Anoka County expects to receive final studies for each intersection in early 2022 to allow construction to occur in the summer/fall of 2022. Anoka County is not proposing to complete FYA improvements to any signal systems in the City of Ramsey in 2022. No FYA improvements are proposed at the intersections of Alpine Drive & Sunfish Lake Boulevard/CSAH 57, Alpine Drive & Nowthen Boulevard/CSAH 5, or Sunwood Drive & Ramsey Boulevard/CSAH 56, which have been discussed on several occasions. FYA Operations at Sunwood Drive & Ramsey Boulevard/CSAH 56 During the regular City Council meeting on September 22, 2020, the City Council received a request from Ramsey resident and Planning Commission Chair Randy Bauer to install FYA's at the intersection of Sunwood Drive & Ramsey Boulevard/CSAH 56. Mr. Bauer stated that he frequently waits at this signal system to turn left when no vehicles are approaching from the other direction. Pursuant to attached Ramsey City Council Resolution #21-302, adopted October 26, 2021, Staff hired SEH, Inc. to study the feasibility for installing FYA improvements at Sunwood Drive & Ramsey Boulevard/CSAH 56. Attached is a copy of the final SEH study. In summary, SEH's study notes the following findings; • The City should be able to consider using Flashing Yellow Arrow operations at this intersection during several hours of a typical day. However, due to higher posted speeds and higher peak hour traffic volumes on CSAH 56, along with higher peak left turning traffic volumes on Sunwood Drive, SEH has concerns about operating with flashing yellow arrow operations on each roadway during these peak traffic periods. • For the Sunwood Drive approaches, SEH recommends considering protected only left turn phasing be used both weekdays and weekends between the hours of 3:30 - 5:30 pm. For all other hours of the day and all hours on weekends, protected/ permissive flashing yellow arrow operations should be able to be utilized. • For the CSAH 56 approaches, SEH recommends considering protected only left turn phasing be used on both weekdays and weekends between the hours of 6:30 am - 8:30 am, and also between 3:30 - 5:30 pm. For all other hours of a typical weekday and weekend, flashing yellow arrow operations should be able to be utilized on CSAH 56. • To allow for flashing yellow arrow operation on each intersection approach, we estimate that these modifications (completed by an electrical signal contractor) will cost approximately $94,000. A detailed preliminary engineer's estimate of costs is attached to the study. Timeframe: Staff anticipates 15 minutes will be needed to present this case and respond to questions.
