The approved separation distance is 5.0 feet. This waiver approval applies to the existing absorption field only. Any future upgrade to the on- site wastewater disposal system will require all separation distances be met or another approval from this department.

Prior to placement of the new trench the old crib was pumped dry, crushed, backfilled in lifts and compacted with sandy in situ material. The area of the old absorption pit and underlying soils are now at or near original undisturbed condition. The pit consisted of 4' diameter perforated concrete rings with a 5' collar of silty gravel material. This material is similar to in situ material with slightly less silt and more gravel and was probably mined from another location on the lot. No drain field rock was found at or near the pit. Underlying soils on the lot are primarily sand with varying amounts of gravel and silt based on test holes recently completed. Absorption rates are typically under 5 minutes per inch. Very little horizontal migration of effluent is expected and absorption should be in a downward direction. Excavation on the lot indicated little or no migration from the existing absorption pit had occurred. We request a waiver be issued allowing the proposed and alternate absorption trenches to remain at the location shown. Sincerely, Michael E. Anderson, P.E. o''"'waOF 1414 u IS47 49th it* 1, __ �/ S/y/�9 MICHAEL E. AND RSON� zt at 000 c56 •S,' No.8/14/198I c '•_• o�tJ1d1I o7? SGS Ref.# 1193207001 Client Name Forge Engineering Inc.

The existing septic tank will be decommissioned in accordance with Municipal Code. We are submitting this permit application for the existing well and to construct the new septic system. The attached site plan identifies the location of the home and the existing well and septic systems along with the proposed septic location and alternate site. No conflicts exist between this proposed system and any other well or septic system on this lot or adjacent lots. The ground surface on the lot slopes gently to the south at grades approximating 10%. There are no slopes greater than 25% within 50 feet downslope of either the primary or alternate site. Topographic contours are shown on the site plan indicating the grade and direction of flow. Stormwater drainage will not impact this septic system. The new trenches will be constructed parallel to the slope as much as possible. Wells on this and adjacent lots are shown. The new system will be a minimum of 100' from all wells and surface water, and more than 5' away from the septic tank. Please refer to the attached test hole logs, soils lab analysis, plan and profile pages for the septic design. If this design is followed, there will be no adverse impacts to adjacent properties.
