The annual report shall include documentation verifying that no applicants approved during the reporting year (renters, lessors or owners of boat slips) have incurred violations of marine laws (within five years of application for slip use), the nature of which may pose a risk to Manatees. Screening of prospective renters, lessors, or owners of slips may be discontinued at such time that a slow or idle speed zone in the entire inter -inlet area (Sebastian and Ft. Pierce inlets) is established. c) In lieu of the screening condition described above, the developer may arrange to provide for strict enforcement of existing speed zones and other marine laws. Such an arrange- ment, if pursued as an option by the developer, must be approved by the County and Treasure Coast Regional Planning Council, prior to effective replacement of the screening condition described above". SECTION 2. Under "DRAINAGE", item 25 is hereby amended to read as follows: "25. The developer shall design and construct the stormwater management system to retain or detain with filtration, as a minimum, the first one -inch of runoff or the runoff from a one-hour, three-year storm event, whichever is greater. Required retention volumes may be accommodated in a combination of exfiltration trenches, vegetated swales,' dry retention areas, lakes with vegetated littoral zones or other suitable retention structures. All discharge from the surface water management lakes shall meet the water quality standards of Florida Administration Code Rule 17-3. Direct discharge of untreated surface water runoff from off-site sources into the marina basin(s), the estuary/water- way system or the Indian River Lagoon which would degrade water quality'within these systems shall not be allowed. The stormwater management system shall be designed to prevent water quality degradation of on-site surface water from off-site runoff sources. Final drainage plans of the stormwater management system shall be submitted to the Florida Department of Environmental Regulation, St. Johns River Water Management District, Indian River County, and the Treasure Coast Regional Planning Council. The plans shall include plan view and cross- sectional drawings (certified by a professional engineer) of the swale system, exfiltration trenches, lake systems and outfalls to waters in the lakes; and all pertinent elevations including existing seasonal high groundwater elevation, normal water level, design high water level and control structure inverts. Clearing of the land shall not begin until the plans are approved by the appropriate agencies. Direct discharge of untreated surface water runoff from off-site sources into the marina basin(s), the estuary/water- way system of the Indian River Lagoon which would degrade water quality within these systems shall not be allowed. The plans shall be approved by the County and Treasure Coast Regional Planning Council in consultation with the Florida Game and Freshwater Fish Commission in conjunction with any necessary approvals of permits from St. Johns Water Management District, prior to any land clearing, excavation, or construction on site". 51 FEB 5 1986 Box 6'3 mG;E 540
