Box 2007 Stillwater, MN 55082 Re: Dr. Daniel and Lois Hall's Complaint Swager Brothers 9th Addition - Pond Overflow City of Oak Park Heights File No. 55 Gen. Dear Ms. Wilson: In May of 1989 the Halls requested that the city evaluate and remedy the prob- lem of water overflow from the Swager 9th Addition pond onto the southeast portion of the property owned by Dr. Hall. After inspecting the site we came up with several alternatives to remove the water from the Hall's property. 'le are only presenting these alternatives and not making any recommendations, because the city's budget for this issue is not known. The first alternative involves ditching or piping water from the overflow area to the south, across state owned land which is managed by the Department of Natural Resources (DNR). This alternative would lower the high water level and solve the problem with minimal cost. We contacted the DNR in October and supplied them with the proposal and information necessary. They were not very responsive or interested in helping the city with this problem. We pursued this alternative further and scheduled a meeting with the DNR on Friday, January 26, 1990, at the job site. The DNR was more responsive this time but 7. wanted the city l all other noss bl a alternatives. T e main t aey wsn��a ... C1.t� to evaluate oil C�.i12� N ..oai.,�c, main issue for them was the reduction of existing wetlands. They even hinted that whatever reductions were made would have to be replaced at the city's expense. The second alternative would involve filling the portion of the Hall's yard with off -site material. We estimate it would take eight hundred and thirty cubic yards to fill the natural depression within the lot lines of the Hall's property. The cost of this alternative would be approximately five thousand dollars, assuming six dollars per cubic yard for the material. The last alternative involves doing nothing. There is a case for this, be- cause the Hall's property has remained unchanged from the time prior to the construction of the Swager 9th Addition. The only difference is that the pond created in 1987, as part of the Swager 9th Addition, reduced the size of the Page 1. 2335 West Highway 36 • St. Paul, Minnesota 55113 • 612 - 636 -4600 , . to so Ms. LaVonne Wilson March 29, 1990 City of Oak Park Heights Re: File No. 55 Gen. overflow area. Further surveying showed that the natural overflow for this area is at the same elevation as the foundation for the shed on the south side of their house. The basement of the house is 1.2 feet above this critical elevation and would not be in danger of flooding. Based on the alternatives listed above, the city should have enough informa- tion to make a decision on this matter. If you have any further questions, we would be happy to discuss any information at your convenience. Our phone number is 636 -4600. Yours very truly, BONESTR00, ROSENE, ANDERLIK & ASSOCIATES, INC. F.
