Riverstone South EAW January 2021 c. Identify measures that will be taken to minimize or mitigate project related transportation effects. The Traffic Impact Study recommends construction of the Highway 10/Riverdale Drive intersection to a 3/4-access (Appendix G). This configuration removes the cross -street left turning movement (northbound left) from the intersection and improves the traffic operations to acceptable timing. This reduction in queueing and delay is a result of rerouting the highest delayed movement (northbound left turning movement) away from the Highway 10/Riverdale Drive intersection to alternative routes. Vehicles that would normally navigate northbound to westbound at this intersection would instead travel east on Riverdale Drive to the Armstrong Boulevard/Northern Highway 10 Ramps, where they would take a northbound left to proceed westbound. The Technical Memorandum included in Appendix G indicates traffic turning left from northbound Armstrong Boulevard to westbound Highway 10 will operate within acceptable ranges of delay for all scenarios analyzed. In total, roughly 2.25 miles would be added to their commute with this change. Very few trips are affected by the northbound left turning movement at this location. Existing traffic counts estimate that fewer than 60 vehicles complete this movement each day. Additionally, pedestrian and bicycle infrastructure upgrades are recommended with trail connections to existing facilities along Riverdale Drive east of Llama Street and the existing trail south of Highway 10 by Bowers Drive. 19. Cumulative Potential Effects Preparers can leave this item blank if cumulative potential effects are addressed under the applicable EAW Items. a. Describe the geographic scales and timeframes of the project related environmental effects that could combine with other environmental effects resulting in cumulative potential effects. It is anticipated that the project area will develop over the next 3 to 5 years, but the actual timing of development could vary depending on the demand for housing and market conditions. Seven other projects proposed in the City of Ramsey are expected to develop during this time period. These projects and their geographic locations are described under Item 19.b below. b. Describe any reasonably foreseeable future projects (for which a basis of expectation has been laid) that may interact with environmental effects of the proposed project within the geographic scales and timeframes identified above. The City of Ramsey is reviewing and has recently approved other development projects that are located 0.2 to 3.8 miles from the Riverstone South development site (Table 10). These projects are all residential developments. Projects in close proximity to Riverstone South could potentially interact to result in cumulative effects. 32
