ATTACHMENT A- 1 REVISED GRANT WORK PLAN PROJECT NAME : PC South Algal Nutrient Removal Facility PROJECT FUNDING : $ 850,000 from 31912 ; $ 1 ,376,900 from TMDL grant = $2 ,226,900 REQUIRED MATCH : $ 1 ,440, 853 .40 for 31912 ; $4 ,049,947 for TMDL grant = $ 5 ,490, 800 .40 OTHER ADDITIONAL EXPENDITURES/NOT REQUIRED MATCH : $ 1 , 833 , 868 TOTAL PROJECT COST : $915519568 .40 LEAD ORGANIZATION : Indian River County COOPERATING PARTNERS : State of Florida — DEP Agreement No . LP31010 ($250 ,000 for pilot study & pilot construction, not identified in project costs in this Agreement), SJRWMD Cost-share agreement No . 27199 ($55 ,795 for initial design, not identified in project costs in this Agreement) PROJECT LOCATION AND WATERSHED CHARACTERISTICS : Geographic Location : Vero Beach ; Indian River County Impacted Watershed Name : Indian River Farms Water Control District South Relief Canal Drainage Basin Size of Project Impact : The Algal Nutrient Removal Facility ( ANRF) will be approximately 4 . 5 acres with associated peripheral facilities requiring approximately another six (6) acres . The developed site will be approximately ten ( 10 ) acres . The total site property is approximately 12 . 81 acres . Size of Drainage Area : 17 , 163 acres Latitude : 27 . 592522 Longitude : 80 . 398530 Hydrologic Unit Code : 03080203 Impaired waterbody affected : Indian River Lagoon ( IRL Central B Project Zone), WBID : 5003B , TMDL adopted for Nutrients (TN and TP) Impairment : The health of the Indian River Lagoon ' s seagrass is the benchmark for measuring the progress of the TMDL process . Healthy seagrass and increasing seagrass coverage is indicative of a health Lagoon. The project will dramatically reduce the amount of dissolved nutrients (nitrogen and phosphorus) entering the Indian River Lagoon ( IRL) through the Indian River Farms Water Control District ' s ( IRFWCD) South Relief Canal . Therefore , the project will dramatically reduce the potential for harmful algal blooms, including macroalgae such as Gracilaria SP. , in the IRL that can be detrimental to seagrass and marine life . The project will also significantly reduce the amount of suspended solids and sediment that enter the IRL and it may also reduce to a lesser degree the color of the water. It will also increase the water' s overall dissolved oxygen levels . Management of these parameters will benefit the IRL ' s seagrasses by reducing muck deposits, reducing settlement of sediment on seagrass leaves, improving oxygen availability , and increasing the penetration of light through the water column . BMAP Status : Indian River Lagoon BMAP under development Land Ownership Status : Land necessary for the construction of treatment infrastructure has been acquired in 2012 , approximately 12 . 81 acres for $750 ,000 . Title is held by Indian River County .
