MINNSSOTA 58101.1803 March 2$, 1991 24M PA012011 ss Honorable Mayor and City Council City of Lake Elmo, Minnesota Re: Kraft Circle Drainage Problems Lake Elmo, Minnesota Commission No. 9150-001 Dear Mayor and Council: As instructed by the City Council, I visited the referenced problem area on March 27, 1991, Water was ponded on the east side of the road between the south side of Ziniel's driveway and the north side of Wichelman's driveway. According to Mrs. Wichehman, ponding has occurred at this location throughout the 10 years she has lived there. Ptoble The problem appears to be a localized low spot along the edge of the road. Although the Kraft Circle pavement is in good condition, I feel that if the low spot is not drained, the pavement in that area will eventually need patching. I believe that this, in addition to the nuisance the water moos, warrants the City's attention to the problem. Solution It Is recommended that a shallow catch basin be constructed at the low point. An outlet pipe would be extended west across Kraft Circle. A shallow ditch along the north property line of the Rolf property and through the City of Lake Elmo property would be necessary to direct the water to an existing culvert at the corner of 33rd Street lane and 33rd Street (See Fig= 1), — Because of the small size of this project, the City Maintenance Department could perform the construction. It is estimated that materials will cost $1,200, and labor will cost $1,500, A drainage easement will be needed from the `WS for the shallow ditch on their property. Coungg Action It is recommended that the outlet be constructed as proposed. Sincerely, Thomas D. Prow, P.E. TDP/mha
