GENERAL PROJECT DESCRIPTION SUMMARY The overall design scheme for TCI Lane Ranch is based on the concept of compact or clustering, allowing for the preservation and dedication of over 75% of the site as open space through sustainable development techniques. Current and historic uses of the property include ranching irrigated meadows and three log structures which will be preserved as recreational amenities. TCI Lane Ranch is the Owner of the 100.52 acres TCI Lane Ranch (the Property) which has submitted the development application to Garfield County. The proposal is to develop the site into six (6) distinct neighborhoods, which incorporates a mixed residential community including 89 residential units of duplexes and single-family detached units. These units vary from 1,900 square foot attached duplex homes to 5,500 square foot single family homes. The access to the Property is by way of County Road 100 and State Highway 82 frontage road, physical water is to be provided by Mid Valley Metropolitan District, and wastewater is also to be handled by Mid Valley Metropolitan District. In order to accomplish the proposed development, TCI Lane Ranch, LLC requests approval for 1) Rezone from ARRD to Planned Unit Development (PUD) and 2) Preliminary Plan Approval. II. REVIEW AGENCY COMMENTS The Applicant sent the proposal to the following review agencies whose comments are provided below and are incorporated in the memorandum where appropriate: A. Town of Carbondale: Assessment targeted the environmental preservation aspects of the development including wildlife fencing, appropriate planting of buffer vegetation and minimum disturbance of the Ute Ladies' Tresses, a wetland orchid within the development. Impacts on the intersection of County Road 100 and State Highway 82 frontage road in terms of level of service during peak hours, construction in the 100 year floodplain, density zoning regarding site access and safety and the construction of the footbridge across the Roaring Fork River are impacts of concern with the Carbondale Planning Commission. Commendable aspects of the project centered upon the preservation of open space and the net zero energy plan. (Exhibit G) B. Mt. Sopris Soil Conservation District: No Comments Received C. Eagle County: Indicated that TCI Lane Ranch has a lot of creative and innovative sustainable design techniques. These included the open space area allocations, a buffer zone between Highway 82, an active solar farm array, a community center for active recreational use, pedestrian connections to the Catherine's 0A Store intersection and deed restrictive housing. Areas of concerns included; construction within the 100 year floodplain and its impact on the wetlands, the allowable amount of square footage of inclusionary affordable housing, reduction of roadway widths, the potential level of service degradation at the intersection of County Road 100 and State Highway 82 frontage road in the future, no passive solar housing design, wildlife fencing, the inclusion of a townhome cluster and more housing design diversity. (Exhibit H & 1) D. RE -1 School District: No Comments Received E. Bureau of Land Management: Commented that TCI Lane Ranch build a secured fence around the BLM parcel to prevent public access. Reason given: sensitive wetland plants (Ute Ladies Tresses) are throughout the parcel. (Exhibit J) F. Carbondale Rural Fire Protection District: Indicated that the proposed accesses throughout the development appear to be adequate for emergency apparatus. Residential dwelling units are proposed up to 5,500 square feet and would require fire flows of up to 2000 gallons per minute (GPM). The proposed system appears capable of providing adequate flows with 2000 gallons per minute flows requiring decreased spacing of the fire hydrants. (Exhibit K) G. Colorado Department of Transportation: Found that the traffic study recommends intersection improvements at State Highway 82 and County Road 100. The study recommends an additional northbound right turn lane on CR 100 and an additional northbound left turn lane on CR 100 (double left) in the future. But the study states that the northbound right turn lane is needed without project traffic. The Access Code states an access permit is needed when the traffic volume is over 20% while the TCI Lane Ranch development will only increase the traffic volume by less than 5%. An access permit is not needed at the CR 100 connection for this project. (Exhibit L) H. Colorado Division of Wildlife: Because the proposed development is adjacent to important elk and deer winter range on the south side of the Roaring Fork River, the development will have direct and indirect impacts on wildlife. The suggestive mitigation measures should be taken such as: plantings of native vegetation are encouraged for deer and elk so conflicts can be minimized; eliminate any berry, fruit, or nut producing plants or shrubs to discourage elk, deer, bears and other wildlife from feeding on the artificial landscaping. Other concerns included minimizing vegetative removal in the wetland areas; proposed trails/paths need to be minimized and public access should be limited into wildlife -sensitive areas; take aggressive measures to reduce bear and human conflicts such as bear - proof container for storing all trash/garbage, pet feeding, outside BBQ cleaning and round door knobs instead of leaver type; build wildlife friendly fencing; place all utilities underground and remove any dead wildlife from the property if present. These issues need to be stated in the Covenants, Conditions and 3 Restrictions (Exhibit M) Colorado Division of Water Resources: Evaluation was based on the existing water resources. Because Mid Valley Metropolitan District is providing the water supply and wastewater disposal services to the site, water concerns need to focus upon irrigated water from decreed surface water rights, which must not result in the expansion of its usage. Section 37-92-602 (3)(b)(III) C.R.S. requires that the cumulative effect of all wells in a subdivision be considered when evaluating material injury to decreed water rights. The application indicates that the existing ditch water rights will be used on historically irrigated lands, for individual lots, for water features and for the creation of wetlands. With the Roaring Fork River as an over appropriated stream system, wetlands mitigation must be at a one-to-one ratio as opposed to a two -to -one ratio because created wetlands may expose groundwater which necessitates a well permit. Most importantly, the State Engineer stated that "since insufficient information was provided, we cannot comment on the potential injury to existing water rights... Note that the use of irrigation water rights must not result in an expansion of use, and approval of a change of water right application by the water court may be necessary if the place or type of use is changed." (Exhibit N) J. Mid -Valley Metropolitan District: No Comments Received. A letter of intent to service the development was included within the application. K. Colorado Geologic Survey: Stated that the major impacts will be within the 100 - year floodplain or "fringe" area by way of a flooding event and sinkhole potential. Mitigation should center upon the designed finished floors being at least 1.5 feet above base flood elevation with the implementation of hard engineering techniques such as rip/rap armoring around the pad areas and road systems within the flood zone. Sinkholes are of less concern but center upon construction or pad stability, homeowner awareness of potential hazard, early detection of building distress and remedial measures to offset any preventative damage from an undetected subsurface void. (Exhibit O) L. Garfield County Road & Bridge Department: Garfield County Road & Bridge Department has no objections with the TCI Lane Ranch application. The pedestrian and emergency vehicle access leading to CR 100 from Blue Creek would not present a traffic issue on the total volume of traffic on CR 100. Thus, no access permits would be needed from Garfield County Road & Bridge Department. (Exhibit P) M. Colorado Department of Public Health & Environment: No Comments Received N. Roaring Fork Transit Authority: Recommends further examination of future transit upgrades and improvements to Catharine's Store "park and ride" facility. RFTA is satisfied with the proposed pedestrian bridge over the Roaring Fork River to connect with the Rio Grande Trail and feels the bridge will be an asset to the 11 community, further promoting seasonal usage of the Rio Grande Trail. TCI Lane Ranch is planning to build the pedestrian bridge in 2010, after major infrastructure has been complete and the sale of some lots will allow for that capital improvement to be made. (Exhibit Q) O. US Army Corps of Engineers: No Comments Received P. Garfield County Vegetation Manager: Assessment focused on the impacts to the wetlands and weed control. Wetland issues revolve upon a "dry period" wetlands delineation, the Ute's Ladies Tresses (Spiranthes diluvialis) orchid, which is a federally listed threatened plant species, constructed trails within the wetlands, the site design/alignment of Mayfly Bend, Riverstone Drive and Dragonfly Spur to minimize the impacts on the orchid and to disallow landowners from adding fill material into designated wetlands within their lots. Staff encourages the applicant to follow the weed management plan provided and have it is written into the Subdivision Improvements Agreement to guarantee that weed management will occur in the future on undeveloped lots and for the open space areas. Additional comments focused on the soil management plan as being acceptable and to address the issue of mosquito management in the neighborhood constructed wetlands area. (Exhibit R) Q. Garfield County Housing Authority: Provided comments related to nine (9) units of affordable housing that are required under section 4.07 of the Garfield County Affordable Housing Guidelines. These units are to be administered in accordance with section 4.14 of the guidelines but only six (6) of the units meet County guidelines. Thus, three (3) of these units would not be administered by an approved housing agency. (Exhibit S) R. Garfield County Sheriff Department: No Comments Received S. Garfield County Engineering: Provided comments related to roadway design citing recommended issues of layout and grades, road and shoulder widths and on street and public parking. Also, comments were related to preliminary plat preparation, drainage and erosion control, environmental permits related to water resources, off site water and sewer, the legal source of water and financial guarantees for revegetation. (Exhibit T) T. Holt/ Cross Energy: Indicated they had existing power facilities on and near the project area and adequate power to supply the development. Any power line enlargements, adjustments or new extensions necessary will be undertaken by Holy Cross Energy for the development by way of the completion of necessary contractual agreements and governmental approvals. (Exhibit U) 5 III. RELATIONSHIP TO THE COUNTY'S COMPREHENSIVE PLAN 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 Master / Comprehensive Plan." The following section will review the proposed PUD against the County's Comprehensive Plan. [As you will recall, the Planning Commission previously amended the Comprehensive Plan's Proposed Land Use District map for the property from "Low Density Residential" to "High Density Residential". This was done primarily done with an analysis of using the methodology of Table 30. The development averages out at 1.2 acres per unit would be congruent with the abutting and surrounding properties; i.e. Aspen Equestrian Estates at 1.2 acres per dwelling unit and Blue Creek Ranch PUD at 1.6 acres per dwelling unit. The proposed PUD's density and residential land use are consistent with this High Density Residential designation.] There are general concepts of the proposed PUD that do generally conform to the Comprehensive Plan including the following: 1. Protecting Visual Corridors — The proposed design includes preservation of cultural resources and open space protecting the identified visual corridor of Highway 82. Ranching and livestock activities will be continued on a seasonal basis adjacent to Highway 82. 2. Creative Sustainable Design — The development as represented by six (6) clustered or compact residential development neighborhoods preserving both active and passive open space and riparian vegetation through wetland sensitivity. 3. Open Space — The plan includes multiple open space areas throughout the development, which amounts to over 75%. 4. Public Transportation — The proposed development is located approximately one-half a mile from a RFTA park and ride facility, which is indicative of a transit -oriented development. 5. Public Park for River Access — Preserving over thirty two (32) acres of open space located adjacent to the Roaring Fork River, which will be open to the public through the Roaring Fork Conservancy. Six (6) public parking spaces will be provided for fishing only. 6. Bike and Pedestrian Trail - The Applicant is in the process of receiving the 32.30 acre conservation easement from the Roaring Fork Conservancy to establish bike pathways, connecting trail systems and fishing access. G IV. COMPREHENSIVE PLAN Goals, Objectives & Policies The following section will review the proposed PUD with the following applicable Goals, Objectives, and Policies of the Comprehensive Plan. A. SECTION 2.0: HOUSING GOALS ➢ To provide all types of housing that ensures current and future residents equitable housing opportunities which are designed to provide safe, efficient residential structures that are compatible with and that protect the natural environment. ➢ Housing at cost of no more than 30% of gross median income. ➢ Designate appropriate areas. ➢ Encourage mix of housing types within a development. ➢ Deed restrictions placed on the title to fix increase in value of a home. OBJECTIVES 2.1 To encourage adequate, integrated housing at a reasonable cost to residents throughout Garfield County. 2.2 to ensure construction of quality housing by continued enforcement of the County's building code. 2.3 Residential development should be designed and located to ensure compatibility with existing and future adjacent development. 2.4 The County should encourage the development of energy efficient design, including solar access. 2.5.1 Residential development should respect the natural characteristics of a particular site, including topography, vegetation, water features, geology and visual relationships with surrounding land uses and view sheds. 2.5.2 The County should coordinate efforts with the Garfield County Housing Authority and respective municipalities to foster regional housing goals. 7 POLICIES 2.1 The County, through the development of regulations, shall provide for low and moderate housing types by allowing for mixed use multi -family and single-family housing in appropriate areas throughout the County. 2.4 Solar orientation that allows for both passive and active design will be strongly encouraged in the design review process and will not be restricted by protective covenants. Staff Response The affordable housing units proposed within the development will be dispersed and incorporated throughout the six (6) individual neighborhoods which meet a mix of housing types. The Application proposes to convey 10% (or nine units) to the Housing Authority as resident occupied deed restricted units. These are single-family units on lots 1, 11, 12, 18, 25, 26, 28, 29, and 39. This meets the County's affordable housing requirements. Additionally, (while not required) the Applicant proposes five (5) additional units that are privately administered for employees. The Garfield County Housing Authority reviewed the original proposal and provided the following comments related to affordable housing. (Note, the revised application binder addresses these concerns.) It is Garfield County Housing Authority (GCHA) understanding that the nine (9) units of affordable housing are required under section 4.07 of the Garfield County Affordable Housing Guidelines. These units are to be administered in accordance with Section 4.14 of the guidelines. The proposal for Lots 1, 10, 11, 24, 25 and 28, as stated in the application, clearly meets the County guidelines. However, we have the following concerns for the proposed Lots 81, 38 and 27: 1. These units would not be administered by GCHA or by an approved housing agency. 2. There is no guarantee that these units will be occupied by employees within Garfield County. 3. County forfeits three (3) units to the corporations of Holy Cross Energy, the Roaring Fork Conservancy and the Roaring Fork Transportation Authority. 4. Eligibility requirements cannot be guaranteed. 5. There is no guarantee that the units will go through the County lottery or that any lottery would be conducted in accordance with County guidelines. 6. There is no guarantee that the resale of these units will be conducted according to the County guidelines. 7. It appears that Lots 81, 38 and 27 will be utilized at the sole discretion of the corporations that they are to be conveyed too without regard to the County Guidelines. Therefore, these three (3) units should not be applied to the required nine (9) affordable units. 8. The developer is to be commended for the plans to provide an additional five (5) units for employee housing through Lots 17, 36, 37, 66 and 89. While employee housing does not automatically equate to affordable housing nor comply with the County Guidelines they are a welcome benefit. 9. The proposal states that the developer will convey the units to the Garfield County Housing Authority. Garfield County Housing Authority points out that GCHA will not take possession of the units. It is the responsibility of the developer to complete the initial sale of the units. 10. The application includes a sample deed restriction that could be recorded with these units. Garfield County Housing Authority would like to see a more thorough and consumer friendly deed restriction recorded. 11. The proper deed restriction recordation is paramount to the future of the affordable housing units. All deed restrictions must be approved by the GCHA as well as the County legal department. GCHA is willing to provide an appropriate template for the deed restriction. 12. The applicant states that the affordable units, which include three (3) units to corporations, five (5) units of employee housing and six (6) units, not nine (9) for the County's program, will be eight (8) duplex units and six (6) single-family units. It is not clear to the GCHA what the mix of duplex and single family units will be built to satisfy the required nine (9) units of affordable housing. Eagle County Planning Department reviewed the proposal and provided the following comments related to affordable housing: 1. It appears from the land use summary that a total of 31,000 square feet of affordable housing will be provided within the TCI Lane Ranch project. While Eagle County commends the inclusionary nature of these affordable housing units interspersed throughout the project, it would fall short of any of the options listed in Exhibit X for compliance with the Eagle County housing guidelines. 2. Housing types could be further differentiated to improve the inclusionary I nature of the project. Eagle County recommended the possibility of including a townhome cluster, as well as accessory dwelling unit allowances, on single- family homes. This has been shown to be beneficial dispersed rental stock in their communities. In summary, Staff finds the revised proposal meets the County's affordable housing requirements for unit and bedroom count and that the concerns of the Garfield County Housing Authority can be met. Staff discussed this revision with the GCHA and they support this new approach. The Code allows for a "security" provision to ensure the units are built while the free-market units are being built. This could be in the form of a cash security (letter of credit) or a provision to withhold issuance of building permits on free-market units until a building permit has been issued for a deed -restricted unit generally at a ratio of 10 free-market to one (1) deed restricted unit. In this case, the application proposes these 9 units will be constructed at a rate which will be a minimum of 10% affordable to 90% market rate at any one time. Staff suggests using the 1 to 10 ratio language for ease of administration as follows: "In order to ensure the orderly and timely construction of the 9 required deed - restricted affordable housing units, no more than 10 free market unit building permits shall be issued by the Garfield County Building and Planning Department at any one time unless a building permit has been issued for a deed -restricted affordable housing unit such that a ratio of free-market to affordable housing units shall be constantly maintained of 10 free-market to one (1) deed restricted unit." Staff finds this approach meets the Comprehensive Plan. Also, because the Final Plat will most likely be tendered to the County under the provisions of the new land use Code (Unified Land Use Resolution of 2008), the requirement for 15% affordable housing will not likely be applied to this application as the Preliminary Plan and PUD were reviewed under the old land use code. [Recall, a text amendment is being processed presently to alleviate this requirement for applications that straddle the twp codes.] B. SECTION 3.0: TRANSPORTATION GOALS ➢ To ensure that the County transportation system is safe, functional, appropriately designed to handle existing and future traffic levels and includes options for the use of modes other than the single -occupant automobile. ➢ Determine appropriate nodes and collector points for public transportation. 10 Staff Response The transportation challenge of this project will be the impact of the development on State Highway 82 and County Road 100 as the majority of traffic from the development will use this intersection. This intersection is heavily used as the alternate route to the Town of Carbondale or up valley destinations and concerns have been raised about the ability of the intersection to absorb additional traffic in the future. The concern pivots upon the point that there could be potential stacking of vehicles on the frontage road. Also, with the apparent number of bicyclists that use the frontage road, conflicts between bicyclists and vehicles on the frontage road should be an issue addressed for safety and road access. With the proposed construction of a pedestrian bridge across the Roaring Fork Bridge, this will facilitate easy bicycle travel to the Town of Carbondale and to destination points throughout the valley. The revised application proposes certain improvements to the intersection of State Highway and CR 100 that are acceptable to both Garfield County and CDOT and satisfy this goal. This is better described below. OBJECTIVES 3.1 To encourage the development of a regional public transit system that respects the interaction between emerging land use patterns and travel behavior in the Valley. 3.2 To encourage the use of modes other than the automobile. 3.3 Proposed developments will be evaluated in terms of the ability of County roads to adequately handle the traffic generated by the proposal. 3.4 Proposed developments will include street designs that will reduce adverse impacts on adjacent land uses, respect natural topography and minimize driving hazards. 3.7 Street extensions will be required to occur in a logical manner. Staff Response The PUD Plan does propose both pedestrian and bike trails throughout the plan. Staff finds the Property lends itself well to running and biking trails throughout the development with access to the Rio Grande Trail. TCI Lane Ranch has both walking and riding access to the Roaring Fork Transit Authority (RFTA) "park and ride" facility at Catherine's Store, approximately %2 a mile from the site, which makes it convenient for residents to commute by bus. RFTA has recommended this local shuttle service area be enhanced with additional parking and the realignment of State Highway 82 frontage road into RFTA's regional service. Regarding internal circulation, the originally proposed site plan included two dead-end cul-de-sacs longer than the permitted length of 600 feet along Mayfly Bend to Stonefly 11 Loop. The revised application eliminated one cul-de-sac altogether and reduced the other to meet the County's requirements. The plan has two separated entrances / exits in and out of the project for normal traffic flow as well as an emergency access route through Blue Creek Ranch at the far west boundary of the project. These revisions to the site plan have produced an internal circulation plan that meets the land use code and intent of the Comprehensive Plan. Regarding external off-site road impacts, the only road serving TCI Lane Ranch is the State Highway 82 frontage road. The intersection of State Highway 82 and County Road 100 is the primary intersection vehicles will use when accessing TCI Lane Ranch. In its present condition, the intersection of State Highway 82 and County Road 100 cannot sustain the current volume of traffic during peak hour volumes. The increased level of service which would result from the proposed TCI Lane Ranch residential development would diminish, even though an increase of only 5% volume in traffic will occur from this development. The Access Code states an access permit is needed when the traffic volume is over 20% from a given development. Upon development, TCI Lane Ranch is expected to generate a total of 784 trips during average weekday. It includes 14 inbound and 47 outbound trips during the morning peak hour and the evening peak hour would add an estimated 51 inbound and 30 outbound trips. Thus, the development will only increase the traffic volume by less than 5%. Therefore an access permit is not needed at the County Road connection for this project. CDOT does not have any process to make the developer address this need for intersection improvements. The addition of the project generated traffic should not have a potentially significant impact on the roadway facilities upon the project completion. If historical traffic growth rates persist in the vicinity of TCI Ranch, significant improvements may be required to maintain an acceptable level of service in and around the intersection of State Highway 82 and County Road 100. But these improvements are required today, even without the development of TCI Lane Ranch. The intersection at State Highway 82 and County Road 100 is not within any of the County's Traffic Impact Fee Zones. It has been recommended to Staff by referrals that the County, through the land use process, does have an ability to address this impact to the majority of the road users in the area and that the County should consider it as a condition of approval for TCI Lane Ranch. The revised application proposes to make certain specific improvements designed by Drexel, Barrell & CO that have been reviewed by CDOT which will ultimately result in a right turn lane from northbound CR 100 to the up valley direction of Stet Highway 82. Additionally, the applicant will construct a raised median between the northbound and southbound directions on CR 100 (within the SH82 ROW) adding additional safety to the turning movements. These improvements are to be paid for exclusively by the developer within the context of the Improvements Agreement and represents their fair 12 share of needed improvements. Regarding public transportation, transit within the vicinity is served by the Roaring Fork Transportation Authority (RFTA), which operates a route running between the towns of Aspen and Glenwood Springs along State Highway 82. The up valley route parking and bus stop is located at the southeast corner of the intersection of State Highway 82 and County Road 100. The down valley stop is located at the northeast corner of intersection State Highway 82 and County Road 100. This development is within walking / biking distance of this park & ride facility. POLICIES 3.2 Developments are encouraged to integrate bikeways, pedestrian circulation patterns and transit amenities into project design. 3.3 The project review process will include a preliminary assessment of the projected traffic impact associated with all commercial projects and residential projects greater than 50 dwelling units. 3.6 Development proposals will be required to mitigate traffic impacts on County roads proportional to the development's contribution to those impacts. Mitigation may include, but not be limited to the following: A. Physical roadway improvements; B. Intersection improvements.- C. mprovements;C. Transit amenities; D. Signage requirements; E. Alternative traffic flow designs; and F. Funding mechanism to implement necessary mitigation. Staff Response The project does include an overall trail system into the design to accommodate bikers and pedestrians. The PUD proposes a pedestrian bridge from TCI Lane Ranch to the Rio Grande Trail across the Roaring Fork River. Otherwise, bikers and pedestrians will be required to use the State Highway 82 frontage road. The interior design of the road system avoids impacts to the natural features. Roadways have been designed to minimize driving hazards by way of curvilinear roads which reduce speed and with two primary access points and one emergency access to provide adequate circulation and emergency service. The connection to the Blue Creek Ranch PUD to the west has been as an emergency and pedestrian access only. The emergency access will be blocked off with collapsible or break away bollards. In summary, Staff finds the project will generate some impact (5%) to the intersection of State Highway 82 and County Road 100. As a result, the Applicant intends to make improvements that have been approved by CDOT to make the intersection safer and 13 more functional. Staff finds the proposal adequately addresses the needed improvements to the road network to handle such a residential development. (It should be noted, the Applicant intends to propose a text amendment that allows for fair -share contributions / cost recovery or reimbursement of improvements fronted by a developer.) 5.0 RECREATION AND OPEN SPACE GOALS ➢ Garfield County should provide adequate recreational opportunities for County residents ensure access to public lands consistent with BLM/USFS policies and preserve existing recreational opportunities and important visual corridors. ➢ Interconnect trail system through the county with community trail systems. ➢ Extend trail system along river corridors. OBJECTIVES 5.1 Encourage the location of active recreational opportunities that are accessible to County residents. 5.2 The County will support and encourage the creation of open space, through the development and implementation of zoning, subdivision and PUD regulations designed to retain and enhance existing open space uses. 5.3 Access to public lands will be expanded and maintained. 5.4 Rafting and fishing access will be strongly encouraged during the development review process. 5.5 Visual corridors are considered an important physical attribute of the County and policies will reflect the need to carefully plan these areas. 5.6 Noise, parking and accessibility will be major concerns. 5.7 Encourage interaction between county/community. POLICIES 14 5.1 Developments that propose densities above one (1) dwelling unit per acre and exceed 50 dwelling units will be required to provide adequate recreational opportunities to serve the residents of the project. Alternatives for meeting this requirement will be defined in the Subdivision Regulations. 5.2 Important visual corridors will be identified and appropriate policies developed to address the retainment of open space areas that link communities in the County. 5.3 if physically possible, subdivisions and PUDs will be encouraged to design open space areas to become contiguous with existing and proposed open spaces adjacent to the project. 5.4 Consistent with the management objectives of either the Bureau of Land Management or the U.S. Forest Service, development next to public lands will be encouraged, but not required, to provide public access easements without the use of condemnation processes. 5.5 With the cooperation of the Division of Wildlife, developments proposed in areas next to streams or rivers with rafting or fishing potential should dedicate easements for public access to these areas. 5.6 In order to encourage public access to rivers, streams and public lands, the County will be receptive to incentives, consistent with an overall program approved by the Board of County Commissioners, for developments that propose public access to these amenities. 5.OA OPEN SPACE AND TRAILS GOAL ➢ Garfield County shall develop, adopt and implement policies that preserve the rural landscape of the Roaring Fork Valley, existing agricultural uses, wildlife habitat and recreational opportunities in a mutually beneficial manner that respects the balance between private property rights and the needs of the community. OBJECTIVES 5.1A To ensure that existing agricultural uses are not adversely impacted by development approved by Garfield County; 5.2A To ensure that wildlife habitat is a component of the review process and reasonable mitigation measures are imposed on projects that negatively impact critical habitat, 15 5.3A That the development of passive and active trails in the County should be developed in a comprehensive fashion, consistent with efforts by adjacent jurisdictions; 5.4A That all long-range planning for the retention of open space, trails, agricultural lands and wildlife habitat shall respect property rights and the concept of just compensation; 5.5A That long-range planning for acquisition or dedication of open space and trails shall run parallel to efforts to develop funding sources for just compensation. POLICIES 5.1A All projects approved adjacent to existing agricultural uses shall be required to mitigate any adverse impacts. These mitigational measures shall include some or all of the following: 1. Appropriate buffering of building envelopes from common property boundaries; 2. The use of open space to provide additional buffering; 3. Dog restrictions, including limiting the number of dogs and requiring kenneling, prior to issuance of a Certificate of Occupancy. 5.2A Developers proposing projects located in areas defined as critical habitat by the Colorado Division of Wildlife Resource Information System (WRIS) will be required to propose mitigational measures during the submittal of proposed projects. Mitigational measures shall include the following: 1. Fencing and dog restrictions consistent with DOW recommendations; 2. Avoidance of critical portions of the property, through the use of building envelope restrictions or cluster development concepts; 3. Conservation easements. The Board of County Commissioners shall have the authority to approve or reject proposed mitigation. Staff Response The current and historic uses of the property include ranching with irrigated meadows and residential dwellings. Various outbuildings once associated with typical ranching operations, include the preservation of three log structures. These include a timber 16 barn, which will become, through adaptive reuse) the Community Center building for residents to hold meetings and events plus, act as a small recreation center and Homeowners Association Office. The two other minor log structures will be preserved as a visual resource and be utilized as storage facilities. A comprehensive system of trails has been designed as both a recreational amenity and to promote an alternative to motorized transportation. Trail links have been provided to both the RFTA transit "park and ride" and to the Rio Grande Trail by way of a pedestrian bridge over the Roaring Fork River. A proposed system of trails has been created for a variety of uses including paved asphalt trails, compacted soft surface pathways and natural surface or primitive trails. A dedicated right-of-way within the low volume street system serves as a secondary or improved trails system for both bicycles and pedestrians. Division of Wildlife reviewed the proposal and provided the following comments related to recreational amenities: 1. The proposed pedestrian bridge over the Roaring Fork River should be gated to prohibit access to the RFTA during the winter closure period. Staff feels this needs to be written into the Covenants, Conditions and Restrictions. 2. Due to the critical nature of wetland areas for wildlife, it is recommended that any proposed trails or paths be minimized and the public access into these areas should be limited in numbers. Access should be closed completely from December 1 through March 15 in order to limit the disturbance on big game and wintering bald eagles utilizing the riparian corridor. Staff feels this needs to be written into the Covenants, Conditions and Restrictions. Garfield County Vegetation reviewed the proposal and provided the following comments related to recreational amenities: • Where trail design indicates that the trail crossing the wetland area will be a 2' Natural Surface Path, Staff requests further clarification on this type of path. Garfield County Vegetation discourages the construction of any type of trail that would bring imported fill material into the wetland area. Town of Carbondale reviewed the proposal and provided the following comments related to recreational amenities: 1. The Town appreciates the pedestrian and bicycle connections and suggested that the County be sure that those concepts remain intact through the process. The City also appreciates the Open Space concept and asks that the concept also remain in place. The City commended the development as far as the net zero energy plan. 17 2. The Town discussed the impacts on the pedestrian bridge to the Roaring Fork River and asked that those impacts be assessed. The City assumes that the Army Corp of Engineers will be consulted prior to any construction. 3. The Town asked that the Roaring Fork Valley Planning Commission be consulted as part of the land use process for the TCI Lane Planned Unit Development. Eagle County Planning Department reviewed the proposal and provided the following comments related to recreational amenities: • The pedestrian trail connections between neighborhoods within the development are commendable. However, it appears there is no trail connection from the Dragonfly Spur, which seems like a logical additional connection. In summary, Staff believes the recreational and open space issues are minor. Staff concurs with the reviews where they state a "minimum disturbance/minimum maintenance" approach to the construction of pathways or trails through the wetlands areas. Staff recommends that, where possible, keep as much of the trail system in as natural state as possible by way of "soft engineering" techniques. And, if needed in areas of sensitivity, use a raised walkway as your surface travel mode through the areas of known Ute's Ladies Tresses (Spiranthes diluvialis) orchids. Area acres Open Space Use 0.98 Community Utility Zone District 33.30 Private Common Open Space 32.40 Conservation Easement 3.09 Community Center 7.0: WATER AND SEWER SERVICES GOALS To ensure the provision of legal, adequate, dependable, cost-effective and environmentally sound sewer and water services for new development. OBJECTIVES 7.1 Development in areas without existing central water and sewer service will be required to provide adequate and safe provisions for these services before project approval. 7.2 Development located adjacent to municipalities or sanitation districts with available capacity in there central water and sewer systems will be strongly encouraged to tie into these systems. 18 7.3 Projects proposing the use of /SDS will be required to access the site's capability to accommodate these systems prior to project approval. 7.4 Development will be required to mitigate the impact of the proposed project on existing water and sewer systems. 7.5 Garfield County will strongly discourage the proliferation of private water and sewer systems. 7.6 High-density development, defined as exceeding one (1) dwelling unit per one (1) acre, will be required to assess the potential of connecting into existing central water and sewer facilities. Staff Response The project area will be served by connecting to the Mid Valley Metropolitan District sewer and water service. Mid Valley Metropolitan District has indicated verbally and by way of letter that it has the capacity to accommodate the TCI Lane Ranch development. Based on the Goal and Objectives above, Staff finds that 1) there is an existing system in the area for this development to tie into, 2) the proposal provide adequate and safe provisions for these services, and 3) the private water / wastewater is strongly discouraged in Garfield County. The proposal does conform to these objectives. POLICIES 7.1 All development proposals in rural areas without existing central water and/or sewer systems will be required to show that legal, adequate, dependable and environmentally sound water and sewage disposal facilities can be provided before project approval. 7.2 Where logical, legal and economic extension of service lines form and existing water and/or sewage system can occur, the County will require development adjacent to or within a reasonable distance, to enter into the appropriate agreements to receive service. The burden of proof regarding logical, legal and economic constraints will be on the developer. 7.5 High density development is considered urban in nature and requires appropriate services. Through the Zoning Resolution, Garfield County will strongly encourage high-density development to locate in areas where these services are available. Staff Response 19 As mentioned above, the PUD proposes a density of about 1.2 dwelling units per acre, which exceeds the one (1) dwelling unit per one (1) acre and is qualified as "high- density" discussed in the policy above. The Policy envisions this type of density to occur in urban areas where there are appropriate services. Staff finds that a development is located Y2 mile from the Cerise Ranch development connection point for both water and sewer services. Through a very thorough review, the plan to provide central water and sewer from Mid -Valley Metropolitan District is consistent with the provisions in the Comprehensive Plan. 8.0: NATURAL ENVIRONMENT GOALS ➢ Garfield County will encourage a land use pattern that recognizes the environmental sensitivity of the land, does not overburden the physical capacity of the land and is in the best interests of the health, safety and welfare of Garfield County. ➢ Enhancement of the river corridor. ➢ Protection of watersheds and floodplain. ➢ Control of drainage that impacts the communities. OBJECTIVES 8.1 The County of Garfield reserves the right to deny a project based on severe environmental constraints that endanger public health, safety or welfare. 8.2 Proposed projects will be required to recognize the physical features of the land and design projects in a manner that is compatible with the physical environment. 8.3 Garfield County will ensure that natural drainages are protected from alteration. 8.4 River -fronts and riparian areas are fragile components of the ecosystem and these areas require careful review in the planning process. 8.5 Development proposals will be required to address soil constraints unique to the proposed site. 8.6 Garfield County will ensure that natural, scenic and ecological resources and critical wildlife habitats are protected. 20 8.7 Development will be encouraged in areas with the least environmental constraints. POLICIES 8.1 Garfield County shall discourage and reserve the right to deny development in areas identified as having severe environmental constraints such as active landslides, debris flows, unstable slopes, bedrock slides, major mudflows, radioactive tailings, slopes over 25 percent, riparian areas and wetlands and projects proposed within the 100 year floodplain. 8.2 Garfield County shall discourage development proposals that require excessive vegetation removal, cut and fill areas or other physical modifications that will result in visual degradation or public safety concerns. 8.3 Natural drainage patterns will be preserved so the cumulative impact of public and private land use activities will not cause storm drainage and floodwater patterns to exceed the capacity of natural or constructed drainageways, or to subject other areas to an increased potential for damage due to flooding, erosion or sedimentation or result in pollution to streams, rivers or other natural bodies of water. 8.5 The County will discourage development in areas where severe soil constraints cannot be adequately mitigated. 8.7 Garfield County will require development on lands having moderate or minor environmental constraints to mitigate physical problems such as minor rockfalls, 17 to 24 percent slopes, minor mudflows, potential subsidence, high water tables, slow percolation, radioactive soils and/or corrosive and expansive soils. Staff Response The wetlands hydrology connects to both the perennially flowing streams of Blue Creek and the Roaring Fork River. Having reviewed the TCI Lane Ranch proposal; provided following comments are related to wetlands constraints: A. Blue Creek Ditch is a permanent stream and conveys water east to west through the property. This watercourse provides significant surface and potential subsurface waters to the property. B. Three main ditches provide water to the property; the northern ditch, Blue Creek and its laterals and the lower ditch. 21 Jurisdictional Wetlands have been identified and a Jurisdictional Wetland Delineation has been finally determined by the USACE. Activity within the wetland area will be for 1) the construction of ponds for potential wetlands mitigation via stormwater management and 2) visual aesthetics. A wetlands delineation has been performed on the site using the technical guidelines set forth by the US Army Corps of Engineers. The Corps of Engineers regulates dredging or filling activities within the waters of the United States. Colorado Division of Water Resources reviewed the proposal and provided the following comments related to the wetlands: a. The submittal indicates that existing ditch water rights will be used on historically irrigated lands, as well as for individual lots in the subdivided neighborhoods and for water features and wetlands creation. The use of the irrigation water rights must not result in the expansion of its use. A change in water rights application may be necessary to allow for the irrigation of lands that were not historically irrigated, including the wetlands and as well as for use in water features, such as the proposed naturalistic stream course for Blue Creek Ditch. b. The submittal also indicates that up to one acre of wetlands may be created to compensate for the disturbance of 0.5 acres of existing wetlands. The creation of wetlands will cause depletions in the stream system through evaporation from the surface water system and the consumptive use of water by plant life. The Roaring Fork River is an over appropriated stream system. Therefore, to prevent injury to the vested water rights, wetlands mitigation must be limited to a one to one ratio. If mitigation exceeds this ratio, the stream systems must be compensated for these depletions in time, place and the amount through a court approved augmentation plan or a State Engineer approved substitute supply plan. The creation of wetlands may also expose groundwater, which by State of Colorado Statute is considered a well and must be permitted by the Division of Water Resources prior to construction. c. Records also indicate that several exempt wells may exist within the proposed development. CRS requires that the cumulative effect of all wells in a subdivision be considered when evaluating material injury to the decree of water rights. Therefore, the existing exempt wells must be included in an augmentation plan or must be plugged and abandoned Garfield County Vegetation reviewed the proposal and provided the following comments related to wetlands constraints: A. The site has been delineated; however it has been done in June 2008, during a period when the irrigation water was on going. The delineation needs to be finished when the irrigation waters are turned off. A complete delineation will provide critical information to determine if an Army Corps of Engineer 404 permit is needed for 22 accuracy. If it is determined that activities (residences, building envelopes, trails, roads, bridges) will take place in the Waters of the United States, then the Federal government will become involved and there may be issues related to the Endangered Species Act and the National Historic Preservation Act, Section 106. B. Ute's Ladies Tresses (Spiranthes diluvialis) orchid is a federally listed threatened wetland plant species. The Applicant has mapped the distribution of the plant's habitat and Staff encourages TCI Lane to continue their orchid monitoring program and to adopt an appropriate plan that will maintain the open wetland areas. Rocky Mountain Ecological Services has proposed three options to maintain the Spiranthes habitat; prescribed fire, grazing, and mowing. As the project reaches build out, mowing may be the only viable option. Staff has concerns about potential conflicts with Ute's Ladies Tresses habitat: 1. Four lots south of Mayfly Bend (66, 67, 68, 69))- 2. 9);2. Portions of Riverstone Drive and how will Riverstone Drive cross the wetland without altering the water flow and the hydrology? 3. Two lots on the north end of Dragonfly Spur (lots 56 and 57). 4. What are the future plans to channelize Blue Creek and if channelization occurs, will the area would become less saturated and spiranthes habitat would become diminished. Colorado Division of Wildlife reviewed the proposal and provided the following comments related to wetlands constraints: • Building envelopes for lots 60 through 64 should be pulled as far north as possible to eliminate any removal of riparian vegetation. Maximize building in the pasture areas that have previously been disturbed. Town of Carbondale Planning Department reviewed the proposal and provided the following comments related to wetlands constraints: • Ute Ladies' -tresses, an orchid which is listed on the Endangered Species list, is found on the property. The TCI Lane Ranch Wildlife and Vegetation Assessment Report sets out a number of recommended management practices to control weeds, as well as suggested management practices to assure that the orchid population remains stable on the property. The Planning Commission would like to recommend that these management practices be incorporated in the Declarations, as well as in the Planned Unit Development Plan. 23 Staff's original review states that based on these comments from both the Applicant's wetlands reports and the review provided by Colorado Division of Water Resources, Garfield County Vegetation, Colorado Division of Wildlife and the Town of Carbondale Planning Department, Staff and the Army Corp of Engineers finds the wetlands are a major issue and feels these concerns can be addressed through proper redesign or realignment. There is definitely the need to resolve these issues on building envelope adjustments and a defined wetlands delineation of the site before an approval can be granted. The revised application contains a new letter from the USACE providing the final JD (identifying 9.44 acres of wetlands) and an additional wetlands / Ute Ladies tresses orchid analysis. The Applicant intends to relocate 0.268 acres (11,674 sq. ft.) to another location on the property. All of the proposed activities are covered in the context of the USACE nationwide 404 permit application. These activities, while occurring in some lots, do not occur in building envelopes. The County has previously required a 20 -foot buffer between any wetlands and site disturbance / building envelopes. Staff recommends this requirement be placed on the plat as a note and shown graphically. 100 -Year Floodplain Impacts The Property does have tributaries running through much of the Property with approximately half of the property lying within the mapped 100 -year floodplain. The floodplain "fringe" area is a fairly substantial area which tracks along the Roaring Fork River Corridor leaving approximately a third of the site affected by flood inundation. Areas within the floodway are proposed for passive recreational uses only. One structure being proposed to span over the floodway is a foot bridge connecting the TCI Lane Ranch site with the Rio Grande Trail. This will provide pedestrian and bicycle access to the Rio Grande Trail as an alternative transportation route for the general public. (The illustration below shows the areas of the floodplain.) Flood Fringe The Colorado Geologic Survey (CGS) reviewed the proposal and provided the following comments related to floodplain impacts: `�',�--'' 1. The final drainage report states wY that portions of the property are within :Fringe F=k)Od the 100 year floodplain. Several homes Fringe on the southern portion of the site are loo -Year Floodplain located within the 100 year floodplain. - These sites will be elevated to a minimum of one foot above base flood elevation. Designated finished floor elevations in this area a minimum of 1.5 feet above the 100 year base flood elevation. 24 2. Flooding is a hazard that must be addressed beyond raising building pads above the one foot base flood elevation, not only to reduce the risks associated with rising waters but also to reduce the risk of undermining due to stream channel erosion and undercutting. Slope armoring such as rip rap should be placed on the face of all constructed slopes used to raise building pads and roads above the flood zone. The need for and the feasibility of additional channel and bank stabilization, scour mitigation and energy dissipation measures should be evaluated for implementation. Eagle County Planning Department reviewed the proposal and provided the following comments related to floodplain impacts: • The most significant issue facing the project if it were proposed in Eagle County is the proposed construction within the 100 -year floodplain. While Eagle County understands this is allowable as long as development is outside the floodway in Garfield County, the project's impact upon wetlands, impact upon the riparian system and vegetation would be significantly reduced by reducing and/or reconfiguring this component of the project in `Neighborhood D.' This density could be either eliminated from the project or strategically included into other nodes of development within the project. Town of Carbondale reviewed the proposal and provided the following comments related to floodplain impacts: • The Planning Commission noted the proximity of the development to the Roaring Fork River. They suggest that there be no construction within the 100 year floodplain due to potential impacts downstream. Firefly Loop raises particular concern because of its location near the river and the floodplain. The Planning Commission asked if it would be possible to cluster the development on Firefly Loop to lessen the impacts on the river and floodplain. Staff finds that the River represents a major constraint on that portion of the Property, but finds that it does not have an impact on the remaining of the Property. Garfield County allows development within the 100 -year flood "fringe" area as long as the first finished floor is one foot above base flood elevation. Staff recommends the use of hard engineering techniques of rip rap armoring to stabilize areas where fill will occur on pad elevations and roadway systems. The revised application proposes that the building envelopes that are in the flood fringe will be raised such that the first finished floor elevation (FFFE) will be shown on each lot on the Final Plat. The Applicant intends to obtain an Administrative Floodplain Permit from Garfield County in order to achieve this. The Applicant proposes that the FFFE will be 18" (1.5 feet) above the base flood elevation which meets the requirements of the floodplain regulations. M Wildlife and Vegetation Concerns The property is dominated by two types of primary vegetation communities; irrigated pasture lands of grass in northern one half and cottonwood galleries dominate the southern half with the Ute Ladies' -tresses, a federally protected wetland orchid which is found in the wetlands section of the property. The majority of the cottonwood gallery lies adjacent to the Roaring Fork River with the intermixing of spruce, ponderosa pine and juniper. There are also mature gambel oak groves throughout the site. The property contains wild turkey, mule deer, some light elk use, the Lewis woodpecker, raccoon, skunk, fox and coyote. Colorado Division of Wildlife reviewed the proposal and provided the following comments related to wildlife and vegetation: 1. The proposed TCI Lane Ranch property located between State Highway 82 and the Roaring Fork River, east of Blue Creek Ranch. It does not lie within any mapped critical wildlife areas but is adjacent to important elk and deer winter range on the south side of the Roaring Fork River. The property is use by deer and elk and generally occurs during the winter and spring months. But there is some year round deer use on the riparian corridors along the Roaring Fork River and Blue Creek. Elk use and game damage problems have increased in the last couple of years on the property with elk being drawn to hay having been stored on the property. In addition, the property is home to many small mammals, neo - tropical song birds, raptors, wild turkeys and amphibians. 2. Fencing should be held at a minimum and any necessary fencing should be wildlife friendly. For wire fencing, 42 inches for a maximum height, 4 wires at most with a 12" kick space between the top two strands. Rail fencing should be 48 inches or less with at least 18" between two of the rails. Staff feels this needs to be written into the Covenants, Conditions and Restrictions. 3. The riparian areas along both the Roaring Fork River and Blue Creek are extremely important to wildlife. i. Elk usage of the property has increased considerably during the winter months. Deer and elk conflicts are to be expected within the development and plantings of native vegetation are encouraged to help reduce some of those conflicts. Eliminating the plantings of any berry, fruit, or nut producing plants or shrubs will help discourage elk, deer, bears and other wildlife from feeding upon the landscaping. Homeowners need to be aware that the Division of P70 Wildlife is not liable for any damage to landscaping by deer, elk, or bear. Staff feels this needs to be written into the Covenants, Conditions and Restrictions. ii. Bear/human conflicts have increased within the Roaring Fork Valley and in the vicinity of Blue Creek Ranch and Catherine Store. This has the potential to be a reoccurring problem. It is important that certain measures be taken to minimize these possible conflicts.- a. onflicts:a. Homeowners have and use an approved bear -proof container for storing all trash/garbage; b. Pets should be fed indoors, and pet food or food containers should not be left outside,- C. utside;c. BBQs should also be securely housed in the garage or cleaned with a bleach solution when not in use due to the fact that leftover food and grease are an overwhelming bear attractant; d. Round door knobs on the outside of doors rather than lever - type can limit bear access into houses. Staff feels these provisions need to be written into the Covenants, Conditions and Restrictions. Town of Carbondale reviewed the proposal and provided the following comments related to wildlife and vegetation: • There are a number of recommendations in the Wildlife and Vegetation Assessment Report that are intended to protect the wildlife that currently exists on the property. Some of the impact mitigation recommendations include discouraging fencing, which is not designed to allow wildlife passage, limiting the number of domestic animals and the planting of vegetation along roadways to avoid spotlighting of foraging game at night. The City of Carbondale would strongly suggest that all of the recommendations in the report be accepted and incorporated into the subdivision documents. While these recommendations should be included in the Declaration documents, they should also be incorporated into the Planned Unit Development so they cannot be changed by a vote of an association of property owners. Bureau of Land Management reviewed the proposal and provided the following comments related to wildlife and vegetation: • BLM indicated that the builder's of the TCI Lane Ranch development will be placing a fence, so that the adjacent BLM parcel will not have access. BLM's concern centers upon there being some sensitive plants within that particular parcel. They would like the fence to be built without public access with a "no walk through gate" to the river, or to build a fence that cannot be climbed over. Staff feels this needs to be a conditional of approval. 27 V. PLANNED UNIT DEVELOPMENT (PUD) REVIEW The TCI Lane Sketch Plan was reviewed by the Garfield County Planning Commission on July 11, 2007. It was received with mostly favorable comments and recommendations. The design team initially took the concerns of the public and the recommendations of the Garfield County Planning Commission. One of the major revisions involved removing the controversial commercial tree nursery from the plan and adding another ingress/egress roadway with a small neighborhood within this area. The Owners propose to rezone the Property from A/R/RD to PUD in order to have the design flexibility required for the project. The zoning code defines the purpose of a PUD as: To permit greater design flexibility and consequently, more creative and imaginative design for development than generally possible under conventional zoning and the preliminary plan subdivision regulations. It is intended that PUDs shall be planned to insure general conformity, both in substance and location, with the goals and objectives of the master/comprehensive plan through integrated development. 4.04 CONSISTENCY WITH THE MASTER/COMPREHENSIVE PLAN No PUD shall be approved unless it is found by the County Commissioners to be in general conformity with the County's Master/Comprehensive plan(s). When appropriate, an application for an amendment to the Garfield County Master/Comprehensive Plan may be made as part of a PUD application. Any application for Master/Comprehensive Plan amendment must be approved by the Planning Commission, prior to its recommendation on the PUD application, and may occur at the same meeting. Applications for Comprehensive Plan amendment shall include justification for the amendment based upon criteria for establishing land use designations contained in the Master/Comprehensive Plan. Staff Response As discussed above, TCI Lane Ranch was granted a Comprehensive Plan Amendment on July 11, 2007, by the Garfield County Planning Commission, which provided a designation of Residential High Density. Based upon further revisions made by the Applicant, Staff finds the proposed PUD is in general conformity with the Proposed land Use Districts Map of High -Density Residential as well as with the Goals, Objectives, and Policies of the County's Comprehensive Plan of 2000, as amended. 28 4.05.02 It is recognized that the uniqueness of each proposal for a PUD and TPUD requires that the specifications, standards and requirements for various facilities, including but not limited to, affordable housing, streets, highways, alleys, utilities, curbs, gutters, sidewalks, street lights, parks, play -grounds, school grounds, storm drainage, water supply and distribution, and sewage collection and treatment, may be subject to modification from the specifications, standards, and requirements established in the Subdivision Regulations of Garfield County for like uses in other zone districts. The County Commissioners may, at the time of zoning as a PUD and TPUD, waive or modify the specifications, standards and requirements which would be otherwise applicable, as requested by the applicant. Any waiver or modification of specifications, standards and requirements will only be approved if it can be demonstrated that the proposed waiver(s) is consistent with "best engineering practices," as recommended by an engineer retained by the County. Staff Response The only requested waivers being requested from the underlying zone district (ARRD) include.- 1) nclude:1) Reduction in minimum lot size per the site plan,- 2) lan;2) Allow duplex as a use -by -right instead of a conditional use; 3) List pipelines under conditional use permit subject to pipeline regulations rather than list under use -by -right; 4) Reduction in the ROW width on the main entrance roads (Haystack Road and Riverstone Drive) from 60 feet to 50 feet; 5) Allowing "community building" as accessory use to the residential development; 6) Allowing Dragonfly Spur to exceed the 600 linear feet maximum for cul-de-sac by 200 feet; and 7) A reduction in the off-street parking for the community building from 1 space per 200 sq. ft. to 1 space per 500 sq. ft. 4.06 INTERNAL COMPATIBILITY OF PLANNED UNIT DEVELOPMENTS It is recognized that certain individual land uses, regardless of their adherence to all the design elements provided for in this section, might not exist compatibly with one another. Therefore, a proposed PUD or TPUD shall be considered from the point of view of the relationship and compatibility of the individual elements of the Plan, and no PUD or TPUD shall be approved which contains incompatible elements internally or with neighboring property. Staff Response Rej Staff recognizes the nature of the design contains housing, passive recreation, open space and a photovoltaic solar farm in a compatible layout. The project takes into account the adjacent land uses with respect to existing development patterns and land uses and is compatible with the surrounding properties in size and character. 4.07.02 The number of off-street parking spaces for each use in each PUD shall not be less than the requirements for like uses in other zoning districts, except that the County Commissioners may increase or decrease the required number of off- street parking spaces in consideration of the following factors: (1) Estimated number of cars owned by occupants of dwellings in the PUD; (2) Parking needs of non -dwelling uses; (3) Varying time periods of use whenever joint use of common parking areas is proposed. Staff Response Staff finds the development meets the parking requirements by providing all residential spaces within driveways or garages, which will be up to 506 spaces, depending on the dwelling size and number of bedrooms. No on street parking will be allowed. The community center will provide fifteen (15) spaces (including one handicapped space) and eight (8) spaces for public river access parking. Unless modified by the BOCC, the off-street parking requirement for a "public facility" is 1 space per 200 sq. ft. and the application proposes 1 space per 500 sq. ft. A reduction could be warranted as many of the residents could walk or ride bikes to this facility. However, if the facility is used for other uses beyond the community, it may end up being under -parked. 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. Staff Response Staff finds the development of a residential community of 89 new dwellings units is compatible with the surrounding land areas. The TCI Lane Ranch development averages 1.2 acres per unit with a layout design that would be congruent with the abutting properties. Aspen Equestrian Estates has one dwelling unit per 1.2 acres and the adjacent Blue Creek Ranch PUD has one dwelling unit per 1.6 acres. The PUD is designed to consider the adjacent land uses through a design that 30 complements existing development patterns and land uses. The development abuts Blue Creek Ranch PUD in which the home sites have been developed congruent in an existing pattern of design. Open space areas associated with the two developments create a similar visual buffer for travelers along State Highway 82. On the east side of the project site, development patterns are complementary with open space areas adjacent to the Waldorf School site. On the south side of the project area, the conservation easement joins public lands and the recreational Rio Grande Trail. The application indicates that the residential aspect of the development will compliment the open space uses of the site. Staff finds that due to about 23% of the site designated as residential development with over 75% being held as open space, it appears that the passive recreational uses would complement the residential development intent. Staff also finds the sole purpose of attempting to redesignate the property from Residential High Density to Planned Unit Development is to create a residential sustainable development with open areas held in perpetuity. The proposed level of residential density of 1.2 dwelling units per acre with the dedication of open space over 75% to passive recreational and visually aesthetic uses is the primary development component and is compatible with the surrounding density allowed for PUD designation. 2) The PUD shall provide an adequate internal street circulation system designed for the type of traffic generated, safety, separation from living areas, convenience and access. Private internal streets may be permitted, provided that adequate access for police and fire protection is maintained. Bicycle traffic shall be provided for when the site is used for residential purposes. Staff Response The revised application provides an internal street design that meets the County's requirements with a few exceptions noted below. The streets are to be dedicated to the public but owned and maintained by the HOA. The site plan shows a variety of walking trails through the development providing public access to the Roaring Fork River as a fisherman's Access and associated parking (8 spaces) for that use. Proposed trails within the site will interconnect with Blue Creek Ranch trail and go to the RFTA "park and ride' facility. Also, a pedestrian bridge is proposed to connect with the Rio Grande Trail, which will facilitate bicycle traffic to the Town of Carbondale. The proposed trail to the RFTA "Park and Ride" appears to cut across the open space of adjoining Blue Creek Ranch. This would need an easement to exist. The cul-de-sac that serves Lots 56 — 59 on Dragonfly Spur exceeds the 600 -linear foot maximum by 200 feet. The BOCC will need to grant this variance. The fire district did find that the road design is adequate for their needs, the development is served by a central fire protection water system with hydrants, and is located in a low wildfire danger area. Staff finds this could be waived. 31 The application proposes to reduce the ROW width on the main entrance roads (Haystack Road and Riverstone Drive) from 60 feet to 50 feet. These road sections will most likely carry a split capacity of trips from the development so this reduction in the ROW is understandable and logical. 3) The PUD shall provide parking areas adequate in terms of location, area, circulation, safety, convenience, separation and screening. Staff Finding A public parking area is provided to facilitate the Fisherman's Access to the Roaring Fork River. The central open space area will include parking for the Community Center, the park and the community garden. The application requests a waiver to reduce the requirement from 1 space per 500 sq. ft. to 1 space per 200 sq. ft. As mentioned above, a reduction could be warranted as many of the residents could walk or ride bikes to this facility. However, if the facility is used for other uses beyond the community, it may end up being under -parked. In all cases, the spaces are adequately buffered from other uses. This standard has been met. 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. Staff Finding This standard has been met holding over 75% of the site as open space. The breakdown of the open space is as follows: the Community Utility Zone District Zone of two (2) lift stations and the solar farm tabulates to 0.98 acres; the Community Center accounts for 3.09 acres; the Private Common Open Space is 33.30 and the Conservation Easement totals 32.40 acres. This standard has been met. 5) The PUD shall provide for variety in housing types and densities, other facilities and Common Open Space. Staff Finding This standard has been met with lots ranging from '/4 to '/2 acres in neighborhoods designed for both duplexes and single-family units that are both free-market and affordable housing units. The development is divided into six (6) distinct neighborhoods, which incorporates a mixed residential community including 89 residential units of duplexes and single-family detached units. These housing units range from 1,900 square foot attached duplex homes to 5,500 square foot single family homes. This standard has been met. 6) The PUD shall provide adequate privacy between dwelling units. Staff Finding 32 This standard has been met with all building envelopes setback a minimum of 15' from the lot lines, which creates a minimum of 30' from adjacent buildings. The clustering effect breaks up the units for more privacy. This standard has been met. 7) The PUD shall provide pedestrian ways adequate in terms of safety, separation, convenience, and access to points of destination and attractiveness. Staff Finding The application proposes a network of trails through the property that extend to the project's open spaces, the Roaring Fork River, the Rio Grand Trail, the Waldorf School and RFTA Park and Ride; however, there is no trail / sidewalk along the road network so the pedestrian will be required to walk in the road to get to those trails. This standard has been met through an extensive trail network through wetland areas and connecting the neighborhoods with to the open spaces and river system. This standard has been met in part but should be revised to have a roadside soft trail to provide access to the other trails rather than have pedestrians use the roadway. 8) If centralized water and/or wastewater facilities are proposed within the PUD, they shall be provided for in a separate utility zone district that shall contain its own performance standards. No land within any utility zone district shall apply toward any category of open space calculation or requirement. The PUD shall demonstrate how common water and wastewater facilities will be controlled or governed by the future owners within the PUD. Staff Findinq The applicant has dedicated Community Utility Zone District Zone of two (2) lift stations of 0.02 acres and the solar farm of 0.94 acres. There no centralized water or wastewater facilities are proposed within the PUD. This standard has been met. 9) Any disturbance of slopes in excess of 40%, shall be the minimum necessary to meet the development needs, with a revegetation and geotechnical plan submitted with the PUD application. Staff Finding This standard is not applicable because the property does not contain any slopes that exceed 40%. 10)lf community facilities are proposed to be contained or allowed in the PUD, the application shall discuss who or what entity shall be responsible for the provision of and payment for the proposed facilities. The facilities shall also be included within the overall common 33 infrastructure requirements of the PUD, to include water, wastewater and parking requirements. Staff Finding The PUD has two proposed community facilities. One is a community center with a park and an active solar farm array. The ownership and management of these facilities will be conveyed to the homeowners association as proposed in the declaration of Covenants, Conditions and Restrictions (CCR). 4.07.04 The maximum height of buildings may be increased above the maximum permitted for like buildings in other zone districts in relation to the following characteristics of the proposed building: 1) It's geographical location; 2) The probable effect on surrounding slopes and mountainous terrain; 3) Unreasonable adverse visual effect on adjacent sites or other areas in the immediate vicinity, 4) Potential problems for adjacent sites caused by shadows, loss of air circulation or loss of view; 5) Influence on the general vicinity, with regard to extreme contrast, vistas and open space; and 6) Uses within the proposed building. Staff Response The PUD is not seeking an increase to the maximum allowable building height of any of the dwelling units. 4.07.05 The maximum lot areas and the minimum setback restrictions may be decreased below and the maximum lot coverage may be increased above those applicable to like buildings in other zone districts to accommodate specific building types with unusual orientation on the lot or relationship between buildings. The averaging of lot areas shall be permitted to provide flexibility in design and to relate lot size to topography, but each lot shall contain an acceptable building site. The clustering of development with useable common open areas shall be permitted to encourage provision for, and access to, common open areas and to save street and utility construction and maintenance costs. Such clustering is also intended to accommodate contemporary building types which are not spaced individually on their own lots but share common side walls, combined service facilities or similar architectural innovations, whether or not providing for separate ownership of land and buildings. Architectural style of buildings shall not be a basis for denying approval of a PUD application. Staff Response 34 The PUD is not seeking an exception to the maximum lot areas or minimum setback restrictions. 4.07.06 The overall residential density shall be no greater than two (2) dwelling units per gross acre within the PUD; provided, however, that the County Commissioners may allow an increase to a maximum of fifteen (15) dwelling units per gross acre in areas where public water and sewer systems, owned and operated by a municipal government or special district (as defined by Section 32-1-103(20), C.R.S.) are readily available and the prior zoning classification allowed residential densities greater than two (2) dwelling units per gross acre, such increased densities shall nevertheless comply with the maximum lot coverage, minimum setback, maximum floor area ratio, maximum building height and parking standards of such prior zoning classification. The overall average residential density shall be calculated by summing the number of residential dwelling units planned within the boundary of the PUD and dividing by the total gross area expressed in acres within the boundary of the PUD. The density of dwelling units in any particular area may be greater than the maximum permitted for a like use in other zone districts. Averaging and transferring of densities within the PUD shall be allowed upon a showing of conformance with the purposes of this section through appropriate design features within the PUD that will achieve high standards of design and livability. Staff Response The PUD proposes 89 units on 100.52 acres, which calculates a mean gross density of 1.13 dwelling units per acre. This standard has been met. 4.07.07 The minimum number of acres that may comprise a PUD is two (2) acres. Staff Response The Property contains 100.52 acres. This standard has been met. 4.07.08 All uses, which are permitted in the underlying zone district or consistent with the land use designations in the Comprehensive Plan, or approved as an amendment to the Comprehensive Plan, may be permitted in PUDs. The uses, which shall be permitted in any particular PUD shall be those permitted by the resolution zoning the particular area PUD. Staff Response 35 All of the uses in the project are uses listed in the ARRD zone district. The proposed PUD Guide proposes a Two -Family Dwelling (duplex) as a Special Use which would require further review after this project is approved. Staff suggests this use be included as a use -by -right to match what is shown on the site plan. 4.07.09 Twenty-five percent (25%) of the total area within the boundary of any PUD shall be devoted to Common Open Space. Not more than twenty-five percent (25%) of the Common Open Space shall be an area of water classified as commercial open space. Of he 25% open space requirement within PUDs, no more than 40% of the 25% total required, shall be limited use open space, with the balance being retained as one or more of the remaining open space categories, listed above. Provided, however, that the County Commissioners may reduce such requirement if they find that such decrease is warranted by the design of, and the amenities and features incorporated into the Plan, and that the needs of the occupants of the PUD for Common Open Space can be met in the proposed PUD. Staff Response The PUD proposes over 75% of the project to be devoted to open space. The County would require 25 acres of open space. The proposed PUD exceeds and satisfies this requirement by providing a Community Utility Zone District Zone of two (2) lift stations and the solar farm of 0.98 acres, a Community Center of 3.09 acres, Private Common Open Space of 33.30 and the Conservation Easement totals 32.40 acres. This standard has been met. 4.07.10 If any zone district within the PUD is proposed to contain time-share or fractional ownership units, or other similar interest in property, the provisions for such ownership shall be those that are approved by the Board of County Commissioners at the time the property is zoned PUD. Staff Finding This standard is not applicable because the property is not proposing to contain time share or fractional ownership units. 4.07.11 Findings of the Planned Unit Development Regulations Section: It is essential and necessary for the preservation and for the maintenance of the health, welfare, safety, and quality of life in Garfield County to ensure the provision of affordable housing, which mitigates the impact of new development. Recognizing that new development generates additional employment needs, and being consistent with a desire to have new development mitigate impacts attributable to such development, the County finds it necessary to require new development to 36 provide affordable housing. Housing must be affordable to the local labor force in order for the local economy to remain stable and to grow in a healthy manner. 4.07.12 Purpose The purpose of this Section is to implement through regulation the Housing Goals, Objectives, Policies, and Programs of the Garfield County Comprehensive Plan for Study Area One including the following statement: "To provide all types of housing that ensures current and future residents equitable housing opportunities which are designed to provide safe, efficient residential structures that are compatible with and that protect the natural environment". The Garfield County land use review process will consider the housing needs of all economic segments of the community, and will assure that the impacts of new development will be mitigated, to the extent feasible, to assure an adequate affordable housing supply in the County. While the County recognizes that affordable housing is most desirable in or adjacent to towns, new developments throughout the unincorporated county are creating demands for workers in construction, maintenance, services, and retail sales. 4.07.13 General This Section applies to all Planned Unit Development applications, which include residential development in the Garfield County Comprehensive Plan's Study Area, 1. 4.07.15 Requirements In order to fulfill the goals of the Comprehensive Plan while directing growth into the areas designated in that plan, requirements will be based on the Proposed Land Use Districts from the Comprehensive Plan. Staff Response The PUD is overlain by one Land Use District from the Comprehensive Plan: "Residential High Density." The requirements for the PUD apply to this designation. 4.07.15.01 For Lands Designated High Density Residential (1) Planned Unit Developments - All Planned Unit Development proposals, and Planned Unit Development Amendment requests which results in an increase in density, must provide that at least 10% of the housing mix are affordable housing units. Providing 10% affordable housing units will not, by itself, be sufficient to fulfill the PUD requirement for a mix of housing. Staff Response The revised application provides that 10% (9 units) will be deed -restricted affordable housing units governed by the Garfield County Housing Authority. This proposal meets the County's affordable housing requirements for unit and bedroom count and that the 37 concerns of the Garfield County Housing Authority can be met. Staff discussed this revision with the GCHA and they support this new approach. The Code allows for a "security" provision to ensure the units are built while the free-market units are being built. This could be in the form of a cash security (letter of credit) or a provision to withhold issuance of building permits on free-market units until a building permit has been issued for a deed -restricted unit generally at a ratio of 10 free-market to one (1) deed restricted unit. In this case, the application proposes these 9 units will be constructed at a rate which will be a minimum of 10% affordable to 90% market rate at any one time. Staff suggests using the 1 to 10 ratio language for ease of administration as follows: "In order to ensure the orderly and timely construction of the 9 required deed -restricted affordable housing units, no more than 10 free market unit building permits shall be issued by the Garfield County Building and Planning Department at any one time unless a building permit has been issued for a deed -restricted affordable housing unit such that a ratio of free- market to affordable housing units shall be constantly maintained of 10 free- market to one (1) deed restricted unit." 4.08.02 An applicant may process their application for PUD zoning under this Zoning Resolution separate from and in advance of their application or applications for subdivision platting under the Garfield County Subdivision Regulations. Staff Response The application is for both PUD and Preliminary Plan. The applicant requests that these two items be reviewed and processed simultaneously. 4.08.03 The plan shall show where within the PUD each type of use will be located and shall indicate the total acreage which will be devoted to each use, where no subdivision of the property is proposed as a part of the PUD. The precise location of each use and the location of lots, blocks or other parcels within each area devoted to each use shall be shown as that area is subdivided and platted in accordance with the Garfield County Subdivision Regulations. Staff Response The application does provide the acreage devoted to each open space area and areas to be developed for residential use. The proposed PUD Preliminary Plat includes the required information. This standard has been met. 4.08.04 The uses by right, conditional uses, minimum lot area, maximum lot coverage, minimum setbacks, maximum height of buildings, and all other use and W. occupancy restrictions applicable to any area zoned as PUD shall be those which are approved by the County Commissioners at the time such area is so zoned. Staff Response All of the areas within the proposed PUD are designated as zone districts within the PUD Guide, which details the above requirements and specific land uses. 4.08.05 The applicant shall include with the written request for PUD zoning which does not include a subdivision Preliminary Plan application the following information: (1) A statement of the ownership interest in the property to be included in the PUD and the written consent of all of the owners; (2) A PUD Plan indicating the broad concept of the proposed development. Such Plan shall clearly indicate: a. The maximum number of dwelling units proposed within the overall area; b. The minimum acreage that will be dedicated to Common Open Space; c. The type of uses proposed and the acreage devoted to each use; d. Major internal circulation systems; e. The acreage, which will be dedicated for school, sites; f. The general nature and location of commercial and industrial uses, if any, to be located in the PUD; g. Provision for water, sewer, telephone, electricity, gas and cable television, if applicable; and h. Other restrictions proposed by the applicant such as building setbacks, height limits, access requirements and grade or slope restrictions to be applied to particular areas, written in the form of a zone district text the same as, or in similar form to, the Garfield County Zoning Resolution; and Staff Response Sections 1, 2 (a) - (h) required above, have been submitted in the Binder. 39 i. If more than one phase is proposed, a phasing plan shall be included in the application that delineates the proposed phasing of the development. Staff Response The application does not contain a phasing plan: (3) A regional location map showing the relationship of the site to connecting roadways, public facilities, commercial and cultural facilities and surrounding land uses; Staff Response This has been met. (4) A site map illustrating site boundaries, acreage, existing structures and the existing zoning; Staff Response This has been met. (5) A site topographic map showing at least five-foot contour intervals, major vegetation elements, streams, rivers, ditches and areas subject to 100 Year flooding; Staff Response This has been met. (6) A legal description of the area that the applicant wishes to include in the PUD; Staff Response This has been met. (7) A written statement containing the following information: a. An explanation of the objectives to be achieved by the PUD; b. A development schedule indicating the approximate dates when construction of the various stages of the PUD can be expected to begin and be completed; Staff Response As mentioned above, the plan does include completion dates by 2015. c. Copies of any special covenants, conditions and restrictions, which will govern the use or occupancy of the PUD; provided, however, 40 that the applicant may impose additional covenants, conditions and restrictions on any particular area in connection with the platting of such area; Staff Response The application contains protective covenants. This standard has been met. d. A list of the owners of properties located within two hundred (200) feet of the boundaries of the PUD and their addresses; Staff Response This has been met. e. A statement by a licensed engineer, with supporting calculations and documentation, which shall provide evidence of the following: i. The proposed water source legally & physically adequate to service the PUD; Staff Response The application proposes to provide drinking, fire suppression, and irrigation water. Potable water will be conveyed to the development by water services provided by Mid Valley Metropolitan District. The improvement plans for the project were sealed and signed by Curtis Charles Stevens, a licensed engineer in the State of Colorado. The application was referred to the Colorado Division of Water Resources which ultimately found that "the proposed water supply is physically adequate and will not cause material injury to existing water rights so long as the District operates according to the terms and conditions of its current plan for augmentation. The use of irrigation water must not result in an expansion of use and approval of a change of water right by the water court may be necessary if the place or type of use is changed." Our current Zoning Resolution, 4.08.05(7)(e)(i) requires that a PUD application include evidence from a licensed engineer that the proposed water source is legally and physically adequate to serve the PUD. Recent revisions to the state Local Government Land Use Control Enabling Act via HB 08-1141, specifically C.R.S. 29-20-303(1) now mandates that a local government shall not approve an application for a development permit unless, "after considering the application and all of the information provided, that the applicant has satisfactorily demonstrated that the proposed water supply will be adequate." State law also requires that this determination as to adequacy occur "only once during the development permit approval process unless the water demands or supply ...are materially changed. Local governments have the discretion to determine the stage in the development permit approval process at which such determination is made, "C. R.S. 29-20-302(1). 41 This section also provides, in (2), that "Nothing in this part 3 shall be construed to require that the applicant own or have acquired the proposed water supply or constructed the related infrastructure at the time of the application." Staff believes that this limitation is consistent with the prior County interpretation of the Zoning Resolution provision above, i.e. that the proposed water supply will be adequate once acquired and constructed as represented in the application. "Adequate" is defined in 29-20-302(1) to mean "a water supply that will be sufficient for build -out of the proposed development in terms of quality, quantity, dependability, and availability to provide a supply of water for the type of development proposed...." "Development permit" is defined in C.R.S. 29-20-103(1) as "any preliminary or final approval of an application for rezoning, planned unit development, conditional or special use permit, subdivision, development or site plan, or similar application for new construction..." Although the County has not implemented any regulations under this new law, staff has recommended that the determination of adequacy for a PUD rezoning occur at the time of PUD approval. Because the PUD regulations in our zoning code require only one decision by the County Commissioners for an approval, the "one time" determination of adequacy must be made by the Commissioners at the time of the PUD hearing. The Planning Commission can make recommendations about this determination. State law also requires the information to be considered by the local government in its determination of adequacy of the water supply, C.R.S. 29-20-305(1), as follows: (a) The documentation required to be submitted by the applicant, as itemized in C.R.S. 29-20-304, including the estimated water supply requirements of the proposed development through buildout; a description of the physical source of water supply; an estimate of the amount or water yield projected from the proposed water supply under various hydrologic conditions; water conservation measures, if any; water demand management measures, if any; and such other information as may be required by the local government. (b) If requested by the local government, a letter from the state engineer commenting on the documentation listed in (a), (c) Whether the applicant has paid to a water supply entity a fee or charge for the purpose of acquiring water for or expanding or constructing the infrastructure to serve the proposed development; and (d) Any other information deemed relevant by the local government to determine, in its sole discretion, whether the water supply for the proposed development is adequate, including, without limitation, any information required to be 42 submitted by the applicant pursuant to applicable local government land use regulations or state statutes. The application proposes to connect with MVMD for both water and sewer services. The application proposes that potable water will be conveyed by way of off site connections at the Cerise Ranch lift station. As mentioned earlier, the County's Comprehensive Plan strongly discourages private water / wastewater systems as a way to encourage large / high density projects and to locate in areas where existing (municipal) systems already exist that are more suited to administer such systems in the event of organizational failures exist. Mid Valley Metropolitan District issued a commitment letter to serve the site on February 14, 2007. In the letter, the District disclosed that they had the capacity to serve ninety (90) units within the development for both water and sewer. Additionally, SGM (engineer for the District) provided a letter stating the District has the ability to physically serve the development. Staff finds the information submitted by the District's attorney and engineer and the State Division of Water Resources demonstrates that this development can meet the terms of HB -1141, the County's Zoning Resolution of 1978, as amended, Subdivision Regulations of 1984, as amended and is physically and legally adequate to serve the development. ii. The proposed method in which storm drainage will be handled, demonstrating that adjoining property owners would not be damaged by the development; and Staff Response The Property contains a variety of surface water conveyance channels and retention drainage basins as well as subsurface cross drains under roadways that will need to be carefully reviewed due to the presence of these proposed stormwater collection systems in a variety of associated wetlands along the Blue Creek and the Roaring Fork River. The application contains a final drainage report prepared by Drexel, Barrell and Company. Garfield County Staff reviewed the report and provided the following comments: • Watershed. The Historic Basin has been divided into six (6) existing sub -basins based on contour mapping, survey information and field investigations. This will generate runoff in addition to the volume calculated within the development on a pre- post calculation methodology using the rational method derived from the SWMM program of intensity, duration and frequency. • Treatment of Stormwater Runoff. Water quality treatment for storm water is discussed within the Preliminary Plan. In order to protect the water quality in Blue Creek and the Roaring Fork River, it the county's expectation that all runoff from roadways, parking areas, roofs, and similarly developed areas will be treated using best management practices of retention basins and sedimentation swales as per the submitted improvement plans. 43 • Flood Plain. Any construction within a floodplain will require a flood plain permit from Garfield County Building and Planning Department. • Wetlands. Neighborhood "D" of Firefly Loop (Lots 60 through 64), Dragonfly Spur (Lots 56 and 57) and Mayfly Bend (Lots 66, 67, 68 and 69) indicates lot areas that could possibly containing wetlands. Building envelopes should be revised in these wetland areas after a defined area of wetlands boundaries have been determined. iii. The proposed method in which provision will be made for any potential natural hazards in the area such as avalanche areas, landslide areas, flood plain areas, and unstable soils, and the extent and mitigation of such hazard(s); Staff Response The Property contains natural hazards including floodplain areas associated with the possibility of sinkholes. The CGS provided significant comments related to the physical geography / geology of the site which have been addressed above. Ultimately, CGS resonates what the drainage report indicates as: Portions of the property are within the 100 year floodplain. Several homes on the southern portion of the site are located within the 100 existing year floodplain. These sites will be elevated to a minimum of one foot above the 100 year base flood elevation. Designated finished floor elevations in this area are a minimum of 1.5 feet above the 100 year base flood elevation. Flooding is a hazard that must be addressed beyond raising building pad elevations one foot above the 100 year base flood elevation, not due to the risks associated with rising waters but also to reduce the risk of undermining due to stream channel erosion and undercutting. Slope armoring such as rip rap installation should be placed on the face of all constructed slopes used to raise building pads and roads above the flood zone. The need and feasibility of additional channel and bank stabilization, scour mitigation and energy dissipation measures should be evaluated". Sinkholes are a potential concern on the site but are far less critical than flooding and flood related erosion hazards. Hepworth-Pawlak's recommendations are appropriate "if conditions are indicative of sinkhole related problems are encountered during site specific soil and foundation studies for the houses and other movement sensitive facilities, an alternative building site should be proposed or the feasibility of mitigation evaluated ... Prospective homeowners should be advised of the sinkhole potential, since early detection of building distress and timely remedial actions are important in reducing the cost of building repair and should an undetected subsurface void start to develop into a sinkhole after construction. MI Regarding the threat of fires on the Property, the Carbondale & Rural Fire Protection District reviewed the proposal and provided the following comments: Access The proposed access throughout the subdivision appears to be adequate for emergency apparatus. Water Supplies for Fire Protection The Mid Valley Metropolitan District has agreed to service the development. The submittal documents indicate that a 12" water main would be extended from the Cerise Ranch Subdivision to serve the TCI Lane Ranch. Within the subdivision, an 8" loop system would be installed. The drawings indicate that PVC water mains are proposed, which are unusual for developments within our area. These may or may not be acceptable to the Mid Valley Metropolitan District. Residential units are proposed up to 5,500 square feet in size which will require flows of 2000 gallons per minute (GPM). It appears that the system would be capable of providing adequate fire flows. Two thousand 2000 GPM fire flows require decreased spacing of the fire hydrants (Note: applicant has addressed the fire hydrant spacing issue with revised improvement plans). Impact Fees The development is subject to development impact fees adopted by the district. The developer will be required to enter into an agreement with the District for the payment of development impact fees. Execution of this agreement and payment of the fees are due prior to the recording of the final plat. Fees are based upon the impact fees adopted by the District at the time the agreement s executed. The current fee for residential development is $704.00 per unit. The following is a list of other items the developer will need to present to Carbondale & Rural Fire Protection District for review and approval if this application is approved and they move forward with the project, this list is not all-inclusive and other items may -be added in the future.- Utility uture: Utility plans showing the revised proposed water system and the new location of fire hydrants,- Landscape ydrants, Landscape plan in which showing that the plants and grasses uses to re - vegetate disturbed areas are as fire resistive as possible. If designers needs lists of fire resistive plants, grass and shrubs they can contact Carbondale & Rural Fire Protection District, Deputy Fire Marshal; ➢ Present the proposed road and building addressing signage designs for approval, see Section 505, Premises Identification, 2003 International Fire Code, besides the requirements in this section the signage shall be reflective. 45 General items that will be addressed in more detail if the project moves forward and building plans are submitted for review: ➢ All buildings shall have interior automatic fire suppression and fire alarm systems installed in them. The systems shall be designed and installed to the most current NFPA standard for these systems; ➢ Knox key boxes will be require on all buildings with fire protection systems installed in them, some may require Knox key switches to deactivate electrical power in them; ➢ We shall conduct or witness fire flow tests on the site water system prior to the finial approvals and sign -off on the system by Garfield County. Additionally, regarding fire hydrant locations, the County Project Engineer pointed out that "The Fire Marshall will comment on the adequacy of fire hydrants. However, 1 do not believe that the development has sufficient hydrants to meet the standard of having a hydrant within 250 feet of the lot frontage". f. Easements showing vested legal access for ingress and egress from a public road to the PUD and/or documentation demonstrating access shall be acquired across a public right-of-way or easement within two (2) years of any PUD approval and said access shall be vested prior to final platting of any property subject to the easement across the right-of-way; and Staff Response The PUD proposes to improve and utilize two access routes through the development and an emergency access route through Blue Creek Ranch PUD. This is particularly important from an emergency access perspective by providing a looped road system and an alternative emergency route for additional access. A voluntary riparian buffer corridor was utilized in the design process in order to protect water quality, wildlife habitat plus add a recreational experience for the Roaring Fork River. All areas of the property near the river will be dedicated Conservation Easement from the Roaring Fork Conservancy with no lot coverage. Lots that will be adjacent to this buffer area will have building envelopes that will limit home construction on the front end of the lot. Major vegetation species in the riparian corridor include cottonwood, willow, spruce, pinion juniper and ponderosa pine. g. 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 historical features. The applicant may submit any other information or exhibits, which she/he deems pertinent in evaluating his proposed PUD. Staff Response Staff finds the project has been designed, in large part, in consideration of the natural environment. The revised application materials address wetland, orchid, internal road circulation, off-site road impacts adequately. Regarding wildlife, the application contains a wildlife study prepared by Rocky Mountain Ecological Services, Inc. Staff also referred the application to the Colorado Division of Wildlife (DOW) which responded with comments attached hereto. The DOW believes the proposed development (additional human activity and trails reconfiguration) in the wetland area will increase wildlife encounters through human interaction and the development could create some negative impacts to wildlife. Staff suggests the PUD require all of the mitigation measures of DOW recommendations listed here: Building envelopes for lots 60-64 should be pulled as far north as possible to eliminate any removal of riparian vegetation. Maximize building in the pasture areas that have previously been disturbed. 2. The riparian areas along the Roaring Fork River and Blue Creek are extremely important to wildlife. Due to the critical nature of these areas for wildlife it is recommended that any proposed trails/paths be minimized and public access should be limited into these areas. Access should be closed completely Dec 1 - March 15 to limit disturbance to big game and wintering bald eagles utilizing the riparian corridor. 3. As noted the property in not located within any mapped big game critical habitat areas, however elk usage of the property has increased considerably during the winter months. Deer and elk conflicts are to be expected in the development and plantings of native vegetation are encouraged to help reduce some of those conflicts. Eliminating plantings of any berry, fruit, or nut producing plants or shrubs will help discourage elk, deer, bears and other wildlife from feeding on landscaping. Homeowners need to be aware that the Division of Wildlife is not liable for any damage to landscaping by deer, elk, or bear. 4. The proposed bridge over the Roaring Fork River should be gated to prohibit access to the RFTA during the winter closure period. 5. Bear/human conflicts have increased in the Roaring Fork Valley and in the vicinity of Blue Creek Ranch and Catherine Store, and have the potential to be a reoccurring problem. It is important that certain measures be taken to minimize these conflicts: a. Homeowners have and use an approved bear -proof container for storing all trash/garbage. 47 b. Pets should be fed indoors, and pet food or food containers should not be left outside; c. BBQs should also be securely housed in the garage or cleaned with a bleach solution when not in use due to the fact that leftover food and grease are an overwhelming bear attractant; d. Round door knobs on the outside of doors rather than lever -type can limit bear access into houses. 6. All utilities buried. 7. Fencing should be held to a minimum. Any necessary fencing should be wildlife friendly. For wire fencing, 42" maximum height, 4 wire with a 12" kick space between the top two strands. Rail fencing should be 48" or less with at least 18" between 2 of the rails. 8. Homeowners are responsible for removing dead wildlife which may die on their property. 9. Follow recommendations outlined in the wildlife report prepared by Eric Petterson of Rocky Mountain Ecological Services, Inc. 4.09.05 The development and construction of and within all PUDs shall be done in such manner and fashion that minimizes disturbance to adjacent land uses and owners. Access for all construction equipment shall be designated within the PUD proposal and shall bear a logical relationship to any proposed phasing of the development. Staff Response Construction of infrastructure improvements is proposed to begin in 2009. The proposed plan is to install the project's entire infrastructure (roads, utilities, drainage, etc.) in one continuous phase throughout 2009, with asphalt paving to be completed prior to the closing of local asphalt plants in the fall of 2009. Trails, landscaping, revegetation and the pedestrian bridge (if capitalized) are intended to occur during the 2010 construction season. This is not a phased project so all of the improvements (on- site and off-site) shall occur in one phase and be secured as such. Homebuilding is planned to begin in 2010 with the existing gravel access road into the property to act as the construction entrance off of State Highway 82 frontage road. This entranceway will be maintained during the preliminary vertical construction phase to accommodate construction traffic and as a materials staging area. The Applicant anticipates that approximately 15 to 25 homes will be constructed per year until complete build -out. Full build -out is expected between 2013 and 2015, which will be subject to market conditions with adjustments made accordingly. Staff finds that the frontage road will be capable of handling large slow moving construction vehicles because of minimal traffic conflict with the public and residents within the area of State Highway 82 frontage road. This will be the only way to and from the Property during a 5 year build -out phasing plan. VI. STAFF COMMENTS FOR THE PRELIMINARY PLAN The following section provides an analysis of the proposal with respect to requirements in Section 4:00 of the Subdivision Regulations of 1984, as amended. A. Water Supply and Wastewater Sewer and water service will be provided by the Mid Valley Metropolitan District (MVMD), as demonstrated by the commitment to serve letter dated February 14, 2007. The on-site sewer and water improvement plans have been submitted as part of the preliminary plan. In the letter of commitment to serve, Mid Valley Metropolitan District has agreed to annex TCI Lane Ranch into its service area and provide service to the development. This annexation does not constitute a material modification of the Districts Service Plan, as per state statute and the Board of County Commissioner's determination. MVMD has assured TCI Lane Ranch and Garfield County that it has adequate legal and physical water in place too serve the community. In compliance with the requirements of HB 1141, documentation has been provided from MVMD's legal counsel describing their legal and physical water sources, water yields, Master Plan and drought year scenario. As per the letter Leavenworth and Karp to Garfield County Building and Planning dated December 29, 2008, the easements necessary to extend potable water and wastewater service to TCI Lane Ranch are already in place. The extension of MVMD service area would begin from the Cerise Ranch development about Y2 of a mile east from TCI Lane Ranch, where existing MVMD easements allow for the connections to the north side of State Highway 82 Right of Way. From this beginning point, the service line will extend westward along the State Highway 82 Right of Way then under Highway 82 by way of a boring to reach TCI Lane Ranch. The plans and easement drawings provide details on the alignment and sizing of these off site improvements. TCI Lane Ranch will have two on-site wastewater lift -stations in two separate Utility Zone Districts. These wastewater improvements will be built by the developer and then conveyed to Mid Valley Metropolitan District for ownership, operation and management with the two Utility Zone Districts being decentralized by the developer. Mid Valley Metropolitan District will be obtaining the necessary permits and authorizations in order to extend their service infrastructure to TCI Lane Ranch. This involves obtaining a CDOT permit and producing described drawings for their planned utilization of private easements within Cerise Ranch for their water and sewer extensions. Four wells do exist on the property with underground water rights. The existing wells are located within the common open space area on the site plan. These wells will be capped with the Homeowners Association maintaining the rights to those wells. The Mid Valley Metropolitan District will also require the reservation of a new augmentation well site within TCI Lane Ranch. TCI Lane Ranch owns significant raw water rights from several ditches and these water rights will be maintained and conveyed to the_Homeowners Association. The exception will be a portion of that right will be dedicated to the proposed Conservation Easement for the use in preserving and maintaining the conservation values attached to the property. The remainder of the raw water will be utilized to provide irrigation support for common areas and residential lots within the development, including constructed wetlands. Irrigation for individual lots will be provided by a separate raw water irrigation system that is fed by a centralized "wet well" and pressurized pump station from one of the project ditches. A guideline will prescribe a maximum area for spray irrigation of each individual lot. Garfield County Project Engineer made the following comments on water supply and wastewater issues: Water Distribution Sewer A. Depiction of Internal Water Distribution Pipelines — No issues. B. Depiction of Offsite Water Pipeline to Development — Not submitted. These plans will be prepared by the Applicant's engineer and reviewed by the Mid Valley Metro District's engineer. The main issue to the County is proof that CDOT will allow the utilities in the Highway 82 ROW and whether there is adequate room in the ROW for both the water and sewer line. C. Depiction of Internal Sewers — No issues. The design of the internal pump stations needs to be reviewed by Mid Valley Metro District's engineer and State Engineer since MVMD will operate the pump stations. D. Depiction of Offsite Sewer.- Same comment as for the offsite water lines. Physical and Legal Source of Water E. Required Letter or Report: Per the County Code, the application needs to include one of the following: (i) a letter from a professional engineer with the information listed in the County Code, or (ii) A reviewed and updated 50 Water Supply Plan that is on file with the local government. (The submitted reports do not constitute a Water Supply Plan.) F. The Applicant shall provide a report demonstrating that the proposed offsite water and sewer lines are adequate to serve other existing or future developments. Staff finds that the off site water and sewer plans must be reviewed and approved by the Mid Valley Metro District's Engineer. The design of the internal pump stations needs to be reviewed and approved by Mid Valley Metro District's Engineer. Finally, as stated above, the application proposes to provide drinking, fire suppression, and irrigation water. Potable water will be conveyed to the development by water services provided by Mid Valley Metropolitan District. The improvement plans for the project were sealed and signed by Curtis Charles Stevens, a licensed engineer in the State of Colorado. The revised application was referred to the Colorado Division of Water Resources which ultimately found that "the proposed water supply is physically adequate and will not cause material injury to existing water rights so long as the District operates according to the terms and conditions of its current plan for augmentation. The use of irrigation water must not result in an expansion of use and approval of a change of water right by the water court may be necessary if the place or type of use is changed." Mid Valley Metropolitan District issued a commitment letter to serve the site on February 14, 2007. In the letter, the District disclosed that they had the capacity to serve ninety (90) units within the development for both water and sewer. Additionally, SGM (engineer for the District) provided a letter stating the District has the ability to physically serve the development. Staff finds the information submitted by the District's attorney and engineer and the State Division of Water Resources demonstrates that this development can meet the terms of HB -1141, the County's Zoning Resolution of 1978, as amended, Subdivision Regulations of 1984, as amended and is physically and legally adequate to serve the development. B. Internal Road /Access The development has direct access to a public road (State Highway 82 Frontage Road also known as Old 82) with two access permits presently in place with CDOT, which are to be used with the subject proposal. The permits appear to be satisfactory to the County Road and Bridge Department but only made comment regarding the emergency access onto County Road 100. The internal road systems is a looped and fork design providing two points of access into and out of the development onto State Highway 82 frontage road. All roads within the TCI Development have been designed per county design standards in Section 9:35 of the Subdivision Regulations and meet the minimum design criteria for emergency 51 vehicles per Garfield County and Carbondale & Rural Fire Protection Districts standards. The exception is a requested waiver for Haystack Drive & Riverstone drive which are reduced in width from 60 feet to 50 feet and a request for a waiver for 200 feet for a long cul-de-sac on Dragonfly Loop. The road system within the development will be un -gated and private road dedicated to the public. Lot lines within each neighborhood will extend to the centerline of the roads. The road circulation pattern has been designed to quickly disperse traffic into each of the six (6) neighborhoods, which helps to minimize traffic volumes on the roadway. Also the curvilinear design or "reverse curves" tend to slow down the speeds of vehicles on the roadway. Road construction drawings have been submitted as part of the overall application with utility easements. Garfield County Project Engineer made the following comments on roadway issues.- A. ssues: A. Layout and Grades - The proposed dead end roads exceed 600 feet in length and do not comply with the Land Use Code. (The submission is being reviewed under the old County Land Use Code that limits the length of dead end roads to 600 feet.) Section 9:33 states that cul-de-sacs and dead end streets may be designed under two circumstances: 1) cul-de-sacs may be permitted provided that they are not more than 600' in length and have a turnaround radius of not less than 45' from the center of the cul-de-sacs to radius edge and 50' of right of way for residential development and 2) dead end streets shall be discouraged except in cases where the dead end is meant to be temporary with the intent to extend or connect the right of way in the future The Board may approve longer cul-de-sacs for topographical reasons and it can be proved that fire protection and emergency egress and access is provided as a part of the longer design yet this has not been addressed. B. Road Width: The road driving surface widths, ranging from 16 foot to 24 foot, complies with the County's standards. C. Shoulder Widths: The proposed road shoulder widths do not comply with the County's road standards. When Average Daily Trips (ADT) on the roadway is more than 201 vehicles per day, four foot shoulders (minimum) are required. [The ADT is calculated as follows: Number of homes using street x 9.6 trips per house per day.] D. On -Street and Public Parking: No on -street parallel parking can be allowed since the roads have not been designed to accommodate parking. A sign is needed on the Fire Loop parking area designating that the spaces are for short term use and reserved for visitors using the trail. The revised internal road design otherwise meets the County's standards. 52 C. External Road Impacts The only road serving TCI Lane Ranch is the State Highway 82 frontage road. The intersection of State Highway 82 and County Road 100 is the primary intersection vehicles will use when accessing TCI Lane Ranch. In its present condition, the intersection of State Highway 82 and County Road 100 cannot sustain the current volume of traffic during peak hour volumes. The increased level of service which would result from the proposed TCI Lane Ranch residential development would diminish, even though an increase of only 5% volume in traffic will occur from this development. The Access Code states an access permit is needed when the traffic volume is over 20% from a given development. Upon development, TCI Lane Ranch is expected to generate a total of 784 trips during average weekday. It includes 14 inbound and 47 outbound trips during the morning peak hour and the evening peak hour would add an estimated 51 inbound and 30 outbound trips. Thus, the development will only increase the traffic volume by less than 5%. Therefore an access permit is not needed at the County Road connection for this project. CDOT does not have any process to make the developer address this need for intersection improvements. The addition of the project generated traffic should not have a potentially significant impact on the roadway facilities upon the project completion. If historical traffic growth rates persist in the vicinity of TCI Ranch, significant improvements may be required to maintain an acceptable level of service in and around the intersection of State Highway 82 and County Road 100. But these improvements are required today, even without the development of TCI Lane Ranch. The intersection at State Highway 82 and County Road 100 is not within any of the County's Traffic Impact Fee Zones. It has been recommended to Staff by referrals that the County, through the land use process, does have an ability to address this impact to the majority of the road users in the area and that the County should consider it as a condition of approval for TCI Lane Ranch. The revised application proposes to make certain specific improvements designed by Drexel, Barrell & CO that have been reviewed by CDOT which will ultimately result in a right turn lane from northbound CR 100 to the up valley direction of Stet Highway 82. Additionally, the applicant will construct a raised median between the northbound and southbound directions on CR 100 (within the SH82 ROW) adding additional safety to the turning movements. These improvements are to be paid for exclusively by the developer within the context of the Improvements Agreement and represents their fair share of needed improvements. D. Soils/Geology The preliminary geotechnical study was prepared by Hepworth-Pawlak Geotechnical. The purpose of the study was to evaluate the geologic and subsurface conditions and the potential impact it would have on the project. A field exploration study was 53 preformed consisting of a reconnaissance and exploratory pits to obtain information on the site and subsurface conditions. The site conditions of the property lies to the north of the nearly level Roaring Fork River Valley about three and a half miles east of Carbondale. The valley floor has an average slope of about 2% fall down to the west. It is made up of several river terraces that are separated by low escarpments. These escarpments are about 6 to 20 feet high and have slopes anywhere form 50% to 70%. The terraces lie anywhere from 4 to 46 feet above the Roaring Fork River. Geologic conditions that could pose a high risk were not identified by the study but there are geologic conditions of flooding and sinkholes that should be considered in the planning process. The low lying terraces along the Roaring Fork River may be subject to periodic flooding during high river flows. The Applicant intends to obtain a floodplain permit for this development through the process of finalization. The study states that sinkholes were not observed at the project site during the field study but the likelihood that a sinkhole will develop during a reasonable exposure time at the project area is low. The Colorado Geologic Survey (CGS) reviewed the proposal and provided the following comments related to floodplain impacts and sinkholes: A. The final drainage report states that portions of the property are within the 100 year floodplain. Several homes on the southern portion of the site are located within the 100 year floodplain. These sites will be elevated to a minimum of one foot above base flood elevation. Designated finished floor elevations in this area a minimum of 1.5 feet above the 100 year base flood elevation. B. Flooding is a hazard that must be addressed beyond raising building pads above the one foot base flood elevation, not only to reduce the risks associated with rising waters but also to reduce the risk of undermining due to stream channel erosion and undercutting. Slope armoring such as rip rap should be placed on the face of all constructed slopes used to raise building pads and roads above the flood zone. The need for and the feasibility of additional channel and bank stabilization, scour mitigation and energy dissipation measures should be evaluated. C. Sinkholes are a potential concern on the site but are far less critical than flooding and flood related erosion hazards. Hepworth-Pawlak's recommendations are appropriate "if conditions are indicative of sinkhole related problems are encountered during site specific soil and foundation studies for the houses and other movement sensitive facilities, an alternative building site should be proposed or the feasibility of mitigation evaluated. Prospective homeowners should be advised of the sinkhole potential, since early detection of building distress and timely remedial actions are important in reducing the cost of building repair and should an undetected subsurface void start to develop into a sinkhole 54 after construction. Staff finds slope armoring such as rip rap should be placed on the face of all constructed slopes used to raise building pads and roads above the flood fringe area. Prospective homeowners should be advised of the sinkhole potential and the Applicant take site engineering measures to inspect and indicate the possibility of sinkholes within the developed areas. E. Drainage The Application contains a Final Drainage Report prepared by Drexel, Barrell and Company which can be located under tab V of the Application. Additionally, the Drainage Plan was submitted as an Improvement Plan Sheet in the preliminary plan set which demonstrates how drainage is managed throughout the property. Ultimately, the reports states that there is no impact to downstream properties and on site detention is required on site. This analysis has been signed and stamped by an engineer licensed to practice in the State of Colorado. This standard has been met. Garfield County Project Engineer reviewed the Drainage Plan and provided the following comments: A. l don't understand the weir design for the detention ponds and how it fits with the outlet structure and the 46 box culvert. I understand that weir creates permanent amenity ponds (ponds 2 and 3). How will water remain in these ponds if they still a 2" outlet orifice below the weir elevation,- B. levation;B. A word of caution ... The Windrow Way detention basin emergency overflow for the 100 year storm is at an elevation of approximately 6296 feet. This will keep adjacent lots from flooding. However, an inadvertent increase in this overflow elevation could result in the flooding of Lot 37. Staff finds that surface drainage design of the site uses the natural drainage conveyance system to its greatest extent. Because of the topography, area of wetlands and the southern section of the site being within the 100 year floodplain, the routing of water through the site is acceptable for stormwater collection and surface conveyance. F. Fire Protection The property is located in the Carbondale & Rural Fire Protection District. The development proposes to have water service provided by the Mid Valley Metropolitan District in a centralized water supply system of hydrants. A plan view set of drawings shows the location of all fire hydrants throughout the site. The District submitted a letter dated January 30, 2009, which reflects a review of hydrant spacing within the site as being inadequate because of the 2000 GPM need for the lots on Dragonfly Loop where residential units are proposed up to 5,500 square feet in size which will require flows of 2000 gallons per minute (GPM). It appears that the system would be capable of providing adequate fire flows. Two thousand (2000) GPM fire flows require decreased 55 spacing of the fire hydrants. It appears that TCI Lane Ranch has agreed with the fire protection measures and revised all of hydrant locations and additions. G. Wildlife Regarding impacts to wildlife and the natural environment, the Applicant did submit a Wildlife and Vegetation Assessment Report prepared by Rocky Mountain Ecological Services. The Application refers to tab V. This PUD application proposes residential development which will be slightly visible from State Highway 82. The development will hold over 75% of the site as open space and should have minimal impact of displacing unpressured wildlife that presently uses the property. The Application states that deer and elk presently graze on the property which also provides a route to get to the Roaring Fork River. This has also been testified to by the Division of Wildlife. The development of TCI Ranch is designed to leave large blocks of habitat relatively in tact for deer usage. However, the indirect use of dogs and increased activity by humans would compound unavoidable losses of wildlife habitat. Deer use around home sites will likely continue but at a lower level. Staff finds that social and planned trails through the cottonwood areas should be minimized as much as possible. Staff has suggested several conditions to help mitigate impacts to wildlife. H. Vegetation Management Staff referred the revised Application to the County Vegetation Manager who provided the following comments: Ute's Ladies Tresses Assessment focused on the impacts to the wetlands and weed control. Wetland issues revolve upon a "dry period" wetlands delineation, the Ute's Ladies Tresses (Spiranthes diluvialis) orchid, which is a federally listed threatened plant species, constructed trails within the wetlands, the site design/alignment of Mayfly Bend, Riverstone Drive and Dragonfly Spur to minimize the impacts on the orchid and to disallow landowners from adding fill material into designated wetlands within their lots Noxious Weeds 1. Inventory, mapping, and management -The applicant has provided a noxious weed inventory and management plan. Staff encourages the applicant to follow the weed management plan as outlined by RMES, in particular the section, Prioritization of Weed Control on page 30 of the Wildlife and Vegetation Assessment Report. 2. In addition staff requests that weed management is written into the Subdivision Improvements Agreement to guarantee that weed management will occur in the future on undeveloped lots and for the open space areas. We recommend an amount of $6000 per year for four (4) years ($24, 000). 56 Revegetation 1. Revegetation security: The applicant has quantified the surface area to be disturbed as twenty four (24) acres. We suggest a revegetation amount of $2500 per acre for the upland areas, which would total $60, 000. 2. Constructed Wetland Security: This area is almost three (3) acres in total, we request that the applicant provide Garfield County with a cost estimate for this work. When this information is provided, staff will recommended a security amount for the wetlands work. 3. The security shall be held by Garfield County until vegetation has been successfully reestablished according to the Garfield County Weed Management Plan Reclamation Standards. 4. All mulch or erosion control bales used in the project should be specified to be either weed free straw bales or weed free hay bales. Mosquito Management • Staff requests that the applicant address the issue of mosquito management in the neighborhood constructed wetlands area. Covenants • Wetlands are mentioned in the covenants (3.36.4). 1 suggest that additional language be added that would disallow landowners from adding fill material into designated wetlands within their lots. Staff has suggested several conditions to minimize impacts to the sites vegetative assets. I. Assessment / Fees The property is located in the RE -1 School District which requires either a land dedication or payment of cash -in -lieu of School / Land Dedication Fee. The Applicant is responsible for paying the fee at the time of final plat. This obligation shall be memorialized in the Subdivision Improvement Agreement. The property is also located in the Carbondlae Fire Protection District which requires an impact fee to be paid at the time of Final Plat. I. Development in the 100 -Year Floodplain Review A portion of the property, primarily along the Roaring Fork River, is located in the 100 - year floodplain. Since this proposed application represents a PUD and preliminary plan, the Applicant is required to address the floodplain issues on the property which is 57 generally reviewed by the County in an administrative review for development in the flood -fringe, which is done as a part of this review but still requires a separate Administrative Floodplain Permit. As per the federal Emergency management Agency (FEMA) Flood Insurance Rate Map, Garfield County, Colorado, Unincorporated Areas, Map # 080205 1880 B, portions of the property lie within the "flood fringe" of the 100 year floodplain. Several home sites on the southern portion of the property are located in the existing 100 year floodplain. These sites will be elevated to a minimum of one foot above the 100 year base flood elevation. Designated finished floor elevations in this area are at a minimum of 1.5 feet above the 100 year base flood elevation. No proposed building will be built within the 100 year floodway. 1. A plat note should be included on the final plat of the TCI Lane Ranch PUD that states the specific lot number building areas or envelopes which have been filled, references the floodplain development permit number, and indicates that construction on these lots must conform to the CARCO Floodplain Regulations and the approved permits. 2. A plat note should be included that indicates the minimum finished floor elevation for each lot within the flood fringe area. VII. STAFF RECOMMENDATION & PROPOSED FINDINGS REGARDING THE PROPOSED REZONING TO PUD Staff recommends the Planning Commission recommend approval to the Board of County Commissioners to rezone to Planned Unit Development (PUD) with the following findings of fact: 1) That the hearing before the Planning Commission was extensive and complete; all pertinent facts, matters and issues were submitted; and that all interested parties were heard at those hearings; 2) That the proposed PUD does generally conform to the County's Comprehensive Plan of 2000, as amended; 3) The proposed use is in the best interest of the health, safety, morals, convenience, order, prosperity and welfare of the citizens of Garfield County. 4) The applicable sections of the County's Zoning Resolution of 1978, as amended have been met. 5) That the Applicant shall comply with the following conditions listed below: 58 VIII. STAFF RECOMMENDATION & PROPOSED FINDINGS REGARDING THE PROPOSED PRELIMINARY PLAN Staff recommends the Planning Commission recommend approval to the Board of County Commissioners for the Preliminary Plan Application with the following findings of fact: 1) That proper publication, public notice, and posting was provided as required by law for the hearing before the Planning Commission; 2) That the hearing before the Planning Commission was extensive and complete; all pertinent facts, matters and issues were submitted; and that all interested parties were heard at those hearings; 3) That the application is in compliance with the specific standards set forth in the Garfield County Subdivision Regulation of 1984, as amended; 4) The proposed use is in the best interest of the health, safety, morals, convenience, order, prosperity and welfare of the citizens of Garfield County. 5) That the Applicant shall comply with the conditions listed below: IX. CONDITIONS OF APPROVAL 1. WILDLIFE: The Covenants shall contains the following provisions: a. Fencing should be held at a minimum and any necessary fencing should be wildlife friendly. For wire fencing, 42 inches for a maximum height, 4 wires at most with a 12" kick space between the top two strands. Rail fencing should be 48 inches or less with at least 18" between two of the rails. b. The riparian areas along both the Roaring Fork River and Blue Creek are extremely important to wildlife. f Elk usage of the property has increased considerably during the winter months. Deer and elk conflicts are to be expected within the development and plantings of native vegetation are encouraged to help reduce some of those conflicts. Eliminating the plantings of any berry, fruit, or nut producing plants or shrubs will help discourage elk, deer, bears and other wildlife from feeding upon the landscaping. Homeowners need to be aware that the Division of 59 Wildlife is not liable for any damage to landscaping by deer, elk, or bear. iv. Bear/human conflicts have increased within the Roaring Fork Valley and in the vicinity of Blue Creek Ranch and Catherine Store. This has the potential to be a reoccurring problem. It is important that certain measures be taken to minimize these possible conflicts.- a, onflicts: a. Homeowners have and use an approved bear -proof container for storing all trash/garbage; b. Pets should be fed indoors, and pet food or food containers should not be left outside,- C. utside;c. BBQs should also be securely housed in the garage or cleaned with a bleach solution when not in use due to the fact that leftover food and grease are an overwhelming bear attractant; d. Round door knobs on the outside of doors rather than lever - type can limit bear access into houses. v. The proposed pedestrian bridge over the Roaring Fork River should be gated to prohibit access to the RFTA during the winter closure period. vi. Due to the critical nature of wetland areas for wildlife, it is recommended that any proposed trails or paths be minimized and the public access into these areas should be limited in numbers. Access should be closed completely from December 1 through March 15 in order to limit the disturbance on big game and wintering bald eagles utilizing the riparian corridor. 2. VEGETATION /WETLANDS a. As part of the public improvements to be constructed by the Applicant and secured in the Improvements Agreement as part of the Final Plat application, the Applicant shall construct a fence to a design specification consistent with the BLM's needs regarding preventing access to the BLM parcel in the southeast portion of the development. b. Where trail design indicates that the trail crossing the wetland area will be a 2' Natural Surface Path, Staff requests further clarification on this type of path. Garfield County Vegetation discourages the construction of any type of trail that would bring imported fill material into the wetland area. c. The Applicant shall provide an "orchid monitoring program" and a plan that that will maintain the open wetland areas. .E d. Staff has concerns about potential conflicts with Ute's Ladies Tresses habitat that need to be better analyzed by the Applicant prior to the hearing before the Board of County Commissioners: 2. Portions of Riverstone Drive and how will Riverstone Drive cross the wetland without altering the water flow and the hydrology? 3. T_wD_lots on the north end of Dragonfly Spur (lots 56 and 57). 4. What are the future plans to channelize Blue Creek and if channelization occurs, will the area would become less saturated and spiranthes habitat would become diminished. 3. AFFORDABLE HOUSING a. The Applicant shall be required to provide 9 deed -restricted single-family affordable housing units on Lots 1, 11, 12, 18, 25, 26, 28, 29, and 39. These units shall be governed / administered by the Garfield County Housing Authority. The Final Plat shall note these lots as AH Units on the plat. The Applicant shall meet with the Garfield County Housing Authority prior to Final Plat to ensure that the required deed restriction meets the requirements of the Garfield County Housing Authority. b. The Final Plat and protective covenants shall contain 'roIlowing note `7n order to ensure the orderly and timej-y-66nstruction of the 9 required deed -restricted affordable housing uarts, no more than 10 free market unit building permits shall be issyj9d'by the Garfield County Building and Planning Department at qpy-one time unless a building permit has been issued for a deed-restridted affordable housing unit such that a ratio of free-market to affraidable housing units shall be constantly maintained of 10 free-market do one (1) deed restricted unit. " "o - 4. o — , 4. OFF-SITE IMPROVEMENTS TO CR 100 / STATE HIGHWAY 82 INTERSECTION a. The Applicant shall construct the improvements to the intersection of CR 100 and State Highway 82 as approved by CDOT which includes a new 61 \�r l 'N N, right turn lane from northbound CR 100 to the up valley direction of State Highway 82. Additionally, the applicant will construct a raised median between the northbound and southbound directions on CR 100 (within the SH82 ROW) adding additional safety to the turning movements. These improvements are to be paid for exclusively by the developer within the context of the Improvements Agreement. (This final design approved by CDOT shall be included in the Final Plat application.) 5. 100 -YEAR FLOODPLAIN The Applicant shall obtain an Administrative Floodplain Permit from the Building and Planning Department prior to the submittal of the Final Plat. The Final Plat shall show the first finished floor elevation (FFFE) on each building envelope on the Final Plat that lie within the 100 -year flood fringe. 6. ZONING DIMENSIONAL REQUIREMENTS This approval of the PUD shall allow the following variances from the dimensional standards in the ARRD Zone District and provisions in the Subdivision Regulations of 1984: A. Reduction in minimum lot size per the site plan; B. Allow duplex as a use -by -right instead of a conditional use; C. List pipelines under conditional use permit subject to pipeline regulations rather than list under use -by -right; D. Reduction in the ROW width on the main entrance roads (Haystack Road and Riverstone Drive) from 60 feet to 50 feet; E. Allowing "community building" as accessory use to the residential development; F. Allowing Dragonfly Spur to exceed the 600 linear feet maximum for cul-de-sac by 200 feet; and -A-redtrct1an tn' the off-street parking for the community buil ing 1 space er J 7. DRAINAGE The Final Plat shall address the following drainage questions raised by the County Project Engineer: 62 A. Watershed. The Historic Basin has been divided into six (6) existing sub - basins based on contour mapping, survey information and field investigations. This will generate runoff in addition to the volume calculated within the development on a pre -post calculation methodology using the rational method derived from the SWMM program of intensity, duration and frequency. B. Treatment of Stormwater Runoff. Water quality treatment for storm water is discussed within the Preliminary Plan. In order to protect the water quality in Blue Creek and the Roaring Fork River, it the county's expectation that all runoff from roadways, parking areas, roofs, and similarly developed areas will be treated using best management practices of retention basins and sedimentation swales as per the submitted improvement plans. Wetlands. Neighborhood "D" of Firefly Loop (Lots 60 through 64), Dragonfly Spur (tots, 56 and, -&7) and Ma�yf Bend -(Lots 66; -67, 68 and, 69) indicates lot areas that could'possi6ly cor(taining wetlands. Building -envelopes should be revised in these wetland areas after a defined area of wetlands boundaries have been determined. D. Depiction of Offsite Water Pipeline to Development — These plans will be prepared by the Applicant's engineer and reviewed by the Mid Valley Metro District's engineer. The main issue to the County is proof that CDOT will allow the utilities in the Highway 82 ROW and whether there is adequate room in the ROW for both the water and sewer line. E. Depiction of Offsite Sewer: Same comment as for the offsite water lines. 8. GEOLOGY The Final Plat and covenants shall contain the following plat note to address potential sinkholes.- "if inkholes. "if conditions are indicative of sinkhole related problems are encountered during site specific soil and foundation studies for the houses and other movement sensitive facilities, an alternative building site should be proposed or the feasibility of mitigation evaluated ... Prospective homeowners should be advised of the sinkhole potential, since early detection of building distress and timely remedial actions are important in reducing the cost of building repair and should an undetected subsurface void start to develop into a sinkhole after construction." 9. IMPACT FEES A. The development is subject to development impact fees adopted by the district. The developer will be required to enter into an agreement with the 63 \r �N C ti District for the payment of development impact fees. Execution of this agreement and payment of the fees are due prior to the recording of the Final Plat. Fees are based upon the impact fees adopted by the District at the time the agreement s executed. The current fee for residential development is $704.00 per unit. B. The Applicant shall be required to provide a school land dedication or fee in lieu of dedication to the RE -1 School District at the time of Final Plat pursuant to the requirements in the Garfield County Unified Land Use Resolution of 2008, as amended. This fee is collected at the time of Final Plat. W� �— Jj
