S) The historic tidal creek between the marshes discussed above <br />should be restored via a wide, shallow swale cut through the <br />existing landfill, from the present marsh to the Indian River. <br />The current proposal already includes this swale as a flushing <br />channel for the proposed marina 112. <br />6) The existing freshwater systems (marshes "B" and "F") should <br />-be restored as productive freshwater marshes as appropriate. <br />Marsh "B" is an ideal candidate for use as a polishing pond <br />for effluent from the freshwater lake system. Occasional <br />overflow could be routed into either the restored impoundments <br />or the tidal creek. Marsh "F" is the most disturbed wetland <br />on the site. This area could also be used as a stormwater <br />polishing pond if necessary, or it could be developed as <br />desired by the applicant, in recognition of environmental <br />enhancement of the remaining wetlands. <br />7) Wetlands "D" and "E" should be preserved. Minimal alteration <br />to improve management options or enhance flushing could be <br />appropriate. <br />These seven recommendations are an appropriate framework for <br />development of an acceptable wetland management plan. We would gladly <br />review proposals submitted by the applicant, and strongly recommend that <br />any scenario for wetland alteration and management on this tract be <br />submitted for review and acceptance by the Technical Subcommittee on <br />Mosquito Impoundments of the Governor's Working Group on Mosquito <br />Control. <br />Thank you for the opportunity to review this ADA. Decisions <br />regarding development of this tract could, in effect, determine the <br />future of the entire Indian River system through establishing a <br />precedent for other owners of tidal or impounded wetlands, and by <br />permitting or restricting major navigational dredging projects in the <br />Indian River Aquatic Preserves. Development as outlined in our <br />recommendations could provide a state-of-the-art showpiece to serve as <br />an example for future development, and restore the fish and wildlife <br />values of an impacted wetland system. Please call me if we can be of <br />further assistance. <br />Sincerely yours, <br />/ 5�� /d' <br />Brian S. Barnett <br />South Florida Section Leader <br />Commissioner Scurlock inquired if these comments were made <br />at the Regional Planning Council, and Dr. Swain believed they <br />were made only to the Planning g Zoning Commission and the Board. <br />Chairman Lyons noted that the letter of August 7th written <br />by Brian Barnett was addressed to the Regional Planning Council, <br />and he believed there were in receipt of it.
