Insufficient survey control was apparently used in the location of the absorption trench as it was constructed at 6' from the east property line and 2' from the south property line. Both the primary and reserve sites were constructed at the same time. The subdivision is served by the Municipal water system and no conflicts exist with the neighboring septic system. Accepting soils in the area of the absorption system are clean gravel with excellent absorption characteristics. No migration of effluent is expected.

Inspection Report: Please provide. Note: Review of this waiver request is not complete, and is on hold until the final inspection report and asbuilt drawings are made available for review. The original design for the septic system on this lot was completed by Anderson Engineering in October of 2002. We ha( little contact with the owner after that point. The system was constructed in May of 2003 by Everett Caulkins. At the time was an experienced installer and for many years had been certified by the City. The inspections were called in and recor by the City. We are unsure who actually called them in and assume it was the excavator. The design was apparently changed in the field and the owner and installer thought they were placing both the original and alternate absorption sites Although The trench size is more than sufficient for the primary site it is not large enough to meet both the primary and alternate requirements. An alternate site is shown on the east side of the existing driveway serving the home. We became involved recently when the owner decided to sell the house and needed the COSA certification. Additional cleanouts were added and the length, width and depth of the absorption trenches were verified. It is our opinion the exist system more than meets the requirements for the four bedroom home on the lot. A lot line waiver is necessary as the absorption trenches are less than 10' from the west and south property lines. r'�A7 r MUNICIPALITY OF ANCHORAGE C, ?'', Development Services Department �X On -Site Water & Wastewater Program 4700 South Bragaw Street P.O.

We are therefore requesting a permit be issued for the construction of a new septic system to serve the new home. The attached Site Plan and backup documentation identify the location and configuration of the new septic system and alternate site and the parameters used in the design. Also identified on the plans are the proposed water service line and the test hole location. Drainage arrows are also shown and current drainage patterns will be maintained after construction. Municipal water and sewer serve all adjoining properties. This lot is served by Municipal water, but the sewer line does not cross the frontage of his property. The test holes placed near the location of the proposed absorption trench indicated gravel with varying amounts of silt with a percolation rate of less than 2 minutes per inch and 15 minutes per inch. No ground water was found and none was noted during the monitoring period. We are therefore proposing to construct a deep absorption trench system with a 37' long trench with an 8' effective depth. The distribution piping depth will be 3' below the surface. Total depth of the trench will be 11'. The alternate trench will be 47' long to compensate for the slower percolation rate. The primary trench will be extended 5' longer than design requirements. The ground surface on the lot slopes at shallow grades from north to south. The absorption trench will be constructed parallel with the slope as much as possible in conformance with Municipal requirements. All components of the new septic system will be constructed a minimum of 10' from the water service line on the lot and on the adjacent lot. The system will also be constructed a minimum of 100' from any surface water in the area. Some surface water was noted in the electrical easement at the back of the lot. If the system is constructed in accordance with our design the following statements Lot 19, Tract B, Eaglecrest No. 1 October 7, 2002 Page Two apply: 1. The system, if constructed as designed, will have no adverse impact on the wells in the area or those to be constructed in the future. The subdivision is currently served by the Municipal water system. 2. The system, if constructed as designed, will have no adverse impact on existing septic systems in the area or those to be constructed in the future. 3. The system, if constructed as designed, will have no adverse impact on reserve space, either surface or subsurface, on any lots located in the area. 4. The system, if constructed as designed, will have no adverse impact on drainage patterns in the area. The current drainage pattern will be maintained. Sincerely, n `1D a L xL Michael E.
