I / J ^ <br />I <br />k <br />TO: <br />FROM: <br />Jeanne A. Mabusth, Asst. Zoning Administrator <br />Michael P. Gaffron, Septic System Inspector <br />DATE: February 9, 1979 <br />SUBJECT: Audrey Heiser Property, Lots 4-5-6, Block 2, Hillside Park <br />testing and mapping has been done by Hickock & Associates to identify <br />suitable areas for use as drainfield. <br />s ss.".r.S" <br />use as drainfield due to the proximity of neighboring wells and an <br />field now and one future drainfield for the proposed home. This <br />proposal requires a number of variances from the septic system <br />ordinance: Required Proposed <br />1, setback variance for drainfield <br />from neighboring wells.75'60' <br />I feel this variance is allowable from a health <br />standpoint since state code requires a minimum 50 <br />setback if the well(s) are over 50 deep. Well <br />to the north is 98' deep, well to the south is <br />(by owner's understanding) about 200' deep. <br />2 Variance from requirement of 10,000 s.f. dedicated area for <br />drainfield to allow 6,000 s.f. The 6.000 s.f. could be enlarged <br />to about 7.000 s.f. by allowing drainfield up to 10' from property <br />line rather than 20* in the code. PCA standards allow It from <br />property lines. <br />Also note that slopes on the drainfield site range from 16% to OX <br />which is in the maximum range for drainfield. Special design <br />considerations will be needed for the drainfield to ensure no <br />sidehill seepage will occur. <br />S3^
