MEMO T0: MAYOR AND CITY COUNCy�� FROM: CLERK-ADMINISTRATORCCII:/:/;; DATE: MAY 28, 1987 SUBJECT: WETLAND ADJACENT TO DAILEY KNOLLS AND DRAINAGE SYSTEM During the Council Meeting on May 26, 1987 Mr. John Winiecki, 7575 Groveland Road Northeast raised the issue regarding the detention of water in the wetland directly behind his home adjacent to Silver Lake Road which drains through a culvert under Silver Lake Road and ultimately into the Silver Lake Woods ponds. At this meeting Mr.Winiecki pointed out that when extremely wet weather occurred he was unable to mow his lawn due to the fact that this area held water and he has attributed this to blockage in the culvert and/or ditch system. Staff, prior to this meeting, had reviewed the situation regarding the ditch system on the east side of Silver Lake Road in relationship to a development proposal that had been received by the City for property located at 2708 Trunk Highway 10. This parcel of land and the twelve acres in which it is located, as well as the Kraus Anderson property directly south of the St. Paul Waterworks Line, all drain through a culvert system into the natural area of Silver View Park and ultimately into this drainage ditch system. It was noted by Staff that the system does not currently properly handle the storm water flow from this twelve acre site allowing it to drain into the Silver Lake Woods ponds which were designed to handle this flow. Any cleaning of the ditch should be done in such a manner as to not only drain the wetland area Mr. Winiecki is concerned about but also the other areas that drain into this ditch. Such a project would require additonal engineering work as the matter had only been addressed preliminarily by Staff before Steve Thatcher and Brian Hoffman left our employemnt. As no flooding of private property causing damage to buildings has yet to occur, to the best knowledge of City Staff, we do not feel that this matter is of such major concern that all projects should be realigned in order to reallow this work to occur this year. Also, due to the lack of Engineering expertise on Staff, the City would need to contract with an engineering firm to have an ultimate design of the project done in order that an evaluation may be made of the need to put the project out to bid ohould it exceed the capability of our personnel and equipment. Staff feels that this situation is not dissimilar to the problems we are experiencing in the Ardan, north Ardan area, Edgewood drainage basin area and many other areas of the
