City Engineer, Jesse Struve, visited the <br /> site on February 7, 2013 and has the following comments (see below). The as-built survey cannot be <br /> approved, until his concerns are addressed. <br /> Please don't hesitate to contact us if you have any questions. <br /> Christine Mattson <br /> Planning Assistant <br /> City of Orono <br /> 2750 Kelly Parkway Orono MN . 55356(physical addressJ <br /> PO Box 66 Crystal Bay MN 55323-0066 (mailing addressJ <br /> '� 952.249.4620 g 952.249.4616 <br /> � cmattson@ci.orono.mn.us � www.ci.orono.mn.us <br /> Office Hours: Monday- Friday 8 am to 4:30 pm <br /> OUR OFFICE WILL BE CLOSED: Monday, February 18, 2013 <br /> From: Jesse Struve <br /> Sent: Thursday, February 07, 2013 3:49 PM <br /> To: Melanie Curtis <br /> Cc: Christine Mattson <br /> Subject: 20130207 3095 Casco Pt Rd - 2011-01191 <br /> Melanie, <br /> I performed a site visit to review the as-built survey for 3095 Casco Pt Rd and have the following comments: <br /> • The proposed rain garden was not installed. Instead it was decided to use an existing low area as the rain <br /> garden. This low area is not reflected on the survey. Furthermore, calculations will need to be performed as to <br /> the storage capacity of this area to determine if it will hold at least 232 CF as specified in my 5/18/2012 email <br /> (see attached). <br /> • Since there is snow covering the ground and driveway, it is difficult to determine if any of the driveway is <br /> actually directed to this area. It was also discussed about running roof drains to this area. I will need to see <br /> some sort of documentation that there is a correct amount of area draining to this low area. <br /> • Finally, the approved grading plan showed a swale along the south side of the house. The snow makes it difficult <br /> to see, but it appears this swale was never installed and it is not reflected on the as-built survey. <br /> Jesse Struve, PE <br /> 1 <br />
