18 MAPO Transportation Resolution Plan 1. Plan for the long term improvement of County Road 73 as presented in Scenario D-Refined (not along Akron) if and when improvements are needed Supports long-term vision of Akron as a city collector street Future County Road 73 belongs in a different location Consistent with Rosemount City Council Action Future approvals would be needed by each city and County Board to move forward with implementation and project(s) Roadway construction/reconstruction Flint Hills (MOU/acquisition) Basis for potential turnback agreement with Rosemount

19 MAPO Transportation Resolution Plan 1. Plan for the long term improvement of County Road 73 as presented in Scenario D-Refined (not along Akron) if and when improvements are needed Provides for a continuous roadway system in the study area Exact alignment and project scope will be determined when needed Avoids investing in a County road twice for County 73

20 MAPO Transportation Resolution Plan 2. Plan for the long term improvement of County State Aid Highway 32 as presented in Scenario D-Refined if and when improvements are needed If and when needed, improve County 32 to a 4-lane roadway from Trunk Highway 3 to Trunk Highway 52, and realign from Akron to 117 th Street Timing of realignment likely tied to realignment of County 73 due to Bituminous Roadway mining, and design considerations Supports functionality of 117 th Street as a future County roadway and County participation in improvements

21 MAPO Transportation Resolution Plan 2. Plan for the long term improvement of County State Aid Highway 32 as presented in Scenario D-Refined if and when improvements are needed Provides for a continuous roadway system in the study area Exact alignment and project scope will be determined when needed

22 MAPO Transportation Resolution Plan Improvements to 117 th Street (future County 32) Work with IGH to improve 117 th Street to a 4-lane facility with turn lanes and access management for safety. Include improvements at County 71. Include in eligible list for Sales and Use Tax CIP and add as a project in the Sales and Use Tax CIP

23 MAPO Transportation Resolution Plan 3. Assess the long term alignment for County State Aid Highway 71 south of 117 th Street at the time County Road 73 is fully realigned, as presented in Scenario D-Refined. Dependent upon traffic conditions and projections at the time of design Exact alignment and project scope will be determined when needed

24 Resolution And; BE IT FURTHER RESOLVED, That the Dakota County Board of Commissioners directs staff to consider future improvements in the study area, consistent with implementation of Scenario D-Refined, as mutually agreed upon between the County and the city the improvements are located in, through the County s Transportation Capital Improvement Program process.

25 PROPOSED AMENDMENT: And; Resolution BE IT FURTHER RESOLVED, That the actual location of future roadway and intersection alignments and design of improvements, consistent with Scenario D-Refined, will be based on conditions existing at the time of the improvement, as mutually agreed upon by the County and the city the improvements are located in, taking into consideration input from City Councils, residents and businesses.

26 MAPO Transportation Resolution Plan What s Been Done in the Recommended CIP Removed improvements to existing Akron in IGH Included improvements to existing Akron in Rosemount (2020 Construction) Added CSAH 32 to Recommended Eligible Project List for Transportation Sales and Use Tax (including 117 th Street) Added 117 th Street to the Recommended Transportation Sales and Use Tax CIP

27 MAPO Transportation Next Plan Steps Next Steps Recommended Transportation CIP Pending Adoption Recommended Transportation Sales & Use Tax CIP Pending Adoption Begin design for Akron in Rosemount in 2018 Work with Inver Grove Heights on a project for 117 th Street contingent on their schedule Begin discussions with Flint Hills on a Memorandum of Understanding for future R/W Acquisition

35 MAPO LONG Transportation RANGE COUNTY HIGHWAY Plan SYSTEM PLAN Current map defines long-term improvement needs based on 2030 traffic projections in Transportation Plan Used as part of the plat review process to minimize future right of way issues created by new development 2 Lane Divided/3 Lane Undiv. 4 Lane Divided 6 Lane Divided

36 County 73 Improvements MAPO Transportation Plan Rosemount CIP request for County 73 improvements The City of Rosemount would still pay 45% for the ½ mile segment that is not future turnback, per County policy. Build future turnback segment of CR 73 to city collector standards at 100% County cost, per County policy. No changes to Akron in IGH at this time 1 mile Rosemount improvements include ½ mile of long term CR 73 and 1 mile of future city street Long Term Alignment for CR 73 ½ mile

37 MAPO Frequently Transportation Asked Plan Questions UMORE is currently being mined, and will be for decades. Won t that preclude future development and roads? As mining is completed, development will occur. This is typical, and is currently happening in Apple Valley along County 46 and County 31. County/cities have successfully worked with mining companies and developers on roadways. U of M is exploring purchase agreements for 595 acres

38 MAPO Frequently Transportation Asked Plan Questions Will traffic control at major intersections along County 73 need to change? Questions have been raised at County 42, Bonaire Path, and County 32. These intersections will be monitored for the need for traffic control changes consistent with intersections across the County system. The need for changes is not anticipated in the short term.

39 Frequently Asked Questions MAPO Transportation Plan Won t existing Akron become a shortcut when County 73 is realigned in the future? Resolution says that roadway and intersection alignments will be determined and agreed upon by the County and City taking into consideration input from residents and businesses Cities and Dakota County will work together at the time of full realignment of 32 and CR 73 on connection details. Connection to County 32 will be determined in the future by City and County with input from residents and businesses City street when County 73 is realigned CSAH

40 MAPO Frequently Transportation Asked Plan Questions Isn t the access spacing between 118 th and Albavar a problem? Spacing is about 300 (less than guideline of ¼ mile) The offset allows for left turn lanes for both intersections. This spacing is more of an issue if turn lanes are not built Long-term plan is for Akron to become a City collector. This is also a larger issue if that is not the plan.

41 MAPO Frequently Transportation Asked Plan Questions What are the implications of the Koch Jet Fuel Pipeline? This will need to be addressed through the design process for any future improvements on County 73. It would be most prudent to avoid the portion of the pipeline currently outside of the County 73 right of way.

42 MAPO Frequently Transportation Asked Plan Questions Is Akron Avenue the right location for County 73 in the long term? Discontinuous system and implications for safety and efficiency Changing land uses along the southern portion of the corridor coupled with existing rural residential land uses that will not change Investments should fit with a long-term plan

43 Study Process MAPO Transportation Plan Scenarios B and D were refined to improve safety and to reduce costs/impacts Phasing of improvements was also assessed considering short-term and longterm needs High-level planning cost estimates for comparison (phasing element) Scenario B Refined and Scenario D Refined similar in cost with jet fuel pipeline cost risks taken into account Other alignments for Scenario D were also reviewed Resident proposal

44 Study Process MAPO Transportation Plan Additional Alignments Reviewed Greater circuity reduces functionality 50% greater than the cost of Akron in interim Skewed intersections at 117 th Street and County 32 Requires realignment of County 71
