3 Conceptual Plan Process Stakeholder Meeting Stakeholder Meeting Stakeholder Meeting OPEN HOUSE Primary Project Considerations: Multi-modal Operations Safety Aesthetics Environmental/ Sustainability Property Impacts & Cost Concept Development Feedback on Four Preliminary Design Elements On-street Bike Lanes On-street Parking Left Turn Lanes Medians Concept Refinement Feedback on Concept Plans & Streetscaping Recommended Concept Plan City of Eden Prairie West 70 th Street

4 On-Street Bike Lanes Separates pedestrians and bikes in heavy usage area near LRT station Utilizes the additional pavement width needed for large vehicles Provides enhanced commuter bike facilities Recommend providing on-street bike lanes City of Eden Prairie West 70 th Street

5 On-Street Parking Existing land uses do not need or utilize on-street parking Design will consider the potential for future on-street parking with redevelopment Increases the overall footprint (size) of the roadway Not recommending providing on-street parking City of Eden Prairie West 70 th Street

6 Left Turn Lanes A two-lane roadway provides acceptable operations Forecasted traffic volumes are not high enough to warrant left turn lanes (5,000-7,000 vehicles per day) Left turns will be provided at Flying Cloud Drive and Shady Oak Road for improved intersection operations Increases the overall footprint (size) of the roadway Not recommending left turn lanes along the corridor City of Eden Prairie West 70 th Street

7 Provides gateway and aesthetic enhancement Allows pedestrian refuge Can be designed to accommodate turning movements for large vehicles Increases overall footprint (size) of the roadways To minimize the overall footprint, could be placed at key locations Considering medians at each end and at the LRT station, not along the entire corridor Median City of Eden Prairie West 70 th Street
