Carter 201 West Third Street, Ste. 201 Rifle, CO 81650-0192 Garfield County RE: Grand Valley Fire Protection District - Rulison Site Dear Mr. Carter: Building & Planning Department After reviewing your letter regarding the purchase of a one-half acre site in the Rulison area for a fire substation, Don DeFord and I concurred with your determination that the property is exempt from the County Subdivision Regulations. However, there is a provision of the Colorado Revised Statutes that would apply to this purchase. Under the provision of §30-28-110 (1) (a), any public building or structure must be submitted to and approved by the County Planning Commission. Once the GVFPD has determined what type of structure they want to place on the property, a copy of a site plan and basic building plans needs to be submitted to the Planning Department. The site plan and building plan will be placed on the next Planning Commission agenda with time available, for their review and comment. If you have any questions about the process or question the applicability of the statute, feel free to call or write to Don DeFord or me, at your convenience. Sincerely, Mark L. Bean, Director Building & Planning Department xc: Don DeFord David Blair, GVFPD 109 8th Street, Suite 303 945-8212/285-7972 Glenwood Springs, Colorado 81601 CARTER & SANDS, Paco P.O.

Mahaffey, for the purpose of building a Rulison fire sub -station. Under the provisions of §32-1-1002(1)(b), the District possesses the power of Eminent Domain both within and without the special district. This property is located within the special district. Under the provisions of §30-28-101(10) (c) (II), this purchase is therefore exempted from the terms "subdivision" under the County subdivision regulations. We are currently dealing on another case involving that same statute, but as I read it, since this property could be acquired by eminent domain, even though it is being purchased at an arms length transaction, no formal submittal to the County is required, and the Commissioners need not grant any specific approval. However, the District wanted me to make certain that the County was aware of the proposed purchase, and that my understanding was correct. I'm sending a copy of this letter to Mark Bean so that he is aware of the purchase.

Car er SLC: dlh xc: David Blair, Grand Valley Fire Protection District Mark Bean, Garfield County Planner January 11, 2001 Phil Vaughan Construction Management, Inc. 1038 County Road 323 Rifle, CO 81650 RE: Rulison Station — Proposed ISDS System, Grand Valley Fire Protection District, Garfield County, Colorado SE Job No. 20047.01 Dear Phil: Pursuant to your request, attached herewith is a letter/report presenting our findings in regard to the design of an Individual Sewage Disposal System (ISDS) at the above referenced Site. This design is based on our evaluation of the site conditions with information provided by others for use in supporting your application to Garfield County. Our recommendations are in accordance with Garfield County and the State of Colorado ISDS Regulations. Garfield County must permit any proposed improvement to the site. We have reviewed the information forwarded to us, conducted a site visit, formulated an ISDS design and created a site plan with construction details as part of our scope of work. Conclusions: Based on our findings we believe that the design and installation of an approved ISDS system is feasible in accordance with the Regulations of Garfield County and the State of Colorado. We recommend that a new 500 gallon septic tank be installed that will discharge effluent to a 93 square foot soil absorption. trench system. The soil absorption system can be installed in natural soils. The system will meet all required setbacks and be installed within the general boundaries of the septic development envelope indicated on the plan. Our Design is outlined below and delineated on the attached site plan. Site Location: The subject site is located near the Colorado River and adjacent to County Road 309 in Garfield County, Colorado. The site is situated in Section 36, T 6 S, R 95 W of the 6th P.M. The Site comprises approximately 1.0 acre. The site is bounded on the West and East by undeveloped rangeland, on the north by County Road 309 and on the South by undeveloped land. Existing Site Conditions: The 1.0 acre site is located on a moderately sloping range land bench above the Colorado River. The land may have been irrigated with water from a ditch located east and south of the property. The site has a gentle slope toward the northwest. The existing ground surface in the proposed septic envelope is on moderately sloping ground with an approximate slope of 12%. The site is covered with grasses, sagebrush and has a greenbelt of spruce and cottonwood trees along the southern and eastern lot boundaries. Domestic water is supplied by an existing registered well, on the adjacent property to the southeast. No well information is available at this time. 502 Main Street • Suite A3 • Carbondale, CO 81623 • (970) 704-0311 • Fax (970) 704-0313 SOPRIS ENGINEERING • LLC civil consultants Phil Vaughan SE Job No. 20047.01 3/9/01 Page 2 Proposed Site Conditions: It is our understanding that you intend to construct a 4000 S.F., one story steel frame/metal skin structure, to be used as a volunteer fire station. The proposed improvements will include a new ISDS system to serve a single closet fixture and a wash basin. No kitchen or laundry facilities are proposed. The new facilities are to be generally located as shown on the plan. Subsurface Conditions: Attached herewith are the results of the subsurface investigation and percolation tests conducted on June 2, 2000 by Hepworth-Pawlak Geotechnical, Inc. The report is dated June 27, 2000, Job Number 199 893. The subsoil encountered at the site consists of feet of topsoil overlying medium stiff to stiff, sandy silty clay to the profile pit depths. Groundwater was not encountered to a depth of 8 feet in the test profile pits. Percolation testing utilized three test holes, which yielded similar absorption rates. The fastest measured rate was 24 minutes per inch and the slowest measured rate was 40 minutes per inch. The average percolation rate is 32 minutes per inch and is suitable for a conventional absorption system. Design Criteria: Proposed structure contains only two fixtures, a toilet and wash basin. No kitchen, bathing, laundry and boarding facilities are proposed. The design flow is calculated as follows: The design flow equivalent for a Volunteer fire station is assumed to be similar to a church or theater. We believe that a reasonable water usage value for this facility is 5 gpd per maximum number of firemen, which is assumed to be equivalent to a theater or church per seat. From the State of Colorado County I. S. D. S. Regulation; Average daily flow (Q) = # of people x 5 gal/person/day (avg. flow) Max. Design flow (Qd) = # of people x 5 gal/person/day x 1.5 (peaking factor) = gal/day Maximum number of Firefighters is assumed to be 10 people. Gallons per day for the subject facility = 5 gal/person/day Qd = 10*5*1.5 = 75 gal/day Septic Tank Design: Per regulations Qd = 10*5* 1.5 = 75 Volume (V) of tank = Design Flow * 1.25 (30 hour retention time) V = 75 gal/day * 1.25 = 94 Use one 500 -gallon septic tank If a 500 -gallon tank is not available use next available size. A single chamber tank is acceptable with an approved effluent filter vault. The tank must have appropriate access openings with risers and lids. Phil Vaughan SE Job No. 20047.01 3/9/01 Page 3 Percolation Test Results: Attached with this report are the percolation test results from Hepworth - Pawlak Geotechnical, Inc. dated June 27, 2000. The results of percolation tests indicated the average percolation rate of 32 minutes per inch is within acceptable ranges for conventional absorption systems as required by Garfield County regulations. The field is sized by using the standard absorption area equation and a long-term acceptance rate. A soil absorption trench disposal system is recommended. The maximum loading rate (MLR) for this system is 0.4 gallons per square foot per day based on the percolation rate. Soil Absorption System Design: Based upon the percolation test rates, the standard absorption area equation yields: A (SF) = Q *(t) '/ : where A = Area; Q = flow (gal/day) 5 t = time in minutes This design will give a recommended minimum absorption area: A = = 75 *(32) 1/2 = 85 sq. ft. 5 However Qd / A = 75 gal/day = 0.88ga1/sf/day 85 sf Therefore: A = Qd / MLR = 75 gal/day = 187 sf 0.4 gal/sf/day We recommend using a gravelless absorption trench system and reducing the area by 50%. Therefore: A = Qd / MLR x 0.5 = 75 gal/day x (0.5) = 94 sf 0.4 gal/sf/day We recommend using a trench system composed of 1 trench 39 feet long and 3 foot wide, containing 6 standard absorption chamber units. Use: Minimum 94 sf of absorption trench. An inspection port should be installed from the top of the pre -molded cut out at the midpoint of the terminal end chamber in the trench. This will allow for checking the performance of the system over time. Phil Vaughan SE Job No. 20047.01 3/9/01 Page 4 General Notes: 1) All materials and installation practices shall conform to Garfield County and the State of Colorado Individual Sewage Disposal Regulations. 2) All sewer lines and distribution lines in the system shall be 4" Schedule 40 or SDR -35 PVC unless specified otherwise on the plans. 3) Add a two-way clean out on the service line from the proposed Building. 4) The contractor shall ensure that the concrete septic tank and sewer lines are watertight. 5) The trench area must be protected to prevent damage from vehicular or livestock traffic and must be crowned to divert drainage runoff away from the bed. 6) The 6 absorption chambers shall be installed level in each trench, with a splash plate, placed on the surface in the first chamber below the inlet to prevent scouring from the effluent. 7) A final cover of soil suitable for vegetation, a minimum 10" deep, shall be placed to the finished surface grade. 8) The absorption trenches must be sodded or covered with vegetative ground cover. Our design and recommendations are based upon data supplied to us by others. If subsurface or site conditions are found to be different from those presented in this report, we should be notified to evaluate the effect it may have on the proposed ISDS. If the County Environmental Health Department requests changes or modifications to this design, we should be contacted to evaluate the effect on the ISDS. If you have any question or need any additional information, please call. Sincerely, SOPRIS ENGINEERING, LLC Paul E. Rutledge Design Engineer Yancy Nichol, P.E. Project Engineer
