RESOLUTION NO.98-__fi 1 <br /> structures. All discharges from the surface water management system shall meet the water <br /> quality standards of Florida Administrative Code Rule 17-3. These provisions shall be <br /> addressed in project site plans. <br /> 25. The developer shall design and construct the surface water management system so that <br /> maintenance of normal hydroperiods within preserved wetlands can be guaranteed against <br /> the negative impacts of activities within the project boundaries,and so that the functions and <br /> values provided by these preserve areas will be maintained. Via the site plan project <br /> development review and permitting process,the developer shall submit a plan establishing <br /> wetland control elevations and post-development drainage sub-areas for each wetland to St. <br /> Johns River Water Management District and Indian River County for approval. This plan <br /> may be included in the Preserve Area Management Plan. The plan shall demonstrate how <br /> sufficient quantities of surface runoff from portions of the developed areas will be conveyed <br /> to wetland areas in order to maintain or improve their exiting hydroperiod. <br /> 26. All elements of the stormwater management system shall be designed to prevent impacts to <br /> adjacent areas and to the receiving bodies of water. The developer shall prepare plans that <br /> reasonably demonstrate that these waterbodies and adjacent properties will not be negatively <br /> impacted by water quality, water quantity or timing of delivery. These plans shall be <br /> approved by St. Johns Water Management District and Indian River County prior to the <br /> construction of the surface water management system and prior to release of any project site <br /> plan. <br /> — " 27. To improve the quality of stormwater on-site,the streets and paved parking lots within the <br /> commercial areas shall be swept as necessary,but in no case less frequently than once per <br /> week. Sweeping shall be accomplished by vacuum type or vacuum regenerative type <br /> sweepers. Parking stops or bumps which may collect and concentrate contaminants,or <br /> which would interfere with efficient sweeping of paved parking areas,shall not be used <br /> outside the existing phase of the project. <br /> 28. During the site plan review process, the developer and Indian River County shall work <br /> together to minimize the amount of impervious surface constructed for the purposes of <br /> automobile parking on the Horizon Outlet Center site. The developer and the County shall <br /> consider the use of pervious parking lot materials where feasible and,in cooperation with the <br /> developer implementing an incremental parking lot construction program that initially <br /> reduces parking space/retail space ratios to a minimum with any increases tied to actual <br /> demonstrated demand. <br /> 29. Golf course management shall be addressed within the Preserve Area Management Plan <br /> (reference condition#18) prior to the construction of the golf course on the project site. The <br /> Preserve Area Management Plan shall provide details concerning the application of <br /> fertilizers,herbicides and pesticides on the golf course. The plan shall include methods for <br /> minimizing the impact of chemical runoff associated with golf course maintenance. <br /> 30. A vegetated littoral zone shall be established in the lake constructed on site. Prior to the <br /> expansion of the existing lake system,the developer shall prepare a design and management <br /> plan for the wetland/littoral zone that will be developed as part of that system. The plan may <br /> be incorporated into the Preserve Area Management Plan and shall be subject to approval by <br /> the St.Johns River Water Management District,and Indian River County prior to beginning <br /> any excavation activity. Littoral zones shall be constructed concurrent with lake excavation <br /> and final grading. Operational permits for the surface water management system shall not <br /> be issued nor shall a certificate of occupancy for any future portion of the project be issued <br /> until such time as littoral zones have been found to be constructed in conformance with <br /> approved plans. <br /> 6 <br />
