WORK AUTHORIZATION N0.3
TWIN DITCHES STORMWATER RETROFIT PROJECT
SCOPE OF SERVICES
PURPOSE
This is an attachment to the Engineering Services Agreement for the City of Sebastian
Continuing Services agreement dated Apri12, 2004, between the City of Sebastian (CITY) and
the firm of Camp Dresser & McKee Inc. (CDM) and made a part thereof. The purpose of this
Exhibit is to specify the required services of CDM to conduct the portions of Master stormwater
Management Plan (MSMP) Implementation requested by the CITY.
BACKGROUND
Recently, the CITY completed an updating of their MSMP. This revision of the MSMP included
hydraulic modeling of the primary canal system, water quality modeling of the portion of the
City tributary to the South Fork of the Sebastian River. The MSMP made recommendations to
reduce flooding due to a lack of storage and conveyance in the primary system. The MSMP also
made recommendations to reduce mass loading of nutrients and total suspended solids to the
South Prong of the Sebastian River.
The CITY and CDM met with the St. Johns River Water Management District (SJRWMD) in a
MSMP review meeting and discussed the potential rehabilitation and retrofit of the City's
stormwater system to improve water quality treatment and facilitate maintenance.
The proposed improvements to the Twin Ditches are discussed in this scope of services. The
project area and select features are shown on Figure 1.
There are economic advantages to designing and permitting work authorizations 1, 2 and 3 as a
single project and the associated budgets are based upon this assumption.
The converted primary canals will provide water quality treatment for the City's stormwater
runoff both in the existing conditions and potentially provide water quality treatment for areas
within the City that will have their Swale collection system converted to a Miami curb system.
The components of the project are described as follows:
Twin Ditches is the primary canal that drains a portion of the Airport as well as the area
adjacent to Main Street. Currently, the cross section of this canal consists of two channels with a
significant amount of material between the channels.
The Twin Ditches extends approximately 4000 feet, from Airport Drive to its ultimate outfall
immediately to the northwest of the intersection of Main Street and Wimbrow Drive. The canal
has an approximate top width of 60 to 75 feet, which includes the center portion, which is
approximately 20 feet wide. Upstream of Airport Drive the twin ditches separate, the more
northern of the ditches makes a right angle turn to the northwest into the airport proper and
mh7569 WA 3.doc
provides drainage for a portion of the airport. The more southern ditch continues to run parallel
to Main Street in a northeastern direction eventually making a right angle turn to the southeast
crossing Main Street. Flow enters the canal along its length either through overland flow, from
northern side or via open or closed side yard drainage features.
The proposed improvement along the Twin Ditches will include enlargement of the existing
cross section (i.e. removing the center berm), protection of the southern slope of the channel to
improve stability, replacement of the culverts under Airport Drive and the construction of a
water control structure at the downstream end of this canal.
SCOPE OF SERVICES
The following tasks define the Scope of Services for the implementation of the stormwater
improvements recommended for the Phase 1 primary stormwater management systems
(PSMS). The tasks include the following services: survey, geotechnical, stormwater evaluation
and modeling, design, permitting, bidding services, and public presentation to be completed by
CDM.
Phase 2 services for general and resident construction services will be determined at a later date.
CDM shall complete the following tasks under Phase 1:
TASK 1-SURVEY SERVICES
CDM, as part of this scope, will collect the topographic information to design the proposed
improvements as listed in BACKGROUND above. A survey of the Twin Ditches as well as a
limited survey of the tributary channels and culverts will be completed for hydraulic evaluation
purposes. The survey services will provide the necessary support to define the extent of the
existing drainage easements.
The survey will establish a State Plane Coordinate (NAD 83) baseline for horizontal and vertical
control, provide cross sections, flag wetlands, locate soil borings, potholes to locate utilities
conflicts (up to 10), determine invert/ top elevations of all utilities within the project area and
determine inverts and geometry of selected culverts. The survey services will also include
existing right-of-ways and easements. The survey services will be provided by a subcontracting
surveyor and are divided into three sub-tasks, as follows:
Subtask 1.1 -Overall Surveying Services
The following survey work is included in this sub-task:
Research: acquire horizontal and vertical control near the project, right of way map for the
Twin Ditches and existing easements and right-of-ways.
^ Control: Establish State Plane Coordinate control (Horizontal NAD 83 and Vertical
NGVD29) as monuments at the project area for at least eight (8) points. Including control in
the vicinity of Airport Drive and Main Street.
^ Wetland jurisdictional location: Locate and map the wetland flagging placed by CDM. Up to
45 flags are estimated for budget purposes.
mh1569 WA 3.doc
TASK 2 - GEOTECHNICAL SERVICES
CDM shall conduct asub-surface soil investigation for the project design. CDM will retain a
qualified geotechnical investigation subcontractor to conduct test borings and geotechnical
laboratory testing. The geotechnical investigation will provide an overview of conditions in the
project area to help define the geotechnical limitations of the proposed improvements. The sub-
surface soil investigation shall include soil borings and soil characterization along the central
berm and southern face of the canal. Estimation of the seasonal high water table will also be
required as part of the sub-surface soil investigation.
The geotechnical services that will be performed in the project area include conducting test
borings and geotechnical laboratory analyses, and providing geotechnical and design
recommendations to support the stormwater improvements and other elements of the project.
The results of the geotechnical analyses will be documented in a report containing the following
subtasks:
Subtask 2.1 -Data Collection
This task includes the collection of the geotechnical information to be used in subsequent
subtasks.
^ Soil borings and characterization of center berm and southern slope of Twin Ditches starting
at Airport Drive every 250 feet.
Subtask 2.2 -Report
This task includes the reporting of the findings determined from the data collection and will
include:
^ Presentation of the field and laboratory test procedures used.
^ Description of subsurface conditions, including subsurface profiles, and estimated
geotechnical engineering properties to design modification of existing channel cross
sections.
^ Recommendations for the required site preparation and earthwork construction.
Subtask 2.3 -Seawall Design
This task will include design of proposed seawalls and will include:
^ Conceptual design of seawalls including general discussion of conditions of existing
seawalls
^ Final design of seawalls including value engineering discussion of potential materials which
could be used.
TASK 3 -HYDROLOGIC & HYDRAULIC EVALUATION
CDM will use the ICPR (Version 3.02) hydrologic/hydraulic model developed for the City of
Sebastian s Master stormwater Management Plan (CDM, 2004) and modify the model (based on
mhi569 WA 3.doc
latest available survey) to develop the recommended alternative. The evaluation will consist of
the following subtasks:
Subtask 3.1 - Refinement of Hydrologic Representation
The area tributary to these two canals is approximately 800 acres and consists of 19 hydrological
units in the existing storrnwater model. In order to provide a more refined representation it is
proposed to subdivide up to ten existing hydrologic units. In addition to the refinement of the
hydrologic units, the curve number and time of concentration will be recalculated.
Subtask 3.2 - Refinement of Hydraulic Representation
In the ICPR model, the existing representation of Collier Canal consists of 14 links and the Twin
Ditches consists of 5 links. These links will be updated with the obtained survey. Additionally,
cross sections for those channels upstream of the Twin Ditch will be obtained and these links
will also be refined. Also included in the survey scope are a number of culverts, which maybe
included in the model. These culverts include those that penetrate the seawalls as well as
culverts providing conveyance to Collier Canal and the Twin Ditches.
S:cbtask 3.3 -Simulation of Existing Conditions
CDM will simulate the mean annua1,10-year, 25-year and 100-year design storm events of a 24-
hour duration. The evaluation will consider runoff volumes, peak stages, flows and velocities
within the project. CDM will also quantify the level of water quality treatment currently being
provided in this portion of the CITY.
Subtask 3.4 -Simulation of Proposed Conditions
CDM will modify the existing conditions model to represent the proposed modifications to both
Collier Canal and the Twin Ditches. These modifications will include, modifications to the cross
section based upon proposed dredging and modification/construction of a control structure
associated with the outfall of the canals. CDM will also quantify the level of water quality
treatment as equivalent volume that will be provided by the proposed modifications in this
portion of the CITY. The modifications will be iterative and based upon the conceptual design
as defined in Task 5 below.
Subtask 3.5 -Documentation of Model Modifications
CDM will document the results of the modification of the existing and proposed condition
models. This documentation will include discussion of curve number and time of concentration
calculations, refinement of hydrologic representation, refinement of hydraulic representation,
comparison of peak stages and flows and a discussion of the proposed conditions.
This documentation will provide the basis of the permit application package to be submitted to
the SJRWMD as described in Task 6 below.
TASK 4 -ENGINEERING ANALYSIS AND DESIGN
CDM will prepare construction plans for the recommended improvement. CDM will prepare
24-inch x 36-inch plans (1-inch = 50 feet). The Canal and ditch work will be shown on plan and -
profile drawings. The seawall will also be shown on the plan and profile drawings for the
Collier Canal. CDM will work with CITY staff to accommodate the proposed improvements
mh1569 WA 3.doc
within the limited space to the extent possible without impacting adjacent properties and/or
identified utilities.
The proposed improvements, as outlined above, consist of the dredging of the existing primary
canals, replacing seawalls, armoring channel side slopes, and construction of a water control
structure to provide increased residence time for water quality improvement of the stormwater
runoff.
Subtask 4.1 -Conceptual Design
CDM will prepare a conceptual design for the project for review by the CITY. The conceptual
design will be developed in conjunction with the Hydraulic Evaluation in Task 3. This will be
done to determine the most cost effective design, which will meet the water quality objectives of
this project. The conceptual design will consist of typical layouts, typical cross sections and
typical details that will be used iri the final design. The conceptual design, (30 percent complete)
will also include a conceptual cost estimate of the improvements required for the entire system
so that if phasing of the capital expenditures is required it can be planned.
Subtask 4.2 -Contract Drawings
CDM will prepare plans for the construction of the proposed modifications for the Twin
Ditches.
CDM will submit 30, 60 and 90 percent plans to the CITY for review. This task includes two (2)
review meetings with CTTY staff at the 50 and 90 percent design milestones. Each design
milestone will include an opinion of the construction cost of the proposed improvements (Sub-
Task 5.4 below).
After the 30 percent design milestone has been reviewed and approved by the CITY, CDM will
incorporate comments and continue preparation of design documents for the 60 percent design
plans. At the 90 percent completion stage, CDM will provide a constructability review of any
proposed improvements and update the hydraulic modeling as necessary.
The construction plans will consist of plan sheets listed in Table 1 below and include the
performance of specific work and preparation of details and documents as follows:
^ Plan and Profile drawings at 1-inch = 50 feet of improvements
^ Geotechnical Data
^ Access road details (if necessary)
