The following is included with this transmittal: 1. Revised Reserve at Elk Meadows, PUD Master Plan, Revision Date — 5/14/07. The revised Master Plan shows ten duplex lot intended specifically for compliance with the affordable housing requirement. The plan also reflects the modified rear lot setbacks in the lots above Four Mile Creek and the relocation of Lots 1-4 (as shown on the original master plan) in the East Meadow neighborhood. 2. Reserve at Elk Meadow, Profile Street A 3. Letter from Sopris Engineering Letter dated 5/15/07 4. Revised Section 4.08.05 (2) (1) Phasing. This revision adds an additional construction phase to accommodate the development of core infrastructure and recreation facilities, the realignment of Four Mile Road and the creation of the affordable housing lots as the initial phase of the development. 5. Revised Construction Phasing Plan, dated 5/15/07 6. Revised Section 4.08.05 (7) (b). This section provides specific dates for the completion of each phase of construction. 7. Revised Zone Text. The revised text contains a new zone district titled "Attached Residential" which is intended for the affordable housing units and a section at the end describing criteria to be used in the evaluation of any future requested changes to platted building envelopes. We continue to believe that building envelopes on all lots are the best avenue to protect environmental and visual resources at the site. In response to Condition of Approval # 8, the Applicant proposes that all roads be dedicated to the public but maintained by the home owner's association. Please contact myself or Larry Green, if you have any questions or require any additional information. Ron Liston RECEIVED MAY 1 6 2007 GARFIELO COUNTY BUILDING & PLANNING May 15, 2007 Ronald B. Liston Land Design Partnership 918 Cooper Avenue Glenwood Springs, CO 81601 Re: Reserve at Elk Meadows Development, Reply to Staff Recommendations of April 11, 2007 SE Job #: 25019.01 GARI"IFLO Cpr JNrY BUf1.DWG a PLANNING Dear Ron: KAY 1 6 2007 This letter addresses the engineering concerns generated by the Planning Commission in their April 11, 2007 meeting to review the Reserve at Elk Meadows PUD Sketch Plan Application. Specifically addressed in this letter are the issues that the Planning Commission wanted resolved prior to the public hearing before the Board of County Commissioners. The Staff comments are shown below in italic text while our responses to those items are shown in bold text. The remaining engineering concerns will be addresses prior to submitting the Preliminary Plan. Staff Recommendation VII. 5. on Page 49 states: "The Applicant shall provide the 10% affordable housing unit requirement on site within the development." • Affordable housing has been added to the development as duplexes on lots 54-63 of the South Meadow. This new configuration is shown on the revised "P.U.D. Master Plan" Staff Recommendation Vil. 9. on Page 49 states: "Prior to the public hearing before the Board of County Commissioners, the Applicant shall provide a letter from the Glenwood Springs Fire District that specifically approves of the internal road network, design and grade." • Sopris Engineering provided Ron Biggers at the Glenwood Springs Fire District with the information needed to review the internal roads and we have met with him regarding this issue. He has said he will provide a letter addressing the road design but we have not received it yet. Sopris Engineering will provide this letter to the County prior to the BOCC meeting. Staff' Recommendation VII. 11. on Page 49 states: "Prior to the public hearing before the Board of County Commissioners, the Applicant shall provide an analysis that the road grade of "Street A" can exceed 8% using the standards in Section 9:37 of the Subdivision Regulations of 1984, as amended. " • Street A is classified as a minor collector per the Garfield County Standards and therefore should have a maximum grade of 8%. Sopris Engineering has provided graphic illustration showing the road profile for Street A and where it exceeds an 8% grade. We are proposing a maximum 10% grade for the following reasons (based on criteria in section 9:37 of the Subdivision Regulations): 1. The current design has approximately 3200 feet of road at a grade of 10%. The resulting elevation change for that length of road at 10% is 320 feet. To achieve the same elevation change with an 8% road, the length of road would have to be increased from 3200 feet to 4000 feet (an 800 foot increase). An increase of 800 feet of road with an average disturbance area 40 feet wide would mean 32,000 Sq. Ft. of increased disturbance to the development. Increasing the length of Street A by 800 would also result in two more switchbacks to be able to avoid the property boundary and tie into the existing road design for the Upper Meadow. The added switchbacks and 32,000 Sq. Ft. of disturbance would be a significant increase to the disturbed land already proposed. From an emergency access standpoint, 10% is an 502 Main Street • Suite A3 0 Carbondale, CO 81623 0 (970) 704-0311 0 Fax (970) 704-0313 SOPRIS ENGINEERItIC • LLC civil consultants SE. JOB 25019.01 May 15, 2007 Page 2 acceptable grade, to redesign the road at 8% with two additional switchbacks is a much less desirable option. 2. Currently, using 10% maximum grade, the proposed design has centerline cuts of 8-10 feet and retaining walls approximately 10-20 feet high in spots. To follow the same alignment with an 8% grade would result in larger cuts and retaining walls than are currently proposed. 3. The excessive grades have been minimized in length to provide a safe design at intersections while maintaining access to all Lots. 4. The sections of Street A that are currently designed at 10% grade have significant southern exposure that will minimize snow and ice buildup by maximizing solar exposure. 5. While the proposed grades of 10% on Street A exceed 150 feet in length, they are not on a dead end and therefore do not require turnarounds for fire equipment requirements. 6. The 10% maximum grade proposed will still permit the transport of fire fighting water by the Glenwood Springs Fire District. Staff Recommendation V11. 16. on Page 50 states: "Prior to the public hearing before the Board of County Commissioners, the Applicant shall address the comments made by Mountain Cross Engineering regarding pressure zones and gallon usage." Exhibit H clarifies those items as follows: 1) The water demands that were estimated for the augmentation plan (350 gpd) differ from those estimated for the water system (450 gpd). These should be congruent or explain the rational behind the discrepancy. • The water augmentation plan (by Zancanella & Associates) included calculations for the irrigation system and potable system and assumed 1.5 EQR's for each residence at 350 gpd per EQR which is for legal water at 525 gpd. The water system calculations (by Sopris Engineering) were designed included an estimated peak flow of 450 gpd for tank and water line sizing. The two values are not congruent due to the irrigation calculations and one is for legal water while the other is for system performance design. 2) The project is proposed to have two pressure zones, with pressures ranging from 170 psi to 40 psi. Pressures of 170 psi are very high. Generally speaking 100 psi is a more realistic maximum for residential plumbing fixtures. More pressure zones or individual residential PRV's should be considered. • The water system has been designed with a pressure at the residences of approximately 150 psi which in our experience is standard in industry. If it is determined that the max allowable pressure should be 100 psi we can modify our design to include additional PRV's without affecting the system design (tank or mainline location). If you have any questions or need any additional information please give us a call. Sincerely, SOP ,IS G1NEE65 Chris J. uJ, E.I.T. De ig ngi e -r Y: cy Nichol, P.E.

On behalf of the Applicant, this letter responds to the Colorado Division of Wildlife's (CDOW) March 16, 2007 referral letter. The Project's draft Wildlife Mitigation and Enhancement Plan and the Applicant's current development proposal already incorporates most of the CDOW's recommendations. In general, I believe that implementation of the CDOW's recommendations that are not currently part of the project's draft Wildlife Mitigation and Enhancement Plan and the Applicant's current development proposal would only incrementally improve the development plan for wildlife. However, planning must consider multiple resources and community concerns. As recognized by the CDOW in their referral letter and County in their staff report, the Applicant as gone a long way to preserve large blocks of important wildlife habitat, cluster development in non-native habitats, preserve multiple movements corridors facilitating continued wildlife use of the property, and minimize overall development effects. From a wildlife perspective, this Applicant has gone beyond what others would propose to preserve wildlife values, while balancing those values with other community concerns. Below, I address specific CDOW's recommendations of concern to the Applicant. The CDOW's proposed relocation of lots 18-23 (Staff Report, Condition 4) would better cluster development along Road A, but may not reduce impacts to native habitat (as illustrated on the Illustrative Master Plan) if lots are strung out between Lots 17 and 24. The purpose of this part of the plan is to preserve the upper part of the meadow, which is quite visible from Highway 82. This is a wildlife vs. visual sensitivity issue that the County will have to balance. The CDOW has proposed a 100 foot open space corridor along the common boundary with the Four Mile Ranch Subdivision, which, together with that corridor, would provide a 200 foot corridor between respective building envelopes/ individual property line. Currently, the Applicant is proposing a corridor approximately 85 feet wide from the rear of the building envelopes to the property line, except for behind Lots 35 and 36 where it narrows to 50 feet (R. Liston, pers. comm., Apr. 6, 2007). However, because of the configuration of those building envelopes there is going to be a greater width of unobstructed corridor than the 50 foot dimension might suggest (R. Liston, pers. comm., Apr. 6, 2007). Fencing will not be allowed outside of the building envelope so the current plan nearly achieves the CDOW's request. The 150 foot wide bottleneck would theoretically be less functional for wildlife movements than a continuous corridor 185-200 feet wide, but it is unlikely that even the 200 foot corridor would encourage elk movements. Furthermore, while multiple corridors are theoretically more functional at conducting wildlife movements, my recommendation to the Applicant to facilitate continued deer and elk access to the strip of winter range above the Roaring Fork River was to provide a primary, highly functional corridor along the south side of the property by keeping development out of the areas south of Four Mile Creek and out of the Four Mile Creek drainage. That recommendation was incorporated into the current development plan. Implementing the CDOW's recommendation would require considerable reworking of the plan and disrupting other open space and view sheds of cultural importance to the public traveling along Four Mile Road (R. Liston, pers. comm., Apr. 6, 2007). On East Meadow Lots 1-22, the CDOW requested a minimum 50 foot development setback from the edge of the terrace along the north side of Four Mile Creek to provide a wider buffer between winter range use and wildlife movements through native habitats below. Broader setbacks could facilitate greater wildlife (primarily elk) use of native habitats at the top of slopes adjacent to homes, although virtually all other wildlife now using the property will habituate to human presence and enter these adjacent backyards, increased setback or not. Nevertheless, for wildlife and other reasons, the Applicant has removed Lots 1-4 and is willing to pull development envelopes further back from the terrace's edge to the extent practicable within remaining lots. The CDOW has proposed eliminating the park and trail from the Four Mile Creek corridor. While the CDOW recognizes that the proposed elimination of catde grazing from that riparian corridor and subsequent riparian enhancement, they contend that a 6 -foot -wide gravel path and diurnal human use would negate any wildlife benefits. While recreational trail use of riparian corridors has been shown to adversely affect some (primarily non -game) wildlife values, I believe there would still be a net gain to wildlife in this context and the Four Mile Creek corridor and undeveloped lands to the south would remain functional for wildlife movements. The proposed park and nature trail is one of the highlights of the property for residents. Apparently, the Planning Director commented on how much he liked these proposed recreational amenities (R. Liston, pers. comm , Apr. 6, 2007). People are going to be down in the creek corridor whether a trail is built or not. In my experience, it is better to sensitively site and install such a trail (e.g., keeping the trail on one side of the creek, maximizing the size of undisturbed habitat blocks, etc.), directing human use, rather than having more widespread use and multiple volunteer trails develop with greater adverse effect. This is a wildlife vs. passive recreation issue. With the exception of the CDOW's ambiguous statement (Page 2, Para. 5, #2) about eliminating all internal fencing, the remaining CDOW recommendations and suggestions are already part of the draft Wildlife Mitigation and Enhancement Plan or can be added. The Applicant proposes to restrict all internal fencing to be within designated building envelopes and will through covenant restrictions and guidelines minimize the use of fencing except for privacy fencing near the homes and for dog kennels. Such fencing associated with the development clusters should not adversely affect wildlife movements or deer and elk use of residential landscaping. In summary, while implementing those CDOW recommendations that are not already part of the project's draft Wildlife Mitigation and Enhancement Plan and the Applicant's current development 2 proposal may make the development slightly more compatible with wildlife, it would do so at the cost of scenic/ visual, recreation, and other considerations that are important to the broader community. Please call me if you have any questions. Sincerely, Richard W. Thompson Certified Wildlife Biologist Western Ecosystems, Inc. RWT/s Cc: R. Liston 3 gwc oP/y SPS fA The Upper Meadow is a southeast oriented open field located north of the Martino and Bersheny homesteads. All of the Upper Meadow lots back' out on to dedicated open space and typically 5vi;v ;•./ range from 17,000 square feet to well over 30,000 square feet in size. The central open space areas are currently pasture land and will be refurbished as native meadows where not included in residential lots. Rear lot areas extending onto steep slopes and into native vegetation are overlain with open space easements to protect native terrain and vegetation from disturbance. The ridgelines to east and north of the Upper Meadow, which are highly visible from Glenwood Spring, the upper Four Mile Creek valley and Hwy 8 2, are protected from homesite development. Also, the highly visible large meadow located north over the ridge from the Upper Meadow (Far North Meadow) is preserved as open space. Lots in all three neighborhoods are proposed to be platted with specific building envelopes which, in the case of the rear setback, is typically much more restrictive than called for by the PUD zone regulations. Protective covenants will include limitations and guidelines to control landscaping and site improvements within and outside of the building envelope. On lot parking requirements range from four to six parking spaces depending on the size of the residence constructed. Interior Roads: The entry drives both to the east and to the west are proposed as boulevard style channelization to control and slow traffic, assure access by emergency vehicles and to provide opportunity for landscape treatments. To the east the boulevard street cross section is continued to the first intersecting street to assure emergency ingress and egress to the East Meadow lots. The typical road section throughout the community is two eleven foot asphalt paved lanes with a one foot wide flush concrete curb to preserve the asphalt edge. A ten foot wide asphalt emergency access and pedestrian trail are provided from the Upper Meadow to the lower main access road along the alignment of the existing ranch road. Additional controlled access gravel surfaced drives are located in the Upper Meadow and South Meadow to assure access by emergency vehicles. The emergency access drives also serve as important links in the pedestrian trail system. Supplemental parking is provided throughout the community with bays of three to five parking spaces positioned perpendicular to the roadway. Covenants will restrict the length of time autos may be parked in these areas such that they truly serve as guest parking. This application requests the ability to dedicate the interior roads to the Elk Meadows HOA which will also maintain all roadways. Trails: The Four Mile Valley Community Trail, an eight foot wide asphalt path currently ending at the south boundary of the Four Mile Ranch Subdivision, will be continued up valley through the Elk Meadows community, bridging across Four Mile Creek and ending at the south boundary of the Elk Meadows PUD. The trail will remain east of Four Mile Road and be located in a twenty foot easement dedicated to the public. The trail connecting the Bershenyi Barnyard area with the public parking area at the north end of the Upper Meadows neighborhood will be a six foot asphalt trail typically located at the backside of the one foot flush curb at the edge of the interior roads. In some areas this trail will be removed from the road edge and in other areas the trail will coincide with an emergency access drive. A six foot gravel trail is proposed along the north side of Four Mile Creek, downstream from the Four Mile Valley Community Trail and continuing up through the East Meadow connecting again with the pubic trail near the Four Mile Ranch and Elk Meadows common north boundary. ---1°Y)24t Elk Meadows Barnyard: The area east of Four Mile Road around the Bershenyi barns (the Barnyard) is intended to be the social and visual focal point of community. This area is proposed to include: - the relocated Bershenyi log barn which will be stabilized and preserved; - the Bershenyi frame barn which is proposed to be cleaned up and preserved; - vehicular parking for activities at the Barnyard and Four Mile Creek Park; - children's play equipment and typical park furnishings; - attractive landscaping to enhance the appeal and character of the Elk Meadows community; - some additional small Bershenyi Ranch structures may also be preserved in this area; - the Four Mile Valley Public Trail will pass through this area. Heritage Ranch: The applicant has offered to cooperate in the creation of a "Heritage Ranch" located at the Barnyard site, if there is public support for the creation of a non-profit corporation for that purpose. The earlier described twenty acre hayfield could also be included as an element of the Heritage Ranch. The proposed Community Facilities Open Space Zone District regulations have been written to accommodate activities and uses that are anticipated to be associated with a .:heritage ranch facility. Four Mile Creek Park The Four Mile Valley Community Trail will provide access from the Bershenyi Barnyard down to Four Mile Creek where a modest park facility will be created including the following: - small turf grass areas that serve as collection nodes along the creek; - one small picnic shelter at one of the grassy nodes; - gravel trail described earlier connecting the grassy nodes; - park furnishings such as benches and picnic tables. Efforts will also be made assist the riparian vegetation in recover from years of cattle grazing. East Meadow Mountain Meadow Park: lid The interior open space area surrounded by East Meadow lots is proposed to be developed in a character similar to a high country park surrounded by aspen /spruce. The proposal is to create a couple irregular shaped irrigated areas maintained as turf grass to allow for casual open field recreation and to surround these lawn areas with native grass areas planted with scattered groupings of deciduous and evergreen tre s and masses of large shrubs. Gentle earth berms may be included particularly if large boulders from the on-site construction activities can be incorporated into the berms to create an exciting, creative and unstructured environment for child 6 play. All landscaping will be supported by irrigation. The earlier described gravel trail will flow through the fringes of this Mountain Meadow Park connecting it and the East Meadow lots to the Four Mile Creek Park and the Four Mile Valley Community Trail. South Meadow Mountain Meadow Park: The large open space in the interior of the South Meadow will be developed similarly to the center park in the East Meadow except that there will be a large pond And much less lawn area. The pond will serve as the pumping basin for a proposed raw water irrigation system that will deliver pressurized irrigation water to all lots. The nature of the raw water supply should allow for minimal fluctuation of the water level in the pond during most of the irrigation season. There is also a small interior open space area in the northerly section of the South Meadow which will be developed as a small scale park. North Ridge Observation Shelter: The ridge line at the north edge of the Upper Meadow commands spectacular views of the Roaring Fork Valley, the Four Mile Valley and the Flat Tops to the North. A small observation platform and low profile shelter are proposed on the ridgeline up slope from the public parking lot to take advantage of these views and to create a destination point on the pedestrian trail system. The small size and architectural lines of the shelter will minimize its visual presence on the ridge line, if it is seen at all above the oak brush. Affordable Housing: The Elk Meadows community is nearly two miles from the closest commercial and social services with no public transportation located any where hear the property. Therefore, the PUD site is not a desirable location for affordable community housing units. The applicant proposes to comply with Garfield County affordable housing regulations at a location within Glenwood Springs or other area community. Details of how the applicant will satisfy the affordable housing regulations will be presented at the time of preliminary plan. UTILITY SERVICES Water Rights Domestic water rights protection is proposed to be provided by contracts on the Roaring Fork River and senior rights historically attached to these properties. The water rights program will require the completion of a court approved augmentation plan prior to approval of the preliminary plan. Limited area of landscape irrigation is included in the calculations for the domestic water supply but additional irrigation will be provided from a proposed raw water delivery system. Water Supply The domestic water physical supply will be provided by wells located along Four Mile Creek just east of Four Mile Road with a building for chlorination facilities located near the wells. In the early phases of the community development, water will be pumped to a storage tank located on the east edge of the Upper Meadow to provide gravity feed back to all lots and to fire hydrants located in the East and South Meadow neighborhoods. Development of the Upper Meadow will include an additional water storage tank located up slope from and northwest of 7 Paved pedestrian trails connect the public pedestrian trail located east of Four Mile Road with access to the proposed "mountain park". (3) The PUD shall provide parking areas adequate in terms of location, area, circulation, safety, convenience, separation and screening. On lot parking requirements are discussed in Section 4.07.02 above. Guest parking is proposed at additional locations throughout the residential neighborhoods and parking is provided for users of the proposed "mountain park" at the north end of the Upper Meadow. This location offers convenient access to the old ranch road which provides pedestrian access to the "mountain park". Additional parking will be provided in the Community Facilities Open Space District as required for the uses which may be located in that Open Space District. (4) The PUD shall provide Common Open Space adequate in terms of location, area and type of the Common Open Space, and in terms of the uses permitted in the PUD. The PUD shall strive for optimum preservation of the natural features of the terrain. The PUD proposes nearly seventy five percent of the total PUD acreage as some type of open space (zone district or open space easements) with all lots abutting open space areas. The majority of the residential building sites occupy the gentle slopes of the historic agricultural fields and pastures with a few building sites integrated into the native vegetation around the fringe of these fields where slope gradients allow. The road accessing the Upper Meadow neighborhood has been aligned to fit comfortably into the native topography and in some areas it may be possible to use boulder walls on the cut side of this road platform to reduce hillside disturbance. Clustering of the residential use in the historically cultivated areas of the site, results in the preservation of a vast majority of the natural terrain features of the property. The PUD open space uses include recreational playfields, children's play areas, picnic areas near Four Mile Creek, opportunities for neighborhood recreational uses in the area of the preserved historical ranch structures including the potential for a heritage ranch display, a preserved hayfield, asphalt and gravel pedestrian trails and extensive opportunities for casual nature trail type hiking. On the ridge at the north end of the Upper Meadow neighborhood, a small picnic shelter and observation deck are proposed to serve as destination point for hikers . The observation deck site offers views to Mount Sopris, the Roaring Fork Valley and the Flattops to the north. Although no specific proposals have been presented, there has been some casual discussion by a few area residents about the possibility of creating a "heritage ranch" educational facility utilizing the preserved ranch buildings and the retained hayfield east of Four Mile Road. The Applicant is committed to cooperate on making the "heritage ranch" a possibility subsequent to approval of the PUD if such is initiated by area residents. To accommodate the potential for a "heritage ranch" facility, the Elk Meadows PUD Zone Regulations include a Community Facilities Open Space Zone District in the area of the preserved ranch barns. This zone district attempts to anticipate the potential administrative, educational and recreational activities that might be associated with such a facility. This zone district also accommodates potential administrative, operational and recreational activities that may instrumental to the Elk Meadows homeowners association's responsibilities to the residents of the PUD. (5) The PUD shall provide for variety in housing types and densities, other facilities and Common Open Space. The Elk Meadows PUD Zone District Regulations describe two single family residential zone districts which vary in minimum lot size, required setbacks, coverage and floor areas ratio criteria. Although the minimum allowed lot size of the two single family residential zone districts only range from 11,000 square feet to 18,000 square feet, the typical building envelopes within these lots range from 6,300 square feet to in excess of 25,000 square feet 30 4.07.03 The PUD shall meet the following site plan criteria unless the applicant can demonstrate that one (1) or more of them is not applicable or that a practical solution has been otherwise achieved: (1) The PUD shall have an appropriate relationship to the surrounding area, with unreasonable adverse effects on the surrounding area being minimized. Surrounding uses are all residential in nature with lot sizes being as small as two acres but increasing up to greater than 35 acres in size. Residential development at Elk Meadows is proposed in three neighborhoods which are positioned internal to the PUD property such that they are buffered from any adjacent use by large expanses of open space, with one exception. The exception being the two acre single family residential lots located in the Four Mile Ranch Subdivision adjacent to and north of the East Meadow neighborhood. The uses are of course compatible and although the Four Mile Ranch single family lots are considerably larger than those proposed in the East Meadow neighborhood, the building envelopes of these two projects will be separated by 250 feet to 285 feet with over 200 feet of this distance being dedicated open space or open space easement. Portions of the development will be visible to the public from Four Mile Road and Hwy 82 and by residential properties in proximity to the PUD property. Efforts have been made to minimize and mitigate the visibility of the future resiE act inclu1ding avoidance of development of areas of greatest visual sensitivity. jSO�, A twenty acre hayfield will be preserved along Four Mile Road buffering the future East Meadow homes by distances of 400 to 800 feet and maintaining the continuity of open space currently found along Four Mile Road through the PUD property and on to the north through the Four Mile Ranch Subdivision. The hayfield will be maintained in irrigated agricultural production. This open space effect is continued south by the preservation of the two largest Bershenyi barns in the area being referred to as the "Barnyard" which will be landscaped and maintained as parkland. In the area of the existing Bershenyi homestead on the west side of Four Mile Road, proposed lots are set back from the Four Mile Road right-of-way by at least 50 feet and when combined with the rear yard areas the closest home will be at least 90 feet from Four Mile Road with most homes being well in excess of 100 feet from the roadway. Landscape plans for the Barnyard and the open space areas at the project entry and the open space buffer along the west side of Four Mile Road will be presented with the preliminary plan' application. C tx..67-ipeca. Other areas of development avoidance include the ridgelines to east and north of the Upper Meadow, which are highly visible from Glenwood Spring, the upper Four Mile Creek valley and Hwy 82. Also, the large meadow located north over the ridge from the Upper Meadow (Far North Meadow) is preserved as open space. The Far North Meadow is quite visible from south Glenwood Springs. Lots on the east side of the East Meadow neighborhood are pulled back away from the east ridgeline and proposed building envelopes push future residences even further away from the ridgeline. Specific tree planting requirements are included in the protective covenants, which will reduce the visibility of residential structures is this area as viewed from Hwy 82. The following cross sections provide an accurate graphic portrayal of the potential visibility of the future homes along the east edge of the East Meadow and how the proposed landscape 28 IN REPLY REFER TO: 1780 (CO -14000) Use � G Vz47 United States Department of the Interior BUREAU OF LAND MANAGEMENT Glenwood Springs Field Office 50629 Highway 6 and 24 P.O. Box 1009 Glenwood Springs, Colorado 81602 March 19, 2007 Mary Ray Garfield County Building & Planning Dept. 108 8th Street, Suite 201 Glenwood Springs, Colorado 81601 Dear Marv:• TAKE PRIDE" !NAM ERICA Thanks for the opportunity to comment on the The Reserve at Elk Meadows PUD. The BLM does have some specific private -public land interface comments relating to the proposed PUD. 1. Trespass The applicant should be mindful of the location of BLM property boundaries to ensure no encroachment occurs on public lands. The developer should clearly delineate, by fencing, the public - private land boundary to reduce trespass during construction and after the homes are occupied. 2. Trails and Access. Further discussion is needed on the proposed trail access (historic ranch access road)across BLM lands to the upper parcel of private lands. Preliminary review indicates that the road would be appropriate for public access as long as no improvements would be performed that would make it more visible or noticeable. Generally the trail system within the development should be maximized to lessen the impacts on public lands and all trails should be open to the general public. Public trailhead and parking facilities should be provided on private lands and constructed by the developer. Loop trail systems should be developed to eliminate trails that dead end at the public land boundary. 3. Fire Hazard Analysis All fuels reduction/breaks should occur within the boundaries of the PUD. In order to protect life and property, homes should not be built in areas where wildland fire protection requires vegetation management on the adjacent public lands. 4. Right-of-ways. Any roads, cart trails, paths, or utilities such as water, electric, phone or otherwise crossing BLM would require right-of-way (ROW) permits from this office. An environmental assessment of tl-ie impacts of those uses would be needed as a part of the ROW permiLLitig process. 5. Traditional Public Land Uses It should also be noted that traditional public land uses sometimes conflict with the expectations of new residents. The applicant should be aware of and respect the following values and existing uses of the adjacent BLM lands. a. Livestock Grazing. The applicant should be advised that the adjacent public land has current permits for livestock grazing. Under Colorado statutes, it is the owners' responsibility to construct, and maintain in good condition a lawful fence protecting their property in order to recover any damages from trespass livestock. If a livestock fence is not presently in place, a fence built along the private - public land boundary is recommended to reduce potential future problems. Should any fence construction be considered along the private/BLM boundary, the fence standards should allow for easy passage by big game. This office. can provide additional information regarding fence standards upon request. b. Recreation/Travel. The adjacent public lands are managed to offer a variety of dispersed recreational activities (motorized and non -motorized). Motorized and non -motorized travel is managed in accordance with the Glenwood Springs Field Office - Resource Management Plan. This broad range of activities will likely continue to occur contiguous to the private lands. Our office can provide additional information on recreation, travel and access as necessary. c. Hunting and Target Shooting. The adjacent BLM lands are open to hunting and target shooting. The BLM does not establish safety zones or no -shooting zones to restrict hunting. d. Mineral Rights. The Bureau has not researched the mineral rights to determine if they are reserved to the federal government on the subject lands. We are open to work with the developer and the Garfield County as necessary. If you or the developers have questions, please contact Brian Hopkins of my staff. He can he reached at (970) 947-2840 (FAX: 947-2829). Sincerely, Jamie E. Connell Field Manager PURPOSE AND SCOPE OF STUDY This report presents the findings of a geologic review of the 2006 conceptual development plan for the Reserve at Elk Meadows, County Road 117, Garfield County, Colorado. The project site is located about four miles south of Glenwood Springs, see Figure 1. The study was conducted to evaluate the geologic conditions in the project area and to assess if the geology could present potential constraints and risks to the 2096 conceptual development plan. The study was done according to our November 14, 2005 proposal to Reserve at Elk Meadows, LLC. This review is based on a field observation made in April, 2005 for our preliminary geologic site assessment (Hepworth-Pawlak Geotechnical, 2005a) and during follow-up field observations in November, 2005. In addition, we have reviewed published regional geology studies and looked at aerial photographs of the area and our previous work in the area. This report summarizes our findings and presents our conclusions and recommendations. PROPOSED DEVELOPMENT The 2006 conceptual development plan indicates that three residential areas, the East Meadow, the South Meadow and the Upper Meadow will be developed on the 500 acre Bershenyi and Martino Ranches, see Figure 2e en o single family residential lots are proposed in the East Meadow areagagalo. residential lots are proposed in the South Meadow area arid. fifty-five residential lots are proposed in the Upper Meadow area. The lots typically cover about 0.3 acres. Other development facilities will include a street system, public parking areas, recreational trails and a pond in the South Meadow area. The development will have a central water distribution system. The sewer system is proposed to be connected to the City of Glenwood Springs municipal system.

These properties are being proposed, in a separate application, to be rezoned as the Elk Meadows Planned Unit Development and are currently mapped largely as Residential Medium Density with scattered areas of Residential Low Density and on the Comprehensive Plan's Proposed Land Use Districts, Study Area I map. Much more complete Development Constraints information is now available and there have been changes regarding other Development Constraints and Land Use Considerations since the original mapping of the land use districts. The following evaluates the subject properties based on the currently available information using the criteria established by Table 30 of the Methodology Section of the Comp Plan This evaluation resulted in the mapping of the subject properties as High Density Residential and Medium Density Residential as shown on the plan included with this application. In general, the proposed map identifies the lower, gently sloping fields and meadows of the Martino and Bershenyi Ranches as being in the Residential High Density District due to the total lack of development constraints, the availability of central sewer service and proximity to an improved collector road and community services. The balance of these ranch properties are influenced by scattered areas of development constraints but they also benefit frOin central sewer service, proximity to good access and the Glenwood Springs community. These areas have therefore been mapped as Residential Medium Density. A summary of the Table 30 evaluation follows below. 1I. HIGH DENSITY RESIDENTIAL (one dwelling unit per 2 or Tess acres) A. DEVELOPMENT CONSTRAINTS 1. SLOPE CONSTRAINTS: Minor The areas mapped as High Density are almost completely dominated by very gentle slopes (less than 10%) with only a few narrow transition fringes exceeding 15% gradients. Slopes constraints in these areas are very minor or non existent. 2. SOILS CONSTRAINTS: Minor The vast majority of the High Density areas are comprised of old 1 stream alluvium with minor soils constraints. Depending on the character of the shallow subsurface soils some soils may have expansion potential and other areas may be hydrocompressive both of which can be mitigated with appropriate foundation designs based on building site specific soils investigation at the time of construction. 3. ISDS CONSTRAINTS: Minor While ISDS constraints in the High Density area are very minor, these areas have access to an exiting sewer transmission line located in Four Mile Road. This sewer line delivers effluent to the City of Glenwood Springs for treatment in their regional waste water treatment facility. The accompanying Elk Meadows PUD Application includes a Can and Will Serve Letter issued by the City of Glenwood Springs which provides for the treatment waste water from the Elk Meadows PUD upon satisfaction of certain conditions related to the City's adoption of a 201 Plan, the approval of a South Glenwood Springs Transportation Plan and payment for completion of certain traffic improvements. The property is included in the "area of service" in the City's current draft of the 201 Plan. The Can and Will Serve Letter also provides an outside date by which the City must define the required traffic improvements. The satisfaction of the various conditions of the Can and Will Serve Letter will ultimately be documented by the signing of a pre- annexation agreement with the City. The presence of the sewer interceptor line extending up the Four Mile Valley to points beyond the Elk Meadows PUD and the capability of the City of Glenwood Springs to provide sewer service to this area qualifies the described properties to be classified as having Minor or, in fact, no ISDS constraints. 4. FLOODPLAIN CONSTRAINTS: Minor Mapping of the High Density areas avoids all areas influenced flooding or debris flow and therefore there are no constraints related to this category. B. LAND USE CONSIDERATIONS 1. LAND USE COMPATIBILITY: Critical 2 The High Density areas are buffered by the areas mapped as Medium Density from all adjacent properties except for the Four Mile Ranch Subdivision located on the north boundary of the easterly hayfields of the Bershenyi Ranch. However, the lots at the south end of the Four Mile Ranch Subdivision are quite linear with the rear one hundred or more feet of these lots being overlain with an open space easement that buffers homes from the Bershenyi property. Giving current conditions, the gently sloping areas of the Four Mile Ranch would logically be designated as Residential High Density use if it were not already subdivided. 2. ROAD CONDITIONS: Critical These properties are served by Four Mile Road which is a collector road for the Four Mile valley. Redevelopment of this road in association with the Four Mile Ranch Subdivision improved the capacity and safety of the northerly end of Four Mile Road. Construction of the above described sewer interceptor in the Four Mile Road right-of-way has resulted in new asphalt surface and a realignment of Four Mile Road proposed by the accompanying Elk Meadows PUD Application will further improve the safety and carrying capacity of the road. This improved Four Mile Road from the subject properties north to the City of Glenwood Springs is more than capable to serve the High Density areas as proposed. The traffic study included with the Elk Meadows PUD Application addresses traffic conditions in the South Glenwood Springs area and identifies improvements in that area that would accommodate traffic at an acceptable level of service until approximately 2025. The recommended improvements are addressed in a proposed pre -annexation agreement which is one of the conditions of the City's Can and Will Serve Letter regarding sewer service. 3. INFRASTRUCTURE NEEDS: Critical This is a somewhat generalized category but as described above the area can now served by central sewer and has direct access to an enhanced collector road. Additionally, the Glenwood Springs Fire District has recently completed a new Fire Station at the north end of the Four Mile Ranch Subdivision about three quarters of a mile from the entrance to the proposed EIk Meadows PUD. The Sopris Elementary School is located just off Four Mile Road/Midland Avenue about one and one quarter miles form the EIk Meadows PUD Entry. A public pedestrian trail is currently in 3 place for about one third of the distance to the school and the proposed Elk Meadows PUD will complete an additional third that that distance. Critical infrastructure is in place to serve the identified High Density areas. 4. DISTANCE FROM URBAN USES: Moderate The close proximity of the Fire Station and elementary school are described above. In the same vicinity as Sopris Elementary School is the Mountain Market and associated commercial spaces offering convenience products, gasoline and personal service type businesses. The existing paved pedestrian trail paralleling Four Mile Road through the Four Mile Ranch Subdivision will be extended through the proposed Elk Meadows PUD making the school and Mountain Market convenience services more accessible for pedestrians. American National Bank, Rivers Restaurant, WalMart and the numerous other commercial services of South Glenwood begin at a point Tess than three miles from the subject properties. Urban services are readily available to the future residents of these properties either by vehicle or by foot. The location of the proposed High Density districts easily satisfies a Moderate ranking for proximity to urban uses. SUMMARY: The above clearly describes how the proposed High Density areas comply with the designated rankings for Development Constraints and Land Use Considerations. III. MEDIUM DENSITY RESIDENTIAL (ONE DWELLING UNIT PER 6 - 9 ACRES) A. DEVELOPMENT CONSTRAINTS 1. SLOPE CONSTRAINTS: Moderate In their report dated August of 2005, HP Geotech classified the slopes (Slope Stability Class Areas) in over thirty percent of the area that is proposed for Medium Density as being suitable for most types of development. The remainder of the acreage was described as not recommended for high density development but as being suitable for low density residential development at some locations with careful site selection. Consideration of rock fall hazard seems appropriate to this section and a small zone of rock fall hazard has been mapped on the west central edge of the 4 property totally four percent of the area proposed as Medium Density. Given its small size and location, this rock fall zone has relatively little impact on the overall development capacity of this Medium Density district. The diversity of the slopes in the proposed Medium Density area, ranging from moderately steep to gentle, is consistent with an average ranking of Moderate for Slope Constraints. 2. SOILS CONSTRAINTS: Moderate Actual foundation soil conditions found in the proposed Medium Density areas is not much different from the potentially expansive soils and hydrocompactive soils found throughout the entire site. These conditions may require some level of mitigation through engineered foundation designs based on site specific investigations conducted at the time of residential construction. These types of soil conditions are very common in this region and are consistent with a Moderate ranking for Soil Constraints. 3. ISDS CONSTRAINTS: Moderate Although the soil conditions throughout much of the Medium Density area offer little constraint to the use of individual sewage disposal systems, the availability of central sewer service to the entire site makes consideration of ISDS Constraints a mute analysis. 4. FLOODPLAIN CONSTRAINTS: Moderate There are some flooding constraints in the Medium Density area that are primarily confined to the immediate Four Mile Creek area, a side channel and an area that coincides with the rock fall hazard zone discussed above. The total area of impact is relatively quite small as compared to the total area of the proposed Medium Density district and is largely isolated by the steep valley walls adjacent to Four Mile Creek_ Given the flood free characteristics of the vast majority of the proposed Medium Density area, flooding and debris flows represent a very minor constraint to this area. B. LAND USE CONSIDERATIONS All testimony offered regarding Land Use Considerations in the High Density section above are equally as applicable to the area proposed as 5 Medium Density and therefore are not repeated below. The justification offered for the High Density category above was proposed as appropriate to satisfy a "Critical" level of consideration and therefore is more than adequate to satisfy the "Moderate" and "Minor" considerations for a Medium Density classification. 1. LAND USE COMPATIBILITY: Moderate Refer to the previous High Density discussion. ROAD CONDITIONS: Moderate Refer to the previous High Density discussion. 3. INFRASTRUCTURE NEEDS: Moderate Refer to the previous High Density discussion. 4. DISTANCE FROM URBAN USES: Minor Refer to the previous High Density discussion. SUMMARY Although the proposed Medium Density district is comprised of a diversity of physical characteristics, when considered in the average or median condition, the Development Constraints are consistent with the Medium Density category. The availability of urban services, infrastructure and access easily exceed the expectations of the Land Use Considerations for the Medium Density category. 6
