MINUTES CITY COUNCIL FEBRUARY 25, 2015 Keis asked where the storm water would be piped to if one were installed. The City Engineer stated that eventually the water would go into Lake Gervais. The Engineer stated that his concern was with getting the water south of the Boettner house. The Engineer stated that currently run-off is flowing toward the Boettner house. He described the rain water garden that is being proposed by the developer, but indicated that he is requesting that the water be piped from the rain water garden to Keller Parkway and then into a ditch or public storm sewer system. The Engineer stated that the rain water garden is to control both infiltration and rate control. Pechmann asked the size of the pipe. Kotaski estimated that the pipe would be approximately 6 inches in diameter and noted that it is only to direct overflow from the rain water pond. Keis asked if the walking easement could be utilized for this pipe. The City Engineer reported that it could be in the same area, but a separate easement would be necessary for this use of the property. Adele Boettner indicated that she was agreeable with granting an easement for the storm water pipe. Polly Faschinger, 711 Keller Parkway, pointed out that her lot is adjacent to the Boettner property and borders Keller Parkway on the front and LaBore Road on the back. Faschinger was concern that installation of the pipe along her shared lot line with the Boettner property would result in a great deal of tree loss. Faschinger noted discussion at the Planning Commission about tree replacement pointing out that the Planning Commission did not include any such condition in their recommendation. Faschinger also asked where the lake access would be for the second proposed lot. Kotaski indicated that the pipe would be directionally bored; therefore, trees would not be disturbed. Kotaski also indicated that the issue of lake access for the second lot has already been resolved in court and both lots would have lake access via the walking easement. There will be a cross easement granted between the two new lots directing access to the existing easement on the Boettner property. Keis pointed out Boettner's comment that townhomes are being proposed. Kotaski replied that the proposal is for two single-family homes. Pechmann asked where run-off from a pipe would go once it got to Keller Parkway. He was concerned about run-off flowing across Keller Parkway and into the lake causing either a safety or erosion concern. Pechmann asked the volume and flow rate. 4
