Wl <br />Website; www bonestroo com <br />H <br />We have reviewed the preliminary grading plan for the proposed new home construction at the Peter Boynton <br />residence. The site is located at 1973 Fagemess Point Road in the northeast quarter of Section 18. We have <br />the following comments in regards to engineering matters. <br />1.Access: The drawing submitted for our review contains a lot of information and is difficult to understand <br />at times. It is unclear whether the proposed driveway will be paved or gravel. We recommend the new <br />driveway be bituminous or concrete to prevent sediments from washing to the lake. <br />2.Grading: The grading plan shows the site being lowered by approximately 4 feet near the middle of the <br />site. The proposed plans indicate grading up to the lot lines of the neighboring properties on both sides <br />of the Poynton property. The size of the existing lot and the amount of proposed grading may impact the <br />neig' joring properties and might require easements. The grading plan shows a 944 contour Qring into a <br />946 contour along the northeast lot line, plans should be revised and corrected. Proposed contours <br />northeast of the garage scale 2:1. We recommend that slopes that will be maintained not exceed 3:1. <br />Erosion control is a big concern as the lake borders two sides of the property. An erosion control plan for <br />the entire site should be submitted for review. Erosion control measures should be in place prior to any <br />grading and maintained throughout construction until vegetation is established. <br />3.Drainage: Impacts to the lake should be minimized. Phosphorous loadings leaving the site should be <br />limited to a maximum of 0.28 pounds/acre/year. The site lends itself to some son of best management <br />practice (BMP) such as vegetated buffer strips to treat runoff leaving the site. <br />4.Easements: Drainage and utility easements should be provided 5 feet wide along all interior lot lines and <br />10 feet wide along the roadway right-of -ways. <br />Please contact me at (604-4863) if you have any questions regarding this matter. <br />Yours very truly, <br />BONESTROO, ROSENE, ANDERLIK & ASSOCIATES, INC. <br />/<T?r^ <br />Tom Kellog <br />Cc; Greg Gappa, City of Orono <br />2335 West Highway 36 ■ St. Paul, MN 55113 • 612-636-4600 • Fax: 612-636-1311
