as a minimum 20 people/ hour or 15 people /hour with an elderly or school facility near by to be considered for a <br />marked crosswalk. Staff installed a trail camera to capture pedestrian volumes at the intersection for our <br />calculations. The camera was installed the afternoon of May 4th and picked up the morning of May 8th. During that <br />time period staff counted 8 people crossing Variolite St at 161st Ave. The City of Boulder CO has done extensive <br />engineering studies in the area of crosswalk applications and their recommendation is not to install a marked <br />crosswalk at this type of location, as it is configured today. In their studies the Variolite St/ 161st Ave intersection <br />would be rated an E with the following recommendation for treatment "Do not install marked crosswalk at <br />uncontrolled crossing. Determine if the speed limit can be effectively reduced to 40 mph AND a raised refuge <br />median can be installed. If so, utilize Scenario D criteria above. If this is not possible, or if pedestrian volume falls <br />above the RRFB limit line on Figure 2, consider HAWK beacon, pedestrian traffic signal, or grade -separated <br />crossing.Specific Guidance : Consider HAWK beacon, pedestrian traffic signal or grade -separated crossing; <br />application of these treatments will consider corridor signal progression, existing grades, physical constraints, and <br />other engineering factors. ScenaricD reads: Install marked crosswalk with enhanced signs, pedestrian activated <br />RRFBs, and geometric improvements to increase pedestrian visibility and reduce exposure Specific Guidance : <br />Install raised median refuge island (unless it is a one-way street or one already exists) to shorten the pedestrian <br />crossing distance and increase pedestrian visibility to motorists. [If a median refuge can not be constructed on a <br />two-way street, Go To Scenario F]. Install marked crosswalk with "State Law - Yield to Pedestrian" signs WITH <br />pedestrian activated RRFBs mounted on the side of the roadway and on median mounted signs; use standard <br />(W11-2) advance pedestrian warning signs; use S1-1 signs for School Crossing locations. Consider adding <br />neckdowns at the crossing if on -street parking exists on the roadway and storm drain considerations will allow. <br />[Note: If pedestrian volume falls above the RRFB limit line on Figure 2, consider Hawk beacon, pedestrian traffic <br />signal, or grade -separated crossing.] After reviewing the data and comparing it to the recommendations of MnDot <br />and the City of Boulder CO staff recommends that a crosswalk NOT be installed at Variolite St and 161st Ave. <br />Staff also recommends that this area be studied again in 2021 when Variolite street is scheduled for reconstruction. <br />At that time engineering could provide information on the possibility of lowering the grade of Variolite St some <br />what to improve the sight line to the north. Engineering could also provide for the feasibility and cost estimate of a <br />raised refuge median for pedestrians at this location. <br />Funding Source: <br />General fund <br />Recommendation: <br />Staff recommendation is to not install a crosswalk at this location at this time and to restudy this location for <br />possible roadway improvements when Variolite St is scheduled for reconstruction in 2021. <br />Action: <br />Accept staff recommendation or reject the staff recommendation, and accept alternate recommendation based on <br />committee discussion. <br />Attachments <br />May 5th Speed Study <br />May 8th Speed Study <br />
