The easement should <br />be centered on a line located 30 feet south of the south edge of the proposed soccer fields, extending from <br />the east lot line to the proposed 12-inch water main. Permanent and temporary easements should be <br />provided for the Hennepin Parks trail that is scheduled to be constructed this summer. <br />6.
