Box 1458 GLENWOOD SPRINGS, CoLORADo 81602-1458 September 12, 2007 Mr. Daniel Roussin Permitting Unit Manager Colorado Department of Transportation — Region 3 Traffic 222 S. 6th Street, Suite 100 Grand Junction, CO 81501 Subject: Access Permit Request Project: Spring Valley Ranch Dear Mr. Roussin: We have enclosed the following information related to an access permit application for the Spring Valley Ranch development: • Access permit application • Spring Valley Ranch — Phase 1 Traffic Impact Analysis, Felsburg Holt & Ullevig, August 2007. • Check for $300.00 to cover the access permit fee Spring Valley Ranch is located east of SH 82 in Garfield County. The only significant access to the development is Garfield County Road (CR) 114 which intersects SH 82 midway between Glenwood Springs and Carbondale. Based on our discussions in July 2007 with you and Garfield County, we are requesting an access permit for Phase 1. Spring Valley Ranch is a residential community which focuses on recreational activities. The preliminary PUD plan for the development was approved in 2005 and includes 577 residential dwellings, two 18 -hole golf courses and ancillary activities. Phase 1 involves 50 single family residents and one golf course. It is anticipated that Phase 1 will be ready for occupancy in late 2008. As such, the traffic and impacts to the intersection of SH 82/CR 114 are less than previously determined for the complete development, as discussed in the enclosed traffic study. As discussed with Dave Hattan of FHU, we are requesting your early attention to this request. The current PUD lapses on November 4, 2007, and Garfield County is requiring an approved access permit by that date. If your staff encounters any discrepancies in the application or traffic study, please call me or Dave Hattan [(303)- 721-1440], and the issue will be addressed immediately. Thank you for your assistance with this request. If you should have any questions please contact me.

As shown in Figure 1, the development is located approximately 5 miles east of SH 82 near the intersection of County Road (CR) 114 and CR 115. Spring Valley Ranch is a proposed residential community which focuses on recreational activities. Phase 1 of the development will include 50 single family detached cabins. Phase 1 will also include an 18 -hole golf course with several on- site amenities, a fire station, a sales office, and a metro district for municipal operations. At buildout the development will include 576 residential dwellings, two 18 -hole golf courses, a clubhouse, equestrian center, trailhead recreation center, and a village center that will contain commercial land uses. The traffic impacts of the buildout of the development are analyzed in Spring Valley Ranch Traffic Impact Analysis, Felsburg Holt & Ullevig, August 2005, which has the approved PUD. This current report analyzes Phase 1 of the proposed development and incorporates all the previous material, recent traffic volume counts, and updates the traffic forecasts to reflect the current Phase 1 proposal. It assesses the potential traffic impacts on adjacent roadways due to traffic generated by Phase 1 of Spring Valley Ranch and to identify roadway improvements. Specifically, this study analyzes traffic volumes forecasted to use the intersection of SH 82 and CR 114 as well as traffic operations on CR 114. For the purposes of this study, two future scenarios are considered: • Short Range Future — This scenario examines the traffic impacts at completion of Phase 1, assumed to be 2008. • Long Range Future — This scenario examines the traffic impacts associated with Phase 1 and the long range forecasted traffic volumes for 2027.

EXISTING CONDITIONS A. Roadway Network Figure 2 displays the current roadway laneage at the intersections of SH 82/CR 114 and CR 114/Frontage Road. CR 114 is a two-lane roadway which extends in a northeasterly direction from SH 82 to its intersection with CR 115 at the project site. There is a traffic signal at the SH 82/CR 114 intersection which is under the jurisdiction of the Colorado Department of Transportation (CDOT). There is a frontage road on the east side of SH 82 which closely parallels it and also intersects with CR 114. CR 114 is paved between SH 82 and the Colorado Mountain College campus, a distance of approximately 3.5 miles. CR 114 has a steep uphill grade in the eastbound direction for about the first mile east of the frontage road. The roadway surface is approximately 22 feet wide but varies between 20 and 24 feet. Beyond the college, the roadway has a gravel surface and is approximately 22 feet wide. There are no major bridges or ditch crossings along this stretch of road. The posted speed limit on CR 114 is 35 mph and 25 mph on sections with sharp curves. B. Existing Traffic Volumes Daily traffic counts were obtained for a one-week period in April 2006 on CR 114. More recent traffic counts could not be obtained, because at the time of this report, Colorado Mountain College was not in session. The 2006 counts were increased by a 2% growth rate to reflect 2007 existing conditions. This growth rate is consistent with CDOT's 20 year growth factor for SH 82. The resulting average weekday traffic volumes are shown on Figure 3. Existing peak hour turning movement traffic counts were also recorded at the intersections of SH 82/CR114 and CR 114/Frontage Road in April 2006 and were updated to reflect 2007 traffic volumes. The revised existing peak hour volumes are shown on Figure 4. Colorado Mountain College was in session when these counts were taken. The existing traffic count datasheets are located in Appendix A. C. Traffic Operations The primary focus of concerns about traffic operations is the intersection of SH 82/CR 114. This intersection is currently signalized, but traffic operations on the CR 114 approach to the intersection are complicated by the closely -spaced frontage road on the east side of SH 82. This second intersection has stop sign control on the frontage road approaches. The spacing between the edges of the pavement for the two roads is approximately 50 feet. Existing traffic operational conditions were analyzed at the intersections of SH 82/CR 114 and CR 114/Frontage Road using techniques documented in the Highway Capacity Manual (Transportation Research Board, 2000). The result of such an analysis is a level of service (LOS) rating. Level of service is a qualitative assessment of traffic flow based on the average stopped delay per vehicle at a controlled intersection. Levels of service are described by a letter designation ranging from "A" to "F", with LOS A representing essentially uninterrupted flow, while LOS F represents a breakdown of traffic flow with excessive congestion and delay. Unsignalized intersection analyses report a LOS rating for each movement which must yield to FELSBURG �i HOLT Si.

As shown on Figure 4, the intersection of SH 82 and CR 114 currently operates at LOS B during both peak hours. AH non -free flow movements at the unsignalized intersection of CR 114 and the frontage road operate at LOS C or better during the peak hours. LOS worksheets are provided in Appendix B. The LOS analyses were conducted using the computer program SYNCHRO. Occasional backups have been noted in the field for the northbound traffic on the frontage intersection. These are primarily caused by left turning traffic (to SH 82) on westbound CR 114 creating a continuous queue back from the signal at SH 82. This blocks the frontage road intersection and prevents frontage road traffic, desiring to turn northbound on SH 82, from making a right turn on red at the intersection. Much of this concern could be improved by placing signs reading "Do Not Block the Intersection" on the approaches to the frontage road intersection. If drivers heed these signs, it should keep most of the backups out of the intersection so it will be clear for vehicles turning right on red to go northbound on SH 82.

FUTURE CONDITIONS A. Proposed Land Uses Phase 1 of Spring Valley Ranch is proposed to have 50 single family homes, a golf course, a 2,500 square foot sales office, a fire station, and a metro district for municipal operations. B. Site Trip Generation For the majority of the proposed land uses, trip generation rates published in Trip Generation, Institute of Transportation Engineers (ITE), Seventh Edition 2003 were applied. To determine how many rounds of golf were played by members of the community, a survey was conducted. The survey showed that two-thirds of the rounds of golf were from members of the community at the buildout of the development. With the 50 single family homes constructed during Phase 1, it is estimated about 6 percent of the traffic generated by the golf course will be internal. Thus the remaining traffic is comprised of people living outside of the community. The trip generation for the sales office, fire station, and metro district were calculated using the Office land use. The previous study included alternative trip generations to analyze the development as a second -home community. Full-time residents were assumed for this analysis to be conservative. Table 1 summarizes the land uses and rates used for this study. Table 1.

As shown, it is anticipated that the site would generate about 1,100 trips per day on the external roadway network with approximately 80 occurring during the AM peak hour and 100 occurring during the PM peak hours. The approved PUD for the buildout of the site is forecasted to generate approximately 5,300 daily trips with 400 occurring during the AM peak hour and 500 during the PM peak hour. Table 2.

ULLEV10 Page 10 Spring Valley Ranch Phase 1 Traffic Impact Analysis C. Trip Distribution The site trip distribution estimates for development, shown in Figure 5, are based on the accessibility to major roadways, such as Interstate 70, and the developments location relative to existing developed areas in the Roaring Fork Valley, such as Glenwood Springs, Carbondale, and Aspen. It is expected that 67 percent of the site generated traffic would be oriented to and from the north on SH 82, and 33 percent would be oriented to and from the south on SH 82. D. Traffic Assignment The morning and evening peak hour site generated traffic volumes were assigned to the roadway network as shown in Figure 5. These traffic volumes represent the increased demand on the local roadway network as a direct result of the proposed development. Although both CR 114 and CR 115 provide access from Spring Valley Ranch to SH 82, it was assumed that 100% of the site generated traffic would use CR 114 because the roadway will be paved for use during Phase 1. This assumption is conservative, as it adds a maximum number of vehicle -trips to CR 114. Spring Valley Ranch would add about 1,100 vehicles per day (vpd) to CR 114. Daily volumes on SH 82 would increase approximately 750 north of CR 114 and 350 south of CR 114. E. Background Traffic Background traffic is the component of traffic volumes on the roadway network which are unrelated to the proposed development. Over the short range future (estimated to be 2008) background traffic on SH 82 is expected to grow at a rate of approximately 2% per year. This is consistent with the 20 year growth factor forecasted for SH 82 by CDOT, 1.4 which is approximately 2% per year. Background traffic was estimated on CR 114 based on traffic count data collected in April 2006. The calculated growth rate was less than 2% per year; therefore, CDOT's growth factor (2% per year) was used as a conservative estimate. Forecasts for the 2027 also utilized the aforementioned growth rates. Short range and long range forecasts of background traffic volumes at the study intersections are shown on Figures 6 and 9, respectively. C.

SH 82/CR114 Intersection — Short Range Future The site generated traffic (Figure 5) was added to the short range future background traffic (Figure 6) to represent total traffic volumes for the short range future. Figure 7 shows the total traffic volumes for the short range future buildout of Phase 1. Several laneage improvements are planned at the study intersections in order to accommodate the short range future traffic increases. These improvements would be constructed as an element of the cross section improvements to CR 114 (see later discussion) during the initial construction phase. These improvements would involve widening CR 114 on the approach to the intersection with SH 82. The first several hundred feet of CR 114 east of the frontage road should be widened to three lanes and striped to provide two westbound lanes so that right turns onto northbound SH 82 can be separated from through and left turning traffic. The separate right -turn lane allows traffic headed to Glenwood Springs (the predominate direction of travel) to turn right without waiting for westbound left and through traffic. An adequate acceleration lane on northbound SH 82 should be constructed for the right turning vehicles. This improvement will significantly improve intersection operations. Figure 8 shows the recommended laneage for the short range future. With the addition of the site generated traffic and the improvements recommended at these intersections, the signalized intersection of SH 82 and CR 114 is projected to operate at LOS B during the both the AM and PM peak hours. Figure 7 shows the anticipated levels of service for the study intersections. Short range future operational analysis worksheets are located in Appendix C. G. SH 82/CR 114 Intersection — Long Range Future Long range future (2027) total traffic volumes are shown on Figure 10. These volumes are the sum of the site generated traffic volume (Figures 5) and 2027 background traffic volumes (Figure 9). Background traffic at the intersection of SH 82 and CR 114 is forecasted to operate at LOS B in the morning and LOS D in the evening. No additional improvements are necessary to accommodate the anticipated long range traffic at this intersection. The intersection of SH 82 and CR 114 is forecasted to operate at LOS B during the AM peak hour and LOS D during the PM peak hour as shown on Figure 10. The above findings represent a worst case scenario which includes the following conditions: • The traffic counts that the future background volumes are based on were collected when Colorado Mountain College (CMC) was in session. • All of the site traffic will be served by CR 114. Long range future operational analysis worksheets are located in Appendix D. .

Roadway Capacity Analysis for CR 114 The Highway Capacity Manual separates two-lane highways into two categories, Class I and Class II highways, for determining the appropriate LOS. Class I highways are defined as highways with relatively high travel speeds and often serve long-distance trips. Class II highways are typically lower travel speeds and pass through rough terrain. For the purpose of this analysis, CR 114 was classified as a Class II two-lane highway. CR 114 is planned to have a climbing lane constructed in the later phases of this development. The two-lane highway capacity analysis for a Class II highway results in a flow rate (in vehicles per hour) relative to the level of service and the average speed. The level of service (LOS) ranges from "A" to "E" and is a qualitative assessment of the traffic flow based on the percent time delay. LOS A represents the highest quality of traffic service when motorists spend less than 40% of their time following another vehicle. LOS E represents traffic flow conditions for vehicles spending more than 85% of their time following another vehicle. Existing Roadway The existing capacity of CR 114 was determined based on information provided in the Highwav Capacity Manual, 2000. The capacity of a two-lane road is based on several variables including the grade, the length of the grade, the percentage of heavy vehicles, the lane and shoulder widths, and the percentage of the roadway where passing is allowed. The Highway Capacity Manual describes two methods for determining the capacity of a two- lane road. The first method is for general terrain and the second method is for sections of roadway where a specific grade is known. Separate analyses were performed for the rolling terrain segment of CR114 in the vicinity of the Colorado Mountain College and Spring Valley Ranch while the specific grade analysis was used for segment just east of SH 82 where the grade is steepest at a fairly consistent 7% grade. Based on the existing counts on CR 114, the peak hour occurs during the evening. Each lane is approximately 10 feet wide, with a two to four -foot shoulder on either side. Currently, CR 114 does not have any passing zones on this section. The existing peak hour volume on CR 114 is approximately 380 vehicles per hour (vph) during the evening peak hour. Traffic operates at LOS C on the steep segment of CR 114, and at LOS C higher up where the road is not as steep. Future Roadway Both the general terrain analysis and the specific grade analysis were used to determine the future capacity of CR 114. The general terrain analysis was used for the two-lane, rolling section of CR 114. The specific grade analysis was used for the improved two-lane section of CR 114, which has a grade of 7% over approximately 1.7 miles. Spring Valley Ranch is proposing to make improvements to CR 114 to accommodate forecasted increases in traffic including the addition of a climbing lane. Travel lanes are proposed to be 12 feet wide with four -foot shoulders on each side. CR 115 between CR 114 and Landis Creek . FELSBURG (4 HOLT & ULLEVIG Page 19 • • Spring Valley Ranch Phase 1 Traffic Impact Analysis provides access to the western portion of Spring Valley Ranch. This section of road will also be improved to the paved, two-lane cross section similar to that on CR 114. • General Terrain Analysis - The general terrain analysis was performed assuming rolling terrain with approximately 50 percent of the roadway allowing passing. This section of CR 114 is proposed to have a two-lane paved cross section with 12 foot lanes, and four -foot shoulders on each side. The general analysis (rolling terrain) for long range (2027) traffic volumes results in a forecast of LOS C. The maximum hourly capacity under these conditions is approximately 3,200 vph. Thus, the volume -to -capacity (v/c) ratio is 0.26. This shows that the future traffic is Tess than one-half of the maximum capacity. • Specific Grade Analysis - The capacity of the steep segment of CR 114 where the grade is 7% is approximately 1,700 vph, which is less than that of the rolling terrain above, as would be expected. The specific grade analysis determined that in the long range future (2027) traffic volumes operate at LOS C. The v/c ratios on CR 114 range from 0.27. Thus, the future volume represents less than one-third of the capacity of the roadway for either scenario. With the addition of a climbing lane the roadway is forecasted to operate at LOS A. . FELSBURG Ci HOLT ULLEVIG Page 20 Spring Valley Ranch Phase 1 Traffic Impact Analysis IV. SUMMARY AND CONCLUSIONS Spring Valley Ranch is a proposed residential development located in Garfield County, Colorado approximately 5 miles east of SH 82, near the intersection of CR 114 and CR 115. Phase 1 of Spring Valley Ranch will include 50 new single family detached dwelling units, an 18 -hole golf course, a fire station, sales office, and metro district. The approved PUD includes 576 residential dwellings, two 18 -hole golf courses, a clubhouse, equestrian center, trailhead recreation center, and a village center. The analysis of the proposed development site resulted in the following findings and recommendations: • The primary access to the development will be CR 114. Several improvements are recommended to this road east of its intersection with SH 82. The two travel lanes will be widened to 12 feet each with four -foot shoulders on each side. The unpaved portion of CR 114 approaching Spring Valley Ranch as well as CR 115 within the development will be paved with improved shoulders. Analysis of the long range future peak hour volumes results in a volume/capacity of 0.27 for CR 114 indicative of LOS C. • In the short range future the following improvements are needed at the intersection of SH 82 and CR 114: o Add a westbound to northbound right acceleration lane to separate right turning vehicles from the other movements at this intersection. With this improvement the intersection is projected to operate at level of service B during both the morning and evening peak hours. • The following improvements should be made near the intersection of CR 114 and the frontage road in the short range future: o Add a second westbound lane approaching the frontage road and SH 82. o Add a second lane for northbound traffic on the frontage road approaching CR 114. o Signs requiring motorists to not block the frontage road intersection should be added to the north, east, and south legs. With these improvements, all turning movements at this intersection will operate at LOS C or better during the peak hours. • In the long range future, no additional improvements would be required. The SH 82 / CR 114 intersection is anticipated to operate at LOS B during the AM peak hour and LOS D during the PM peak hour. All turning movements at the intersection of CR 114 and the frontage road are expected to operate at LOS C or better. OPFELSr3URG (d HOLT & ULLE\'IG Page 21 • • • Spring Valley Ranch Phase 1 Traffic Impact Analysis • SimTraffic simulations were run for all the short range and long range future scenarios. The simulations showed results similar to the LOS analysis. None of the scenarios showed significant queuing or delays with the exception of the long range future during the PM peak hour. Both the background and total scenarios showed northbound through queuing and southbound left queuing at the intersection of CR 114 and SH 82. It is recommended that the southbound left turn lane be extended to 285 feet at this intersection. Due to the delays at the signalized intersection, the frontage road also experiences delays.
