIL was developed for the IRL in 2012 (SWIL 1.0). To address several
DEP comments and to improve execution and processing time, SWIL 2.0 was released in July
2014. SWIL 3.0 was released in April 2015 with improved model calibration to the measured
available gauge data, including a revised method to derive baseflow volumes and loads. SWIL
3.0 also incorporated new evapotranspiration raster datasets. SWIL 4.0 was developed in support
of the 3D numerical modeling effort led by the Florida Institute of Technology. Three major
changes were performed for SWIL 4.0: (1) Expansion of the model extent to provide nutrient
loadings from Ponce Inlet to Fort Pierce; (2) temporal expansion to include 2011 to 2015, for a
Page 48 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
total model period of 20 years (1995 to 2015); and (3) the addition of a third land use/treatment
time step using data from 2015 (Applied Ecology 2019).
2.1.2. SWIL Calibration
The SWIL 3.0 version was used for calibration using flow data primarily from the CIRL. The
five gauged stations included in the calibration are located in the following basins: Crane Creek,
Hickory Creek, North and South prongs of the Sebastian River, and Fellsmere Canal. Few data
were available in the NIRL and none in the BRL, and so the calibration is based primarily on the
CIRL conditions. Also, during the calibration process, a change was made to the normalization
process of the baseflow volumes by incorporating "groundwater storage depth," an area -
weighted groundwater input variable (Applied Ecology 2015). The calibration was based on
simulated 1995-2010 flow volumes compared against measured data at the gauged stations.
Since the treatment layer inputs to the model simulation did not incorporate BMPs beyond
permit requirements after the year 2000, most projects installed from 2000 onward were not
included in the calibration and are not well represented in the SWIL Model loading estimates.
Therefore, projects completed from 2000 onward are eligible for BMAP credit.
2.1.3. Allocation Process
To generate average annual TN and TP loads from the IRL Watershed, SWIL was run using
rainfall inputs that were thought to be from a representative period covering various conditions
from high to low rainfall years. The outputs from this model run were used to generate a GIS-
based Load Estimation Tool (LET) that included annual average loads from the watershed and
was the basis of the allocation calculations.
The LET based on the SWIL Model can produce polygon outputs with loading data included.
The determination of each entity's loading was performed using the LET and a GIS process.
Through a series of GIS steps, polygons were generated for each stakeholder. GIS data were
used to clip the area within the BMAP boundary associated with each entity's jurisdictional
boundary or the codes from the model land cover data related to natural and agricultural lands.
The clipping process was done sequentially, as follows:
1. Dispersed Water Management (DWM) or Comprehensive Everglades
Restoration Plan (CERP) projects.
2. Roads (FDOT and Florida's Turnpike Enterprise).
3. WCDs and improvement district canals and rights -of -way.
4. Natural lands (land use codes 3000 [not including 3300], 4000, 5000, and
6000).
5. Agriculture (land use codes 2000 and 3300).
6. CDDs, if they meet the criteria.
7. Municipalities.
Page 49 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
8. Remaining area assigned to each county.
Loads within DWM or CERP project areas were not included in the total loads for the project
zone, since these land uses are being converted to treatment projects. Loads from natural land
uses were not assigned to any specific entity's starting load. FDOT, agriculture, CDDs,
municipalities, and counties were assigned starting loads based on this sequential process. The
WCDs and Sebastian River Improvement District were assigned a qualitative allocation and are
required to implement specific BMPs, as discussed in Appendix E.
2.1.4. Project Credit Process
The LET was used to calculate updated TN and TP baseloads from all existing project treatment
areas in the BMAP. The August 2020 DEP BMP Efficiencies Guidance document was used to
determine the appropriate credit calculations for the various project types. Some project types
that have credits based on measured data or weighed material, such as street sweeping, did not
need to be updated using the LET.
2.2 Calculation of Starting Loads and Allocations
This section describes the process used to calculate the load reductions needed to achieve the
TMDLs and to allocate the load reduction requirements to the responsible stakeholders.
2.2.1. Starting Loads and Allocation of Load Reductions
DEP requested to use the SWIL 4.0 Model to update the load allocations for the second cycle of
the IRL BMAPs. To develop the loads that represent updated current conditions, the SWIL
Model was customized for this use with the following parameters (Applied Ecology 2018):
• A 50 x 50-meter (m) cell size was used, which is a much higher spatial
resolution than any previously developed watershed loading models for the
IRL.
• Land use corresponds to 2015 conditions and is derived from water
management districts land use data, property appraiser data, and local
government natural communities land cover, where available.
• Treatment layer (stormwater BMPs) corresponds to development conditions in
approximately 2015, excluding any retrofits implemented by the stakeholders
in the IRL Watershed. Retrofit projects will need to be retroactively calculated
and provided as credits to the stakeholders.
• Period -of -record rainfall that includes 2004 to 2017 data, which allows for a
wide range of rainfall conditions to represent the variability in loading to the
IRL.

Central Indian River Lagoon Basin Management Action Plan, February 2021
The outputs of this modeling effort can be described as static feature classes that include more
than 1.2 million 50 x 50-m cells (as features) each. Each individual cell is associated with an
estimated volume and both nitrogen and phosphorus estimated loading for the selected mean
period -of -record conditions (Applied Ecology 2018).
For land use and land cover, 2015 conditions were represented as derived from water
management district data for nonurban land uses and from local property appraiser datasets for
urban land uses. Natural community data from local governments were also incorporated, where
available (Brevard County). In addition, field -validated 2015 land use datasets for Patrick Air
Force Base, Cape Canaveral Air Force Station, and the Malabar Annex were used in lieu of
water management data (Applied Ecology 2018). Land covers were grouped to reflect the
available event mean concentrations (EMCs) and C values that would be applied in the model.
(Listopad 2020).
DEP used the LET to develop the allocations (see Figure 7 and Figure 8). The percent reduction
from the TMDLs was applied to the applicable areas within the BMAP. The TMDL percent
reductions are based on segmented areas of the lagoon defined by both DEP WBIDs, along with
breaks in the hydrology of the lagoon as defined by SJRWMD. Areas where segments share
hydrologic similarity and similar reduction percentages, as noted by the TMDLs, are defined as
segment groups. Additionally, during the first phase of BMAP adoption, the hydrology defined
by SJRWMD was used to define project zones in order to assess seagrass compliance. Project
zones were used to assist in calculating the required reduction and the allocation of each entity
within the BMAP. In the CIRL, the total project zone load from the LET was used, and the
percent reduction from the TMDL for that project zone was applied to determine the total
required reductions per project zone. Natural lands had no reductions applied, and so the SWIL
loads from natural land uses were held constant. The land cover codes considered to be "natural
lands" include 3000 (upland nonforested; not including 3300), 4000 (upland forests), 5000
(water), and 6000 (wetlands). The allowable load in the project zone was determined by
subtracting the required reductions from the total project zone load determined by the LET.
A test was performed to make sure that no reductions would be expected from natural land uses.
The weighted average load per acre from natural lands for each project zone was compared with
the load per acre from the allowable load. If the allowable load per acre was less than the natural
land load per acre, the allowable load was increased to equal the natural load per acre times the
acres in the project zone. This process was performed for both TN and TP loads in each project
zone. The TN loads were adjusted using the natural load per acre for Project Zones A, B, and
SEB. The TP loads were adjusted using the natural load per acre for Project Zone SIRL.
Once the total required reductions for each project zone were defined, the total anthropogenic
load for the project zone was examined. Each stakeholder's anthropogenic load was compared
with the total anthropogenic load for the project zone to determine its contribution to the total
anthropogenic load. This percentage was considered to be representative of the stakeholder's
loading contribution, and that percentage of the project zone's required reduction was applied to
that stakeholder.

2.2.1.1. Low -Priority Ranking Determination
Several stakeholders contribute less than 0.30 % of both the TN and TP loading from the
watershed to the CIRL. The contribution to the overall nutrient loading from these stakeholders
is low enough that reductions from these areas would have essentially no impact on the required
reductions for the BMAP during this phase of implementation; therefore, these entities are
currently considered a low priority for implementing reductions. Low -priority entities will be
evaluated in future phases of BMAP implementation, as their contributions may change over
time.
Table 13 summarizes the priority evaluation, and those stakeholders meeting the classification
requirements for low priority are highlighted in grey. Stakeholders that met the low -priority
classification include the Town of St. Lucie Village, Town of Indialantic, Town of Melbourne
Village, Town of Orchid, City of Fort Pierce, U.S. Air Force, and Florida Turnpike. These
entities are not required to meet the reduction targets for TN and TP in this phase of BMAP
implementation but must continue to adhere to all requirements of its MS4 permit or other
permits.
BMAP progress will be reviewed over time, and reduction requirements, including for those
stakeholders with this low -priority status, will be modified in a future BMAP update as needed.
TN and TP reductions may be needed from the low -priority entities in the future. Therefore,
although they do not currently have a reduction responsibility, this does not exempt these
stakeholders from such requirements in future BMAP updates. Any actions taken by these
entities that result in TN and TP reductions will be documented for credit against any reduction
requirements allocated in subsequent BMAP updates.

2.3 Basinwide Sources Approach
The basinwide sources approach involves tailoring management strategies to the primary sources
of anthropogenic nutrient loading throughout the CIRL Subbasin. The primary source categories
included in this approach are agricultural runoff, septic systems, urban stormwater, and
wastewater. For additional information on other sources not directly addressed through
anthropogenic activities, please refer to Section 1.2.4.
Page 57 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
2.3.1. Agriculture
When DEP adopts a BMAP that includes agriculture, it is the agricultural landowner's
responsibility to properly implement BMPs adopted by FDACS to help achieve load reductions
or demonstrate compliance through monitoring. The current enrollment is 25 % of agricultural
acres identified in the BMAP (see Appendix Q. FDACS is undertaking efforts to transmit
enrollment notifications to producers and landowners on identified agricultural lands within the
BMAP area, which will drive increased enrollment or referral to DEP for water quality
monitoring. A more detailed characterization of unenrolled agricultural lands is found in
Appendix C. FDACS is responsible for verifying that all eligible landowners are enrolled in
appropriate BMP programs. Subparagraph 403.067(7)(d)3, F.S. requires FDACS to perform
regular onsite inspections, at least every two years, of all agricultural operations enrolled under a
BMP manual to ensure that these practices are being properly implemented. Per the requirements
of the statute, FDACS is prioritizing implementation verification (IV) efforts in certain basins,
including the IRL. From these inspections, FDACS will provide DEP with an annual summary of
aggregated fertilizer use in the BMAP area, quantifying total applications and providing
information on applications by project zone.
It is anticipated that additional enrollment in agricultural BMPs, along with more frequent
implementation verification site visits by FDACS, will increase nutrient reductions from
agricultural nonpoint sources. However, further reductions beyond the implementation of
required owner -implemented BMPs currently required by the FDACS manuals, may be
necessary to achieve the TMDLs. FDACS has committed to updating its existing BMP manuals
to incorporate updated BMPs based on the latest scientific and technical research. Subparagraph
403.067(7)(f)1, F.S., requires FDACS to annually develop research plans and legislative budget
requests for the following:
• Evaluate and suggest enhancements to the existing adopted agricultural BMPs
to reduce nutrient runoff.
• Develop new BMPs that, if proven effective, may be adopted by rule.
• Develop agricultural nutrient runoff reduction projects that willing
participants could implement on a site -specific, cooperative basis, in addition
to BMPs.
FDACS also provides funding to some agricultural operations to add other practices beyond
owner -implemented BMPs. Examples include drainage improvements, fencing, water control
structures, precision agriculture technology, and fertigation. SFWMD and SJRWMD are
implementing and/or funding projects that encourage low -input agriculture and the use of water
quality improvement technologies.
If owner -implemented BMPs fail to achieve water quality improvements, a cooperative
agricultural regional water quality improvement element may be developed for this BMAP,
subject to the conditions outlined in Subparagraph 403.067(7)(e)1, F.S. DEP, FDACS, and
Page 58 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
agricultural producers will cooperatively develop a regional water quality improvement element
in the event of the following:
• Agricultural measures have been adopted by FDACS pursuant to
Subparagraph 403.067(7)(c)2, F.S., and have been implemented and the
waterbody remains impaired.
• Agricultural nonpoint sources contribute to at least 20 % of nonpoint source
nutrient discharges.
• DEP determines that additional measures, in combination with state -
sponsored regional projects and other management strategies included in the
BMAP, are necessary to achieve the TMDLs.
Further nutrient reductions can be achieved through the implementation of additional agricultural
projects or activities. Other reductions associated with the implementation and modification of
BMPs may be realized through ongoing studies, data collection, and water management district
initiatives. These additional projects and practices are to be implemented in conjunction with the
BMP Program, which will aim to achieve full enrollment with verification to ensure that the
BMAP goals are achieved.
2.3.2. Septic Systems
As required in Subsubparagraph 403.067(7)(a)9.b., F.S., local governments must develop an
onsite sewage treatment and disposal system (OSTDS) remediation plan to be adopted as part of
the BMAP no later than July 1, 2025. The OSTDS remediation plans must be developed by each
local government in cooperation with DEP, FDOH, water management districts, and public and
private domestic wastewater facilities.
The OSTDS remediation plan requires entities to identify and address the following:
• Cost-effective and financially feasible projects necessary to achieve the
nutrient load reductions required for OSTDS (e.g., sewering, advanced septic
system retrofits, prohibiting the installation of new conventional septic
systems).
• An inventory of OSTDS based on the best information available.
• OSTDS that would be eliminated through connection to existing or future
central domestic wastewater infrastructure in the jurisdiction or domestic
wastewater service area of the local government.
• OSTDS that would be replaced with or upgraded to enhanced nutrient -
reducing systems.
• Cost of improvements and sources of funding.
Page 59 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
Based on data from FDOH, there are 78,363 known and likely septic systems located throughout
the CIRL Subbasin. Table 9 in Section 1.2.1.3 summarizes the count of septic systems by
project zone.
Stakeholders will submit projects describing how septic loads are addressed as part of BMAP
reporting and estimate the load reductions associated with each project. The estimated reductions
to the lagoon from addressing these septic systems will be based on several factors, including
how they are addressed (i.e., connecting to central sewer sends the wastewater to a treatment
facility, which does not remove 100 % of the nutrient load) and the amount of attenuation that
occurs as the effluent travels through the watershed to the lagoon.
2.3.3. Stormwater
Stormwater from urban areas is a considerable source of nutrient loading to the CIRL, and many
of these areas are already regulated under the NPDES Stormwater Program. MS4 permittees are
required to develop and implement a stormwater management program. Urban areas located in
the BMAP area that are not currently covered by an MS4 permit also significantly contribute,
individually or in aggregate, to nutrient loading. Therefore, the NPDES Stormwater Program
will, within 5 years of BMAP adoption, evaluate any entity located in the BMAP area that serves
a minimum resident population of at least 1,000 individuals that is not currently covered by an
MS4 permit and designate eligible entities as regulated MS4s, in accordance with Chapter 62-
624, F.A.C.
In accordance with Subsection 373.4131(6), F.S., DEP and the water management districts are
planning to update the stormwater design and operation requirements in Environmental Resource
Permit rules. These revisions will incorporate the most recent scientific information available to
improve nutrient reduction benefits.
2.3.4. Wastewater Treatment
DEP issues permits for facilities and activities to discharge wastewater to surface waters and
groundwaters of the state. DEP is authorized by the EPA to issue permits for discharges to
surface waters under the NPDES Program. Permits for discharges to groundwater are issued by
DEP under state statutes and rules. These wastewater discharge permits establish specific
limitations and requirements based on the location and type of facility or activity releasing
industrial or domestic wastewaters from a point source.
As of September 2020, there were 41 individually permitted wastewater facilities or activities in
the CIRL Subbasin. All new or existing wastewater facilities that dispose of or discharge effluent
in the BMAP area are subject to the BMAP provisions, regardless of whether the facility is listed
in this BMAP. A preliminary list of wastewater facilities in the CIRL as of September 2020 is
provided in Table 11, and a map of their locations is shown in Figure 3 in Section 1.2.1.5.
In areas where there is anticipated growth in human population, adequate treatment capacity of
domestic wastewater is essential. Domestic wastewater is treated through either WWTFs or
OSTDS (septic systems). Where sewer lines are available, Florida law (Section 381.00655, F.S.)
Page 60 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
requires a development or property owner to abandon the use of OSTDS and connect to sanitary
sewer lines.
Florida law (Section 403.086, F.S., and Chapter 2020-150, Laws of Florida) requires all existing
and new domestic wastewater facilities discharging to surface waters of the state within or
connected to the IRL to meet advanced waste treatment requirements, as defined in Section
403.086, no later than July 1, 2025. Additionally, this BMAP requires all other individually
permitted domestic wastewater facilities to meet the effluent limitations listed in Table 16 and
Table 17, unless the owner or operator can demonstrate reasonable assurance that the effluent
would not cause or contribute to an exceedance of the TMDLs or water quality standards in
groundwater.
To demonstrate reasonable assurance, the owner or operator must provide relevant water quality
data, physical circumstances, or other site -specific credible information needed to show the
facility would not cause or contribute to the nutrient loading in the BMAP area. This
demonstration may include factors such as dilution; site -specific geological conditions;
research/studies, including dye tracer tests; and modeling. If DEP concurs with the reasonable
assurance demonstration, the effluent limitations established for discharges to ground water may
be modified or waived for the facility. New effluent limitations will take effect no later than July
1, 2025.
New and existing domestic wastewater facilities must meet the stringent nutrient wastewater
limitations set forth in this BMAP. Any such new facilities (those commencing after the adoption
of this BMAP) must be capable of meeting the requirements of this BMAP at the time of permit
issuance. For existing domestic wastewater facilities, DEP shall modify the permit limitations
and requirements to be consistent with this BMAP at the time of the next permit renewal. If the
facility needs additional time to meet the new limits, the permit may include a compliance
schedule with a completion date not to exceed four and a half years after the effective date of the
permit.
Table 16 and Table 17 list the TN and TP effluent limitations, respectively, adopted for this
BMAP that apply to domestic wastewater facilities unless the owner or operator can demonstrate
reasonable assurance as listed above. The effluent limitations for direct surface water discharges
and reclaimed water pipelines apply to individually permitted NPDES facilities at the end -of -
pipe. Because the limitations for direct surface water discharges are technically -based advanced
waste treatment limitations, mixing zones are not authorized for TN and TP. The effluent
limitations for discharges to groundwater apply at the compliance well located at the edge of the
zone of discharge. The owner or operator may elect to meet the groundwater limitations prior to
the edge of the zone of discharge. These effluent limitations are applied as an annual average.
For direct surface water discharges, the limitations in Paragraph 62-600.740(2)(b), F.A.C., will
be applied in the permit.
Short-term or intermittent industrial discharges are not significant sources of TN or TP in the
CIRL Subbasin and are not subject to the limits in Table 16 and Table 17. Intermittent, rainfall -
Page 61 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
driven, diffuse overflow releases of wastewater from ponds or basins designed to hold
precipitation from a 25-year, 24-hour rainfall event or less frequent rainfall event and that
infrequently reaches surface waters are considered insignificant sources of TN and TP, provided
the ponds or basins are maintained under normal conditions at or below established water levels.
The owners or operators of cooling pond reservoirs must operate each spillway gate either during
regular operation or on a test basis to protect the structural integrity of the reservoir. Because of
the short duration and low volume of wastewater released during spillway gate testing, releases
either on an annual or semiannual basis are considered insignificant sources of TN and TP.
Existing industrial wastewater facilities are not subject to the limits in Table 16 or Table 17.
However, these facilities must hold the line and shall not increase the nutrient load to receiving
or downstream waters. New industrial wastewater facilities shall meet the limits in Table 16 and
Table 17. For industrial wastewater facilities that discharge to surface waters of the state must
meet the numeric nutrient criteria in Rules 62-302.531 and 62-302.532, F.A.C.
Additionally, new or renewed wastewater permits in the BMAP area must require at least
quarterly sampling of the effluent at the point of discharge or edge of the zone of discharge for
TN and TP and the reporting of sampling results in the discharge monitoring reports submitted to
DER

Central Indian River Lagoon Basin Management Action Plan, February 2021
Pursuant to Subsubparagraph 403.067(7)(a)9., F.S., local governments in BMAP areas
where DEP determines remediation is necessary to achieve the TMDL must develop
wastewater treatment plans to be adopted as part of the BMAP no later than July 1, 2025,
when all effluent is required to meet the TN and TP concentrations for Direct Surface
Discharge cited in Table 16 and Table 17.
The wastewater treatment plans must be developed by each local government, in
cooperation with DEP, the water management district, and the public and private
domestic wastewater treatment facilities within the jurisdiction of the local government.
A local government is not responsible for a private domestic wastewater facility's
compliance with the BMAP unless the facility is operated through a public -private
partnership to which the local government is a party.
The wastewater treatment plan requires entities to identify and address the following:
• Provide construction, expansion or necessary facility upgrades to achieve the
TMDLs applicable to the domestic WWTF.
• Include the permitted capacity in annual gallons per day for the domestic
WWTF.
• Include the average nutrient concentration and the estimated average nutrient
load of the domestic wastewater.
• Provide a project timeline of the date when the construction of any facility
improvements will begin and be completed and the date when operations of
the improved facility will begin.
• Estimate the cost of improvements.
• Identify the responsible parties.
2.4 Seagrass and Water Quality Monitoring Plan
This monitoring plan is designed to track seagrass distribution and to identify long-term water
quality trends. Sampling stations, parameters, frequency, and other elements of this strategy may
be modified as appropriate to match changing environmental conditions, funding resources, and
understanding of the IRL system.
2.4.1. Objectives
The primary and secondary monitoring objectives for the CIRL monitoring plan are described as
follows:
Primary Monitoring Objective
Page 63 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
• Track seagrass depth extent responses to BMAP implementation.
Secondary Monitoring Objectives
• Track trends in ambient water quality in the CIRL and its watershed,
including major tributaries.
• Determine if watershed nutrient loading is decreasing and resulting in
improved lagoon water quality, which will allow seagrass to grow to target
depths.
Additional information about the seagrass depth and compliance with the TMDL targets is
discussed in Section 4.2, including the most recent results based on the 2019 aerial mapping
data. To read more about the process for analyzing the seagrass data and depth analysis, see
Appendix D.
2.4.2. Monitoring Parameters, Frequency, and Network
To achieve the primary monitoring objective, the main parameter that will be tracked is the
seagrass depth by project zone, which is identified through flyover mapping and aerial
photography interpretation. DEP and SJRWMD are partnering to fund and conduct flyovers and
mapping. In the past, SJRWMD and partners typically have contracted for seagrass mapping
every two to three years, and DEP will continue to work with the district to maintain this
frequency for the BMAP monitoring plan as long as resources remain available.
The aerial photography is taken in spring to early summer, during the seagrass growing season.
Field sampling conducted around the time of the flights provides data for assessing the accuracy
of the maps, and additional field sampling is conducted to address uncertainty regarding areas
mapped as seagrass. Using the aerial photography, a map is created showing seagrass extent in
the lagoon. These maps are used in evaluations to assess progress towards the TMDL seagrass
depth targets for the CIRL. Additional details on the seagrass assessment methodology are
contained in Appendix D.
To achieve the secondary monitoring objective above, the existing SJRWMD and SFWMD
stations in the CIRL BMAP will be monitored. On average, seagrass transects are 1 kilometer
(km) away from a long-term water quality station. The monitoring strategy for these stations
focuses on the following parameters:
• Total Kjeldahl Nitrogen.
• Nitrite/Nitrate.
• Ammonia.
• Total Nitrogen (TN).
• Total Phosphorus (TP).

• Orthophosphate.
• Chlorophyll a (corrected).
• Photosynthetically Active

• Water Temperature.
• Field Conditions.
• Total Organic Carbon.

• Silica.
• Alkalinity.
• Volatile Suspended

In addition to the SJRWMD and SFWMD water quality monitoring stations, long-term stations
are monitored by the Indian River Farms Water Control District (IRF-WCD), North St. Lucie
River WCD (NSLR-WCD) Fort Pierce Farms WCD (FPF-WCD), and Sebastian River
Improvement District (SRID) for water quality, and U.S. Geological Survey (USGS) for flow.
Table 18 lists the stations that SJRWMD, USGS, IRF-WCD, NSLR-WCD, FPF-WCD, and
SRID currently sample in the CIRL BMAP area, and these stations are shown by project zone in
Figure 9 through Figure 12. Data collection generally occurs from three types of stations: flow
stations where volume is primarily determined; tributary water quality stations near the junction
of tributaries where parameters are sampled as these waters mix with the lagoon; and lagoon
water quality stations that measure parameters in the lagoon itself.

Central Indian River Lagoon Basin Management Action Plan, February 2021
BMAP data analyses and adaptive management evaluations. Data used to assess the biological
health of streams and lakes may be provided to DEP staff in the Watershed Assessment Section.
For more information on submitting external biological data, visit the DEP website.
The water quality data will be analyzed periodically to determine trends in water quality in the
lagoon. Specific statistical analyses were not identified during BMAP development; however,
commonly accepted methods of data analysis will be used.
2.4.4. Quality Assurance/Quality Control
Stakeholders participating in the monitoring plan must collect water quality data in a manner
consistent with the DEP standard operating procedures (SOPS) for QA/QC. The most current
version of these procedures can be downloaded from the DEP website. For BMAP-related data
analyses, entities should use National Environmental Laboratory Accreditation Council
(NELAC) National Environmental Laboratory Accreditation Program (NELAP)—certified
laboratories or other labs that meet the certification and other requirements outlined in the DEP
SOPs. SJRWMD staff and contractors collect, process, and preserve samples according to
SJRWMD's Field Standard Operating Procedures for Surface Water Sampling Fiscal Year
2020. SFWMD staff and contractors collect, process, and preserve samples according to
SFWMD's Field Sampling Quality Manual.
2.5 Research Priorities
During the BMAP process, the stakeholders identified several research priorities they would like
to pursue, if funding becomes available. The investments prompted by the 2011 superbloom
generated research topics that include the following:
• Collecting data to update the bathymetry for the IRL Basin, which would be
used in evaluations of seagrass depth limits.
• Continuing coordinated monitoring of phytoplankton, periphyton, drift algae,
and macroalgae in the basin to gain insights into the cycling of nutrients as
well as toxin production and release.
• Data analysis of storm event monitoring at the major outfalls.
• Collecting data on the nutrient load reduction that results from WCD staging/
retaining stormwater runoff.
• Refining load estimates delivered by baseflows and modeling the
contributions of baseflows.
• Synthesizing data on nutrient flux/intemal recycling of legacy nutrient loads
held within IRL sediments and exchanged with the water column.
Page 72 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
• Completing the development, calibration, and validation of a water quality
model that can be used to design, site, and prioritize projects that reduce
nutrient loads (e.g., Hydrologic Simulation Program FORTRAN [HSPF] or
SWIL Model coupled with the Environmental Fluid Dynamics Code [EFDC]
Model or another model that generates predictions of conditions that may be
favorable for seagrass growth).
The stakeholders will continue to work with DEP and IRL NEP to identify other research needs,
prioritize these needs, and develop scopes of work to address research priorities as appropriate.
This information may be organized in a more detailed research plan that could be used to guide
future efforts, as funding becomes available. These research projects are not BMAP requirements
but would provide valuable information for future assessments of the health of the CIRL. There
are reports and peer -reviewed articles that have been completed to address several of these research
priorities. References are provided in Chapter 5.
Page 73 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
Chapter 3. Project Zones
Section 3.1 through Section 3.4 provides specific land use and project information on the four
project zones in the CIRL. All projects identified as part of this BMAP are listed by project zone.
For projects that treat lands in multiple project zones, the nutrient reductions provided in the
table are only the estimated reductions for the project zone specified. To calculate the total
benefits from these projects, credits from all project zones treated by the project should be
summed. The table of existing and planned projects lists those projects submitted by stakeholders
to help meet their obligations under the BMAP. Information in the tables was provided by the
lead entity and is subject to change as the project develops and more information becomes
available.
It should be noted that only projects completed in 2000 and beyond are eligible for BMAP credit.
Since the treatment input data for the hydrology calibration was from an earlier period in the
model simulation, most projects beyond permit requirements installed from 2000 onward were
not included in the calibration and are not well represented in the SWIL Model loading
estimates. Therefore, projects completed from 2000 onward are eligible for BMAP credit.
Projects completed prior to 2000 are accounted for in the period of record used for calibration of
the SWIL Model.
The projects and management strategies are ranked with a priority of high, medium, or low.
Projects with a "completed" status were assigned a low priority. Projects classified as
"underway" were assigned a medium priority because some resources have been allocated to
these projects, but additional assistance may be needed for the projects to be completed. A high
priority was assigned to projects listed as "planned," as well as certain "ongoing" projects (i.e.,
"street sweeping," "catch basin inserts/inlet filter clean out," "public education efforts," "fertilizer
cessation," "fertilizer reduction," or "aquatic vegetation harvesting").
3.1 Project Zone A
Project Zone A covers more than 94,742 acres of the CIRL BMAP. As shown in Table
19, urban land uses makes up the majority of the project zone with 55.4 % of the area,
followed by shrublands with 12.2%. Stakeholders in Project Zone A are agricultural
producers, Brevard County, City of Melbourne, City of Palm Bay, City of Melbourne,
FDOT District 5, Melbourne -Tillman WCD, Town of Melbourne Beach, Town of Grant-
Valkaria, Town of Indialantic, Town of Malabar, Town of Melbourne Village, and U.S.
Air Force (Malabar Annex).

DEP asked stakeholders to provide information on management actions, including projects,
programs, and activities, that may reduce nutrient loads to the CIRL. Management actions are
included in the BMAP to address nutrient loads to the lagoon and have to meet several criteria to
be considered eligible for credit. Figure 15 and Figure 16 show progress towards the required
TN and TP load reductions allocated to Project Zone SEB from projects completed through July
31, 2020.

3.3 Project Zone B
Project Zone B covers more than 68,938 acres of the CIRL BMAP area. As listed in Table 23,
urban land uses makes up the majority of the project zone with 55.6 % of the area, followed by
agriculture with 19.3 %. Stakeholders in Project Zone B are agricultural producers, City of Vero
Beach, FDOT District 4, Fort Pierce Farms WCD, Indian River County, Indian River Farms
WCD, and Town of Indian River Shores.
Table 23. Summary of land uses in Project Zone B
Note: Land use code 5000 (water) acreage excludes lagoon water in this table.
Level
7DEP asked stakeholders to provide information on management actions, including projects,
programs, and activities, that may reduce nutrient loads to the CIRL. Management actions are
included in the BMAP to address nutrient loads to the lagoon and have to meet several criteria to
be considered eligible for credit. Figure 17 and Figure 18 show progress towards the required
TN and TP load reductions allocated to Project Zone B from projects completed through July 31,
2020.

3.4 Project Zone SIRL
Project Zone SIRL covers more than 34,653 acres of the CIRL BMAP area. As shown in
Table 25, urban land uses makes up the largest portion of the project zone with 40.6 % of
the area, followed by agriculture with 29.2 %. Stakeholders in Project Zone SIRL are
agricultural producers, City of Fort Pierce, FDOT District 4, Florida Turnpike Enterprise,
Fort Pierce Farms WCD, St. Lucie County, and Town of St. Lucie Village. TMDLs have
not yet been developed by DEP for the impaired waterbodies in the SIRL, although there
are some tributary TMDLs in this area, as outlined in Section 1.1.1.
Table 25. Summary of land uses in Project Zone SIRL
Note: Land use code 5000 (water) acreage excludes lagoon water in this table.
7 Lev
d Use Code el l
DEP asked stakeholders to provide information on management actions, including projects,
programs, and activities, that may reduce nutrient loads to the CIRL. Management actions are
included in the BMAP to address nutrient loads to the lagoon and have to meet several criteria to
be considered eligible for credit. Figure 19 and Figure 20 show progress towards the required
TN and TP load reductions allocated to Project Zone SIRL from projects completed through July
31, 2020.

Chapter 4. Compliance and Adaptive Management
4.1 Future Growth
To ensure that this BMAP effort can achieve and ultimately maintain the goal of meeting TMDL
requirements, the overall restoration strategy must include actions and planning for future growth
and development. Any new development would likely fall into two general source categories: (1)
urban and (2) agricultural. Nutrient impacts from new development will be addressed through a
variety of mechanisms as well as other provisions of Florida law.
While the majority of the restoration projects and programs listed in this BMAP address current
loading, the need to plan and implement sound management strategies to address additional
population growth in the BMAP area must be considered. DEP has included in this BMAP
specific elements to address all current and future WWTF effluent, septic systems, and
stormwater sources. Broader laws —such as local land development regulations, comprehensive
plans, ordinances, incentives, Environmental Resource Permit requirements, and consumptive
use permit requirements —all provide additional mechanisms and avenues for protecting water
resources and reducing the impact of new development and other land use changes as they occur.
As more information becomes available, the modeling efforts used for determining loading to the
lagoon will continue to be refined.
The recommendations presented in Chapter 2 should be considered by local governments during
master planning and land use decision -making efforts. It should also be noted that any additional
loading, such as from land use changes from low to high density, or any increase in intensity of
use (that may include additional nutrient loadings), will be evaluated during future BMAP
review efforts. If an increase in loading has occurred, additional restoration actions will be
required to remediate impacts. DEP recommends that all local governments revise their planning
and land use ordinance(s) to adequately address all future growth, and consider limitations on
growth in sensitive areas, such as lands with a direct hydrologic connection to impaired
waterbodies, wetland areas, or coastal areas.
4.2 Compliance
4.2.1. TMDL Compliance
The intent of the TMDLs is to recover the deeper water seagrass habitats, with the biological
response of the seagrass being the most important factor in evaluating the success of achieving
TMDL targets. To assess progress for the IRL Basin towards the median seagrass depth limit
target, a two-step process was used in the A, B, and SEB Project Zones. TMDL targets for Steps
I and 2 were not established for the lagoon in the SIRL project zone, and so it is excluded from
this analysis. For the 2013 BMAP, DEP conducted this two-step evaluation using seagrass data
from 2003, 2005, 2006, 2007, and 2009, which were the latest datasets available at the time of
the analysis. For the CIRL, all three project zones were determined to be both Step 1 and Step 2
compliant in 2013. Therefore, stakeholders in the CIRL were not required to make additional
Page 130 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
reductions at the time and were not assigned detailed allocations in the first iteration of the
BMAP.
Since the 2013 BMAP, further evaluations of the seagrass depth limits in the CIRL have been
conducted to reassess whether the CIRL project zones have continued to be compliant.
Table 27 and Table 28 list the results of both steps of these evaluations since 2013, including the
number of years that passed Step 2 of the evaluation. In 2020, the evaluation was conducted
using the 2013, 2015, 2017, and 2019 seagrass mapping data, which were the latest datasets
available at that time. Figure 21 through Figure 23 show the results of both steps of the 2020
evaluation for Project Zones A, SEB, and B respectively. None of the 3 project zones with
TMDLs was compliant. As indicated in the 2013 BMAP, DEP assigns detailed allocations in
project zones where compliance is not maintained.

4.2.2. BMAP Compliance
In addition to IRL TMDL compliance and the measurement of seagrass deep edge recovery,
there are other compliance elements related to the BMAP. DEP has set BMAP TN and TP
reduction milestones for the years 2025 and 2030 to ensure that significant progress will be made
in each five-year increment prior to the 2035 total reduction deadline. The percent reductions in
the milestones apply to the total BMAP required reductions; so as various entities implement
their projects, the overall milestones are also being met. Individual entities must achieve
compliance by meeting their own required reductions by the 2035 deadline, as well as show
progress towards the BMAP milestones by planning and implementing projects.

Appendices
Appendix A. BMAP Projects Supporting Information
The project tables in this BMAP (Table 20, Table 22, Table 24, and Table 26) list the
implementation status of the BMAP projects as of July 31, 2020. The tables list the TN and TP
reductions in lbs/yr attributable to each individual project. These projects were submitted to DEP
by responsible entities with the understanding that the projects and activities would be included
in the BMAP, thus setting the expectation for each entity to implement the proposed projects and
activities to achieve the assigned load reduction estimates in the specified time.
However, the list of projects is meant to be flexible enough to allow for changes that may occur
over time. During the annual review of BMAP implementation efforts, project -specific
information may be revised and updated, resulting in changes to the estimated reductions for
those projects. The revisions may increase or decrease estimated reductions, and DEP will work
with stakeholders to address revisions as they are identified.
The project status column is standardized into the following five categories:
• Canceled: Project or activity that was planned but will no longer take place.
This category includes the cessation of ongoing activities.
• Completed: Project, activity, or task that is finished. This category includes
fully implemented activities (i.e., ongoing activities) that must continue to
maintain assigned credits indefinitely (such as street sweeping, BMP cleanout,
catch basin cleanout, public education, fertilizer cessation/reduction, and
vegetation harvesting).
• Planned: Project or activity that is conceptual or proposed.
• Underway: Project or activity that has commenced or initiated but is not
completed and is not yet reducing nutrient loads from the treated area.
• Ongoing: The lead entity is performing actions each year. This status is used
when a project is typically nonstructural and continuous. Ongoing projects are
not a continuation of a reduction for a structural project.
Prior to reporting project information, DEP contacts each lead entity to gather new information
on projects and confirm previously reported information. The terms used throughout the project
tables are defined as follows:
• Not provided: Denotes that information was requested by DEP but was not
provided by the lead entity.
Page 135 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
• TBD: To be determined. Denotes that information is not currently available
but will be provided by the stakeholder when it is available.
• N/A: Not applicable. Denotes that information for that category is not relevant
to that project.
• 0: Zero. Denotes the numeric value for that category as zero.
The project tables are based on current information, and project details may be updated as further
information becomes available.
This BMAP requires stakeholders to implement their projects to achieve reductions as soon as
practicable. However, the full implementation of the BMAP will be a long-term process. While
some of the projects and activities listed in the BMAP were recently completed or are currently
ongoing, several projects require more time to design, secure funding, and construct. Unlike the
existing and planned projects, these future projects are not yet considered commitments of the
entities but rather are intended for future BMAP credit, pending the availability of funding and
other resources.
Although BMAP implementation is a long-term process, the goal of this BMAP is to achieve the
TMDLs by the 2035 milestone. It is understood that all waterbodies can respond differently to
the implementation of reduced loadings to meet applicable water quality standards. Continued
coordination and communication by the stakeholders will be essential to ensure that management
strategies continue to meet the implementation milestones.

Appendix B. Central IRL Allocation Calculations
The first step in the allocation process was to establish the total TN and TP load, by project zone,
from the SWIL Model. This is an important step because the watershed loads to each segment
are based on the updated information and model refinements incorporated in the SWIL Model.
Starting loads for Project Zone A were adjusted to account for the impact of the C-1 diversion
project, which redirects flow to the St. John's River and away from the IRL. Table B-1 below
lists the TN and TP starting loads from the SWIL Model for each project zone and the associated
acres of watershed in that segment.

The TMDLs for the IRL (in Rule 62.304.520, F.A.C.) include a percent reduction from the
starting load for TN and TP.
Table B-2 describes the TMDL rule percent reduction for each project zone and lists the WBIDs
included in each project zone.

The second step in the allocation calculations was to apply the TMDL percent reduction (
Table B-2) for TN or TP to the starting load (Table B-1), respectively. Table B-3 lists the TN
and TP reductions needed to meet the TMDL based on these calculations. The allowable load
after the reductions are met is called the allocation. To calculate the TN allocation and the TP
allocation in the table below, the TN reduction or TP reduction is subtracted from the TN or TP
starting load in Table B-3.

Now that the total reductions are calculated with the TMDL percent reductions, a test is
completed to ensure there are no requirements to make reductions from natural land uses. To test
whether the calculated reductions would go beyond reductions for converted land uses
(anthropogenic land uses), DEP calculated the weighted average load per acre of natural lands
(natural load per acre) in each project zone. The natural load per acre values were calculated
from loads associated with natural lands in the initial model output. Any land use adjustments
that were later incorporated into the allocation process were not accounted for in the natural load
per acre calculations. Table B-4 outlines the data that were used to calculate the natural load per
acre for TN and TP. The acreage and the weighted average loading from only the natural lands
were calculated from the SWIL Model, by project zone. The loading for TN and TP was divided
by the acres of natural lands, respectively, to derive the natural load per acre and the values were
rounded. These natural loads per acre were compared with the allowable loads per acre, as
shown in Table B-5.

DEP then calculated the allowable load per acre for each project zone. This is the allocation load
divided by the acres in the project zone. The allowable load is calculated for both TN and TP and
compared with the weighted average load per acre of natural lands (natural load per acre) in that
project zone. If the allowable load per acre is less than the natural load per acre, an adjustment is
made. In Table B-5 below, the allowable loads per acre for TN and TP are shown and "True" is
entered if the allowable load per acre is less than the natural load per acre. When the test is
"True," an adjustment is made for the TN reduction, TP reduction, or both.

When an adjustment was indicated, the reductions were then adjusted by taking the starting loads
from Table B-1 and subtracting the adjusted allowable load and adjusting the reductions listed
previously in Table B-3. Only those reductions noted as needing a adjustment (see Table B-5)
were adjusted. A summary of the TN and TP reductions (adjusted, if applicable) and the TN and
TP allocations are listed in Table B-6.

After the reductions are calculated for each project zone, the relative starting load in the project
zone for each stakeholder is used to assign the entity reductions. The natural lands are separated
from each entity's area to assess the relative anthropogenic contributions, so that stakeholders
would not be asked to reduce loads from natural lands in their jurisdiction. In Table B-7, Table
B-8, Table B-9, and Table B-10, natural lands are separated from the starting loads, and so only
the anthropogenic loadings are included in the entity loads.

After the natural lands were separated from the entity loading estimates based on the SWIL
Model, the relative contribution of each entity to the total project zone anthropogenic load was
calculated. Table B-11, Table B-12, Table B-13, and Table B-14 show the percent contribution
within the project zone to anthropogenic TN and TP, respectively, by entity. The TN
contribution percentage is calculated by dividing the entity anthropogenic TN load by the total
anthropogenic TN segment load, and then a similar calculation is performed for each entity's TP
load.

For the unadjusted project zones (for TN, Project Zone SIRL is unadjusted, and for TP, Project
Zone A, Project Zone SEB, and Project Zone B are unadjusted), each entity's reduction was
calculated by multiplying the total project zone starting load (Table B-1) by the project zone
required reduction (Table B-3) and by the entity's percent contribution to anthropogenic loading,
as defined in Table B-11, Table B-12, Table B-13, and Table B-14. The calculations for the
entity reductions were performed separately for TN and TP. Then, the entity TN and TP
allowable loading (allocations) was then computed by subtracting the entity required reductions
in Table B-15, Table B-16, Table B-17, and Table B-18 from the entity anthropogenic starting
loads (Table B-11, Table B-12, Table B-13, and Table B-14).

For some project zone calculations (for TN, Project Zones A, SEB, and B, and for TP, Project
Zone SIRL), the entity reductions and allowable loads were calculated differently to incorporate
the natural load per acre adjustment. Here, the project zone allocation was calculated by
multiplying the acres in the project zone (Table B-4) by the project zone natural load per acre
(Table B-4). Next, the entity allocation was computed by multiplying the adjusted project zone
allocation (Table B-6) by the entity percent contribution to anthropogenic loading (Table B-11,
Table B-12, Table B-13, and Table B-14). Once the entity allocation was known, then the entity
reduction was calculated by subtracting the entity allocation from the entity starting load. The
reductions and allocations are shown in Table B-19, Table B-20, Table B-21, and Table B-22.

As described above, the entity calculations were performed by project zone. Once these were
complete, the information was summarized by entity. In Table B-23, the starting loads for each
entity are totaled across all the project zones in which they have a land area. Also listed are their
relative percentages of anthropogenic load for TN and TP, respectively, in the BMAP area.
Seven stakeholders contribute less than 0.30 % of both the TN and TP loading from the
watershed to the NIRL. The contribution to the overall nutrient loading from these stakeholders
is low enough that reductions from these areas would have essentially no impact on the required
reductions for the BMAP during this phase of implementation; therefore, these entities are
currently considered a low priority for implementing reductions. Low -priority entities will be

evaluated in future phases of BMAP implementation, as their contributions may change over
time.

Appendix C. Agricultural Enrollment and Reductions
(Language in this appendix was provided by FDACS)
All agricultural nonpoint sources in the CIRL BMAP area are statutorily required either to
implement FDACS-adopted BMPs or to conduct water quality monitoring prescribed by DEP or
the applicable water management district. Under Paragraph 403.067(7)(c), F.S., the proper
implementation of FDACS-adopted, DEP-verified BMPs, in accordance with FDACS rules,
provides a presumption of compliance with state water quality standards for the pollutants
addressed by the BMPs.
FDACS Role in BMP Implementation and Follow-up
When DEP adopts a BMAP that includes agriculture, it is the agricultural landowner's
responsibility to enroll in the FDACS BMP Program and implement all applicable FDACS-
adopted BMPs to help achieve load reductions. To date, the FDACS OAWP has adopted BMP
manuals by rule' for cow/calf, citrus, vegetable and agronomic crops, nurseries, equine, sod,
dairy, poultry, and specialty fruit and nut operations. All OAWP BMP manuals are periodically
revised, updated, and subsequently reviewed and preliminarily verified by DEP before
readoption. OAWP intends to update BMP manuals every five years.
To enroll in the FDACS BMP Program, landowners must meet with an OAWP representative to
determine the BMPs that are applicable to their operation. The landowner must submit an NOI to
an OAWP representative to implement the BMPs on the checklist from the applicable BMP
manual. Because many agricultural operations are diverse and are engaged in the production of
multiple commodities, a landowner may sign multiple NOIs for a single parcel.
FDACS is required to conduct implementation verification site visits every two years to verify
that landowners are implementing BMPs identified in their NOIs. BMP verification site visits are
conducted to verify that all BMPs are being implemented properly, to review nutrient and
irrigation management records, and to collect records FDACS is required to retain. In addition,
FDACS verifies that cost -share items are being appropriately utilized. Procedures used to verify
the implementation of agricultural BMPs are outlined in Rule 5M-1.008, F.A.C. Producers not
implementing BMPs according to the process outlined in Title 5M-1, F.A.C., are referred to DEP
for enforcement action after attempts at corrective and remedial action are exhausted.
Section 403.067, F.S., requires that, where water quality problems persist despite the proper
implementation of adopted agricultural BMPs, FDACS must reevaluate the practices, in
consultation with DEP, and modify them if necessary. Continuing water quality problems will be
detected through the monitoring component of the BMAP and other DEP, SJRWMD, and
1 https://www.fdacs.gov/Agriculture-Industry/Water/Agricultural-Best-Management-Practices
Page 151 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
SFWMD activities. If a reevaluation of the BMPs is needed, FDACS will also include
SJRWMD, SFWMD, and other partners in the process pursuant to Subsection 403.067(7), F.S.
Adopted BMAP Agricultural Land Use and Enrollment
Land use data are helpful as a starting point for estimating agricultural acreage, determining
agricultural nonpoint source loads, and developing strategies to reduce those loads in a BMAP
area, but there are inherent limitations in the available data. The time of year when land use data
are collected (through aerial photography) affects the accuracy of photo interpretation. Flights
are often scheduled during the winter months because of better weather conditions and reduced
leaf canopies. While these are favorable conditions for capturing aerial imagery, they make
photo interpretation for determining agricultural land use more difficult. Agricultural lands are
often fallow in the winter months, and this can lead to the incorrect analysis of the photo
imagery.
There is also a significant variation in the frequency with which various sources of data are
collected and compiled, and older data are less likely to capture the frequent changes that often
typify agricultural land use. In addition, it is not always apparent that an agricultural activity is
being conducted on the land. Consequently, DEP relies on local stakeholder knowledge and
coordination with FDACS to verify agricultural acreage and BMP implementation.
FDACS uses the FSAID Geodatabase to estimate agricultural acreages statewide. FSAID is
derived from water management district land use data, and is refined using county property
appraiser data, OAWP BMP enrollment data, U.S. Department of Agriculture data for
agriculture, such as the Cropland Data Layer and Census of Agriculture, FDACS Division of
Plant Industry citrus data, and water management district water use and permitting data, as well
as field verification performed by USGS, the water management districts, and GAWP. Ongoing
mapping and ground-truthing efforts of the FSAID dataset provide the best available data on the
status of agricultural lands in Florida.
In terms of NOIs, enrolled acreage fluctuates when parcels are sold, when leases end or change
hands, or when production areas downsize or production ceases, among other reasons. OAWP
BMP enrollments are delineated in GIS using county property appraiser parcels. Nonproduction
areas such as forest, roads, urban structures, and water features are often included within the
parcel boundaries. Conversely, agricultural lands in the FSAID only include areas identified as
agriculture. To estimate the agricultural acres enrolled in the BMP Program, OAWP overlays
FSAID and BMP enrollment data within GIS to calculate the acres of agricultural land in an
enrolled parcel.
To address the greatest resource concerns, OAWP utilizes a phased approach based on
commodity type and agricultural acreages, while ensuring that all entities identified as
agriculture will be notified. Table C-1 lists the agricultural acreage based on FSAID VII that is
enrolled in the CIRL BMAP area.

Table C-2 lists the agricultural acreage enrolled in the CIRL BMAP area by project zone. Table
C-3 through Table C-7 list the agricultural land use acreage enrolled in the BMP Program by
commodity. Figure C-1 shows the parcels enrolled in the BMP Program by commodity in the
CIRL BMAP area; however, compliance with Section 403.067, F.S., is based on the NOIs and
site visits described in Section 1.2.1.1.

Unenrolled Agricultural Acreage
As of July 2020, 25 % of the agricultural acres in the CIRL BMAP area are enrolled in the
FDACS BMP Program and are implementing practices designed to improve water quality.
FDACS continues to increase enrollment in all BMAPs to meet the BMAP goal of enrolling
100 % of the enrollable agricultural acres in the BMP program. To achieve that goal, land use
analyses are conducted to ensure that areas containing commercial agricultural land uses are
prioritized. Lands classified as agriculture where the ability to implement agricultural BMPs
under the BMP program is limited, such as smaller rural homesteads, receive lower priority for
enrollment.
General Considerations
Although land use data have been used as the basis for prioritizing FDACS enrollment efforts,
many land use issues not captured by these databases affect enrollment efforts. Many areas
within the CIRL BMAP boundaries experience rapid land use changes, especially at the
urban/rural boundary. Agricultural lands are regularly converted to residential, industrial,
commercial, or multiuse properties, but still appear in various databases as pasture or other rural
lands. While these lands are likely to be developed in the near future, the agricultural land use
classifications require these properties to comply with the BMP enrollment requirements.
Additionally, the counties' methods of classifying small acreages as agricultural lands can affect
the BMP enrollment process. Along with these changes, there are also large agricultural parcels
being subdivided but remaining classified as "agriculture." These rural homesteads —also called
residential agriculture, rural residential, rural estates, equine communities, ranchettes, and other
descriptive names for homes with some acreage and agricultural zoning —present a particular
challenge for FDACS. The current BMP manuals and the measures they contain target
commercial agricultural production practices and, in many cases, cannot be scaled down to
appropriately enroll activities on these smaller, noncommercial agricultural properties. The
increasing number of these smaller parcels with noncommercial agricultural activity represents a
growing component of unenrolled acreage. It will be necessary to develop a suite of options to
apply to these properties or develop a new classification that may subject these types of areas to
other requirements to ensure their nutrient loading contribution is being appropriately identified
and reduced.
Further, thousands of acres of open land, scrubland, unimproved pasture, and grazing land exist
without a readily identifiable agricultural production activity that will fit within the framework of
existing FDACS BMP manuals. Also, these types of parcels are usually controlled by many
different individuals. It will be necessary to develop a suite of options to apply to these
properties or develop a new classification that may subject these types of areas to other
requirements to ensure their nutrient loading contribution is being appropriately identified and
reduced.
Another challenging area includes those agricultural lands that are inactive or fallowi.e., lands
that, on the day the FDACS representative visits, display no enrollable agricultural activity.
Page 156 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
These lands may be part of a rotation implemented by a landowner, scheduled for development,
listed for sale, etc. The land use information FDACS receives is used to consistently improve the
classification of these areas, but policy options remain limited in scope to ensure the
implementation of practices aimed at reducing nutrient inputs from these areas.
Characterization of Unenrolled Agricultural Lands
To characterize unenrolled agricultural acres, OAWP identified FSAID VII features outside the
BMP enrollment areas and overlaid these features with property appraiser parcels within GIS.
OAWP then identified the number of parcels that encompass the unenrolled agricultural lands
and the number of agricultural acres present within the parcels. The parcel owner information,
other parcel details, and aerial imagery were used identify parcels that are unlikely to contain
agricultural activity. As previously mentioned, OAWP BMP enrollments are initially delineated
based on county property appraiser parcel data, even if the entire parcel is not in agriculture, to
allow BMPs to be tied to the specific parcels where agricultural activities are occurring. FSAID
agricultural lands are delineated based on land use features identified as agriculture and represent
a more refined analysis of those areas actually in agricultural production.
Because of differences in the spatial geometries between the OAWP BMP enrollment, FSAID,
and property appraiser parcels, when they are combined or compared, the boundaries often do
not align precisely, creating "slivers." Slivers are not enrollable because they are an artifact of the
geospatial analysis and do not represent lands with active agricultural practices. For example, a
sliver can represent the area between the boundary of a parcel and the beginning of a road, canal,
easement, etc. A sliver can also represent a small portion of an FSAID feature outside the BMP
enrollment areas that is slightly overlapped by a property appraiser parcel. Slivers are often
associated with previously enrolled agricultural operations but because of the delineation
differences, these slivers are not captured within the enrolled parcel during geoprocessing. When
characterizing unenrolled agricultural lands, slivers are excluded. Figure C-2 shows an example
of a sliver created when performing geospatial analysis.
Page 157 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
Figure C-2. GIS example of a sliver
Large areas that are identified as agricultural land use but are unlikely to have enrollable
agricultural activities include lands owned by the state (Board of Trustees of the Internal
Improvement Trust Fund) and water management districts (SJRWMD or SFWMD). It is possible
that these lands, in whole or in part, may be leased to other entities that conduct agricultural
activities, but such leasing is infrequent. If leasing occurs, the leasing entity will be required to
enroll in the BMP Program. Ongoing coordination between FDACS, DEP Division of State
Lands, SJRWMD, and SFWMD is needed to ensure that any public lands that are leased for the
purposes of agricultural activities are required to implement and enroll in the FDACS BMP
Program as a condition of the lease.

Other smaller parcels that have been identified as nonagricultural, but have features that cause
them to be identified as agricultural lands in various databases, include those lands associated
with utilities, telecommunication companies, churches, FDOT rights -of -way, and airports. The
Florida Department of Revenue (DOR) uses code numbers 70 through 98 to identify these types
of lands.
Those agricultural lands that have been identified as "fallow," "former [ag]," and "abandoned,"
as well as brushland/scrubland/open land, comprise 34 % of the total unenrolled agricultural
acres in the CIRL BMAP area. These acres are still classified as agricultural land for the
purposes of the BMAP nutrient load assessment. There are a variety of potential options to
account for these lands, such as enrollment as "temporarily inactive" operations —particularly
those that were previously enrolled and are planned to resume production. Another option may
be to note the inactive acres at the time of a field visit and perform periodic reassessment on a
cyclical basis. The possibility for DEP and FDACS to calculate nutrient reduction credits or
adjust nutrient loading rates may also provide opportunities to present more accurate estimates
and establish priorities.
Another factor considered in the prioritization of BMP enrollment is the number of agricultural
acres on the parcel. Analyzing the number of agricultural acreages on the parcel and commodity
type can give an idea of the efforts that are needed to enroll these areas in the FDACS BMP
Program and also identify the areas most in need of enrollment. Figure C-3 summarizes the
agricultural acres distributed by agricultural acreage found on each parcel.
Further analysis was done to characterize the parcels based on agricultural acreage and land use
type. For graphing purposes, land use distribution is displayed in two charts, one showing the
land use for parcels containing 50 acres of agriculture or greater (Figure C-4) and a second for
parcels containing less than 50 acres of agriculture (Figure C-5). Of the 44,847 acres of land
identified as having potential agricultural activity, grazing land comprises 48 % of this acreage.

Table C-8 lists the total acreage associated with the identified slivers and the lands that are not
likely to have enrollable agricultural activities, along with the remaining total of unenrolled
agricultural acres in the BMAP area. Figure C-6 and Figure C-7 summarize the unenrolled

Future Efforts
To address resource concerns, FDACS continues enhancing coordination with producers,
agencies, and stakeholders to increase enrollment in the BMP Program. OAWP is sending
correspondence to agricultural landowners within BMAP areas that are not currently enrolled in
the BMP Program to increase enrollment rates and verify land uses where additional focus may
be required to achieve resource protection. This effort is utilizing a phased approach and
targeting priority land uses and then using the amount of agricultural acreage for the remaining
unenrolled lands, while ensuring that all entities identified as agricultural will be notified.
Additionally, OAWP continues to coordinate with industry groups and outreach partners to
educate and inform agricultural producers about the BMP Program.
Additional Factors Related to Agricultural Lands and Measuring Progress
Legacy loading can present an additional challenge to measuring progress in many areas of
Florida with adopted BMAPs. Based on research, initial verification by DEP, and long-term
trends in water quality in the BMAP area, it is expected that current efforts, such as BMP
implementation, will continue to provide improvements in overall water quality despite the
impacts from legacy loads.
Page 170 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
While the implementation of BMPs will improve the water quality in the basin, it is not
reasonable to assume that BMP implementation alone can overcome the issues of legacy loads,
conversion to more urban environments, and the effects of intense weather events. BMP
implementation is one of several complex and integrated components in managing the water
resources of a watershed. Additional regional projects, precisely located and operated, maybe
needed to achieve the TMDLs for the CIRL Subbasin.
Collaboration between DEP, the water management districts, and other state agencies, as well as
local governments, federal partners, and agricultural producers, is critical in identifying projects
and programs, as well as locating funding opportunities to achieve allocations provided for under
this BMAP. To improve water quality while retaining the benefits that agricultural production
provides to local communities, wildlife enhancement, and the preservation of natural areas
requires a commitment from all stakeholders to implementing protective measures in a way that
maintains the viability of agricultural operations.
Recommended Updates to Land Use
BMAP loads and allocations, as well as water supply projections, are based primarily on land use
data. Maintaining the most accurate agricultural land use dataset is critical to planning and policy
decisions. Although crop changes, technology advances, and land ownership/lessee changes
related to agricultural operations create dynamic environments and difficulties in estimating
impacts from specific operations, FDACS and DEP continue to coordinate and develop ways to
improve accuracy.
DEP and OAWP recognize that land use —related issues consistently occur during BMAP
development and/or updates. One of these issues is the differentiation between what is classified
as an agricultural land use in the TMDL or BMAP model, and what is no longer an agricultural
land use by the time the BMAP is adopted or an update occurs.
OAWP has developed a methodology to identify agricultural land use changes to make
adjustments in subsequent models and reports. Using GIS, OAWP compared the SWIL model
land use with the latest FSAID land use and BMP enrollment data. OAWP identified areas
classified as agriculture by the BMAP modeled land use that do not overlap with the latest
FSAID or BMP enrollment data
OAWP reviewed the output of this overlay analysis by using county appraiser data and aerial
imagery to determine if the nonoverlapping areas were still in production. It identified 3,113
acres, classified as agriculture in the SWIL land use, that now consist of other land use types
such as residential, industrial, or commercial (see Table C-9). DEP evaluated the land use
changes identified by OAWP and apportioned the associated acres and loads to the appropriate
entities after a discussion with each entity.
Often the analyses show changes that have occurred more rapidly than any land use data can
capture, such as the transition to residential development. The land use changes are provided to
DEP as a GIS shapefile with a description of the information in the county property appraiser

database and aerial imagery reflected for the refinement of the acreage and loading allocated to
agriculture in a BMAP area.

In addition to identifying land use changes in the BMAP area modeled land use, OAWP
regularly reviews FSAID data, at times daily or weekly, as it performs other job functions. Any
edits or changes are reviewed and considered for inclusion in the next iteration of the FSAID.
Potential Site -Specific Nutrient Management Measures in Addition to BMPs
Beyond enrolling producers in the FDACS BMP Program and verifying implementation, OAWP
will also work with producers to identify a suite of agricultural projects and research agricultural
technologies that could be implemented on properties where they are deemed technically feasible
and if funding is made available. FDACS executes contracts with soil and water conservation
districts and other partners to administer cost -share funds and provide technical and
administrative support for these districts and other partners. Cost -share funding is being used to
implement higher level BMPs, innovative technologies, and regional projects to provide the next
added increment of improving and protecting water quality.
Page 172 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
Table C-10 identifies the agricultural technologies that received cost -share assistance in the
CIRL BMAP area and the associated nutrient reductions based on the 2016 Soil and Water
Engineering Technology (SWET) report. Using the nutrient reductions from the report, OAWP
developed a methodology to estimate nutrient reductions for NOIs that have received cost -share
funding. The N01 boundary, based on property appraiser parcel data, was considered the area
treated by the cost -shared agricultural technology or project. For parcels with more than one
cost -share project, OAWP identified the order of treatment to determine the reductions for the
multiple projects and created a workbook that provided the cost -share agricultural technologies
and the formulas to estimate the nutrient reductions.

Appendix D. Seagrass Analysis
Process to Conduct the Seagrass Depth Limit Compliance Evaluation
The goal of the IRL Basin TMDLs is to recover the deeper seagrass habitats. The seagrass
response is the most important factor in evaluating the success of the nutrient TMDLs. Even if
the relationship among nutrient loads and seagrass recovery is not as predicted by the regression
model, the load reduction requirements themselves will not determine TMDL success. The
assessment of success is based on whether the seagrass grows at sufficient depths.
The TMDL seagrass depth limit targets are based on a union coverage of the seagrass mapping
data from 1943, 1986, 1989, 1992, 1994, 1996, and 1999. SJRWMD created this union coverage
when it set pollutant load reduction goals for the IRL Basin. The TMDL targets are not based on
the full restoration of seagrass depths represented by this union coverage; instead, they were set
at 90 % of the full restoration estimate. These targets allow for seagrass growth almost to the
depths previously seen in the lagoon, while accounting for the fact that changes have been made
to the lagoon system that may limit seagrass growth in some areas, such as dredged areas similar
to the Intracoastal Waterway.
Compliance with the TMDL seagrass depth limit targets is assessed on a project zone scale using
the latest four consecutive data sets of seagrass mapping data. For the assessment years to be
compliant with the TMDL seagrass depth limit targets, the data must meet the requirements of a
two-step evaluation process.
The first step is a comparison of the TMDL union coverage cumulative frequency distribution
curve with the assessment years' union cumulative frequency distribution curve. The cumulative
distribution curves show what percentage of the seagrass deep edge is located at different depths.
To be compliant, at least 50 % of the assessment years' curve, including the median, must be on
or to the right of the TMDL curve.
The second step in the evaluation process is a comparison of the TMDL union coverage median
value with each assessment year's median value. To be compliant in the second step, at least
three of the four assessment year medians must be equal to or greater than the TMDL median. If
the seagrass data from the four assessment years are compliant with both steps of the test, the
project zone is achieving the TMDL depth limit target.
A series of GIS steps must be conducted to obtain the data necessary to complete the two-step
evaluation process. These steps are as follows:
• Start with the seagrass GIS shapefiles for the four latest assessment years and
edit these files to include only Categories 9113 and 9116, which represent
seagrass. Other categories in the GIS shapefiles represent algae cover, which
should not be included in this assessment. The seagrass shapefiles only
represent the location of the seagrass beds.
Page 174 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
• Use the dissolve function in GIS to create the union file of the assessment
years. This union file results in a coverage of where seagrass beds were
located during all four assessment years.
• Transform the polygons to a polyline in the assessment years' union file. This
polyline represents the edges of the seagrass beds.
• Draw a 15.8-m buffer around the seagrass polyline that is 7.9 in inside and 7.9
in outside the seagrass bed. The bathymetry layer was created by SJRWMD in
1996, and the bathymetry was measured every 15.2 in. The 15.8 in buffer
around the seagrass polyline ensures that I bathymetry point will be captured
in the GIS analysis.
• Intersect the updated bathymetry shapefile with the seagrass coverage file that
was transformed into a polyline. This intersection correlates the depth data
with the seagrass locations so that depths along the seagrass bed edge can be
determined.
• Intersect the deep edge file to each project zone (BRL A, BRL B, North A,
North B, Central A, Central SEB, and Central B).
• Use the select by location function to identify and note points within dredged
areas. The dredged areas are removed from this coverage because seagrass is
not expected to grow in areas that have been dredged.
• Identify and note points that fall below 0.3 in and above 3.5 in from the
coverage. This step is needed because seagrass growing at depths less than 0.3
in are likely not light -limited, and seagrass are not expected to grow at depths
greater than 3.5 in.
• Identify and note points from the intersections of holes or bare areas, which do
not represent the deep edge of the seagrass bed.
• These steps are also followed separately for each assessment year so that the
median value can be calculated.
The final points that represent the seagrass deep edge boundary for the assessment years' union
coverage are then exported from GIS into Excel to conduct the two-step evaluation. The depth
points are sorted from highest to lowest, and the count of the number of points at each depth is
determined. The cumulative count is determined by taking the count for the shallowest depth and
adding it to the count for the next shallowest point until the counts for all the depths are added
together to yield the total number of depth points. The cumulative count at each depth is divided
by the total points to determine the percentage of the seagrass points at each depth. These points
are then plotted as a curve on a graph for comparison with the TMDL cumulative distribution
curve. For the Step 2 evaluation, the median depth point is calculated for each assessment year
using Excel. These medians are then compared with the TMDL median to determine compliance.

The maps in Figure D-1 through Figure D-3 include the locations of ground truthing conducted
before and during aerial surveys. Additionally, the transect locations where SJRWMD conducts
seasonal monitoring are shown. For more information on how SJRWMD and partners conduct
seagrass surveys, SJRWMD's SOP is referenced in Chapter 5.

Appendix E. WCDs and Other Special Districts
In the 2013 BMAP, WCDs and other special districts were assigned quantitative (numeric)
allocations, which included all agricultural and urban lands within their jurisdictional boundaries
that were not part of an MS4. During the development of the 2013 BMAP, there were concerns
with this approach, because FDACS is the only entity that can enroll agricultural producers in
BMPs, but the WCDs were held responsible for reducing loading from the agricultural areas. In
addition, the urban lands within the districts were permitted by the city or county and not under
the district's control.
Therefore, this 2020 BMAP assigns qualitative (activity -based) allocations to the special districts
for the canals and rights -of -way, as the districts have control over these portions of their
jurisdictions. The districts are required to implement specific canal and right-of-way BMPs to be
compliant with the BMAP. The BMPs for each special district are based on the activities and
land uses in the district, and reporting on those BMPs is due annually. The included BMP plans
were prepared and submitted by each individual WCD and reviewed by DEP.
FELLSMERE WATER CONTROL DISTRICT (FWCD)
The FWCD (formerly known as the Fellsmere Drainage District) was created April 8, 1919,
under the General Drainage Laws of the State of Florida, by a Circuit Court proceeding (St.
Lucie County, Case No. RED 533) and currently operates under Chapter 298 of the Florida
Statutes, and amendments thereto, as an Independent Single Purpose Special District. The district
was created and is responsible for the drainage, flood protection, and control with respect to
drainage in times of excess water within its geographical boundaries. The FWCD does not
generate any nutrient loading. The district receives the runoff from the lands within the gravity
drainage portion of the overall district and conveys the flow to the Fellsmere Main Canal
discharge point. The district map is shown in Figure E-1.
The original overall district watershed included 50,000 acres of land primarily used for
agriculture. The system includes east -west sublateral ditches approximately one -quarter mile on
center. Because of the naturally occurring 10 mile ridge (Interstate 95) east of the district; the
land generally slopes from east to west. The one -quarter mile ditches flow west into the lateral
canals. The lateral canals flow north to the Fellsmere Main Canal.
The Fellsmere Main Canal is located along the north boundary of Indian River County and is
graded to drain east through the 10-mile ridge and into the west prong of the St. Sebastian River.
A plug in the Fellsmere Main Canal west of Lateral U, and internal control structures in Lateral
U near Sublateral Ditch 20 and in Park Lateral near Sublateral Ditch 24, separates the gravity
drained watershed and the pumped drained watershed.
With the acquisition of lands and development of the Upper St. Johns River Basin project by
SJRWMD, the watershed basin of the original Fellsmere Water Control District has been
reduced to 34,000 acres. A majority of the remaining area within the Fellsmere Water Control

District is owned by Fellsmere Joint Ventures (FJV) and is pumped, or partially pumped, into
portions of the Upper St. Johns River Basin.
Page 181 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
The remaining gravity drained portion of the FWCD is drained by two lateral canals (Park
Lateral and Lateral "U"). Generally, Park Lateral drains all the land within FWCD lying east of
Park Lateral (including "The Original Town of Fellsmere") and north of Sub -lateral PL-24,
containing approximately 14.0 square miles. Park Lateral also partially drains the former "Berry
Groves" parcel (now owned by FJV), containing approximately 6 square miles, that is pumped
south into the Blue Cypress Water Management Area (BCWMA), during heavy rainfall events.
Lateral "U" Canal gravity drains all the land west of Park Lateral Canal and north of Sublateral
U-20, containing approximately 8.4 square miles, and partially drains a portion of its southern
basin (between Sublateral U-20 and U-28), containing approximately 2.5 square miles. This area
is pumped south into BCWMA during heavy storm events.
The remaining nongravity-drained portions of the district are drained through pump stations, all
owned and operated by FJV (SunAg, Inc.), into water management areas of the Upper St. Johns
River Basin.
The FJV agricultural land that gravity drains to the CIRL is enrolled and is subject to the BMP
Program managed by FDACS.
FWCD developed the Permit Information and Criteria Manual for Use of or Connection to
Works of the District, the purpose of which is to provide information describing the criteria and
permitting requirements relating to the utilization of, and connection to, the works of the FWCD.
A copy of the manual and other information associated with FWCD can be found on the district's
website: http://www.fellsmerewatercontroldistrict.com/permits.html.
FWCD proposes that the listed BMPs will be implemented and reported as active -based
strategies. A specific allocation or nutrient reduction target will not be established. Rather, the
FWCD's activities will serve to assist in the control of nutrients as part of the efforts described in
the BMAP. Implementation of the BMPs shall provide compliance with the BMAP.
In selecting the BMPs, in coordination with DEP, the function, operation, and budget of FWCD
has been considered. Each year, during the annual report information collection period, FWCD
will confirm that these activities continue in its canals and rights -of -way. Each BMP includes a
description and the required records.

FORT PIERCE FARMS WATER CONTROL DISTRICT (FPFWCD)
The FPFWCD was originally created in 1919 under the provisions of Chapter 298, F.S.,
commonly referred to as the General Drainage Law of Florida. The FPFWCD is located in St.
Lucie County, and current FPFWCD boundaries encompass roughly 13,000 acres. The FPFWCD
is responsible for drainage, flood control and protection, water managemen and the reclamation
of lands within FPFWCD boundaries. The FPFWCD owns, operates, and maintains works for
water management and regulates their use by others. The water management system generally
includes a network of approximately 50 miles of canals, and associated pumps and water control
structures. The Phillip C. Gates structure is the main water control structure located within Canal
No. 1 that serves to regulate stormwater discharges into the Indian River Lagoon from FPFWCD.
The original construction consisted of four 8 foot (ft) by 16 ft radial gates that opened from the
bottom at elevation 6 ft National Geodetic Vertical Datum (NGVD). In 2018, FPFWCD
completed a retrofit project in which the two outer gates were split at elevation 10 ft-NGVD and
the two center gates were split at elevation 8 ft-NGVD. The retrofitted structure reduces
sediment deposits downstream of the structure. An aerial map of the FPFWCD boundary (thick

white line) and drainage canals is shown in Figure E-2. A more detailed map identifying the
canal numbers and associated rights of way is shown in Figure E-3.
Figure E-2. Map of the FPFWMD
A map generally depicting the agricultural producers enrolled within the FPFWCD is on file with
FDACS. Significant stormwater entering the FPFWCD canals is subject to the FDACS program.
Additionally, stormwater entering the FPFWCD canals are subject to criteria imposed by other
local, state, and federal agencies —including, but not limited to, the City of Fort Pierce, St. Lucie
County, SFWMD, DEP, and U.S. Army Corps of Engineers (USACE).
The FPFWCD developed the Permit Information and Criteria Manual for Use of or Connection
to Works of the District, the purpose of which is to provide information describing the criteria
and permitting requirements relating to the utilization of, and connection to, the works of the
FPFWCD. A copy of the manual and other information associated with FPFWCD can be found
on the district's website: httn://fafwcd.or2/.
The FPFWCD proposes that the listed BMPs will be implemented and reported as active -based
strategies. A specific allocation or nutrient reduction target will not be established. Rather, the
Page 185 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
FPFWCD's activities will assist in the control of nutrients as part of the efforts described in the
BMAP. The implementation of the BMPs shall provide compliance with the BMAP.
In selecting the BMPs, in coordination with DEP, the function, operation, and budget of the
FPFWCD has been considered, and these listed BMPs should not be considered as cost-effective,
technically practical, or applicable to any other water control district within the BMAP area.
Each BMP includes a description and the required records.
1. Aquatic Vegetation Control
Description: Perform harvest aquatic vegetation within the canals using mechanical processes to
the extent practicable to reduce the need for herbicide treatment. Vegetation removal from the
canals shall be placed in a manner as to limit the possibility of the material reentering the canal.
Use of herbicide treatments shall be used at locations where canal bank stabilization measures,
such as rock riprap, have been installed.
Report: Disposal of material outside of the district's rights -of -way is cost prohibitive at this time
and will only be performed when deemed necessary by the district. The FPFWCD shall report
herbicide treatment locations and provide a justification for each location.
Z Canal Buffer
Description: Create a canal buffer or filter strip to help reduce loading from stormwater runoff to
the canals. Maintenance activities consisting of mowing the canal banks shall be limited to the
area outside a minimum distance of 10 feet from the canal top -of -bank. Mowing and
maintenance activities shall be done in such a way to prevent grass clippings from entering the
canals, where they can decompose and add nutrients.
Report: Width and locations (or percentage of canal banks that include a buffer strip) of
vegetated buffer strip. Type and location of any alternative methods of canal buffer or filter
strips.

INDIANRNER FARMS WATER CONTROL DISTRICT (IRFWCD)
The original Plan of Reclamation of the IRFWCD, formerly known as the Indian River Farms
Drainage District, was initially adopted and approved by the Board of Supervisors of the Indian
River Farms Drainage District on March 4, 1920.
At that point in time, the Indian River Farms Drainage District was located in St. Lucie County
(Indian River County was created in June 1925), and the order approving the Report of
Commissioners was approved by the Fifteenth Judicial Circuit in St. Lucie County on August
18, 1921, and recorded in Chancery Order Book 2, Page 493, Public Records of St. Lucie
County.
The original Plan of Reclamation (now an integral part of the "Water Control Plan") has long
been completed, and the IRFWCD now functions as an operations and maintenance entity of
the Works of Improvements therein.
In the early to mid 1980s, the IRFWCD approved and undertook a project of evaluation and
updating of the original Works of Improvements of the District. This study resulted in the
creation of a computer model of the District's facilities and various revised recommendations in
the operations of the district, including the two -inches -per -day volume discharge limitation.
The district map is shown in Figure E-4.
The IRFWCD contains approximately 50,000 gross acres lying within portions of Township 32
and 33 South, Range 39 East and Township 33 South, Range 38 East, and a small portion of
Township 33 South, Range 40 East in Indian River County.
The IRFWCD contains the western portion of the City of Vero Beach (primarily west of the
ancient coastal dune/ridge located along the Florida East Coast Railroad alignment) and the
remainder of the district lies within the unincorporated area of Indian River County.
The 1913 Plat of Indian River Farms Subdivision was originally subdivided into primarily 40-
acre, more or less, tracts and developed for agricultural use. With the growth of population and
development in the IRFWCD, the gradual conversion of agricultural lands to urbanization has
occurred concentrically around the City of Vero Beach (westward from the coast) and along
major corridors such as State Road 60, 27th Avenue, 43rd Avenue, 58th Avenue, and Oslo
Road (9th Street, S.W.)
The initial canal system was designed and constructed by the Indian River Farms Company
in the 1912 to 1917 era, and contained only the Main Outfall Canal.
In early 1919, steps were taken to reorganize the former "district" under the General Drainage
Laws of Florida. This new district was modified and reformed into the Indian River Farms
Drainage District in May of 1919 and currently operates under Chapter 298, F.A.. This plan
Page 189 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
expanded the limits of the original project, adding the north and south relief canals and
interconnecting lateral and sublateral canals.
Page 190 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
This system was designed and constructed only as a gravity flow drainage district comprising
many sublateral canals spaced one-half mile apart (generally along section and one -quarter
section lines in an east -west alignment). These sublateral canals discharge into lateral canals
(generally running in a north -south direction which, in turn, discharge into three major relief
canals) that ultimately outfall into the IRL.
The initial design and construction of the system contained only one structure in the Main
Canal. This structure is a drop spillway structure and provides a grade transition from 9.0 ft
above sea level upstream to 0.00 ft downstream to prevent erosion and sloughing in the Main
Relief Canal.
In the mid- 195Os, radial gate water control structures were constructed in the three outfall
canals to (1) reduce irrigation requirements, (2) conserve water, and (3) provide a limited
source of supplemental irrigation water.
A salinity control weir structure was constructed in the Main Canal downstream of the drop
spillway structure in 1962 to protect the City of Vero Beach wellfield from saltwater intrusion,
and to provide irrigation water for the Vero Beach Country Club golf course.
In 1963, a fourth radial gate water control structure was added in Lateral "C" Canal (74th
Avenue) south of 8th Street to reduce irrigation requirements and provide a limited source of
irrigation for landowners in the southwest portion of the district.
The operation of the radial gate structures in the district relate directly to the duration and
intensity of storm events and the antecedent rainfall conditions. The gates are kept closed a
majority of the time, maintaining a minimum elevation of 15.5 ft, more or less, above sea level
upstream of the 3 radial gates located in the 3 outfall canals, and 18.5 ft, more or less, above
sea level upstream of the Lateral "C" structure.
These gates are opened, or partially opened, following storm events that create flooding
conditions in the respective upstream pool elevations of the structures. The gates are opened
only for a few hours to relieve flooding conditions in the affected areas. Following major storm
events and complete ground saturation, the gates may be left open for a few days to provide
groundwater draw down.
The IRFWCD is isolated from surrounding drainage by a levee (elevation 28.5 ft, more or less,
above sea level, 6 ft to 8 ft top width and 1.5 ft to 1 ft side slope) along its north, west, and
south boundary and by a coastal/dune ridge along its eastern boundary. It is further protected by
adjoining water control districts along its north, west and southern boundaries, and serves no
area outside its geographic area.
The IRFWCD proposes that the listed BMPs will be implemented and reported as active -based
strategies. A specific allocation or nutrient reduction target will not be established. Rather, the
IRFWCD's activities will assist in the control of nutrients as part of the efforts described in the
BMAP. The implementation of the BMPs shall provide compliance with the BMAP.
Page 192 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
In selecting the BMPs, in coordination with DEP, the function, operation and budget of the
IRFWCD has been considered. Each year, during the annual report information collection
period, the IRFWCD will confirm that these activities continue in their canals and rights -of -
way. Each BMP includes a description and the required records.
Indian River Farms Water Control District BMPs
Harvest aquatic vegetation in the canals using mechanical processes along with some
necessary herbicide treatment. Vegetation removed from the canals must be disposed of in
a location where the material will not be able to reenter the canal. Vegetation harvesting
should consider the DEP guidelines in Removal of Aquatic Vegetation for Nutrient Credits
in the Indian River Lagoon (IRL) Basin (September 2012).
o Report: Dates when harvesting occurred and disposal location. Report any
herbicide treatments and justification for nonmechanical removal of
vegetation.
2. For all new change of land use development projects, exempting single-family residences,
an IRFWCD connection permit will require the compliance with the stormwater discharge
limitation policy of 2 inches/24 hours for a 25-year-24-hour storm event. This limitation
applies to any 24-hour period (hour 10-34, hour 14-38, etc.) during the 72-hours starting at
time 0 of a 25-year, 24-hour storm event.
o Report: The IRFWCD model results will provide the developer's engineer
with a boundary condition at the connection point to the IRFWCD system.
The boundary condition will include a time stage summary for hours 0 — hour
72 of the 24-hour-25-year event. A list of projects permitted over the year
will be provided.
3. Provide public education to residents of the district that fosters an understanding of the
necessity to reduce nutrient impacts to surface waters.
o Report: Provide a link or brief summary of the information
regarding the encouraged use of BMPs throughout the district.
4. Assist FDACS, where needed, with identifying and contacting producers within the
district boundaries for purposes of participating in the relevant FDACS BMP programs.
o Report: Number of landowners contacted to assist FDACS, and the names
of landowners.

MELBOZURNE-TILLMAN WATER CONTROL DISTRICT (MTWCD)
The Melbourne -Tillman Water Control District (MTWCD) is a dependent special district
authorized by the Florida Legislature under Chapter 2001-336, Laws of Florida, as amended by
Chapters 2003-334 and 2010-253, respectively, for the purpose of constructing, reconstructing,
and repairing, maintaining, and operating a surface water management system.
It was initially authorized as an independent district in 1922 for land reclamation for agricultural
development and operating under Chapter 298, F.S.. It was reorganized as a dependent district in
1986 under Chapter 86-418, Laws of Florida, and codified in the 2001 legislation.
The Board of Directors has the power to establish a water management system to prevent
damage from flooding, soil erosion, and excessive drainage; to promote the conservation,
development, and proper utilization of surface and ground water; to preserve natural resources,
fish, and wildlife; to maintain water quality; and to preserve and protect natural systems within
and surrounding the district. The Board may authorize the cleaning, straightening, widening, or
the change of course or flow, and alter or deepen any canal, ditch, drain, watercourse, or natural
stream within the district boundaries. The building and construction of other works and
improvements to preserve and maintain the works of the district are also authorized.
The MTWCD encompasses portions of unincorporated Brevard County, City of West
Melbourne, City of Melbourne, City of Palm Bay, Town of Malabar, and Town of Grant-
Valkaria. MTWCD is responsible for maintaining a primary network of canals within the district
boundary. Various parcels have privately owned outfalls to the canals, with runoff from the
remaining lands collected by the various governmental agencies delivering the runoff to the
canals.
A map of the MTWCD canals and boundary is shown in Figure E-5. The district owns and
maintains over 2,300 acres of canal rights -of -way in 163 miles of canals; 50 % has a right-of-
way width greater than 100 ft, and 8 % has a right-of-way width greater than 250 feet. The
district boundary covers 102 square miles.
The MTWCD proposes that the listed BMPs will be implemented and reported as activity -based
strategies. A specific allocation or nutrient reduction target will not be established. The
MTWCD's activities will assist in the control of nutrients as part of the efforts described in the
IRL BMAP. Implementation of the BMPs shall provide compliance with the BMAP.
The BMPs, in coordination with DEP, are selected with the function, operation, and budget of
the MTWCD in consideration, and the BMPs are not intended to be cost-effective, technically
practical, or applicable to any other water control district within the BMAP area. Each BMP
includes a description and the required record keeping.
It is recognized that the configuration of the canals and rights -of -way are limiting factors to the
performance of certain BMP. An annual report confirming the activities identified are reported to
DEP, with detailed records kept at the MTWCD office.

SEBASTIANRIVER IMPROVEMENT DISTRICT (SRID)
The SRID is a "Chapter 189 — Improvement District" that was originally organized as a "Chapter
298 Drainage District." Reorganized under Chapter 189, the district is now known as SRID;
however, the district still operates as a single -purpose drainage district.
The Sebastian River Water Control District was initially created by Decree of Incorporation
entered by the Circuit Court in 1927 and included approximately 50,000 acres. Following the
1929 Depression, the Plan of Reclamation was scaled back in 1939 to the approximate 11,000
acres of the present day SRID.
The SRID system was designed and constructed as a gravity flow drainage district comprising
sublateral canals spaced one-half mile apart in an east to west alignment. These sublateral canals
discharge into Lateral Canals C and L which are constructed in a north -south alignment and
drain to the north, and discharge into the south fork of the St. Sebastian River that ultimately
outfalls into the IRL.
In the late 1950s, radial gate water control structures were constructed in the two outfall canals to
(1) reduce irrigation requirements, (2) conserve water, and (3) provide a limited source of
supplemental irrigation water.
In 2009, the district undertook a project to create a Survey Inventory of Existing Infrastructure
and prepared a report called, "Stormwater Modeling to Evaluate the Works of Improvements of
the District." This study resulted in the creation of a computer model of the district's facilities
and various revised recommendations for the operations of the district, including the 2-inches-
per-day volume discharge limitation.
The SRID contains a few residential areas, churches, a golf course, and schools but remains
mostly in agricultural lands that lie within the unincorporated area of Indian River County.
The operation of the radial gate control structures within the district relate directly to the duration
and intensity of storm events and the antecedent rainfall conditions. The gates are kept closed the
majority of the time, maintaining a minimum elevation of 14.5 and 12.5 ft NAVD, more or less,
upstream of the radial gates located in Lateral Canals C and L, respectively.
The district map is shown in Figure E-6.
These control gates are opened, or partially opened, following storm events that create flooding
conditions in the respective upstream pool elevations of the structures. The gates are opened only
for a few hours to relieve flooding conditions in the affected areas. Following major storm events
and complete ground saturation, the gates may be left open for a few days to provide
groundwater drawdown.
Page 197 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
The SRID is isolated from surrounding drainage to the west by a levee. The south and east
boundaries are common boundaries with IRFWCD, and each district has levees and boundary
canals to manage water within their limits. The north boundary of SRID is isolated with smaller
dikes, since the land slopes off the Sebastian River to the north.
The SRID proposes that the listed BMPs will be implemented and reported as active -based
strategies. A specific allocation or nutrient reduction target will not be established. Rather, the
SRID's activities will assist in the control of nutrients as part of the efforts described in the
BMAP. The implementation of the BMPs shall provide compliance with the BMAP.
In selecting the BMPs, in coordination with DEP, the function, operation, and budget of the
SRID has been considered. Each year, during the annual report information collection period, the
SRID will confirm that these activities continue in its canals and rights -of -way. Each BMP
includes a description and the required records.

VERO LAKES WATER CONTROL DISTRICT
The Vero Lakes Water Control District (VLWCD) is a Chapter 298 District originally
established as Vero Lakes Drainage by Decree of Incorporation of the Ninth Judicial Circuit in
Indian River County, dated June 17, 1965. The VLWCD encompasses approximately 6,250 acres
located entirely in north Indian River County, Florida. In general, the district is bisected by I-95,
with portions of the district lying both east and west of I-95. The entire district is located south of
SR 512. See Figure E-7 to better locate the boundaries of the district (shown in blue).
The entire district is undeveloped, raw land with a single landowner. The entire district is in
agriculture for the purpose of cattle raising. The stormwater runoff is collected in various low
wetland areas. A primary ditch carries some stormwater from the southwest to the northeast
section of the district that lies west of I-95. There are culverts under I-95 that allow some runoff
that does not percolate back into the soil to flow east towards the eastern edge of the district.
Page 200 of 202
Central Indian River Lagoon Basin Management Action Plan, February 2021
Eventually, water that does not percolate back into the soil flows east to Lateral D. This does not
increase the nutrient load in the runoff. The natural, undeveloped land acts as a filter for any
runoff that makes its way east to Lateral D.
