Mccombs Frank Roos Associates, Inc. <br />15050 23rd Avenue North, Plymouth, MN 55447 <br />MEMORANDUM <br />DATE: March 16, 1998 <br />TO: Rick Hauser <br />FROM: Daniel Parks P .E., MFRA Orf <br />SUBJECT: Hauser Residence <br />Background <br />Drainage Calculations for City Variance Request <br />Orono, Minnesota <br />MFRA#11958 <br />Telephone <br />612/476-6010 <br />612/476-8532 FAX <br />Engineers <br />Planners <br />SuNeyors <br />At your request, MFRA has prepared drainage calculations in support of your City Variance <br />Request for the proposed home on Bohn's Point Road in Orono, Minnesota. We understand from <br />discussions with you that the proposed hard cover area in the 75-250 feet zone from Lake <br />Minnetonka is greater than the 25% allowed by City code and a variance is required for <br />construction of the home. <br />According to the Survey prepared by Coffin & Gronberg and the Preliminary Site Plan prepared <br />by Keenan & Sveiven, the lot area within the 75-250 feet zone is 31,900 s.f. and the proposed <br />hard cover in the same zone is 9,524 s.f. or 29.8%. By code the allowable hard cover in the zone <br />is 7,975 s.f., or 25%. Therefore, the hard cover exceeds the code by 1,549 s.f. In order to support <br />the request for the variance, you requested MFRA to prepare drainage calculations and <br />depression schematics to control the excess runoff created by the additional hard cover. <br />An Equal Opportunity Employer <br />J tr
