TSC Minutes-Tracker 4.20.22 MINUTES April 20, 2022 1:30pm – 3:00pm Fountain Conference Room Part I: Call to Order Attendees: X Erik Henricksen X Charlie Howley X George Bender X Stacy Osen X Charlie Burke X Bob Generous X Lance Pearce X Priya Tandon Part II: Review of Action Items from Previous Meetings  Speed Flyers-Review first educational postcard & any follow-up from residents: o First educational campaign in Dakota Ave./Marsh Dr. area-postcards mailed April 6th. o Mailed 238 postcards at postage cost of $126.14 o Be sure to notify front desk and Alison at PW when postcards go out in case increased phone calls. o No calls or responses have come in so far from this one –check w/ communications to see if web traffic increased.  2022 Engineering Intern-Review potential tasks related to TSC: o Possibly help Josh & Ryan with speed trailer o Can review as needed. Part III: Business & Information Agenda Item:  The TSC reviewed Raised Crosswalks (aka speed humps, not bumps) as a potential strategy for enhanced pedestrian crossings. See attached flyer. Generally the TSC supported the general theory of the raised crossing and that they do have a place, however it was clear that there are likely no specific instances or circumstances within Chanhassen that has the pedestrian volume to warrant the use of an elevated crosswalk. The members acknowledged places like shopping malls, airports, colleges, and dense urban situations where this type of improvement could be a legitimate strategy, which are more likely private developments than public right-of-way. The TSC agreed to keep it in the “toolbox” for future consideration if pedestrian volumes would make this a worthwhile use.  Review of Cases:—review cases and assess o The group reviewed case #s 212 - 213 -- Updated to Concern Tracker. o See Attachment for details on these cases. o Erik will work with Alison to update SeeClickFix.  S.A.F.E. Crosswalk Policy: review the crosswalk policy’s draft flowchart for finalization. o Continued work in progress. o Erik will touch base with communications to work on branding/look of flowchart.

The crosswalk is demarcated with paint and/or special paving materials. These crosswalks act as traffc-calming measures that allow the pedestrian to cross at grade with the sidewalk. In addition to their use on local and collector streets, raised crosswalks can be installed in campus settings, shopping centers, and pick-up/drop-off zones (e.g., airports, schools, transit centers). Raised crosswalks are fush with the height of the sidewalk. The crosswalk table is typically at least 10 feet wide and designed to allow the front and rear wheels of a passenger vehicle to be on top of the table at the same time. Detectable warnings (truncated domes) and curb ramps are installed at the street edge for pedestrians with impaired vision. Local and collector roads with high speeds pose a signifcant challenge for pedestrians crossing the roadway. A raised crosswalk can reduce vehicle speeds and enhance the pedestrian crossing environment. FEATURES: • Elevated crossing makes the pedestrian more prominent in the driver’s feld of vision, and allows pedestrians to cross at grade with the sidewalk • Approach ramps may reduce vehicle speeds and improve motorist yielding OFTEN USED WITH: • Crosswalk visibility enhancements Raised crosswalks can reduce pedestrian crashes by 45% !

Raised crossings should generally be avoided on truck routes, emergency routes, and arterial streets. Drainage can be an issue. Raised crosswalks may be installed with curb extensions where parking exists. They may also be used at intersections, particularly at the entrance of the minor street. Since this countermeasure can cause discomfort and noise (especially with larger vehicles), it may be appropriate to get public buy-in. Raised crosswalks may not be appropriate for bus transit routes or primary emergency vehicle routes. For States that experience regular snowfall, snowplowing can be a concern. COST The cost associated with a raised crosswalk ranges from $7,110 to $30,880 each, with the average cost estimated at $8,170. References Federal Highway Administration.

CASE # DATE AREA OF CONCERN SUMMARY OF CONCERN TSC COMMENTS & RECOMMENDATIONS 212 4/7/22 Marsh Drive The posted speed limit when you turn from Lake Drive E onto Marsh Dr. Southbound is 30 mph. This is a residential neighborhood with many small children playing in the streets and there are no sidewalks. The speed limit is too fast for this residential area. Please review the posted speed limit and we ask that you change it to 20 mph. Note a response from another resident regarding Case #194 which was closed out. The neighborhoods in this area were sent an educational campaign in accordance with a previous case which were sent out on April 6th, one day before receiving this concern. The evaluation remained the same that the potential speeders are residents within the neighborhood. The crosswalk identified is being re-striped this year. 213 4/15/22 Carver Beach Road People tend to use the downhill to their advantage and accelerate too fast out of the stop sign heading down toward the lake. There is no sidewalks on this side of carver beach road and many people walk this road. The park is nearby and kids are always running around. Something like a stop sign or speed bump about halfway down would be nice addition to get people to slow down. No improvements are warranted at this time and the issue has been logged for tracking purposes. The city’s practice on installing stop signs and speed bumps are addressed under the Traffic Concerns section of the City’s website . It is recognized that the area does not have sidewalks and the streets are narrow and fairly serpentine which act as inherent traffic calming measures. If there are potential speeders along this corridor, they are most likely residents in the neighborhood. As such, the Traffic Safety Committee will also place educational signs this spring in the area to remind neighborhood residents to drive at safe and reasonable speeds given the conditions.
