CC Regular Session 4. 2. Meeting Date: 09/25/2012 By: Len Linton, Engineering/Public Works Information Title: Receive plans and specifications and authorization to bid City Project #12-28 Rum River Hills Storm Sewer Improvements Background: The City experienced several significant rainfall events in 2011 lead to many localized flooding concerns and resident complaints. Throughout that summer and fall staff worked hard at registering and responding to the calls, and evaluating the situations on an individual basis to determine whether quick fixes could be implemented (culvert obstructions, re -ditching, etc.) to alleviate the immediate concerns. This item was discussed at the Public Works Committee on August 15, 2011, and at that time staff summarized the areas of concern that were being investigated based upon citizen complaints received. The attached summary was presented at the meeting; which outlines the concern identified, actions steps to evaluate the concern, additional investigations that would be necessary to fully understand the situation, and recommendations for specific projects that could be implemented rather quickly and inexpensively. At that time we classified the issues into 3 categories: 1. Those that required no further action. They were evaluated and corrected, or did not need correcting because the water was fully contained within a dedicated drainage & utility easement (functioning as designed). 2. Those that required additional investigation and evaluation before deciding on a long term solution, and implementing corrective actions. 3. Those that had an identified recommendation for immediate action. Throughout the winter areas in the second category were investigated, evaluated and brought forward for approval of plans for corrective actions. The stormsewer modifications at Rum River Hills Golf Course are the latest improvement to be reviewed by the Public Works Committee. Notification: The Golf Course representatives will be notified that the project is being considered for advertisement for bids. Observations: Rum River Hills Golf Club is located east of Trunk Highway 47 at 167th Avenue NW. Several areas were evaluated and summarized in the report. The golf course was platted in the early 1980's, and at that time linear drainage and utility easements were secured on the site to encumber areas where off -site stormwater was routed through the site. Many areas of the site experienced flooding concerns last summer, and they were summarized at the May 15, 2012 Public Works Committee Meeting. A motion was made to recommend preparation of plans and specifications for storm drainage improvements at Rum River Hills Golf course. Hakanson Anderson has prepared the plans and specifications and their design will be presented tonight. Four areas were identified as need improvement, each will be discussed in detail along with the proposed improvements. Area 1 (Pond adjacent to Hole #1)
