Jesse Struve <br /> From: Jesse Struve <br /> Sent: Monday, August 13, 2012 1:44 PM <br /> To: Melanie Curtis <br /> Cc: Christine Mattson <br /> Subject: 20120813 2280 Fox Street 2012-00728 <br /> Melanie, <br /> I have reviewed the application for the proposed addition on the house and have the following comments: <br /> • There is a wetland classified as "Preserve" which covers the northern portion of the property. This project will <br /> disturb more than 50 cubic yards of material and will trigger Orono's wetland buffer requirements. Therefore, <br /> the applicant will need to get a wetland delineation performed and approved by the City's consulting engineer <br /> Bolton & Menk. <br /> • With a preserve wetland,there is a required 50' buffer and 20' structure setback(70'total from edge of <br /> delineated wetland boundary). The applicant will either need to plant a new buffer zone or have the existing <br /> buffer(if there is one) inspected and approved by Bolton & Menk. The survey needs to be updated to reflect <br /> the buffer and structure setbacks. <br /> • The current retaining wall plan does not show walls which exceed 4' in height. If changes are made and the wall <br /> exceed 4' in height or if tiered walls exceed 4' in height and are not separated by more than 2x the height of the <br /> walls (measured from the face of the upper wall to the back of the lower wall), the applicant will be required to <br /> have the walls designed by a registered professional engineer. <br /> • The survey should show the erosion control and there will be a $2,000 escrow associated with the erosion <br /> control. <br /> Please contact me with any questions or comments. <br /> lesse Struve, PE <br /> Director of Public Works/City Engineer <br /> City of Orono <br /> (952) 249-4661 - Direct <br /> (952) 249-4616- Fax <br /> www.ci.orono.mn.us <br /> 1 <br />
