CC Regular Session 5. 14. Meeting Date: 04/12/2022 By: Bruce Westby,Engineering/Public Works Information Title Adopt Resolution#22-088 Amending Improvement Project#20-05, Riverdale Drive Extension,to Reconstruct Riverdale Drive from Llama Street to Armstrong Boulevard Interchange Purpose/Background: Purpose: The purpose of this case is to adopt Resolution#22-088 amending Improvement Project#20-05, Riverdale Drive Extension, Llama Street to Bowers Drive,to include the reconstruction of Riverdale Drive between Llama Street and the segment of Riverdale Drive constructed as part of the Armstrong Boulevard&Highway 10 interchange in 2014-2015. Background: In 2015, construction of the Armstrong Boulevard&Highway 10 interchange was completed,which included reconstructing Riverdale Drive to a point approximately 1,200 feet east of Llama Street,just east of the mid-block crosswalk. See attached Figures 1, 2 and 3 for reference. The original segment of Riverdale Drive between Llama Street and the segment of Riverdale Drive constructed as part of the Armstrong Boulevard&Highway 10 interchange was proposed to receive mill and overlay improvements in 2022 per the 2022—2031 Capital Improvement Plan(CIP). Attached is the CIP sheet outlining this project. Also attached is a street segment summary that shows this segment of Riverdale Drive,which is approximately 1,280 feet long,was originally constructed in 1997,was sealcoated in 2002 and 2012, and had a 2020 PASER rating of 6. This street segment is 25 years old and is in such condition that a mill and overlay improvement project would likely last about 15 years before the street would need to be reconstructed. Staff therefore recommends reconstructing this segment of Riverdale Drive as part of Improvement Project#20-05 to avoid leaving an older segment of pavement with a substandard drainage system between two new segments, which will likely result in the need to reconstruct this segment in less than 20 years. At that time the work would need to be completed under traffic as there will be no alternate access for residents living on Bowers Drive, in the Riverstone South development, or for the commercial and industrial properties along Riverdale Drive west of Armstrong Boulevard. Staff projects the traffic volumes on this segment of Riverdale Drive will be somewhere between 4,000 and 6,000 vehicle trips per day within 15 years. Notification: Notifications are not required for this case. Observations/Alternatives: Observations: MnDOT has confirmed that this work can be added to Improvement Project#20-05 without impacting the awarded LPP funding,but that LPP funding will not be increased because of this additional work. Alternatives: Alternative#1:
