Published as-built informaƟon is unavailable for the property. The property was an original homestead property that was subdivided into what is now known as Roseberry Park Estates. The residence is currently u Ɵlizing a Log Crib sepƟc system that needs to be replaced due to reconstrucƟon of the building. From my understanding the Log Crib was originally installed someƟme in the 1960s. The property owners have the intent of building addiƟons onto the building and adding bedrooms in the future. For this reason, a system sized for 4 bedrooms is being designed and constructed. A soil invesƟgaƟon was conducted on site on June 8th, 2026. A Single test hole was advanced and a percolaƟon test was performed. The Test hole was excavated to a depth of 16 feet and indicated 2 feet of Organics/top soil above well graded sand with gravel to a depth of 16 feet. The Percola Ɵon rate was determined to be 3 minutes/inch. See included Soils Log Percola Ɵon Test Report by Logan Huber P.E. dated 6/8/2026. The Water Table was encountered at a depth of 15 feet and a monitoring tube was installed. AŌer one week of monitoring, the groundwater level reached equilibrium at a depth of 14 feet-7 inches below ground surface as measured in the field. The groundwater elevaƟon has been adjusted up from there by one foot to a depth of 13 feet-7 inches feet to account for seasonal variaƟon. The ExisƟng Private Water Well for the property is located within the basement of the exisƟng building. A 100 foot well protecƟon radius is shown on the proposed construcƟon drawings. 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 3 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 1.20 gallons/day/square foot for deep trench type systems. - Design ApplicaƟon Rate: 1.2 gallon/day/square foot - Historical Soils Logs and PercolaƟng tesƟng of neighboring properƟes indicate the soils of the area are relaƟvely consistent. Two available reports; one for the property to the North and the other for the property to the North-West, indicate percola Ɵon rates of 1.7 Min/Inch and 1.2 Min/Inch respecƟvely. Drainfield Area: - (600 gallons/day) / (1.20 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 5.5 feet will be uƟlized for this site. 3. Minimum Trench Length: L = 500/5.5/2 = 45.45 = 46 feet I am unaware of any adverse impacts this installaƟon would have on any wells or sepƟc systems constructed in the adjacent area. Should you have any quesƟons or require any addiƟonal informaƟon, please do not hesitate to contact me. Sincerely, Logan M. Huber P.E.
