HomeMy WebLinkAboutSP-22-006 - Supplemental - 1459 Shelburne Road (53)1 Marla Keene From:Dave Wheeler Sent:Tuesday, February 22, 2022 11:50 AM To:Marla Keene Subject:RE: SP-22-006 1459 Shelburne Road Homestead Preschool - technical review Hi Marla, The Stormwater Section has reviewed the “Homestead School – Proposed Infant Care Facility” site plan prepared by Krebs & Lansing Consulting Engineers, dated 2/4/2022 and most recently updated on 2/15/22. We would like to offer the following comments: 1. Revise stormwater system to Tier 2 bioretention system. 2. Revise emergency spillway detail so that the bottom of stone is not 6” below the surface of the basin. 3. Confirm that the berm along the west side of the site can tie into the dumpster pad in such a way that stormwater is not bypassing treatment. Consider adding a portion of curbing if needed. 4. Only a portion of the drainage area is routed to the forebay, include additional pre-treatment for remainder of area, such as a stone diaphragm. 5. Confirm if roof on property to the north drains into the grass swale. 6. Revise grades so that water does not puddle in corner of parking spaces at elevation 156, in curbed area. 7. Consider adding a removable screw cap on underdrain outlet to potentially clear 1” orifice. 8. The DRB should include a condition requiring the applicant to regularly maintain all stormwater treatment and conveyance infrastructure.
