interoffice MEMORANDUM to: Janice Gundlach, Assistant Director of Community Assets and Development/City Planner from: Craig Schlichting, Director of Community Assets and Development subject: Big Blue Box date: August 12, 2016 The Engineering Department has reviewed the site plan and preliminary grading & utility plans for Northeast Bank and we offer the following comments: Streets-Parking Lot 1. Based on the proximity of the service connection points, the curb and gutter for 1st Street will likely be impacted. The plans should include a new concrete entrance apron to the site, with a concrete gutter swale on 1st. 2. The current entrance does not have a transition curb radius from 1st into the site. With this curb likely being impacted with utility construction, now is the time to rectify this site issue. 3. An easement should be added to the plan covering the 100-year HWL, the easement should include language for drainage, utility and trail purposes. Storm Sewer-Grading 1. All storm sewer utilities within the site are to be considered private and are the responsibility of the property owners for construction and maintenance. 2. A permit may be required from the Rice Creek Watershed District, and it is the responsibility of the owner to obtain if necessary prior to construction. 3. If the RCWD permit is required the site ultimately drains to Jones Lake. Check the current list of impaired waters for Pike Lake for any site specific BMP’s. 4. Provide a detail of the curb cut leading to 1st Street SW. 5. Soil borings conducted for structural design should be forwarded to my attention. 6. The design should include energy dissipating devices near the termination point of the grass swales to prevent impacts to the embankment leading to Jones Lake.
