CITY MANAGER'S APPROVAL: No comments to supplement this repo omments attached Recommendation: To approve contract F na ayment, Partial Payment 4 for City Project 12-9, Freedom Park Phase I Flood Mitigation Improvements to Midwest Asphalt Corporation in the amount of$6,467.88. Legislative History: August 23, 2011 City Council authorized staff to enter into a contract with WSB & Associates for engineering services for the preparation of our Surface Water Management Plan(SWMP) and a July 2011 Flood Report. April 24,2012 The Flood Report was accepted by City Council Meeting and the City Council authorized City Project 12-9,Phase 1 Freedom Park Flood Mitigation Improvements. July 6, 2012 Council approved plans and specifications and authorized advertisement for bids. August 7,2012 Bids opened by staff. August 15,2012 City Council awarded contract to Midwest Asphalt Corporation. Financial Impact: Please see attached payment breakdown for details. Explanation: City Project 12-9 consisted of expansion of the pond in Freedom Park into areas south and west of the existing ball field. This will increase flood storage available for high intensity rainfall events and reduce the probability of flooding at downstream locations. In addition, the first phase included construction of additional catch basins along Pike Lake Drive at Fredeen Court and 12th Street. These catch basins will provide additional capacity to allow surface water to enter storm sewer under these intersections, which can reduce the potential for flooding at these intersections. To allow for the additional capacity collected by the new catch basins,the 30-inch corrugated metal storm sewer pipe discharging to Pike Lake (from Pike Lake Drive and 12th Street)was removed and replaced with a larger 54-inch concrete pipe. All contract work with Midwest Asphalt Corporation for City Project 12-9, Freedom Park Phase I Flood Mitigation Improvements has been completed and accepted by City staff. This payment includes payment on all contract final quantities and Change Order items associated with the project. It also releases all payment retainage. The wet spring prevented seed from growing in the bottom of the Freedom Park pond. The City will save money by reseeding this basin with City forces during the fall growing season. Additionally, we will add a storm water collection device to address drainage entering the basin from the townhomes to the south.
