Draft Sections II -VI of the Plan —ACTION ITEM i. Non -Chemical Methods by asset classification Submitted for Committee Member Approval If Aqenda Item Requires Expenditure of Funds: Total Cost: n/a Attachments: Draft Sections II-V of the IPM Plan INTEGRATED PEST MANAGEMENT PLAN II. STRUCTURES Overview Stormwater assets classified as "structures" includes all dams, weirs, spillways, catch basins, baffle boxes, culvert pipes, inlets, outlets, and outfalls. There are over 100 such structures across the stormwater system. These assets have a virtually zero tolerance for pests, as they must stay clear of vegetation and debris at all times in order to function. Do Nothing Option The overgrowth of aquatic vegetation around and within these structures can greatly impede the flow of water, contributing to flooding issues. Also, the vegetation can inhibit their operation and cause costly damage to structures. Therefore, the tolerance threshold for pest activity, before action is taken is considered the very low for these assets. Non -Chemical Methods In order to eradicate vegetation, the following cultural and mechanical methods will be conducted routinely as part of standard proactive maintenance procedures within the City's stormwater system: • Vacuum Removal. A vacuum truck is utilized to remove all accumulated sediments and vegetative debris from catch basins and baffle boxes regularly. The amount of debris removed is recorded. • Manual Removal. When safe and practicable, vegetation will be removed by hand from structures as part of routine inspections. CITY OF SEBASTIAN PAGE 10 INTEGRATED PEST MANAGEMENT PLAN III. CANALS Overview Stormwater assets classified as "canals" include the entire interconnected system of wide, mostly sea walled waterways. Altogether, the City maintains over 9 miles of canals and seawalls. It is acknowledged that aquatic vegetation provides an important ecological function in the canals. However, the City must be careful that the storage and flow capacity of these important waterways is protected. Do Nothing Option The overgrowth of aquatic vegetation within the canal system can greatly impede the flow of water, crucial for flood control throughout the City. The canals are also frequently utilized for kayaking and fishing. These recreational opportunities are lost when dense vegetation blocks navigation and affects the habitat quality by altering the water's chemistry and decreasing light penetration. Finally, and most importantly, the canal system has multiple direct outfalls to the San Sebastian River (SSR). Any vegetation that is not properly maintained in the canal system is easily introduced into this State protected freshwater system. For this reason, Florida Statute 369.22 (Appendix X) requires that all public and private water owners enact a "maintenance program" for aquatic vegetation. Therefore, the tolerance threshold for vegetation growth, before action is taken is considered moderate for these assets. Non -Chemical Methods In order to control vegetation, the following cultural and mechanical methods will be conducted routinely as part of standard proactive maintenance procedures within the City's stormwater system: • Dredging. When areas of the canal system are at their lowest storage, the City can access the canal bottoms with equipment to mechanically remove the vegetation and accumulated sediments. • Mechanical Removal by Contractor. During periods where invasive vegetation has spread too extensively at a location to be brought back under control by routine methods, a contractor may be hired with the equipment to cut and remove the vegetation by boat. • Sediment and Erosion Control at Development Sites. In compliance with City Ordinance No. XXX (Appendix X) and the City's NPDES Permit (Appendix X), proper erosion and sediment control at all sites of development is required to be established and maintained throughout the duration of the project and is inspected regularly for compliance. Sediments directly washing off a site, and into the canals created a mound of substrate for vegetation to establish and carry nutrients which many invasive species thrive on. CITY OF SEBASTIAN PAGE 11 INTEGRATED PEST MANAGEMENT PLAN IV. PONDS Overview There are dozens of stormwater "ponds" throughout the City. These include all of the ponds and dry retention areas that are located within City parks and properties, as well as the interconnected ponds of the Stormwater Park. Pond vegetation provides an ecological as well as an aesthetic benefit. If left to grow uncontrolled, however, the flood control and safety of these properties can be impaired. Do Nothing Option Too much aquatic vegetation in the ponds can very quickly reduce their stormwater storage capacity. This accelerated succession causes localized flooding problems. Also, many species of tall grasses growing around the pond edges can create dense thickets which are impossible for police and park visitors to see beyond; creating a serious safety concern. Many of the ponds also contain a fountain for aeration and algae control. Dense vegetation can damage the fountains by clogging the pump system or blocking the spray. The tolerance threshold for pest activity, before action is taken is considered high for these assets. Non -Chemical Methods In order to control vegetation, the following cultural and mechanical methods will be conducted routinely as part of standard proactive maintenance procedures within the City's stormwater system: • Dredging. When all or part of the ponds are at their lowest storage, the City can access the pond bottoms and edges with equipment to mechanically remove the vegetation and accumulated sediments. • Mechanical Removal by Contractor. During periods where invasive vegetation has spread too extensively at a location to be brought back under control by routine methods, a contractor may be hired with the equipment to cut and remove the vegetation by boat. • Fountain Aeration. A fountain installed in the center of the pond provides water circulation and increases the dissolved oxygen of the water. This inhibits vegetation growth and increases the habitat quality for aquatic animals as well. • Planting Native Emergent Vegetation. Maintaining a healthy, natural shoreline of native vegetation will help prevent the pest vegetation from re-establishing and enhance the habitat and aesthetic quality of the pond. CITY OF SEBASTIAN PAGE 12 INTEGRATED PEST MANAGEMENT PLAN V. DITCHES Overview Stormwater assets classified as "ditches" includes a massive 80 mile system of open ditches. The ditch system is a massive spider web connecting most of the ponds, and canals to one another. Vegetation in the ditches assists with the infiltration of the water through the soil and stabilizes the steep banks. However, the growth of vegetation must also be controlled enough to preserve the connectivity of the entire stormwater system. Do Nothing Option The overgrowth of aquatic vegetation around in the ditches can eventually decrease their storage capacity, creating localized flooding problems. The ditch vegetation can cause very costly blockages in the road crossing culvert pipes. Many of the ditches bisect blocks of residential lots and an overgrowth of woody vegetation from the ditches threatens utility and residential structures. The tolerance threshold for pest activity, before action is taken is considered very high for ditches. Non -Chemical Methods In order to control vegetation, the following cultural and mechanical methods will be conducted routinely as part of standard proactive maintenance procedures within the City's stormwater system: • Dredging. When the ditches are at their lowest storage, the City can access the ditch bottoms with equipment and mechanically remove the vegetation and accumulated sediments. • Sediment and Erosion Control at Development Sites. In compliance with City Ordinance No. XXX (Appendix X) and the City's NPDES Permit (Appendix X), proper erosion and sediment control at all sites of development is required to be established and maintained throughout the duration of the project and is inspected regularly for compliance. Sediments directly washing off a site, and into the ditches create a mound of substrate for vegetation to establish and carry nutrients which many invasive species thrive on. These sediments can travel with stormwater and enter the canals as well. • Mowing. The City maintains a contract for mowing of all right-of-way areas and ditch banks. Mowing the ditch banks reduces the self -seeding of the pest vegetation while still allowing the vegetation to remain established as it plays an important role in stabilizing the banks and filtering nutrients and sediments. • Mow at correct height. Mowing to low can thin out and starve the vegetation and mowing too high or not often enough can facilitate the further spread of the plants. • Always mow with sharp blades and Sanitize Tools. Dull mower blades cause uneven cutting and weaken the grasses. Vegetation can easily spread among sites by hitchhiking seeds and plant fragments on un-sanitized mowing and maintenance equipment. Cleaning the these tools between areas minimizes pest transport CITY OF SEBASTIAN PAGE 13 INTEGRATED PEST MANAGEMENT PLAN VI. FURTHER NON -CHEMICAL RECOMMENDATIONS Future Considerations In addition to the cultural and mechanical pest control methods currently being implemented within the City's stormwater conveyance system, observations of the areas and sub- committee member research prompted the following recommendations for future consideration (Figure 4): • Seawall Reconstruction. Reconstruction of seawalls that border most of the canal system. The seawalls hold back nutrient laden sediments from residential and commercial landscapes from entering the waters while keeping the banks stabilized. • Expanded Dredging of Open Water Dreas. Dredging of canal, pond, and ditch bottoms to de -muck the nutrient rich deposits that comprise the top layer of the substrate and remove seawall sediments, which readily accommodate emergent vegetation growth • Environmental Enhancements. Creation of a self -maintaining littoral shelf with native aquatic vegetation, which will provide healthy habitat and nutrient filtration for the • Pathogens. The control of some pest vegetation can be aided by pathogens such as specific bacteria or fungus, which are amended to the pesticides or the water itself. While these bioherbicides are currently under research and review, many studies have shown that they help provide more effective long-term control. • Stormwater Fee Credits. Utilize the existing Stormwater Fee Credit Program to incentivize private property owners to install a buffer zone of emergent vegetation along stormwater ponds and natural canal boundaries CITY OF SEBASTIAN PAGE 14 nFT CI SEBASTIAN �C• IPM B- MMITTEE SU HOMEFELiAN ISLAND AGENDA TRANSMITTAL FORM Board Meetinq Date: February 8th, 2021 Aqenda Item Title: VI.

Persistence, or the "lasting- power" of a pesticide on the surface of the leaves, stems, and fruit Once an EIQ value has been established for the active ingredient of each pesticide, field use calculations can begin. To accurately compare pesticides and pest management strategies, the dose, the formulation or percent active ingredient of the product and the frequency of application of each pesticide needs to be determined. To account for different formulations of the some active ingredient and different use patterns, a simple equation called the EIQ Field Use Rating was developed. This rating is calculated by multiplying the EIQ value for the specific chemical obtained in the tables by the percent active ingredient in the formulation by the rate per acre used (usually in pints or pounds of formulated product). EIQ FIELD USE RATING = EIQ x 7 ACTIVE INGREDIENT x RATE Source: Kovach, J., Petzoldt, C., Degni, J., and Tette, J. 1992. A method to measure the environmental impact of pesticides.
