Overview Dakota County, in partnership with Apple Valley, Eagan, Farmington, Inver Grove Heights, Lakeville, Rosemount, Dakota County townships, Scott County, the Metropolitan Council and the Minnesota Department of Transportation completed a Principal Arterial Study of selected County highways. Highways designated as principal arterials are designed to provide mobility and safe, time-efficient travel over long distances for substantial traffic volumes. Technical guidance and principal arterial characteristics such as traffic volume, freight, transit and connectivity were considered in the evaluation. The study evaluated several existing/future highway corridors (non-freeway) and identified segments that best serve the public now or in the future with principal arterial classifications. Public meetings, geographically spread throughout the County, were held to gather public feedback. The study recommends designating County State Aid Highway (CSAH) 70 (210th/215th Street) and CSAH 23 (Cedar Avenue- within Lakeville) as principal arterials. Other highways (outside Lakeville) are also recommended as future principal arterials. Study results provide guidance and support in managing the corridors and developing strategic, long-term planning and capital improvement decisions. Primary Issues to Consider • Dakota County requests a resolution recognizing the study process, including principal arterial recommendations. Study results will be incorporated into the Dakota County Transportation Plan, pending County Board approval. The Metropolitan Council must approve the County’s request to designate CSAH 23 and CSAH 70 as principal arterials.

The Study provides priorities and recommendations for future principal arterial (PA) highways. Executive Summary The transportation system of Dakota County, Minnesota, is built around a framework of Principal Arterial (PA) highways, which are well established to the north – for example, the major river crossings (I-35W, I-35E, I-494, US 52, US 61, MN 77, and MN 55). However, possible gaps in the PA system are apparent to the south and east. Figure ES-1 illustrates this, showing which highways are existing principal arterials (red lines) with relative 2015 daily traffic volumes on all highways (line weights). Designated PA highways include freeways and other highways planned and managed to provide time- efficient and safe travel over long distances for many motorists. These “backbone” highways emphasize mobility over access. PA highways help connect the region with the other areas in the state, carry the major portion of trips to/from activity centers, and serve the majority of through movements. The Dakota County PA Study focused on planning for selected highways, all of which are not freeways and are not intended to become freeways in the future. The key outcomes are priorities for near-term designation of new PA segments and identification of other segments as recommended future PA highways. Need for the Study Dakota County Growth and Principal Arterial Spacing Dakota County’s highway system has been established to follow the area’s growth and development, which continues. US Census data and State Demographer forecasts indicate the County gained 42,648 residents from 2000 to 2010 (a 12 percent increase). The County’s population, at 398,552 persons in 2010, is expected to exceed 500,000 persons by 2035. Technical guidance for spacing of PA highways encourages a network spaced logically within the region: 2-6 miles apart in developed suburban growth areas 6-12 miles apart in rural areas With reference to Figure ES-1, Dakota County’s existing system includes no east-west PA highways south of County Highway (CH) 42, a distance of about 20 miles. Similarly, the gaps between north-south PAs include 15-20 miles from I-35 to US 52 and about 10 miles from US 52 to MN 316. The PA Study looked at the importance of selected highways based on their potential to fit applicable guidance; specifically: County Highway 63 (Argenta Trail) MN Highway 3 MN Highway 149 County Highway 28 (Yankee Doodle Rd.) County Highway 23 (Cedar Ave.) County Highway 70 MN Highway 50 County Highway 86 Intentionally Blank (This PDF is set up for 2-sided printing with blank pages inserted where appropriate.) !"b$!"b$ %&f( %&d(?éA@ )s ?ÕA@ ?ÕA@ ?§A@ ?§A@ ?úA@ ?±A@ ?tA@ !"`$ %&c( )s )s ?uA@ ?§A@ GyWX GwWX GjWX GhWX G¹WX G£WX GâWX ?cA@ ?èA@ G¢WX ?ØA@ ?ØA@ )p %&f( %&c( %&d( !"`$ )p ?éA@ ?ØA@?éA@ )p ?ÙA@ G¤WX?±A@ G¥WX GÌWX G¼WX SÎ GÎWX G²WX GgWX G±WX GªWX GÑWX GÑWX G¸WX GàWX G¹WX ?¹A@ SÈ GÉWX GÐWX WashingtonRamseyHennepinRamseyScott Rice GoodhueRiceWisconsin UMore Park Legend !IExisting Arterial Roads Principal Arterial Minor Arterial 2015 AADT < 5000 5000 - 10000 10000 - 20000 20000 - 30000 30000 + Planned Roads Planned Roads 0 5MilesSource: Met Council, MnGeo, Dakota County, MnDOT Study Corridor Park UMore Park ##Spacing (Miles) Principal Arterial Corridor Volumes Map Document: \\metrosouth1\gis\DACO\T44114295\ESRI\Maps\Overview_Regional\Overview_Volume_85x11P.mxd | Date Saved: 9/19/2017 10:55:42 AM Figure ES­1 Source: MnDOT, Dakota Co, Met.

But it does identify a few segments proposed for near-term PA designation (in the coming months or years). These corridors, highlighted on Figure ES-1, were identified by Dakota County as the best candidates for future PA designation. All of them exhibit good north-south or east-west continuity and provide connections to important destinations. A one-mile segment of CH 28 (Yankee Doodle Road) was also identified as a possible connection in a future PA system based on its links to CH 63 and MN 149. Study Objectives The Study’s primary objectives were to evaluate how the above-noted highways are used and the features they exhibit compared with PA highway characteristics. Other objectives included documenting context for the highways and providing guidance to help Dakota County and its partners plan for both regional and local highway system priorities. The intent of the study was not to identify corridors that require major infrastructure investment or to prioritize improvement needs, but to identify corridors that will be required to provide a PA function for the public either now or in the future. This will allow Dakota County, MnDOT, and the cities to plan for and manage the corridors and supporting road network over time and make appropriate investment to support the PA function at the time they are needed. Importantly, the Study does not complete a formal decision-making process for designation of new PA highway segments. But it does provide supporting data and guidance on next steps, including identification of a few segments proposed for near-term PA designation (in the coming months or few years). The Study may also serve as a reference for future discussions of highway jurisdictional roles— county vs. state highways. While setting priorities for highway system funding was also not a primary objective, designated PA highways have greater potential for National Highway System (NHS) preservation funding and for other federal and state funding programs. Study Scope, Process, and Partners All highways addressed in the Study provide continuity over long distances, serving many trips, commuters, and population or employment destinations. Initially, dozens of parameters were considered based on FHWA, MnDOT, Metropolitan Council, and Dakota County guidance. But certain characteristics were found to be most relevant in building the Study’s technical framework: Decision characteristics: Does the highway function like a PA? Decision characteristics concern the suitability of corridors to be future PA highways. The key decision characteristics included system spacing, traffic volumes, system connectivity, capacity role in system, and role in carrying freight. Timing characteristics: Is the highway ready to be a PA? Timing characteristics are those affecting the “readiness” of the corridor and often provide a basis for additional corridor planning. The key timing characteristics included access spacing, posted speed, high-capacity intersections, transit (in urban areas), right-of-way, and absence of parking. ` FINAL REPORT June 2018 Page ES-3 Dakota County invited and encouraged participation from a full range of relevant partners, specifically: MnDOT Metropolitan Council Dakota County Scott County Cities of Apple Valley, Eagan, Farmington, Inver Grove Heights, Lakeville, and Rosemount Representatives of the County’s 13 townships and rural centers (under 5,000 residents each) Representatives of these agencies participated in periodic Study Management Team (SMT) meetings. The same agencies, as well as other invited stakeholders, were also involved in a series of four subarea outreach meetings, which were held from late November 2017 into January 2018. Study Results and Conclusions/Recommendations Figure ES-2 presents the PA Study’s overall conclusions and recommendations. The information below briefly notes how Study conclusions and recommendations were reached, including consideration of input from outreach meetings. More details are provided in the full Final Report A. North Subarea – Eagan, Inver Grove Heights, and Rosemount MN 149, CH 63, CH 28, and MN 3 This is a developed urban part of Dakota County and exhibits some of the highest traffic volumes observed on PA Study highways. Discussions of this area noted close spacing between MN 149, CH 63 (a planned new connection to I-494), and close spacing for MN 3 to the north and constraints from development on MN 3 in downtown Rosemount. Considering these and other unique characteristics, a one-mile segment of CH 28 connecting CH 63 and MN 149 was added to the Study. Conclusions. Because of close spacing and roles in serving future traffic, the northern-most segments of MN 149 and MN 3 are not recommended as future PA highways. All other segments in the North Subarea are recommended as future PA highway routes, but not for near-term designation. CH 63 is noteworthy in the Study as a special case because it is a planned, partially completed, new corridor with right-of-way reserved for a future access-managed arterial connecting to I-494. West Subarea – Apple Valley and Lakeville CH 23 and CH 70 Like the North, the West Subarea is mostly developed and exhibits some of the highest traffic volumes observed on PA Study highways. Discussions for this area focused on the current and future roles of CH 23 (north-south) and CH 70 (east-west), including the proposed future eastward extension of CH 70 to Farmington and to MN 50 and US 61 (see more below in the East Subarea section). Conclusions. The Study found that CH 23 and CH 70 exhibit regional importance now and in the future; additionally, these links have available rights-of-way, good access spacing/management, and high posted speeds. The two segments, which connect to each other and to I-35 on the west, are recommended for near-term designation as PA highways (Figure ES-2). In the coming months or few years, Dakota County will work with the two cities, as well as the Metropolitan Council and MnDOT, to officially determine a functional classification change. The one other segment in the West Subarea (CH 70 west of I-35) is recommended as a future PA highway route, but not for near-term designation.

Transitional land use is an important characteristic, with both urban and rural areas observed. As noted for the West Subarea above, the future regional importance of the CH 70 – CH 50 - MN 50 - US 61 corridor is also a consideration to the east. The Study noted the need to manage highway access and mobility through the small but growing communities to the east – Hampton, New Trier, and Miesville. Conclusions. The East Subarea’s highway segments reflect PA characteristics and all are recommended as future PA highway routes, but not for near-term designation. As noted for both the West and East Subareas, the regional importance of this multi-jurisdictional corridor for future mobility, and planning for future demands, should be considered in future studies. South Subarea – Southern Lakeville/Farmington and Rural Townships to South CH 23, MN 3, and CH 86 The South Subarea is rural, but includes future growth areas. With few local traffic generators, the highways in the South are often used for through trips and provide important connections to jobs and commerce. The system issues for this subarea include connectivity to the north, to I-35, to Northfield, and to Rochester via US 52, an existing PA. Discussions of this subarea noted that CH 86 has some limited rights-of-way and no interchange with I-35. The close spacing of parallel segments of MN 3 and CH 23 was also noted. Conclusions. The segments in the South Subarea typically fit the characteristics of PA highways. However, the spacing is close between the southern-most portions of CH 23 and MN 3, and relative importance in connecting to Northfield is an issue as noted above. Therefore, MN 3 is recommended as a future PA segment connecting to Northfield; CH 23 south of CH 86 is not recommended as a future PA. All other segments of CH 23, MN 3, and CH 86 are recommended as future PA highway routes, but not for near-term designation based on timing/readiness issues. Next Steps The Dakota County PA Study concludes with the above-noted conclusions and recommendations, including the proposed near-term official designation of CH 70 east of I-35 and CH 23 north of CH 70 as PA highways (West Subarea). Figure ES-3 summarizes next steps, which will include noting recommendations in the County’s 2040 Transportation Plan. The proposed near- term designations will be formally addressed in the coming months or years with the Metropolitan Council and MnDOT. This Study’s results, which include several recommendations to manage all of the recommended future PA highways, will be updated periodically and reflected in transportation plans. FIGURE ES-3. SUMMARY OF N EXT STEPS FINAL REPORT June 2018 Page 1 The Study focused on planning for selected highways, all of which are not freeways and are not intended to become freeways in the future. The Study provides priorities and recommendations for future principal arterial (PA) highways. 1 Introduction and Need for Study The transportation system of Dakota County, Minnesota, is built around a framework of Principal Arterial (PA) highways, which are well established to the north – for example, the major river crossings (I-35W, I-35E, I-494, US 52, US 61, MN 77, and MN 55). However, possible gaps in the PA system are apparent to the south and east. Designated PA highways include freeways and other highways planned and managed to provide time-efficient and safe travel over long distances for many motorists. These “backbone” highways emphasize mobility over access, as illustrated in the chart noting functional classifications. In the functional classification framework, PA highways: Connect the region with the other areas in the state or connect metro centers to regional business concentrations (Dakota County, 2012; 2030 Transportation Plan). Carry the major portion of trips entering and leaving an activity center, as well as the majority of through movements (FHWA, 2013; Functional Class Concepts, Criterial and Procedures). The Dakota County PA Study addressed the need to establish sustainable and locally supported visions along corridors which could be candidates for designation as new PA highways. The Study focused on planning for selected highways, all of which are not freeways and are not intended to become freeways in the future. The key outcomes are priorities for near-term designation of new PA segments and identification of other segments as recommended future PA highways. 1.1 Dakota County Growth and Principal Arterial Spacing Dakota County’s highway system has been established to follow the area’s growth and development. Figure 1 illustrates this growth pattern, both historically (since 2010) and forecasted. Not surprisingly, the County’s greatest levels of growth are seen within the major suburbs, with moderate growth occurring in townships to the south and east. Forecasts indicate that strong growth will continue, even without proactive efforts to review the highway network. US Census data and State Demographer forecasts indicate the County gained 42,648 residents from 2000 to 2010 (a 12 percent increase). The County’s population, at 398,552 persons in 2010, is expected to exceed 500,000 persons by 2035. The County’s historic and forecasted population growth rate exceeds one percent per year and is also reflected in increased employment, economic activity, and travel demand.

Figure 2 provides a regional perspective, showing Dakota County’s position in the region relative to other existing PA highways and future PA highways identified by Scott County. Figure 2 also emphasizes the study corridors selected for analysis in the PA Study, based on system spacing and other observations. The eight “study corridor” highways show are: County Highway 63 (Argenta Trail) MN Highway 3 MN Highway 149 County Highway 28 (Yankee Doodle Rd.) County Highway 23 (Cedar Ave.) County Highway 70 MN Highway 50 / US 61 County Highway 86 These corridors were identified by Dakota County as the best candidates for possible PA designation considering travel patterns, the service to destinations provided by each route, and desirable highway system spacing. Figure 3 illustrates the current travel demand pattern, including existing principal arterials (red lines) with relative 2015 daily traffic volumes on all highways (line weights). Technical guidance for spacing of PA highways encourages a network spaced logically within the region: 2-6 miles apart in developed suburban growth areas 6-12 miles apart in rural areas With reference to Figure 4, Dakota County’s existing system includes no east-west PAs south of County Highway (CH) 42, a distance of about 20 miles. Similarly, the gaps between north-south PAs include 15- 20 miles from I-35 to US 52 and about 10 miles from US 52 to MN 316. Even in the more rural parts of the County, these gaps may exceed desirable spacing – especially considering these are future growth areas. All of the study corridor highways have roles in providing good north-south or east-west continuity and provide connections to important destinations. Additionally, the one-mile segment of CH 28 (Yankee Doodle Road) was also identified as a possible PA connection based on its links to CH 63 and MN 149. 1.2 Study Objectives The Study’s primary objectives were to evaluate how the above-noted highways are used and the features they exhibit compared with PA highway characteristics. As described in more detail below, PA characteristics were identified based on guidance from the Federal Highway Administration (FHWA), Dakota County, and the Metropolitan Council.

But it does identify a few segments proposed for formal review and near-term PA designation (in the coming months or years). regional and local highway system priorities. Perhaps most important, completing this Study will help prevent the consequences of not planning ahead, as listed in the text box. Of course, growth will continue, even without proactive planning, as evident in new development along the highways addressed in this Study. But with a coordinated plan, the highway system is more likely to be designed to meet mobility and safety objectives for Dakota County’s many developing areas. The intent of the study was not to identify corridors that require major infrastructure investment or to prioritize improvement needs, but to identify corridors that will be required to provide a PA function for the public either now or in the future. This will allow Dakota County, MnDOT, and the cities to plan for and manage the corridors and supporting road network over time and make appropriate investment to support the PA function at the time they are needed. Importantly, the Study does not complete a formal decision-making process for designation of new PA highway segments. But it does provide supporting data and guidance on next steps, including identification of a few segments proposed for formal review and near-term PA designation (in the coming months or years). The Study’s full Final Report serves as a reference for discussions of highway jurisdictional roles—considering local governments, Dakota County, the Minnesota Department of Transportation (MnDOT), and the Metropolitan Council. In this context, the Study provides information about the possible regional importance of several highway segments. While setting priorities for highway system funding was not a primary study objective, designated PA highways have greater potential for National Highway System (NHS) preservation funding and for other federal and state funding programs. Additionally, Study results may provide guidance for highway system project priorities and cost participation. 2 Study Scope and Process 2.1 Principal Arterial Characteristics The Study’s process began by identifying the major Dakota County highways to be evaluated, as noted above. All of these highways provide continuity over long distances, serving many trips, commuters, and population or employment destinations. The methodology for the Study then considered dozens of parameters based on FHWA, MnDOT, Metropolitan Council, and Dakota County guidance. Possible Consequences of Not Planning Ahead If more principal arterials are not considered, the County’s highway system might fail to support future needs. The possible outcomes include: An incomplete highway network Increasing traffic on highways not designed for needs Poor mobility; inefficient transportation system Likely increase in safety problems Unclear priorities for highway improvement projects and funding FINAL REPORT Page 4 June 2018 2.1.1 Review of Applicable Guidance – PA Characteristics Table 1 provides a complete list of characteristics to consider when looking at possible PA designations (non-freeway), based on the cited FHWA, Metropolitan Council, and Dakota County guidance. For each measure, the corridor and segments generally either meet the characteristic or not. In researching the guidance, the Study found PA characteristics could be described in two groups: Decision characteristics are those that most directly affect the suitability of corridors or segments to be future PA highways. These characteristics help establish if the highway is located well within the system and serves travelers in a manner consistent with a PA. Timing characteristics are those affecting the ease in which the corridor or corridor segments can be planned for, and adapted, to serve a PA function over time. These characteristics establish the “readiness” of the highway and could provide a basis for additional corridor planning. Both decision and timing characteristics were considered important decision-making factors; however, some characteristics proved more important to differentiate between highway characteristics than others. Therefore, Table 1 notes which characteristics are considered “Key Factors” for this Study’s corridor- and segment-level analyses. 2.1.2 Key PA Characteristics Used for the Study As noted under “Comments” in Table 1, the Study approach considered applicable guidance and the reasons why some characteristics were identified as key factors for corridor-level comparisons and why others were not. For example, some characteristics are based on high-level guidance only or will provide similar results for all corridors and, therefore, were not key factors for analysis of segments. As listed in Table 2 below, the Study’s framework for analysis and comparison of highway segments focused on a selected range of decision and timing characteristics. This focus helped to make the analysis more clear. 2.1.3 Additional Characteristics Observed for Dakota County Highways With the guidance in Tables 1 and 2 as a reference, this Study also found that Dakota County highways sometimes have characteristics or context which suggest additional inputs and details toward findings and recommendations. For example, these factors were observed: Land Use and the Presence of Transit – Dakota County has a number of public transit corridors with regularly scheduled service. The presence of scheduled transit service on was considered as noted in Tables 1 and 2. However, a lack of scheduled transit service in the rural parts of the County is expected and is thus not considered a relevant characteristic on rural highway segments. Freight Connections – While many highways are used by trucks, the Metropolitan Council’s 2017 Regional Truck Highway Corridor Study provided an objective means to check designations for existing routes. Figure 5 shows that most of study corridors are included as priority truck routes within the Metropolitan Council’s 3-tier scoring structure. ?§A@GÉWX ?tA@ ?§A@ GwWX )s ?ÕA@GÐWX GàWX ?ÕA@ G}WX !"b$ ?èA@)p G±WX !"`$ %&c( ?éA@ %&d( %&f( )s )p ?±A@ %&d( %&f( ?ÞA@ ?ØA@ )m ?ØA@ ?¸A@ ?ØA@ )m )s Source: Metropolitan Council, Regional Truck H ighway C orridor Study, 2017 The Freight Tier is a weighted score for prioritzing regional truck highw ay cor ridors.

TABLE 2. FRAMEWORK FOR ANALYSIS OF HIGHWAY SEGMENTS Highway Right-of-Way and Spatial Constraints – There are several Dakota County highway segments that do not have public rights-of-way established, but instead are reserved by highway easements. A highway easement is not a major concern by itself. However, some segments include combinations of incomplete right-of-way, narrow easements, or constraints from railroads, numerous nearby buildings/structures and many access points. Combinations of such factors are known to present capacity and safety challenges, perhaps limiting the readiness of a highway segment for designation as a PA. Highway segments that offered established rights-of-way and few spatial constraints were considered stronger from a timing or “readiness” perspective. Possible New Routings or Connections – Some of the corridors/segments included in the Study (CH 63, CH 70, MN 50, CH 86, and CH 23) include proposed, as-yet incomplete, connections or possible new connections. Such segments may be less ready for PA designation and might also affect the readiness of adjacent segments. The Study team also added the one-mile segment of CH 28 (Yankee Doodle Rd.) as a connector between CH 63 and MN 149. The combined segments form a north- south corridor with CH 28 as a lateral connection. 2.2 Input from Regional and Local Partners In completing the Study, Dakota County invited and encouraged participation from a full range of relevant partners, specifically: MnDOT Metropolitan Council Dakota County Scott County Cities of Apple Valley, Eagan, Farmington, Inver Grove Heights, Lakeville, and Rosemount Representatives of the County’s 13 townships and rural centers (under 5,000 residents each) Representatives of these agencies participated in periodic Study Management Team (SMT) meetings. The same agencies, as well as other invited stakeholders, were also involved in a series of four subarea outreach meetings, held from late November 2017 into January 2018.

The segments are grouped into four subareas (North, West, East, and South) to provide perspective on land use and travel characteristics. More details about the data considered for each segment, along with maps focused on features in each segment, are provided in Appendix A – Highway Segment Data and Detailed Maps. 3 Study Analysis and Results by Subarea This section provides summaries of the Study’s results by subarea (North, West, East, and South). Each summary statement highlights the important observations, including input received at referenced subarea meetings, along with the conclusions and recommendations. Figure 7 provides an overall introduction and summary to the conclusions and recommendations. 3.1 North Subarea 3.1.1 Observations and Input Received The North Subarea is a developed urban part of Dakota County and exhibits some of the highest traffic volumes observed on PA Study highways. The system issues for this subarea focused primarily on roles of north-south highways, including a future extension and connection on new alignment for CH 63 from I-494 to MN 55. The North Subarea Focus Group meeting was held on January 4, 2018. Comments, discussion, and analysis noted: Concerns about the characteristics of MN 3 (Study Segment 3A) which is mostly residential and includes curves which limit sight distance. Segment 3A is also not a designated truck route. The spacing between Study Segments 63 and 3A is roughly a half mile – too close for spacing guidance between two PA highways. Segment 3B, while constrained through Rosemount’s downtown, is an important north-south travel corridor in central Dakota County, connecting to St. Paul/Minneapolis to the north and to Farmington and Northfield to the south. The MN 149 Segment has importance as both a through route and as a route providing service to major employment and freight businesses (even while lacking designation as a freight corridor by the Metropolitan Council). The one-mile segment of CH 28 connecting CH 63 and MN 149 is included as a possible future PA because of its potential role in a future north-south PA system corridor.

Other segments (CH 63, CH 28, MN 149, and MN 3 from MN 149 to CH 42) are recommended as future PA highways, but not for near-term designation. 3.1.2 Conclusions and Recommendations for the North Subarea The segments in this subarea fit the characteristics of PA highways. However, the spacing is too close between future CH 63 and Segment 3A to recommend both as future PA segments. The CH 63 segment is forecast to serve more traffic, currently has dedicated right-of-way, and will provide design characteristics appropriate for a PA. Therefore, Segment 3A is not recommended as a future PA; all other segments in the North Subarea are recommended as future PA highway routes, but not for near-term designation. Segment 3B exhibits the above-noted constraints in Rosemount’s downtown. CH 28 is a possible connection along a future north-south PA corridor; its role in a future PA system will be confirmed through future designations. 3.2 West Subarea 3.2.1 Observations and Input Received Similar to the North, the West Subarea is generally a developed urban part of Dakota County and exhibits some of the highest traffic volumes observed on PA Study highways. In fact, CH 23 carries more traffic in the West Subarea than any other segments in the Study. The system issues for the West include the roles of CH 23 (north-south) and CH 70 (east-west). The mobility roles and connections provided by these two highways, which intersect in Lakeville’s Airlake Industrial Park area, are important factors in the overall PA Study because of the regional connections they provide. CH 70 is also planned to provide a future connection to Farmington, and via CH 74 (Ash Street) to MN 50 and US 61 (see more below in the East Subarea section). The West Subarea Focus Group meeting was held on January 8, 2018. Comments, discussion, and analysis noted: The meeting included representatives of Dakota County and local governments (Apple Valley and Lakeville) as well as developers. This led to discussions of land development issues, including the need to create a suitable system of local roadways along Study segments as development fills in. Dakota County and the communities closely involved in the West Subarea will need to engage on supporting studies, including the extension of CH 70 east to Farmington. The CH 70 - MN 50 - US 61 corridor presents a number of highway jurisdictions and, with completion of the proposed future connection to Farmington and to US 52, the regional importance of this corridor should be considered. This corridor includes connections to Lakeville’s Airlake airport and industrial park, to US 52, US 61, and to Scott County to the west (where Scott County Highway 8 has also been identified as a future PA). Similarly, it is noted that CH 23 transitions to the north to MN 77, an existing PA. FINAL REPORT June 2018 Page 9 WEST SUBAREA CONCLUSIONS: CH 23 from CH 42 to CH 70 and CH 70 from I-35 to CH 23 are recommended for near- term PA designation (the only two with this recommendation in the Study). CH 70 west of I-35 is recommended as a future PA, but not for near-term designation. Discussions noted the need for continued studies to address the design of CH 70, including the extension east to Farmington (joining CH 74 or Ash Street). CH 31, or Pilot Knob Road, was discussed as a locally important north-south corridor. This roadway has volumes in some segments that are comparable to parallel volumes on CH 23; however, unlike CH 23 or MN 3, it does not provide continuity south of Farmington and is not proposed to do so. 3.2.2 Conclusions and Recommendations for the West Subarea The segments in this subarea fit the characteristics of PA highways. Additionally, CH 23 and CH 70 in the West Subarea both exhibit reasonable available rights-of-way, good access spacing/management, and high posted speeds. In fact, Segment 23A is a 4-lane divided roadway for its entirety. The lands surrounding the two highways are established high-growth areas, with current growth and development evident as well as major commercial and freight uses (Airlake Industrial Park). Therefore, there is short- term risk of development patterns that conflict with PA highway characteristics. Considering these observations, Study objectives, and connectivity to existing PA segments to the north (MN 77 and CH 42) and west (I-35), Segments 23A and 70B are recommended for near-term PA designation. These are the only two segments in the PA Study recommended for near-term designation. The only other segment in the West Subarea, Segment 70A west of I-35 is recommended as a future PA highway route, but not for near-term designation. 3.2.3 West Subarea Functional Class Change Recommendation and Process The process for accomplishing a functional classification change warrants attention for the above- referenced segments of CH 23 and CH 70 (23A and 70B). As noted, these are the only two links recommended in the Study for near-term designation as PA highways, and they were identified based on characteristics that strongly reflect existing and future roles in the system. These two segments also fit together in a future PA system because they intersect to complete a new stage for the overall system. Specifically, PA highways should interconnect; and this recommendation would add both north-south and east-west links to the system, connecting at a common point. While the timeframe to formally complete the recommended designation of these segments as PA highways is not certain, the process is laid out by MnDOT and the Metropolitan Council. See applicable guidance at: www.dot.state.mn.us/roadway/data/functional_class.html As noted in the detailed guidance for a functional class change process, MnDOT has the primary responsibility for developing and updating the statewide highway functional classifications (23 CFR §470.105). However, the change process will begin by Dakota County completing and submitting a FINAL REPORT Page 10 June 2018 EAST SUBAREA CONCLUSIONS: All segments are recommended as future PA highways, but not for near-term designation. These include MN 3 from CH 42 south to MN 50, the future connection of CH 70 from CH 23 to MN 3, and MN 50/US 61. “Functional Classification Change Request” form to the Metropolitan Council. The referenced federal regulation requires MnDOT’s cooperation with local officials in developing and updating the functional classification and the Transportation Advisory Board (TAB) typically reviews change requests. 3.3 East Subarea 3.3.1 Observations and Input Received The East Subarea has important connections to the North and West Subareas via MN 3 to the north and the future connection to CH 70 to the west. Transitional land use is an important characteristic of the area, with both urban and rural areas observed. Traffic volumes reflect this transition, as they vary widely in segments. The system issues for the East include the connections to the fully urbanized parts of Dakota County (north and west as noted above) and the regional connections to communities in bordering counties such as Northfield (south) and Red Wing (east). As discussed for the West Subarea above, CH 70 is planned along a future connection linking Farmington to Lakeville and to I-35 more directly than provided by existing CH 50. Therefore, the regional importance of the CH 70 - CH 50 - MN 50 - US 61 corridor is also a consideration to the east. The East Subarea Focus Group meeting was held on November 30, 2017. Comments, discussion, and analysis noted: Similar to the discussion noted above for the West Subarea, participants asked about CH 31 (Pilot Knob Road). While this roadway exhibits some relatively high volumes, it does not provide continuity south of Farmington and is not proposed to do so. The need for continued studies involving Lakeville and Farmington, in part to address the proposed design for the CH 70 extension, connecting to MN 50 in Farmington via CH 74 (Ash Street). The need to manage highway access and mobility through the small but growing communities to the east – Hampton, New Trier, and Miesville. The Focus Group discussed traffic counts and noted the 2030 forecast volumes for MN 50 east of Hampton (Segment 50B/61) suggested a reduction in travel demand versus counts in 2014 and 2015. MnDOT’s counts are updated every three years and Dakota County typically updates counts semi-annually; forecasts are now also getting updated. The low growth forecast for MN 50 out to 2030 was partially based on limitations of the regional travel model at the edges of the metro area, as well as need for updates. For purposes of this study, the 2030 forecast volumes to the east will suggest a flat forecast as a placeholder rather than a future reduction (Appendix A). 3.3.2 Conclusions and Recommendations for the East Subarea The segments in this subarea fit the characteristics of PA highways and all are recommended as future PA highway routes, but not for near-term designation. The segments include MN 3 from CH 42 south to MN 50, the future connection of CH 70 from CH 23 to MN 3, and MN 50/US 61 extending east to the FINAL REPORT June 2018 Page 11 SOUTH SUBAREA CONCLUSIONS: CH 23 from CH 86 to MN 19 in Northfield is not recommended as a future PA route. All other segments (CH 23 north of CH 86, MN 3, and CH 86) are recommended as future PA highways, but not for near-term designation. county line. As noted for both the West and East Subareas, the regional importance of this multi- jurisdictional corridor should be considered in future studies. 3.4 South Subarea 3.4.1 Observations and Input Received The South Subarea is rural, but includes future growth areas. With limited local traffic generators, the highways in the South are often used for through trips and provide important connections to jobs and commerce. The system issues for this subarea include connectivity to the West and East Subareas (noted above), to I-35, to existing PA segments in Northfield, and to Rochester via US 52, an existing PA. The South Subarea Focus Group meeting was held on December 13, 2017. Comments, discussion, and analysis noted: The southern-most segments of CH 23 (Segments 23C and 23D) are spaced closely with the parallel segment of MN 3, Segment 3E (the highways are 3 miles apart or less). This compares to guidance for rural-area spacing of 6-12 miles. The Metropolitan Council includes MN 3 within its freight tiers, including Segment 3E (see Figure 5, above). The parallel Segments 23C and 23D are not identified as designated truck routes. Participants discussed observations of lower forecast volumes on the above-noted segments of CH 23 vs. the parallel segment of MN 3 and also noted: o MN 3 currently serves as the more direct and primary north-south route through Northfield. o There are potential challenges with the future connection proposed for CH 23 into Northfield (Study Segment 23D). Land uses in the area proposed for the future connection include a solar farm and land owners may not be supportive. CH 86 is a locally important east-west corridor, connecting to US 52 to the east and to Scott County destinations and I-35 to the west (it is noted as a future Scott County PA). However, CH 86 has right- of-way constraints in Castle Rock and lacks a direct connection to I-35. An interchange with I-35 has been proposed for the CH 86 overpass location; but this is a long-term concept and no serious studies have been undertaken. 3.4.2 Conclusions and Recommendations for the South Subarea The segments in this subarea typically fit the characteristics of PA highways. However, the spacing is close between the southern-most portions of CH 23 and MN 3, and relative importance in connecting to Northfield is an issue as noted above. The MN 3 corridor provides a more direct alignment using all existing roadway and will carry greater forecast volumes. Given the comparisons noted, and the FINAL REPORT Page 12 June 2018 are recommended as future PA highway routes, but not for near-term designation. 4 Study Conclusions and Next Steps This Study concludes with the above-noted subarea recommendations, including the proposed near- term official designation of CH 70 east of I-35 and CH 23 north of CH 70 as PA highways (West Subarea). Figure 8 summarizes next steps, which will include noting recommendations in the County’s 2040 Transportation Plan. Other elements of future highway system management are outlined below. 4.1 Near-Term PA Segment Designations The proposed near-term designations will be formally addressed in the coming months or years with the Metropolitan Council and MnDOT. This Study’s results will also be updated over roughly the next 10-12 years and will be reflected in transportation plans and through proactive management of the County’s system. As detailed in Section 3.2.3 above, two segments of CH 23 and CH 70 (23A and 70B) are recommended in the Study for near-term designation as PA highways. Applicable guidance for changes to functional class is available at this MnDOT web page: www.dot.state.mn.us/roadway/data/functional_class.html Actions to resolve the proposed new designations will include Dakota County completing and submitting a “Functional Classification Change Request” form to the Metropolitan Council and review by the Transportation Advisory Board (TAB). See Section 3.2.3 for more information. 4.2 Management of Future PA Highways; Benefits Most of the highway segments evaluated in this Study have characteristics suggesting potential to become PA highways in the future. However, timing characteristics are often not strong enough to justify near-term designations. For example, in the North Subarea, there are complexities with multiple routes and the need to complete design and construction of CH 63. Other planning to add future connections (for example, the CH 70 extension) and to address constrained rights-of-way will be needed to address the readiness and sequence for additional designations. See Appendix A for more details on such planning needs, by segment. 4.2.1 Arterial Access Management, Local Planning, and PA Cost Participation As growth and development occurs along the corridors, cities and townships can be proactive to: FIGURE 8. SUMMARY OF NEXT STEPS FINAL REPORT June 2018 Page 13 Cooperative planning and design for existing and future PA highways should follow access-spacing guidance and consider parallel local roadways to support the arterial. Reflect highway system plans in local plans Support and facilitate access management and right-of-way goals for future PA highways Attention to access management is important to provide safe and efficient arterials and develop well- planned roadways and communities, regardless of cost participation policies. But additionally, Dakota County’s cost participation policy for cities with 5,000 persons or more is based on access spacing goals and PA designation. As illustrated in Figure 9, the County’s current policy limits local cost participation to 25 percent when an arterial is managed to limit full access to ½-mile spacing or if the arterial is a designated PA highway. As this study concluded, Dakota County was considering possible revisions to this policy (as part of the 2040 Transportation Plan) which could further reduce a city’s cost participation if the arterial is a currently designated PA highway or a future PA based on this Study. In townships and cities with less than 5,000 in population, funding for Dakota County and Trunk Highway projects is provided primarily through federal, state, and county sources. 4.2.2 Arterial Access Management in Growing Communities Figure 10 provides four general illustrations of how growth may occur in relation to access management measures on a multi-lane arterial. In Dakota County growth areas, roadway design and access management on future PA highways should consider the potential to maintain ½-mile full-access spacing to provide safety and mobility benefits as well as conformance with County guidance. Cooperative planning among local jurisdictions, Dakota County, and MnDOT is the recommended best practice. As shown, development-driven adjustments to access on existing and future PA highways should be planned based on the ½-mile full-access spacing guidance. Additionally, parallel local roadways designed to support the arterial should be considered as part of the planning process (Figure 10, illustration no. 4). FIGURE 9. CURRENT COST PARTICIPATION POLICY AND LOCAL SHARE FINAL REPORT Page 14 June 2018 4.2.3 Study Benefits for Regional and Local Planning This Study provides a long-range perspective for Dakota County’s arterial highway system, with two segments on CH 23 and CH 70 proposed for near-term designation as PA highways (Section 3.2.3). Because of this, the benefits of the Study are to: FIGURE 10. EXAMPLE OF ARTERIAL ACCESS MANAGEMENT PROGRESSION FINAL REPORT June 2018 Page 15 Clarify Dakota County’s perspectives on which arterial highways have importance both regionally and locally. Inform regional transportation planning intent, as Dakota County’s conclusions can be reflected in the Metropolitan Council’s Transportation Policy Plan (TPP) and in long-range MnDOT plans. Provide information about each of the arterials addressed herein as background for future highway corridor and design studies. As noted in Section 1, the Study does not complete a formal decision-making process for designation of new PA highway segments. Nor does the Study set priorities for highway system funding. However, it does provide supporting data and guidance for the next formal steps (selected PA designations); and it may serve as guidance for highway system project priorities and cost participation. 4.2.4 Review of Dakota County’s Next Steps With reference to the details above (including Section 3.2.3), Dakota County’s next steps include: Complete and submit a “Functional Classification Change Request” form and supporting information to the Metropolitan Council, requesting portions of CH 23 and CH 70 (segments 23A and 70B) be classified as PA highways. Working with local officials (including the Cities of Apple Valley and Lakeville), support the Met Council and MnDOT functional classification change review and determination process. Include the results of this Study in its 2040 Transportation Plan. Communicate with stakeholders about the benefits of corridor management on the future PA highways, including potential for reduced shares of local government cost participation for highway improvement projects. Use this Study to guide additional planning actions and priorities. For example: o Provide continued leadership, technical assistance, guidance, and input to corridor planning for future PA highways and to address other Dakota County highway system issues (refer to the analysis by segment in Table 3 and Appendix A). o Encourage cities and townships to plan for future PA highways, including planning for access management and right-of-way goals in constrained areas.
