MN 55323 <br />Re: Bentrott Site Plan <br />File No. 139-GEN <br />DearLiz: <br />We have reviewed the site plan dated October 7,1998 for the proposed garage relocation on the Brent Bentrott <br />property. The site is located at 1453 Park Drive on the south side of Forest Lake in the south half of Section <br />7. We have the following comments in regards to engineering matters <br />1. Grading: The proposed grading plan appears to present some problems. The proposed slopes north of <br />the driveway at the south end ol the iot scale to 2:1. We recommend the maximum slopes be 3:1 so they <br />can be maintained. The proposed swale east of the driveway is within 6-feei of the lot line and as close <br />as 7-feet to the neighbor’s garage. It may be necessary to obtain additional easements to construct the <br />driveway and swale. The grading plan appears to make the existing drainage situation worse by directing <br />water towards the existing home and proposed garage. We would recommend revising the grading plan <br />so that drainage is directed away from sLoicniies. The proposed retaining walls exceed 6-feet in height <br />in some locations. Retaining wall details and design should be submitted for review. <br />2. Drainage: A detailed drainage area map of the contributing drainage area and drainage calculation.s <br />should be submittea for review. <br />3. Easements: Utility easements should be showTi 5-feet ^v•ide along the ’.nterior lot line. Drainage easements <br />should be provided across all drainage ways. <br />4. Financial Guarantee: When the plans have been completed we will prepare an estimate of the total cost <br />for the site improvements to determine the amount of the financial guarantee required. <br />Please contact me at (604-4863) if you have any questions regarding this matter. <br />Yours very truly. <br />BONESTROO.
