Christine Mattson Planning Assistant City of Orono 2750 Kelley Parkway Orono I MN 55356 (physical address) PO Box 66 Crystal Bay I MN 155323-0066 (mailing address) S' 952.249.4620 8 952.249.4616 ® cmattson@ci.orono.mn.us www.ci.orono.mn.us Office Hours: Monday- Friday 8 am to 4:30 pm From: Jesse Struve Sent: Tuesday, March 18, 2014 4:49 PM To: Melanie Curtis Cc: Christine Mattson Subject: 20140318 364 West Lake St. #2014-00137 Melanie, I have reviewed the proposed house at 364 West Lake St and have the following concerns: 1. The retaining walls should call out the top of wall (TW) elevation and bottom of wall (BW) elevations. It appears the elevations are abbreviated but this should be confirmed. 2. It appears there are numerous walls that are over 4' in height or the tiered wall exceeds 4' in height and is not separated by 2x the height of the upper wall. Therefore the applicant needs to submit engineered plans and specifications signed by a registered professional engineer for all retaining walls that do not meet height or separation requirements. 3. A swale should be constructed south of the driveway to prevent additional runoff from being directed to the neighboring property. All parts of the driveway should also be directed into this swale. 4. The survey should show how the property is going to connect into the City's sanitary sewer line.
