Comprehensive Plan Sanitary Sewer Sub -Element Areas with small lot sizes less than '/ acre especially those constructed prior to 1983. Residential subdivisions that meet those criteria are identified in Table 3.A.3. • Areas with intense land uses. Intense land uses means commercial, industrial or equivalent uses or residential uses greater than 6 units/acre. • Environmentally Sensitive Areas. This means areas within 500 feet of aquifer recharge zones, as identified in the Aquifer Recharge Sub -Element of this plan; within 500 feet of any public water supply well; within 500 feet of the Indian River Lagoon, the St. Sebastian River, or any body of water that drains into them. • As identified in the 2017 Septic to Sewer Study: Evaluation and Ranking by Utilities. • Areas identified by the DOH -Indian River as potential threats to public health. • New developments on oceanfront and riverfront lots For planning purposes, a history of septic system repairs is defined as follows: For subdivisions of 10 or fewer lots, this means 20% failures in five years. For subdivisions of 11 to 75 lots, this means 10% failures in five years. For subdivisions of more than 75 lots, this means 2% failures in five years. Methods that allow for a higher level of effluent treatment and reduction of contamination include: installation of a "performance based system", providing a 24 inch separation between the bottom of the drainfield and the wet season water table, and providing at least a 75 foot setback between septic systems and wells and/or surface waterbodies._Generally, the most effective and efficient way to correct the wastewater problem of those subdivisions is to connect them to the regional system TREATMENT In addition to septic systems, public and private treatment plants provide wastewater treatment within the county. In Indian River County, large regional public treatment plants now predominate. Consequently; major treatment issues in the county relate primarily to ensuring sufficient capacity (either on-site or off-site) to accommodate projected growth. If wastewater demand were allowed to exceed the county's treatment capacity, untreated sewage would have to be discharged. That would result in health hazards and environmental degradation of surface water bodies. To prevent such an occurrence, the county must continue its policy of approving new development only when sufficient capacity will be available. In this regard, the county's computerized concurrency management system and its capital improvements plan ensure that capacity will be available to serve new development concurrent with demand.
