Comprehensive Plan Santa ry Sewer Sub -Element areas with a high concentration of commercial/industrial use, .and areas .with. construction that predates 1983: According to the United States Department of Agriculture's Soil Conservation Service, Soil Survey most of Indian River County's soil has severe limitations for the use of septic lank systems. Combined with the cEounty's high wet season water table, this.creates a high potential for groundwater and. surface water contamination problems. Since 1983, Fee �r��for new construction, the WX44BDOH- has requiresd that the bottom of drainfields be at least 424 inches above the wet season water table-. To meet this. requirement, ically slightly limited soil may be added to the site creating a mound. Also, a X75 foot separation requirement must be met between wells and/or waterbodies and septic tank -systems. r,equifement must be When parcels platted or recorded after 1972 meet minimum lot size requirements T T ideP he&egnd the above conditions, septic tans sy tem performance is considered adequate for developments within the cEounty. Another pr-ebler t -issue with septic systems is the possibility of w sere leaebate effluent from a septic t-a�-s sv tem entering waterbodies in the cEounty.. This problem must be examined carefully, especially on the barrier island, in areas near the Indian River Lagoon, in areas near the St. Sebastian River, and in areas adjacent to canals, lakes or wetlands. To summarize, the problems with septic tank -systems are listed below: • Physical limitations existing in Indian River County o A high water table of less than 10 inches as described in the USDA Soil Survey is found in almost all areas of the county, especially .during `'i.e. .r -A -4-11s Of the wet season June through October. o Ninety-three percent of the county's soil has an .~deny.. . pedi6 h^" izen (a "est -r -i ive layer- eften eewtpr-ised of sandy elay leam) and, therefore, is not suitable fer- septie tanks.
