I offer the following comments for your consideration: <br />1. Perimeter erosion control measures (siltfence, biologs, etc.) should be installed by the Contractor and <br />inspected by the City prior to any work. Contractor must provide a minimum 24 hour notice prior to <br />inspection. <br />2. Where areas of existing pavement and buildings are being removed and vegetation reestablished, soil <br />should be de-compacted prior to vegetation establishment. Soil should be disked or ripped a <br />minimum 12" deep. <br />3. Due to proposed disturbance of the majority of the lot, an escrow of $4,000 for erosion control and <br />engineering oversight should be required to provide protection in the event it becomes necessary for <br />the City to install or maintain erosion and sediment control or re-establish vegetation within the <br />project area. <br />4. The applicant may be required to obtain Minnehaha Creek Watershed District (MCWD) approval <br />and permitting for their Erosion Control rule. A copy of any approvals or permits required or <br />confirmation that no permit is necessary should be submitted prior to final approval. <br />Please let me know if you have any questions or need additional information. <br />Sincerely, <br />BOLTON & MENK, INC. <br />ft<Mt~ <br />Robert E.
