Christine Mattson <br /> From: Jesse Struve <br /> Sent: Thursday, April 12, 2012 4:05 PM <br /> To: Christine Mattson <br /> Subject: 20120412 3300 Graham Hili Rd <br /> Christine, <br /> To complete the as-built for 3300 Graham Hill Rd,we will need the as-built to include the storm sewer pipe and <br /> discharge location for the drainage structure in the north corner of the garage. The tiered retaining wall was not shown <br /> on the original house grading plan and was installed without engineered plans and specification which is in violation of <br /> City code. <br /> I am willing to waive the requirement of the resident submitting engineered plans and specifications for the wall, but the <br /> resident will need to provide the City with written acknowledgement they are aware of the violation and agree to <br /> assume all future responsibility for a non-compliant retaining wall. The residents should also disclose the wall is in non- <br /> compliance to any future potential buyers. <br /> Please contact me with any additional question or concerns. <br /> Jesse 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 /> From: Jesse Struve <br /> Sent: Monday, March 19, 2012 12:44 PM <br /> To: Melanie Curtis <br /> Subject: 3300 Graham Hill Rd <br /> M ela nie, <br /> I have reviewed the proposed as-built plan submitted for 3300 Graham Hill Rd and have the following comments <br /> regarding engineering matters: <br /> • On the South side of the house, there is a tiered retaining wall. The combined height of the tiers exceeds 4'. <br /> The property owner needs to have a licensed engineer approve the design of the walls, because tiered walls <br /> need to be separated by two times the height of the wall. <br /> • In the north corner of the garage next to the parking bay, there is a drainage catch basin in the grass. Where <br /> does this structure drain? The as-built drawing needs to show the location of the outlet of this structure. <br /> If you have any additional questions regarding the property, please contact me. <br /> Jesse 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 />
