RE: Sopris RV Park

Dear Mark:

Enclosed are Individual Sewage Disposal System permit applications for the Sopris RV Park Leach Fields A and B. The design flow for each leach field is based upon actual flows measured at the Sopris RV Park from October 25 to November 22, 1994. The total average daily flow measured was 2,132 gallons per day (gpd). The total design flow for the two leach fields is 4,238 gpd as-outlined in the enclosed design calculations.

Leach Field A is a proposed leach field to be located near the entrance at the west end of the Sopris RV Park. This leach field will replace the existing leach field located adjacent to the Manager's residence. The existing septic tanks and dosing tanks for this system will be utilized. This system will serve RV Spaces 1 • 21 and the Manager's Residence; up to 4 bedrooms were allowed in the Manager's Residence to allow for future expansion of this residence. The average flow into this system at full occupancy is estimated to be 1,475 gpd; the design flow is 2,213 gpd. The proposed leach field consists of 62 "Biodiffuser" leach field chambers as shown on the enclosed design drawing and specifications. The required setbacks include 147 feet from the irrigation ditch, 197 feet from the water supply well and 379 feet from Leach Field B.

Leach Field B is an existing sewage disposal system located at the east end of the Sopris RV Park. This leach field serves RV Spaces 22 · 27, the laundry and the shower facilities. The average flow into this system at full occupancy is estimated to be 1,350 gpd; the design flow is 2,025 gpd. The existing system consists of two septic tanks and a 2,400 square foot leach field. The required size for this leach field is 1,400 square feet. The required setbacks include 132 feet from the irrigation ditch, 182 feet from the water supply well and 379 feet from Leach Field A. The existing septic tanks and leach field are sufficient as constructed; no improvements to the existing Leach Field B system are proposed.

302 Efghth Street, Suite 325 P.O. Orewer 160 Glenwood Springs, Colorado 81602 (303) 945·2236

Mr.' Mark Bean Page· 2

Both leach field systems meet the required setbacks from the irrigation ditch and from the water supply well. The two leach field systems also meet the State's separation requirements to be considered individual systems under the County's jurisdiction. Construction of Leach Field A will commence upon issuance of the ISDS Permit. Please give me a call is you have any questions or require additional information.

Sincerely,
