This OWTS major repair permit was approved to completely replace the existing system (permit 1791- 98IS) and serve a total of four (4) bedrooms. The system installed under permit 1791-98IS was abandoned and that permit will be closed. Additional information about the maintenance your septic system needs can be accessed through our website links, provided on the Environmental Health Department’s septic system resource page. Be aware that changes in the use of your property or alterations of your building may require commensurate changes to, or relocation of, your septic system. Landscape features, trees with tap roots, irrigation systems and parking areas above the soil treatment area can cause premature system failure. It is equally important that you notice and im mediately repair dripping faucets and hissing toilets as this will certainly cause the system to fail. If you have any questions regarding this information, please contact us at (970) 328 -8755 and reference the OWTS septic permit number.

G 208 Eagle Crest Drive, Eagle County, Colorado G Lot 35, Block 6, Lake Creek Meadows, Eagle County, Colorado. G There is an existing, 4-bedroom residence G The water service is supplied by Lake Creek Metro. No well on the property. G We requested information on data for the existing septic system and received a reply that there was no data. G The topography of the leachfield site is moderate with an average slope of about 18 percent. G The profile hole was observed on August 14, 2019. The soil exposed in the profile hole was as follows: Profile Hole #1 0 to 20 inches Topsoil and blocky clay with roots 20 inches to 4 feet Reddish-brown, sandy, clay with some gravel 4 feet to 8 feet Reddish-brown, clayey, sandy gravel with some cobbles and boulders No ground water encountered A soil sample taken from Profile Hole # 1 at 36-inches, was classified as Type 4, Clay A second sample was taken from the underlaying soil at 8 feet. The lower soil was Sandy Clay Loam, Type 3, classified as Type R-1, Option 1 with >35% Rock > 2mm. REQUIRES: 2 feet deep, Unlined Sand Filter with Pressure Distribution LTAR = 0.8 gpd/sf G ! G The proposed leachfield site will be located in the Back /Side Position west of the existing residence and west from the existing leachfield. G The topography of the proposed leachfield site is moderate and the infiltrator chambers will be installed in trenches running along the contours. G The vegetation within the proposed leachfield site consisted of native grass. The site surrounding the leachfield was similar. G The lot is on a ridge. West Lake Creek runs about 350 to 400 feet to the west and about 50 feet below the STA site, at the bottom of the ridge. G The current use is residential. We understand that previously the use was agricultural. ! G G ! G This site evaluation was completed by Luiza Petrovska, PE, of LKP Engineering, Inc. LKP Engineering, Inc., is located at 67 Robins Egg Lane, Eagle, Colorado. The phone number is 970-390-0307 and Luiza=s email is luiza@lkpeng.com G August 14, 2019. G Attached G There is no well on the property. From the water service line to the proposed new STA (Soil Treatment Area or leachfield) there is over 25 feet. From the STA to the new septic tank it is about 10 feet, STA to building about 70 feet, STA to property lines greater than 10 feet, septic tank to building about 63 feet. G : Items 1-4, observed. G # # # # # # # G Temporary ccess road for the installation of the new septic tank will be required. G None known G There were no difficulties encountered during the site evaluation.

I received a call from the installer with the information needed to issue a final letter, he confirmed that after measuring, the water line is 31 feet from the soil treatment area, greater than 25 foot setback required. Please keep the attached information for your records. Eagle County Environmental Health will maintain a copy of your records under the permit number, parcel, and address listed in the letter. Please be aware that tanks should be pumped and cleaned every 3-5 years as necessary; and that submitting your pumping reports to our department will allow us to maintain a record of maintenance and good standing for any future inquiries or real estate transaction. Thank you, Claire Lewandowski -- Please note that beginning July 15 the Community Development Department will have new walk-in hours. The office welcomes walk-in customers between 8 a.m. and 4 p.m. Monday through Friday, except holidays.
