In 2001 , Indian River County began master stormwater planning efforts for <br /> the 53 , 000acre Indian River Farms Water Control District (" IRFWCD" ) drainage basin . <br /> The basin drains through a 300 mile canal network that discharges from three relief <br /> canals (North , South , and Main Relief Canals) to the Indian River Lagoon (" IRL") . The <br /> Main Relief Canal drains 21 , 705 acres and carries approximately 50% of the basin <br /> discharge flow and pollutant loads . These planning efforts included development of <br /> best management practices to reduce pollutant loadings from the canals to the IRL . <br /> B. One project described in the November 1996 " Indian River Lagoon <br /> Comprehensive Conservation and Management Plan" , in the Water and Sediment <br /> Quality Improvement section , is the Project as hereinafter defined . C. Indian River <br /> County will construct a large treatment system on the Main Relief Canal in Vero Beach <br /> to remove coarse solid materials from canal water flowing to the IRL. The system will <br /> treat 294 cfs draining from a 21 , 705-acre basin with 50% urban and 50% agricultural <br /> land uses . The system will treat two pollutant components, suspended sediment solids <br /> and floating and submerged vegetation debris. The treatment facility will include a <br /> chambered sediment sump system , sump pumping system , a bar screening system <br /> including 1 -inch and 1 /8-inch spaced bar screens and a continuous cleaning <br /> mechanism . The water will first pass through the chambered sediment sump system , <br /> estimated to remove 65% of influent sediment TSS . The bar screens will then collect <br /> coarse, floating and submerged plant material , with an estimated 80% efficiency . <br /> Periodic pumping of the sediment sumps will maintain sump performance . Traveling <br /> rakes will remove the plant material trapped on the fixed bar screens and deposit that <br /> material in disposal containers . All of the foregoing Main Relief Canal bar screen <br /> system stormwater retrofit facilities herein collectively referenced as the (" Project") <br /> D . The County has received a $725 , 500 Section 319 (h) grant from the United <br /> States Environmental Protection Agency through the Florida Department of <br /> Environmental Protection ; $705 , 500 of which is earmarked for construction of the <br /> 1 <br />
