30 February 6, 2013 Page 6 Sheet C3-1 - Grading Plan 1. All pedestrian ramps within road right-of-way shall be installed per Mn/DOT State Aid standards and shall be constructed with ductile iron truncated domes powder coated red per city standards. 2. The pedestrian ramp located at the southwest corner of 39°i Ave and Apache La should contain an additional ramp to the north. This ramp should be constructed similar to the existing pedestrian ramp located on the southeast corner of the intersection. It should be noted this will require the existing hydrant to be relocated. 3. Add pedestrian ramps at the southwest and southeast corners of the intersection of 39th Ave and the private driveway access located along the west side of the property. These pedestrian ramps should be constructed similar to the existing pedestrian ramps located directly across 39°i Ave. 4. To remain consistent with St. Anthony's sidewalk and street light policy, two decorative street lights will be required. Add one decorative street light along the south side of 39°i Ave NE at the middle of the proposed block and add one decorative street light on the southeast corner of the 39th Ave/private driveway access intersection. This work should be coordinated with Edward Bieging at Xeel Energy Outdoor Lighting, (651) 229-2400. Sheet C4-1 - Utility Plan 1. All ductile iron water mains shall be poly -wrapped per city standards. 2. The St. Anthony Village Fire Department and State Fire Marshall are currently in the process of reviewing the plans. Any additional comments will be forwarded once they are received. Sto•mwater Considerations 1. Salo Pond, the regional pond east of the proposed development has been designed to accommodate runoff from the subject site — both for rate control and water quality. 2. Runoff from the parcel west of the proposed development is also tributary to Salo pond. The original design was to extend the storm sewer through the center of the proposed development to the western parcel. With the proposed building configuration this option is not feasible without placing the storm sewer below the building. However, CB -2 located in the north corner of the proposed parking lot has adequate depth for the future west parcel connection. Storm sewer design calculations should be included in future submittals in order to evaluate downstream capacity. 3. Biofiltration trenches are proposed to provide additional water quality treatment for the site to meet Rice Creek Watershed District (RCWD) Rules. We recommend locating the trenches a minimum of 10 -feet from the building based on Minnesota Stormwater Manual guidance. Please provide a cross section showing the relationship between the biofiltration trenches and building footings. These trenches appear to receive minimal surface runoff from the proposed impervious surfaces and therefore provide limited benefit. 4. Plans must be revised to include the following additional erosion control best management practices (BMPs): • Inlet protection should be provide for all catch basins located on the streets, including catch basins on 39°i Avenue, Apache Lane and 38'x' Avenue on both sides of the street. • A note indicating Contractor shall sweep streets at the end of each working day or as needed to remove sediment and debris. This work may be ordered by City Staff and will be performed at the contractor's expense. 5. Documentation showing NPDES permit coverage must be provided to the City prior to start of construction.
