The purpose of our site visit was to inspect the installation of the septic system. Kirk Weems, from the ECEH Department was there too. The system was installed in overall compliance with the septic system design, Drawing No. 22- 3613OWTS.dwg, revised, July 26, 2023. At the time of the inspection we observed the following: They installed a 1500-gallons, two compartments, precast, concrete, septic tank by Valley Precast on the east side of the residence under construction. The building sewer line was about 57 feet long, 4-inch diameter SDR35 pvc pipe. Double cleanout was constructed on the sewer line, at about 12.5 feet south from the northeast building corner and about 3 feet east from the building, as shown on the as-built sketch.. The inlet and outlet of the tank had the T’s installed. The tank access ports had 36-inch corrugated, plastic risers with green, plastic covers. The covers were secured with nuts, bolts and screws. In the outlet tee, an effluent filter was installed. One hundred chambers were required. One hundred and seven (107), Q-4 Plus, Standard Infiltrator Chambers were installed in five trenches, with twenty-two infiltrators in each of the first four trenches, and 19 chambers in the last (fifth) trench. There was a minimum of 4 feet separation between the trenches. The rows of infiltrator chambers, were connected with serial distribution. All inspection ports were installed (in the end caps of the first and last chamber of each row of infiltrators). The effluent line from the septic tank to the leachfield was about 17 feet long, 4-inch diameter SDR35 pvc pipe. The septic tank covers, the inspection ports on the STA, and the closest stream, were located by the surveyor, Matt Slagle, PLS. There is no other warranty either expressed or implied.

The purpose of our site visit was to observe and evaluate an area for the proposed onsite wastewater treatment system (OWTS) for the proposed 5-bedroom residence. The OWTS will consist of a 1500-gallons, two-compartments concrete septic tank by Valley Precast with an effluent filter, and a Soil Treatment Area consisting of 100 Quick 4 Plus, Standard Infiltrator Chambers in trenches connected with a serial distribution. The site plan by your architect Greg Macik, NCARB, TAB Associates, Inc., was used as a basis for the septic system design. Directions to the site from Edwards are as follows: from US Highway- 6 turn right onto Hillcrest Drive, continue north through the I-70 underpass as the road turns into Beard Creek Trail for about 375 feet to Timber Springs Drive on the left. Go through the gate and continue to 300 Timber Springs Road. The building site is on the left side of the road. . ! Preliminary Investigation G Address: 300 Timber Springs Road, Eagle County, Colorado. G Legal Description: Lot 6, Timber Springs Subdivision, Eagle County, Colorado. G Existing Structures: At the time of our site visits there were no structures on the property. G Location of existing and proposed wells on property: The existing well was near the road and about 170 feet NE from the proposed Soil Treatment Area. G ECEHD (Eagle County Environmental Health Department) records: No previous records. The property was vacant G Topography: The topography of the leachfield site is moderate with an average slope of about 25 percent. Drainage is to the east-southeast.

Reconnaissance G Landscape position: The proposed STA will be located in the Back/Side Slope Position northeast from the proposed residence. G Topography: The topography of the proposed leachfield site is moderate. The trenches with rows of infiltrator will run along the contours. G Vegetation: To site was in a forest setting of pine and aspen trees with a thick underbrush. G Natural and cultural features: The property is located within the Timber Springs Subdivision, a residential subdivision in a gated community, above US Highway 6, Interstate 70 and Eagle River, west of Edwards, Eagle County, Colorado.
