PE Ms. LaVonne Wilson City of Oak Park Heights 9 P.O. Box 2007 . ,. -. copy Stillwater, MN 55082 Re: East Oaks P.U.D. Our File No. 55 Dear LaVonne: Stevens Engineering submitted a new set of plans for the subject project, dated June 6, 1994, which was delivered to our office on June 9, 1994. The following modifications are proposed: 1. For some unknown reason two new island areas have been added on the entrance road, which restricts lane widths to 16 feet in each direction. 2. The site east of the entrance road has been lowered two feet so that fill would not encroach on the NSP site to the east. This is not necessarily a concern, but the usable rear yards on Lots 11 and 12 have been reduced. 3. The low area on the Greenbriar Apartment site is being filled. Documentation should be provided which shows that this filling is allowed. 4. The pads for Lots 23 through 26 are being lowered one to two feet with the adjacent pad for Lots 21 and 22 being raised nearly three feet. This difference will result in a very steep driveway grade, especially to Lot 22. 5. Lots 21 and 22 are being raised to minimize the height of the retaining wall at the Ramie Johnson Apartment building. Even with the modification, they would physically have to trespass on at least 20 feet of property to the south to construct the wall, assuming 1 to 1 excavation slopes. We have been advised that they do not have permission for this work. 6. The wall along the south property line does not appear to have adequate reinforcement even if permission could be obtained from the adjacent property owner to physically build it. The plan shows slopes at the top of the wall to be 21/2 to 1. This slope is too steep to maintain, so some landscape treatment is required. 2335 West Highway 36 • St. Paul, MN 55113 • 612 - 636-4600 06/26/94 13:43 ECKBERG LAW FIRM + NWAC NO.717 P003 • i • Ms. LaVonne Wilson June 23, 1994 City of Oak Park Heights Page -2- 7. The retaining wall along the east property line appears to be adequate. However, at all wall locations fences should be installed to protect people from falling over the walls. Provisions should also be made at all wall locations to prevent erosion and scour from occurring from storm water runoff cascading over the wall. 8. Some 1V2 to 1 slopes are shown to the rear of Lots 19 and 20, which should not be allowed. 9. We have still seen no evidence that the Department of Transportation has issued a permit for the driveway entrance. 10. Permits are also required from the Watershed District, the Department of Health, and the Pollution Control Agency before construction can take place. 11. The storm water pond has been reconfigured to accommodate the revised grades. The utility plans have also been changed as a result of the grading changes, but are satisfactory.
