The IRFWCD discharges into the Indian River Lagoon , an Estuary of National Significance and a St . Johns River Water Management District (SJRWMD) Surface Water Improvement and Management (SWIM ) program priority water body. In the East Indian River County Master Stormwater Management Plan (Master Plan ), a pollutant loading analysis showed that the three discharge canals of the IFRWCD convey large amounts of suspended solids , nutrients , and floating vegetative debris into the lagoon , seriously degrading estuarine habitat. The canals also transport tremendous quantities of human-generated trash (Styrofoam cups, plastic, bottles, etc. ) into the Lagoon . Treatment alternatives were investigated in the Master Plan . It was recommended that sediment and floating debris collection systems be used to effect a significant reduction in muck contributing solids, nutrients , floatables and trash into the Lagoon . Several of these BMPs were determined to be well-suited for placement within the limited space available in the existing canal rights-of-way. The two general types of improvements which appeared to be effective given the existing conditions were floating debris capture systems and structural pollution control devices. The need for this project is described in the November 1996 " Indian River Lagoon Comprehensive Conservation and Management Plan" under the Water and Sediment Quality Improvement section . Recommendations for large drainage systems, such as the IRFWCD, are found in Action FSD- 12, Freshwater and Stormwater Discharges Action Plan . The 2002 IRL SWIM Plan Update discusses the IRFWCD and the need to reduce TSS and nutrients in Chapter 5, page 133 . A major concern stated in the SWIM Plan is the total phosphorus loading from the IRFWCD being higher than that from the Turkey Creek basin which is 1 . 5 times larger in area . Methods to treat or control pollution from stormwater runoff (BMPs) have traditionally included practices that are typically land intensive (dry retention areas, wet detention ponds) and have low maintenance requirements. However, as land has become scarcer and more valuable in Florida , efforts have also been focused on treatment technologies that DEP Agreement No. G0182, Attachment A- 1 , Page 2 of 12
