e Mr. Steve Ach June 15, 1994 Page Three 9. With the large amount of vehicle traffic which would be anticipated with this type of commercial development and anticipating future commercial development to the north, consideration should be given at this time to adding a left turn lane from I93rd Street to Evans Avenue. A portion of I93rd Street is in the process of being reconstructed as part of the extension of trunk sewer and water utilities to this location. It would be easy to add additional work in this area by change order. C. Grading and Drainage Plan e e 230/226-1503.jun 1. The grading plan shows grading off of the project site to the west in the MnDOT highway right-of-way and slightly off the project site to the north onto private property. A permit from :MnDOT will be required for this work in the right-of-way and permission from the owner to the north will be required for the work in this area. 2. There are two low areas shown on the grading plan outside of the pond which should be investigated for wetland determination. One is located in Lot 1, Block 1, and the other is located in Lot 1, Block 2, just off the southwest corner of the proposed building site. 3. Additional spot elevations should be provided on the grading plan to indicate how the parking lot will be graded to facilitate drainage to the proposed catchbasins. Currently, there are catchbasins placed between elevations 956 and 954 where it does not appear drainage will be directed toward the catchbasin. 4. During the construction of Hillside Estates Addition, stumps were allowed to be buried adjacent to the west side of the plat. A determination needs to be made whether or not these stump burial sites will interfere with the proposed construction on the east side of this commercial development. The Developer should specifically locate these sites and show them on the plan. 5. The ponding area in the southeast corner of the site has two sides which include a step-down retaining wall of approximately two 6-foot steps followed by approximately 9 feet of rock for erosion protection at a 1: 1 slope. The other two sides are graded down at a 3: 1 slope. This is a fairly deep pond which will maintain a normal pool of water 4 feet deep. If additional grade cannot be provided to a 4: 1 minimum slope, the pond should be fenced. The concern is one of safety. If an individual were to somehow fall into the pond, there needs to be a side slope flat enough that the person can get out of the pond.
