Farrell, PE. The OWTS is designed with capacity to serve both the single family residence and the detached ADU, for a total of five bedrooms. The system consists of a Valley Precast 1,250 gallon, single compartment tank with effluent filter and high water alarm placed on the outlet tee, followed by a 2,000 gallon Valley Precast three-compartment recirculating/dose tank which will send wastewater to two, Orenco Advantex Series AX 20 pods for nitrification using an Orenco PF 500512 pump. Nitrified effluent flows to the splitter valve for recirculation to the 1,250 gallon first tank for denitrification then is dosed using an Orenco PF 751512 pump to 720 square feet of soil treatment area via one bed consisting of three rows of 20 Infiltrator Quick 4 Plus Standard chambers for a total of 60 Infiltrator chambers. Distribution lateral details, along with orifice size, spacing and orientation are on the design drawing. The contractor must verify that all electrical components and inspections are covered under the electrical permit associated with the Orenco Vericom control panel (Model VCOM-AX20B2) and pump connections. The alarm must be connected to a separate circuit. Additional pump details are on the design drawing. Advantex systems must conform to the CDPHE technology approval letter dated May 1, 2018, including configuration in mode 3 for treatment level 3N.

(JVA) has prepared a design of an onsite wastewater treatment system (OWTS) to serve Lot 74 within the Frost Creek PUD. JVA is the designated engineer to process all OWTS permit applications within Frost Creek. JVA has prepared the OWTS design to be in general conformance with OWTS requirements of the PUD. The 2020 annual Water Quality Monitoring Report prepared by Wright Water Engineers documents exceedances of the 85th percentile background concentrations during sampling events in 2020. The report states the following ‘While the concentrations observed in 2020 were high for Total Phosphorus and Total Suspended Solids in surface water, upon evaluation of the pattern of concentrations of each water quality parameter for surface and groundwater at the Frost Creek PUD, there are no evident increasing trends in the concentration of the sampled parameters that were outside of the range of historical values. Therefore, all three components of the trigger limits have not yet been met, and mitigation action is not yet required.’ Sincerely, JVA, INCORPORATED By: _______________________ Simon Farrell, P.E.

This report provides information needed to support the design of an OWTS including: results from the preliminary investigation, the site visit, and the soil evaluation. Design calculations are included in the drawing Permit Set attached. PRELIMINARY INVESTIGATION In preparation for the site visit and soil evaluation, a preliminary investigation was conducted the week of October 28th, 2020. Architectural site plans, aerial imagery, and previous Geotechnical investigations were used for the preliminary investigation. Geotechnical investigations were performed by HP Geotech in October 2002 across Frost Creek for OWTS suitability. Results from the HP Geotech report showed that for the proposed location, Test Hole A and B had a topsoil from zero to six inches deep and a silty sand from six inches to eight feet deep. No groundwater was encountered in either hole. SITE VISIT AND SOIL EVALUATION A site visit and soil evaluation were conducted the week of November 4th, 2020. The purpose of the site visit and soil evaluation was to confirm hypotheses from the preliminary investigation, identify the topography, landscape position, vegetation, and site constraints for the proposed OWTS, and to conduct a visual and tactile soil evaluation of the underlying soils where the proposed soil treatment area (STA) is to be located for both suitability and sizing. The topography of the site slopes slightly from west to east. The dominant vegetation at the proposed OWTS consists of native grasses. Site Constraints are shown in the Permit Documents. For the visual and tactile soil evaluation, two soil profile holes were excavated using a tracked excavator in the locations identified in the Permit Documents. As seen in Table 1 below, soil morphology for Soil Profile Hole One from zero to six inches was loam topsoil, and from six inches to eight feet deep was Soil Type 2A. Soil morphology for Soil Profile Hole Two was identical to Soil Profile Hole One from zero to six inches was loam topsoil, and from six inches to eight feet deep was Soil Type 2A. No redoximorphic features, indicating seasonally high groundwater, were observed in either hole. Figures 1 through 4 below show the soil profile holes and corresponding morphology. Therefore, Soil Type 2A was identified as the soil type. Frost Creek Lot 74 Site and Soil Investigation 11/30/20 2 of 2 Table 1 – Visual and Tactile Soil Results Profile Hole Depth (ft.)

The updated site plan with the fields stacked looks good to me. This location doesn’t change the pump calculations and, as Jeff brought up, it allows for drainage spacing between the fields and the court. If the fields need to shift a bit more SE to allow more room between the two that is ok too as long as we maintain the 10’ offset from the property line. Thanks for reaching out and coordinating this shift with me. JULIE N.
