The plans propose to build <br /> a single family home and attached garage. We have the following comments with regards to <br /> engineering and erosion and sediment control matters: <br /> • More detailed information, such as grading, draintile inverts and locations, piantings, and <br /> section information, should be provided for the proposed rain gardens. <br /> • Provide additional location and elevation information for the existing home north at 1101 <br /> Ferndale Road. Along with that information, provide additional topo showing the <br /> driveway for 1101 Ferndale. The goal would be to determine if a closed basin exists and <br /> its EOF elevation relative to the home at 1101 Ferndale. <br /> • The north and south side of the driveway currently drains through a 6-inch PVC pipe to <br /> the north across 1105 Ferndale Road. The applicant should submit storm water <br /> calculations showing the existing and proposed conditions draining to the north. <br /> • Show the 6-inch storm sewer pipe and any structures to the lake. <br /> • Floodplain mitigation calculations should be submitted for review. <br /> • All removals should be labeled. <br /> • This project will need approvals from the U.S. Army Corps of Engineers for the flood plain <br /> modifications and Minnehaha Creek Watershed District. - <br /> • Shoreline stabilization should be shown on the plans. <br /> • This project will disturb more than 1 acre of land and requires a MPCA NPDES permit. <br /> • The Storm Water Pollution Prevention Plan must also meet the requirements set in <br /> Orono's Land Use Code Chapter 79, Section 79-7(c)(2). � <br /> If you have any questions, please call me at(651) 604-4894. <br /> Yours very truly, <br /> /1�\�-- 1 . �.lG� <br /> Darren Amundsen <br /> Cc: Tom Kellogg , <br />
