9. Speed limit on MN 97 Staff Report Date of Meeting: September 5, 2018 To: City Council From: Neil Soltis, Administrator Re: Speed limit on MN 97 Background: Based on public comments Mayor Maefsky has requested a discussion of speeds on MN 97 past the Village Center. The concerns voiced include: asking for another speed study, asking about making the crosswalk at Oakhill more functional, installing electronic speed tracking devices coming from both (or one?) directions, and installing slow down signs. City Engineer Ryan Goodman has highly recommended that the City do their own investigation first to gauge what speed is actually occurring on this stretch of roadway (speed trailer or County Deputy with radar) before requesting the MnDOT perform a speed study since such a study is based on the average speed and can result in an increase to the speed limit. The Cities of Marine and Stillwater have installed electronic speed signs recently along MN 95. Ryan has provided the information on the signs that were installed in Marine. All work was 100% local cost, and had to be approved through MnDOT prior to installation. Marine’s construction cost was approximately $35K and included speed limit indicator signs (x2), advance flasher signs, and 1.5” conduit for power service to the speed limit indicator signs as solar power in this area doesn’t work well because of the trees/valley. New project costs that could be expected: • Speed Indicator Sign – $4,000-$5,000 • Source of Power (Only need solar or hard wire, not both) o Solar Package - $2,000 o Hard wired - $7,000 see below • Service Cabinet - $4,000 • Cabinet foundation - $1,300 • Handhole (x1) - $700 • Conduit & wiring (estimate) - $1,000 Prices for the sign and solar package are materials only. Ryan found a recent bid for a hard wired speed indicator sign in Prior Lake, the bid price was $12,000
