4 Northwestern Transportation Corridor Study Fiscal Year 2007 Funding Request Background The City of Grimes, in coordination with Dallas County, Polk County, Guthrie County, Audubon County, and the Cities of Ogden, Adel, Dallas Center, Redfield, Waukee, Panora, Guthrie Center, Altoona, Clive, Johnston, Urbandale and Polk City request funding to undertake a transportation planning study associated with the current and the projected traffic issues in the northwestern quadrant of the metropolitan area. In order to establish and protect the vital transportation corridors necessary for future development in Northwestern Polk and Eastern Dallas counties, a full feasibility and engineering study is required. To address transportation challenges in the NW quadrant, preliminary scoping work was completed along the Highway 141 corridor July 16, This study led to questions regarding the transportation system well beyond the scope of a single highway corridor (Figures 1-2 in the Supporting Documents Tab). Because of the need to plan regionally made apparent by the Highway 141 Scoping Study, the economic development organizations of Grimes, Johnston, Urbandale and Dallas County worked in concert with government and business representatives of the northwest quadrant to adopt on September 5, 2005 a value statement and shared vision that included the following: The economic development organizations value a shared vision of Regional Planning for Development affecting the communities of Grimes Johnston and Urbandale. The economic development organizations value a shared vision, strategy and action plan for Transportation Infrastructure Investment affecting each of the communities of Grimes Johnston and Urbandale. Primary focus will be major corridors and arterials, both existing and planned, as they influence the highway transportation system. These will include, however not be limited to: Interstate 35-80, Highway 141 and Highway 44. Opportunities for economic growth and expansion are on the near horizon in Northwestern Polk and Eastern Dallas counties. As indicated in Figures 3-4 in the Supporting Documents Tab, westward growth in this area is accelerating. This study is needed to enable communities, developers, property owners, and the governments that serve this area to make decisions regarding transportation infrastructure investments to facilitate and guide organized growth for the next 30 years. A key issue is the preservation of transportation corridors and the planning required for development of property adjacent to those corridors. Without a plan to preserve critical corridors, transportation opportunities could be lost, which will cause congestion and loss of planned growth and economic opportunities for the area. The implementation of this project represents true collaboration to plan for the future of the region. Feasibility Study In order to establish and protect the vital transportation corridors necessary for future development in Northwestern Polk and Eastern Dallas counties, a full feasibility and engineering study is required. The study will be designed to assist with decision making concerning the following issues. The extension of I-80 West from the intersection of I-80/35, Highway 141 and NW Urbandale Drive. Adopted March,

5 Options for connecting an I-80 Extension to I-80 West between Waukee and Adel. Options for reconfiguring traffic flow between I-80/35, Highway 44, Highway 141 and NW Urbandale Drive in order to facilitate traffic movement and development along Highway 141 North of the current intersections at NW Urbandale Drive and NW 54 th Ave. Options for connecting Highway 141 Southward to an I-80 Extension from points between Granger and Perry. Factors affecting decisions about the preservation of vital transportation corridors include the following: The need to relieve pressure on the I-35/80/235 System Interchange SW as development in the area continues and as commercial through-traffic increases. The pending development of new interchanges at NW 100 th Street and NW 26 th Street. The emergence of Highway 141 as an important transportation artery/connector and economic corridor for Northeastern Dallas and Northwestern Polk County. The limited feasibility of completing a high-speed corridor from a Northeast beltway westward beyond Polk City due to geographic and topographic constraints. The determination through a comprehensive transportation plan that infrastructure investments are coordinated such that short term investments do not preclude long term solutions Regional Planning Sub Committee of the MPO The Full Build Out Transportation Plan scoping document, dated January 11, 2006, (Figure 5, Supporting Documents) addresses these issues and establishes a more comprehensive geographic planning area in which to consider improvements to the transportation system. Planning will be based upon anticipated land use and estimated traffic loads. The Phase I study to be conducted by the MPO staff will identify the future regional transportation corridors and document the Full Build Out infrastructure requirements. Phase II will provide for more detailed documentation of the requirements and guide policy decisions concerning the priority of identified projects. The results of the Phase II study will also identify the preferred alignment of future transportation corridors, taking into account design components such as topography and environmental concerns. The Northwestern Transportation Corridor Study addresses Phase II of the Full Build-Out in the northwestern quadrant of the metropolitan area. Budget The cost of the Northwestern Transportation Corridor Phase II study is estimated to be $1 million. This amount is consistent with costs that have been associated with the development of plans for a Northeast Polk County beltway and related interchange justification studies. High Priority The communities located in Dallas County, Polk County, Guthrie County, and Audubon County including the Cities of Grimes, Ogden, Adel, Dallas Center, Redfield, Waukee, Panora, Guthrie Center, Altoona, Clive, Johnston, Urbandale and Polk City endorse funding to undertake this important project. This Full Build-Out transportation plan for the northwestern quadrant of the metropolitan area has been designated by the MPO as one of the high-priority surface transportation projects for FY07 federal funding. The economic development organizations representing Grimes, Johnston, Urbandale, and Dallas County have also formally endorsed the MPO s Regional Planning Committee concept of a Full Build-Out transportation plan. Reasons a large coalition of support has formed around this important project include: Current Partnership priority transportation projects, including interchanges on I-80/35 at NW 100 th Street and NW 26 th Street cannot proceed until a regional study is completed as per the U.S. DOT. Please see a letter to Iowa DOT engineer Scott Dockstader, Figure 6 in Supporting Documents. Adopted March,

6 Growth in the northwest quadrant of this metropolitan area has been explosive with increases in population of 76% ( ), property valuation of 97% ( ), in the three metropolitan cities of this area alone. See Figure 7, Supporting Documents. According to the IDOT traffic counts, traffic at the interchange of I-80/35 and Highway 141 and NW Urbandale Drive increased 41% from Areas of the intersection of I-80/35, Highway 141, and NW Urbandale Drive are rated a Level of Service E and F and will only worsen as growth in the NW quadrant continues unless plans are made to facilitate and accommodate growth. Beltway planning is happening throughout the metropolitan area. Highway 5/65 in the SE quadrant has been completed and beltways for the SW and NE quadrants are in the planning stages leaving a transportation hole in the NW quadrant. Please see Figures 8-9 in the Supporting Documents Tab. Transportation planning impacts a large area and must therefore represent interests of many people. Please see letters of support following the Letters of Support Tab. The endorsers of this project request federal funding in FY07 in the amount of $1 million such that Phase II of the MPO s Full Build-Out plan can commence upon completion of Phase I to determine new corridors and improved roadways as well as ensuring important high priority construction projects such as the interchanges at NW 100 th Street and NW 26 th Street can proceed without delay. The communities of Grimes, Ogden, Adel, Dallas Center, Redfield, Waukee, Panora, Guthrie Center, Altoona, Clive, Johnston, Urbandale and Polk City as well as Dallas County, Polk County, Guthrie County, and Audubon County respectfully request your support for this important project. Adopted March,

11 Northwestern Transportation Corridor Study - Fiscal Year 2007 Funding Request FULL BUILD OUT TRANSPORTATION PLAN SCOPING DOCUMENT January 11, 2006 The preparation of a regional Full Build Out Transportation Plan (FBOTP) will involve identification of transportation corridors which are key elements to the long range success of the Des Moines metropolitan area. A preliminary list of items to be considered was contained in the Transportation Planning Outline distributed on December 21, The FBOTP could be most effectively developed by performing the necessary work in two separate phases. The first phase would provide much of the critical information that was described in Exhibit A Scope of Work Regional Transportation Corridor Study proposed for the NW side of the metro area. However, the FBOTP Phase 1 study would be expanded to include similar work in the NE, SE, and SW quadrants of the metro area. Again, as a starting point for discussion purposes, the following is an outline of items that should be included in any discussions related to development of Phase 1 and Phase 2 of the FBOTP. It is anticipated that additional items will be added as input is received from the various governmental entities FBOTP PHASE 1 DMAMPO STAFF Identify planning boundary for the FBOTP (For this project, as aspects will require coordination with the Central Iowa Regional Transportation Planning Alliance (CIRTPA), the eight county/ten city group representing central Iowa since the CIRTPA has responsibility to the Iowa DOT for developing a long range transportation plan for their region need to be involved in selecting corridors that enter into their region.) Identify key stakeholder representatives within the planning boundary Identify land uses within the FBOTP Identify general locations for future regional transportation corridors (broad brush alignment with defined termini) Identify potential environmental/archeological impacts using available data bases for each identified corridor and broad brush alignment Generate planning level traffic models for scenario testing to determine Full Build Out (FBO) capacity needs. Scenario testing to include evaluation of Level of Service (LOS) on existing critical link roadways as well as future roadways. Identify current or planned transportation links/needs within the current MPO planning area o NE Beltway o NW Bypass o SW Bypass o I-35/80/235 System Interchanges (NE and SW) o IA 141/I-35/80 Interchange Page 1 of 3 Figure 5

12 Northwestern Transportation Corridor Study - Fiscal Year 2007 Funding Request o IA 44 o IA 141 o SE Diagonal o SW Diagonal/Connector o MLK Extension to I-35/80 o University Avenue Extension o All other State Highways which connect to the existing MPO Planning Area or are regional in nature that will affect the FBOTP. Through identification of future regional transportation corridors and FBO capacity needs, ultimate right-of-way (R/W) required can be established. Refinement of the alignment to allow for corridor preservation would occur during Phase 2 of the FBOTP. The target date for completion of Phase 1 would be 9 months from the authorization to start date. To meet this completion date, local units of government will need to provide anticipated future land use throughout the identified planning boundary. Trip generation based upon anticipated land use would provide estimated traffic loadings to roadway segments rather than socio-economic data. This is necessary because the planning period is for FBO conditions rather than a specific 25 year period. Page 2 of 3 Figure 5

13 Northwestern Transportation Corridor Study - Fiscal Year 2007 Funding Request Upon completion of Phase 1 by the DMAMPO staff, the individual transportation corridors identified as regionally significant can be prioritized for further study and refinement under Phase 2 of the FBOTP. In this second phase, each new corridor will be further refined to allow identification of a preferred alignment, taking into account existing topographic conditions and known environmental constraints that will impact construction of the roadway. As a minimum, the following items should be identified in Phase 2: FBOTP PHASE 2 CONSULTANT Governmental agency having jurisdiction and responsibility for corridor preservation Horizontal alignment and width of future corridor R/W Residential/business establishments likely to be displaced by the project Identification of access control needed to protect integrity of the corridor to maintain desired LOS at FBO Using most current socio-economic data, feasibility of staging of construction in accordance with the MPO Long Range Transportation Program (LRTP) Page 3 of 3 Figure 5
