We propose to remove and replace the existing septic system per the attached design by installing one shallow trench and 1000-gallon tank to serve the existing 2- bedroom residence. The design is based on the MOA record documented test holes conducted by Mike E Anderson, PE. No groundwater was observed at test hole excavation or monitoring per these documents. With this submittal we are requesting continuance of MOA Waiver #WR000041 of 3 of the existing field to property line per the reasons stated on the waiver dated in June of 2000 and issued by the MOA. Furthermore, the improved material of the septic tank will be beneficial and if possible at construction the field will be moved further away with from the property line. We believe continuance of this MOA waiver is justifiable per this and a permit provision could be noted. The slopes are moderate at 5-10% at the proposed upgrade location. The lot and area are served by private water. The design will not impact any of the neighboring properties. Please contact us if you have any questions. Sincerely, Curtis Huffman, P.E.

Lot lines were not well defined during the construction process and accurate measurements were not available until the final as-built for the house was surveyed. Soils in this area were found to be the most effective on the lot for the absorption of septic effluent. We also r~oted percolation rates were much better at shallower levels. The location of the absorption trench should provide effective treatment of the septic effluent. The new trench is more than 100' from wells on this and adjacent lots. I! is also acceptable distances from the septic system to the east and does not conflict with any easements. We therefore recommend that a waiver be issued allowing the trench to be located 3' from the east property line Sincerely, Michael E. Anderson P.E.

We are hereby requesting this permit be issued to construct a new septic system to serve the house proposed for the lot. The attached Site Plan and backup documentation shows the location and configuration of the new septic system. A well is currently in place on the lot and is also shown on the Site Plan along with the 100' protective radius. A teSthole was placed on the lot in July of last year by S&S Engineers. A second testhole was recently placed to verify conditions and determine design parameters. Silty gravel was found from 1' below the surface to the bottom of the testhole. A percolation rate of 9.2 minutes per inch was attained at a depth of 5.5'. The S&S percolation rate was slightly slower at 20 minutes per inch No groundwater was encountered in either hole and none was noted during the monitoring periods. We have therefore designed a deep trench absorption system based on the slower percolation rate. The distribution p~ping will be placed at 4' below the ground surface and 7' of drainfield rock will be placed in the trench. The total depth of the trench will be 11' below the original ground surface. The length of the trench will be 55'. The lot surface slopes from north to south at rates varying from 3% to 5% with a slight grade from west to east. The trench will be placed perpendicular to the slope as required by the Municipa Ordinance. The existing drainage pattern on the lot will be maintained through final development. If the system is constructed in accordance with our design the following statements apply: 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 system, if constructed as designed, will have no adverse impact on existing se ptic systems in the area or those to be constructed in the future. Lot'2, Lennie Heights April 7, 2000 Page Two The system, if constructed as designed~ will have no adverse ~mpact on reserved space, either surface or subsurface, on any lots located in the area. The system, if constructed as designed, will have no adverse impact on drainage patterns m the area The current drainage pattern will be maintained. Sincerely, Michael E. Anderson P.E.

WJf rr�Y3 ;t`�s!=e; ° CE 11.2592 1` 11120/18 41 On July 26, 2018, we performed a septic adequacy test on the trench at 23819 Lennie Circle. Although the trench was less than half full when we started, the absorption rate was less than expected. The following are our calculations showing it absorbed more than 300 gallons in the 24- hour period. The trench is 55' long, Y wide, and 7' deep, for a total capacity of 1150 ft3. Void space, assuming 40%, is 462 ft'). This equates to approximately 41.25 gallons per inch of rise in the trench. When we filled the trench with 956 gallons of water, it rose 17". That is the equivalent of 701 gallons, meaning that 255 gallons were absorbed. In the next 2.5 hours it fell 3", absorbing an additional 124 gal. The total absorbed in 24 hours is therefore 379 gallons, enough for a 2 -bedroom home. The trench was less than half fidl at the start of the test, so we are confident that the trench is not in failure. Although the house was occupied, and we did not do a presoak, we theorize that this trench has been underused for a significant period of time. This would mean that the liquid levels have fallen down into the portion of the trench that is mostly plugged. With regular use, the liquid levels would rise to higher soil levels which would more readily absorb liquid.
