CHURCH & Associates, Inc. ENGINEERS & GEOLOGISTS Subject OWS Design, Proposed Residence Lot 38, Westbank Mesa Development Garfield County, Colorado Job No. 16782 Mr. McIntyre, As requested, we have designed an onsite wastewater system (OWS) for the proposed residence. CTUThompson, Inc. performed the subsurface investip_ation on September 14, 1994. SITE CONDITIONS The lot is located in a rural residential area in Garfield County, Colorado, where OWS are required. The proposed drain field area has a 15% slope to the northeast and a moderate cover of native grasses, and weeds. Water will be provided to the residence by a well, located 100+- feet from the proposed field area. PROPOSED CONSTRUCTION A four-bedroom residence is proposed as indicated on Figure 1 In accordance with the Individual Sewage Disposal System (ISDS) regulations, the average sewage loading for a four-bedroom residence is 600 Gallons Per Day (GPD) and 900 GPD with a 1.5 peaking tactor. This loading includes a dishwasher, gar- bage grinder, and washing machine. If additional bedrooms in unfinished areas are possible, it is suggested the OWS be constructed to serve the added loading. The installation of an engineered OWS to serve future build -out can be cost effective SUBSURFACE CONDITIONS CTL/Thompson, Inc performed the subsurface investigation by drilling three percolation holes, 40 to 42 inches deep and two test holes at the locations indicated on Figure 2. Subsurface materials reported in Test Hole 38A cor.sisted•of 6 inches of organic, sandy clay underlain by stiff to very stiff, sandy clay to the maximum depth explored of 15 feet. Subsmntace materials reported in Test Hole 38B consisted of 6 inches of organic, sandy clay underlain by stiff to very stiff sandy clay to the maximum depth explored of 19 5 feet No ground water or bedrock was encountered. Percolation tests indicate percolation rates of 12 to 20 minutes per inch (NIPTy The average percolation rate is 15 MMPI. A percolation rate of 20 MPI wi l be used for this design. Percolation data is presented in Table 1 RECOMMENDATIONS The installation must include a septic tank, an effluent filter, and a gravelless chamber -trench drain field at the locations presented on Figure 2. The OWS design is based on an average sewage Toad of 600 GPD and a percolation rate of 20 MPI. The installation must include a 1250 -gallon, two -corn - DENVER 4501 Wadsworth Boulevard Wheat Rldge, CO 80033 in, ear 6111 Fir 9K!

The trenches may be modified to conform to topography and to preserve as int:ch vegetation as possible. A concrete distribution box is required to distribute effluent to the field Movement over the drain field area during construction should be kept at a minimum to minimize compaction of the receiving soils. The bottom of each trench must be scarified with a pick, shovel, or backhoe bucket teeth prior to the addition of chambers [he surface of the drain field should be seeded after installation of the system. A native seed mix from the area available at seed stores should he used These mixes do not require irrigation and develop a growth 10 to 15 inches high. No automatic sprinkler system should be installed over the field OPERATION ANI) MALNTEHANCE The owner must realize an OWS is different from public sewer sen'ice ane must assume the responsibility for maintenance of the OWS. The system is relatively maintenance free, but the owner must have the septic tanks pumped. in the absence of a monitoring program. the septic tank should be pumped and the effluent filter cleaned every two years. There are daily considerations, such as not putting plastic or other nonhiode- grada'.'le material into the OWS. Water use must be monitored so toilets are not allowed to run when seals malfunction To illustrate the point, a running toilet can consume in excess of 1000 GPD. A loading of 1000 GPD could flood and irreparably harm the OWS The loading from the back -wash of a water softener may be hartfiil to the OWS. A separate drywell should he constructed fbr the backwash waste, if a softener is installed. Chemically treated water from a swimming pool or spas should not be introduced to the OW'S. LIMITATIONS An OWS design requires installation by a licensed contractor- Our investigation, layout, design and recom- mendations are based on data submitted if conditions different from those described in this report arc encountered, we should be notified to evaluate the effect on the proposed ()WS. If the health department modifies this design we should he contacted to evaluate the impact on the performance of the OWS. All construction is to he in accordance with the ISDS regulations. Pipe type and size, burial requirements, septic tank construction and other specifications, wh)ch are not depicted in our report, are to conform to the requirements of the 1SDS regulations The installer of the system is to have demonstrated knowledge of the ISDS regulations and requirements if there are questions or if we can be of further service, please c.ait CI -II TRCH & Associates Inc.

Thompson Construction 720 East Cooper Avenue Glenwood Springs, Colorado 81601 Subject: Soils and Foundation Summary Report Lot 38 Westbank Mesa Development Garfield County, Colorado Job No. GS -1359 Gentlemen: This letter presents a brief summary of our foundation recommendations for the above referenced lot. This summary is provided for information and is not intended for foundation engineering purposes. Field and laboratory data and specific criteria developed for foundation recommendations are presented in our report dated September 19;1994 The soils encountered in the test hole on !Ks lot consisted of 0.5 feet of organic, sandy clays underlain by 14.5 feet of sandy clays. No free groundwater was encountered. We recommend construction of the proposed residence on a spread footing foundation. Footings should be designed for a maximum allowable soil pressure of 3000 psf and be at least 16 inches in width. isolated pads should be at least 24 inches square. Exterior footings should be protected from frost action with at least 3 feet of cover. The soils encountered exhibited no swell potential. Slab -on -grade construction involves a low risk of heave and cracking. We recommend the foliowina precautions for slab -on -grade construction: 1. Slabs should be constructed directly on the soils. Provision of a sand or gravel layer increases the possibility of a single source of water wetting the entire area supporting the slab. 2. Slabs should be separated from exterior walls and interior bearing members with a jo:nt which allows free vertical movement of the slab. 3. Slab -bearing partitions should be minimized. Where such partitions are required, a slip joint should be constructed to allow free vertical movement of the slab. north and west w:th the exception of sleeper grades that occur adjacent to the lower pal of Huebinger Road. Vegetation is sage, oik brush, juniper trees and native grasses and weeds. a large lot no'.n and northeast of the upper part of Huebinger Drive. Ground surfaces slope down Ft .tpprcx'rnate'y 20 to 30 percent from Huebinger Drive to a comparatively flat area with siopes of less than 5 percent to the north Steeper grades occur ur• the side of ravines that are an noilh and west parts of the lot.

Lots 60 61 and 62 These 'cis are located on the lower bench of the ?iesthank Mesa development. Buildings are planned on the to:, -?r parts of the lots. The upper ,arts are very steep and residertiai construction is no: feas.:'!e from a construcabii;ty viewpoint. The slopes range from 60 to 90 percent on upper ports, 25 to 50 percert on middle slopes and 10 to 30 percent on lower scopes. We recommend no building on slop•'s greater than 30 percent or these lots. The vegetation is sage. native grasses ani weeds Severn! rock outcrops are apparent cn the middle and upper slopes.
