R91W; located approximately one (1) mile north of the Town of New Castle. SITE DATA: 18.2 acres WATER: Town of New Castle SEWER: I.S.D.S. ACCESS: County Road 245 EXISTING ZONING: A/R/RD ADJACENT ZONING: A/R/RD, R-MH/G/UD RELATIONSHIP TO THE COMPREHENSIVE PLAN The subject property is located in District A, New Castle Urban Area of Influence as shown on the Garfield County Comprehensive Plan Management Districts Map. H. DESCRIPTION OF THE PROPOSAL A. Site Description: The property is adjacent to the south side of the Elk Creek and Three Elk Run subdivisions. The property slopes from the north to south, with slopes in the lower third of the property adjacent to CR 245 ranging in grade from 15% to over 40%. The upper section of the property has slopes that are gentler, with a range between 5% to 30%, and an average of 10% to 15%. The predominant vegetation is pinion and juniper trees, with wheatgrass and sagebrush the main ground cover. B. Project Description: It is proposed to create 10 residential lots ranging in size from 1.1 to 1.4 acres in size, with 4.7 acres of common open space. The lots will have water supplied by the Town of New Castle. Sewage will be treated by the use of individual sewage disposal systems. Access will be provided from County Road 245 via a 40 ft. wide access and utility easement that ends in a cul-de-sac with a 70 ft radius. The proposed design of the subdivision is attached on page 411116 • • C. Background: The applicants had previously submitted a sketch plan for the project which proposed a conventional subdivision of 8 single-family lots of approximately 2.5 acres each. Based on comments from the Planning Commission, the applicants have decreased lot size to approximately 1.1 to 1.4 acres per DU, and requested PUD zoning, which was approved by both the Planning Commission and the Board of County Commissioners. A copy of the zoning text is attached on pages /01/ H. REVIEW AGENCY COMMENTS A. Town of New Castle: The Town has reviewed the project, and has granted 10 (ten) total taps for domestic water service (see letter on page /2 ). B. Division of Wildlife: A he time of PUD submittal, the DOW endorsed the project (see letter on pages / r . The Division commented on the sketch plan submittal, and recommended that dog restrictions be placed on the project (see letter on page _ /3 ). The applicant has included language regarding dog restrictions in the covenants (see Section 11 on page /5 ). In addition, the applicant is proposing perimeter fencing restrictions (see Section 10, attached ). Staff notes that the covenants have no enforcement mechanism (fines, etc..) within the covenants to enforce the dog restrictions. C. State Geologist: The State Geologist has not responded to the application, although Nicholas Lampiris, Ph.D., has reviewed the site for geologic concerns. The site has soils with development limitations due to shrink -swell potential and steep slopes. He suggests that all lots should have a " soils investigation for proper foundation design" and that the soils engineer needs to address how close a foundation can be to steeper slopes. The SCS soils information indicated that there may be ISDS limitations due to soils and slopes. The applicant's geologist noted that there should not be any problems for ISD systems, except in areas of steep slopes (See report pages/4'2Z). SGM has also provided additional ' formation regarding the feasibility of ISDS on the site (see letter on pages 23.24 III. STAFF COMMENTS A. Compliance with Comprehensive Plan. The project is in clear compliance with the following portions of the 1984 Comprehensive Plan: 1. Recreation and Open Space. Objective 2 which supports the creation of Open Space areas that will remain natural in perpetuity, particularly the transportation corridors between communities. 2. Water andSewerServices. Objective 2 encourages development located adjacent to existing subdivisions or municipalities with available capacity in their central water and/or sewer services to become a part of the existing system. Policy 2 requires that areas where a logical and economic extension of sewer lines can occur enter into appropriate agreements to receive service. 3. Environment Objective 1 discourages development of areas with severe environmental constraints. The proposed Open Space area is considered to have server constraints due to slope. • • B. Road/Access: The road is proposed to have a maximum grade of 10% (see attached road profile). A roadway serving ten (10) lots is classified as a semi -primitive roadway and is required to have at a minimum of a 40 ft. ROW, with eight (8) ft. driving lanes and two (2) ft. shoulders and a gravel driving surface. The proposed roadway centerline is the common lot lines of the proposed lots. This roadway will have to be dedicated to the public for use, but it will be maintained by a homeowners association. Cul-de-sacs may be permitted, provided they are not over 600 ft. in length. The proposed cul-de-sac is approximately 1500 ft. long. The Board may approve longer cul- de-sacs " for topographical reasons and it can be proved that fire protection and emergency egress and access is provided as a part of the longer design." The applicant has a favorable recommendation from the Burning Mountain Fire District (see page swz), C. Fire Protection: Favorable comment has been received from the Burning Mountain Fire Protection District. The Colorado State Forest Service noted some concerns about the adjacent Three Elk Run development, due to wild fire potential create by steep slopes. No response has been received from the Forest Service. Generally the State Forest Service feels wildfire problems can be minimized by following the recommendations for construction of homes contained in the CSFS publication "Wildfire Protection in the Wildland Urban Interface" and "Model Regulations for protecting People and Homes in Subdivisions and Developments". D. Drainage and Utilities: The project's engineer Jeff imonson) has addressed drainage and utilities on the site (see letter on pages '2 . Water will be provided by the Town of New Castle from an existing main at CR 245. Adequate easements are shown on the plat to provide service to each lot. ISDS would be used on each lot, and percolation tests indicate that standard systems are feasible on each lot. There is no evidence of high groundwater or shallow depths to bedrock. Electricity is currently provided by Public Service, and there is an existing overhead line along CR 245. Service would be provide to each lot from that source, and staff would suggest that all utilities on the site be underground. Public Service also provides natural gas to the area, and a transmission line is located in CR 245. This would also provide a source to bring gas service to each lot. US West provides phone service along CR 245, which would be extended to each lot. Drainage is intended to be controlled along the road with road side borrow ditches, and culverts if necessary. In short, the natural drainage patterns on the site will be maintained. The Coryell Ditch traversed the property, and a 20 foot setback is shown on the plan. A culvert will be required to cross the ditch with the primary access road. At the intersection of access road and CR 245, drainage would directed from the borrow ditches to the adjacent culverts already used by adjacent culverts utilized by the property. E. Natural Hazards. No mapped floodplain exist on the site, nor is the site tributary to avalanche or landslide areas. A review indicated that the property is not located within major slope, soil or ISDS hazards. • • IV. SUGGESTED FINDINGS 1. That proper publication and public notice was provided as required by law for the hearing before the Planning Commission 2. 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 the hearing. 3.

It is quite apparent that the Jolley's have given considerable thought and concern to the wildlife requirements and their future within the project boundaries. Our job is made much easier when we review covenants such as theirs and these covenants would be excellent examples for countywide standards. The DOW approves of this sketch plan and we see no major impact on wildlife or critical habitat as this plan is submitted. Thank you for sending me this sketch plan.

We have experienced severe problems here with dogs chasing wildlife and my request would be the requirement of kennels or yard fences that would retain dogs. In addition, the future landowners must know that the Division of Wildlife is not liable for damage caused by wildlife to gardens, lawns, or ornamental flowers and trees. I would also ask that any livestock owners within this subdivision be responsible for providing fence to protect their haystacks. Once again I would like to thank you.

This letter is intended to meet the submittal requirements of Section 4.08.05.(7).(e) of the Garfield County Land Use Code. This section of the code requires the statement by a licensed engineer providing evidence of the following: (i) The proposed water source adequate to serve the PUD (ii) The proposed method of sewage treatment (iii) The general manner in which the drainage will be handled (iv) The general manner in which provision will be made for any potential natural hazards in the area, such as avalanche areas, landslide areas, floodplain areas and unstable soils. The water for domestic use will be provided to each site by a community water system or water main extended from the existing main in County Road 245. The existing main is owned and maintained by the Town of New Castle. Prior correspondence from the Town of New Castle indicates the Town's intent to provide water service to this subdivision. Wastewater treatment for the subdivision will be treated individually for each lot with on-site Individual Sewage Disposal Systems. Based upon preliminary perc tests results, we anticipate that no unusual conditions exist that would prohibit the use of on-site sewage disposal systems. We anticipate that with the preliminary percolation rates being at 30 minutes per inch, the on-site systems would require standard construction outlined in the County Individual Sewage Disposal System Requirements. An area of 750 to 1000 square feet is anticipated also. There is no evidence of high ground water nor shallow depths to bedrock that we anticipate would require engineered Individual Sewage Disposal Systems. Obviously, the County requires (per State requirements) that a site specific percolation test be performed at the location of the proposed field installation when an individual unit or lot is developed. Electric service for this area is currently provided by Public Service Company of Colorado. There is an existing overhead line located along County Road 245 running parallel to the south property line of the project. Therefore, we anticipate tying into this line and extending service into the subdivision from County Road 245. Public Service Company of Colorado is also the natural gas supplier for this area. Again, they have an existing transmission line located in County Road 245 along the south property line of the project. Again, we anticipate extending service from County Road 245 into the project. U.S. West provides telephone service to residents in this area. Again, U.S. West has a main line located in County Road 245. We anticipate extending service from this main line into the project. • • March 27, 1994 Mr. Kent Jolly Page 2 Finally, TCI Cablevision provides cable r.elevision service to residents in this area. They have an overhead distribution line located along County Road 245 and we anticipate extending service from County Road 245 into the project. The project is intended to be served by a single 20 foot wide access, accessing from County Road 245 into the project ending at a cul-de-sac. The cul-de-sac will be of sufficient diameter to allow accessibility for emergency vehicles. This 20 foot wide access will be the only item that will provide an interruption to the existing drainage patterns. Generally, the patterns provide for sheet flow from a north to south direction across the site. The upper bench of the site consists of an intermixed disbursement of dense Juniper and Pinon with sage brush and native grasses. Along the south edge of the property and the west edge of the property, the slopes become steeper and will most likely be utilized as open space. Minor drainage paths are seen to traverse the site but do not constitute any major drainage flows. Drainage is intended to be controlled along the road with road side borrow ditches and with culverting as necessary. To the furthest extent possible, the natural drainage patterns will be accommodated. Along the upper (or off site) portion of the property, an irrigation ditch which serves Castle Valley Ranch exists to intercept drainage and direct it easterly of the property. Accordingly, along the southern portion of the upper bench, another drainage ditch which also serves Castle Valley Ranch traverses the site from west to east. Other than providing culverting to cross this irrigation ditch, no special features of construction will be required. At the intersection of the access road to the project and County Road 245, it is intended to direct drainage from the borrow ditches to the adjacent culverts already utilized by this property for transmission of runoff past County Road 245. At that point, all drainage will be re-established to its natural condition. Finally, no mapped floodplains exist on site nor is the site tributary to avalanche or landslide areas. We understand that you have rendered the services of a Geologist to further expand discussions on these natural hazards. Upon your receipt of this report, if you have any questions or comments, please don't hesitate to call. Sincerely, SCHMUESER GORDON MEYER, INC. 1 Je f; j y •J Simonson, P.E.
