5. Conclusions and Recommendations The traffic impacts and operation of the proposed Pearson Farm Development were thoroughly studied and the principal findings are: • The proposed expansion is expected to generate approximately 2,912 new trips during an average weekday (1,456 entering and 1,456 exiting), approximately 227 new trips during the a.m. peak hour (53 entering and 174 exiting) and approximately 297 new trips during the p.m. peak hour (189 entering and 108 exiting). • The existing study intersections operate with acceptable delays and vehicle queues today. • The study intersections are expected to operate acceptably during the 2040 no-build and build scenarios. • Left turn lanes are not warranted based on the expected 2040 build year volumes and mainline speeds. • Right turn lane warrants are not fulfilled due to the mainline speeds remaining below 45 MPH, which is consistent for neighborhood streets, however, the right turn lane volume thresholds were reached by the estimated 2040 Build volumes. The following recommendations are made based on the above findings: • No additional intersection mitigation is required to help improve capacity. • If the speed limits along Puma Street or Alpine Drive are increased to 45 MPH or higher, re-evaluate the Turn-Lane warrants. • Construct a new sidewalk/trail along the southern edge of Alpine Drive connecting the proposed access to the existing Alpine Drive/Puma Street intersection. The addition of a north/south crosswalk should also be considered at this intersection to help promote safe crossing to the existing northern sidewalk/trail. • Ensure the proposed internal sidewalks connect to the external sidewalk/trail system. • Work with Metro Transit or their affiliates to improve transit options within the project area as the closest existing transit is located roughly 1 .5 miles away at Ramsey Station and Platform.
