Executive Summary Background: Riverstone Development, LLC and Capstone Homes, Inc are proposing the Riverstone South Residential development located South of Highway 10, between Bowers Drive and Llama Street in Ramsey, MN. The purpose of this study is to determine the traffic impacts associated with the build -out of the proposed development on the study roads and intersections where potential impact is anticipated. Mitigation measures will be analyzed and recommended if traffic operations are expected to be below traffic engineering standards. It should be noted that minor impacts are expected on corridors not analyzed in this study and improvements along those corridors may be needed in the future to accommodate incremental traffic growth from this and other area developments. Results: The principal findings of this study are: • The proposed development is expected to generate 1,912 new trips during an average weekday, 140 new trips during the a.m. peak hour, and 186 new trips during the p.m. peak hour. • All study corridors are projected to operate with volumes within their planning level capacity through the 2040 build scenario. • All study intersections except for Highway 10/Riverdale Drive (currently Highway 10/Bowers Drive) are projected to operate with queues and delays within acceptable bounds through the 2040 build scenario. • Highway 10/Riverdale Drive (currently Highway 10/Bowers Drive) experiences larger than preferred queueing with excessive delays in the 2022 and 2040 no -build scenarios. Restriction of this access to a 3/4-access, where the northbound left -turning movement from Riverdale Drive to Highway 10 westbound is no longer allowed, reduces the queues and delays to acceptable levels for all analyzed scenarios. • No external bicycle or pedestrian connections are shown in the provided site plan. Recommendations: The following items are recommended based on the analyses contained in this study: • The future Highway 10/Riverdale Drive intersection should be constructed to a 3/4- access, eliminating the northbound left turning movement. • A trail with a 10-foot minimum cross-section should be constructed on the south side of Riverdale Drive connecting to Highway 10/Riverdale Drive and the existing trail on the south side of Highway 10 to the current trail system on the south side of Riverdale Drive to the east of Llama Street. This study is based upon a concept development plan titled "Riverstone South" and dated October 21, 2020. Assuming the general characteristics of the proposed development remain approximately the same as documented, minor changes in the final design are not expected to alter the results or recommendations of this study.
