We <br /> have the following comments with regards to engineering matters: <br /> • The plan states that the proposed floor elevations should be verified. We recommend that home <br /> be constructed at the proposed elevations on the plan. It is critical to maintain the basement at <br /> 996.4 to establish two feet of free board from the storm sewer pond emergency overflow. <br /> • This lot was allowed approximately 1180 square feet of wetland buffer impact. The boundaries for <br /> the impact area should be established with signs prior to grading, protected with silt fence and <br /> monitored during construction, and reviewed at final lot grading. At a minimum the signs should <br /> be installed at the intersection of the buffer and north and south lot lines, and at each corner of <br /> the buffer or impact area. This would be six signs in total. A standard detail for the sign is <br /> attached. <br /> • If the un-impacted wetland buffer area has not been established by a native upland seed mixture, <br /> the applicant should be required to submit a planting plan and install approved plantings. <br /> • The applicant should not be allowed to sod any of the un-impacted wetland buffer area. <br /> If you have any questions, please call me at(651) 604-4894. <br /> Yours very truly, <br /> ��-J — �-�--�`-�-� <br /> Darren Amundsen <br /> Cc: Tom Kellogg <br />
