Based on <br />our review, we would offer the following comments: <br /> <br />1. <br /> <br />The preliminary plat and grading plan were prepared by John Oliver and Associates, and were <br />dated February 23, 1993. <br /> <br />2. The plat contains approximately 62 acres divided into 155 lots. ZOning of the area is primarily <br />RIb (single family residential) with portions of the property zoned RId (single (amily residential) <br />and wild and scenic. The development is shown divided into five phases. The first phase is in <br />the northwest portion of the plat adjacent to the Heritage Landing development. <br /> <br />3. The grading plan shows several low points in rear lots which are proposed to be picked up with <br />storm sewer. These potentially could prove to be maintenance problems in the future. A better <br />alternative would be to revise the grading plan to get these areas to drain to the street. <br /> <br />4. There is a low point shown on Riverview Drive (approximately station 7 + 50) which is not <br />shown to be picked up by storm sewer. A revision to the proposed storm sewer system to <br />service this area is required. <br /> <br />5. Sherburne County will require the dedication of an additional 17 feet of right-of-way on CSAH <br />30 (Mississippi Road). Also, two of the three proposed internal streets intersecting with CSAH <br />30 (Fresno and Concord) are relatively steep. The grading plan should be revised to include a <br />less steep "landing" area at these intersections. <br /> <br />6. <br /> <br />The flood plain should be clearly delineated on the preliminary plat. <br /> <br />7. All stonn sewer should be discharged to a sedimentation pond prior to outletting to the <br />Mississippi River. The developer has previously indicated a desire to cooperate with the <br />Heritage Landin~ developers to create a joint sedimentation pond serving both developments. <br />
