Box 490 Elk River, MN 55330 RE: FIRST NATIONAL BANK SITE PLAN REVIEW Dear Mr. Ach: As requested, we have reviewed the site plan for the proposed First National Bank facility to be located in the southeast quadrant of Freeport Avenue and 19lst Street within the Elk Park Center Development. The site plan we reviewed was a revised drawing, although it did not contain a revision date. The date of printing in the lower righthand comer of the drawing is September 16, 1994. The site plan was prepared by Hickey, Thorstenson, Grover, Ltd., Architects. Based on our review, we would offer the following comments: 1. The site plan was revised because of two major concerns we expressed to the architects. The fIrst was the method which was used to prepare the grading plan, which did not take into account the existing contours, and the second dealt with storm sewers on the site. The revised grading plan still has major errors in it. As an example, in the boulevard area adjacent to 19lst Street, there is a berm proposed which rises from 933 to a height of 937. Underneath this proposed berm, there is an existing 932 contour which is not adequately dealt with in the grading plan. This 932 contour cannot be left to just hang; it must be shown to wrap around the site in some manner and connect to another 932 contour. Another example of an error on the grading plan is the curb grade along the northeast area of the site. Directly northeast of the proposed drive-thru, there is a spot elevation shown on the curb of 935.0. Approximately 60 feet to the northwest and 60 feet to the southeast, there is also a 935 contour which runs into the curb. This would indicate that the entire length of curb in this area is at elevation 935. In other words, the curb along here is flat and would not adequately drain. Another example of a problem with the grading plan is found in the southern area shown as long range expansion. There is an existing 934 contour on the southern boundary of the property. There is also a proposed 934 contour which runs into the proposed curb. Between these two is a 932 contour which is existing and not adequately dealt with. As it is shown, this would be a low area which would always hold water. Based on these examples of problem areas in the grading plan, we would recommend that the grading plan be revised. 2301247-2201.sep
