Memorandum <br />DATE: February 3, 1999 <br />TO: Mary Kay Wyland <br />FROM: John Powell, City Engineer <br />RE: Lino Lakes Elementary School <br />I have reviewed the preliminary plans for the referenced project which were <br />prepared by John Oliver & Associates, Inc., dated November 24, 1998, and are <br />unsigned. My comments are as follows: <br />1. The City proposes to have utility service available for the school district by <br />September 1, 1999. <br />2. The details of the septic tank and sanitary sewer abandonment are not <br />provided. Filling abandoned pipes is recommended to minimize the <br />possibility of future settlements due to collapsed pipes. <br />3. The utility plan indicates "by others" in various notes. I assume that all of <br />the utility work on site will be under the same contract as the building <br />addition. The City's sanitary sewer and water stubs will terminate at the <br />property line. <br />4. The proposed invert elevation of the 12 -inch HDPE apron west of the <br />addition is 912.18 whereas the proposed contour at the outlet has an <br />elevation shown of 913.0. <br />5. The City has obtained temporary easements near the east and west <br />driveways to be used during the installation of utility stubs. These <br />easements are not shown. <br />6. The west water connection should extend to the building instead of <br />terminating at a hydrant such that the facility can be fed from one City <br />water stub or the other. <br />1189 Main Street • Lino Lakes, Minnesota • 55014 <br />Phone/TDD: 651 -464 -5562 • Fax: 651 - 464 -4568 <br />
