Item #2: Street Lighting along Rice Creek Boulevard <br />Introduction Statement: The TRC's guidance, as currently written, would either direct the design to <br />include no lighting along Rice Creek Boulevard or alternatively, if lighting is provided, it is required to be <br />at a spacing (40-ft) that is much closer than is typical or desirable for this type of road. The requested <br />amendment would enable appropriate spacing of lighting. <br />Current Applicable Code: <br />TRC Section 10.5, Street Lighting <br />"Street lighting should be provided on Spine, Town, Collector and Collector with Trail roads. <br />Refer to Arden Hills Public Works Design Manual for lighting palette. The following standards <br />should apply for pedestrian scale lighting: <br />(a) Vehicular lighting shall be a maximum of thirty feet (30') in height and pedestrian - <br />oriented lighting a maximum of eighteen feet (18') in height. <br />(b) Streetlights shall be placed at an average of forty feet (40') on center, approximately <br />three (3) feet behind the back of curb, aligned with street trees, and where street trees <br />are planted." <br />Amended Applicable Code (Proposed): <br />TRC Section 10.5, Street Lighting <br />"Street lighting should be provided on Spine, Town, Collector and Collector with Trail roads. <br />Refer to Arden Hills Public Works Design Manual for lighting palette. The following standards <br />should apply for pedestrian scale lighting: <br />(a) Vehicular lighting shall be a maximum of thirty feet (30') in height and pedestrian - <br />oriented lighting a maximum of eighteen feet (18') in height. <br />(b) All lighting shall be placed at spacing adequate to meet Recommended Footcandle <br />Levels as established in Section 4.1.1.3 of the MnDOT Roadway Lighting Design Manual. <br />(c) Vehicular lights shall be placed approximately three (3) feet behind the back of curb. <br />(d) Pedestrian -oriented lights shall be placed approximately two (2) feet away from <br />sidewalks or trails within proposed green space and outside of required clear zones" <br />Practical Difficulty of meeting TRC (Current Applicable Code): <br />No Lighting along Rice Creek Boulevard: <br />As written, the applicable code appears to allow for an approach where no lighting would be <br />required along Rice Creek Boulevard. However, this approach would not be consistent with <br />best safety practices nor City/County design precedence at the proposed roundabout <br />intersections. The need to provide intersection lighting does not allow for compliance with <br />the TRC through providing no lighting along Rice Creek Boulevard. <br />Providing Lighting (per TRC) along Rice Creek Boulevard: <br />The applicable code (as provided above) would require streetlights to be installed at an <br />average of 40-foot on center for the length of the Rice Creek Boulevard Corridor. Application <br />of this standard would require the installation of approximately 200 streetlights, estimated <br />to cost $2,000,000.
