Section 1 Executive Summary

Northwest Foothills Transportation Study Update July 213 Section 1. Executive Summary SECTION 1. EXECUTIVE SUMMARY The purpose of the Northwest Foothills Transportation Study Update (NWFTS Update) is to revise the roadway network and improvement recommendations of the Northwest Foothills Transportation Study which was adopted in 28 (28 NWFTS). Since its adoption, the following changes have occurred in and around the City of Eagle to bring about the need for this update: Update to the COMPASS Communities in Motion (CIM) Long Range Transportation Plan with a regional population forecast increase from 825, for 23 to 1,22, for 235 for Ada and Canyon Counties; Update of the Eagle Comprehensive Plan for the Eagle downtown area; ACHD Commission decision to not proceed with federal funding for the proposed Three Cities River Crossing roadway project, due to an estimated cost of over $8 million; The secondary crossing of Bureau of Land Management (BLM) property to serve the M3 Spring Valley development from Palmer Road was not approved by the BLM making Linder Road the only access from northwest Eagle; A Community Infrastructure District formed for M3 Spring Valley by City of Eagle; Adoption of the State Street Transit & Traffic Operational Plan (TTOP) by the City of Eagle, City of Boise, and ACHD; In addition to these regional actions, development plans in the foothills have changed for many of the tracts of privately-owned land. The City and ACHD also identified the need to tie the anticipated development to the regional horizon year of 235. The 28 NWFTS assumed all of the potential development in the foothills study area was fully completed (build-out), even though it could take well beyond on the 235 horizon year to accomplish. The change in development plans and the horizon year for estimating potential development in the northwest foothills result in the anticipated housing dropping from 24,261 units to 13,889 units and the anticipated employment dropping from 1,822 jobs to 4,579 jobs for this update. Figure 1 shows the updated roadway sizes and the anticipated type of control at key intersections. In addition, the roadways which increased or decreased in size from the 28 NWFTS are highlighted. Following are the key recommendations as part of this update: Eagle Road: Between Plaza Drive and Willow Creek Road, three lanes are recommended which will be refined pending the outcome of the Eagle Road/State Street Concept Study. Between Chinden Boulevard and SH 44, seven lanes are recommended in the long term, which is primarily due to regional growth and the removal of the Three Cities River Crossing. SH 44: Based on the TTOP recommendations and funding considerations, SH 44 is recommended to be five lanes plus high occupancy vehicle lanes (seven lanes total) between Glenwood Street and Eagle Road and five lanes between Eagle Road and SH 16. 2

Northwest Foothills Transportation Study Update July 213 Section 1. Executive Summary SH 55: Between Beacon Light Road and Avimor, five lanes is recommended with at-grade traffic signals at Beacon Light Road, Brookside and the two Avimor intersections. Grade separation may be required beyond 235 or in response to specific development requirements. Therefore right-of-way preservation for grade separations is recommended. Linder Road: Between Chinden Boulevard and SH 44, seven lanes are recommended in the very long term with the potential for incremental widening to five lanes in the medium term. This is primarily due to regional growth and the removal of the Three Cities River Crossing. Between Beacon Light Road and the M3 Spring Valley development, five lanes could be needed with the removal of the Palmer Road connection. Therefore, corridor preservation and/or construction of five lanes north of Beacon Light Road are recommended beyond 235. Beacon Light Road: Between Linder Road and SH 55, five lanes were identified as needed near the end of the study timeframe (around year 235). Corridor preservation for five lanes is therefore recommended. Willow Creek Road: A bypass of Willow Creek Road from Eagle Road to the proposed east-west foothills collector continues to be recommended as part of this plan due to the design and constraint of Willow Creek Road. The alignment of the bypass road will be dependent on future property development and topography. With this update, an implementation plan was developed. Following are the key findings of the implementation plan: Most of the short-term improvements on the existing transportation system are funded and planned for construction in the next five years. The two most significant short-term and medium-term improvements to existing roadways that remain unfunded are the widening of Chinden Boulevard (US 2/26) to five lanes from Eagle Road to SH 16 and widening SH 44 to five lanes between Linder Road and SH 16. The Idaho Transportation Department (ITD) has indicated that both improvements will likely be funded in the next five to ten years. All of the long-term widening needed on ITD roadways are currently unfunded including: o SH 55 widening to five lanes north of Beacon Light Road o SH 16 widening to five lanes (four lanes with median/left-turn lane), SH 44 to M3 Spring Valley o SH 44 widening for HOV lanes, Glenwood to SH 55 o Eagle Road widening to seven lanes, Chinden Boulevard to SH 44 Right-of-way preservation should be the focus for the following very long-term projects: o Beacon Light Road widening to five lanes (Linder Road to SH 55) o Linder Road widening to seven lanes (Chinden Boulevard to SH 44) o Linder Road widening to five lanes (Beacon Light Road to M3 Spring Valley) o SH 16 grade separations at, SH 44 Floating Feather, Beacon Light, and M3 Spring Valley o SH 55 widening to seven lanes from SH 44 to Beacon Light Road 5

Northwest Foothills Transportation Study Update July 213 Section 1. Executive Summary o Chinden Boulevard widening to seven lanes (six lanes with median/left-turn lane) from Cloverdale Road to SH 16. The roadway network and recommended projects should remain dynamic and responsive to development and changes to the adopted land-use and transportation plans. To accomplish this goal, a monitoring process should be agreed upon by the City and ACHD in an Inter-Governmental Agreement that identifies triggers for reviewing the improvements and how development within the surrounding area will be reviewed and coordinated with all parties. It is recommended that the land-use assumptions and recommendations used for this study be reviewed at least every five years and the study updated if significant changes to the future roadway network, land use assumptions, or adopted plans occur that could affect the need or appropriateness of the recommendations in this NWFTS Update. 6

Section 2 Introduction

Northwest Foothills Transportation Study Update July 213 Section 2. Introduction SECTION 2. INTRODUCTION The 28 Northwest Foothills Transportation Study (NWFTS) was developed to respond to the transportation infrastructure needs that are expected to occur due to development pressure in the northwest foothills. The area envisioned for this future development is illustrated in Figure 2. Over 85% of this area is privately owned and has the potential for some type of development or intensification of land uses. The purpose of this NWFTS Update is to analyze future land-use and traffic projections which reflect changes that have occurred since the adoption of the Northwest Foothills Transportation Study in 28 (28 NWFTS) as well as the background changes due to the horizon year moving out from 23 to 235. The result of this study update is an updated roadway network. A key element of this update is additional information to aid in the implementation of the plan. The 28 NWFTS, with this updated addendum, will continue to function as a policy guide and corridor preservation mechanism for improving the transportation system as development occurs in the Northwest Foothills area.

Northwest Foothills Transportation Study Update July 213 Section 2. Introduction CHANGES SINCE THE LAST STUDY The 28 NWFTS was adopted with the understanding that amendments to the Study could be required if land-use projections or other factors significantly changed that could impact the recommendations of the NWFTS. Since its adoption, the following changes have occurred in and around the City of Eagle: Update to the COMPASS Communities in Motion (CIM) Long Range Transportation Plan with a regional population forecast increase from 825, for 23 to 1,22, for 235 for Ada and Canyon Counties; Update of the Eagle Comprehensive Plan for the Eagle downtown area; ACHD Commission decision to not proceed with federal funding for the proposed Three Cities River Crossing roadway project, due to an estimated cost of over $8 million; The secondary crossing of Bureau of Land Management (BLM) property to serve the M3 Spring Valley development from Palmer Road was not approved by the BLM making Linder Road the only access from northwest Eagle; A Community Infrastructure District formed for M3 Spring Valley by City of Eagle; Adoption of the State Street Transit & Traffic Operational Plan (TTOP) by the City of Eagle, City of Boise, and ACHD; Significant changes in the types, intensity, and frequency of development proposals. 1

Section 3 Interagency and Public Involvement

Northwest Foothills Transportation Study Update July 213 Section 3. Interagency and Public Involvement SECTION 3. INTERAGENCY AND PUBLIC INVOLVEMENT Interagency coordination and public involvement occurred through meetings with the Project Management Team (PMT) and Project Steering Committee (SC). In addition, a public open house was conducted to gain input on the preliminary recommendations. PROJECT MANAGEMENT TEAM The PMT s role was to advise the consultant team on the technical elements of the project and make the final decisions regarding the overall project direction based on input from the consultant team, SC, and the public. Three PMT meetings were held between June and October 212. The SC provided a balanced representation of interests as well as a communication link with elected officials, citizens, and groups in the community. Members included agency staff representatives, representatives of local business groups, elected officials, and advocates of key interests, including transportation, social, and civic groups. Responsibilities of SC members included representing their constituents perspectives during group deliberations, communicating project progress to them, and working to develop recommendations in the development of projects that are consensus based. DEVELOPER MEETINGS Key land-owners and developers were contacted at the initiation of the NWFTS update in order to identify potential changes to the plans for their property. Meetings were held with key land-owners and developers including Avimor, M3 Companies, and Rick Thomas. The purpose of these meetings and contacts was to introduce the project and identify the likely development that may occur by 235. PUBLIC OPEN HOUSE One public open house was held from 5:3 to 7:3 p.m. on October 11, 212, to offer citizens the opportunity to review and comment on the preliminary plan updates. Approximately 6 people attended the public open house and 41 comment sheets were received. Summary information of the open house is included in the Appendix A. ACHD developed mailers, as shown in Figure 3, placed sandwich signs throughout the study area, and had Figure 3: Open House Announcement 13

Northwest Foothills Transportation Study Update July 213 Section 3. Interagency and Public Involvement advertisements in local papers. The mailers introduced the project, study area, and identified the date and location for the public open house. ACHD also maintained a project website which provided background information about the project and information presented at the public open house. Some of the general themes of the public comments included: Concerns about Beacon Light being planned for five lanes in the long term given the rural nature of the roadway and adjacent properties that exists today. Concerns about widening Linder Road. The need for more bicycle lanes throughout the area. Concerns about roundabouts as options to traffic signals. General changes to roadways in the area may be incompatible with rural atmosphere/quality of life in Eagle. The need to widen the State Highways. INFORMATIONAL SESSIONS Two informational presentations were held with the Eagle City Council and ACHD Commission during the project. These sessions were open to the public and provided the Eagle City Council and ACHD Commission with updates on the project, addressed any questions, and solicited input. The Eagle City Council, ACHD Commission, and Ada County Commission also held two joint meetings in March and June of 213, to discuss the study. 14

Section 4 Roadway Network and Land-use Estimates

Northwest Foothills Transportation Study Update July 213 Section 4. Roadway Networks & Land-Use Projection SECTION 4. ROADWAY NETWORKS & LAND-USE PROJECTION The roadway network and land-use estimates adopted as part of the 28 NWFTS were developed through an extensive process that included coordination with land owners and agencies responsible for planning, feasibility evaluation, and environmental evaluations. This update only addresses changes to the roadway network and land-uses that have occurred since the 28 NWFTS due to new proposals by land-owners, ACHD, or ITD. In some instances, developers have curtailed development plans or forgone development plans altogether. ROADWAY NETWORK The roadway network developed in the 28 NWFTS was based on a review of the land-use and topographical constraints that are present in the study area. Figure 4 shows the future roadway network recommended from the 28 study. New Connection to SH 16 Removal of Road Connection Figure 4: Recommended Roadway Network from 28 Study Since the 28 NWFTS, two changes in planned roadway connections have occurred. The first change is that the collector road connection from the M3 property to Palmer Road was not approved by the BLM. The second change is that M3 Companies has modified their plan to include a southern collector road connection to SH 16, north of Beacon Light Road. These changes are also identified in Figure 4. 17

Northwest Foothills Transportation Study Update July 213 Section 4. Roadway Networks & Land-Use Projection LAND-USE PROJECTIONS The Community Planning Association of Southwest Idaho (COMPASS) prepares the regional population and employment forecasts for the urban area, which includes Ada County and Canyon County. The population and employment forecasts used for the 28 NWFTS assumed a scenario in which much more significant development occurred within the study area than assumed in the COMPASS 23 (horizon year in 28) regional forecasts. The development estimates were based on a build-out of the proposed development areas in the northwest foothills. Build-out refers to completion of the total potential development of property within the study area, which is not expected to occur by our planning horizon year of 235. The advantage of using build-out forecasts for the development area is that on-site roadways can be built to their ultimate sizes and therefore be able to accommodate traffic growth beyond the adopted COMPASS Communities in Motion 235 Regional Long-Range Transportation Plan (COMPASS Plan). The disadvantage of using build-out forecasts for the NWFTS developments is that the impact of development traffic on the 235 background roadway network could be overestimated. Since this update is focused primarily on the changes to the external roadway network serving the northwest foothills in 235, it was determined that the most appropriate approach for this update was to base the growth estimates on how much development is expected to occur by 235, rather than assuming a build-out. This approach is consistent with the regional planning and provides a way to align this study with the currently adopted COMPASS Plan and the ACHD 212 Capital Improvement Plan (CIP). Many changes to development plans for properties in the northwest foothills have occurred since 28 that required a review of the land-use projections for key foothills developments. Meetings were held with key landowners to review their current plans and the anticipated timeframe they expect to reach their development targets for their properties. In addition, meetings with the City of Eagle and Ada County staff were held to discuss the current status of development approvals and land-use designations. The most significant changes relate to the development plans for the Connolly, Kastera, and Alpine Creek properties. Each has significantly decreased their planned development intensity or decided not to pursue development of a portion of their property. Table 1 shows the total projections that were assumed in the 28 NWFTS and the updated projections assumed for this update. Table 1: Comparison of Land Use for Foothills Development (28 NWFTS vs. Update) 28 NWFTS (Build-out) This Study Update (Year 235) Difference Homes 24,261 13,889-1,372 Jobs 1,822 4,579-6,243 As shown in Table 1, the housing and job estimates projected by 235 in the study area for this update are significantly lower than in the 28 NWFTS. 18

Northwest Foothills Transportation Study Update July 213 Section 4. Roadway Networks & Land-Use Projection While the estimated development in the foothills assumed for this update has significantly decreased, regional growth has increased since the 28 NWFTS. The 28 NWFTS estimated a population of approximately 825, for the metropolitan area (Ada and Canyon Counties combined) for the 23 horizon year. For 235, the estimated population is 1,22,. Therefore, while the expected growth in the foothills has been reduced, the forecasted traffic demands on the overall roadway system have increased due to the predicted increase in regional population between 23 and 235. FUTURE TRAFFIC OPERATIONS Future year traffic volume projections were developed by ACHD using the regional travel demand model with the population and employment forecasts for the northwest foothills study area updated to reflect the jobs and housing estimates described in the previous section. The traffic operations were analyzed in order to predict how the study area s transportation system will operate in the year 235. Table 2 provides a summary of the traffic operations analysis results for the key arterial roadways within the overall impact area studied in the 28 NWFTS. Based on the results shown in Table 2, the PMT and SC were engaged to review the resulting roadway sizes and provide input on the options for accommodating the future transportation needs on each roadway based on the 235 traffic projections. Two of the most significant increases in roadway sizes for ACHD roadways within the NWFTS study area were the need to increase Linder Road from five lanes to seven lanes between Chinden Boulevard and SH 44 and the need to increase Beacon Light Road to five lanes from two/three lanes between Linder Road and SH 55. The results for Linder Road and Beacon Light Road were consistent with the 212 CIP, which incorporated some of the major land-use transportation system changes since the 28 NWFTS including the increased regional growth for 235 and removal of the Three Cities River Crossing, which the ACHD Commission decided not pursue federal funding or include the project in the CIP because the estimated cost had increased to over $8 million. If built as originally planned, the Three Cities River Crossing would have connected Cloverdale Road and Five Mile Road from Chinden Boulevard to the SH 44/SH 55 intersection, providing an additional crossing of the Boise River and thus reducing demand on other arterials that cross the Boise River such as Linder Road and Eagle Road. Another factor in determining the updated roadway sizes was the adoption in 212 of the State Street Transit and Traffic Operational Plan (TTOP). The TTOP included an extensive study of the State Street and SH 44 corridor between downtown Boise and SH 16. The outcome of that study was an improvement plan for SH 44 that included the addition of high-occupancy-vehicle (HOV) lanes between Glenwood Street and Eagle Road (for a total of seven lanes) and widening to five lanes (also referred to as four lanes with a median in some documents) between Eagle Road and SH 16. This results in the same number of lanes east of Eagle Road, but a decrease from seven lanes to five lanes between Eagle Road and SH 16 within the 235 study horizon. Beyond 235, widening of SH 44 between Eagle Road and SH 16 to add HOV lanes (7 lanes total) is included in TTOP. 19

Northwest Foothills Transportation Study Update July 213 Section 4. Roadway Networks & Land-Use Projection Finally, the City of Eagle is currently working with ACHD to study Eagle Road from SH 44 through Downtown Eagle as part of a concept study for the Eagle Road/State Street intersection. That study has not been completed and will define the improvements in the vicinity of the Eagle Road/State Street intersection including circulation improvements to improve downtown connectivity. Based on the evaluation and review process described above and input from the public, City of Eagle, and ACHD Commission, the 235 roadway sizes and intersection control types were developed. Figure 5 shows the recommend roadway sizes and intersection control to meet the traffic demands generated by regional traffic growth and development in the northwest foothills. Also shown in Figure 5 are the sections of roadway that have changed since the 28 NWFTS. Table 3 lists the roadway recommendations that have changed since the 28 NWFTS, based on the recommended roadway network shown in Figure 5.

The expansion of Eagle Road (SH44 to Chinden) and Linder Road is primarily due to overall growth by 235 as compared to 23, but is also because the Three Cities River Crossing is no longer included in the regional transportation network. The expansion of Beacon Light Road between Linder and SH 55 was similarly impacted by the increase in the horizon year to 235, which pushed the traffic volume above the threshold for a three lane roadway. Eagle Road from Plaza Drive to State Street is included in Table 3 although the recommendation in this update is similar to the recommendation from the 28 NWFTS and will be refined as part of the Eagle Road/State Street Intersection Study. Eagle Road between Floating Feather Road and Willow Creek Road was changed to three lanes to accommodate the need for left-turn lanes and bicycle lanes. These corridors are discussed in greater detail in Section 5. 21

Northwest Foothills Transportation Study Update July 213 Section 4. Roadway Networks & Land-Use Projection DEVELOPMENT DRIVEN IMPROVEMENTS As part of the development of the updated roadway network shown in Figure 5, an evaluation was conducted to determine which improvements are due to the projected traffic growth from development in the northwest foothills. While most of the roadway improvements are the result of background traffic demand expected to occur by 235, many roadways and improvements are triggered by the development projected in the northwest foothills study area. Figure 6 highlights the roadway segments which need improvements as a result of the proposed foothills development. 24

Section 5 Key Corridors

Northwest Foothills Transportation Study Update July 213 Section 5. Key Corridors SECTION 5. KEY CORRIDORS As part of this update, some key corridors were identified as having unique characteristics that require additional background and discussion. This section includes a more detailed discussion of these corridors. EAGLE ROAD SH 44 to Beacon Light Road The traffic demand on Eagle Road north of SH 44 is identified to require five lanes from Plaza Drive to Beacon Light Road. There are two distinct areas within this section of Eagle Road. Figure 7 and Figure 8 show pictures for this section. The first is between Plaza Drive and State Street where the need for five lanes is consistent with the 28 NWFTS and the 212 ACHD CIP. Significant concern over widening this section of Eagle Road was expressed by many stakeholders and the public. As a result of this concern, the City of Eagle and ACHD have initiated a study of the Eagle Road/State Street intersection to determine the ultimate configuration of this section of Eagle Road and the intersection at State Street because the intersection configuration affects the roadway sizes. Figure 7: Eagle Road - North of Plaza Drive Figure 8: Eagle Road - South of Beacon Light Road Between State Street and Beacon Light Road, the additional growth in the NW foothills triggers the need for five lanes. Based on a review of the ability to widen to five lanes it was recommended that the impact would be too extensive to justify the widening, especially given the concerns expressed as part of the stakeholder and public involvement process. The impacts of widening would be extensive, ranging from businesses in downtown, to Eagle Elementary School, to residential homes, and creek and canal crossings. Therefore, the existing three-lane facility is recommended between State Street and Floating Feather and widening to three lanes is recommended between Floating Feather and Beacon Light Road to better accommodate pedestrians, bicycles, and turning vehicles. Chinden Blvd (US 2/26) to SH 44 Eagle Road, south of SH 44 is owned and maintained by the ITD and designated SH 55. ITD currently does not have plans for widening beyond the current five lanes. Based on the projected 235 traffic projections, a seven-lane access-controlled cross section is needed to accommodate the projected travel demand at LOS 28

Northwest Foothills Transportation Study Update July 213 Section 5. Key Corridors E or better on Eagle Road between Chinden Boulevard and SH 44. The 28 NWFTS recommended five lanes, however, with the increase in demand due to the 235 horizon year, and the decision to not fund the Three Cities River Crossing, the projected volume in 235 is approximately 23 percent greater than the 23 projection in the 28 NWFTS. While there is significant uncertainty in the likelihood of widening Eagle Road, it is recommended that ROW be preserved and widening be planned given the Three Cities River Crossing is no longer planned. WILLOW CREEK ROAD The existing Willow Creek Road is constrained due to the topography and existing residential development. The steep topography limits the ability to function at more than local road speeds, and the direct lot access and proximity to homes limits the ability to accommodate high levels of traffic. Figure 9 shows a picture along a typical section of Willow Creek. For these reasons, a new alignment is required if a connection north of Eagle Road is to be made to the future arterial portion of Willow Creek as identified in the NWFTS roadway network. The most likely location for a new connection is across the vacant land to the east which can be Figure 9: Willow Creek Road - Near Stillwell Drive characterized by large-parcel ownership (4+ acres). Topography will remain a factor in determining the alignment for a new connection as well as future land-use proposals by the property owners. Therefore, planning for the new connection to bypass the southern portion of Willow Creek should consider the following: Collaboration with the adjacent property owners to develop an alignment that minimizes negative property impacts and supports future land-use plans. Design of the roadway to minimize the grade and curvature in order to emphasize the route over the existing Willow Creek Road. Review the need to modify the south portion of Willow Creek Road to discourage through traffic. 29

Northwest Foothills Transportation Study Update July 213 Section 5. Key Corridors BEACON LIGHT ROAD The recommendation of this Study with the most varied opinions among those that offered input is widening of Beacon Light Road to five lanes. As shown in Figure 1, Beacon Light Road is considered by many residents to have a rural character today. The 28 NWFTS recommended widening to five lanes between Linder Road and SH 44 and three lanes between Linder Road and SH 55. The increase in traffic demand due to the additional five years of regional population and employment result in the need for five lanes between Linder Road and SH 55. The need for five lanes was originally identified in the adopted 212 CIP. Figure 1: Beacon Light Road - North of Eagle Road The public, SC, PMT, and Eagle City Council all identified the need to maintain the rural character of the Beacon Light Corridor. They also identified the need to ensure that Beacon Light Road is not widened solely due to ITD funding shortfalls for widening SH 44 beyond five lanes. These are all valid concerns given the very low traffic volumes (approximately 2,7 vehicles per day) on Beacon Light today. The challenge with determining the most appropriate improvements on Beacon Light Road in the long term is that a balance needs to be made between maintaining the rural character of Beacon Light Road, supporting the land-use planning goals of the City, and supporting and land uses along Beacon Light Road and the future growth projected in the northwest foothills and the region. Beacon Light Road is the only eastwest arterial north of SH 44 that will have long-term full-access connections to SH 16 and SH 55. Traffic is projected to significantly increase over the next 2 years. Figure 11 illustrates the general traffic growth projected on Beacon Light Road. As shown in Figure 11, the traffic growth on Beacon Light Road is projected to require widening beyond two or three lane capacity by approximately 23. The growth rate in traffic demand is expected to be high for the following reasons: Figure 11: Beacon Light Volume and Capacity Comparison Beacon Light Road provides the most direct route for northwest Eagle and Foothills Traffic to SH 55 and toward Boise. 3

Northwest Foothills Transportation Study Update July 213 Section 5. Key Corridors Much of the future residential growth in Eagle is in the rural areas of the City such as between Floating Feather and the foothills which is served by Beacon Light Road. Growth in Star and Emmett results in increased demand on Beacon Light Road for local trips to and from Eagle as well projected regional trips between SH 16 and SH 55. Avoidance of SH 44 due to future traffic congestion. If a lower traffic growth rate was assumed, widening Beacon Light Road may not be needed until Year 24, or further, but it is still shown as being needed at some point in the future. Therefore a balance needs to be maintained between impacting the land uses and livability along the corridor and preserving the ability to widen the corridor in the long term. One of the key concerns by citizens, the Eagle City Council, and ACHD Commission was Beacon Light Road being expanded to accommodate regional traffic that could be accommodated by the expansion of SH 44. To Figure 12: 235 Beacon Light Volume Projection vs. SH 44 Lanes a driver, getting to their destination is the purpose of their trip and there is little difference between the state highway system owned and maintained by ITD and the regional roadway system owned and maintained by ACHD. Therefore, if congestion occurs on SH 44, a driver may decide to use Beacon Light Road. Figure 12 shows a comparison of the traffic projections on Beacon Light Road at a location east of Linder Road assuming two sizes for SH 44. The first bar shows the projected traffic volume with SH 44 widened to five lanes (four lanes with a median/left-turn lane) per this plan and the TTOP. The second bar shows the result of widening SH 44 to seven lanes (6 lanes with a center median/left-turn lane). As shown in Figure 12, even with widening SH 44 to seven lanes, the projected volume on Beacon Light Road is still above what can be accommodated by only two or three lanes. In addition, the travel demand modeling identified that approximately thirty percent of the trips along Beacon Light Road traverse all or most of the corridor between SH 16 and SH 55. This indicates that Beacon Light Road is partially used by regional trips that could also be served by SH 44, but a majority of the trips (approximately 7 percent) utilize Beacon Light Road for only part of their trip. As a result of the concerns regarding widening Beacon Light Road, many comments were received regarding the need for ITD to widen the state highways in the area. ACHD and ITD coordinate regularly and both agencies have limited funding for construction and maintenance. Therefore, both agencies weigh the costs and impacts associated with meeting the future capacity needs with the goal of creating a system that meets the travel needs for the drivers. In the case of Beacon Light Road, ITD is planning for the expansion of SH 44 and SH 16 to five lanes (four lanes with a median in some locations). ACHD is planning for expansion 31

Northwest Foothills Transportation Study Update July 213 Section 5. Key Corridors of Beacon Light Road to five lanes (four lanes with a two-way left turn lane) through preservation of rightof-way. If SH 44 is widened by ITD to seven lanes, the need for widening of Beacon Light Road may be delayed, but would still be needed at some point in the very long-term future after 235. In summary, the traffic forecasts on Beacon Light Road identify the need for five lanes in the long-term, irrespective of how much ITD widens SH 44. The need is primarily due to regional growth and development within the City of Eagle. Even though the widening is projected to be needed, improvements and widening at key intersections can extend the timeframe for widening between intersections. It is also likely that the need for five lanes between intersections could be beyond 235, due to the variability that could occur with the projected growth. Therefore, a phased improvement approach is recommended on Beacon Light Road which is described below: Near Term: Monitor the key intersections at Linder Road, Eagle Road, SH 55, and SH16 to determine when a change in traffic control to a traffic signal or roundabout is needed. Continue preserving right-of way for five lanes. Medium Term: Based on the near-term monitoring, install traffic signals at SH 16 and SH 55 and signals or roundabouts at Linder Road and potentially Eagle Road. Long Term: Widen Beacon Light Road to five lanes between SH 16 and Linder Road and widen Beacon Light Road adjacent to key intersections to increase capacity at the intersections. Install signals or roundabouts at other public street intersections as warranted. Very Long Term: Widen the remainder of Beacon Light Road between Linder Road and SH 55 to five lanes. The purpose of this approach is to ensure corridor preservation for five lanes occurs but widening is not done until other options, such as expansion at key intersections, have been exhausted. SH 16 The section of SH 16 from SH 44 to Chaparral Road is two lanes with turn lanes at key intersections. The SH 16 Corridor Improvement Study Environmental Assessment completed by ITD in 24 identified widening SH 16 to four/five lanes with access management, some frontage roads, and traffic signals at key intersections. ITD has also completed the environmental study for SH 16 between I-84 and SH 44 which plans for traffic signals at key intersections in the near term when they meet warrants. The signals would ultimately be replaced by grade-separated interchanges in the long term. While grade separations are not currently planned north of SH 44, the vision for the corridor by ITD and projected traffic demands require grade separations at key intersections in the long-term. Therefore, signals are recommended at Floating Feather Road, Beacon Light Road, Aerie Way and Chaparral Road. In the long term, grade-separated interchanges are recommended at SH 44, Beacon Light Road, and Aerie Way. At that time Floating Feather Road is recommended as an overpass. 32

Northwest Foothills Transportation Study Update July 213 Section 5. Key Corridors Equest Lane was not envisioned in the roadway network to have full access to SH16, but has recently been proposed as an interim full-movement access to the M3 Spring Valley development. An interim signal may also be installed at the Equest Lane/Pollard Lane intersection, depending on the ultimate ITD permit conditions, but the signal will eventually be removed with the extension of Aerie Way to SH 16 and the widening of SH 16 to five lanes. At the time Aerie Way is extended to SH 16, or SH 16 is widened to five lanes, the signal would be removed and the intersection should be converted to right-in only or right-in, right-out only. LINDER ROAD There are two sections of Linder Road that received comments during the public involvement process. Chinden SH 44 Linder Road is currently two lanes for most of the section between Chinden Boulevard and SH 44. Figure 13 illustrates the existing configuration. Linder Road currently widens to five lanes at Chinden Boulevard and will soon widen to five lanes at SH 44 as part of an ongoing ACHD/ITD improvement project. The 212 CIP and this update identified the need for a seven-lane access-controlled cross section to accommodate the projected travel demand. This is greater than the five lanes recommended in the 28 NWFTS. This difference is primarily due to an increase in demand resulting from the 235 horizon year, Figure 13: Linder Road - North of Chinden Blvd (US 2/26) and the removal of the Three Cities River Crossing from the 235 roadway network. The result of these differences is that the projected volume in 235 is approximately 24 percent greater than the 23 projection in the 28 NWFTS. These thresholds do not account for the lack of signalized intersections between Chinden Boulevard and SH 44 which are the primary factor in determining the capacity. Therefore, the need for seven lanes is predominantly at the major intersections, which currently are Chinden Boulevard and SH 44. Since intersection improvements are identified at SH 44 and Chinden Boulevard, it is likely that seven lanes on the rural section of Linder Road will not be required unless significant development occurs between Chinden Boulevard and SH 44. But it is difficult to forecast where and how development will occur along the corridor. Given this uncertainty in land-use along this section of Linder Road, preservation for seven lanes is recommended, although interim widening to five lanes could be considered given the uncertainty of the need for widening between major intersections. 33

Northwest Foothills Transportation Study Update July 213 Section 5. Key Corridors Beacon Light Aerie Way The extension of Linder Road, shown in Figure 14, from its current terminus at W. Homer Road into the M3 Spring Valley development was recommended in the 28 NWFTS to be three lanes between Linder Road and Homer Road and two lanes north into the Spring Valley development. With the removal of the parallel connection to Palmer Road and the 235 demographic revisions, the 235 traffic projections show the need for a five-lane (four travel lanes with turn lanes at intersections) roadway section. Because a majority of the proposed alignment traverses BLM property and will not have intersections with other public streets, the capacity for accommodating through traffic is adequate with a single travel lane in each direction with turn lanes at minor intersections. At major intersections, five lanes will be needed. Linder Road Extension Figure 14: Linder Road Extension into M3 Spring Valley Development Based on the analysis, preservation for seven lanes on Linder Road between Chinden Boulevard and SH 44 and five lanes on Linder Road north of SH 44 is recommended. SH 55 BEACON LIGHT ROAD TO AVIMOR SH 55 between Beacon Light Road and Avimor was recommended in the 28 NWFTS to be a five-lane highway (four lanes with a median) with grade separated intersections at Brookside Lane, Avimor Drive, and the future northern access to Avimor. Currently, SH 55 has two lanes with turn lanes at key intersections and driveways as illustrated in Figure 15. The need for grade separated intersections was due to the large amount of development proposed for the Dry Creek Figure 15: SH 55 - North of Beacon Light Road Ranch planned community and build-out of the Avimor planned community. Neither of these developments is expected to be fully built-out by 235, resulting in less traffic demand SH 55. With the lower traffic demand, grade separations are not required through 235 although ITD may require grade separations at an earlier date based on permitting requirements for specific developments. Beyond 235, build-out of Avimor, Dry Creek Ranch, and other properties to the west, SH 55 may still require grade separations beyond 235. Therefore, future community planning should plan for the potential need for grade separations, and right-of-way should be preserved at the intersection locations. 34

Section 6 Implementation Strategy

Northwest Foothills Transportation Study Update July 213 Section 6. Implementation Strategy SECTION 6. IMPLEMENTATION STRATEGY This section describes the phased implementation strategy for achieving the long-term transportation vision for the Northwest Foothills Transportation Study (NWFTS). The purpose of the implementation strategy is to provide guidance on the implementation of improvements as traffic demand changes and new development occurs in the study area. Implementation of the recommendations of this update will be through the ACHD Capital Improvement Plan (CIP), ACHD Five Year Work Plan (FYWP), and development application and review processes. IMPLEMENTATION PLAN PROCESS The two primary aspects of the implementation plan for the NWFTS are the estimated timeframe of when each improvement is needed and a threshold trigger that can be monitored to identify when the need for an improvement may be approaching. The timeframe for each improvement was determined by reviewing four primary considerations. The first consideration was the timing of the improvement based on the projected growth in traffic. The second is how the improvement corresponds to other improvements planned in the area or on connecting roadways. The third is the importance of the improvement to support ongoing growth. The final consideration is whether the improvement can likely be funded and constructed within the proposed timeframe accounting for other improvements that also must be completed. The timing for each proposed improvement was separated into four categories: Short Term: Improvements that are planned to be constructed by ACHD, ITD or developers in the next 5 years. Medium Term: Improvements that are planned or estimated to be needed within the next 1 years, or are identified as part of the middle phases of developments. Long Term: Improvements that are planned or estimated to be needed within the next 1-2 years, or are identified as part of the later phases of the developments. Very Long Term: Improvements that are planned or estimated to be needed near, or potentially beyond, the end of the 235 study horizon. In addition to these timeframes, some roadways are in areas that may not develop at all by 235 and are needed solely to support a specific property or development. These roadways were left out of the implementation plan because they are solely to access certain development areas and are not needed for any other reason. The trigger for most improvements to existing roadways is based on the weekday peak hour directional traffic volumes. Traffic volumes are monitored by ACHD through traffic studies, traffic counts, and the periodic update of their CIP, and by ITD through permanent traffic counter stations and traffic studies. In instances where new roadways are solely associated with new development, they were identified as development-driven. In instances that improvements to existing roadways are significantly accelerated (moved up in time) by NWFTS developments, the improvement was identified as development- 38

Northwest Foothills Transportation Study Update July 213 Section 6. Implementation Strategy accelerated. For development-driven and development-accelerated improvements, an estimate of development units is provided based on the traffic analysis conducted for this study and traffic information provided in the studies for specific developments. The development unit trigger is only intended to be a guide and the final unit threshold will be determined as part of the development approval process through the City, ACHD, and ITD. Finally, potential funding sources were identified for each improvement. For the purpose of this study, the financing options were limited to the following: ACHD CIP: Applicable for improvements to ACHD arterials that are listed on the CIP. Note that the CIP does not guarantee funding but provides a funding mechanism. ACHD Unfunded: Applicable for improvements to ACHD arterials that are not included in the CIP but are shown to be needed. Extraordinary Impact Fee (EIF): Potentially applicable for construction on the arterial roadway system if ACHD were to work with developments in a particular area to establish an EIF. Community Infrastructure District (CID): Potentially applicable funding source for development-driven/accelerated improvements that qualify and that enter an agreement with the City and roadway agency. ITD Funded: Improvements on the state highway system that are included in the ITD 5-Year Statewide Transportation Improvement Program (STIP) ITD Unfunded: Improvements on the state highway system that are not fully funded at this time but are shown to be needed. Private: Applicable to improvements that are development-driven or developmentaccelerated. Following is a summary of the general findings and recommendations of the implementation plan: Most of the short-term improvements on the existing transportation system are funded and planned for construction in the next five years. The two most significant improvements short-term and medium-term improvements to existing roadways that remain unfunded are the widening of Chinden Boulevard (US 2/26) to five lanes from Eagle Road to SH 16 and widening SH 44 to five lanes between Linder Road and SH 16. ITD has indicated that both improvements will likely be funded in the next five to ten years. All of the long-term widening needed on ITD roadways are currently unfunded including: o SH 55 widening to five lanes north of Beacon Light Road o SH 16 widening to five lanes, SH 44 to M3 Spring Valley o SH 44 widening for HOV lanes, Glenwood to SH 55 o Eagle Road widening to seven lanes, Chinden Boulevard to SH 44 Significant improvements are needed in the very-long-term, which include the grade separations on SH 16, widening SH 55 to seven lanes between SH 44 and Beacon Light Road, and widening Chinden Boulevard to seven lanes between Cloverdale Road and SH 16. 39

Northwest Foothills Transportation Study Update July 213 Section 6. Implementation Strategy Right-of-way preservation should be the focus for the following very long-term projects: o Beacon Light Road widening to five lanes (Linder Road to SH 55) o Linder Road widening to seven lanes (Chinden Boulevard to SH 44) o Linder Road widening to five lanes (Beacon Light Road to M3 Spring Valley) o SH 16 grade separations at SH 44, Floating Feather, Beacon Light, and M3 Spring Valley o SH 55 widening to seven lanes from SH 44 to Beacon Light Road o Chinden Boulevard widening to seven lanes from Cloverdale Road to SH 16. Table 4 summarizes the recommended improvements for all roadways and intersections included in the Northwest Foothills Transportation Study Update. The table also includes the triggers and possible funding source for the improvements. Furthermore, the improvements are numbered and organized into four categories: Short-Term (S), Medium-Term (M), Long-Term (L), and Very Long-Term (VL). The improvements are also shown in Figure 16, Figure 17, Figure 18, and Figure 19, respectively. In some instances, roadways or intersections may require a different level of improvement for two different time horizons. In these instances, the improvements could be phased over the two time horizons or the longer-term improvement could be constructed upfront. For roadway sections with more than one improvement option, both levels of improvement are listed in Table 4 under the earliest timeframe. 4

Northwest Foothills Transportation Plan Update July 213 Section 6. Implementation Strategy IMPLEMENTATION PLAN ELEMENTS A key aspect of the implementation strategy is the process to ensure project development occurs for the study area when needed. This includes coordinating with private developers, review and updating of the Capital Improvements Plan / Five-Year Work Plan, identifying funding sources, and monitoring for future updates to the NWFTS. Private Development Actions Private development will be the key driver for improvements north of Beacon Light Road as well as a contributor to improvements throughout the study area. Both ACHD and the City of Eagle coordinate regularly. As development applications occur in the northwest foothills, ACHD and the City of Eagle should coordinate in reviewing these applications and the necessary transportation infrastructure that is necessary to support each application. The implementation strategy provides a framework for new development and land-use applications to understand the transportation needs and improvements in the study area. Based on this framework, a more detailed strategy will be developed for each application and validated with the traffic impact study that is required as part of most applications. CID Funding Since adoption of the 28 NWFTS, Community Infrastructure District (CID) funding has been approved by the City of Eagle for the M3 Spring Valley development. CID funding can be used for any roadway improvement project that is required for development, whether it is within the development or off-site on the existing transportation system. Based on input from SC and City of Eagle, the most likely roadway improvements for CID funding will be the public roadways within the northwest foothills that will serve the developments and improvements to the primary transportation corridors that directly serve the developments. Some of the existing primary transportation corridors serving the NWFTS developments include: Linder Road Beacon Light to Aerie Way SH 16 SH 44 to Chaparral Road SH 55 Beacon Light to Avimor Drive Willow Creek Road Eagle Road to Aerie Way Another aspect of CID funding is that it is best suited to fund improvements after some development is already completed. The primary transportation corridors listed above generally need improvement in the medium and long-term and therefore could be good candidates for CID funding. 49

Northwest Foothills Transportation Study Update July 213 Section 6. Implementation Strategy Corridor Preservation The most uncertain part of any implementation plan focused on future needs is the timing of projects. This is because development and background growth can be difficult to predict. For this reason, corridor preservation is the most important aspect of the implementation strategy. As land-use applications are made, ACHD and the City should ensure that adequate right-of-way is preserved such that future improvements can be made, even if they are far into the future. Without preservation, some improvements may not be possible which can have a ripple effect throughout the entire plan as projects on other roadways may need to be expanded or changed. Monitoring Process The purpose of this study is to ensure that adequate safety and capacity is provided for highway users throughout the year 235 horizon. While general monitoring thresholds are included within this update to assist agencies in reviewing the need and timing of phased implementation, the study and roadway network plan should remain dynamic and responsive to development and changes to the adopted land-use and transportation plans. To accomplish this goal, a monitoring process should be agreed upon by the City and ACHD in an Inter-Governmental Agreement that identifies triggers for reviewing the corridor plan and how development within the surrounding area will be reviewed and coordinated with all parties. It is recommended that the land-use assumptions and recommendations of this study be reviewed at least every five years and the study updated if significant changes have occurred. 5
