EN HILLS MEMORANDUM DATE: September 19, 2011 TO: Honorable Mayor and City Councilmembers Patrick Klaers, City Administrator FROM: Terry Maurer, Public Works Director Michelle Olson, Parks and Recreation Manager SUBJECT: Valentine Park Improvement Update Background The Valentine Park Improvements were last before the City Council at the June 13, 2011 Meeting. For your information the council memo (Attachment A) and the minutes (Attachment B) from the June 13, 2011 meeting are attached. Since June a detailed drainage design relative to the neighborhood draining through the park to Valentine Lake has been completed. It has been determined that a park and a drainage system can co -exist on the property and can be constructed in such a manner as to protect the park amenities and adjacent properties. In general this will be accomplished by constructing a plateau at approximately elevation 882 which will contain the park amenities and parking lot. This area will still be almost two feet below the lowest home opening adjacent to the park which is at elevation 883.91. The remaining park property will be used for a detention pond, rain garden sized to accommodate a large portion of the neighborhoods requirement when the streets are reconstructed and a large grass area. At the June 13 meeting there was a question about where to place the park amenities; on the western side of the park nearer the adjacent homes or the east side of the park nearer the street. Attached are two conceptual drawings (Attachment C) showing the same park amenities, detention pond and rain garden. Staff is looking for direction on the general layout of the park/drainage improvements. A more specific cost estimate has been prepared by design item since the final layout has not been finalized yet. The cost estimates is as follows: City Council Meeting \\ Metro- inet. us \ardenhills\PR &PW\Parks\Memos \Council Memos \091911 ValentineParkMemo.doc Page 1 of 3
