McCaffrey vc S I <br /> 9480 Aspen --c c T <br /> V2` nk, <br /> Eden Prairie, MN 55344 <br /> 4400 <br /> Re: Driveway Plan or Lot 7, Block 1, Orono +aks <br /> Dear Mr. McCaffrey: <br /> City Engineer Glenn Cook has reviewed existing plans for your proposed <br /> driveway at 1225 Orono Oaks Drive. He feels that no further plans are <br /> needed. However, regarding the elevation of the invert of the culvert that <br /> will be placed under the driveway, he notes that no outlet invert elevation <br /> was given for the culvert that is east of your property and under the Luce <br /> Line Trail. His comment was that if the outlet invert of that Luce Line <br /> culvert is at 952,0 feet or higher, then the proposed driveway culvert <br /> invert elevation of 951.5 feet is acceptable. However, if the Luce Line <br /> culvert invert is lower than elevation 952.0 feet, then your driveway <br /> culvert should be lowered to elevation 951.0 feet or to whatever elevation <br /> will yield a driveway culvert invert approximately 6 to 12 inches below the <br /> Luce Line culvert invert. Your excavator can verify these elevations when <br /> he is setting that culvert. <br /> Based on the drawings submitted previously, I am estimating your fill <br /> required at approximately 750 cubic yards, hence this project qualifies for <br /> the lesser grading permit fee of $50.50. Your grading contractor should <br /> obtain that permit prior to commencement of excavation. <br /> Please feel free to call me at 473-7357 if you have any questions. <br /> Sincerely, <br /> 97/4;4_0/r' <br /> Michael P.
