The Council directed the Engineer to investigate the situation. Background In 1984, the City awarded a construction contract to Forest Lake Contracting for the reconstruction of 45th Street. Julep Avenue, and 47th Street from Jane Road to Keats Avenue. The contract called for a certain amount of fill soil to be furnished by the contractor. The contractor negotiated with John Berschens to obtain this soil from the powertine easement which was owned by Berschens but wasn't being tilled. This area is west of the Friend and Petrellis property and at a higher elevation. It is my recollection that no property east of the powerline was disturbed. Analysis Since we could not determine where the drainage breaks were by eye, we took some elevation shots on the Berschens property. The attached diagram shows that about 3 acres of Berachens property drains west while the remainder drains east, It is also interesting that the west edge of the powerline easement is about 10, - 15' lower than the east edge of the powerline easement, The land slopes gradually to the south burmore steeply to the west. Friend owns Lot 1 and the south 1/2 of Lot 2. Petrellis owns Lot 3 and the north 1/2 of Lot 2, The drainage runs west toward Lake Jane on the common line between these two properties. The property owners are concerned about erosion and that the drainage may affect a septic system, Solution Since the land gradually slopes to the south, a berm could be constructed on the west line of the powerline easement to direct the runoff to the 45th Street road ditch. The water would then run along the south line of Friend's lot to Jane Road. I believe a berm was constructed by Forest Lake Contracting in 1984 but may have since been overtopped and eroded through. I will be meeting with the property owners Monday afternoon so I will have a report at the Council meeting. If tine Berschen's site were s�%�6 9lJL�1➢ i�d'ublic Works facility, this berm could
