Data: Data collected to date ranges from August 2020 to present. Data was collected on Long Lake Road, Red Oak, Spring Lake Road, H2, and Groveland. Data includes 12 one -week observations for Groveland from 2020 to present, 4 observations from Long Lake - all in 2022, 5 observations for Red Oak from 2021 to present, one observation in 2021 for SLP road, and two observations in 2023 for H2. More data was attempted but equipment and staffing issues impacted. Summary results H2 receives the greatest volume followed by Long Lake, then Red Oak, then Groveland with SLP road last. The highest average speed occurs on SLP road, with Long Lake second, Groveland Third, H2 and Red Oak last. Of particular interest is the speed and volume on Groveland for 2023 versus 2022 showing about a 10% drop from the 85' percentile moving from 35-37 to 32-33. This could be attributed to stop signs, but also could be due to higher volume, which tends to slow traffic. Volume stayed static as compared to previous years for one week but experienced almost a 15% increase for the other week. Due to SLP road being under construction, it is difficult to determine if traffic was pushed from one street to the next or if Groveland was used more due to the construction on SLP. Impact Studies: Staff spent a measure of time researching data delineating the difference of consequence to the human body if impacted by a car going X speed. Logically, the higher the speed, the greater the chance of bodily harm. Like all things googled, volumes of data — 60,400,000 hits. In short, there is a clear relationship between speed and injury/death. Lowering speed limits by 5 mph (from 30 to 25), theoretically would reduced the average speed from present to 5mph less. That difference would reduce the chance of serious injury somewhere between 10% to 25%; depending on which study. Next Step: Council needs to digest the data and information received to date, determine if more data collection is needed/warranted, make some determination regarding stop sign experiment, and discuss changing speed limit city wide. There is no immediate decision or action needed, rather an introduction of the issue. Don will have signage costs estimates at the meeting Item 7 — Citizen Requests Staff received a request to paint signage on the bike lane, increase flagging on hydrant, paint curb yellow in no parking zone, and use Park/Rec data on field usage to trigger parking enforcement by PD. Council is aware of the parking challenges related to the splash pad and was presented with an Ardan Park proposal at the last council meeting. Staff looking for direction on process for issues when that issue surpasses any current policy or direction from council.
