LOCATION: A parcel of land situated in the SW 1/4 of Section 12 and the N 1/2 of Section 13, T7S, R88W of the 6th P.M.; located approximately four (4) miles north of Highway 82 on C.R. 103 (Crystal Springs Road) across from the Hawk Ridge Subdivision. SITE DATA: The site consists of 105.5 acres. WATER: Individual wells. SEWER: Individual Sewage Disposal Systems. ACCESS: Proposed private access road off C.R. 103. EXISTING ZONING: A/R/RD ADJACENT ZONING: A/R/RD I. RELATIONSHIP TO THE COMPREHENSIVE PLAN The site is located in District C - Rural Areas with Minor Environmental Constraints as designated on the Comprehensive Plan Management District's map. II. DESCRIPTION OF THE PROPERTY A. Site Description: The property is located in a rural area of the County, with uses in the vicinity being single family residential and ranching. The property consists of a north -south trending valley and its side slopes. The property drains from south to north in an intermittent channel. The valley floor consists of grasslands and irrigated pasture. The side slopes are vegetated with scattered pinon/juniper and oak trees. At the north end of the property is a single family residence and an enclosed riding arena. B. Project Description: The applicant proposes to divide the 105 acre tract into 7 single family lots ranging in size from 4.4 to 17.6 acres in size. The 8th lot of 46 acres would be retained by the owner for grazing and pasture purposes. C. Background: In 1982, the applicants submitted a Sketch Plan for Cedar Ridge Farm. At that time, the submittal was reviewed by the Planning Commission and the Board of County Commissioners (see enclosed staff comments, [pages ]) . No major objections were voiced at that time to the submittal. The current Preliminary Plan submittal is similar in design to the approved Sketch Plan reviewed in 1982. • • III. REVIEW AGENCY COMMENTS A. Colorado Geological Survey: No major geological impediments exist in this area. Major concerns are foundation design, adequate grading and drainage and radon mitigation (see letter on page ). B. Mt. Sopris Soil Conservation District: Their concerns include preservation of existing irrigated lands, soil erosion and adequate dog control (See letter on page C. Colorado Division of Water Resources: Requested that plat notes and protective covenants be developed consistent with water augmentation plan limitations. Noted that the water report by Dean Gordon indicated hard water. (See letter pages D. Colorado Department of Health: Notice that ISD systems must meet county and state requirements. IV. MAJOR ISSUES AND CONCERNS A. Design: Six (6) of the 8 proposed lots are located on the hillside slopes above the valley floor. Slopes on these lots, particularly Lots 1-4, range upwards to 25%. These slopes may present difficulty for wastewater and foundation design as well as requiring substantial excavation, Lots 7 and 8 are located on gentler terrain in the valley floor. Vegetation removal for homesite development should be minimal with the exception of Lots 2 and 3 where substantial amounts of pinyon/juniper oak scrub exist. B. Roads: The applicants are proposing to extend an internal roadway from C.R. 103 into a "K" turn -around adjacent to Lots 1 and 2. This roadway will consist of a 24 foot wide platform with 10' travel lanes and 2' shoulders within a 50' right-of-way. The proposed surface is gravel. There is currently an existing roadway within this alignment varying in width from 16 to 20 feet. From the "K" turn -around, a lesser width road right-of-way will extend to Lots 6 and 7. (See enclosed map on page Section 9:34 of the Subdivision Regulations state that private roadways may be permitted provided they meet all requirements of the regulations including design stand- ards. Minimum standards for this type road include a 28' driving surface width (includes minimum 2' shoulders) and a chip and seal surfacing treatment. Section 9:34 allows cul-de-sacs in excess of 600' in length if acceptable for fire protection purposes. A minimum cul-de-sac turn -around radius of 50' is required. No provisions for "K" turn-arounds are included in the Subdivision Regulations. In addition, contributions (ie. chip and seal surfacing) towards the upgrading of C.R. 103 may also be required. Specific contributions will be determined at a later date. f„ Y�. Water: The applicants are proposing individual wells on each of the proposed lots. Two potential groundwater re- sources exist in the vicinity, in the shall alluvial deposits and in the underlying basalts. Typically, the basaltic deposits yield higher quality and more reliable water. The existing well on Lot 7 is in bedrock at a depth of 186' and produces upwards of 50 g.p.m. Typical yields would probably be 5 to 25 g.p.m. The applicants have approved water rights and an augmentation plan for the construction of 7 wells. This plan provides .03 CFS for domestic in-house use, lawn and garden irrigation, stock watering and fire protection. The property is traversed by an irrigation ditch which waters the irrigated pasture land. It is unknown whether the applicant intends to transfer any of these rights to future lot owners. E. Wastewater: The applicants are purporting that septic tank/leachfield system will suffice for wastewater dis- posal purposes. I.S.D.S. systems are currently in place on Lots 6 and 7 serving the existing residence and riding arena. S.C.S. soil survey data indicates that there may be severe limitations for septic tank/absorption fields due to the steep slopes and presence of large stones. F. Fire Protection: The subject property is located within the Carbondale and Rural Fire Protection District. No response from the District has been received to date. The applicants are proposing a 5000 gallon cistern for fire fighting supply. G. Drainage: Stormwater runoff will be collected through a series of existing culverts and routed through natural drainage courses. Runoff will leave the property heading northward concentrated into an intermitted stream bed. No significant increase in stormwater runoff should be generated by the development proposal. H. Wildlife: No response has been received from the Division of Wildlife regarding impacts of wildlife. Covenants will restrict the number of dogs and require that they be kenneled to reduce potential for conflicts with wintering deer and elk. I. Utilities: The applicants are proposing to place underground electric service within the 50' road right- of-way. No reference to telephone service has been indicated in the application. V. SUGGESTED FINDINGS A. That proper publication, public notice and posting were provided as required by law for the hearing before the Planning Commission; and B. That the hearing before the Planning Commission was extensive and complete, that all pertinent facts, matters and issues were submitted and that all interested parties were heard at that hearing; and C. That the proposed subdivision of land is in general compliance with the recommendations set forth in the Comprehensive Plan for the unincorporated area of the County; and D. That the proposed subdivision of land conforms to the Garfield County Zoning Resolution; and E. That all data, surveys, analyses, studies, plans and designs as are required by the State of Colorado and Garfield County have been submitted and, in addition, have been found to meet all requirements of the Garfield County Subdivision Regulations. VII. RECOMMENDATION On September 12, 1990, the Planning Commission recom- mended APPROVAL, subject to the following conditions: 1. That all representations of the applicant, either within • • the application or stated at the public hearing before the Planning Commission shall be considered conditions of approval, unless otherwise stated by the Planning Commission. 2.

Rd) Site Data: The parcel is a 102 acre parcel of gently rollinr topography located above Cattle Creek to the north. Water: Proposed from individual wells on each lot. Sewer: Individual septic systems on each lot. Existing Zoning: A/R/RD (Agricultural, Residential, Rural Density) Adjacent Zoning: North: A/R/RD South: A/R/RD East: A/R/RD West: A/R/RD Adjacent Land Uses: North: Steep terrain to Cattle Creek South: Agricultural East: Agricultural West: Agricultural Relationship to the Comprehensive Plan: This parcel is located in Management District C, a rural area with minor enviromental constraints -Page 70 of the Comprehensive Plan. These lands have moderate suitability to absorb growth. Non-agricultural and non-productive cropland shall be considered best able to absorb growth. Road access and condition shall be used to evaluate the relative ability of areas within District C to absorb growth. District C shall be considered to have a maximum density of one unit per 5 acres. Any development in District C which is determined to have a high degree of visual impact shall receive special attention to building siting, etc. Description of Proposal: A) The site is located on agricultural land which seems to be phasing out of production. The site is primarily vegetated with clusters of oak, juniper, and pinion with irrioated areas of hay. The site is gently rolling and slopes to the north toward Cattle Creek. B) The project consists of 7 single family lots ranging in size from 5 acres to 17 acres. There is proposed an 8th lot of 46 acres to be used and maintained as pasture land for horses. Major Concerns and Issues: A) The applicant is proposing that the existing dirt road into the property be retained "as is" as a private road. It is against county policy to allow private roads and it is inappropriate to allow subdivisions to have access off substandard internal access streets: B) The applicant is also proposing individual wells on each lot as opposed to a central water system. The commission should pay special attention to this request because the county has not approved, in recent times, any subdivisions over 6 lots on individual wells. Individual wells, each with a plan for augmentation, do not represent, in the staff's opinion, a major prohlem to water supply for the subdivision. c) Fire protection is a major issue for the subdivision. The applicant proposes individual 1,000 gallon cisterns on each lot. No comment has been received from the Carbondale Fire Department regarding cisterns of this size, but should be available by the Planning Cori i ss ion meeting. D) Hawk Ridge Subdivision has been required to chip and seal County Road 103 from the existing paved portion to their project. Cedar Ridge Subdivision should be required to extend the paving to their access. Cedar Ridge and Hawk Ridge Subdivision should be required to share in the costs of improvements to County Road 103 on a per/lot basis. E) The preliminary soils report indicates that there may be potential limitations for septic systems because of soils. Individual perk tests should be preformed on each lot to determine whether standard or engineered septic systems will he required. V5/5/„.1 t\JA. i FINDINGS: This proposal seems compatible with the precedent which has been set for larger lot sizes in this part of Missouri Heights. The proposal also meets the basic provisions of the comprehensive plan. Therefore, the staff does not find any major objectives to this proposal. RECOMMENDATION: Approval with the following conditions: cAlo 1) That the major access road within the subdivision be constructed to county standards. 2) That the issue of fire protection be addressed in detail at preliminary plat and comply with the recommendations of the Carbondale Rural Fire District. 3) That Cedar Ridge Subdivision he required to extend the paved portion of 103 Road to their access and share in the costs of road improvements with Hawk Ridge Subdivision on a cost per/lot basis. 4) That perk tests be performed on each lot to determine whether standard or engineered septic systems will be necessary. 5)---- A Ouc6,, 4.c ^'-• oLo--� ,c.,,,re,c,o... ,ovr,0 i,_e_ .0-e,v)Ziz,t).wz 0 .A'Ai\-e'Q i21-2-- eCiz6L' „ Oeiffe4,v, _in . -Zt-d- ---gc Ap-A,0 A,(‘*,:,,S. . i i GA -91-0004 ROY R.

ROLD DIRECTOR _r �.Y r • l�Ur.:291990 i;( I RE: Cedar Ridge Farm Dear Mr. McGregory: We have reviewed the materials submitted regarding this proposal and the general and engineering geology of the area. Proper foundation design, adequate grading and drainage and radon mitigation are the critical issues in this area. The foundation design and grading/drainage recommendations found in the Chen/Northern and Lincoln DeVore reports should be followed. Structural design or HVAC systems should be modified to minimize the potential for radon gas accumulation in occupied buildings. If these conditions are met, we have no objections to the approval of this subdivision. Yours Very Truly, 0 (J (1 (1 Jeffrey L.

BOX 1302 GLENWOOD SPRINGS, COLORADO 81601 August 3, 1990 Garfield County Planning Department 109 8th Street, Suite 303 Glenwood Springs, CO 81601 Dear Andrew: J ir-r 171 1----N ruC a 1990 1_ At the regular monthly meeting of the Mount Sopris Soil Conservation District the Board reviewed the plans for Cedar Ridge Farm. Since they had reviewed a plan for this property in the past, they were very familiar with the property. Some of the concerns they did note were that although a table was shown using the SCS soil symbols, they felt that the complete information sheets on each of these soils are very helpful to those reviewing as well as the landowners. Since this service is provided without cost by the Soil Conservation Service, they would urge that the material be included in full in packets. Since irrigation is used on this land, the Board recommends that continued use of the ditch be preserved for homeowners' use, and any erosion the ditch may cause or have within the ditch be controlled as much as possible. As always, the Board is concerned about soil and water preservation, and encourages the use of measures that ensure water quality as well as control of soil erosion. With this area being one with wildlife populations, the Board recommends that strict control of animals, especially dogs, be maintained. Again, the Board appreciates being allowed to make comments on development within their boundaries.

DANIELSON State Engineer 1 ., 1 t !990 NTY i/ We have reviewed the above referenced submittal for a subdivision of 105.5 acres into seven residential lots. The proposed water supply source is individual wells. An augmentation plan (Case No. 81CW497) has been approved in Water Court. The seven proposed wells are each limited by the augmentation plan to single-family in -house -uses, non-commercial lawn and garden irrigation of up to 0.04 acres, fire protection, and the watering of livestock. Plat notes and protective convenants should be promulgated to limit water uses to those discussed above. The homeowner's association should have powers to enforce these restrictions. The water rights used to replace depletions from the wells in this subdivision should be conveyed to the homeowner's association. One individual should be designated to be specifically responsible for these water issues and his name and telephone number should be provided to our Division Engineer and Water Commissioner. A water supply report prepared by Mr. Dean W. Gordon was submitted indicating that there is sufficient physical supply to serve the development. This report also indicates that the water quality is satisfactory although it mentions that "typically ... the water from these wells tends to be classified as "hard" with respect to mineral content and high in dissolved solids." As long as the approval of this amended copy of the above issues are adequately addressed, we can recommend subdivision proposal. However, we would like to see an protective convenants prior to final platting. Sincerely, James R. Hall, P.E.
