NOV 13 1985 <br />BOOK 62 PAGE 48 <br />--._ The developer, through deed restrictions will preserve approxi- <br />mately 274 ± acres of impounded salt marshes. This area will <br />not be disturbed except for culvert installations at various <br />points to improve water quality and biological productivity by <br />increased flushing. Existing dikes will be used as a nature <br />trail for property owners and on a scheduled basis for Indian <br />River County school children. <br />To further improve the management of the impoundment area, the <br />applicant is proposing to construct a new pumping station with <br />a capacity of transferring 11,000 gallons of water per minute <br />from the Indian River into the mosquito impoundment area. <br />Replanting of wetland vegetation will also be included in <br />several axpas as depicted on the attached application drawings. <br />On December 13, 1984, the Planning & Zoning Commission granted <br />preliminary plat approval to Orchid Isle Estates Subdivision, <br />subject to.the condition that the Board of County Commissioners <br />accept the applicant's $52,500 in lieu of the dedication of <br />five public water access easements at the time of final plat <br />approval. In order for the applicant to receive a land deve- <br />lopment permit and commence construction of the ..subdivision's <br />on-site improvements, permits allowing the."'alteration of <br />wetland areas must be obtained from the DE.R., Army Corps of <br />Engineers, St. John's River Water Management District, and <br />Indian River County. <br />ALTERNATIVES & ANALYSIS: <br />The Planning and Development Division reviews and submits <br />comments on dredge and fill applications to the permitting <br />agencies based upon the following: <br />- The conservation & Coastal Zone Management Element of the <br />Indian River Comprehensive Plan; <br />Coastal Zone Management, Interim Goals, Objectives & <br />Policies for the Treasure Coast Region; <br />- The Hutchinson Island Resource Planning & Management <br />Plan. <br />- The Code of Laws and Ordinances of Indian River County; <br />- Indian River Lagoon Aquatic Preserves Management Plan. <br />The applicant has prepared a management plan for the Pine <br />Island mosquito impoundment (impoundment #6) which will restore <br />a significant amount of its pre -impoundment functions. <br />Reconnecting Impoundment #6 to the Indian River lagoon during <br />the non -mosquito producing season- with culverts will be a <br />significant contribution to the estuarine ecosystem as compared <br />to its present isolated condition. The flapgates to be used <br />(see Map#2, Detail B) also allow tidal intrusion during the <br />mosquito producing season if water levels in the Indian River <br />exceed impoundment water levels. <br />The Indian River Mosquito Control District (IRMCD) will be <br />responsible for impoundment water maintenance. The seasonal <br />flooding regime will be as follows: artificial pumping of <br />estuarine water into the impoundment will cease by September 1. <br />To minimize the release of a sudden surge of impounded water to <br />the estuary, the flapgates will be opened when fall high tides <br />reach impoundment water levels. All culverts will be opened by <br />September 15. <br />40 <br />
