According to available as-built informa Ɵon, the residence has an exisƟng sepƟc system that should consists of two (2) sepƟc tanks connected in series to a secƟon of Deep Trench absorpƟon field. The original system was installed someƟme prior to 1977, because records indicate it was upgraded in 1977. The 1977 upgrade consisted of adding an addi Ɵonal sepƟc tank and a new trench drainfield. This does not match current observaƟons in the field or the recent asbuilt survey. It appears only one tank is present. If differing condiƟons are discovered during construcƟon, it will be noted on the asbuilt drawings. However, the enƟre system is in need of replacement and will be upgraded to current standards. Based on the new asbuilt survey, the exisƟng sepƟc tank is located within the 100-foot separaƟon radius from the private water well on the property. The ExisƟng Well is located near the SE corner of the residence, approximately 75 horizontal feet from the exisƟng SepƟc Tank. ShiŌing the locaƟon of the new sepƟc is part of the design plans to increase the separa Ɵon distance. The new tank will be located approximately 86 feet from the exisƟng well, and therefore a waiver will need to be approved for construcƟon. Well Radii are shown on the design plans. A porƟon of the exisƟng drainfield is located outside of the property lines and within the ROW of E. 97th Avenue. This will be addressed in the re-design. The 100-foot separaƟon radius from the adjacent propertys well is shown on the design plans. There is only a narrow area available for the construcƟon of the new drainfield. See design drawings. A soil invesƟgaƟon was conducted on site on September 21,2025. A Single test hole was advanced and a percolaƟon test was performed. The Test hole was excavated to a depth of 17 feet and indicated +/- 6 inches of Organics/top soil above GW soils to a depth of 17 feet. No water table or bedrock was observed during the soil test. The PercolaƟon rate was determined to be 2 minutes/inch. See included Soils Log Percola Ɵon Test Report by Mike N Anderson dated 9/31/2025. Design CalculaƟons Flow Rate: 4 Bedroom Main Residence at 150GPD/Bedroom - Design Flow = 4 bedroom X 150 GPD/bedroom = 600 GPD SepƟc Tank Size: Minimum Tank Size shall be 1000 gallons plus 250 gallons for each bedroom over 3 per AMC 15.65.205 - 1000 + (250) = 1250 gallons PercolaƟon Rate: Soil TesƟng indicated a percolaƟon rate of 2 min/inch. ApplicaƟon Rate: - Per AMC 15.65.210 Table 2 for ConvenƟonal Subsurface Disposal Fields, The ApplicaƟon Rate for soils with percolaƟon rates of 1-5 Minutes/inch shall be 1.2 gallons/day/square foot. - Design ApplicaƟon Rate: 1.2 gallon/day/square foot Drainfield Area: - (600 gallons/day) / (1.2 gallon/day/square foot) = 500 Square Feet Drainfield Design: Deep Trench 1. The EffecƟve AbsorpƟon area of deep trenches is calculated as the area of the sidewalls below the invert of the distribuƟon pipe. - Required EffecƟve AbsorpƟon Area = Length of Trench x EffecƟve Depth x 2 2. An EffecƟve Depth of 7 feet will be uƟlized for this site. 3. Minimum Trench Length: L = 500/7/2 = 35.71 = 36 feet Variance Request: Due to site constraints and available construcƟon space, a variance will need to be approved for the installaƟon of the new SepƟc Tank. The new sepƟc tank will be located 85 linear feet from the onsite water well. This is within the code mandated 100 foot separaƟon distance. There is no available area on the property for construcƟon of a tank that would be outside the 100 foot radius. However, the proposed tank is further away from the well than the exisƟng tank improving the separaƟon distance. Also, water analysis indicates that current levels of Nitrates/Nitrites are below detectable levels. Replacing a failing tank with a new tank will help ensure this remains true. Furthermore, the proposed tank locaƟon is down grade from the well locaƟon. Any potenƟal overflow situaƟon would not approach the well locaƟon. Also due to site constraints and available construcƟon space, the longitudinal length of the proposed drainfield will not be aligned directly parallel to the exisƟng grade contours. The onsite well radius and the well radius of the adjacent property create a narrow strip of land that is available for drainfield construcƟon. If the drainfield were rotated parallel to the contour of the land, it would encroach into the protecƟve radius. The proposed drainfield is aligned as parallel to the contour as possible. The soil test hole indicated a consistent layer of GW soils to a depth of 17 feet. The deepest porƟon of the proposed drainfield will be approximately 5.5 feet above the boƩom of the test hole. A confirmaƟon test hole will be advanced in this area prior to installaƟon to ensure necessary 6 foot separaƟon from any potenƟal confining layer. Should you have any quesƟons or require any addiƟonal informaƟon, please do not hesitate to contact me. Sincerely, Logan M. Huber P.E.

The approved separation distance is 86.0 feet. This waiver approval applies to the proposed septic tank only. Any future upgrade to the on-site wastewater disposal system will require all separation distances be met or another approval from this department. Your request for a waiver allowing the disposal field orientation, where the long axis does not follow the contours of the original ground, has been approved.
