2 WHY ARE WE CONDUCTING THE ARTERIAL CONNECTOR STUDY? Dakota County and the cities of Rosemount, Inver Grove Heights, and Eagan are working together toward a common goal of proactively planning for future transportation needs based on the expected growth and development identified in their Comprehensive Plans. The Dakota County 2030 Transportation Plan identifies the need for this study: Increase in traffic with proposed planned growth Disconnected north/south and east/west county roadway system through area Bridge gap between area of adjacent studies The Dakota County Arterial Connector Study will help prioritize future infrastructure improvements and reduce long-term costs and future right-of-way impacts. What is the purpose of the Open House? The purpose of the open house is to provide an update on the study process. The open house provides an opportunity to display the refined alternatives undergoing further evaluation and solicit feedback to assist in the selection of a preferred alternative. What have we heard from affected stakeholders? Provide further definition of project need Explain how area growth was developed Denote fuel pipeline along Akron Avenue Provide relative scenario costs Consider impacts to residents and businesses Take more time to listen to resident concerns and work through the issues Address short-term needs in consideration of long-term vision options How have we responded? Shared additional assessment with the following stakeholders Bituminous Roadways Flint Hills Residents along/near Akron Avenue Businesses along 117th Street

5 STUDY GOALS GOAL 1 Encourage planning and design of an arterial roadway system that accounts for future travel growth and planned development. GOAL 2 Enhance transportation system efficiency and mobility. GOAL 3 Improve transportation system connectivity, spacing, and continuity. GOAL 4 Enhance the safety of the traveling public. GOAL 5 Encourage preservation of right-of-way for future transportation corridors. GOAL 6 Coordinate with potential greenway alignments, other bicycle/pedestrian facilities, transit connections, and rail alignments. GOAL 7 Consider adopted plans/studies and maintain interagency coordination in developing the future transportation system. GOAL 8 Minimize social, environmental, and property impacts as much as possible while achieving the desired functionality out of the transportation system. GOAL 9 Maximize cost effectiveness of the overall transportation system vision, as well as its flexibility to be implemented over time.

6 LAND USE Existing Land Use (Inver Grove Heights) Future Land Use (Inver Grove Heights) Existing Land Use (Rosemount) Future Land Use (Rosemount) UMore Concept Master Plan The Concept Master Plan for the University of Minnesota s New Sustainable Community at UMore was completed in The result of an intensive two-year planning process, the concept master plan identified a future development pattern from the UMore property. The study is a foundation element for the AUAR completed in The land use plan contained in the study is the basis for three of the four scenarios being considered: Biscayne Avenue CR Approximately 4,900 acres CR 46 Scenario 1 future population of 35,000 people and about 18,000 jobs Scenario 2 future population of 25,000 people and about 18,000 jobs 170 th Street Scenario 3 future population of 31,500 people and about 24,500 jobs Scenario 4 consistent with current Comprehensive Plans of both the City of Rosemount and Empire Township Vermillion Highlands A Research, Recreation and Wildlife Management Area 2,822 Acres

11 SCENARIO ASSESSMENT qq Scenarios A and C failed to meet the safety and mobility criteria that were established: ELIMINATED ELIMINATED Scenario A: Required an intersection within a high speed curve Did not meet design speed through horizontal curves Scenario C: Did not meet design speed through horizontal curves Included an intersection closely spaced to horizontal curve qq qq To continue the planning process, Scenarios B and D were evaluated in more detail and refinements were made to these two scenarios to address project needs and stakeholder feedback. Scenarios E and F carried forward - intersection configuration to be determined with project implementation/ further review.
