Site Evaluation. 1. Information obtained during the soil and site evaluation will determine which type(s) of IOWDS may be utilized for an individual lot. 2. Prior to completing the Soil and Site Evaluation/System Recommendation, the Environmentalist shall visit the lot and conduct the soil and site evaluation. 3. The soil determinations will be made based on soil borings to a depth of five feet or to a depth sufficient to reach a restrictive horizon. Restrictive soil or site conditions may preclude the use of any subsurface disposal system. 4. A soil and site evaluation will be based on the following criteria: a. Absence of or protection from frequent flooding. b. Landscape position with good surface runoff. c. Slopes of less than 15%. d. Depth to high water table of greater than four feet. e. Depth to bedrock, fragipan or plinthite of greater than four feet. f. Soil texture and color defined by the Natural Resource Conservation Service as indicating good drainage and suitability for soil absorption, based on a soil boring of five feet. g. Available area in which to install an individual onsite wastewater disposal system meeting all requirements of this regulation. The area for repairs and future extensions shall be no less than 50% of the space required for the recommended system. Systems utilizing surface land application discharge are exempt from the 50% additional area requirement. 5. The noncompliance of one or more of the above items may require a design alteration of an underground system.
