<br />. <br /> <br />. <br /> <br />. <br /> <br />Elk Ridge O:nter 2nd Addition <br />October 21,2005 <br /> <br />Page 2 <br /> <br />should be noted that the relocated storm sewer is shown to be placed between an <br />existing retaining wall and the south line of the proposed building with virtually no <br />space. It is unclear how this storm sewer can be built in this area without potentially <br />damaging the existing retaining wall or being in the way for the footings of the new <br />building. <br /> <br />5. A Storm Water Pollution Prevention Plan (SWPPP) was included with the submittal <br />package. The City now requires SWPPP's tobe in an 8 ~" x 11" format, signed by the <br />owner, developer and contractor. The SWPPP that was submitted is incorrect in the <br />statement that the City of Elk River will have responsibility for long-term operation and <br />maintenance of the Pavement Storm Water Management System. The storm sewer <br />system internal to this project will be considered private, since it drains a private <br />property. The SWPPP should include details regarding installation of silt fence, rock <br />construction entrance, inlet protection and other necessary erosion or sediment control <br />devices. The City has prepared a generic SWPPP, which can be used for this project. A <br />NPD ES permit will be required and either documentation that new permit has been <br />applied for or the existing permit has been transferred to the parties involved with the <br />second phase will be required. <br /> <br />6. It should be noted that there are several items remaining on the punch list from the first <br />phase. It should be a condition on this phase that all items on the punch list from the <br />first phase be completed before any work is started on the second phase. <br /> <br />If you have any questions regarding any of these comments, please call. <br /> <br />Sincerely, <br /> <br />~' <br />/~pt~ <br /> <br />T eny J.
