Comprehensive Plan Conservation Element as the easternmost building setback line from the ocean, with the exception of beach access dune crossovers that are allowed east of the line. o A requirement that substantially damaged oceanfront structures in nonconforming "footprints" be relocated westward, in compliance with current coastal regulations, even when such structures are substantially damaged during declared natural disasters. While on-site disposal systems (OSDS) associated with oceanfront homes are more vulnerable to potential erosion impacts than OSDS on inland home sites, state OSDS regulations address this potential problem by requiring that such systems, if they fail, be brought up to current standards and setbacks or otherwise be replaced by public sewer, where available. Since state regulations address this issue, no local policies are needed regarding OSDS associated with oceanfront homes. Water Resources Surface Water The Stormwater Management Sub -Element provides a detailed account of water quality issues in Indian River County. Following is brief summary of the sub -element: ➢ Urban drainage systems often consist of impermeable, enclosed structures, such as pipes and culverts which collect substantial amounts of runoff from impervious, "urbanized" areas. Water quality from urban runoff is often of poor quality, since little, if any, natural filtration or percolation occurs. ➢ Stormwater runoff carrying pollutants to the IRL from urban development can be reduced through the proper use of on-site retention facilities and best management practices (BMPs). ➢ Wetlands associated with the St. Sebastian River and the Indian River Lagoon serve an important function by reducing the flow of pollutants. ➢ Where mosquito impoundments have been connected to the lagoon, they contribute to enhanced water quality and marine habitat for the benefit of estuarine organisms. ➢ The Upper St. Johns River Basin restoration project, a cooperative effort between the ACOE and the SJRWMD, was recently completed. This project has improved the flood storage capacity of the Basin, and restored lands back to their historic configuration. The completed Basin project has decreased the amount of freshwater inflow (particularly during major storm events) to the St. Sebastian River and Indian River Lagoon via the C-54 canal, thus contributing to improved water quality in estuarine waters.
