Definitions/Applicable Code: Applicable Code 2: TRC Section 10.5, Street Lighting “Street lighting should be provided on Spine, Town, Collector and Collector with Trail roads. Refer to Arden Hills Public Works Design Manual for lighting palette. The following standards should apply for pedestrian scale lighting: (a) Vehicular lighting shall be a maximum of thirty feet (30’) in height and pedestrian- oriented lighting a maximum of eighteen feet (18’) in height. (b) Streetlights shall be placed at an average of forty feet (40’) on center, approximately three (3) feet behind the back of curb, aligned with street trees, and where street trees are planted.” Proposed Amendment Request: 1. Amendment to “Applicable Code 2” to provide reasonable and context appropriate light spacing standards per MnDOT Roadway Lighting Design Manual. Practical Difficulty of Meeting TRC: No Lighting along Rice Creek Boulevard: As written, the applicable code appears to allow for an approach where no lighting would be required along Rice Creek Boulevard. However, this approach would not be consistent with best safety practices nor City/County design precedence at the proposed roundabout intersections. The need to provide intersection lighting does not allow for compliance with the TRC through providing no lighting along Rice Creek Boulevard. Providing Lighting (per TRC) along Rice Creek Boulevard: The applicable code (as provided above) would require streetlights to be installed at an average of 40-foot on center for the length of the Rice Creek Boulevard Corridor. Application of this standard would require the installation of approximately 200 streetlights, estimated to cost $2,000,000. A more context appropriate approach to streetlight spacing (~200-ft) would reduce the number of streetlights to approximately 40 lights, or $400,000 in estimated construction costs. Additional Construction Cost: $1,600,000* *Table 3.3 of the TRC does allow for adjustments to “Applicable Code 2” of up to 10%. Maximizing the permitted adjustment would reduce the required streetlights to 180 lights. In this scenario the additional construction cost is reduced to $1,400,000. In addition to the initial capital investment of installing the streetlights, long-term maintenance and operation costs should also be considered. Maintenance and operations costs would be proportionally (per light) more expensive for the more intensive lighting approach. Design Standards/Justification: Roundabout Lighting: MnDOT and FHWA design guidance recommends that all roundabouts be lit to provide adequate visibility for all modes of transportation during non- daylight hours. This guidance is consistent with past precedence for roundabouts constructed by Ramsey County and the City of Arden Hills.
