Comments and recommendations from that letter are still relevant. The Cattle Creek development property is not located within any mapped big game critical habitat areas, but is adjacent to important elk and deer winter range on the east side of Highway 82. Use by deer and elk on the property generally occurs during the winter and spring months with some year round deer use on the riparian corridors along the Roaring Fork River and Cattle Creek. While it is not mapped critical winter range the property has become a preferred wintering area for elk. The upper benches provide loafing/solitude areas, while the riparian corridors provide cover and food. A mapped elk highway crossing exists to the south of the property and a wide mule deer crossing runs along most of the eastern boundary of the property. Car/elk accidents have increased significantly along the stretch of SH 82 from mile marker 6.5-12 in the past several years. In addition the property is home to a large great blue heron colony , many small mammals, neo -tropical song birds, raptors and amphibians. The overall size and density of this project is going to have direct and indirect impacts to wildlife. Until a final site plan is implemented not all impacts to wildlife can be addressed. The Division is concerned about several issues related to the current development proposal and makes the following recommendations: 1. The proposed trails into the riparian areas along Cattle Creek and the Roaring Fork River should be eliminated. Any recreational trails proposed should remain on the bench above the river and out of the conservation easement areas held by the Roaring Fork Conservancy. The proposed trails are listed for fisherman access but in reality these will become recreational hiking trails and dog walking areas which will rapidly diminish the values for wildlife that the easements are designed to protect. DEPARTMENT OF NATURAL RESOURCES, Hams D. Sherman, Executive Director WILDLIFE COMMISSION. Robert Bray. Chair • Brad Coors. /ice Chair • Tim Glenn. Secretary 2. The Division is discouraged with the fact that the current great blue heron nesting locations have not been identified in the current building plan nor have any steps been taken to minimize impacts in the building plan. The mitigation proposals outlined in the CCR's are inadequate and rely on future abandonment of the colony. The current locations are several hundred yards upstream of the old nest sites identified in the building plan and have been active for over 5 years. The heronries located on the south west portion of the property are likely to be greatly impacted with the current development plan. Nests are located as close as 27 yards to the crest of the hill directly east of the heronry. The building sites proposed for this area are well within the standard DOW recommended buffer of 1640 ft. and will likely cause abandonment of the heronry. Substantial measures are needed to minimize the impacts this development will have on the heronry including: creating a 200 meter buffer zone around the heronry with extensive berming and vegetative screening, restrictions on construction timing, and limiting of upper level decks on homes facing the heronry. All berming and vegetative screening should be in place at least 1 year prior to any construction occurring within 400 meters of the heronry. More detailed recommendations can be given when a detailed construction plan is submitted. 3. 100' building envelope set backs need to established from the crest of the bluff overlooking the riparian corridors on the Roaring Fork River and Cattle Creek. 4. Maximum building height should be 25' especially for building locations overlooking the Roaring Fork River and Cattle Creek. 5. The DOW would like to sit down with the developer to further discuss their proposal for funding off-site mitigation and habitat enhancement. Thank you for the opportunity to comment.

Eastley Cc: Babler, Alisa; Yeates, Sean Subject: Cattle Creek Colorado PUD Attachments: TIA Coord Process 090126.doc; TIS Outlines.pdf Kathy- Thank you for the opportunity to review the Cattle Creek Colorado PUD on SH 82. This development is a big development and has a considerable impact to CR 113. I have done a curtsey review the of the Traffic Impact Study dated October 17, 2008 by 8140 Partners LLC. This project will need to have an access permit for CR 113 and for the proposed right-in/right out access near Marland Road. However, at this point, CDOT does not support the right- in/right-out access. The applicant will need to provide proof that access cannot be obtain from CR 113. The original proposal did have a full movement that would be shared access with the property to the north with an additional access closure. This will need to be reviewed by the Department. The traffic study doesn't meet CDOT standards. The engineer did not get with CDOT to go over the methodology of the traffic study. CDOT did not have any input in the traffic study and at this point, we don't agree with the methodology of the report. Here is a copy of our standards for Traffic Studies. The study didn't look at 20 year horizon; it look until 2020 (12 years). The study didn't recommend any auxiliary lanes on the highway even when warranted by the State Highway Access Code. The study didn't take in consideration of the north side of CR 113. How will the signal operate with a 5 legged intersection (CR 109, CR 113, 2 Frontage Roads and SH 82)? I believe this needs to be discussed if the intersection will be signalized. I would recommend the applicant and his traffic engineer schedule a pre -application meeting with CDOT to go over these concerns. If you have any additional questions, please let me know.

The State Highway Access Code (SHAC) does not require CDOT methodology approval but it is clearly in the best interest of the applicant to avoid having to pay for a second TIA if the first TIA methodology is unacceptable to CDOT. One of CDOT's objectives is to minimize the time and cost associated with the access permitting process. However, CDOT is responsible for safe and efficient highway operations and needs to have a clear understanding of the traffic impacts associated with land development projects. The CDOT website includes the following CDOT documents, which will be the basis for TIA preparation, review, and acceptance: • State of Colorado, State Highway Access Code, August 1998, as amended • CDOT Access Mgmt Unit, Recommended Outline for Traffic Impact Analysis (TIA), April 2003 In addition, the following documents serve as acceptable and recommended references: • ITE, Traffic Access and Impact Studies for Site Development — A Recommended Practice, 1991 • ITE, Trip Generation Handbook - A Recommended Practice, October 1998 • ITE, Traffic Engineering Handbook, 1999 • TRB, Access Management Manual, 2003 • ITE, Transportation and Land Development — 2nd Edition, 2002 The study methodology must be determined in conjunction with review agencies, preferably at a pre - study conference or phone call. The applicant can schedule a meeting with the CDOT Region 3 Access Engineer, Alisa Babler, and 970-683-6287 or alisa.babler@dot.state.co.us. The applicant is responsible to document methodology agreements and include the summary in the TIA appendix. A proper methodology should include, but is not limited to, agreement on the following information. 1. Study Area — highway segments and key intersections 2. Planned and programmed highway improvements that are separate from development 3. Analysis years and peak periods, as a function of development phasing 4. Highway access classification 5. Data sources and collection needs, peak to daily conversion factor 6. Traffic growth rates, sources, and method of application 7. Trip generation i) Rates ii) Reduction factors for internal capture and pass -by, etc iii) Seasonal adjustment factors iv) Special site studies 8. Trip distribution and assignment 9. Multi -modal considerations 10. Design vehicle and truck factor 11. Software used for initial and final operational analysis 12. Need for and methodology for traffic crash analysis CDOT R3 Traffic Section 1-2009 During Preparation of the TIA There may be questions that occur during preparation of the TIA and CDOT is available to discuss the proper course of action. The applicant can contact the CDOT Region 3 Access Engineer, Alisa Babler, and 970-683-6287. During Review of the TIA Please provide a name and phone number of the Colorado Professional Engineer that prepared the TIA. While most information should be included in the TIA, it may be necessary for CDOT to get TIA clarifications. After CDOT Review of the TIA. CDOT will prepare written TIA review comments and will send them to the permit applicant. The applicant has the following options in response to the review comments. • If in agreement with the review comments, address them by revising the TIA accordingly. • If not in agreement with the review comments, call to discus the issues or arrange a meeting to determine acceptable resolution. • If no agreement can be reached on CDOT R3 traffic requirements, the permit will be denied and the applicant can appeal the denial, per the SHAC. COLORADO DEPARTMENT OF TRANSPORTATION RECOMMENDED OUTLINE FOR TRAFFIC IMPACT STUDY Access Management Unit, CDOT February, 2008 GENERAL 1. Prior to submitting a formal application, the interested parties may request a pre -application conference with the issuing authority or Department to establish and agree upon base assumptions, including proposed traffic counts/volumes, and to determine if a Traffic Impact Study (TIS) must be submitted as a requirement of the State Highway Access Permit Application. CDOT considers this step beneficial to both the Applicant and CDOT because circumstances specific to the access can be identified and addressed early in the permitting process. 2. When a Traffic Impact Study (TIS) is required, it shall be completed and sealed by a Professional Engineer registered in the State of Colorado, preferably with specific training in traffic and transportation engineering. 3. In general, A TIS will be required when the proposed land use will generate a design hourly volume (DHV) of 100 trips or more, or when considered necessary or desirable by the issuing authority or the Department. The DHV is the 30th highest hour vehicular volume experienced in a one year period and is used in determining geometric design of highways. If this data is not available, then Peak Hour Volumes shall be used after being adjusted to the peak seasonal month. 4. In determining the extents of the area to include in the study, a general guide is to carry the analysis out at least as far as those areas where newly generated site traffic represents 5 percent or more of the roadway's peak hour capacity. 5. The TIS may only identify any anticipated waivers from the design standards of the Code as described in Section 4.12 of the State Highway Access Code. Waivers cannot be issued for procedural requirements. 6. The need for auxiliary lanes for any access is based on the highest peak hour volume generated within the entire day, for each turning movement. The TIS must look at both the peak hour of the generator and the peak hour of the adjacent street traffic. Traffic generated by the development will be used to evaluate the highest peak hour volume. Additionally, weekend generation rates must be evaluated depending on certain types of land uses, such as churches, shopping centers, and recreation facilities. 7. The TIS shall include evaluation of the current daily peak hour traffic data, any interim phases and 20th year projections. This includes turning movements at all intersections assuming a build- out of' the study area based upon zoning, comprehensive plans and growth estimates. This includes any newly approved development that has not been constructed. 8. Revisions to the TIS will be required if the study does not include the necessary information required by the Code, or if the data is not accurate, sufficiently thorough or representative of the proposed access and development plan. If a previous study for a project is more than 1 -year old, an updated study may be required.

Sherman Executive Director Dick Wolfe, P.E. Director Dear Kathy: We have reviewed the above -referenced proposal to subdivide a parcel of approximately 280 acres to contain a total of 1006 single-family and multi -family residential units, 71,000 square feet of commercial floor space and several community amenities, including an elementary school, pool and tennis club. The domestic water supply, including up to 7 acres of lawn and landscape irrigation (500 square feet per dwelling unit), and sewage disposal are to be provided by connection to the Roaring Fork Water and Sanitation District (RFWSD). The irrigation water supply is to be provided through the use of existing water rights in the Glenwood and Staton Ditches. The applicant is pursuing water rights through plans for augmentation decreed in Case No. 01CW187 and pending in Case No. 07CW164. These water rights will provide for water service to the development for up to 1200 EQR from either the RFWSD wells, from additional wells or from a surface water diversion, and will be augmented by the Basalt Water Conservancy District (BWCD) contract water from Ruedi and Green Mountain Reservoirs. These water rights will be transferred to the RFWSD once final decrees are obtained and upon inclusion of the property into the RFWSD. No information was provided concerning the physical adequacy of the water supply. As stated in C.R.S. 30-28-133(3)(d), the subdivider is required to submit "Adequate evidence that a water supply that is sufficient in terms of quality, quantity, and dependability will be available to ensure an adequate supply of water for the type of subdivision proposed." Adequate evidence is usually provided in the form of a water resource report, prepared by a professional engineer or water consultant, which addresses the quality, quantity, and dependability issues. A report of this nature was not provided. See the Updated Memorandum Regarding Subdivisions (online at www.water.state.co.us/pubs/policies/memo subdivisions.pdf) for the necessary information. Due to the lack of a water court -approved augmentation plan, the State Engineer finds pursuant to CRS 30-28-136(1)(h)(I), that the proposed water supply will cause material injury to decreed water rights and is inadequate. Also note that the use of the irrigation water rights must not result in an expansion of use, and approval of a change of water right application by the water court may be necessary if the place of use is changed. If you or the applicant has any questions concerning this matter, please contact me for assistance. Sincerely, Cynthia J. Love, P.E.

My comments are based on the 2003 International Fire Code (IFC) and the Garfield County amendments to it. Access roads: For the planned density of this PUD, the road system needs to meet the requirements stated in Section 503, Fire Department Access Roads in the 2003 IFC. If all the roads on the site are to be dedicated "Fire Department Access Roads" then some in the submitted plans do not meet the minimum road width stated in Section 503. The roads that do not meet Section 503 standards shall be improved so they do meet them. Minimum street width clearance at a fire hydrant is 26 feet for 20 feet on each side of the fire hydrant. By installing automatic fire suppression systems in most or all of the buildings in the PUD, narrower then code required road widths and steeper grades may -be allowed for some of the roads in the PUD if they are approved by the Authority Having Jurisdiction. Section 503.2.3 Dead ends: Dead-end fire apparatus roads in access of 150 feet in length shall be provided with an approved area to turn around fire apparatus. The plans state some of the dead -end roads are to be 200 feet in length. Water Supply for Fire Flow: The plan states a 1 million gallon water tank will be installed. I recommend that the applicant be required to provide a water modeling study to show that this amount of water in storage is adequate to meet the PUD water demand for fire flows and domestic use at total build out. If this tank is also to supply the H Lazy J Mobile Home Park, what impact will its demand have on the PUD's water supply? The amount of water for fire flow can be significantly reduces by requiring all the building in the PUD to have an automatic fire suppression system installed in them. Automatic Fire Protection in Buildings: Some of the proposed multi -family buildings will be required to be sprinldered by the 2003 IFC and all buildings 3 stories or more are required to be sprinklered by Garfield County amendment to Section 903.2 of the 2003 IFC. Some, if not all, proposed commercial buildings may be required to be sprinklered by the 2003 IFC depending on there occupancy and size. Note: If Garfield County adopts the 2009 International Codes by the time this PUD is approved and construction starts more stringent fire protection codes my apply. Impact Fees: We question the legality of charging the developer impact fees. According to the County Attorney Don DeFord they are illegal and can not be accessed in non -home rule areas of Garfield County. If you have questions on any of the above comments or need more information please contact me by phone 384-6433 or email.

Sherman Executive Director Vincent Matthews Division Director and State Geologist Thank for the submittal of the above referenced proposal, which was received on January 29, 2009. The proposal is to allow development of 1006 units, a school, open space and recreation. Due to adverse site conditions, a full inspection of the site was not possible. However, the site has been inspected in the past and previous descriptions of site conditions were used in this evaluation. Generally, the site has moderate slopes. Slopes steeper than 30 percent are present along terrace edges adjacent to the Roaring Fork River. A small alluvial fan sits in the northeast corner of the site. Also, as you know, the site contains numerous sinkholes caused by the dissolution of evaporate bedrock. The main geologic hazards outlined in the geotechnical report, by HP Geotech, dated August 12,2008 include the following: • Subsidence and sinkholes caused by dissolution of evaporite deposits • Expansive and collapsible soil • Slope instability along steep slopes adjacent to the river. The recommendations in the most recent geotechnical report are similar to those contained in an earlier version. Recommendations critical to protecting public safety include: • Buildings, roads, and underground utilities should not be placed on or near sinkholes. Recommended setbacks have been established for four sinkholes (called A, B, C and D in the HP Geotech report). • All other sinkholes should be fully investigated prior to approval of development plans. • If avoidance is not possible, roads can be constructed over stabilized sinkholes but buildings and critical utilities should not. • Buildings should be setback from the steep escarpment. A minimum setback of 2H:1 V should be measured from the edge of the river channel. Other recommendations that will impact the performance of buildings, roads, and utilities include: • Mitigation of expansive and/collapsible soil • Construction of an underdrain system • Restrictions regarding cuts and fills and other grading activities Ms. Kathy Eastley Page 2 February 23, 2009 • Mitigation of corrosive soil As outlined in the PUD Guide flexible, form -based codes will guide site development. As such, the PUD Guide focuses more on the physical form of the development and less on specific land use restrictions. The development will have an integrated system of trails, open space, public spaces, and storm -water management facilities. Generally, the guide has prescriptive (what is desired) rather than proscriptive (what is prohibited) standards. This will likely result in a more integrated vision for the development but it also raises some questions about how geologic hazards will be mitigated. Due to the scale of the geologic hazard map contained in the geotechnical report and other maps provided in the PUD Guide and supporting materials, I cannot accurately locate "non -buildable" areas. Given this, concerns considered critical to the protection of public safety are outlined below: • An area labeled as T41 is located adjacent to a potentially unstable escarpment. Page SC33 of the technical guide indicates that a slope setback is not required. This appears to be an error which should be corrected. • In the same technical guide, Area T32 contains a note that states slope setbacks will be "as required in the geotechnical report". In addition to slope setbacks, the geotechnical engineer recommends that sinkholes located near the escarpment must also be considered when developing slope setbacks. If the recommended 2H:1 V setback includes sinkholes, some building areas shown on the plans may not be feasible. This should be clarified before development plans are approved. • Several parts of Area T31 and T32 appear to encroach into required setbacks. Because buildings, roads, utilities should not be placed in these areas, it would be prudent to identify and fully dimension such areas on zoning and plat documents. To the extent possible, such areas should be designated as a natural zone. • Across the development, Use Areas appear to overlie or encroach onto sinkholes (investigated and uninvestigated) and areas of soil piping. Again, it would be prudent to identify and fully dimension such areas on zoning and plat documents. To the extent possible, these areas should be designated as a natural zone. • Before final development plans are approved, additional investigation should be done in areas labeled by HP Geotech as "approximate uninvestigated sinkhole". Until such investigations are completed, the full extent of, and required mitigation for, subsidence hazards cannot be determined. Currently plans show that various structures will be placed in such areas. • The PUD Guide contains environmental resource standards controlling storm water drainage and infiltration. It appears the goal is to mimic predevelopment hydrology by infiltration of runoff. The site contains soil with a high percentage of clay and silt. Fine-grained soil, once suspended in runoff, cannot effectively be removed using most sediment control measures. Infiltration and filtration of such runoff will help reduce potential water quality impairment. However, as outlined in the geotechnical report, any ponding or concentration of water can increase the dissolution of evaporite deposits and increase risks of subsidence. It is critical that all Best Management Practices be evaluated by the geotechnical engineer. It may not be wise to place rain gardens and wet ponds near sinkholes or buildings. It is not clear if the current storm water management plan has been reviewed by the geotechnical engineer. Other concerns and questions: • The geotechnical report recommends that underdrains are needed to protect below grade construction and that drains should be sloped to a gravity outlet. It is not clear in the geotechnical report, but given the site's geologic and soil constraints, as well as density, a main underdrain collection line may need to be constructed below sanitary sewer lines. Drains around individual buildings would then be connected to a main collection line and water daylighted at a main discharge point. This should be clarified before construction plans for roads are completed. Collection lines, and stubouts to each lot, would need to be installed as part of the public improvements. • All other recommendations provided by the geotechnical engineer should be followed. Ms. Kathy Eastley Page 2 February 23, 2009 In summary, it is important to note that even with the mitigation measures outlined above and in the geotechnical report, subsidence may occur and building, roads, and utilities may be severely damaged. The following quote from the geotechnical report should be strongly considered during the entitlement process. Even with mitigation it may not be possible to prevent some structural damage to buildings, but it should be feasible to prevent sudden collapse and provide a reasonable level of safety for the building occupants."

Berry Geological Engineer, PG, AICP, CPESC-SWQ FIRE • EMS • RESCUE February 12, 2009 Kathy Eastley Garfield County Building & Planning 108 8th Street, Suite 401 Glenwood Springs, CO 81601 RE: Cattle Creek Colorado PUD, Zone District Amendment Dear Kathy: I have reviewed the Zone District Amendment for the proposed Cattle Creek Colorado Subdivision. The application was reviewed for compliance with the International Fire Code (IFC) 2003 edition, adopted by the County. I would offer the following comments. Access The proposed access throughout the subdivision generally appears to be adequate for emergency apparatus. Water Supplies for Fire Protection The Roaring Fork Water & Sanitation District has agreed to service the development. The applicant has proposed to install a one -million gallon water tank and install the appropriate size water mains necessary to connect to the existing Roaring Fork Water & Sanitation District's water system. The proposed system appears to be capable of providing adequate fire flows throughout the development. Location and spacing of fire hydrants shall be in accordance with IFC Appendix C. H Lazy F Mobile Home Park The applicant has been granted a road and utility easement through the H Lazy F Mobile Home Park. The easement will allow access from the Fire District's station located on County Road 154 directly to the development through H Lazy F. The easement will also allow the applicants proposed water system to be extended through H Lazy F. H Lazy F currently has a PUD application submitted to the County and is need of water for fire protection as are the other adjacent properties. Both proposed developments would benefit from the easement.

Summary of Submittal Components Reviewed: 1. Traffic Impact Analysis 2. Geotechnical Study 3. Drainage 4. Utility Report 5. Internal Street Configuration and Roadway Design Standards Traffic Impact Analysis Summary of Traffic Analysis Provided By Developer • Scope: The submitted analysis examines how the development will access State Highway 82. The analysis did not include a traffic analysis of proposed roads within the development. • Location of Highway Access Points: The report concludes that the development will be served by two access points: (1) a main access point at the existing intersection of SH 82 & CR113, and (2) a second access point onto the southbound lane of SH 82. This second access is referred to as a right -in right - out (RIRO) intersection. [The development has chosen not to connect to a third access point at SH 82 & CR114 (north of development) because this access will harm the performance of the RIRO intersection. The analysis does not explain how this third access adversely affects the RIRO intersection.] • New Signal at SH 82 and CR113: The analysis concludes that a traffic light is currently warranted at SH82 and CR113 regardless of the proposed development. Engineer's Questions and Comments Regarding Traffic Analysis 1. Lack of Analysis for Interior Roads: The analysis was performed only for the access points onto SH 82. Considering the unconventional elements within the street layout, a traffic analysis must be performed for the streets within the development. Items of concern are the number of vehicles that need to queue at the main entrance, multiple functions that some streets are expected to fulfill, the 1 traffic volume on the narrow streets, and the number of turns and stops that vehicles needs to make to reach the entrance. 2. Connection with Lazy H Ranch (comment added 2/2/09): What is the status of the access through the Lazy F and the improvements shown for this intersection on Highway 82? 3. Traffic Counts: Where and when were the traffic counts performed? 4. Split between Traffic Heading North and South: What is the basis for assuming that during A.M. weekday peak hour 60% of the exiting traffic heads south towards Carbondale and Aspen? Similarly, what is the basis for assuming that during the P.M. weekday peak hour that 35% of the entering traffic returns from the south? If, in the morning, 60% of the vehicles go up valley (to south), shouldn't a similar percentage of vehicles return from up valley (from south) in the evening? Even if the percentages aren't identical, the number of vehicles leaving towards the south in the morning should be the roughly the same number returning from the south in the evening. 4. Division Between Dwellings Using Each Entrance: The study does not provide information on which dwellings will use the north RIRO access point and which will use the main south access point onto SH 82. It is not clear if this was considered in the traffic impact analysis. For example, all vehicles returning from up valley (from the south) will need to use the main entrance at SH 82 & CR 113 since the RIRO entrance only serves vehicles coming from down valley (from the north). 5. SH 82 & CR 114 Intersection and the Connection of Development to North: Why does a connection from the north end of the development adversely affect the RIRO access? 6. CDOT Access Permit: The SH 82 access configuration is something that the developer needs to negotiate with CDOT. What is the status of communications with CDOT? At the time of preliminary plan, the County expects that all negotiations between the developer and CDOT will be finalized. 7. Intersection of CR 110, CR 113, frontage road and SH 82: The development will trigger the installation of a traffic light on SH 82. The traffic light will necessitate improvements to the intersection on the east side of SH 82. It is reasonable to require that the developer share in cost of these improvements. 8. Predicted Traffic Volume per Roadway Capacity (V/C Ratio): How was this ratio calculated? Several V/C ratios greater than 1 were reported. Doesn't a V/C>1 indicate that the volume is greater than the capacity and that the level of service (LOS) is 'F'? 9. Table 8: Footnotes are missing from table. HP Geotech's Geotechnical Study — Conclusions and County's Comments 1. Investigated Sinkholes: As the underlying evaporite rock strata dissolves, the ground subsides causing sinkholes. Borings performed around the sinkholes encountered the evaporate strata at depths between 48 feet and 113 feet. Borings that were drilled outside the sinkhole areas were shallower than 20 feet and 2 therefore were not deep enough to reach the evaporite strata. Presumably the evaporate strata underlies the entire site. 2. Sinkholes not Investigated: A large uninvestigated sinkhole area exists across the south end of the property. Houses and utilities are proposed in this area. Prior to preliminary plan, additional borings are needed in this area. 3. Pertinent Recommendations of HP Geotech's Study: (1) Identified sinkhole areas should be avoided as building sites, road alignments and underground wet utilities. (2) Additional evaluation is needed of uninvestigated sinkhole areas. (3) Prospective homeowners/property owners should be made aware of subsidence potential. (4) Buildings need to be designed to prevent sudden collapse in the event of subsidence. (5) Buildings must be setback 10-15 feet from top of the river terrace escarpments. (6) Underdrains are recommended for all foundations. These underdrain pipes will need to discharge to the surface or to drywells. (See comments regarding underdrains in drainage study review. 4. Summary of County's Comments: (1) Further geotechnical evaluation is needed prior to submitting the preliminary plan. (2) Roadways, utilities and building sites can not be placed in sinkhole areas that are delineated on the HP Geotech map dated 8/12/08. (3) Purchasers of properties must be made be aware of the subsidence (i.e. sinkhole) risk. (4) All foundations and structures must be designed to avoid sudden collapse. Drainage Report 1. Highlights of Proposed Drainage System: • This pre -design report provides only design criteria; no calculations regarding pipe sizes, retention areas, etc. • Proposed design will use swales and other landscaping features to optimize infiltration and to detain and treat the runoff from impervious surfaces. • The developer proposes to increase the peak runoff flows leaving the site. They rationalize that peak flows from the site will enter Cattle Creek and the Roaring Fork River before the peak flows in these two rivers will occur. 2. Impact on Evaporative Strata and Sinkholes: The developers propose to maximize infiltration of the stormwater into the soil. In areas where the site is underlain by an evaporative strata (also referred to as a hydro-compactive strata), they propose to limit infiltration or using linings to limit infiltration. County's comment: Evidence suggests that the entire site may be underlain by the evaporative strata. Thus, there may be no areas within the site that infiltration of runoff should be promoted. HP Geotech needs to review the areas proposed for stormwater infiltration and certify that the infiltration will not increase subsidence. 3. Increases in Post Development Runoff Flows: As mentioned above, the developer proposes to forgo sufficient stormwater detention that would prevent post -development flows from exceed pre -development flows. Developer believes 3 this acceptable as long as the peak flows from the development enter Cattle Creek and the Roaring Fork River before peak flows occur in these streams. In the opinion of the County's engineer, the developer should be required to detain runoff so that peak runoff flows do not exceed pre -development flows. It is easy to imagine localized storm events that would cause peak flows in the Cattle Creek or Roaring Fork River to coincide with non -detained peak runoff flows from the Cattle Creek development. The County's engineer supports the efforts of the developer to treat runoff from impervious areas using landscaped areas throughout the development. Because the level of treatment is directly proportional to the length of detention, it is difficult to envision how treatment can occur without stormwater detention. 4. Foundation Underdrains: The geotechnical report recommends that each building foundation needs piped underdrains. At the time of preliminary design, the developer should explain how flows from underdrains will be handled. 5. Drainage Section of County's New Land Use Code (comment added 2/2/09): Development should comply with all requirements of Section 706 of the County's new code. Utility Report 1. Legal and Physical Water Supply: The Cattle Creek development seeks to obtain drinking water from the Roaring Fork Water and Sanitation District (RFWSD). Cattle Creek has entered into a pre -inclusion agreement with RFWSD that outlines Cattle Creek's financial responsibilities including the need to fund a new water source for RFWSD (either surface water or a well). RFWSD is currently in the process of obtaining water rights to be able to supply the Cattle Creek development. The Cattle Creek development will physically connect to Aspen Glen and to RFWSD on the other side of the Roaring Fork. Engineer's question: How and where will the water and sewer pipes cross the river? 2. Sewer: Sewer service is also included in the pre -inclusion agreement with RFWSD. The sewers within the development will gravity flow to a lift station from which sewage will be pumped across the Roaring Fork River to RFWSD sewage treatment plant. RFWSD plans to increase the capacity of its treatment plant in 2010. Engineer's comment: The report indicates that the planned 2010 treatment plant expansion will not provide adequate treatment capacity of Cattle Creek at build -out. Another expansion of the treatment facility will be needed before the Cattle Creek development can be completed. 3. Raw Water for Irrigation: RFWSD will provide enough water to irrigate seven acres. Through water rights on the Glenwood and Staton Ditches and a piped raw water distribution system, the remaining of the development will be irrigated. Engineer's Question: What area of land can be irrigated with the ditch water? 4. Dry Utilities — Gas, Electric, and Telecommunications: The preliminary plans need to show allow all utility boxes and pedestals. Alleys and lanes must be kept free of pedestals (and dumpters) to preserve the ROW for emergency vehicle access. 4 5. Utility River Crossings (comment added 2/2/09): What type of permission does the developer need to allow pipelines to cross the Roaring Fork Conservancy easement? (Such construction will need to take place during non -nesting months.) Internal Street Configuration and Roadway Design Standards (comments revised 2/2/09) The submitted conceptual design does not provide quantitative details for an engineering review of roadway geometry, site distances, emergency access, parking configuration, etc. Reviewing the proposed `Smart' Code, the following comments address the proposed departures from conventional design standards. 1. Connections to North: The application's Transportation Master Plan shows two street connections to existing streets on the north end of the development. These connections do not concur with the traffic impact analysis. It is the County's expectation that one of these north access points will exist for emergency access. 2. Highway 82 Access Points: The Transportation Master Plan does not show the additional turn lanes that will be needed at the SH 82 intersections. 3. Widths of Roadways Serving Multiple Functions: (a) Stores and parking spaces abut streets that provide a thoroughfare through the development. Such multiple uses will cause traffic stoppages. (b) Bicycle use is hindered by the prevalence of narrow streets and the lack of bicycle lanes. (c) Some streets will require turn lanes. (d) The County's engineer recommends that the minimum width of travel lanes on major streets be no less than 12 foot. 4. ROW Width: One hundred years ago city planners had the foresight to create wide right-of-ways that have been able to accommodate unimagined innovations such as motorized traffic, parking, sanitary and storm sewers, underground dry utilities, and bicycle lanes. Because of these wide ROWs, towns have had the flexibility to implement improvements. In order to maximize lot areas, the proposed development is asking for variances from the County's ROW requirements. This is short sighted. 5. Alleys and Lanes: (a) Alleys and lanes serve multiple functions including garbage collection, utilities, and emergency access. Dead-end alleys and lanes may not provide these functions and should be discouraged. (b) If garages are placed on alleys, a 20 foot distance is needed in front of the garage door to allow cars to access the garage. (c) Parking should not be allowed in alleys or lanes unless adequate width is reserved for emergency vehicles. 6. Snow Removal and Street Cleaning: Street and curb design must accommodate snowplows and street sweepers. Areas must be reserved to receiving snow from a plow and areas for receiving snow trucked away from streets. 7. Public Transportation: Streets must be designed to accommodate buses and bus stops. 8. Stabilized Landscaping: Stabilized landscaping is proposed along roadsides to accommodate the turning of large vehicles such as fire trucks. Stabilized landscaping is also proposed for emergency access easements. The emergency access easement will need to be plowed in the winter. It is unlikely that the 5 stabilized landscaping on the inside of intersections and around cul-de-sacs will be plowed and, as such, is an acceptable solution for the County. 9. Roadway Curves: Compound, Short Arc, and Reverse: Complex roadway alignments may serve to slow traffic but will also create unsafe conditions when mixed with bad weather and elderly or distracted drivers. 10. Permeable Pavement: Applicant needs to demonstrate that the proposed permeable pavement works in this climate. 11. Road Shoulders: When there is no curb, a stabilized roadway shoulders (3 -foot wide minimum on both sides) is necessary to keep the pavement from prematurely deteriorating. 12. Parallel Parking on Turns: Parallel parking should never be placed on turns since there is inadequate sight distance. 13. Garbage Collection: Show where garbage collection will occur. (Where will the recycling center be located?)_. Internal Road Comments on the Smart Code Summary, Technical Binder, Tab 2 (comments added 2/2/09) Street Type A: • Summary: This is a short street that goes through a retail commercial area. It is the only street with diagonal parking. • Diagonal Parking: An 18 -foot wide land is reserved for diagonal parking. This is inadequate considering that a typical pick-up truck (single cab F-250) requires a 19.8 -foot lane measured perpendicular to the curb (calculated using 60 degree parking angle). Furthermore, a crew cab F-250 pick-up requires a 22.3 -foot parking lane measured diagonally from the curb. • Snow Storage: To open the road immediately after a snow storm, the snow must be plowed to the center of the road or onto the shoulders. With the narrow travel lanes and diagonal parking, there is no room for snow storage. Street Types B, C, D, F, G (main thoroughfares): • Summary: These are the streets with the highest traffic that will be used to access Highway 82. (Some of the F and G street types are not main thoroughfares.) • Parallel Parking: Parallel parking will stop traffic. This is unacceptable on these high volume streets. • Snow Storage: Inadequate. See comment for Street Type A. • Bicycle Lanes: No bicycle lanes have been provided. Streets are too narrow for safe bicycling. Bicycling on the sidewalks should be discouraged • Turning Lanes: Turning lanes at some intersections will be needed. Current street widths and right-of-way widths will not accommodate turning lanes. Street Types F & G (not main thoroughfares): • Summary: For discussion purposes, these are the Type F & G streets that will be used than less than 40 dwellings (approximately 400 average daily trips (ADTs). 6 • Snow Storage for Street Type F: See comment for Street Type A. (Street Type G do not having parking on one side allowing snow to be plowed out of the road.) Street Type E — (one-way 'slip lane'): • Summary: Only one short street Type F is proposed. The street has a one-way 10 -foot wide travel lane and one lane of parallel parking. • Inadequate for Emergency Vehicles. Per the International Fire code, even one- way alleys have to be 20 -foot wide travel surface if they are to serve as a fire access road. Street Type H: - I couldn't find such a street in the development. Street Type J (residential `yield' street): • Summary: Low traffic residential streets wit a single 12 -foot lane to accommodate 2 -way traffic. • International Fire Code: The International Fire Code states that: (1) A fire access roads must extend within 150 feet of all portions of buildings. (2) Fire access roads shall be 20 -feet wide and designed and maintained to support the imposed loads of fire apparatus and shall be surfaced so to provide all-weather driving capabilities. (3) Dead-end roads in excess of 150 feet shall be provided with an approved area for turning around a fire apparatus. • Limit on Daily Trips: Such roads are clearly inadequate to serve the 400 average daily trips proposed in the application. • Parking: Where will visitors park? Will the road's shoulders accommodate parking? Street Type L (lane): • Summary: These are 12 -foot wide roads have two-way traffic. Most are dead- end without provisions for emergency vehicle turn around. In different places these lanes serve different functions ranging from (i) shared driveways, (ii) alleys providing secondary access to the property, or (iii) dead-end roads serving multiple homes. • Applicability as Shared Driveways: It is my recommendation that these shared driveways be limited to 3 homes. As stated by the fire code, these driveways need to be 20 feet wide and be no longer than 150 feet. • International Fire Code: See comments for Type J Streets. Roads must have a 20 foot wide unobstructed surface that can support a fire truck. • Applicability as Dead-end Roads: Absolutely no dead-end roads should be 12 - foot wide. Per County code, no dead-end roads can be over 600 -foot long or lack a paved cul-de-sac turnaround. • Split Roadway: I assume that these `islands' have been placed along the roadway to allow vehicles to pass (especially emergency vehicles). What was the criterion used for spacing these islands? Street Type M (one-way allies): 7 • Summary: Alleys should provide secondary access to dwellings for utilities, garbage collection, and garage access. As proposed, some of the allies provide the only access to dwellings. • Dead-end Allies: Obviously, no dead-end one-way allies should have been proposed. Ideally allies should be straight and connect to main streets. If a bend in the ally is proposed, the bend must allow large vehicles to turn. • Sole Access: Allies cannot be the only access for primary or accessory dwellings. • Alley Width: Per the International Fire Code an unobstructed 20 foot width is required To allow for fire truck use, allies must have a minimum 12 -foot wide pavement with have 4 -foot stabilized shoulders on each side (20 -foot total). Nothing, including parking, utility pedestals and parked cars, can ever obstruct this 20 -foot ROW width. (See International Fire Code in Type K Street comments) Additional Roadway Design Standards (Technical Binder, Tab 2, Table 5 and 6) The following are requested modifications from County regulations or roadway design standards. (Frankly, there are no reasons why a new development cannot comply with these time -tested standards that have been established for safety reasons.) 1. Bridge Width: The County's engineer cannot approve the reduction of bridge widths without seeing more details. Roadway width over bridges must be wide must have a minimum travel surface of 22 -foot wide for cars and a sidewalk. A bicycle lane(s) may also be necessary. The International Fire Code, states that bridges must be constructed and maintained in accordance to AASHTO specifications. 2. Signage: Signage (i.e. stops signs) can not be modified from MUTCD standards. 3. Curb Radii: The proposed curb radii that are as small as 5 foot can be used as long as it can be geometrically demonstrated that that trucks and emergency vehicles (i.e. fire trucks) can make the turn without crossing into ongoing traffic lanes or crossing over the curb. (The County can be more flexible when it comes to entrances into allies.) The County will not allow stabilized landscaping on the inside of intersections to be used to accommodate the turning of large vehicles since these areas is unlikely to be plowed in the winter. 4. Parking Surface: The County is open to considering the use of porous pavement if the applicant can demonstrate its functionality in cold climates and longevity with supporting the expected vehicle loads. 5. Intersection Offset Separation and Driveway Separation from Intersection: Intersections must be directly across from each other or be separated by a distance of 200 feet. 6. Horizontal and Vertical Curves vs. Sight Distance: To prevent accidents, the design must comply with AASHTO and other generally accepted standards for sight distance and curves. (Note: Curves should be placed at the vertical crests or low points in roads.) 8 7. Dead-end Streets: Dead-end streets cannot be over 600 -foot long. All dead- end streets required a paved turnaround area. Stabilized pavement will not be plowed in the winter and cannot constitute part of the area required for the turnaround. 8. Furnishing in the R.O.W.: No structures, utility pedestals, utility boxes, dumpsters, private trash containers, and private (reserved) parking can be placed in the R.O.W. (The applicant should submit a list of items which they wish to allow in the R.O.W.) 9. Intersection Angle less than 60 Degrees: County will approve only on a case- by-case basis in which applicant demonstrates that topography does not allow the street to be designed to comply with >60 degree angle. 10. Snow Removal. Where there is parking on both sides of the road, the road must be wide enough that snow can be plowed to the middle of the road prior to the snow being hauled away. 11. Shoulders. If there is no curb stabilized road shoulders (3 -foot wide minimum on each side) are essential for the durability of the paved driving surface. 12. Table 6: Emergency Vehicle Access: (1) County will not allow the development to use stabilized landscaping to meet requirements for turnarounds since there is no guarantee that these areas will be kept open and plowed in the winter. (2) Per the Fire Code, a shard driveway cannot be longer than 150 feet unless an adequate turnaround is provided. (3) Per the Fire code, a 20 foot wide lane is needed if the road is needs to serve as a fire access road. This means that all roads must be 20 feet wide. 9 Section Section 4.00 Planned Unit Developments SEE ALSO CATTLE CREEK APPLICATION, TECHNICAL BINDER, TAB 4 `RESPONSE TO STANDARDS AND REQUIREMENTS' 4.01 Definitions 4.01.01 Common Open Space 4.01.02 Plan 4.01.06 Density 4.01.03 Planned Unit Development 4.01.07 Fractional Ownership Interest 4.01.04 Commencement of Development 4.01.08 Ownership 4.01.05 Contiguous 4.02 Purposes and Objectives of Development 4.03 Scope 4.04 Consistency With the Master/Comprehensive Plan 4.05 Relationship to Zoning and Subdivision 4.05.01 Applicability to PUDs 4.05.02 Waiver or modification of specification 4.06 Internal Compatibility of Planned Unit Developments 4.07 Standards and Requirements 4.07.01 Approval of PUD rezoning 4.07.02 Off-street parking spaces 4.07.03 Site plan criteria 4.07.04 Maximum height of buildings 4.07.05 Lot areas and setback restrictions 4.07.06 Residential density 4.07.07 Minimum acreage 4.07.08 Uses permitted 4.07.09 Common open space 4.07.10 Time-share/fractional 4.07.11 Findings of the PUD Development Regulations Section (4.07.11 — 4.07.15 NOT INCLUDED IN THIS DOCUMENT) 4.07.12 Purpose 4.07.13 General 4.07.14 Definistions 4.07.15 Requirements 407.15.01 For Lands Designated High Density Residential 4.07.15.02 For Lands With Any Land Use Designation Other Than High Density Residential 4.07.15.03 Computation of Required Affordable Housing Units and Mix of Housing Units 4.07.15.04 PUD Amendment Requests Subject To These Regulations 4.08 PUD Processing (NOT INCLUDED IN THIS DOCUMENT) 4.08.01 Review of applications 4.08.02 Application process 4.08.03 PUD plan 4.08.04 Use and occupancy restrictions 4.08.05 Application requirements 4.08.06 Use prior to approval 4.09 Development in Stages (NOT INCLUDED IN THIS DOCUMENT) 4.09.01 Time limits 4.09.02 Late application 4.09.03 Failure to proceed to a subsequent stage 4.09.04 Nonresidential uses 4.09.05 Development & Construction 4.10 Maintenance of Common Open Space (NOT INCLUDED IN THIS DOCUMENT) 4.11 Fee (NOT INCLUDED IN THIS DOCUMENT) 4.12 Enforcement and Modification of Provisions of the Plan (NOT INCLUDED IN THIS DOCUMENT) 4.12.01 Common Open Space 4.12.02 Enforcement of provisions 4.12.03 Modifications of provisions 4.12.04 Removal of rights to enforce 4.12.05 Independent or Outside Legal and/or Technical Expertise 4.14 Garfield County Affordable Housing Guidelines (NOT INCLUDED IN THIS DOCUMENT) 4.14.01 Renting, Purchasing, or Selling Affordable Housing Units -Qualifications to Rent or to Purchase Affordable Housing Units 4.14.02 Qualifications to Reside in an Affordable Housing Unit 4.14.03 How to Qualify for Affordable Housing Unit (Rental or Purchase) 4.14.04 Procedures for Initial Purchase and for Resale of an Affordable Housing Unit 4.14.05 Execution of Deed Restrictions by Applicants 4.14.06 Priorities for Persons Desiring to Purchase an Affordable Housing Unit 4.14.07 Maximum Vacancy of an Affordable Housing Unit for Rent 4.14.08 Leave of Absence for Owners of an Affordable Housing Unit 4.14.09 Roommates 4.14.10 Special Review for 4 to 6 Bedroom Units 4.14.11 Grievance Procedures 4.00 PLANNED UNIT DEVELOPMENTS 4.01 DEFINITION As . used in this Planned Unit Development Section (hereafter "section") the following defmitions shall apply, unless the context otherwise requires: 4.01.01 Common Open Space: A parcel or parcels of land, or a combination of land and water within the site designated for a Planned Unit Development, designed and intended primarily for the use or enjoyment of residents, occupants and owners of the Planned Unit Development.

A "planned" mass transit terminal or station, is herein defined as a facility identified in a bonafide and endorsed conceptual planning process by an agency or authority with legal standing to undertake alternatives analysis and conceptual design, and where that facility has progressed to the preferred or selected alternative for preliminary design, and where it can be reasonably assumed that such facility will be built within 20 years. The 2000 foot radius, where the facility is not yet in place or designed, shall be deemed to be from the center point of a probable location. Where there may be several probable locations in a given area, the Applicant may show such alternatives and accommodate those in the conceptual design and Sketch Plan of a TPUD in consultation with the board and to assist in review by a Mass Transit Agency. (added 2002-12) 4.01.04 Commencement of Development: Approval of a Final Plat and commencement of construction as secured by a Subdivision Improvements Agreement. (A. 97-109) 4.01.05 Contiguous: When applied to parcels of land, shall mean the lands have a common border and adjoin each other on at least one common property boundary, for a minimum of thirty (30) feet. For the purposes of this definition, a pubhc right-of-way or easement shall be considered a common property boundary for properties separated only by right-of-way or easement. (A. 97-109) Contiguity, for purposes of creating a TPUD cannot be gained by a common boundary with a fixed guide way alone. A planned or developed mass transit terminal or station must be within 2000 feet. (added 2002-12) 4.01.06 Density: The overall average residential density shall be calculated by summing the number of residential dwelling units planned within the boundary of the PUD and dividing by the total gross area, expressed in acres, within the boundary of the PUD. (A. 97-109) 4.01.07 Fractional Ownership Interest: Any type of shared ownership or leaseback of a structure intended primarily for residential occupancy that results in occupancy shares being allotted for a designated period of time. (A. 97-109) 4.01.08 Ownership: Demonstration of ownership shall be constituted by current written proof of who or what entity holds title to all of the land(s) depicted on any plat or plan filed with the County, with the minimum proof of ownership consisting of a title report issued by a title company authorized to conduct business in the State of Colorado. The title report shall be issued not more than fifteen (15) days prior to the date of submittal of the PUD application. If the land is owned by a corporation or similar legal entity, that designates an individual or entity to act in the Corporation's or similar legal entity behalf, a proof of agency shall be required and consist of a Corporate Resolution, or similar legal document, designating the individual or entity to act as agent. The application must be signed by an officer of the Corporation or legal entity and certified by the Secretary of the Corporation, or officer of a similar legal entity. (A. 97-109) 4.02 PURPOSES AND OBJECTIVES OF DEVELOPMENT The purpose of a PUD is to permit greater design flexibility and, consequently, more creative and imaginative design for development than generally possible under conventional zoning and subdivision regulations. It is intended that PUDs shall be planned to insure general conformity, both in substance and location, with the goals and objectives of the master/comprehensive plan through integrated development. (A. 97-109) The purpose of a TPUD is more fully set out in §5.11. (added 2002-12) 4.03 SCOPE Applications for Planned Unit Development zoning may be made for land located in any zoning district. 4.04 CONSISTENCY WITH THE MASTER/COMPREHENSIVE PLAN No PUD or TPUD shall be approved unless it is found by the County Commissioners to be in general conformity with the County's Master/Comprehensive plan(s). When appropriate, an application for an amendment to the Garfield County Master/Comprehensive Plan may be made as part of a PUD application. Any application for Master/Comprehensive Plan amendment must be approved by the Planning Commission, prior to its recommendation on the PUD application, and may occur at the same meeting. Applications for Comprehensive Plan amendment shall include justification for the amendment based upon criteria for establishing land use designations contained in the Master/Comprehensive Plan. (A. 97-109) (added 2002-12; TPUD) 4.05 RELATIONSHIP TO ZONING AND SUBDIVISION 4.05.01 The Garfield County Subdivision Regulations, as the same may be from time to time amended, and the provisions of this Zoning Resolution, as the same may be from time to time amended, shall be applicable to PUDs insofar as said Regulations and Resolution are consistent with this section and with any specific zoning or subdivision requirements approved by the County Commissioners at the time of zoning or platting the PUD in question. To the extent that said Regulations and Resolution are inconsistent herewith, they shall not be applicable and the provisions of this section and, with respect to TPUDs, supplementary regulations in §5-12 shall control. (amended 2002-12) 4.05.02 It is recognized that the uniqueness of each proposal for a PUD and TPUD requires that the specifications, standards and requirements for various facilities, including but not limited to, affordable housing, streets, highways, alleys, utilities, curbs, gutters, sidewalks, street lights, parks, play -grounds, school grounds, storm drainage, water supply and distribution, and sewage collection and treatment, may be subject to modification from the specifications, standards, and requirements established in the Subdivision Regulations of Garfield County for like uses in other zone districts. The County Commissioners may, at the time of zoning as a PUD and TPUD, waive or modify the specifications, standards and requirements which would be otherwise applicable, as requested by the applicant. Any waiver or modification of specifications, standards and requirements will only be approved if it can be demonstrated that the proposed waiver(s) is consistent with "best engineering practices," as recommended by an engineer retained by the County. (A. 97-109) (amended 2002-12) 4.06 INTERNAL COMPATIBILITY OF PLANNED UNIT DEVELOPMENTS It is recognized that certain individual land uses, regardless of their adherence to all the design elements provided for in this section, might not exist compatibly with one another. Therefore, a proposed PUD or TPUD shall be considered from the point of view of the relationship and compatibility of the individual elements of the Plan, and no PUD or TPUD shall be approved which contains incompatible elements internally or with neighboring property. (amended 2002-12) 4.07 STANDARDS AND REQUIREMENTS 4.07.01 The County Commissioners may approve a proposed PUD rezoning upon a finding that it will implement the purposes of this section and will meet the standards and requirements set forth in this section. A TPUD must also meet the additional standards and requirements set forth in the supplementary regulations found in §5.11 of this resolution. (amended 2002-12) 4.07.02 The number of off-street parking spaces for each use in each PUD shall not be less than the requirements for like uses in other zoning districts, except that the County Commissioners may increase or decrease the required number of off-street parking spaces in consideration of the following factors: (1) Estimated number of cars owned by occupants of dwellings in the PUD; APPLICANT NEEDS TO PROVDE JUSTIFACTION FOR THE REDUCTIONS IN PARKING PROVIDED FOR RESIDENCES AND OTHER USES. A PARKING PLAN SHOULD BE SUBMITTED THAT TABULARIZES THE PARKING REQUIREMENTS FOR EACH MULI-FAMILY AND NON- RESIDENTIAL BUILDING AND A MAP THAT SHOWS THE PARKING SPACES RESERVED FOR EACH BUILDING. (2) Parking needs of non -dwelling uses; (3) Varying time periods of use wheneveroint use of common parking areas is proposed. THE APPLICANT PROPOSES SHARED (JOINT) PARKING TO REDUCE PARKING SPACES BUT DOES NOT PROVIDE INFORMATION ON THE VARYING TIME PERIODS OF EACH USER. 4.07.03 The PUD shall meet the following site plan criteria unless the applicant can demonstrate that one (1) or more of them is not applicable or that a practical solution has been otherwise achieved: (1) The PUD shall have an appropriate relationship to the surrounding area, with unreasonable adverse effects on the surrounding area being minimized. (A) NATURAL ENVIRONMENT. COUNTY WILL REVIEW THE OPINIONS OF EXPERTS TO DETERMINE IF THE UNDISTRUBED PARTS OF THE SITE ARE ADEQUATE FOR WILDLIFE CORRIDORS AND HABITAT. (B) TRAFFIC. THE ADDITIONAL TRAFFIC AND STOPLIGHT ON HIGHWAY 82 WILL HAVE A NEGATIVE AFFECT. IN ADDITION, USE OF THE RFTA REGIONAL TRAIL AS A RECREATIONAL AMENITY COULD HINDER THE USE OF THE TRAIL BY BICYCLE COMMUTERS. (2) The PUD shall provide an adequate internal street circulation system designed for the type of traffic generated, safety, separation from living areas, convenience and access. Private internal streets may be permitted, provided that adequate access for police and fire protection is maintained. Bicycle traffic shall be provided for when the site is used for residential purposes. (A) PRIMARY TRAFFIC ROUTE THROUGH DEVELOPMENT IS NOT SEPARATED FROM LIVING AREAS. THESE PRIMARY ACCESS ROUTES ARE NARROW AND HAVE JOGS AND THEREFORE CONVENIENCE AND ACCESS ARE SACRIFICED. (B) IT APPEARS THAT THERE IS ADEQUATE ACCESS FOR EMERGENCY VEHICLES. THIS JUDGEMENT NEEDS TO BE CONFIRMED BY THE POLICE AND FIRE DEPRTMENT AT THE TIME OF PRELIMINARY PLAN. THE APPLICANT PROPOSES TO REDUCE CURVE RADII AT INTERSECTIONS. TO ACCOMMODATE THE LARGE TRUNING RADII OF LARGE VEHICLES (LIKE FIRE TRUCKS), STABILZED LANDSCAPING IS PROPOSED ON THE INSDE OF INTERSECTIONS SUCH THAT TRUCKS CAN DRIVE OVER THE CURB AND ACROSS THE LANDSCAPING. STABILIZED LANDSCAPING IS ALSO PROPOSED FOR EMERGENCY ACCESS EASEMENTS. THE AREAS OF STABILIZED LANDSCAPING WILL NEED TO BE PLOWED IN THE WINTER. (C) THE PRIMARY TRAFFIC ROUTES ARE NARROW AND NOT DESIGNED FOR BICYCLE TRAFFIC. (3) The PUD shall provide parking areas adequate in terms of location, area, circulation, safety, convenience, separation and screening. APPLICATION SHOWS THAT PARKING AREAS ARE SURROUNDED BY TREES. THE APPLICANT NEEDS TO DEMONSTRATE THAT THE SIZE OF THESE PARKING AREAS IS ADEQUATE TO FULFILL THEIR FUNCTIONS. FOR EXAMPLE, IS THERE ENOUGH PARKING FOR THE SCHOOL AND PLAYING FIELDS? (4) The PUD shall provide Common Open Space adequate in terms of location, area and type of the Common Open Space, and in terms of the uses permitted in the PUD. The PUD shall strive for optimum preservation of the natural features of the terrain. APPLICATION SHOWS LARGE AND SMALL PARKS THROUGHOUT DEVELOPMENT. (5) The PUD shall provide for variety in housing types and densities, other facilities and Common Open Space. BA)) HOUSING TYPES AND DENSITIES: SEE APPLICATION TECHNICAL INDER, TAB 1, PAGE SC15 `TABLE 1: SMART CODE SUMMARY' (B) OTHER FACILTIES: OK (C) COMMON OPEN SPACE: OK (6) The PUD shall provide adequate privacy between dwelling units. OK (7) The PUD shall provide pedestrian ways adequate in terms of safety, separation, convenience, and access to points of destination and attractiveness. OK (8) If centralized water and/or wastewater facilities are proposed within the PUD, they shall be provided for in a separate utility zone district that shall contain its own performance standards. No land within any utility zone district shall apply toward any category of open space calculation or requirement. The PUD shall demonstrate how common water and wastewater facilities will be controlled or governed by the future owners within the PUD. (A. 97-109) NOT APPLICABLE (9) Any disturbance of slopes in excess of 40%, shall be the minimum necessary to meet the development needs, with a revegetation and geotechnical plan submitted with the PUD application. (A. 97-109) NOT APPLICABLE 10) If community facilities are proposed to be contained or allowed in the PUD, the application shall discuss who or what entity shall be responsible for the provision of and payment for the proposed facilities. The facilities shall also be included within the overall common infrastructure requirements of the PUD, to include water, wastewater and parking requirements. (A. 97-109) A. SITE FOR SCHOOL: PER DRAFT AGREEMENT BETWEEN APPLICANT AND SCHOOL DISTRICT, APPLICANT WILL PROVIDE LAND, UTILITIES TO SITE, AND PLAYING FIELDS. B. PLAYING FIELDS. COUNTY COULD REQUIRE THAT PLAYING FIELDS BE CONSTRUCTED IN CONJUNCTION WITH THE HOMES, NOT WHEN THE THE SCHOOL IS CONSTRUCTED (AS PROPOSED BY THE APPLICANT). C. NEIGHBORHOOD PARKS. D. FISHING POND. E. RFTA ROW. 4.07.04 The maximum height of buildings may be increased above the maximum permitted for like buildings in other zone districts in relation to the following characteristics of the proposed building: SEE APPLICATION TECHNICAL BINDER, TAB 1, PAGES SC25, SC31-SC35 (1) It's geographical location; (2) The probable effect on surrounding slopes and mountainous terrain; (3) Unreasonable adverse visual effect on adjacent sites or other areas in the immediate vicinity; (4) Potential problems for adjacent sites caused by shadows, loss of air circulation or loss of view; (5) Influence on the general vicinity, with regard to extreme contrast, vistas and open space; and (6) Uses within the proposed building. (7) Development supportive of mass transit operations in a TPUD. (added 2002-12) 4.07.05 The maximum lot areas and the minimum setback restrictions may be decreased below and the maximum lot coverage may be increased above those applicable to like buildings in other zone districts to accommodate specific building types with unusual orientation on the lot or relationship between buildings. The averaging of lot areas shall be permitted to provide flexibility in design and to relate lot size to topography, but each lot shall contain an acceptable building site. The clustering of development with useable common open areas shall be permitted to encourage provision for, and access to, common open areas and to save street and utility construction and maintenance costs. Such clustering is also intended to accommodate contemporary building types which are not spaced individually on their own lots but share common side walls, combined service facilities or similar architectural innovations, whether or not providing for separate ownership of land and buildings. Architectural style of buildings shall not be a basis for denying approval of a PUD application. SEE APPLICATION TECHNICAL BINDER, TAB 1, PAGES SC25, SC31-SC35 COUNTY COULD REQUIRE THAT A PRE -DETERMINED PERCENTAGE OF BUILDINGS BE CONSTRUCTED TO BE `SOLAR PANEL READY' AND THAT BUILDINGS BE ORIENTED FOR PASSIVE SOLAR (LIGHTING AND HEATING) AND SOLAR PANELS. 4.07.06 The overall residential density shall be no greater than two (2) dwelling units per gross acre within the PUD; provided, however, that the County Commissioners may allow an increase to a maximum of fifteen (15) dwelling units per gross acre in areas where public water and sewer systems, owned and operated by a municipal government or special district (as defined by Section 32-1-103(20), C.R.S.) are readily available and the prior zoning classification allowed residential densities greater than two (2) dwelling units per gross acre, such increased densities shall nevertheless comply with the maximum lot coverage, minimum setback, maximum floor area ratio, maximum building height and parking standards of such prior zoning classification. The overall average residential density shall be calculated by summing the number of residential dwelling units planned within the boundary of the PUD and dividing by the total gross area expressed m acres within the boundary of the PUD. The density of dwelling units in any particular area may be greater than the maximum permitted for a like use in other zone districts. Averaging and transferring of densities within the PUD shall be allowed upon a showing of conformance with the purposes of this section through appropriate design features within the PUD that will achieve high standards of design and livability. (A. 83-93, A. 96-87, A. 97-109) (amended 2002-12) NUMBER OF PROPOSED RESIDENTIAL DWELLING UNITS: 1006 GROSS ACRES: 288.9 ACRES UNITS/ACRE: 3.5 SEE GARFIELD COUNTY ZONING CODE, SECTION 3.05 FOR: MINIMUM LOT AREA (20,000 SF), MAXIMUM LOT COVERAGE35%), SETBACKS, MAXIMUM BUILDING HEIGHTS (25 FT), AND FLOOR AREA RATIO (0.25). Where the application is a TPUD, and showing of conformance with the purposes of this section is deemed appropriate by the board, limitations set on previously zoned density of under two dwelling units per gross acre may be removed and the applicant may propose higher overall densities and exceed standard building height limitations otherwise specified herein, provided only that standards specified in 4.07.04 are considered. Special attention shall be given to fire protection and equipment needs triggered by such a proposal. Any proposal requesting a density above 5 dwelling units per gross acre within 2000 feet of a proposed or developed mass transit station or terminal shall provide 10% additional affordable housing units (In Study Area One, a total of 20%) with those units being within 2000 feet of the proposed station or terminal, even though previous zoning did not allow that level of density for those developments within 2000 feet. The intent of this section of the Resolution is to permit both the PUD allowance of increased density provided that 10% of the proposed units are affordable units, and an additional increased density, where increased density is proximate to and supports a transit station or terminal, and that higher density within 2000 feet of the transit station or terminal. The applicant must show a concentration of affordable units equaling 20% of the proposed housing stock where density exceeds five units per acre in Study Area One. (A. 83-93, A. 96-97, A. 97- 109) (amended 2002-12) TO BE DETERMINED BY COUNTY HOUSING AUTHORITY 4.07.07 The minimum number of acres that may comprise a PUD is two (2) acres. OK 4.07.08 All uses, which are permitted in the underlying zone district or consistent with the land use designations in the Comprehensive Plan, or approved as an amendment to the Comprehensive Plan, may be permitted in PUDs. (A. 95-043, A. 97-109) NEED AMENDMENT TO COMPREHENSIVE PLAN? The uses, which shall be permitted in any particular PUD shall be those permitted by the resolution zoning the particular area PUD. 4.07.09 Twenty-five percent (25%) of the total area within the boundary of any PUD shall be devoted to Common Open Space. Not more than twenty-five percent (25%) of the Common Open Space shall be an area of water classified as commercial open space. Of the 25% open space requirement within PUDs, no more than 40% of the 25% total required, shall be limited use open space, with the balance being retained as one or more of the remaining open space categories, listed above. Provided, however, that the County Commissioners may reduce such requirement if they fmd that such decrease is warranted by the design of, and the amenities and features incorporated into the Plan, and that the needs of the occupants of the PUD for Common Open Space can be met in the proposed PUD. (A. 97-109) LIMITED USE OPEN SPACE: COMMON OPEN SPACE: REQ'D: <55.1 AC (40% OF 137.9 AC) CC: 17.2 AC (12.5%) REQ'D: 72.2 AC (25% OF 288.9 TOTAL PUD) CC: 137.9 AC (47.7%) 4.07.10 If any zone district within the PUD is proposed to contain time-share or fractional ownership units, or other similar interest in property, the provisions for such ownership shall be those that are approved by the Board of County Commissioners at the time the property is zoned PUD. NO TIME SHARE OR FRACTIONAL OWNERSHIP IS PROPOSED. 9:00 DESIGN AND IMPROVEMENTS STANDARDS 9:10 GENERAL SITE STANDARDS 9:11 In designing and planning individual lots and street layout for a subdivision, the constructed improvements and engineering design shall conform to the provision of this Section 9:00, as well as to other applicable Garfield County land use regulations and standards. 9:12 Land subject to identified natural hazards, such as falling rock, land slides, snow slides, mud flows, radiation, flooding or high water tables, shall not be platted for any use other than open space or an uninhabitable portion of a lot over two (2) acres, unless mitigation is proposed by a Colorado registered professional engineer qualified to do such design. CATTLE CREEK AND ROARING FORK FLOODPLAINS: THEY WILL NEED A FLOODPLAIN DEVELOPMENT PERMIT FOR BRIDGES AND ANY OTHER IMPACTS TO THE CATTLE CREEK FLOODPLAIN. THE ROARING FORK FLOODPLAIN WILL NOT BE IMPACTED. POTENTIAL SUBSIDENCE: THE ENTIRE SITE NEEDS TO BE THOROUGHLY INVESTIGATED FOR EXISTING AND POTENTIAL SINKHOLES. AT MINIMUM, THE RECOMMENDATIONS IN THE GEOTECHNICAL REPORTS MUST BE FOLLOWED. OTHER: NO OTHER NATURAL HAZARDS LISTED ABOVE APPEAR TO OCCUR. Land subject to flooding, or in a natural drainage channel, shall not be platted for occupancy unless adequate provision has been made to eliminate or control any potential flooding. In no case shall a project conflict with the standards and requirements established in the Garfield County Floodplain Regulations. 9:13 Development plans shall preserve, to the maximum extent possible, natural features such as unusual rock formations, lakes, rivers, streams and trees. Where appropriate, the subdivider may be required to dedicate lands to lot owners to preserve these features. In no case shall lots be designed such that a dwelling unit will be located closer than thirty feet (30') to a live stream, lake or pond, regardless of the fact that floodplain regulations may allow dwelling units located closer in some instances. NO BUILDINGS PROPOSED WITHIN 30 FEET OF STREAMS. HERON ROOKERIES: QUOTING THE LITERATURE, THE WILDLIFE ASSESSMENT REPORT STATES THAT RECOMMENDED BUFFER ZONES (FREE OF HUMAN ACTIVITIY) AROUND HERON NESTS IS 200 METERS TO 500 METERS.

THE PLAT RECORDED BY THE ROARING FORK CONSERVANCY AND THE APPLICANT SHOWS A 200 METER RADIUS WITH ITS CENTER NEAR THE CONFLUENCE OF CATTLE CREEK AND THE ROARING FORK RIVER. THERE APPEARS TO BE AT LEAST ONE BUILDING AND TWO YARDS WITHIN THIS RADIUS. THE WILDLIFE ASSESSMENT REPORT IDENTIFIES THREE HERON NEST TREES FURTHER UPSTREAM FROM THE CONFLUENCE AND GRAPHICALLY SHOWS A 200 METER BUFFER AROUND THE NESTS. THERE ARE DEFINITELY A NUMBER OF HOMES WITHIN 200 METERS OF THESE NEST SITES. THE DEVELOPER PLANS NOT CONSTRUCT HOUSES WITHIN 200 METERS OF THE NESTS UNTIL THE HERON'S ABANDON THE NESTS. AUTHOR OF THE REPORTS BELIEVES THAT HERONS WILL ABANDON THIS NESTING AREA AS DEVELOPMENT OUTSIDE THE 200 METER RADIUS OCCURS. 9:14 Public access and/or fishing easements to lakes, rivers and streams shall be provided as a part of any development proposal where it is determined to be appropriate by the Board of County Commissioners. TWO FISHING ACCESS POINTS ARE PROPOSED ON THE SOUTH (UPSTREAM) END OF THE PARCEL ALONG THE ROARING FORK. THESE FISHING ACCESS POINTS ARE WITHIN 200 METERS OF THE HERON NEST TREES. PER THE RECOMMENDATIONS OF THE WILDLIFE ASSESSEMENT REPORT, THESE ACCESS POINTS SHOULD BE CLOSED DURING BREEDING SEASON MID -MARCH TO JULY 31ST 9:15 One (1) dog shall be allowed for each residential unit within a subdivision; and the dog shall be required to be confined within the owner's property boundaries. The requirement shall be included in the protective covenants for the subdivision, with enforcement provisions allowing for the removal of a dog from the subdivision as a final remedy in worst cases.

STREETS ARE NOT NAMED YET. 9:32.2 No more than two (2) streets shall intersect at one point, with a minimum of two hundred feet (200') between off -set intersections, unless otherwise approved by the County Road Supervisor. THERE ARE MULTIPLE PLACES IN WHICH PROPOSED BLOCK LENGTHS AND OFFSET DISTANCES BETWEEN INTECTIONS ARE LESS THAN 200 FEET. 9:32.3 Streets shall be designed to bear a logical relationship to the topography. OK 9:33 Cul-de-sacs and dead end streets may be designed under the following circumstances: THREE DEAD END STREETS EXCEED 600 FOOT LENGTH. (1) SOUTH STREET ENDS IN A 1400 -FOOT LONG DEAD END STREET . (2) THE SOUTH END OF EAST STREET ISA 1600 -FOOT LONG DEAD END BUT ASSUMABLY THE DEVELOPER WILL CORRECT THIS DEFICENCY BY CREATING AND MAINTAINING AN EMERGENCY ACCESS ROUTE FROM THE END OF EAST STREET, ACROSS THE RFTA TRAIL, TO THE FITNESS CENTER PARKING LOT. (3) THE NORTH END OF EAST STREET IS SHOWN AS CONNECTING WITH THE FRYWALD CONSTRUCTION. HOWEVER, THE ACCESS ACROSS FRYWALD CONSTRUCTION IS TEMPORARY AND DOES NOT PROVIDE FOR A PERMANENT SECONDARY ACCESS. AS SUCH, THIS AREA ONLY HAS ONE ACCESS POINT. A. Cul-de-sacs may be permitted provided they are not more than six hundred feet (600') in length and have a turnaround radius of not less than forty-five feet (45') from the center of the cul-de-sac to rad edge and fifty foot (50') right-of-way for residential development and not less than seventy-five foot (75') right-of-way for commercial/industrial development where tractor trailer trucks will enter the property or by providing a T-shaped turnaround with a minimum turning radius of fifty feet (50') for residential development and seventy-five feet (75') for commercial/industrial development where tractor trailer trucks will enter the property. The Board may approve longer cul-de- sacs for topographical reasons and it can be proved that fire protection and emergency egress and access is provided as a part of the longer design; and B. Dead end streets shall be discouraged, except in cases where the dead end is meant to be temporary with the intent to extend or connect the right-of-way in the future. If a dead end street is approved, room for plowed snow storage shall be included by providing a T-shaped turnaround with a minimum turning radius of fifty feet (50') for residential development and seventy-five feet (75') for commercial/industrial development where tractor trailer trucks will enter the property. A dead end street being different from a cul-de-sac in that a dead end street has no permanent turnaround at the end of the street. PROPOSED TURNING RADII ARE LESS THAN REQUIREMENT. TURNING RADII ARE A HEALTH AND SAFETY ISSUE AND ARE NOT NEGOTIABLE. 9:34 All streets are dedicated to the public but all streets will be constructed to standards consistent with these Regulations and repair and maintenance shall be the responsibility of the incorporated Homeowners Association of the subdivision. MAINTENANCE OF ALL STREETS WILL BE THE RESPONSIBILITY OF THE HOMEOWNERS'S ASSOCIATION. 9:35 Street and roadway design shall be in conformance with the following standards: THE STREET STANDARDS PROPOSED BY THE APPLICATION VARY SIGNIFICANTLY FROM THE COUNTY'S STANDARDS.

IN GENERAL, IT IS THE OPINION OF THE COUNTY'S PLANNING ENGINEER IS THAT THE PROPOSED PRIMARY TRAFFIC ROUTES ARE TOO NARROW TO ACCOMMODATE: (i) PARALLEL PARKING FROM ADJACENT SHOPPING AREAS, (ii) BICYCLISTS, (iii) A CONVENIENT THOROUGHFARE TRAFFIC FROM RESIDENTIAL AREAS TO HIGHWAY 82, (iv) QUEUING AT INTERSECTIONS, AND (v)TEMPORARY SNOW STORAGE IN THE MIDDLE OF THE ROAD. RIGHT-OF-WAY (ROW) WIDTH: ONE HUNDRED YEARS AGO CITY PLANNERS HAD THE FORESIGHT TO CREATE WIDE RIGHT-OF-WAYS THAT HAVE BEEN ABLE TO ACCOMMODATE UNIMAGINED INNOVATIONS SUCH AS MOTORIZED TRAFFIC, PARKING, SANITARY AND STORM SEWERS, UNDERGROUND DRY UTILITIES, AND BICYCLE LANES. BECAUSE OF THESE WIDE ROWS, TOWNS HAVE HAD THE FLEXIBILITY TO IMPLEMENT IMPROVEMENTS. IN ORDER TO MAXIMIZE LOT AREAS, THE PROPOSED DEVELOPMENT IS ASKING FOR VARIANCES FROM THE COUNTY'S ROW REQUIREMENTS. THIS IS SHORT SIGHTED.

General consideration shall be given to the interrelationship between the length of grade; its relation to curves and intersections and the transition between those elements of a road. At a minimum, in order to approve the requested variance, the following standards shall be met: EXCESSIVE ROAD GRADES ARE NOT EXPECTED. 1. The applicant shall, by way of graphic illustration on a topographic map, show the difference between a road that would comply with the grade requirements and the proposed road with excessive grade. 2. The excessive grade is necessary to avoid the creation of a cut or the fill slope that exceeds twelve(12) feet in height at the top of the cut or the bottom of the hill. 3. That the excessive grade section is the minimum length and the minimum increase in grade necessary to provide access to all lots. 4. The excessive grade has a slope with exposure to maximize solar exposure and minimize snow/ice build up. 5. All excessive grades in excess of 150 feet in length on dead end roads shall have a turnaround approved by the appropriate fire district as to the adequacy of the turnaround to meet fire equipment requirements. 6. If the applicant has not proposed or obtained Board of County Commissioner approval for fire fighting water storage of adequate capacity at the top of the excessive grade, the proposed excessive grade must permit the transport of such water. If the Board of County Commissioners find that a wild fire hazard is present in the proposed subdivision, the applicant for a variance to the maximum permissible grade must meet the following additional criteria: BECAUSE THE DEVELOPMENT IS LOCATED BETWEEN HIGHWAY 82 AND THE RIVER, WILD FIRE HAZARD IS NOT EXCESSIVE. 1. Excessive grades shall only be approved if, in the judgement of the local fire fighting authority, the wildfire hazard presents a danger due to excessive vegetation, inadequate land widths or inability to transport water. 2. In areas where wildfire hazard presents a danger, excessive grades shall only be approved if landscaping requirements consistent with Forest Service recommendations to minimize wildfire hazards are not incorporated into the covenants of the subdivision. 3. A variance to the maximum grade shall only be allowed if the use of roof shingles and siding of the structure are built out of something other than fire retardant materials and/or sprinklers for internal structural fire protection are not mandated by covenant. 9:40 DRAINAGE: APPLICANT WILL NEED TO PROVIDE PLAN THAT COMPLIES WITH THIS PROVISONS. 9:41 Drainage easements, channels, culverts and required bridges shall be designed by an engineer registered in the State of Colorado. 9:42 All drainage facilities shall be designed based on a twenty-five (25) year frequency storm. 9:43 Where new developments create run-off in excess of historic site levels, the use of detention ditches and ponds may be required to retain up to a one hundred (100) year storm. 9:44 All culverts shall be designed such that the exposed ends are protected by encasement in concrete or extended a minimum of three feet (3') beyond the driving surface on each side. Culverts, drainage pipes and bridges shall be designed and constructed in accordance with AASHO recommendations for an H-20 live load. 9:50 WATER SUPPLY. APPLICANT WILL NEED TO PROVIDE PLAN THAT COMPLIES WITH THIS PROVISONS. 9:51 An adequate potable and irrigation water supply shall be available to all lots within a subdivision, taking into consideration peak demands to service total development population, irrigation uses, and adequate fire protection requirements in accordance with recognized and customary engineering standards. 9:52 Individual wells may be used as the water supply, provided the applicant has submitted the required documentation to the appropriate water court, and the Colorado Division of Water Resources will approve well drilling permits for all lots within the development. 9:53 Central water systems shall be designed by an engineer qualified to design water systems and be a registered professional engineer licensed by the State of Colorado. Central water and treatment and storage facilities shall be approved by the Colorado Department of Health. All lines in a central water system should be looped, with no dead ends included in the system. Where dead ends are proposed for cul-de-sacs, there will either be a fire hydrant or blow -off valve at the end of the line. 9:54 Water supply systems, on -lot or otherwise located in a floodplain, shall be designed to minimize or eliminate infiltration and avoid impairment during or subsequent to flooding. 9:55 All water mains shall be a minimum diameter of four inches (4"), provided storage facilities adequate for fire protection are available. 9:60 SANITARY SEWAGE DISPOSAL APPLICANT WILL NEED TO PROVIDE PLAN THAT COMPLIES WITH THIS PROVISONS. 9:61 Disposal by individual sewage disposal systems may be permitted, provided lot sizes are consistent with the Garfield County Zoning Resolution. Individual systems must have representative soil absorption tests performed by a qualified engineer registered to perform such tests in the State of Colorado. 9:62 Central sewage treatment works shall be designed by a registered professional engineer licensed by the State of Colorado. The system shall be designed, in accordance with the standards established by the Colorado Department of Health. Site location approval shall be obtained from the Colorado Water Quality Control Commission for systems over two thousand (2,000) gallons per day. In no event may a system be designed for less capacity than the anticipated maximum daily sewage flow or treatment requirements. 9:70 FIRE PROTECTION APPLICANT WILL NEED TO PROVIDE PLAN THAT COMPLIES WITH THIS PROVISONS. 9:71 Subdivision fire protection plans shall be reviewed by the appropriate fire protection district to ensure that all lots have primary and secondary access points to escape fire entrapment. 9:72 Where a central water system has fire hydrants, all fire hydrants shall meet the specifications for the appropriate fire protection agency, particularly with regard to thread size on the fire hydrants. 9:73 Where there is no central water system available, a central located fire protection storage tank shall be designed to meet the fire protection needs of the subdivision and be approved by the appropriate fire district. 9:74 Water used for fire protection purposes does not have to be potable water and may be from a source separate from the domestic supply. 9:80 PUBLIC SITES AND OPEN SPACES The Board shall require the reservation and dedication of sites and land areas for schools and parks when such are reasonably necessary to serve the proposed subdivision and future residents. The applicant shall make Dedication of the sites and land areas to the County, to a School District, or to the public or, in lieu thereof, payment of a sum of money not exceeding the fair market value of the sites and land areas. School site or park acquisition cash in lieu shall be based upon a study of the fiscal impact on the district by new subdivision development, approved by the Board of County Commissioners and Planning Commission. The use of any such fees shall be limited by the provisions of CRS §30-28-133, as amended. (99-096) SCHOOLS: LAND IS BEING RESERVED FOR ELEMENTARY SCHOOL. PARKS: PARKS THOROUGHOUT THE DEVELOPMENT WILL BE OPEN TO THE PUBLIC AND MAINTAINED BY THE HOMEOWNER'S ASSOCIATION. RECOMMENDATIONS FOR ADDITIONAL PUBLIC SPACES/FACILITIES: DEVELOPMENT SHOULD CREATE A COMMUNITY GARDEN AND A RECYCLING CENTER. 9:81 For property located in the RE -1 School District, the subdivider of land in each residential subdivision or portion of a subdivision which is intended for residential use, shall allocate and convey sites and land areas for schools when such are reasonably necessary to serve the proposed subdivision and future residents thereof, by the application of formulas set forth below: Land area provided per student x students generated per dwelling unit = Land Dedication Standard. According to current school site size recommendations and reasonable building capacities, the District has determined that 1,776 square feet of land per student shall be provided for future school sites as stated below: Reasonable Capacity Recommended Acreage* Elementary School 550 15.5 Middle School 600 26.0 High School 800 38.0 Totals 1950 79.5 Total acres per student 0.04077 Total square feet per student 1,776 *Recommended acreage for school sites is based on the recommendations contained in the Guide For Planning Educational Facilities, published in 1991 by the Council of Educational Facility Planners International. The number of students generated per type of dwelling unit shall be based on the following: Single Family 0.49 Multi -Family 0.38 Mobile Home 0.71 Application of the formula results in the following Land Dedication Standards: Single Family 870 sq. ft. per unit or .020 acres Multi -Family 675 sq. ft. per unit or .015 acres Mobile Home 1,261 sq. ft. per unit or .029 acres Based upon the RE -1 School District's recommendation, the Board of County Commissioners can require a developer of residential housing to make a cash payment in -lieu of dedicating land, or may make a cash payment in combination with a land dedication to comply with the standards of this regulation. The formula to determine the cash -in -lieu payments as follows: Unimproved per acre market value of land x Land Dedication Standard x # of units = Cash -in -lieu. Unimproved market value of the property shall be determined by an appraisal performed within the last 24 months for the applicant, by an individual qualified in the State of Colorado to establish the unimproved market value of the property just prior to the approval of a Final Plat. Any dispute of the market value would be based upon a separate appraisal by an individual qualified in the State of Colorado to establish the value, paid for by the School District. (99-096) MEMORANDUM To: Kathy Eastley From: Steve Anthony Re: Cattle Creek Crossing Zone District Amendment Date: February 10, 2009 Thanks for the opportunity to comment on the Zone District Amendment. My comments are as follows: Noxious Weeds Rocky Mountain Ecological Services (RMES) has mapped and inventoried the area for State and County listed noxious weeds. In Section 6.2.1 of the Wildlife Assessment Report, RMES details priorities of weed control for the site. Staff encourages Cattle Creek Colorado (CCC) and the Roaring Fork Conservancy (RFC) to follow these priorities, specifically the St. Johnswort and oxeye daisy located on the lower bench in the conservation easement area. Staff will contact RFC and CCC and set up an on-site meeting in the spring of 2009 to discuss noxious weed priorities for the conservation easement. Covenants When the covenants are submitted at final plat, the applicant is encouraged to provide more detailed information on the following: • Common area weed management -The applicant needs to address weed management in common areas including road rights of way, parks, and open space. Issues to address are monitoring, treatment, and funding. • Covenants -If the subdivision will have covenants this is an opportunity to encourage weed control with new property owners, and to let them know that they are legally obligated to manage county listed noxious weeds. Revegetation and Soils This has been deferred until the preliminary plan application. At that time the items listed below need to be addressed. Revegetation The revised Revegetation Guidelines from the Garfield County Weed Management Plan (adopted on May 7, 2001) calls for the following: • Plant material list. • Planting schedule. • A map of the areas impacted by soil disturbances (outside of the building envelopes). • A revegetation bond or security at Preliminary Plan and prior to Final Plat. Please provide a map or information, prior to final plat that quantifies the area, in terms of acres, to be disturbed and subsequently reseeded on road cut and utility disturbances. This information will help determine the amount of security that will held for revegetation. The security shall be held by Garfield County until vegetation has been successfully reestablished according to the attached Reclamation Standards. The Board of County Commissioners will designate a member of their staff to evaluate the reclamation prior to the release of the security. Soil Plan The Revegetation Guidelines also request that the applicant provide a Soil Management Plan that includes: • Provisions for salvaging on-site topsoil. • A timetable for eliminating topsoil and/or aggregate piles. • A plan that provides for soil cover if any disturbances or stockpiles will sit exposed for a period of 90 days or more. To: Garfield County Commissioners Re: Cattle Creek Colorado proposed development Date: February 4, 2009 Please, please, please do not let Related Westpac ruin the Cattle Creek area The area in question will, m time, return to its natural state and will always be a refreshing oasis between housing developments and ugly strip malls. Just take a trip to Base Village at Snowmass to get an idea of what that company considers "good taste." The community laughed/cried at Gerald Hines' redevelopment of the base of Aspen Highlands, and Westpac proceeded to do the same thing at Snowmass. So much for original thinking. Are we really obligated to provide housing for every California refugee? Can the highway handle thousands of additional cars? And just where are the job opportunities? Please don't throw our beautiful valley even more out of balance. Be proud of the legacy you leave. frO&AL k C& Katherine Reppa Missouri Heights • sill Spence 678 North Bridge Drive Carbondale, Colorado 81623 970.963.2163 Phone; 909.548.8464 Fax bilspence@gmail.com RECEIVED SEP 2 2 2008 GARFIELD COUNTY BUILDING & PLANNING September 15, 2008 Subject: Cattle Creek Crossing Dear Members of Garfield County Planning and Zoning Commission, and Garfield County Commissioners, This letter is in regard to the proposed 979 -unit development at Cattle Creek. I am one of many county residents who believe that the proposed development is out of scale for the mid valley, would cater to the needs of up -valley employers who are not taking care of their own, and have very large economic and sociological impacts on infrastructure in the mid -valley. I have not had the opportunity to review the sketch plan for this development and my position is based on newspaper accounts and conversations with many individuals. Area residents will be watching very closely what Garfield County approves for the development at Cattle Creek. Several years ago, residents were appalled by the destruction of the beautiful Red Barn. Then, they were appalled further by the pre -construction earthmoving on that property which caused great destruction of elk habitat. The wintering elk herd is a significant and much honored part of our valley's culture. The County Commissioners denied a 500 -unit development of the predecessor Sander's Ranch and not very long ago authorized a development up to just 600 units. Why should the present development proposal be viewed more favorably? Using the standard assumption of 2.3 residents/unit implies that 979 units would house about 2250 residents — in essence an entirely new community in the mid - valley. This community would not particularly self-sustaining, in that it is mostly residential without proportionate commercial/retail development. Such a community would lead to a great deal of driving and a quality of life that is not in keeping with the "tone" of our valley. It is not clear to me what the impacts, including operating and construction costs, would be on regional schools, libraries, water treatment facilities, law enforcement, fire/emergency response, and other infrastructure elements. Similarly, are there plans for an on-site public library, a recreation center, a reasonably -sized grocery store, gas station, wide pedestrian trails connecting to the Rio Grande Trail, pedestrian nature trails within the Open Space along the Roaring Fork easement, necessary infrastructure elements, etc.? What provision exists for governance within Cattle Creek Crossing? The plan appears to be reminiscent of sub -urban type sprawl. It would be most helpful to see an analysis of the proposed distribution of housing stock, including the affordable and attainable components, in terms of the real needs within this section of our valley. For example, this proposal doesn't consider the contributions to affordable housing from major projects in Carbondale: the Overlook, Thompson Park, the Village at Crystal River (formerly the Marketplace project), and the property surrounding the former Carbondale Elementary School. Each of these has a considerable affordable housing component. These major projects that have been years in the planning stage but now detailed proposals are in the hands of Carbondale officals. Carbondale's Keator Grove is nearly completed, which is claimed to provide affordable/attainable housing, as does the Archdiocese development there. think that for a dynamic, vital, healthy community at Cattle Creek, we need to provide for and encourage a real diversity in housing stock and lifestyles. Other regional entities recently have moved projects away from concentrations of high density -- most recently with the Eagle River Station project. I think that housing diversity at Cattle Creek would enhance marketability of those units in our regionally competitive environment. As with the present design of Cattle Creek, Carbondale's Overlook project utilizes a variation of the transect approach (as in Smart Code). The transect approach could help the transition from the present proposal to one that embodies a greater diversity in housing stock. The developer is planning some "green" elements in this project. That will lessen the overall environmental impact of the project. However, buildout of the present proposal will have a huge traffic impact on CO 82, requiring major intersection modifications, and lead to a correspondingly large carbon footprint on our valley. In some regards, the present proposal appears better than predecessor proposals — it has plans for an elementary school at inception and a middle school later, it includes plans for a RFTA Transit Station, it ties into the completed Rio Grande Trail, and it has elements of "green" architecture. However, it appears that the developer's concepts are leading the process, rather than this project being guided by comprehensive GarCo planning. believe that Garfield County Planners, the GarCo P&Z, and the GarCo Commissioners should determine what would be an optimum development for the Cattle Creek site, in the context of what is healthiest for the whole mid -valley, and lead the developers in that direction. The vast majority of persons whom I have talked with concerning the Cattle Creek proposal feel that it has far too many dwelling units, has the feel of a community of commuters (with a host of impacts on regional infrastructure), and has the fundamental weakness of lacking initiatives that will contribute to a self- sustaining and healthy community. I urge Garfield Counter leaders to take steps to make Cattle Creek Crossing a presence in the valley of which we all can be proud. With your help, the development at Cattle Creek Crossing can be a strong mid -valley amenity rather than a marginal asset or even a liability. Sincerely, Bill Spence Copies to: Fred Jarman Garfield County P&Z and Commissioners (via Fred Jarman's office) Ed Green Bruce Christiansen Jeff Haeckel Michael Hassig Tom Baker Doug Dotson Dan Blankenship Jacque Whitsett Dorothea Farris Ed Cortez —�oOD spR, February 27, 2009 To: Kathy Easterly, County Planner From: Ron Biggers, Deputy Fire Marshal, Glenwood Springs Fire Department Re: Comments on Cattle Creek Colorado PUD, Zone District Amendments This proposed PUD is not in our Fire District but Carbondale Fire Department may request our Department for mutual aid to assist them in mitigating an emergency event in this PUD should if be built. My comments are based on the 2003 International Fire Code (IFC) and the Garfield County amendments to it. Access roads: For the planned density of this PUD, the road system needs to meet the requirements stated in Section 503, Fire Department Access Roads in the 2003 IFC. If all the roads on the site are to be dedicated "Fire Department Access Roads" then some in the submitted plans do not meet the minimum road width stated in Section 503. The roads that do not meet Section 503 standards shall be improved so they do meet them. Minimum street width clearance at a fire hydrant is 26 feet for 20 feet on each side of the fire hydrant. By installing automatic fire suppression systems in most or all of the buildings in the PUD, narrower then code required road widths and steeper grades may -be allowed for some of the roads in the PUD if they are approved by the Authority Having Jurisdiction. Section 503.2.3 Dead ends: Dead-end fire apparatus roads in access of 150 feet in length shall be provided with an approved area to turn around fire apparatus. The plans state some of the dead —end roads are to be 200 feet in length. Water Supply for Fire Flow: The plan states a 1 million gallon water tank will be installed. I recommend that the applicant be required to provide a water modeling study to show that this amount of water in storage is adequate to meet the PUD water demand for fire flows and domestic use at total build out. If this tank is also to supply the H Lazy J Mobile Home Park, what impact will its demand have on the PUD's water supply? The amount of water for fire flow can be significantly reduces by requiring all the building in the PUD to have an automatic fire suppression system installed in them. GARFIELD COUNTY Building & Planning Department Review Agency Form Date Sent: January 22, 2009 Comments Due: February 12, 2009 Name of application: Cattle Creek Crossing Sent to: Garfield County requests your comment in review of this project. Please notify the Planning Department in the event you are unable to respond by the deadline. This form may be used for your response, or you may attach your own additional sheets as necessary. Written comments may be mailed, e-mailed, or faxed to: Garfield County Building & Planning Staffs contact: Kathy Eastley 109 8th Street, Suite 301 Glenwood Springs, CO 81601 Fax: 970-384-3470 Phone: 970-945-8212 General Comments: Garfield County Road & Bridge Department has no objection to this application with the following comments. The entrance from Marand Road to Colorado State Highway 82 is not a County road so no driveway permit is needed for this entrance. Future entrances to Cr. 154, 114 and Cr.113 if not within the CDOT ROW will need to be permitted and all improvements to these intersections shall be approved by Garfield County Engineers. Any vehicles using Garfield County portions of Cr. 154, 114 and Cr. 113 hauling equipment and materials for construction of this project shall abide by Garfield County's oversize/overweight permit system. Any vehicles requiring oversize/overweight permits shall apply for them at Garfield County Road & Bridge Department. Any utilities placed in County Row or work performed within County Row shall be permitted by Garfield County Road & Bridge Department. Any work within County ROW shall have a traffic control submitted to Garfield County Road & Bridge Department and approved prior to any work being performed. After further review of the intersection of NO NAME ROAD at the intersection to Cr. 154 any added traffic load would require improvements to the intersection. An engineered design of the intersection shall be submitted to the Garfield County Engineer for approval prior to any work being performed. Without the improvements to the intersection no added traffic load should be allowed. Name of review agency: Garfield County Road and Bridge Dept By: Jake B. Mall Date January 29, 2009 Revised 3/30/00 Memo To: FILE From: Kathy Eastley, Planner Date: February 25, 2009 RE: Summary of Meeting - February 24, 2009 - CDOT/Hwy 82 Access Issues The purpose of the meeting was to examine the pending development in a three mile stretch of Highway 82 between the County Road 154/Hardwick Bridge Intersection through the Cattle Creek Intersection. Kathy Eastley reported that pending development in that area could total 1800 new homes, with a possible trip generation of 18,000 vehicle trips per day. The Highway 82 Intersections that will be impacted are the Cattle Creek Intersection, the CMC/County Road 114 Intersection, and the County Road 154/Hardwick Bridge Intersection. Dan Roussin from CDOT indicated that State Highway 82 is classified as an expressway and has very limited access. The access is protected through the State Highway Access Code and those rules in that Access Code are followed with respect to request for access permits. He indicated that the discussions about the Cattle Creek development have gone through two or three different owners and the most recent meeting was approximately two weeks ago. Two Highway Access Permits were granted with respect to a previous development proposal, including a signalized full movement intersection at the Cattle Creek crossing as well as a full movement access at the Wiggers/Sopris Restaurant property, but only if other accesses were eliminated. The latter intersection had no access across the RFTA corridor. Both of these access permits have lapsed. With respect to the most recent discussion between CDOT and Cattle Creek representatives, CDOT made it clear that the entire Cattle Creek intersection needed to be examined, including how to include the county roads on the east side of the highway. The current proposal for a second access, with a right -in right -out, was also discussed, and did not work for CDOT as currently proposed. Dan Roussin explained that the access permit process is really a two step process, with the permit being the first step, a conceptual approval only, followed by the second step with a notice to proceed. The latter is based upon actual engineer drawings showing exactly how the access will be built. The access permit phase reviews the traffic study and is based upon the traffic generated at full development. Any permit issued travels with the land. Dan Roussin made it clear that CDOT has no money available but is willing to work with all concerned to solve the challenges presented by the proposed development and these existing intersections. [1] Alisa Babler, the Permit Unit Engineer for the State of Colorado, explained that signals are based on spacing and distances. For the three mile stretch under discussion, she opined that the signalized intersections needed to be spaced one mile apart. Dan Roussin indicated that with respect to the County Road 154/Hardwick Bridge Intersection with Highway 82, the East Bank proposal as represented in the sketch plan will increase traffic at that intersection by more than 20%. Because the purposed subdivision does not directly access the state highway, CDOT will be asking the County to obtain an Access Permit for the increased traffic at the County Road 154/Hardwick Bridge/Highway 82 Intersection. Fred Jarman clarified that in those situations, the County historically has delegated that responsibility to the developer. There was further discussion about East Bank's efforts to try to re-route Orrison's traffic off of Highway 82. Dan Roussin explained that the access code discourages private access onto Highway 82 and that once private accesses have other access to public streets, the accesses to Highway 82 can be closed by CDOT. There was further discussion about possible improvements to that particular intersection as part of the East Bank development proposal. Dan Roussin indicated that CDOT distinguishes between minor developments and major developments, with a major development being any development that increases traffic at an intersection with a state highway by 20% or more. Incremental increases are not addressed in the access code and CDOT does not have answers on how to deal with incremental increases. He did indicate that state law makers are looking at that issue. With respect to the CMC intersection, County Road 114 and Highway 82, he indicated that this is one of the two major problem intersections in the County, with this particular intersection being perhaps the most difficult. He indicated that with the potential for growth on the east side of the highway, the bus stop, and the RFTA trail, personnel within CDOT have discussed in the past that the best solution would be a grade separated intersection. He indicated that this particular intersection will be such a significant cost to improve that it is probably best handled as a regional project. He strongly encouraged that the County address this through the TPR, either as part of the 2035 Plan or the 2040 Plan. In connection with potential solutions to address the issues for all these intersections, the following were mentioned: 1. Special improvement districts or other special districts. 2. Impact fees for transportation, but with caution that the amount of fees need to be realistic. 3. Pay back agreements such as are being used in Routt County. 4. Access control plan. Dan Roussin cautioned that this may not be the best solution for Highway 82 in this area because of the restriction on access already. Representatives from RFTA indicated that they were very willing to participate in further discussions because of their interest in addressing impacts created by the need for development. [2] An example was given that one development could generate the need for two additional buses at peak hours. Dan Roussin indicated that the funding opportunities for alternative transportation such as that offered by RFTA are much greater than opportunities for additional pavement. The County staff agreed to initiate regular meetings with CDOT and RFTA representatives. Once these meetings are organized and established, developers and other interested parties will be invited to attend, in order to address County staff, CDOT and RFTA representatives at the same time with respect to issues involving County Road and Highway Intersections.
