<br /> <br />Feasibility Report Page 13 <br />Snelling Avenue North and County Road E - Street and Utility Improvements <br />City Project Number PW 20-0100 <br />Based on these work session discussions, the City Council requested staff to consider <br />additional measures that could be incorporated into the design for Alternative 2 to provide <br />additional safety measures for pedestrians using the west shoulder area. The following six <br />strategies should be further developed during the design process. <br /> <br />A. Lane and Shoulder Configuration: In an effort to provide additional pedestrian space <br />along the west side of the roadway, while maintaining the existing 40-ft total road width, <br />the following road section is recommended for consideration during the design under <br />Alternate No. 2: 8-ft wide paved east shoulder, 11-ft wide northbound lane, 11-ft wide <br />southbound lane, and 10-ft wide paved west shoulder. A reduction of the east shoulder <br />to 6-ft wide and additional widening of the west shoulder could be considered during the <br />design process, but good engineering judgement should be used when considering a <br />reduction of the east shoulder width between Skiles Lane and Lametti Lane due to the <br />vertical relief and steeper side slopes along the roadway. <br /> <br />B. Pavement Markings: Due to pedestrian use of the paved shoulder areas and the steep <br />terrain along portions of the roadway, the proposed design for Alternate 2 includes the <br />placement of White Edge Line Pavement Markings along the length of the roadway <br />pursuant to section 3B.6 of the Minnesota Manual on Uniform Traffic Control Devices, <br />including the option for “wide” solid edge line markings. Edge line markings would <br />assist in minimizing unnecessary driving on paved shoulders. <br /> <br />C. No Parking Designation: Parking restrictions along the west side of Snelling Avenue <br />North should be considered to minimize the occurrence of parked vehicles that would <br />require bicyclists and pedestrians to shift out of the shoulder and into the travel lane. The <br />cost of No Parking sign installation is included in the project cost estimate. <br /> <br />D. Shoulder Rumble Strips: Due to steeper in-slope grades along portions of the corridor <br />and the need to minimize vehicle lane departures, the project design should include <br />consideration of rectangular corrugated or sinusoidal shoulder rumble strips in <br />accordance with MnDOT Technical Memorandum No. 17-08-T-02. Special attention <br />should be given to the lateral placement and width of shoulder rumble strips during final <br />design to minimize noise concerns. The cost of rumble strip installation is included in <br />the project cost estimate for Alternative 2. <br /> <br />E. Speed Limit Considerations: A traffic engineering study should be conducted along the <br />corridor during the project design process to determine if a lower speed limit may be <br />justified due to design constraints and limited sight distances for driveways and street <br />intersections. It is possible that the results of the study could recommend a reduction in <br />the current posted speed limit of 40 miles per hour. <br /> <br />F. Speed Display Signs: The placement of speed display signs along the portion of Snelling <br />Avenue/Old Highway 10 north of I-694 have shown some effectiveness with improving <br />compliance with posted speed limits. While the installation of speed display signs should <br />be limited to locations meeting specific criteria, this section of Snelling Avenue North is
