installed, spacing shall be such that when the center bollard is removed, a 10 -foot <br />maintenance or emergency vehicle access width is available. When multiple bollards are <br />used, a central bollard shall always be placed on the centerline of the facility. Bollards <br />shall comply with the Manual on Uniform Traffic Control Devices (MUTCD) guidelines and <br />conform to City Standard Drawing TM820(B) for removable bollards. <br />B. Clearance <br />The minimum vertical clearance from obstructions (structures, signs, trees, etc.) above <br />shared use paths is 9 feet. <br />C. Cross -Slope <br />The cross -slope for shared use paths shall not exceed 2 percent. <br />D. Grade <br />Longitudinal slope of shared use Paths shall not exceed 5 percent. Where compliance is <br />not practical due to existing topography, infrastructure, right-of-way availability, a <br />notable natural feature, or similar existing physical constraints, the Project Engineer may <br />submit an application for a deviation. <br />Grade breaks may be used when the grade change at a station is 2 percent or less, except <br />grade breaks at driveways and access ramps shall meet the design standards for those <br />facilities. For paths less than 8 feet wide, grade breaks may be up to 5 percent. <br />E. Intersections <br />All shared use path intersections shall be designed to accommodate the maintenance <br />vehicle (type and dimensions to be provided by the City) for all turning movements within <br />the paved surface. The minimum radius for any corner shall be 15 feet. The shall provide <br />documentation demonstrating the design vehicle can navigate all turns within the paved <br />surface using vehicle turning movement modeling software (i.e., Auto -turn or equivalent). <br />F. Lighting <br />All new shared use paths shall include LED lighting. The design shall include a lighting <br />analysis based on an average maintained illuminance level between 0.7 and 1.0 <br />footcandles. The Design Engineer may also layout the luminaries in accordance with the <br />spacing table provided below. The design shall comply with the Design Standards for <br />Street Lighting Systems located in Appendix G, the Standard Specifications and Drawings, <br />and the applicable lighting requirements provided in Section 2.05. <br />Public Improvement Design Standards Manual, 2016 Page 2-4 <br />
