A 285.08 acre parcel to be split into tracts of land that would allow a maximum of sixty three (63) single- family dwelling units and one residential fourplex (67 total dwelling units). Wells - Community System ISDS County Road 109 PUD I. RELATIONSHIP TO THE COMPREHENSIVE PLAN The proposed PUD is located District 1C -Central Water and Sewer, Severe Environmental Constraints as indicated on the Comprehensive Plan Management Districts Map. II. DESCRIPTION OF THE PROPOSAL A. Site Description: The proposed PUD is located on a bench overlooking the Roaring Fork river valley floor, directly above the existing Westbank development. Topography on the site consists of three distinct geologic configurations: a moderately sloping lowland fully vegetated with native grasses, a steeply sloped zone sparsely vegetated with evergreen species, sagebrush, and native grasses, and an upland benched area well vegetated with significant sagebrush, rabbitbrush, and isolated stands of pinion and juniper. Several intermittent drainages are visible in the steeper portions of the property and extend into the upland bench. Elevations on the property range from 5,950 at the northern edge, to almost 6,880 feet at the southern reaches of the property. A vicinity map is shown on the cover sheet of the plans submitted with the staff report. • • B. Background: Westbank Filing #4 was approved and platted in September of 1982. In April of 1993, the applicants proposed revisions to the 1982 approval, but withdrew the application based on comments from the Planning Commission. Table 1 summarizes the 1982 approval, the April 1993 submittal, and the current proposal. TABLE 1 COMPARISON BETWEEN APPROVED AND PROPOSED PROJECT Since that 1982 approval, the Subdivision Improvements Agreement (SIA) has been amended in respect to two dates: the deadline for improvements has been changed from November 1, 1984 to November 1, 1994; and the deadline for security for the improvements described in the SIA has been extended from July 1, 1983 to July 1, 1993. These amendments were made in response to a public meeting to consider the revocation of the approval of Filing ##4 in March of 1992, due to the failure to complete any of the required improvements on the site. Since the 1993 SIA security date has past, the Board has the authority to revoke the PUD, which would return the property to its underlying zoning (A/R/RD). No action has been taken by the Board at this time. C. Development Proposal: The current proposal includes 63 single-family lots and one multi -family fourplex for a total of 67 dwelling units. A zone district map and site plan are included in the staff packet. The approved plan anticipated an expansion of the existing water system which currently serves Westbank Filings 1, 2 and 3. The current proposal includes a separate system, with water to be provided from new well(s) to be augmented with Ruedi Reservoir water. A total of 40 acre feet of water is to be purchased from Ruedi for the needs of the development. Fire protection will be provided via hydrants and a storage system. No hydrant locations or infrastructure details are included with this submittal. 0 1982 APPROVAL APRIL 1993 SUBMITTAL CURRENT PROPOSAL Dwelling Type and Number- 10 four-plex lots, 10 duplex lots and 38 single- family lots (98 Total DUs) 98 single-family dwelling units 63 single-family dwelling units and 1 multi -family fourplex (67 total DUs) Lot Size 0.44 acres to 1.94 acres (36 of 58 less than 1 acre) 1.0 to 15.0 acres (0.344 DUs/acre) 1.0 to 14.26 acres (0.438 DUs/acre) Site Plan 81 DUs on upper bench and 17 on lower bench 91 DUs on upper bench and 7 on lower bench 51 DUs on upper bench and 17 on the lower bench Water Supply Expansion of existing system serving Westbank Filings I through III Separate central system augmented with Ruedi water Separate central system augmented with Ruedi water.

Colorado Geological Survey: The Colorado Geologic Survey has reviewed the project, and conducted fieldwork on July 13, 1993 (see letter on pag #1 . Based on their review, the areas of significant hazards have been avoided, although the "safe build" areas on lots 1, 2, 35 and 43 are relatively small. The Geologic Survey also "strongly concur with CTL/Thompson that each lot and building site be investigated by a qualified engineering geologist and/or soils and foundation engineer...". Costs regarding maintenance costs for the roads and infrastructure will be higher than typical subdivisions. The feasibility of ISDS was also questioned, and a central sewer was mentioned as a preferred alternative. In conclusion, Geologic Survey states that ..."the project is feasible, but only with careful planning down to the siting of homes on lots." A Reconnaissance Geologic Investigation (CTL/Thompson, Inc. June 24, 1993) is included as Exhibit G of the application. The primary conclusions from the CTL/Thompson report are as follows: • "Preliminary foundation recommendations and construction criteria can only be determined from more detailed, site specific surface and subsurface investigations and analysis" (p.1); • "Areas mapped as Qsl (Slide Deposits) on the site include medium to large slump features and failures of colluvial slopes. These areas appear fairly stable but will become unstable if disturbed" (p.6); • "None of the geologic conditions found are considered to be sufficiently hazardous to prevent development of the project as proposed, however, potentially hazardous geologic conditions must be properly planned for during site development" (p.7); • "We recommend that detailed, site specific soils and foundation investigations be performed for each residence built in this development" (p.7); • "Development in areas of potentially unstable slopes or immediately adjacent to steeper slopes along the lower edge of the upper terrace should be avoided" (p.8); • Drainage and ravines on the site present moderate potential hazard from flash flooding and low potential from debris flow. We recommend determining the 100 year flood plain (which will be a part of the site drainage plan) and avoid development in those areas" (p.9). B. Colorado Department of Health: Staff contacted Mr. Dwayne Watson, who concluded that the project was not located within a 201 planning area. No written comments have been received to date from the Colorado Department of Health. Based on Mr. Watson's conclusion, there are no statutory constraint to ISDS. C. Colorado State Forest Service: The Colorado State Forest Service reviewed the previous submittal, and conducted fieldwork on April 1, 1993. The proposed subdivision is in an area that has been mapped as medium to high hazard for wildfire. The Forest Service was particularly concerned with areas in the subdivision where grades exceed 30 percent and the densely vegetated drainages. Forest Service standards require dual ingress/egress points, which are not included in the proposal. The proposed cul-de-sac far exceed the 750 foot maximum length as recommended by Forest Service standards. Turnouts are recommended at 750 intervals to provide adequate emergency vehicle access. Mr. Roger's suggested that structures not be located in or at the head of drainages. A copy of Kelly Roger's April 7, 1993 letter included in the application as Exhibit I. D. Carbondale and Rural Fire Protection District. Ron Leach visited the site on April 29, 1993, and his comments are included in the application as Exhibit I. Mr. Leach concluded that the wildfire danger was "low", conflicting with the conclusions of the Forest Service. E. U.S. Bureau of Land Management: The BLM has submitted a letter dated July 30, 1993, reiterating their past comments (see letter on page S / . Primary concerns noted in their letter of April 2, 1993 included the following: 1. The BLM recommended fence standards that allow for easy passage by big game; 2. The parcel immediately adjacent to the site has been identified as a disposal parcel, and is not expected to remain in public ownership; 3. The density proposed by the applicant will render the critical mule deer habitat unsuitable for deer habitat, and will increase deer impacts on adjacent property, particularly during the winter months; 4. The soils on the site are poorly suited for housing development due to shallow depth to bedrock, steep slopes, and very high hazard of water erosion. A copy of Michael Mottice's April 2, 1993 letter is attached on page / 1 . F. Public Service Company: No response has been received from Public Service. G. Colorado Division of Wildlife: The Division of Wildlife has reviewed the proposal, and had the following comments (see July 27, 1993 and April 1, 1993 letter on pages 1) The area is considered to be elk winter range and critical deer habitat, meaning that the loss of critical winter habitat would adversely affect deer in the area. 2) DOW further states that big game populations in the area will be threatened by domestic dogs, loss of native vegetation, increased erosion, increased vehicular traffic, increased human/wildlife interaction, and migration obstacles. The DOW suggests the following mitigation: A) Reduce the density by cluster development; B) Require underground utilities to protect raptors; C) Require fencing restrictions; D) Restrict or prohibit domestic dogs and horses within the subdivision; E) Restrict building envelopes to preserve native vegetation. In addition, the DOW suggests that all homeowners are aware of the critical habitat designation, and realize that deer and elk will die on the property, and are responsible for disposing of carcasses. The July 27, 1993 correspondence from DOW, based on a review of the updated submittal, indicated that the Division stands by their previous comments. They also suggest that dogs be limited to 1 per dwelling unit, that physical kennels are more effective than the proposed electric fences, and offered additional fencing suggestions. • • In response to DOW concerns, the applicants have prepared dog restrictions, based on previously approved subdivisions in Garfield County. A copy of these proposed restrictions are included in the application, beginning on page 7. H. Roaring Fork School District RE -1: No Response. I. Office of the State Engineer, Division of Water Resources: The State Engineer's Office has reviewed the application, and had the following comments (see letter on pages 021 1) Prior to Final Plat, a court approved water plan must be decreed; 2) The protective covenants should include language concerning the management and responsibility of the wells and water system and define the amount of allowed irrigation. J. Public Service Company: No Response. K. Holy Cross Electric Association: No Response. L. U.S. West Communications: No Response. M. Rocky Mountain Natural Gas: No Response. IV. STAFF COMMENTS 1. Modification of PUDs. This application is requesting approval for a PUD amendment. Section 4.12 addresses the enforcement and modification of provisions of an approved PUD. Specifically, Section 4.12.03 requires the following: "All those provisions of the Plan authorized to be enforced by the County may be modified, removed or released by the County, subject to the following: (1) No modification, removal orrelease of the provisions ofthe Plan by the County shall affect the rights of the residents, occupants and owners of the PUD to maintain and enforce those provisions at law or in equity; and (2) No substantial modifications removal orrelease of the provisions ofthePlan shall be permitted except upon a finding of the County, followinga public bearings called and held in accordance with the provisions of Section 24-67-104, C.R.S., that the modification, removal or release is consistent with the efficient development and preservation ofthe entire PUD, does not affect inasubstantially adverse manner either the enjoyment of land abutting upon or across a street from the PUD, or the public interes4 and is not granted solely to confer a special benefit upon any person." At the Planning Commission hearing, testimony was given by adjacent owners in the existing Filings in opposition to the proposed PUD amendment. Specific concerns of adjacent property owners included the following: 1.) The impact on property values due to the loss of open space associated with the approved PUD. Testimony was given regarding the assurance that these owners had placed on the prior approval at the time of purchase; `Section 4.12 Enforcement and Modification of Provisions of the Plan, Garfield County Zoning Resolution_ 1984 as amended. 4- • • 2.) Due to the geologic and hydrologic characteristics of the property, adjacent owners voiced concern regarding the impact of drainage (see the geologic map on sheet 18 - Flashflood Hazard) on tracts located below the lower bench. It is expected that these concerns will be presented at the public hearing before the Board of County Commissioners. 2. PUD Objectives: Section 4.02 of the Subdivision Regulations establish the Purposes and Objectives of PUDs. These standards are taken directly from state statute, and are as follows: A PUD may be approved by the County Commissioners for the following purposes and to achieve the following objectives: 1. To provide necessary commercial, recreational, and educational facilities conveniently located to housing; 2 To provide well -located, dean, safe and pleasant industrial sites involving a minimum of strain on transportation facilities (NOT APPLICABLE); 3. To insure that theprovisions ofzoning laws which direct the uniform treatment of dwelling type, bulk, density, and open space within each zoning district will not beapplied to the improvement ofland byother than lot -by -lot development in a manner which would distort the objectives of the zoning laws; 4. To encourage innovations in residential, commercial and industrial development and renewal so that the growing demands of the population may be met by greater variety in type design, and layout of buildings and by the conservation and more efficient use of open space ancillary to said buildings; S. To encourage a more efficient use ofland and of public services, or private services in lieu thereof, and to reflect changes in technology of land development so that resulting economies may inure to the benefit of those needing homes; 6. To lessen the burden of traffic on streets and highways; 7. To conserve the value ofland; 8. To provide a procedure which can relate the type design, and layout of residential, commercial, and industrial development to the particular site, thereby encouraging preservation of the site's natural characteristic or 9. To encourage integrated planning in order to achieve the above purposes and objectives of development.' In the application, the applicant desire to modify several provisions of the approved PUD because the "it is felt that the density of lot of the original plan in keeping with development that has occurred in the general area (sic)".. and "the difficulty of permitting and constructing sewage treatment facilities which would discharge to the Roaring Fork River has caused the construction of central sewage collection system to be impractical. "3 2Section 4.02 Purposes and Objectives of Development, Garfield County Zoning Resolution, 1984 as amended. ?Westbank Ranch Planned Unit Developmen Modification and Westbank Ranch Filing #4 Subdivision, (Gamba and Associates) page 1. • • • • Significant discussion at the Planning Commission hearings centered on Objective #4, which addresses the innovation and variety in the physical design of the PUD. This point is relative to this decision due to the dramatic differences between the approved and proposed PUD. The approved project concentrates all development within the areas of the project with the least identified environmental constraints (maps of the approved PUD will be presented at the public hearing). In addition, open space provides a significant buffer between the existing Westbank Filings and Filing #4. Finally, the variety of housing types approved in 1982 is a much greater scale then currently being proposed (see Table 1). Staff notes that the financial feasibility of central sewer, or the project as a whole, is not a criteria recognized by either the Zoning Resolution, the Subdivision Regulations, or state statutes in evaluating a land use application. Staff will defer to the Board of County Commissioners regarding compliance with these objectives, based on a comparison with the approved project. 3. Consistency with the General Plait: Section 4.04 requires that "No PUD shall be approved unless it is found by the County Commissioners to be in general conformity with the County's General Plan". Comments regarding applicable portions of the Comprehensive Plan are as follows: Housing: The overall goal of the housing section of the Comprehensive Plan is as follows: Provide for affordable and diverse housing types capable of accommodating the needs of Countyresidents, in allincome ranges, without puttingafinancial burden on existing public serviaes.4 Objective #3 calls for the promotion of a variety of housing types and mix through the use of a flexible development review process. Policy #3 states that the PUD process is encouraged, so that the development community has greater flexibility in project design.' In staff's opinion, the cluster concept proposed in the 1982 approved project is consistent with the housing goals described earlier than the current application, although a single, four unit fourplex is included in the development. In addition, the applicants are proposing duplex lots as a conditional use. The duplex concept, although commendable, has some technical flaws, discussed in detail on page 9 of the Staff Report. Staff concedes that the concept of "affordability" is difficult to define, although the term "variety" is more applicable for comparative purposes. Recreation and Open Space: Policy 5 requires that areas such as floodplains and geological unstable soils which are restricted for the building of habitable structures will be used as common open space accessible to the public in new developments.6 The CTL/Thompson Report indicated that "Development in areas of potentially unstable slopes or immediately adjacent to steep slopes should be avoided".7 As shown 4Garfield County Comprehensive Plan, page 2. 5Garfield County Comprehensive Plan, page 2. 6Garfield County Comprehensive Plan, page 7. 'Reconnaissance Geologic Investigation, CTL/Thompson, Inc. June 24, 1993, page 8. • • on the Geologic Hazard Map, (Sheet 18), areas of unstable slopes are included within platted lots, and are not dedicated to the public. It does appear, however, that building envelopes are available on each lot. Staff is suggesting that building envelopes be defined at Preliminary Plan. The 1982 approved project is clustered, and areas having considerable environmental constraints are zoned open space. Transportation: Policy 5B requires that excessive road cuts that will create negative visual impacts will be discouraged.' The proposed road alignment crosses numerous drainages, and the applicant has verbally indicated that nine (9) different alignments were contemplated, and the current proposal represents the option having the least visual impact. No mapping, schematics, or cross section analysis has been submitted to assist the Board in assessing the impacts of the proposed access road. Water and Sewer Services: Objective 3 encourages developers to carefully analyze the site's capability to accommodate individual sewage disposal when it is being considered as a part of a development proposal. Policy 3A states that the County will require developers proposing ISDS to provide information that demonstrates to the County that the land involved can physically accommodate the individual systems.9 The original proposal, and the Geologic Report prepared in 1976, did not address the feasibility of ISDS on the site due the proposed central sewage system. Percolation test have been performed at four locations on the site, as indicated on the Drain Plan Map (Sheet 5). Soil Conservation Service mapping indicate that 8 soil groups are located on the property. The four percolation tests were located within the Gypsum-Gypsiothid Complex (#55), Urraca Moist-Mergel Complex (#109), Empedrado Loam (#35) and Almy Loam group (#6). These soil groups represent the areas most likely to have ISDS, and all had acceptable percolation rates. The 1982 approved project includes a central sewer option. Environment: Objective 1 discourages the development of land in areas of identified severe environmental constraints. Policy 1, designed to implement this objective, requires that the County shall discourage and reserve the right to disapprove (sic) development in areas with identified severe environmental constraints such as active landslides, debris slides, unstable slopes, bedrock slides, major mudflow, radioactive tailings, slopes over 25 percent and 100 year floodplain. Objective 5 requires projects ensure that development on land having moderate or minor environmental constraints consider the limitations of the land.10 Objective 6 requires that development proposals consider soil constraints as a part of the physical design, and policy 6 requires that the County discourage development in areas with severe soil constraints. Objective 9 encourages development in areas with the least environmental constraints prior to land with the greatest physical limitations." The CTL/Thompson Geologic Report included with this submittal includes identified constraints on the property (sheet 18). Identified hazards include unstable slopes, potentially unstable slopes, flash flood hazard, accelerated erosion areas and debris/mudflow hazards. The development has concentrated the majority of development in areas outside of known geologic risks. However, large portions of lots 8Garfield County Comprehensive Plan, page 8. 9Garfield County Comprehensive Plan, page 10. 10Garfield County Comprehensive Plan, page 12. "Garfield County Comprehensive Plan, page 13. • • Lots 52, 53, 54, 55, 56, 57, 58, 59, 60, 62 and 63 are in an identified flash flood hazard area. No mitigation has been proposed for this identified hazard. Performance Standards: The Comprehensive Plan includes a series of performance standards addressing specific environmental constraints, including areas having slopes greater than 25 percent. The Plan states that slopes exceeding 25 percent may be: 1. Maintained as open space; 2. Platted as a portion of an approved building envelope, with an open space easement; 3. Platted as a portion of a building lot which as adequate usable building space available other than steep slopes; 4. Platted as a portion of a subdivision and dedicated as permanent open space; 5. Developed with special design considerations and engineering.12 Slope analysis for each lot is shown on sheet 2 (Preliminary Plan Lot Layout and Dimensions). All lots have at least one (1) acre of buildable space less than 40 percent. 2. ZONING REQUIREMENTS: Section 4.08 addresses the PUD processing requirements, and the following discussion addresses specific issues with the application:13 1. Under provisions of Section 4.08.05(2)(h), the applicant is required to identify sites suitable for construction, as well as sites suitable for sewage disposal based upon the limitations described in the soils report. As described earlier, this area has significant slope and soil constraints. The applicant has agreed to provide building envelopes for each lot as a condition of approval. As noted earlier, percolation tests have been performed for the site. Results were consistent with Colorado Department of Health and Garfield County standards. 2. Under provisions of Section 4.08.05(7)(E)(i), the applicant is required to identify the proposed water source adequate to serve the PUD. The proposed water source are wells augmented by Round II sales from Ruedi Reservoir. It is not clear that such water contracts are currently available, or whether the amount identified by the applicant is adequate to support a well servicing the PUD; 3. Under provisions of Section 4.08.05(7)(E)(ii), the applicant must describe the proposed method of sewage treatment. In regards to sewage treatment, the Department of Health and the Colorado Geologic Survey have previously noted the difficulties of the system proposed in any area with soils that may not be appropriate for ISDS, and slopes that may not accept ISDS. On-site percolation tests performed by the applicant have indicated that ISDS is feasible on the site. Staff notes that soil conditions can vary significantly from one location to another. 4. Under provisions of Section 4.08.05(7)(E)(iii), the applicant must describe the general manner in which storm drainage will be handled. Exhibit H of the application includes drainage basin calculations for culvert sizing. As shown on Sheet 18, a significant portion of the northern lots on the lower bench are within an area defined as a "flash flood hazard", assumed to originate from the drainage basin during a 100 -year storm event. No mitigation for this hazard has been presented by the applicant, or a 12Garfield County Comprehensive Plan, page 2Z '3Garfield County Zoning Resolution, 1984 as amended, pages 39-41. justification for the lots proposed for the area. Staff suggests that this be a condition of approval; 5. Under provisions of Section 4.08.05(7)(F)(iv), the applicant must address legal access to the site. Garfield County Road Standards allow cul-de-sacs that do not exceed six hundred feet (600') in length. The Board of County Commissioners may approve longer cul-de-sacs for topographic reasons and it can be proved that fire protection and emergency access is provided.14 The longest cul-de-sac within the PUD extends from Native Lane to its terminus, a distance of approximately 3,695 feet in length, with no alternative access. The Fire District has approved the excessive length (See exhibit I of the application). 6. Under provisions of Section 4.08.05(7)(G), the applicant must provide evidence that the PUD has been designed with consideration of the natural environment of the site and the surrounding area and does not unreasonably destroy or displace wildlife, natural vegetation, or unique natural or historic features. The current plan, based on documentation from the Division of Wildlife cited earlier, will displace wildlife. Dog restrictions have been submitted, although less stringent than DOW are suggestions that applicant has included drainage easements to serve as wildlife corridors. Staff discussed the effectiveness of the corridors with Kevin Wright (DOW), who concluded that the corridors will have no impact on the reduction of critical habitat in the ares. Staff suggests that DOW recommendations be a condition of approval. 3. PROPOSED ZONE DISTRICTS. The application includes the following zone districts within the PUD: Residential Single Family District (R/S.F.), Residential Multi -Family Fourplex District (R/M.F.4), Residential Duplex District (R/M.F.2) and Open Space. The zone district map (Sheet 3) includes two additional zone districts: Greenbelt, Drainage and Parks and "Bikepath". The applicant has agreed to include these districts within an overall Open Space District with language included in the zone district text permitting such uses. Staff also suggested that the bikepath be relocated to County Road 109 frontage on the east end of the property. The applicant has agreed to this suggestion. The applicants are proposing to include duplexes as a conditional use within a Residential Duplex District (R/M .F.2). No maps have been submitted in regards to this proposal. This zone district would allow a duplex as a conditional use if an owner has title to two adjacent lots. Although the additional multi -family lots are consistent with Comprehensive Plan policies, staff has identified the following issues surrounding this proposal: • Garfield County has no provisions for denying a Conditional Use, only placing conditions on the application. This is significant in that it gives little or no control regarding the location of the proposed duplexes. Quite simply, ownership of two adjacent lots would be the only conceivable requirement to obtaining approval. This would have significant impact on the land use assemblage within the PUD; • The conditional use contemplated, described on page 4 of the updated zone district submittal (attached on pages- 3 3/ ), has a restriction that reads as follows: "The construction of a duplex on any two adjoining lots will not be permitted without the owner showing reasonable proof that such development will not adversely affect the adjacent lot owner's view." What constitutes a "view" is not defined, and may be too ambiguous to enforce in an equitable fashion. 1 4Garfield County Subdivision Regulations, Section 9.33(A), page 9-2. • ip • • • Since no map was submitted indicating the location of the "duplex" zoning, it is unclear what the intention of the applicant was in contemplating such a district. Since the only requirement is the ownership of adjacent lots, it appears that the only possible configuration of such a zone would encompass the entire PUD. Based on this assumption, it appears that what is contemplated is traditionally referred to as an "overlay zone". Staff suggests that if duplexes are intended within the PUD, that they be included as a Special Use within the previously defined single-family zone district. This would allow the County to deny such an application if it was deemed inappropriate by the County Commissioners on a case-by-case basis. Without such a change, a duplex could occur anywhere in the subdivision without any concern for basic subdivision design concepts originally contemplated by the developer, and the County would have no basis for denial under the Conditional Use Permit process. Staff suggests that very specific standards for denial or approval be developed in regards to duplexes within the project. The impact of the duplex zoning on the existing filings is also an issue with adjacent property owners. V. STAFF RECOMMENDATION The primary issue in front of the Board centers on the compliance and consistency of the PUD amendment with the applicable standards, as well as differences between the approved PUD zoning and the current proposal. In staff's opinion, the approved project is superior to the current proposal in the following respects: • The central sewer is consistent with Colorado Department of Health and State Geologic Survey suggestions. Staff recognizes that the financial commitment for central sewer is significant, although fmancial feasibility is not a criteria addressed in the Garfield County Subdivision Regulations or Zoning Resolution. • The approved project is based on a cluster concept, focussing development activities in areas with the least environmental constraints, retaining open space adjacent to existing development in Filings #1, #2 and #3, and limiting impact to critical wildlife habitat; • The scope of the multiple -housing proposed in the original PUD is more consistent with the goals and objectives of the Comprehensive Plan. Staff concedes that the proposed project is feasible from an engineering perspective, although the spirit and intent of PUD regulations does not rest completely on engineering criteria. The Planning Commission recommended approval of the PUD amendment with a vote of 5-2, with John Foulkrod and Calvin Lee dissenting. Conditions placed on the project by the Planning Commission are as follows: General 1. All representations, either within the application or at stated at the public hearings before the Planning Commission and the Board of County Commissioners shall be considered conditions of approval unless stated otherwise by the Planning Commission and the Board of County Commissioners. Geology 2. The Preliminary Plan shall have a building envelope designated for every lot within the PUD. All building envelopes will avoid active and older landslides, manmade fill, and unsuitable slopes. No lot will be created that does not contain an acceptable building envelope. No lot shall be created that is smaller than the minimum lot size allowed in that particular zone district. 4,1 • • 3. An engineered foundation shall be required for all structures within the PUD and submitted with building permit applications. Furthermore, all final plats shall have the following plat notes: Zoo AN14/ A. Prior the issuance of a building permit, he owner of each lot shall prepare and submit a soils and foundation report, and ISDS design, and a grading and drainage plan prepared and certified by a professional engineer. All improvements shall be constructed in accordance with such measures which shall be a condition of the building permit. Water Supply 4. At the time of Preliminary Plan, the applicant shall demonstrate evidence of adequate water quantity from the proposed well field for the project. Zone Districts The bikepath and drainage districts shall be included within the Open Space Zone__ District with appropriate language and to the Zone District text. N- The duplex concept should be integrated as a Special Use within the single-family residential district. Wildfire 7. All building envelopes identified at preliminary plan shall be not be located in or at the head of drainages. Flashflood 8. Prior to Preliminary Plan, the applicant shall determine the 100 year floodplain, consistent with the recommendations of CTL/Thompson Reconnaissance Report. Existing Infrastructure 9.

Long Division Director Vicki Cowart State Geologist and Director GA -94-0001 At your request and in accordance with S.B. 35 (1972), we have reviewed the materials submitted for and made a field inspection on July 13, 1993, of the site of the proposed residential subdivision referenced above. The following comments summarize our findings. (1) Generally, the assessment of potential geology -related problems in this subdivision presented in the analysis by CTL Thompson is thorough and adequate. Although there are some parts of the project area that have moderate to severe geologic hazards, these will be adequately avoided of the subdivision is developed as shown on the proposed plat. The lot sites are sufficiently large that a safe building site can be selected on each one although such "safe build" areas on some of the lots are relatively small, especially on lots 1 and 2 and lots 35 to 43, inclusive. (2) We strongly concur with the recommendation by CTL Thompson that each lot and building site be investigated by a qualified engineering geologist and/or soils and foundation engineer who should collaborate with the architect for proposed structure(s). Careful siting of structures, proper control of drainage, and properly designed building foundations (including their concrete specifications) will be critical to minimizing construction and maintenance problems for future homeowners in the area. (3) It is likely that maintenence costs for roads and other infrastructure in the subdivision will apt to be higher than that typical of subdivisions in more gently sloping and less hazardous terrain. The County should evaluate these costs for any facilities Mr. Dave Michaelson July 21, 1993 Page 2 that may be dedicated to it for maintenance, e.g. roads. (4) The feasibility of use of individual sewage -disposal systems on lots of this size, in terrain which is relatively steep in many places, and where bedrock is at or near the surface is highly questionable. The admission in the submitted documentation (p. 2,3) that a "replacement" leach field site should be planned for on each lot is an indication that the proponent is considering the possibility that individual septic systems will eventually fail. It is our opinion that the subdivision should be placed on a central sewer system served by its own sewage- treatment plant. Eventually, when it is economically feasible to join a larger sewer district (possibly the proposed Aspen Glen facility), this subdivision should do so. Minimizing duplicity of sewage -treatment facilities is a policy of the Colorado Department of Health, Water Quality Control Division. In summary, this project is feasible, but only with careful planning down to the siting of homes on lots. Some of the project area that must be used for locations of roads, utility corridors, and other infrastructure is geologically hazardous and will necessitate higher than ordinary maintenance and repair costs. The sizes of lots and geologic conditions make the feasibility of use of individual sewage -treatment systems questionable. Sincerely, mes M.

Proposed lot 91 is the only parcel adjacent to public land. 1. The landowners should be aware of the location of property boundaries to ensure no encroachment occurs on public land. Should fence construction be considered along the BLM boundary, the fence standards should allow for easy passage by big game, i.e. less than 42" in height with a 10" kick space between the top 2 wires. 2. The parcel of BLM administered land adjacent to lot 91 has been designated as a disposal tract in the BLM's Resource Management Plan. Current or future owners of this lot 91 should not expect the BLM tract to remain in federal ownership. 3. Rocky Mountain Natural Gas Company is proposing to construct a pipeline near or within the 100 foot Public Service Company utility easement depicted on the sketch plan. Any utilities proposed for the subdivision that cross public land would have to obtain a right-of-way from this office. 4. The adjacent public land is not allotted for livestock grazing. 5. Adjacent public land is open to hunting. The proponent should be aware that such recreation uses are allowed on BLM-administered land. 6. After review of our mineral survey notes, there are no federal minerals located within the subject private lands. 7. Development of this nature, especially at the density proposed, would likely render the critical winter mule deer habitat (which is in relatively poor condition) unsuitable for deer use. The development could increase deer use on adjoining public and private lands particularly during the winter months. • • Garfield Planning - Page 2 8. The soils within the proposed subdivision are poorly suited for housing development due to shallow depth to bedrock, steep slopes, and very high hazard of water erosion.

We stand by our recommendations in that letter regarding ways to minimize those impacts. In addition to those recommendations, we recommend the following: 1. If dogs are allowed, restrict to 1 dog/home. All kennels be constructed before C.O. is issued. Based upon our experience, electric fencing does not always work; a physical kennel is preferred. 2 Any rail fencing be 48", 3 -rail or less with at least 18" between 2 of the rails. The following issues did not appear to be addressed in the last submission: 1. Density was reduced; however building envelopes were not designated. We would recommend these be placed in the nearest 1/3 of each lot closest to roadways and set back from any hillside. If possible clump homesites. 2 All utilities be buried. 3 No horse/livestock grazing. If allowed, homeowner fence haystacks with 8' fencing to prevent damage to haystacks which is an attractant to big game. 4. Maintain native vegetation outside building envelope. 5.

We observed about twenty live deer browsing, three carcasses of deer lost during this winter, heavy utilization of sagebrush and rabbitbrush plants by big game, heavy use of trails into and out of the area and concentrations of pellet groups along ridge tops. Division of Wildlife mapping places Westbank Ranch Filing 114 in elk winter range and in critical deer hahitat (meaning that loss of this critical winter range would adversely affect deer). Development of Westbank Ranch Filing 114 will stress big game populations because of increased domestic dogs running at large, loss of native vegetation, increased erosion, increased vehicular traffic, increased human/wildlife interaction and increased obstacles to negotiate such as fencing. We would like to recommend the following methods of minimizing impacts to current wildlife occupants: 1. Reduce the density of 98 single family homesites by the use of fourplex lots, duplex lots, clumping homesites, and/or eliminating some lots or combining lots into larger lots. 2. Require underground utilities to protect raptores (birds of prey) from electrocution. (A pair of golden eagles nest very close to this development.) 3. Require fencing restrictions. No wire fences. Wood and wood rail fences a maximum height of 48 inches with a maximum of three rails (allows for fawns to pass between rails) except for solid privacy fences which should be a minimum of 72 inches. 4. No dogs allowed. DEPARTMENT OF NATURAL REc' WILDLIFE COMMISSION, George VanDenl3erg, Chaim- o/• itdon W. Cooper, Member • Rebecca L. Frank, Member • D, , Hamlet J. Barry, Executive Director O.

No livestock allowed on any lot. (Livestock, especially horses on small dryland lots denude native vegetation, increase erosion and increase wildlife damage to neighboring property owners from wildlifes attraction to hay fed to livestock.) 6. Restrict building of ar►y structure to the third of each lot nearest the roadway. (This would help reduce loss of native vegetation.) 7. Require the developer to Include the following information to buyers of each lot: A. These homesites are located in critical deer and elk winter range. Taller browse plants such as sagebrush, oakbrush, mountain mahogany, serviceberry and bitterbrush usually protrude through the winter snows and are important to the survival of big game. Homeowners are encouraged to maintain native vegetation. B. Deer and elk can damage or destroy ornamental plantings. For suggestions to prevent wildlife damage and types of ornamentals less susceptible to damage, contact the Colorado Division of Wildlife. C. Death is natures way of keeping wildlife in balance with the amount of remaining habitat. Wildlife mortality rates are increased by human and pet interaction with wildlife.

GA FIELD COUNTY RE: Westbank Ranch Filing #4 PUD Amendment and Preliminary Plan Section 35, T6S and Section 2, T7S, R89W, 6th P.M. Water Division 5, Water District 38 Dear Mr. Michaelson: oy Romer Governor Ken Salazar Executive Director }1941 D. Simpson State Engineer Thank you for the referral concerning the amendment to the Westbank Ranch Filing #4. The project is located approximately five miles south of Glenwood Springs along Highway 82. The change includes downsizing the project from 98 dwelling units to 67 dwelling units. In addition, instead of expanding the existing water supply, the modified plan anticipates a separate water distribution system from eight proposed wells. Out -of -priority depletions are proposed to be augmented with releases from Ruedi Reservoir. All lots will have non -evaporative septic systems. We can recommend approval for the preliminary plan only. Prior to approving a final plan for this project, the following issues must be addressed: • A court approved water supply plan must be decreed. The applicant has filed a plan for augmentation, Case 93CW104, which has not been adjudicated, yet. If the applicant wishes to be covered under the West Divide Water Conservancy District substitute water supply plan while proceeding with the Court process, the applicant must conform with the parameters of the District's plan. • The Protective Covenants should include specific language concerning the management and responsibility of the eight wells in the central water supply system; the amount of irrigated acreage each lot may have; the amount of livestock allowed per lot; and that all lots must use a non -evaporative septic system. All these conditions will be stipulated in the final decree. Because the augmentation plan is still pending, additional conditions may be imposed when the plan is decreed. Our April 13, 1993 letter to the County for the modification to Westbank Ranch Filing #4 was in response to a change from a multi -family to single family concept. The proposed water supply was from four decreed wells. Our April letter does not apply to this submittal. Should you have further questions or comments regarding our concerns for the water supply for this project, please contact me at the above address.

The modifications are being proposed because it is felt that the density of lot of the original plan in keeping with development that has occurred in the general area. Additionally, the difficulty in permitting and constructing sewage treatment facilities which would discharge to the Roaring Fork River has caused the construction of a central sewage collection system to be impractical. The modified concept provides lots with sufficient space for a Targe single family home and onsite sewage treatment facilities to serve it. The Tots are configured to take advantage of the natural views of the area. The development layout includes common open space which will be dedicated to the homeowners association. The proposed Westbank Ranch Filing #4 Resubdivision is illustrated on the following drawings: SHEET 1 OF 18 --PRELIMINARY PLAN TOPOGRAPHIC MAP SHEET 2 OF 18 --PRELIMINARY PLAN LOT LAYOUT AND DIMENSIONS SHEET 3 OF 18 --ZONE DISTRICT MAP SHEET 4 OF 18 --UTILITY PLAN MAP SHEET 5 OF 18 --DRAINAGE PLAN MAP SHEET 6 OF 18 --OVERALL ROAD PLAN MAP SHEETS 7 THROUGH 15 OF 18 --ROAD PLAN AND PROFILE SHEETS SHEET 16 OF 18 --SOILS GROUP MAP SHEET 17 OF 18 --RECONNAISSANCE GEOLOGIC MAP SHEET 18 OF 18 --RECONNAISSANCE GEOLOGIC HAZARD MAP PAGE 1 a3 • • THE PROPOSED MODIFICATIONS TO THE EXISTING PUD PLAN ARE AS FOLLOWS: 1. Dwelling Type and Number The current plan contains 10 fourplex lots, 10 duplex Tots and 38 single family Tots for a total of 58 lots with 98 dwelling units. The modified plan contains 63 single family Tots and one multi -family, fourplex lot for a total of 67 dwelling units. 2. Lot Size The current plan contains lots ranging from 0.44 acres to 1.94 acres, with 36 of the 58 Tots being less than one acre. The modified plan contains lots ranging from a minimum of 1.0 acre to 14.26 acres, with the majority of lots in the 2.0 to 3.0 acre range. 3. Site Plan The current plan calls for 81 dwelling units on the upper bench and 17 on the lower bench. The modified plan (see map) calls for 51 single family dwelling unit Tots on the upper bench and 13 lots on the lower bench. Of these 13 lots, 12 are for single family dwelling units and one (number 64) is a multi -family, fourplex lot. In addition, it is proposed that duplex units may be permitted on any two adjoining lots, subject to a conditional use permit being granted by the County, and the conditions listed here under "B. Uses, conditional". 4. Domestic and Irrigation water Supply The current plan anticipates expansion of the existing water system which serves Westbank filings I through III. The modified plan anticipates a system separate from the existing Westbank system, with water to be supplied from new well(s) to be drilled and augmented with Ruedi Reservoir water for which a contact has been obtained. A total of 40 acre feet of water is to be purchased from Ruedi Reservoir for the needs of the development. As a part of the water system development, sufficient irrigation water will be provided to allow for each residence to irrigate up to 2,500 square feet. Fire protection storage and hydrants will be incorporated in the domestic water system. A letter report and documents related to the purchase of water from Ruedi Reservoir are attached as EXHIBIT E. 5. Sewage Disposal The current plan anticipates the construction of a central sewage collection system and treatment plant. PAGE 2 47V - • • The modified plan anticipates the use of individual, onsite sewage treatment and disposal systems. Each lot will be designed to accommodate the space necessary for a leach field disposal system as well as space for a second, "replacement" field. Percolation rate tests were conducted at four separate sites on the property which were representative of the soil condition of the development. The locations of the tests are illustrated on the RECONNAISSANCE GEOLOGIC MAP. The results of these tests are as follows: Test # 1 Test # 2 Test # 3 Test # 4 16.90 minutes/inch 10.37 minutes/inch 8.34 minutes/inch 14.46 minutes/inch All of these test results are acceptable for the construction of leach field systems for onsite sewage treatment and disposal systems. Individual percolation tests must be accomplished for each specific leach field site prior to construction. 6. P.U.D. Zoning Regulations The current P.U.D. zoning regulations are attached in EXHIBIT A. The modified plan anticipates changing the regulations to read as follows: Section I. A. To carry out the purposes and provisions of the Garfield County Zoning Resolution, Garfield County, Colorado and, particularly, Section 1 .04 of that title, as amended, the Westbank Ranch Planned Unit Development Zoning District is further divided into the following Zone District classifications: R/S.F. - Residential Single Family District R/M.F.2 - Residential Duplex District R/M.F.4 - Residential Multi -Family, fourplex District O.S. - Open Space B.

Wildlife The Division of Wildlife mapping places this development in elk winter range and critical deer habitat. It is understood that some impact on the big game herds will result from this development. The following conditions are proposed as additions to the protective covenants of the development to mitigate some of the impact. PAGE 7 -P9- • • A. Dogs shall be kept under the control of the Owner at all times and shall not be permitted to run free or to cause a nuisance in the subdivision. No dogs shall be allowed beyond the boundaries of the lot owned by the persons where the dog is housed unless accompanied by a person in full control of such dog. B. Dogs shall not be allowed to bark continuously, which shall be defined as barking for a continuous 15 minute period. C. Dogs shall be leashed, chained, fenced, "electric fenced", kenneled, or under the control of the Owner, which shall mean that the dog does not leave the boundaries of the lot or house unless on a leash and under the control of a person at all times. Metal fencing will be allowed for the purposes of kenneling a dog. Location of kennels shall be subject to review of the Architectural Control Committee. D. All lot owners shall keep all pets reasonably clean and all lots shall be free of refuse, insects, animal waste and insects which breed thereon, at all times. E. The Homeowners association shall assess and enforce penalties against Owners violating the restrictions applying to dogs as follows: One hundred Dollars ($100.00) for the first violation committed by an Owner's dog; Two Hundred Dollars ($200.00) for the second violation; Three Hundred Dollars ($300.00) for the third violation and for each succeeding violation the fine increases in One Hundred Dollar ($100.00) increments. Should any dog chase or molest deer, elk, other pet animals or persons, or destroy or disturb property of another, the Association shall be authorized to prohibit the property owner or resident from continuing to maintaining the offending animal on his property and may dispose of that animal, in necessary, to protect wildlife or other Owner's pet animals, persons or property. The offending dog owner shall be provided written notice of such action at least two (2) days before disposal occurs. Within such two-day period, the offending dog shall be kenneled at a licensed kennel. All charges associated with action taken by the Association may be assessed against either the lot Owner and/or the dog owner, or both at the Association's sole option. F. Notwithstanding the foregoing, no animal may be kept within a lot or residence which, in the good -faith judgement of the Association Board of Directors, results in any annoyance or are obnoxious to residents in the vicinity of to lot Owners within the subdivision. Except as expressly limited herein, domestic animals may be further restricted pursuant to any rules and regulations which may be promulgated by the Association Board of Directors. G. Metal fencing shall not be allowed except for kennels as noted above. No kennel shall cover an area greater than two hundred and fifty (250) square feet. PAGE 8 ! • Wood and wood rail fence shall have a maximum height of 48 inches with a maximum three rails to allow for a fawn to pass between rails. Solid privacy fences, where permitted by the Architectural Control Committee, shall be a minimum of 72 inches high. 19. Wildfire Hazard The area of this development, which is in excess of 30% slope and in the densely vegetated drainages, has been identified as medium to high hazard for wildfire, in a letter from Mr. Kelly Rogers of the Colorado State Forest Service. The site was also visited by representatives of the Carbondale & Rural Fire Protection District. As a result of this visit, a letter was written by Mr. Ron Leach, Chief of that district and a Memorandum was written by Mr. James Mason, Director of Glenwood Emergency Services. Recommendations were made regarding the development in all three of these communications. As a result of these recommendations, the following conditions are proposed as additions to the protective covenants of the development to mitigate this potential hazard: A. Structures shall not be constructed in or at the head of topographic drainage features. B. All vegetation except low ground cover such as mowed grass shall be removed for an area 10 feet on all sides of all structures. C. Brush and trees within 30 feet of all structures shall be thinned, if necessary, so that the remaining clumps are no more than 10 feet wide. D. Structure roof coverings shall be of non-combustible materials. Additionally, the design criteria proposed by Mr. Leach and Mr. Mason is incorporated in the road and utility design.
