GENERAL SITE INFORMATION A. Property Location The property is generally located in the western ' of Sections 7 and 18 of Township 7 South, Range 88 West and in the eastern half of Sections 1 and 12 of Township 7 South, Range 89 Glenwood Springs Carbondale 1 BOCC April 18, 2016 DP West. More practically, the property is located 2.5 miles south of Glenwood Springs east and adjacent to State Highway 82 (SH 82) with a proposed primary access point located north of Cattle Creek Road (CR 113) as it intersects with SH 82 in the lower Roaring Fork Valley. Properties to the north include two commercial parks (Eastbank & Evergreen) and a high-density mobile home park (H Lazy F). Properties to the west include a medium -density (Teller Springs) and medium -density (Iron Bridge) residential development. Properties to the south include an active gravel extraction operation (LaFarge). Properties to the east include a variety of commercial businesses (Van Rand Park), and a high-density mobile home park (Mountain Meadows Court). B. General Property Description The property contains approximately 160 -acres of former 281.62 acres site that was subdivided into several >35 -acre parcels. The subject site is located on the floor of the Roaring Fork Valley and is configured in a linear north -south orientation with the Rio Grande Trail/RFTA corridor forming its east border and the Roaring Fork River forming its western border. Physically the property can be characterized by several benches that step down in an east to west direction towards the Roaring Fork River. A perpetual conservation easement held by the Roaring Fork Conservancy is located adjacent to the subject site of this application and along Cattle Creek. Beyond what has been protected in the adjacent easement, the entire property has been virtually denuded of any viable vegetation and stripped of much of its topsoil as a result of former development attempts by a previous owner which has left the property in poor condition. The ground cover is primarily characterized by cobles and gravel with three or four large piles of unanchored topsoil. Some rough grading work is also evident where the previous owner had begun to rough in a golf course. C. Property History The Sanders Ranch Planned Unit Development (PUD) was approved by the Board of County Commissioners (BOCC) in 2001 with a site specific development plan that included a golf course, 62 single-family dwelling units and 168 multi -family dwelling units for a total average density of 1.22 acres / du or conversely, 0.81 du / acre. Subsequently, the owner of the property at the time (Sopris Development Group) sold the property to Linksvest / Bair Chase, LLC who submitted a Preliminary Plan Application in 2003 based on the PUD which was approved by the BOCC in 2004 and extended in 2005. The net result was that the Preliminary Plan Application became invalid due to expiration; certain obligations / timeframes contained within the Phasing Plan in the PUD also became invalid thus rendering the entire PUD Plan invalid. 2 In February, 2008 the Board of County Commissioners revoked approval for the uncompleted portion of the PUD and rezoned that portion to Residential Suburban (known as RGSD under the Zoning Resolution of 1978, as amended) leaving the area encompassed by the conservation easement held by the Roaring Fork Conservancy zoned as Open Space / Conservation District in the Sanders Ranch PUD as shown right. BOCC April 18, 2016 DP Open Space Conservation District in Sanders Ranch PUD In October 2008 the site was owned by River Bend, LLC when Related WestPac, LLC submitted an application for a Zone District Amendment for Planned Unit Development (PUD). This PUD proposed 1,006 dwelling units, 30,000 square feet of commercial, a school site, open space and recreation as shown on the development plan below. River South Neighborhood , River No .� Neighborhood' This application was subsequently withdrawn by the Applicant prior to any action taken on the request. 3 BOCC April 18, 2016 DP II. RIVER EDGE COLORADO (REC) PROJECT DESCRIPTION The current owner of the site, Carbondale Investments, LLC, (CI) was approved to rezone a portion of the original site discussed above, from Residential Suburban to PUD to allow for development of 366 dwelling units (including 55 affordable units), 30,000 square feet of public, quasi -public and commercial floor area, open space and recreation. The owner was also approved for a Preliminary Plan Application to allow for subdivision of the site. The 2011 application materials contained the following project description: CI contemplates developing the property into a walkable clustered -form of residential development with 366 residential units of various sizes and types, including 55 affordable homes, passive and recreational open space, and a neighborhood center (collectively, the "Project"). The neighborhood center will serve as a central gathering place for residents, and will offer opportunities for several neighborhood amenities, such as, meeting rooms, offices, a fitness room, a community kitchen, restrooms, other indoor and outdoor recreational facilities, and limited community service uses. Community service uses may include not-for-profit or for profit uses that may be operated for the benefit of residents of the community only within designated spaces of the neighborhood center. Community service uses shall be operated by a tenant or concessionaire of the property owners' association (the "POA') to be established for the Project and may include, without limitation, a day care facility, a sandwich/coffee shop, and/or a health club. Park areas, which will be provided internal to the Project (and away from the RFC Conservation Easement), will offer opportunities for informal recreational opportunities, such as, tot lots, dog parks, playfields, and a trail system. In addition, in keeping with the Property's agricultural heritage and rural character, CI anticipates that areas designated on the River Edge Colorado Planned Unit Development ("PUD") for "Garden/Orchard" use may be used, at the residents' election, as communal vegetable gardens and/or orchards. Subject to any rules and regulations of the POA, it is anticipated that these Garden/Orchard tracts will consist of individual plots, multiple caretaker areas, sitting areas, small-scale children's play areas, other ancillary horticultural related uses, and for community festivals and celebrations. The amenities to be provided within the neighborhood center, garden and orchard tracts, and park areas ultimately will be decided by the residents of the Project. It is also anticipated that certain agricultural uses will continue to be allowed within portions of the Property not under development, as specified in the River Edge Colorado PUD Guide provided in Tab 3, Item b. of the PUD/Preliminary Plan Application. 4 BOCC April 18, 2016 DP The Applicant originally proposed that the development proceed in 11 phases with reclamation of the entire 160 -acres being completed in Phase 0. The development was anticipated to be built - out in 2019 based upon an average annual absorption rate of 58 units per year. The Applicant was requesting a vesting period for the development for a period of 10 years. PHASING In 2011 the staging and timing of the proposed development was described as: The Project is proposed in several stages or filings. There are 6 filings and 5 subfilings. The Project will be constructed over a period of 5-10 years. The development stage of the Project is preceded by a pre -development reclamation phase described in the Reclamation Plan (Appendix U of the Impact Analysis, Binder 2 of the PUD/Preliminary Plan Application). The development staging and construction is detailed on Drawing No. CPO1.01 of the PUD (Rezoning) and Subdivision (Preliminary Plan) Drawing Package submitted as part of the PUD/Preliminary Plan Application. Phase 0 - This first phase was to reclaim the site in preparation for development activities. This Plan proposes and details a pre -development reclamation action ("Phase 0"), including grading, necessary to repair the damage to the Project Site resulting from actions taken by Bair Chase in association with the Sanders Ranch PUD which partially regraded the Project Site (as hereinafter defined) for residential and golf course development and stripped and stockpiled the topsoil. 5 BOCC April 18, 2016 DP 2011 Phase 0 Improvements The description of the reclamation is basically a `grading program' but also included: • Relocation of the Rio Grande Trail at the entry to the site. The Applicant stated that this relocation will be done in coordination with RFTA and would result in a grade - separated trail that will reduce or eliminate potential conflicts between trail users and access to the site. • Relocation of the Glenwood Ditch to facilitate property development. • Site grading included movement of 1.2 million cubic yards of material which will re - grade the site for proper drainage and resolve existing and potential geotechnical hazards. In addition this would also repair and stabilize eroding steep terrace escarpments, and repair active and stabilize stream bank erosion. • Construction of drainage facilities and water quality detention ponds. • Final revegetation and planting of vegetative screens along the Rio Grande Trail and the conservation easement. Phase 1 — 59 lots (39 "Town" lots and 20 "Attached" lots); off-site infrastructure such as access from Highway 82, a private at -grade crossing over the grade separated-RFTA trail, connection to water and wastewater treatment facilities if service is provided by RFWSD. On- site improvements include the round -about and streets to serve the lots, bridge over Cattle Creek, water and sewer lines, parking and mailboxes at the Community Center Phase 1B — 26 lots (13 Garden Homes and 13 Affordable Homes). These first two phases are anticipated to be constructed between 2012 and 2014. Phase 2 — 31 lots (12 Village Lots, 19 Attached) Phase 2A - 56 lots (28 Garden Homes and 28 Affordable Homes). Phase 3 — 36 Lots (35 Town Lots and 1 Village Lot) Phase 4 — 52 Lots (44 Town Lots and 8 Village Lots) Phase 4A — 19 Garden Home Lots Phase 5 - 27 Town Lots Phase 5A - 28 Lots (14 Garden Home Lots and 14 Affordable Homes) Phase 6 — 61 Lots (9 Estate Lots, 17 Town Lots and 35 Village Lots) 6 BOCC April 18, 2016 DP 111. PROPOSED AMENDMENTS The Applicant is requesting the following amendments to the PUD and Preliminary Plan as approved: Carbondale Investments requests an amendment to the Preliminary Plan and PUD Plan to accommodate the relocation of the access to and from State Highway 82. The new access point will move north from River Edge Drive to a new roadway known as Terrace Parkway and will provide access to both the Project and the GCCI property through a single access road. The creation of Terrace Parkway results in a new layout of the Project's intersection with State Highway 82 and a modification of the Project's internal streets. The Amendment largely maintains overall density, with a slight reduction from 366 residential units to 362. The Amendment also: creates a new Rio Grande Trail crossing and related improvements for Terrace Parkway; eliminates the River Edge Drive Right -of -Way extension to State Highways 82 and related plat adjustments; creates new trail connections and/or crossings of State Highway 82 at the old access location; relocates the secondary emergency vehicle access onto State Highway 82 to run through adjoining properties to the north of the Project to connect to County Road 167; reorganizes the Subdivision Filings as reflected on the Preliminary Subdivision Plan; and revises the PUD Phasing Plan to shift earlier phases of development to the vicinity of the new access point. The Amendment is otherwise largely consistent with the current approved Preliminary Plan and PUD Plan. Overall open space will increase by 0.1 acres (to 40.60 acres), total common area will remain at 16.89 acres, and total parks will increase by 0.26 acres (to 17.34 acres). The Amendment maintains the same affordable housing ratios as previously approved and the majority of affordable housing units will now be developed in the first five Subdivision Filings, with Subdivision Filing 1A now including 28 of the 55 units.

However, because the Applicant had a pre -application conference on the aforementioned amendments prior to this expiration date, Staff considered this step the beginning of the application process. In addition, the Development Agreement, which became effective on December 22, 2011, was valid for a period of five years. As approved, the Development Agreement will expire on December 22, 2016, unless the Applicant pulls a building permit by this date. As a result, and in addition to the requested modifications, the Applicant is requesting to reset the timeframes for the Preliminary Plan and Development Agreement in this amendment application. If approved, the amended Preliminary Plan would have a three year timeframe starting, presumably, in 2016 and extending through to 2019. Meanwhile the Development Agreement would have a five year timeframe starting, presumably, in 2016 and extending through to 2021. 9 BOCC April 18,2016 DP Revised Preliminary Plan ,• 11 5 14 N ,1 1 i 1 nt 1 1 i i : 11P ilt!!hilt I 1 1111111 \I‘ I" !III 13 • 0 • ICOC.1.16.1140,1 14.4 S.Mal l^33•1110, IdallS,rat NOM 11.1 10 BOCC April 18, 2016 DP IV. REFERRAL AGENCIES The Amended PUD and Subdivision Preliminary Plan applications were referred to the following agencies and County Departments for their review and comment. Comments that were received are briefly noted below and more substantively included in the body of the memorandum. a. Colorado Department of Transportation: (Exhibit 12 and Exhibit 25) Ken Brubaker: Bicycle and Pedestrian Facility Engineer. (Review Limited to Proposed Bicycle and Pedestrian Underpass crossing Highway 82) "The existing structure does not meet the horizontal or vertical clearance requirements for a pedestrian or multiuse path underpass. Underpasses should be wide enough and tall enough to invite use and to provide a sense of security when in use. As proposed this structure would be dark, intimidating, and feel claustrophobic. The recommended minimums for a structure such as this in a rural area is 12' of width and 10' of vertical clearance. A structure of this length would ideally be even wider and taller than those required minimums." "If this structure is intended for bicyclist and pedestrian use then it should be designed to shared -use facilities standards. The approach to the structure does not meet the minimum width required for a shared -use path. The minimum width requirement for a shared use path is 10'." "The proposed plans do not show any lighting being provided through the underpass. It is unlikely that a structure of this length would be appropriately lit without illumination. Guidance regarding selection of lighting for tunnels and underpasses can be found in the AASHTO Informational Guide for Roadway Lighting or CDOT's Lighting Design Guide." Dan Roussin: Permit Unit Manager. - Noted that an access permit has been issued for River Edge PUD with a traffic volume of 275 design hourly volume. - Noted that "The thought with this permit is to provide a full movement public intersection with the potential for signalization in the future. The permit states this would be designed as a non -signalized continuous green intersection. It is anticipated once Garfield County Commercial Investments, LLC property develops, a signal will be warranted. This signal is anticipated to work long-term with the future signal at Cattle Creek/ SH 82 intersection. Therefore, both intersection would be long-term be Signalized Continuous Green Intersection. The intent of this configuration was to make the signals at River Edge Colorado intersection and Cattle Creek Intersection operate as one signal." - Noted that the grade separated bicycle / pedestrian crossing of Highway 82 is vital to the concept of the Continuous Green Intersection. In addition, Mr. Roussin notes that "It is anticipated that this cattle crossing would be upgraded to accommodate pedestrians. CDOT recognizes the cattle crossing box culvert doesn't meet any current standards for pedestrian underpasses." - Regarding maintenance of the underpass, Mr. Roussin notes "The Pedestrian Underpass shall be maintain by either Garfield County or Cattle Creek Metropolitan District. CDOT will not maintain this structure. Therefore, CDOT will require an agreement for the maintenance and operation of the underpass." Regarding the southern Emergency Vehicle Access (EVA) onto Highway 82, Mr. Roussin notes "CDOT has discussed with the River Edge Colorado representative 11 BOCC April 18, 2016 DP about the possibility of providing emergency vehicle access on SH 82. With the information provided, it very unlikely CDOT would approve an emergency vehicle access for this development on SH 82. CDOT would recommend that the Applicant work with surrounding landowner to provide emergency access." b. SGM-Inc: (Review Limited to Proposed Bicycle and Pedestrian Underpass crossing Highway 82) (Exhibit 13) - "This type of intersection (Highway 82 and Cattle Creek) is not conducive to pedestrian crossings because the mainline operates with continuous flow. Therefore, a grade separated crossing, such as an underpass, is more appropriate at this location." - "...cyclists and pedestrians who want to go from the Rio Grande Trail to Cattle Creek Road currently have to cross four lanes of SH -82 at grade at this existing access point." - "Any proposed improvements in this area should consider these uses (cyclists) and provide a crossing that is safe, usable and inviting as a connection between these multi- use facilities." c. Garfield County Housing Authority: (Exhibit 21) Noted a possible reduction in the number of affordable housing units due to the reduction in the overall number of units. Noted that the comments from the original Preliminary Plan approved in 2011 have not been addressed. d. Garfield County Vegetation Manager: (Exhibit 20) Noted that the property owner conducted weed treatment for County listed noxious weeds in early summer with a follow-up in late summer. It is suggested that the property owner conduct at least two treatments in 2016 with treatment records sent to the Vegetation Management Department by October 31, 2016. Recommends that item 5 of the Open Space and Management Plan (OSMP) be deleted. This Item 5 states that "weeds that occupy 5% of the foliar cover shall be treated in accordance with the State Noxious Weed Act." As a 5% cover is not acceptable, this statement needs to be deleted. e. Garfield County Engineering Department: (Exhibit 17) - Noted that the trail through the underpass needs to be adequately connected to the internal REC trail network. In addition, the trail needs to connect to the County road network on the east side of Highway 82. - If boring under Highway 82 is required for the utilities, then the necessary Garfield County and CDOT permits must be obtained. More information is needed on where this boring will go and the size of the boring. The separate package for utilities crossing Highway 82 could not be found. The installation of these utilities should be coordinated with future County project at the Cattle Creek intersection. f. Colorado State Division of Water Resources: (Exhibit 23 and Exhibit 27) - Noted that the proposed source of water is to be provided through the Roaring Fork Water and Sanitation District. The Division maintains that the "proposed water supply will not cause material injury to decreed water rights so long as the Applicant and District operate the water supply in accordance with the decreed terms and conditions in cases 01 CW 187, 07CW164 and 08CW198. In addition, so long as the Applicant continues the pre -inclusion agreement with the District that allows for utilization of the District's infrastructure, this office finds 12 g. BOCC April 18, 2016 DP that the proposed water supply will be physically adequate." - Noted that the Division has no record of permitted water wells on or nearby the "Executive Lot". Garfield County Road and Bridge: (Exhibit 24) - Noted that the north emergency vehicle access does not access directly onto a County road and as a result, does not require County permitting. - Noted that the north emergency vehicle access crosses several parcels in different ownership. The Applicant will need to demonstrate legal access across all ownerships from the end of the access to County Road 154. - Requested details on how the trail coming from the bicycle / pedestrian underpass will tie into the County road system. - Requested details on which agency will take ownership and maintenance responsibility for the bicycle / pedestrian underpass. - Noted that the Cattle Creek and Highway 82 intersection is currently a safety concern. Moving the access to the north could increase the physical scope of the traffic concerns. h. Garfield County Attorney's Office: (Exhibit 26) The draft easement for Terrace Parkway is acceptable, but must be executed and recorded prior to issuance of a grading permit. The Applicant needs to finalize agreements with RFTA and CDOT to obtain legal access to the site at this location. Recommends a condition of approval requiring that the CDOT and RFTA permits/licenses be received and reviewed by the County Attorney's Office prior to final approval of the amended Preliminary Plan and PUD. - The easement that was to demonstrate legal access from the H Lazy F mobile home park to County Road 154 is difficult to understand. In addition, the referenced Exhibit C, which is understood to be a map of the easement area, was never recorded. Further, Recital C of the Easement references County Road 167, which appears to be erroneous. If the easement connects with the private roads owned by private parties, then additional easements may be required. It is recommended that the Applicant revise this easement to better depict the easement granted and attach and record Exhibit C. Significant changes were not made to the PUD Guide from that approved in 2011. The Applicant has requested that the Memorandum of Understanding (MOU) as recorded at reception number 824971 be terminated with a "Certificate of Completion". The MOU appears to be satisfied "since the proposed access point for the subdivision has moved and REC has paid its share of expenses as agreed to by the Board." However, since the entire MOU was never "completed", a mutually agreed upon termination is more appropriate. "The Board will need to determine if a new Memorandum is needed for any potential issues with the new access point for the subdivision. Staff does not believe any outstanding issues exist, and as such, no new Memorandum is needed. Prior to termination of the MOU, further discussion with the Applicant and the Board is needed to determine if there are any remaining issues, improvements or cost sharing needed." The pre -inclusion agreement with the Roaring Fork Water and Sanitation District (RFWSD) includes both the subject parcel owned by Carbondale Investments (CI) as well as the adjacent property owned by Garfield County Commercial Investments (GCCI). "The tethering of these two properties under this agreement is difficult. The ability of the subdivision to supply water is now tied to a second parcel. This is not ideal. I recommend that the Applicant revise its Agreement with RFWSD to remove the GCCI services." It is understood that an amended service plan may be submitted to Garfield County "to differentiate between residential services for the subdivision and commercial services for GCCI." 13 BOCC April 18, 2016 DP Should expansion of water and/or sewer treatment facilities be necessary, then a Location and Extent review through Garfield County may be necessary. - The prior Development Agreement includes a provision which allows the "Developer to alter the sequence of Filings set forth in the Phasing Plan" and have these amendments be "treated as a non -substantial modification to the REC PUD". Ms. Cave states that "I do not approve of the Developer's right to alter the sequence of Filings as a non - substantial modification that does not require a hearing and is solely determined by the Director." The current Code states that any change to phasing is a substantial modification. The Phase 0 Improvements Agreement, Recital 6, references the Construction Phasing Plan but the Plan is not attached as to the Agreement as an exhibit. "The Applicant wishes to delay production of these plans until it applies for a grading permit. I do not support this request, as the Construction Phasing Plan is clearly tied to the execution of the Phase 0 Improvements Agreement. The Board needs to understand the full extent of these improvements prior to accepting and executing this Phase 0 Agreement. If the Board approves of the delay, I recommend a condition of approval for staff to review the Construction Plans and for Applicant to record same with the filing of the final plat." The Phase 0 Improvements Agreement, Recital 7, adds a third party agreement with Cattle Creek Metropolitan District. "A draft of such agreement and further explanation of how the landowner and District are incorporated is needed." - "Additional language has been added to the Indemnity provision of paragraph 4. I recommend deleting this addition since it brings in Third Party Entities. The County is responsible if its employees are negligent, but not if Third Party Entities or their employees are negligent. That is a decision for a court to make." - It is unclear which Land Use Code applies to applications for future review by the County. "In order to clarify future County involvement with the subdivision, I recommend a condition of approval that the applicable code be stated in the Preliminary Plan Resolution. Staff's suggested language is "All future amendments shall be reviewed pursuant to the Land Use Code or Resolution in place at the time of submittal."" i. Carbondale Fire Protection District: (Exhibit 19) Noted the development is to have two Emergency Vehicle Accesses (EVAs), one on the south end connecting to Highway 82 and another on the north end connecting to H Lazy F Mobile Home Park. Noted that the proposed water system with service provided by the Roaring Fork Water and Sanitation District is acceptable. In addition, the fire hydrant locations are acceptable. Noted that the developer will be required to pay an impact fee of $730 per unit to the District. J• Roaring Fork Transportation Authority (RFTA): (Exhibit 14) Noted that the main access and south EVA are required to obtain approval from the RFTA Board of Directors and the Colorado Public Utilities Commission (PUC). - "By virtue of previous agreements, the developer is committed to provide a grade - separated trail connection at the main vehicle access to the development, but is seeking relief from that commitment. Ultimately, the RFTA Board will need to determine whether such relief will be granted. RFTA is working closely with the developer with respect to its requests for vehicle and utility crossings." - "Regarding transit, the approximately 360 residential units and the potential commercial development to the north will likely create demand for transit services in an area that does not contribute sales tax revenue to support the service. Moreover, the new development will potentially siphon off sales taxes for transit from other areas." 14 BOCC April 18, 2016 DP Noted that RFTA has a Service Expansion Policy in place and that "RFTA is willing to work with Garfield County and the Applicant to forecast the potential transit demand, and then estimate the capital and operating costs." Noted that the RFTA Board will get to a decision on the REC crossing in February or March of 2016. (Exhibit 18) k. Mountain Cross Engineering: (Exhibit 22) Easement not executed for main access to property. Noted that application proposes two options for water to the property: "either connection to the Roaring Fork Water and Sanitation District (RFWSD) or providing their own community system. The application materials seems to provide enough evidence that there is a legal supply of water, however the physical supply is still pending negotiations. There are requirements that the Applicant would need to meet with either option: well pump test, water quality test, community water system approvals with CDPHE, among others if the Applicant were to provide their own system; and evidence of adequate capacity of the systems of RFWSD if connecting to them. Other land use approvals may be necessary to provide a physical supply." - "...the sewer treatment system has not been determined; either connection to RFWSD or providing their own community system are the two options. Connection to RFWSD may require a crossing of the Colorado River. Permitting and design were not included in the application materials." - Noted that the bridge over Cattle Creek may require a floodplain permit and/or LOMR. The Notice to Proceed for the main entrance to Terrace Parkway has not been issued. "...the Applicant does not provide sufficient evidence that RFTA has approved the RFTA crossing of Terrace Parkway at the proposed relocated entrance." - Requested that the Applicant clarify when signalization of the main entrance may occur. "Since the main entrance is proposed to be removed from Cattle Creek, the Applicant proposes to remove their responsibility for the improvements to this intersection. It is unclear how the improvements proposed to the Cattle Creek intersection will be permitted and/or constructed." Noted that an Access Permit has not been issued by CDOT for the southern Emergency Vehicle Access onto Highway 82. - Noted that additional parking should be provided at the ball fields and playgrounds. - Noted that the traffic calming island of the roundabout eliminates turning movement onto Moraine Court from Riverside Loop Drive. Noted that "The project site grading along the north property line shows incomplete contours, trespass on the adjacent property to the north, and creates drainage ponding areas. The Applicant should revise the grading plan and obtain any necessary agreements and/or temporary easements." Noted that driveway permitting may be required for the northern Emergency Vehicle Access onto County Road 154. - "The cost estimates do not appear to include soft costs, such as construction observation, testing, surveying, etc. The Applicant should verify that these should be included. A more detailed itemization of the individual costs would usually be required to justify security amounts for an SIA." - Noted that "The proposed pedestrian underpass seems to be incongruent with typical pedestrian underpasses. The existing box culvert is 7' tall by 6' wide and would be approximately 150 feet long. No lighting appears to be proposed. The Applicant should provide an analysis on the adequacy of the structure as a proposed underpass." - Requests that the Applicant "design the release structures and routing for discharges from the water quality ponds." 15 BOCC April 18, 2016 DP Requests that the Applicant provide "The plans and specifications concerning sewer and water [that] will need to be approved for construction by RFWSD if that option is pursued." - Noted that the storm drains are not labeled on the plans. Noted that "The storm drainage will need to be revised for the offsite flows flowing from the GCCI parcel get into culvert c76 -a." Requests that the Applicant show how the fire hydrants throughout the development are connected to the water lines. Noted that the water line on Trailside drive conflicts with the Glenwood Ditch piping. - Noted that the water line on Trailside Drive conflicts with the 36" storm drain culvert. - Noted that construction will require a National Pollution Discharge Elimination System (NPDES) permit from CDPHE. - Noted that "The southern EVA access proposes an 8% slope to SH 82. This would be incongruent with CDOT standards and may need to have the design revised." Noted that "The engineering plans provided are preliminary. Construction drawings are proposed to be submitted at time of the Final plat. Review of the Construction Drawings should be required at that time." I. U.S. Army Corps of Engineers: (Exhibit 15) - The Applicant needs to obtain verification of the wetland delineation. m. Colorado State Forest Service: (Exhibit 16) - Noted that the wildfire rating for the property is Low to Moderate - Recommends that the Colorado State Forest Service Defensible Space Standards be required for all structures within the proposed development. n. Roaring Fork Water and Sanitation District: (Exhibit 28) - Noted that it is unclear whether the Applicant intends to connect to the District for both water and sewer. As a result, the District has not conducted a detailed review of the proposed Preliminary Plan or PUD. - Noted that the District has committed to serve the development with water and sewer service through the terms of the Pre Inclusion Agreement. No comments were received from the following agencies: o. Garfield County Emergency Management p. Garfield County Public Health q. Soil Conservation District r. Glenwood Ditch Company s. City of Glenwood Springs t. Town of Carbondale u. Colorado Parks and Wildlife v. RE -1 School District w. Garfield County Sheriff Department x. Roaring Fork Conservancy 16 V. GENERAL RELATIONSHIP TO THE COMPREHENSIVE PLAN One component of the Comprehensive Plan is the Future Land Use Map which designates density ranges and uses that may be considered appropriate for an area. BOCC April 18, 2016 DP This site has been subdivided from the original 288 -acres as indicated on the map at right into a property shown above that consists of 160 -acres of the original parcel. The Roaring Fork Conservancy Conservation Easement is not included in this application and will remain a separate parcel zoned Sanders Ranch PUD, Open Space. The River Edge Colorado PUD was approved in 2011 under Resolution 2011-84. This approval stated that the proposed PUD conformed to the Comprehensive Plan of 2030. According to the Applicant: Like with the Preliminary Plan, the Board has already determined that the PUD Plan "meet[s] the requirements, approval criteria, and standards set forth in the ULUR" and is in "general conformance with the Garfield County Comprehensive Plan 2030," "subject to compliance with the conditions of approval set forth in [Resolution 2011-84] and except where waivers have been granted." Resolution 2011-84. Density in the Amendment falls well within the residential density range contemplated by the Comprehensive Plan for the Residential High designation. The Project will continue to offer affordable housing, a diverse mix of housing types at a range of prices, a significant area devoted to parks, trails, and open space for Project residents, and preservation of the County's rural character and views. See Comprehensive Plan at pages 23 & 27. Sections of the Comprehensive Plan that are relevant to the application are excerpted below. Chapter 2. Future Land Use includes the following direction: Future Land Use Map The Future Land Use Map designates the site as Residential High Density which provides a `range' of appropriate densities and a method of determining what range is appropriate for a particular site: 17 BOCC April 18, 2016 DP Determining the density range, High Density range is from 3 du per acre (480 units on the REC parcel) to 1 du per < 2 acres (80 units on the REC parcel), the range for a particular site will be determined by the Planning Commission based on "degree of public benefit" and consideration of such factors as affordable housing, amount of parks/trails/open space, energy conservation, fiscal impacts, preservation of views, providing for schools and other public needs. Growth of New Major Residential Subdivisions There are several major subdivisions (15 units or more) in Garfield County that provide their own internal services (road maintenance, water, sewer) through special districts or HOA. However, these subdivisions are typically far from commercial centers and require travel for even convenience needs which increases traffic and requires higher maintenance of county roads. The Plan recognizes new major subdivisions may occur, but encourages them to be more self- sufficient (having, or being near, convenience services). In order to be more self-sufficient, new major subdivisions will require: i. Safe, reliable access and transit opportunities ii. Construction or upgrade existing offsite connecting county roads and intersections by the developer iii. Review of the fiscal costs vs. fiscal benefits to the public iv. Internal roads to be maintained by a special district or HOA v. Central water and sewer is provided through a special district (quasi -public, not private) vi. Public amenities, such as trails, open areas, parks, etc., that meet the needs of residents are included. Growth in Unincorporated Communities New (or expanded existing) unincorporated communities should meet the following guidelines: i. Not located in UGA of existing municipalities; ii. Served with urban services by a special district; iii. Contract for police from county sheriff is established; iv. Connecting county roads are upgraded at developer's expense; v. Fiscal costs to the public will be considered; vi. Internal commercial is primarily for area residents; vii. Transit opportunities are provided; viii. Recreation and other public amenities are provided; ix. School sites may be required. Chapter 3 -Plan Elements This chapter analyzes plan elements that include: 1. Urban Growth Areas and Intergovernmental Coordination - The nearest property boundary of REC is located 2.46 miles from the Glenwood Springs Urban Growth Area and 2.61 miles from the Carbondale Urban Growth Area, locating this property halfway between two existing population centers. The FLUM designates the property Residential High (1/3 acre to Tess than 2 acres per dwelling unit). 2. Housing - The Applicant proposes to provide 55 affordable units. This maintains the same ratio of 15%. 3. Transportation — The Applicant has stated that this development will provide an opportunity for upper valley employees to live in the Roaring Fork Valley rather than commuting from the Colorado River Valley. In theory this may decrease traffic on 1-70 and Highway 82 through the City of Glenwood Springs. However the location of the development will require that 18 BOCC April 18, 2016 DP residents continue to commute as the site is located between two community centers, transit access will be unavailable and few employment opportunities exist within the development. The improvements required to Highway 82 at the entrance to the site are significant. The Applicant has obtained a new CDOT access permit for the new proposed location. The CDOT access permit requires the Applicant to convert the existing livestock/drainage underpass under Highway 82 to a Bicycle and Pedestrian underpass. Staff understands that the underpass as proposed does not meet CDOT or AASHTO standards. Further, the Applicant is proposing an at -grade crossing of the RFTA Rio Grande Trail, which is not consistent with the previous 2011 approval for a grade -separated crossing. An alteration of the RFTA crossing from grade separated to at -grade will require approval by the RFTA board and the PUC, neither of which has been processed. Per the International Fire Code of 2009, the north parcel and the south parcel each need two vehicle accesses. To accomplish this, the Applicant has proposed on Emergency Vehicle Access (EVA) from the north parcel and one EVA from the south parcel. These EVAs are in addition to the main vehicular access points from Highway 82 on the north parcel and a bridge over Cattle Creek connecting the south parcel to the north parcel. The Applicant is proposing one EVA to the north through H Lazy F Mobile Home Park out to County Road 154 as well as a southern EVA onto Highway 82. An easement is in place through H Lazy F Mobile Home Park for the northern EVA although legal access has not been demonstrated all the way to CR 154, while the Applicant has not yet applied for a CDOT access permit for the southern EVA. The internal road system remains largely unchanged from the 2011 approval. 4. Economics, Employment and Tourism — Though the development and construction will create employment opportunities they will be temporary and will not be primary jobs. Employment for the on-site recreation/daycare/coffee shop facilities may generate several on-going service industry positions. Overall POA maintenance of the development may also create several positions, though a specific number of positions has not been provided. 5. Recreation, Open Space and Trails — The development does provide internal trails and areas for recreation. In addition, as is required by the CDOT access permit for Terrace Parkway, the Applicant is must convert the existing livestock underpass connecting the Rio Grande Trail to the east side County roads for use by bicycles and pedestrians. The Land Use Resolution requires that this facility meet currently accepted design standards. The current livestock underpass should be designed to be safe, accessible and comfortable for users. 6. Agriculture — Limited agriculture may be conducted within the PUD. 7. Water and Sewer Services — The application includes a pre -inclusion agreement with the Roaring Fork Water and Sanitation District (RFWSD). The 2011 application, including the Justification Report, state that the Applicant was considering a community system. 8. Natural Resources — Preservation, protection and enhancement of natural resources is proposed, particularly when the first phase of the development reclaims the site. Protection of the riparian corridor and conservation easement are specifically discussed in the development plan. 9. Mineral Extraction — There are likely significant gravel reserves on the property. The Applicant has determined that this resource will be utilized in the construction of the project to the extent 19 BOCC April 18, 2016 DP that gravel reserves will be stockpiled, crushed on-site and a temporary concrete batch plant will operate to produce construction materials. This use will only occur during construction of the site, however, and will require a separate land use permit. 10. Renewable Energy — Energy and/or water conservation and renewable energy were not included as components of this development. VI. REVIEW STANDARDS & CRITERIA PUD and Zone District Amendment Since this review is for a Substantial Amendment under the 2008 ULUR, this review is focused on the proposed amendments to the approved Preliminary Plan, which became effective on December 19, 2011 became effective on December 22, 2011. Please Note: A summary of the identified issues is provided on Page 50, Section VIII and Development Agreement which SECTION 4-201 REZONING. Rezoning may be initiated by the Board of County Commissioners, the Planning Commission, the Director, or an Applicant for land use change. The rezoning request may be processed concurrently with the land use change application and review process. B. Rezoning Criteria. Unless otherwise provided in these Regulations, an application for rezoning must meet the following criteria. 1. No Spot Zoning. The proposed rezoning would result in a logical and orderly development pattern and would not constitute spot zoning. Staff Comments: The PUD was approved in 2011. The road relocation would result in changes to the PUD in order to accommodate the relocated access point to Highway 82 and the Rio Grande Trail as well as a new bicycle and pedestrian underpass at the Cattle Creek intersection. 2. Change in Area. The area to which the proposed rezoning would apply has changed or is changing to such a degree that it is in the public interest to encourage a new use or density in the area. Staff Comments: The PUD was approved in 2011. While it was determined that this standard was satisfied as part of the original approval to establish the PUD, this application is an amendment to the previously approved zoning and will not result in a significant deviation in the uses or residential densities proposed at that time. 3. Demonstrated Community Need. The proposed rezoning addresses a demonstrated community need with respect to facilities, services or housing. Staff Comments: The PUD was approved in 2011. While it was determined that this standard was satisfied as part of the original approval to establish the PUD, this application is an amendment to the previously approved zoning and will not result in a significant deviation in the uses or residential densities proposed at that time. 4. Compliance with Comprehensive Plan and Intergovernmental Agreements. The proposed rezoning is in compliance with the Comprehensive Plan and any applicable 20 BOCC April 18, 2016 DP intergovernmental agreement affecting land use or development or an amendment to the Comprehensive Plan approved prior to filing a rezoning request. Staff Comments: The PUD was approved in 2011. While it was determined that this standard was satisfied as part of the original approval to establish the PUD, this application is an amendment to the previously approved zoning and will not result in a significant deviation in the uses or residential densities proposed at that time. 5. Original Zone Designation Incorrect. The proposed rezoning addresses errors in the original zone district map. Staff Comments: The Board of County Commissioners approved the current PUD zoning on the site in 2011 which rezoned the parcel from Residential Suburban. This designation was not incorrect and was not in error. 6. Adequate Water Supply. Such an application to rezone a property from one district to another district shall be required to demonstrate the maximum water demand required to serve the most intensive use in the resulting zone district pursuant to Article 7-104 of this Resolution. Staff Comments: The PUD was approved in 2011. While it was determined that this standard was satisfied as part of the original approval to establish the PUD, this application is an amendment to the previously approved zoning and will not result in a significant deviation in the uses or residential densities proposed at that time. The Applicant is proposing to serve the development with water from the Roaring Fork Water and Sanitation District (RFWSD) and has included a pre -inclusion agreement for future connection. In addition, the amendment application was referred to the Colorado Division of Water Resources, which concluded that the "proposed water supply will not cause material injury to decreed water rights so long as the Applicant and District operate the water supply in accordance with the decreed terms and conditions in cases 01 CW 187, 07CW 164 and 08CW198. In addition, so long as the Applicant continues the pre -inclusion agreement with the District that allows for utilization of the District's infrastructure, this office finds that the proposed water supply will be physically adequate." A follow up letter was received from the Division, however, which states that the "Executive Lot" at the far southern end of the development which is not shown to be served by water or sewer lines connected to the RFWSD system, also does not have a permitted water well located on or near the Lot. As a result, while the rest of the development is to be served by the RFWSD for water and wastewater, the "Executive Lot" does not appear to have any source of water or wastewater. 21 BOCC April 18, 2016 DP SECTION 6-202 PUD APPROVAL STANDARDS. Since this review is for a Substantial Amendment under the 2008 ULUR, this review is focused on the proposed amendments to the approved Preliminary Plan, which became effective on December 19, 2011 and Development Agreement which became effective on December 22, 2011. In addition to the standards set forth in Divisions 1, 2 and 3 of Article VII, Standards, the following standards shall apply to PUD applications. A. Compliance with Rezoning Standards. The PUD complies with the approval criteria in Section 4-201(B), Rezoning Criteria. Staff Comments: The PUD was approved in 2011. While it was determined that this standard was satisfied as part of the original approval to establish the PUD, this application is only an amendment to the previously approved zoning and will not result in a significant deviation in the uses or residential densities proposed at that time. Staff comments to the Rezoning Criteria in Section 4-201(B) are outlined above. It is Staff's opinion that the Rezoning Criteria are satisfied. B. Relationship to Surrounding Area. The PUD will not have an adverse impact on the surrounding area. The PUD is compatible with the scale, intensity and type of uses located on adjacent property. Staff Comments: The PUD was approved in 2011. While it was determined that this standard was satisfied as part of the original approval to establish the PUD, this application is only an amendment to the previously approved zoning and will not result in a significant deviation in the uses or residential densities proposed at that time. The proposed amendment will impact surrounding properties by relocating the main access to the development from Highway 82 as well as altering how bicyclists and pedestrians will cross from the Rio Grande Trail to the east side of Highway 82. The relocation of the main access to Highway 82 alters the relationship of the development to the County road network as the previous entrance was across from County Road 113. In addition, because crossing Highway 82 at -grade will become even more perilous for bicyclists and pedestrians as a result of the alterations to the Highway to accommodate vehicular traffic to the development, CDOT has required the Applicant to improve the existing livestock culvert to accommodate non -motorized traffic crossing but have indicated that they will not impose any specific design standard for those upgrades. This crossing is to be located just south of the Cattle Creek intersection. C. Visual Impacts. The layout and design of the PUD shall preserve views and vistas, construction on ridgelines that are visible from major roadways or residential development shall be prohibited, and the design shall be compatible with the surrounding natural environment. Staff Comments: The PUD was approved in 2011. While it was determined that this standard was satisfied as part of the original approval to establish the PUD, this application is an amendment to the previously approved zoning and will not result in a significant deviation in the uses or residential densities proposed at that time. The visual impacts associated with the development will not deviate significantly from those approved in 2011. 22 BOCC April 18, 2016 DP D. Street Circulation System. 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 Comments: The Applicant states the following regarding the street circulation system: The Amendment provides adequate internal street circulation, access for police and fire protection, and for bicycle traffic, as detailed in the Report and the supporting materials in this application. Report, pp. 13-14. The Amendment still has two emergency -only accesses, as requested by the Carbondale and Rural Fire Protection District; one remains in the location provided for in the PUD Plan on the south end of the Property and the other has been relocated to connect to the local street system to the north of the Property. These accesses are designed in compliance with RFTA's emergency vehicle access ("EVA") standards and will be gated and posted to prevent unauthorized users from accessing the EVAs. The only other change in the Amendment is that the relocated access does not have a roundabout like the old access location. The roundabout was not required by the ULUR, and the new design continues to accommodate capacity exceeding 20,000 vehicle trips per day in satisfaction of the ULUR's requirements. As noted, the internal street network is to remain largely unchanged from the 2011 approval. Several items are worth noting, however. - The new Terrace Parkway, while it is proposed to have standard 5 foot pedestrian sidewalks, it is not proposed to have bicycle facilities as required by this Section. The Applicant has requested a waiver from this Standard. - A CDOT Access Permit has not been approved for the southern EVA. According to Dan Roussin, Permit Unit Manager, "With the information provided, it very unlikely CDOT would approve an emergency vehicle access for this development on SH 82." (See CDOT Referral Letter, Exhibit 25) - Per the 2009 International Fire Code, "...Developments of one- or two-family dwellings where the number of dwelling units exceeds 30 shall be provided with separate and approved fire apparatus access roads". The Preliminary Plan approval in 2011 included two EVAs in addition to the main access to Highway 82. From an emergency access standpoint, the development is considered to be divided in two — the north parcel and the south parcel which are separated by Cattle Creek. The two parcels are proposed to be connected by one bridge. The north parcel is proposed to include 167 dwelling units while the south parcel includes 195 dwelling units (362 total). As a result, in order to meet the standards of the IFC for emergency access, the north parcel needs to include a minimum of two access points and the southern parcel needs to include a minimum of two access points. As proposed, the north parcel has emergency vehicle access from the north EVA to County Road 154 and Terrace Parkway to Highway 82, while the southern parcel has proposed emergency access from the south EVA to Highway 82 and the bridge crossing Cattle Creek to the north parcel. 23 BOCC April 18, 2016 DP - The easement provided for the north EVA is unclear and confusing. In addition, the referenced Exhibit C, which was to be a map of the easement area, was never recorded. As a result, it is unclear whether the easement provides legal access from H Lazy F to County Road 154. (See Exhibit 26) - The Applicant has not yet obtained RFTA approval for an at -grade crossing of Terrace Parkway, as proposed. In addition, approval has not been obtained from the Colorado Public Utility Commission (PUC). (See RFTA Referral Letter, Exhibit 14) - Per the CDOT Access Permit for Terrace Parkway, the Applicant is required to convert an existing livestock culvert south of the County Road 113 intersection into a bicycle and pedestrian underpass. This underpass is required because the alterations to Highway 82 will make bicycle and pedestrian crossing even more perilous. - The underpass cannot meet CDOT or AASHTO standards for bicycle and pedestrian underpasses without being enlarged. According to Ken Brubaker, PE of CDOT, "The recommended minimums for a structure such as this in a rural area is 12' of width and 10' of vertical clearance. A structure of this length would ideally be even wider and taller than those required minimums." (See Exhibit 12) In addition, Staff understands that CDOT is relying on the County to impose design standards on this facility will not impose any design standards as a part of their permit on this facility. - The approach to the underpass as proposed does not meet the AASHTO standards for shared -use facilities. The minimum width requirement for a shared use path is 10'. (See Exhibit 12) - The proposed plans do not show a lighting plan. Due to the length of the underpass, it is likely to be dangerous, very uninviting, and claustrophobic without lighting. - CDOT has represented that they will not own or maintain the underpass (See Exhibit 25). In addition, the CDOT Access Permit #313037 requires that the Applicant develop an "agreement between CDOT and the party that will be assuming the ownership and maintenance responsibilities for the structure (Condition 11)." The Applicant has not represented who may own or maintain the underpass. - While west side connections have been represented, the Applicant has not represented how the trail will connect into the County road network on the east side. (See Exhibit 24) - The bridge that crosses Cattle Creek and provides primary vehicular access to the south parcel may require a floodplain permit and/or LOMR from FEMA. (See Exhibit 22) - The island of the round -about eliminates the turning movement into Moraine Court from Riverside Loop Drive. (See Exhibit 22) - The south EVA proposes a grade of 8% which exceeds CDOT standards and may require a revised design. (See Exhibit 22) 24 BOCC April 18, 2016 DP E. Pedestrian Circulation. The PUD shall provide pedestrian ways throughout the PUD that allow residents to walk safely and conveniently among areas of the PUD. Staff Comments: The pedestrian system is adequate for internal pedestrian circulation. Access to the Rio Grande Trail is currently limited to one access point at the existing Cattle Creek intersection along the Cattle Creek drainage, as Staff understands a license agreement for this connection currently exists. Preliminary engineering plans (Item 21 in application) show the extension of the shared -use -path from the culvert under Highway 82 to the RFTA ROW, but do not show details of the connection to the Rio Grande Trail. The Applicant has represented a second access point at Terrace Parkway, however, neither preliminary engineering plans nor legal rights to access to the Rio Grande Trail at this location were submitted. Staff recommends a condition of approval that the Applicant submit a license agreements with RFTA to access the Rio Grande Trail along with preliminary engineer plans for these two locations prior to submittal of the first final plat. F. Open Space. The PUD shall preserve at least twenty-five (25) percent of the area as open space. Staff Comments: Given the site size of 160 -acres the Applicant is required to preserve 74.82 -acres as open space. The Applicant totals the provided open space as follows: Useable Open Space (<25% slope) = Limited Use Open Space (>25% slope) = Recreation Open Space = TOTAL 46.65 -acres 10.84 -acres 17.34 -acres 74.82 -acres or 46.8% The ULUR defines Open Space as "Any land or water area, which serves specific uses of: providing park and recreation opportunities, or conserving natural areas and environmental resources, or structuring urban development form, or protecting areas of agricultural, archaeological or historical significance. Open space shall not be considered synonymous with vacant or unused land or yards as part of a platted lot." Based on this definition the Applicant has provided sufficient open space within the development. G. Housing Variety. The PUD shall provide for variety in housing types, price and ownership forms. Staff Comments: From representations made in 2011, a variety of housing types is provided including garden homes, estates homes and executive homes. Particular units may be attached or detached. Pricing will range from approximately $160,000 to $200,000 for the affordable homes to $1,000,000 for other housing types. Alternate ownership forms include rental of the affordable units, otherwise for -sale deed restricted units or for -sale fair market units are proposed. It is anticipated that 40% of the homes will be under $550,000. No rental housing is proposed within the project. It is likely sales prices will be higher based on current market conditions and the anticipation that the market will continue to increase before development of the site begins. H. Affordable Housing. The PUD shall comply with affordable housing requirements applicable pursuant to Section 8-102 of Article VIII, Affordable Housing. Staff Comments: The Applicant is proposing to maintain the same number and ratio of affordable housing as was approved in 2011. As proposed, the project would include 55 25 BOCC April 18, 2016 DP affordable units which is a ratio of 15% of the total 362 units in the development. Geneva Powell of the Garfield County Housing Authority (GCHA) responded to the application in 2011 which is included with the updated comments from KT Gazunis (EXHIBIT 21). Ms. Gazunis notes in her letter that there is no record of response from the 2011 comments. As a part of Resolution 11-85, the Applicant acknowledges that an Affordable Housing Agreement will be required by the BOCC. As a result, the details of this agreement are to be determined prior to the first final plat. At this time, it will be necessary for the application to respond to the GCHA comments on the REC affordable housing proposal: • The Affordable Housing Plan and Agreement (AHPA) requires presales before building affordable housing unit (AHU). • AHPA provides 3 categories of pricing all of which differ from the GCHA standards (related to percentage of average medium income). GCHA stipulates maximum 120% AMI which Applicant proposed to allow buyers earning up to 150% of AMI — this allows a larger pool of potential buyers. • Applicant proposes an option of renting the AHU if not sold within 120 days. This is not addressed in the County's guidelines. • Questions and comments regarding the proposed agreement includes number of units provided in each phase, amendment of the agreement by phase, etc. The Applicant will need to develop an AHPA in collaboration with the GCHA and consistent with the Land Use Code in place at the time of review or the Code in place at the time of vesting. The AHPA needs to be recorded and executed by both the property owner and the BOCC prior to submittal of the first final plat. 1. Fire Hazards. Fire hazards will not be created or increased; Staff Comments: Fire hazard was addressed as a part of the 2011 approval. Updated comments have been received from the Colorado State Forest Service per wildfire hazard. The Service states that the wildfire hazard in this location is low to moderate. However, the Service has requested that all structures be built to Colorado State Forest Service Defensible Space standards. (See Exhibit 16) J. Recreation Amenities. The PUD shall provide recreational opportunities and amenities to residents of the PUD. Staff Comments: As was reviewed in 2011, significant open space and recreational amenities are planned for the development. REC states that funding for recreation will be collateralized until such time as the residents of the community determine the types of recreation improvements they desire. The Cost Estimate (See Item 18 in application), identified $700,000 for "Park Improvements" which is to be secured at the time of final plat. While the specific location of these facilities has not been identified, the proposed facilities include: multi-purpose lawn areas, multi -use hard surface areas, multi -use soft surface areas, playgrounds/tot lots, picnic / park areas, sidewalks and secondary soft trail connections. In order to determine the form and amount of collateralization, the Applicant needs to provide details on the anticipated location, type and cost of the proposed improvements. Staff recommends that this be added as a condition of approval. 26 BOCC April 18, 2016 DP K. Adequacy of Supporting Materials. The Final PUD Plan meets all planning, engineering, and surveying requirements of these Regulations for maps, data, surveys, analyses, studies, reports, plans, designs, documents, and other supporting materials. Staff Comments: The submitted materials generally satisfy planning, engineering and surveying requirements. Specific deficiencies have been addressed throughout this report and outlined below. L. Taxes. All taxes applicable to the land have been paid, as certified by the County Treasurer's Office. Staff Comments: An updated certificate of taxes has been paid was provided at the time of initial application in 2011. M. Adequate Water Supply. An Adequate Water Supply will be demonstrated in compliance with the standards in Section 7-105. Staff Comments: The Applicant has provided a pre -inclusion agreement with the Roaring Fork Water and Sanitation District (RFWSD) for a legal and physical water supply. The Division of Water Resources has provided comments that the proposed water supply will not cause material injury to other water rights. Regarding the water supply system, the following items are worth noting: - If the Memorandum of Understanding (MOU) is eliminated for the "east side improvements", then the Applicant will be required to obtain applicable permits from Garfield County Road and Bridge as well as CDOT to bring water utilities under the applicable roadways. According to Mountain Cross Engineering, "the application materials seem to provide enough evidence that there is a legal supply of water, however the physical supply is still pending negotiations." As a result, evidence of adequate capacity with the RFWSD system is necessary. (See Exhibit 22) Per the pre -inclusion agreement, Carbondale Investments is not anticipated to make improvements to the water plant. Any necessary improvements, as outlined in the agreement, are required to obtain a Location and Extent review by Garfield County. As proposed, should the Carbondale Investments property be developed in a timely manner, then the following upgrades are outlined in the pre -inclusion agreement: o Ironbridge connection line o State Highway 82 water transmission line o County Road 109 water transmission line o 400,000 gallon buried water storage tank Legal or physical water has not been demonstrated for the southernmost parcel, the "Executive Lot" as water and sewer lines are not proposed to be extended to this parcel. The Division of Water Resources has noted that they have no record of a well permit in or near this location. (See Exhibit 27) - The RFWSD has expressed concern that the property owner may not connect to their system even though RFWSD has committed to serve the development through the pre -inclusion agreement. (See Exhibit 28) Staff recommends a condition of approval 27 BOCC April 18, 2016 DP requiring the development to be connected to the RFWSD system for water and wastewater. VII. REVIEW CRITERIA & STANDARDS Subdivision Preliminary Plan Since this review is for a Substantial Amendment under the 2008 ULUR, this review is focused on the proposed amendments to the approved Preliminary Plan, which became effective on December 19, 2011 and Development Agreement which became effective on December 22, 2011 Subdivision Preliminary Plan Review and submittal requirements include the following sections of the ULUR. The criteria and standards for review are listed in bold italics below, followed by a Staff Response. A. Section 4-502 (C)5. Landscape Plan Landscape plans shall be scaled at 1 inch to 200 feet for properties exceeding 160 acres in size, or 1 inch to 100 feet for properties less than 160 acres in size. Staff Comments: Adequate landscape plans have been provided for the development. B. Section 4-502(D) Land Suitability Analysis 1. Public Access to Site. Show historic public access to or through the site. Staff Comments: Only a very small portion of the property that is not proposed to be developed borders directly on Highway 82. No other portion of the property borders directly to a vehicular roadway. Historically, the property has been accessed via a license agreement with RFTA to access the property by vehicle. Nearly the entire length of the property is adjacent to the RFTA Rio Grande ROW which provides non -motorized access to the property. 2. Access to adjoining Roadways. Identify access to adjoining roads and site distance and intersection constraints. Staff Comments: The primary qualifying roadway adjacent to the property is the RFTA Rio Grande ROW for non -motorized access. REC has very limited access to Highway 82. As a result, a RFTA license and PUC approval are necessary to cross the RFTA ROW, an easement to cross the adjacent GCCI property is required and an access permit from CDOT are necessary to obtain access to Highway 82. The following items have been identified related to legal and physical access: REC has yet to reach an agreement with RFTA for the proposed crossing for Terrace Parkway. This issue has not been resolved and discussions are ongoing. A condition of approval regarding legal and adequate access, including issuance of a RFTA license for an at -grade crossing of the RFTA ROW / Rio Grande Trail and CDOT Notice to Proceed, is recommended by staff (See Exhibit 14). It is worth noting that per the comments received from RFTA, the Applicant currently has approval for a grade -separated trail crossing but does not currently have approval from the RFTA board for an at -grade crossing. In order to ensure legal access across the adjacent property, the Applicant has submitted a draft easement which has not been executed. Staff recommends a condition of approval that the Applicant execute and record the access easement for the main access to Highway 82, known as Terrace Parkway. 28 BOCC April 18, 2016 DP Staff recommends a condition of approval that a public crossing license from the PUC be submitted prior to any activity occurring on the site and prior to submittal of the first final plat application. (See Exhibit 14) 3. Easements. Show all easements defining, limiting or allowing use types and access. Staff Comments: Existing utility easements are clearly identified on the Preliminary Plan, including the existing location and proposed re -location of the Glenwood Ditch, as well as proposed easements that will be required for development of the parcels. Access to the site is shown. However, the proposed 160 -acres does not abut a public road serving vehicles but instead gains access to the state highway system through an agreement with RFTA and an easement across the adjacent property. Colorado PUC approval is required to assure adequate public access to the site. The Roaring Fork Conservancy holds a Conservation Easement on property located west of and central to the development. The Glenwood Ditch traverses this site and current agreements are in place to relocate and pipe the length of ditch through the site. The Applicant also has an easement for the north EVA which crosses property owned by GCCI, H Lazy F Mobile Home Park and several other properties before reaching County Road 154.The easement documentation, which is more fully described in the summary section of this Report, is in need of clarification and correction, however. 4. Topography and Slope. Topography and slope determination. Staff Comments: Analysis has been provided regarding the slope and topography of the site. The property is mostly located on nearly level river terraces approximately 50 to 80 feet above the Roaring Fork River. Steep escarpments (60% slope) separate these terraces. The site has been graded through past development proposals so the natural topography has been modified. The site has undergone extensive grading activity related to prior development of a golf course approved on the property. This grading has resulted in several large soil stockpiles. Mountain Cross Engineering noted that "The project site grading along the north property line shows incomplete contours, trespass on the adjacent property to the north, and creates drainage ponding areas. The Applicant should revise the grading plan and obtain any necessary agreements and/or temporary easements." (See Exhibit 22) 5. Natural Features. Significant natural features on-site and off-site. Staff Comments: Waterbodies on the site include Cattle Creek, the Roaring Fork River is located off-site of the project. The site includes steep escarpments at the western edge of the project adjacent to the RFC easement and the Roaring Fork River. Wetlands are located adjacent to these waterbodies but primarily within the RFC easement with the exception of areas at the southern end of the site and adjacent to Cattle Creek. Few natural features exist on-site due to prior grading and agricultural activities on the site. 29 BOCC April 18, 2016 DP 6. Drainage Features. Existing drainages and impoundments, natural and manmade. Staff Comments: The development parcels have several features that significantly impact drainage: the Roaring Fork River which flows south to north just west of the site boundary and Cattle Creek crosses through the site from east to west dividing the property almost in half. Several comments were received regarding drainage (See Exhibit 22): - Storm drainage culvert labels were not shown on the plat. - The Applicant has not designed the release structures and routing for discharges from the water quality pond. - The storm drainage will need to be revised for the offsite flows flowing from the GCCI parcel into culvert c76 -a. 7. Water. Historic irrigation, tailwater issues, water demands, adequate water supply plan pursuant to Section 7-104. Staff Comments: The Division of Water Resources (DWR) has reviewed the submitted pre - inclusion agreement along with the associated court decrees. As a result, the DWR has determined that the "water supply will not cause materials injury to decreed water rights..." (See Exhibit 23) The physical water supply was originally proposed to be a private system constructed by REC or service from the Roaring Fork Water and Sanitation District (RFWSD). Although the application is not clear whether the development would connect to RFWSD or create a private system, REC and RFWSD have since submitted a pre -inclusion agreement that is a part of the application. Irrigation water was approved as a part of the 2011 approval and is not proposed to be amended. Through the review of this Amended application, it is come to Staff's attention that the proposed Executive Lot at the south end of the development does not appear to be served by the RFWSD water or sewer as the preliminary engineering plans do not show connections to that parcel. Further review of the 2011 application does not show demonstration of legal and adequate water for this parcel. Comments received by the Division of Water Resources indicate that they have no record of a water well in or near the Executive Lot (See Exhibit 27). As a result, Staff recommends a condition of approval that the Applicant provide demonstration of adequate legal and physical water to the Executive Lot. In addition, the Applicant should identify how wastewater for the parcel is to be managed. 8. Floodplain. Flood plain and flood fringe delineations. Staff Comments: A small portion of Cattle Creek floodplain extends into the project area and is generally avoided by development. Encroachments into the floodplain include utilities and bridge structures. The Army Corps of Engineers responded to the referral request (See Exhibit 15) that requires the Applicant to update the wetlands delineation on the property that was last conducted in 2010. The letter from the Army Corps states that "jurisdictional determinations cannot remain valid for an indefinite period of time, therefore this verification is only valid for five years." As a result, the determination issued in 2010 is currently expired. Staff suggests a condition of approval that the Applicant update the wetland determination for the properties as required by the Army Corps of Engineers. 30 BOCC April 18, 2016 DP 9. Soils. Soils determination, percolation constraints, as applicable. Staff Comments: Hepworth-Pawlak Geotechnical, Inc. (HP Geotech) performed an assessment of the soils and geologic conditions of the site, including identification of geologic hazards and soils conditions for the 2011 application. The topsoil was stripped from the site and stockpiled in 2005. Conditions include fill areas that consist of coarse-grained terrace alluvium. The site consists of two post -glacial terraces which are located between five (5) feet and thirteen (13) feet above the Roaring Fork River. The alluvium is described as a deposit of silty sand with occasional boulder, pebble and cobble gravel interbedded and often overlain by sandy silt and silty sand. Shallow groundwater is expected in these areas. Most of the REC project is located on Pinedale outwash terraces occurring in several levels that formed at different periods. The 2005 grading removed all of the mid-level terraces. Soils profiles indicate that these terrace surfaces have been stable with respect to erosion and deposition for over 5,000 years. Stockpiled soil on the site will have to undergo additional analysis/treatment to determine its viability. Rocky Mountain Ecological Services has noted that nutrient levels and microbial populations may result in difficulty reestablishing native vegetation. 10. Hazards. Geologic hazards on-site, and adjacent to site. Staff Comments: HP Geotech conducted a study for the 2011 application which noted the following potential hazards in their assessment: • Evaporite Sinkholes — The Eagle Valley Evaporite formation is located between Carbondale and Glenwood Springs. This formation resulted in regional ground subsidence as a result of dissolution and flowage of evaporite from beneath the region. If still active the likely rate of deformations would occur at a rate of .5 to 1.6 inches per 100 years. • Nine sinkhole areas have been located in and close to REC. Sinkholes in the western Colorado area are typically 10 to 50 -feet in diameter circular depressions. Avoidance of existing sinkholes and appropriate mitigation will address issues associated with these hazards. • Steep Terrace Escarpments — These 60% slope areas vary from 40 to 80 feet high located along the Roaring Fork River and lower Cattle Creek areas. These escarpments are potentially unstable and should be avoided by development. Mitigation methods to stabilize these areas are being considered. • Active Stream Bank Erosion — Erosion along the Roaring Fork and Cattle Creek occurs during high water and contributes to steep terrace escarpment destabilization. Correction of these areas could be beneficial in stabilizing or reducing deformation of the escarpment. • Debris Flow and Floods — HP determined that deposits in these areas do not have a high collapse potential and are moderately compressible indicating that these areas should be avoided or provide adequate mitigation to minimize the hazard. 31 BOCC April 18, 2016 DP HP also reviewed earthquake potential and radiation, neither of which were considered as likely hazards on-site.

Rivr ge 4:0II101Al FIGURE 04 Vegetation p,,, EEpa Ceantle a.apo, (*nr'apary Staff Comments: Natural habitat was reviewed as part of the 2011 application and remains unchanged through this amendment. Vegetative cover is minimal given the agricultural history of the site, as well as the extensive grading activities that took place in 2005. This area is virtually devoid of vegetation except for weeds. Vegetation outside of the graded areas including sage, oak and other brush on the escarpment and cottonwood, grass and willows on the lower terraces. Wildlife habitat areas include both Upland and Riparian Habitat areas with the site consisting largely of Upland Habitat. This area was noted as having limited wildlife use due to vegetation type and cover. It appears that the most common species are ground squirrels, which in turn attract great -horned owls, red-tailed hawk, red and gray fox and coyote. Bird use is limited as well due to conditions and generally includes mourning doves, meadowlarks and mountain bluebirds. The Riparian Habitat occurs along the Roaring Fork and lower Cattle Creek, largely outside of the REC development area. A Great Blue Heron Rookery has historically occurred in this vicinity however one of the original three rookery trees no longer exists due to high springtime flows and bank scour. Analysis of special importance species was contained in the Wildlife & Vegetation Assessment Report. Mule deer, elk, bald eagle, heron and lewis's woodpecker were considered, as well as Ute ladies -tresses orchid which is on the Federally Threatened list. • Elk —The site is located within Elk Winter Range with Severe Winter Range occurring on the east side of SH 82. Elk do use the project area, mainly for `loafing' as foraging opportunities are marginal. The application states that `reasonably high number of elk persist on the project site' however that winter use of the Rio Grande Trail during winter, and construction of wildlife fencing along SH 82 appears to have `noticeably reduced the number of elk observed wintering on the REC property.' 33 BOCC April 18, 2016 DP • Mule Deer — The site is located between Mule Deer Winter Range to the west of the Roaring Fork River and Severe Winter Range on the east side of SH 82. Existing use of the site by mule deer is minimal with the conservation easement area seeing more mule deer activity than the project area. • Great Blue Heron — A productive heron rookery is located in the RFC conservation easement and on the west side of river with a total of 25 nests. A pair of Golden Eagles killed a majority of the young in 2010 and could lead to abandonment in the future. This area is considered critical habitat and is adjacent to the REC project. • Bald Eagle — The closest nest is located in Aspen Glen where nesting has been successful. These birds use the REC site for roosting and hunting. • Lewis's Woodpecker — This migratory bird arrives in May and departs in early to mid- September utilizing the habitat adjacent to the project area. This bird is considered a `sensitive species' by the USFS. 12. Resource Areas. Protected or Registered Archaeological, cultural, palentological and historic resource areas. Staff Comments: No recorded sites of archeological or historic importance were found to exist in the project area. C. Section 4-502(E) Impact Analysis 1. Adjacent Property. An address list of real property adjacent to the subject property, and the mailing address for each of the property owners. Staff Comments: Adequate information has been provided. 2. Adjacent Land Use. Existing use of adjacent property and neighboring properties within 1500' radius. RiTer-Edge F JGURE 03 Pco).ctfxe Far - 34 BOCC April 18, 2016 DP Adjacent land uses were reviewed as a part of the 2011 application. No notable changes have occurred in the area since the previous approval. Staff Comments: Adjacent land use includes: • North — uses include commercial, semi -industrial and mobile home park • South — Aspen Glen PUD (residential and recreation) and LaFarge Gravel Pit • East — State Highway, RFTA RaiI/Trail, commercial and semi -industrial uses • West — Ironbridge PUD and Teller Springs 3. Site Features. A description of site features such as streams, areas subject to flooding, lakes, high ground water areas, topography, vegetative cover, climatology, and other features that may aid in the evaluation of the proposed development. Staff Comments: Site features were reviewed as part of the 2011 application and have not changed since that time. Site features include Cattle Creek and associated wetlands, steep slopes and little vegetative cover. Features adjacent to the project area include the Roaring Fork River and associated wetlands, heron rookery, and the Roaring Fork Conservancy Easement. These features have been used to determine a layout for the development of REC which is clustered to minimize impact. Mitigation measures include avoidance to the extent possible of these sensitive environments and open space placement to provide buffers. 4. Soil Characteristics. A description of soil characteristics of the site which have a significant influence on the proposed use of the land. Staff Comments: Soil characteristics were reviewed as part of the 2011 application and have not changed significantly since that time. The Applicant stated that "this analysis has determined that there are no adverse impacts associated with soils and surficial deposits provided common construction and site evaluation techniques are implemented as detailed in the Hazard Mitigation Plan and that reclamation and erosion control... and Erosion and Sediment Control Plan are provided" (Page 66 of impact analysis). This section of the 2011 application goes on to state that potential impacts and mitigation measures are identified as a series of standard considerations with respect to construction on soils of this type and further, that these require engineering assessment and design activities including boring, testing, and onsite review during development. In 2011, HP Geotech noted that shallow foundations placed on the upper natural soils should typically be suitable for structure support. Relatively rigid foundations such as heavily reinforced slabs could be used to reduce the risk of differential settlement and building stress, where determined necessary. The 2011 application goes on to state that slab -on -grade construction should be feasible for bearing on the natural soils or compacted structural fill, but that there could be some potential for post -construction slab movement at sites with collapsible soils or expansive clays. Removal of the moisture sensitive soils and replacement with compacted structural fill could be provided to reduce the risk of movement. 35 BOCC April 18, 2016 DP A detailed pavement design was proposed to be provided post -reclamation to determine if fine-grained soils exist that need to be removed. In 2011, additional geotechnical analysis was to be required to determine if previous fill material placed on the site is suitable for building foundations. This analysis is to occur post reclamation therefore a condition of approval that requires the additional analysis be provided at final plat should be sufficient. 5. Geology and Hazard. A description of the geologic characteristics of the area including any potential natural or man-made hazards, and a determination of what effect such factors would have on the proposed use of the land. Staff Comments: Geology and hazards were reviewed as part of the 2011 application and have not changed significantly since that time. A Hazard Mitigation Plan was submitted in 2011 which addresses potential natural and man-made hazards. Conditions at that time and proposed conditions include analysis of: • Geologic Hazards — Evaporite Sink Holes, Steep Terrace Escarpments, Active Stream Bank Erosion, and Debris Flow/Floods. • Other Hazards — Floodplain, Wildfire These hazards could cause potential impacts to site grading, infrastructure (including roads and utilities) as well as foundation design. Proposed mitigation includes identification of specific areas of concern that may require further review: • Three zones of varying degree of impact from sink holes were assigned to the project area. o Zone 1 represents an 80 -foot buffer area around existing or observed sinkholes where the risk of new or reactivating sinkholes is high. This area is generally avoided however a few roads and utilities are planned within this zone. Potential mitigation measures including grouting or structural bridging; o Zone 2 is a risk area that indicates the presence of sinkholes but no evidence of sinkholes have been identified. Additional geotechnical analysis should be completed prior to final plat so that design of buildings and facilities provide appropriate mitigation; o Zone 3 is the remainder of the property which has a low potential for new sinkhole development however HP recommends that assessment and investigation be completed during grading and building site development. • Steep Terrace Escarpments, Active Stream Bank Erosion, Debris Flows and Floods and Earthquakes are avoided or mitigated thus resulting in no adverse impacts. 36 :ajgec't race Cncranc BOCC April 18, 2016 DP nlo‘orl r daunt 1/r, .10049 Oo fa, ro, so, 'r i nt .a w.rd Fnre, • 4.1 farscatEslorsao (71.. s o,....

Evaluation of the effect of the proposed land use on the capacity of the source of water supply to meet existing and future domestic and agricultural requirements and meeting the adequate water supply requirements of Section 7-104. Staff Comments: This development is subject to Section 7-105 due to the water demand in an amount greater than eight (8) single family equivalents (where an SFE is determined to be 350 gallon of water per day). The 2011 application discussed the `potential' physical supply as being provided by the Roaring Fork Water and Sanitation District (RFWSD) or by a private water system within the REC development. As a part of this amended application, the Applicant has submitted a pre -inclusion agreement with RFWSD. In addition, the Division of Water Resources (DWR) has reviewed the submitted pre -inclusion agreement along with the associated court decrees. As a result, the DWR has determined that the "water supply will not cause materials injury to decreed water rights..." (See Exhibit 23) Irrigation water is planned to be provided via a raw water system utilizing water rights from the Glenwood and Station Ditches. The proposed Executive Lot does not appear to be served by the RFWSD water or sewer as the preliminary engineering plans do not show connections to that parcel. Further review of the 2011 application does not show demonstration of legal and adequate water for this parcel. As a result, Staff recommends a condition of approval that the Applicant provide demonstration of adequate legal and physical water to the Executive Lot. In addition, the Applicant should identify how wastewater for the parcel is to be managed. 37 BOCC April 18, 2016 DP 7. Effect on Groundwater and Aquifer Recharge Areas. Evaluation of the relationship of the subject parcel to floodplains, the nature of soils and subsoils and their ability to adequately support waste disposal, the slope of the land, the effect of sewage effluents, and the pollution of surface runoff, stream flow and groundwater. Staff Comments: In the 2011 application HP Geotech provided analysis of the groundwater which is generally deep in the Eagle Valley Evaporite deposits and that 'free water was not encountered in the relatively shallow borings of depths between 39 and 77 feet. Shallow groundwater may be likely in the river terraces outside of the REC development." Surface run-off will be collected and concentrate to surface drainage systems where the flow will be discharged through lined surface ditches and pipes to lined water quality detention facilities. This system is designed to ensure that water is treated prior to delivery to receiving streams. In 2011, Chris Hale of Mountain Cross Engineering, stated that this is sufficient and that standard on-site detention to limit flow is not necessary due to the location of the site. In Mr. Hale's review of the amended application, he noted that the "Applicant should design the release structures and routing for discharges from the water quality ponds." (See Exhibit 22) Staff recommends a condition of approval that the Applicant provide a design of the water quality pond discharges to be reviewed by the County engineer prior to final plat. 8. Environmental Effects. Determination of the existing environmental conditions on the parcel to be developed and the effects of development on those conditions, including: a. Determination of the long term and short term effect on flora and fauna. b. Determination of the effect on significant archaeological, cultural, palentological, historic resources. c. Determination of the effect on designated environmental resources, including critical wildlife habitat. (1) Impacts on wildlife and domestic animals through creation of hazardous attractions, alteration of existing native vegetation, blockade of migration routes, use patterns or other disruptions. d. Evaluation of any potential radiation hazard that may have been identified by the State or County Health Departments. e. Spill Prevention Control and Counter Measures plan, if applicable. Staff Comments: The Applicant provided a response to these standards in 2011 and those were reviewed at that time. a. Effect on flora and fauna — Rocky Mountain Ecological Services prepared a Wildlife and Vegetation Report in 2011 which analyzed the potential impacts of the development proposal on plants and animals. At that time, the Colorado Division of Wildlife (CDOW / CPW) had responded to the referral that there should not be significant impact if recommendations are followed. CDOW / CPW recommendations included fencing, adequate setbacks from sensitive areas and protection of the heron rookery. 38 BOCC April 18, 2016 DP b. No significant archaeological or historic resources were identified that would be adversely effected. c. Effect on environmental resources, including wildlife and domestic animal control — the development plan in 2011 included protective measures related to wildlife including timing restrictions for construction activity and inclusion of domestic animal controls in the CCR's. d. Radiation hazard — There is low potential for radiation hazard at this site. e. Spill Prevention Control and Counter Measures plan is an Environmental Protection Agency (EPA) requirement that is applicable to facilities that meet criteria such as having above ground storage capacity of greater than 1,320 gallons, and that a project will discharge into or upon navigable waters of the United States. It was assumed that an SPCC plan is to be required related to infrastructure construction and gravel crushing/processing. 9. Traffic. Assessment of traffic impacts based upon a traffic study prepared in compliance with Section 4-502(J). Staff Comments: A Traffic Assessment has been provided by HDR which was conducted in December 2013. This Traffic Assessment is for the new access location as proposed in this amended application and it is understood that the Applicant used this traffic assessment to obtain the new CDOT access permit (#313037). A Notice to Proceed has not yet been issued by CDOT, however. The Assessment states the following: Through continuing "coordinated planning and design discussions" the Developer and County Public Works and Facilities subsequently identified and agreed upon a revised preliminary design concept for access to the Developer's property whereby split Continuous Green T -Intersections, located approximately 0.5 miles apart, will provide separate West Intersection and East Intersection access. This agreed upon access configuration was presented in the revised Traffic Operations/Access Assessment for the Cattle Creek Metropolitan District (Traffic Report, June 2013) and was used as the basis of future build conditions analysis. This concept, the consensus preferred alternative by the Developer, the County and CDOT, also includes closure of the existing west side access at Cattle Creek Road, closure of three existing accesses that serve the former Sopris' Restaurant parcel, and improvement of the existing livestock underpass at Cattle Creek Road to provide a pedestrian/bicycle crossing. Continuous Green T (CGT) Intersections are configured to isolate one of the two mainline approaches to continuously bypass the signal, significantly improving intersection performance. For the offset, paired T - intersections at Cattle Creek Road and the New Access, one intersection would isolate, and allow continuous flow of the southbound lanes, and the other intersection would isolate, and allow continuous flow of the northbound lanes. This will have the effect of minimizing the impact of the signalized accesses on SH 82 traffic flow in both directions, and would have significantly less impact than the pair of signalized full -movement and three quarter movement intersections that would otherwise be required to serve the Project Site. 39 STANDARD VERSION CONTIN UOU S GREEN VERSION BOCC April 18, 2016 DP An assessment of the existing stock under pass/drainage culvert was completed. Based on the findings, it was determined that necessary modifications can be made to utilize the existing under pass as a pedestrian/bicycle crossing. Bicycle/pedestrian tracks observed on the bottom of the existing under pass indicate that the structure is currently being used for the purpose of crossing SH 82. Based on the amount of pedestrian/bicyclists crossing at this location the structure would be sufficient and would provide a safe crossing alternative to that of an at - grade crossing. The current structure, 6 feet wide by 7 feet tall, would need the following modifications to improve function as a bicycle/pedestrian crossing: o Extension of the structure on both ends as required by roadway widening for intersection improvements o Addition of a top slab in the existing SH 82 median o Addressing drainage thru the structure, possibly by the addition of a culvert to accommodate surface runoff and keep sedimentation and debris from accumulating in the crossing. The proposed conversion of the bicycle/pedestrian underpass was reviewed by both the CDOT Bicycle and Pedestrian Facility Engineer, CDOT Permit Unit Manager, SGM, Inc., and Mountain Cross Engineering. While the Applicant's engineer, HDR, has indicated that "an assessment of the existing stock under pass/drainage culvert was completed," a copy of that assessment was not provided in the application. Based on the recommendations from the Applicants engineer, Garfield County Road and Bridge and Engineering (Exhibit 24 and Exhibit 17), CDOT (Exhibit 12 and Exhibit 25), SGM, Inc. (Exhibit 13) and Mountain 40 BOCC April 18, 2016 DP Cross Engineering (Exhibit 22), the following is a summary of the comments and suggestions: The conversion of the current livestock culvert to a bicycle/pedestrian underpass is critical to the proposed access to the CI property. The total length of the underpass is to be approximately 150 feet and as a result, if it is not designed and built properly, it could be perceived as unsafe and uncomfortable for users. The proposed design does not meet AASHTO or CDOT standards. Staff understands that CDOT will not implement design standards for this facility and is relying on Garfield County to implement design standards to make it functional. o The current culvert is 6 feet wide by 7 feet high. o The recommended minimums for the structure is 12 feet wide (CDOT and AASHTO) and 10 feet high (CDOT and AASHTO), but ideally wider and taller. o The minimum recommended width for the shared -use -path is 10 feet (CDOT and AASHTO). - No lighting plan was proposed. Lighting is recommended due to the length of the culvert. - The current opening that provides light from the median will be filled in, providing less Tight then currently enters the culvert. Drainage through the culvert needs to be accommodated separate from the shared - use -path through the facility. - Details need to be provided showing how west extension will be connected to the culvert. Details need to be provided showing how the trail will connect to the County road network on the east side. The Applicant needs to represent who will own and maintain the facility. Details regarding waterproofing need to be provided. - Details of the shared -use -path surface through the facility need to be provided. - Snow fencing should be considered behind the guardrails to prevent trail users and the trail from being covered by snow thrown from the Highway. - More detail is necessary to determine if the proposed design would meet ADA standards as required by CDOT. 41 BOCC April 18, 2016 DP Photos of Existing Culvert to be Converted to Bicycle / Pedestrian Underpass 10. Nuisance. Impacts on adjacent land from generation of vapor, dust, smoke, noise, glare or vibration, or other emanations. Staff Comments: As noted in 2011, nuisance impacts will likely occur during the reclamation and construction phases of the development. This activity will generate dust, smoke, noise, glare, and potentially vibrations, particularly during reclamation and construction, as well as related to mineral `material processing' activities. The proposed PUD Guide contains Article IV, Development Standards, which includes Section C. Specific Use, Facility and Activity Standards. This includes noise standards based upon statutory requirements and section standards related to utility facilities. This latter section includes requirements for noise levels, vibration, smoke, odor and air quality. These standards should be applicable to the whole development, particularly during construction activities. 11. Reclamation Plan. A reclamation plan consistent with the standards in Section 7- 212. Staff Comments: The Reclamation Plan was reviewed in 2011. The Applicant submitted two sets of requirements related to reclamation activities, pre -development reclamation and post -development reclamation. Pre -Development Reclamation — The current site condition exists due to past grading activity on the site related to prior development plans that included construction of a golf course. The pre -development reclamation activity is specific to repairing the damage that past grading created, including restorative and pre -development actions: • Relocation and grade separation of the Rio Grande Trail; 42 BOCC April 18, 2016 DP • Relocation of the Glenwood Ditch; • Re -grading of the site for proper drainage, resolve existing and potential geotechnical hazards, prepare developable areas, restore grade -breaks, replace topsoil, repair and stabilize eroding steep terrace escarpments and repairing active stream bank erosion; • Construction of drainage facilities and water quality detention ponds; • Revegetation of open space area. Post -Development Reclamation — This requirement is included in the PUD Guide development standards and is consistent with the standards in Section 7-212. D. Section 7-100 GENERAL APPROVAL STANDARDS FOR LAND USE CHANGE PERMITS 1. Section 7-101 Compliance with Zone District Use Restrictions Staff Comments: The uses remain unchanged with this amended application. Generally, the PUD zoning allows for variation from standard zone districts, however the proposed uses must be consistent with uses in the underlying zone district or compatible/conforming to Comprehensive Plan goals. 2. Section 7-102 Compliance with Comprehensive Plan and Intergovernmental Agreements Staff Comments: Compliance with the Comprehensive Plan and Intergovernmental Agreements was generally determined with the original application in 2011. 3. Section 7-103 Compatibility Staff Comment: Compatibility of the development was determined at the time of original application in 2011. This standard requires that the nature, scale and intensity of the proposed use be compatible with adjacent land uses and that the use will not result in adverse impact to adjacent land. Adjacent land uses includes high-density mobile home parks, commercial and semi -industrial uses, a gravel pit, and residential communities. The combination of uses proposed in REC may be more intense than adjacent uses which appear as more single use type projects. 4. Section 7-104 Sufficient Legal and Physical Source of Water Staff Comments: This section does not apply to this proposal as water demand exceeds eight (8) single family equivalents (SFE's). See Section 7-105. 5. Section 7-105 Adequate Water Supply Staff Comments: The Applicant has provided a sufficient legal and physical source of water to serve the proposed development of 362 SFE's. The Division of Water Resources has provided a letter stating that there will be no material injury to other water rights as a result of the development. In addition, the Applicant has provided a pre -inclusion agreement with the Roaring Fork Water and Sanitation District for water service. The Executive Lot is currently not connected to the internal water supply system from RFWSD. If the Applicant wishes to connect this parcel to the RFWSD system, the 43 BOCC April 18, 2016 DP preliminary engineering plans need to be modified showing this connection. As an alternative, the Applicant needs to demonstrate adequate and legal water supply for this parcel. 6. Section 7-106 Adequate Water Distribution and Wastewater Systems Staff Comments: A pre -inclusion agreement with the Roaring Fork Water and Sanitation District to provide water/wastewater services has been provided. This pre -inclusion agreement outlines the process for water line extensions and facility upgrades. It is worth noting that certain facility upgrades will require a Location and Extent review through Garfield County, through an application to be filed by RFWSD. The current preliminary engineering plans do not show water or wastewater lines running to the Executive Lot. Should the Applicant wish to connect this Lot to the RFWSD system, then the preliminary engineering plans need to be modified to show this connection. As an alternative, the Applicant needs to demonstrate adequate and legal water and wastewater service for this Lot. 7. Section 7-107 Adequate Public Utilities Staff Comments: It appears that adequate public utilities are available to serve the proposed development. 8. Section 7-108 Access and Roadways Staff Comments: Please see previous discussions regarding access to the site. Regarding safe access, and as a result of the reviews from CDOT, SGM, Inc. and Mountain Cross Engineering, it is clear that the proposed design for the bicycle and pedestrian underpass does not meet State (CDOT) or Nationally (AASHTO) recognized standards for this kind of facility as is required by this Section and therefore, cannot be considered safe as proposed. Generally, the internal road network was reviewed and approved in 2011. Some modifications to the internal road network have generated some comments, however. - An engineered pavement design should be submitted based on the project specific soils. - The traffic calming island of the round -about eliminates the turning movement into Moraine Court from Trailside Drive. 9. Section 7-109 No Significant Risk from Natural Hazards Staff Comments: Natural Hazards were reviewed as part of the 2011 approval. In 2011, it was noted that natural hazards exist on the site which includes steep slopes, slope stability issues, soils, sinkholes and other geotechnical issues. The proposed development generally avoids the hazard areas and/or provides adequate mitigation measures. 44 BOCC April 18, 2016 DP E. Section 7-200 GENERAL RESOURCE PROTECTION STANDARDS FOR LAND USE CHANGE PERMITS 1. Section 7-201 Protection of Agricultural Lands Staff Comment: The application in 2011 noted that this standard is not applicable as agricultural activities have not occurred on this site for many years. The Glenwood Ditch traverses this property and an agreement exists regarding location and piping of the ditch. On-site irrigation is proposed to use raw -water with rights from both the Glenwood Ditch and the Station Ditch. 2. Section 7-202 Protection of Wildlife Habitat Areas Staff Comment: The application in 2011 noted that wildlife habitat areas include a heron rookery and use of the site by both mule deer and elk. 3. Section 7-203 Protection of Wetlands and Waterbodies Staff Comment: The application in 2011 noted that Section 7-203 determines that an `Inner Buffer Zone' requires provision of a thirty-five (35) foot setback from the high water mark on each side of a waterbody. Removal of live vegetation or placement of any material within this zone is prohibited except for irrigation and water diversion facilities, culverts, bridges and other reasonable and necessary structures requiring some disturbance within this setback may be permitted. Staff recommends a condition of approval identifying this setback. Please see the previous discussion regarding delineation of the wetlands as required by the Army Corps of Engineers (See Exhibit 15). 4. Section 7-204 Protection of Water Quality from Pollutants Staff Comment: The application in 2011 noted that activities that will require storage of material, equipment or fluids should be located to protect waterbodies. This standard includes a requirement for spill prevention, maintenance of equipment and machines, location of fuel storage areas and collection and temporary storage areas. A Spill Prevention Control and Countermeasures plan may be required and the stormwater management plan should address this issue. 5. Section 7-205 Erosion and Sedimentation Staff Comments: The application in 2011 noted that this section applies to land disturbances of greater than one-half (1/2) acre. The Applicant submitted an Erosion and Sediment Control Plan that addresses stabilization of slope stability and stream bank erosion. Vegetative cover on the site will provide additional erosion and sedimentation protections. The steep slope areas are avoided by the development. 45 BOCC April 18, 2016 DP 6. Section 7-206 Drainage Staff Comments: Please see previous discussions regarding access to the site. The major aspects of the drainage plan was reviewed as a part of the 2011 application. 7. Section 7-207 Stormwater Run -Off Staff Comments: The application in 2011 noted that this section applies to new development within 100 feet of a waterbody and to development creating 10,000 square feet or more of impervious surface. The REC development meets these criteria and therefore has proposed plans to create water quality detention areas prior to discharge of stormwater to the Roaring Fork River. There is no plan for standard on-site detention of stormwater except for storage areas that would be required for assuring water quality prior to discharge. This code section also includes requirements for on-site detention designed to detain flow to historic peak discharge rates and provide water quality benefits. This section was reviewed as a part of the application in 2011. As noted previously, the Garfield County contract engineer generated several comments from the proposed amendments, including (See Exhibit 22): - Storm drainage culvert labels were not shown on the plat. - The Applicant has not designed the release structures and routing for discharges from the water quality pond. - The storm drainage will need to be revised for the offsite flows flowing from the GCCI parcel into culvert c76 -a. According to Mountain Cross Engineering, "There are a series of three culverts that collect water from the GCCI property and discharges it onto the REC property. There is a proposed culvert that shows an area inlet near but not inline (hydraulically speaking) with these existing culverts. No grading is shown to connect the proposed to the existing. Also, the inlet is shown as a surface, drop type inlet versus an end section inlet; so it may not effectively capture the offsite flows (depending on the magnitude of the event). Downstream from this are proposed lots that could be potentially flooded if this exchange of flows from existing culverts to proposed isn't adequately captured." 8. Section 7-208 Air Quality Staff Comments: Air quality was reviewed as a part of the 2011 application. At that time, it was noted that air quality shall not be impacted by the land use. No response was received from CDPHE in 2011. Other air quality impacts may result from the crushing of aggregate and batch plant operations that are proposed as temporary construction -related activities. 9. Section 7-209 Areas Subject to Wildfire Hazards Staff Comments: This site is located in a low to moderate wildfire zone. 46 BOCC April 18, 2016 DP 10. Section 7-210 Areas Subject to Natural Hazards and Geologic Hazards Staff Comments: Natural and Geologic Hazards were reviewed as a part of the 2011 application, which noted that such hazards do exist on the site however it appears that the development plan avoids many of the hazard areas and provides mitigation measures where avoidance is not possible. 11. Section 7-211 Areas with Archeological, Paleontological or Historical Importance Staff Comments: As reviewed in the 2011 application, no areas exist on the site within these categories. 12. Section 7-212 Reclamation Staff Comments: Initial reclamation of the site was reviewed as a part of the initial application in 2011. At that time, it was noted that the REC development proposal contains a substantial pre -development reclamation plan to repair and restore slope and stream bank issues as well as grading and topsoil issues related to prior grading of the site. This reclamation will also allow for additional geologic investigation as well as to prepare the site for eventual development. F. SECTION 7- 300 SITE PLANNING AND DEVELOPMENT STANDARDS 1. Section 7-301 Compatible Design Staff Comments: Initial reclamation of the site was reviewed as a part of the original application in 2011. At that time, it was noted that compatible design encompasses issues regarding site organization as well as operational characteristics, lighting, buffering, materials, and building scale. Certainly the density, site organization and buffering can be evaluated for compatibility with adjacent subdivisions such as Ironbridge and Aspen Glen. The clustering of the dwellings into several pods leaves tracts of open space to buffer the site both physically and visually. Much of the development occurs on an interim bench west of the Rio Grande Trail with proposed landscaping providing additional buffers from adjacent developments. For comparison, Aspen Glen, Iron Bridge and the amended REC developments are listed below. Aspen Glen — 1.13 acres / dwelling unit (938.4 acres with 830 dwelling units) Iron Bridge — 1.83 acres / dwelling unit (533.5 acres with 292 dwelling units) REC — 0.44 acres / dwelling unit (160 acres with 362 dwelling units) 2. Section 7-302 Building Design Staff Comments: Not applicable. 3. Section 7-303 Design and Scale of Development Staff Comments: This Standard was reviewed as a part of the original approval in 2011. 4. Section 7-304 Off-street parking and Loading Standards Staff Comments: This Standard was reviewed as a part of the original approval in 2011. 47 BOCC April 18, 2016 DP 5. Section 7-305 Landscaping and Lighting Standards Staff Comments: This Standard was reviewed as a part of the original approval in 2011. 6. Section 7-306 Snow Storage Standards Staff Comments: This Standard was reviewed as a part of the original approval in 2011. 7. Section 7-307 Roadway Standards Staff Comments: This Standard was reviewed as a part of the original approval in 2011. The Applicant has provided road profiles for the new Terrace Parkway and north and south EVAs. It appears that this roadway meet the applicable standards. Please see previous discussions for more detail on other aspects of the road network. 8. Section 7-308 Trail and Walkway Standards Staff Comments: Please see previous discussions for regarding trails and walkways. 9. Section 7-309 Utility Standards Staff Comments: The REC development is proposing to install underground utilities that will be further reviewed at final plat for sufficiency of design and provision of adequate utilities. G. SECTION 7- 400 SUBDIVISION STANDARDS AND DESIGN SPECIFICATIONS 1. Section 7-401General Subdivision Standards Staff Comments: These standards include preservation of natural features, extensions for future development, maintenance of common facilities, domestic animal control and fireplace restrictions. One issue occurs regarding maintenance of common facilities with this amendment, notably maintenance responsibility of the bicycle and pedestrian underpass. According to the CDOT Access Permit, Condition #11, the Applicant is required to "provide a copy of the signed agreement between CDOT and the party that will be assuming the ownership and maintenance responsibilities for the structure (bicycle and pedestrian underpass)." Since Garfield County does not have a department that could assume this responsibility, the Applicant will need to identify another entity to maintain the facility, which would presumably be the Cattle Creek Metro District. In addition, Section 7-401(C) requires that "Maintenance of common facilities must be accomplished either through covenants and a homeowners association, a separate maintenance agreement, or some other perpetual agreement." In order to meet this Standard and the CDOT Access Permit, Staff recommends a condition of approval that the Applicant identify an entity to assume maintenance responsibility for the facility and execute an agreement between the entity and CDOT prior to the first final plat. 48 BOCC April 18, 2016 DP 2. Section 7-402 Subdivision Lots Staff Comments: This standard was reviewed in 2011 and verified through the amended application. All Tots within the subdivision appear to be configured in a proper mariner with adequate lot sizes and access. 3. Section 7-403 Fire Protection Staff Comments: The site is located within the Carbondale & Rural Fire Protection District and a fire station is located on the north end of the H Lazy F Mobile Home site west of the intersection of CR 154 / SH 82 and CR 114. Please see the previous discussions regarding the proposed EVA accesses. As was noted in 2011 and required as a part of the approval, the Applicant is required to pay an impact fee in the amount of $730/unit resulting in a fee of $264,260.00 which will be due at final plat. The amended application was reviewed by the Carbondale Fire Protection District who noted that "the proposed water system and fire hydrant locations are acceptable" (See Exhibit 19). Mountain Cross Engineering also provided comments regarding the fire protection system proposed to serve the development. Specifically, that "miscellaneous fire hydrants are shown throughout the development without any connection shown to the proposed water lines" (See Exhibit 22). Staff suggests a condition of approval requiring the Applicant to address this issue. 4. Section 7-404 Survey Monuments Staff Comments: This requirement will be met. 5. Section 7-405 Standards for Public Sites and Open Space Staff Comments: As a part of the 2011 application, the Applicant proposed payment of fee in -lieu of school land dedication. As a condition of approval in 2011, the Applicant is required to pay a fee in -lieu fee to the school district. Please see previous discussions regarding open space size and use. The open space plan was reviewed by the Garfield County Vegetation Manager who had the following comment: The Open Space and Management Plan (OSMP), Item 5 states that "weeds that occupy 5% of the foliar cover shall be treated in accordance with the State Noxious Weed Act." As a 5% cover is not acceptable, Staff recommends a condition of approval requiring that this section be deleted. 6. Section 7-406 Standards for Traffic Impact Fees Staff Comments: The site is not located within a Traffic Impact Fee zone. 49
