IL VMbslie: WWW bonestroo com Paul Weinberger Zoning Administralor/Planncr City of Orono Post OfTicc Box 66 Crystal Bay, MN 55323 Stephenson Site Improvements File No. 139-2732 Dear Paul: We have reviewed the proposed grading plan for the Revis and Meghan Stevenson property located on Lot 4, BUkIc 1. Fox Ridge in Section 3. The plans propose to place approximately 3300 cubic yards of fill along an existing slope east of the home. We have the following comments with regards to engineering matters: The proposed improvements include placing approximately 12-feet of fill over an existing utility easement. The purpose of the easement should be identified and a determination made as to whether the fill will impact the use of the easement. A letter from the property owner indicates that a “double** silt fence will be installed to protect the existing wetland. The plans should show two rows of heavy-duty silt fence installed west of the 26-foot wetland setback. All silt fence should be installed prior to any clearing, filling or grading activity. The amount of fill proposed to be hauled to the site will generate a substantial amount of heavy truck traffic. The truck traffic has the potential to damage Fox Ridge Road, an existing City street that serves the neighborhiKHl. We recommend that the City require some type of financial guarantee from the applicant to be used to correct any street damage caused by the contractors activities. The contractor should also provide appropriate traffic control and signing to alert and protect motorists and pedestrians in and near the neighborhood. The City recently completed sanitary sewer improvements to serve the area. A flushing station connection was installed near the northwest corner of the Stephenson property. Some type of fencing or barrier should be constructed around the flushing connection prior to construction to protect against damage. The existing slope where the fill is to be placed is heavily vegetated. The applicant should provide the City with a tree removal and replacement plan as part of the application. The site lies within the Minnehaha Creek Watershed Disuict (MCWD). The proposed improvements could potentially impact the existing wetland located along the cast edge of the propeny. Plans should be submitted to the MCWD for their review and approval. All slopes should be restored with a minimum of 4-inchcs of topsoil and seeded or restored with some type of erosion control measure (wood fiber blanket, etc.) immediately afier the placement of topsoil to minimize erosion potential.
