This year we are making improvements in the Broback 3' Addition. (See Figures 1 and 2) This area originally was developed without the installation of storm sewer and is a part of the Hawkins Pond drainage area. There is a significant drainage problem at 146t Street where the curb discharges into a flat drainage swale with no outlet. Drainage issues in this area were intended to be accommodated through an extension of storm sewer, but currently only a dry well sump with no outlet is in place. Attached is the Feasibility Report for the Storm Sewer Improvement Project for Broback 3`d Addition, City Project #319. Since the construction item cost is estimated to be less than $50,000, the City, if it chooses, can solicit'price quotes rather than advertising for competitive bids as allowed by newly revised State Statutes. This project would be financed through the Storm Sewer Utility Fund and no costs would be assessed to property owners. At the July 10, 2000 Utility Commission meeting, the Commission recommended approval of the project by Council. Staff recommends the action as stated below.

Page 6 BROBACK 3" ADDITION STORM SEWER FEASIBILITY STUDY CITY OF ROSEMOUNT WSB PROJECT NO. 1235 -002 L INTRODUCTION Each year the City of Rosemount undertakes a certain number of drainage and street improvement projects. The Broback 3r' Addition storm sewer improvements are located between 145` Street and 146` Street between Danville Avenue and Danbury Avenue. This area was developed without the installation of storm sewer and is a part of the Hawkins Pond drainage area. The property owners were previously assessed for the development of Hawkins pond. There is a significant drainage problem at 146` Street where the curb discharges into a flat drainage swale with no apparent outlet. With the development of the 145` Street Improvement Project several years ago, a storm sewer stub was provided to this area with the anticipation of a future extension to the Twin Puddles drainage area. Since that time, the Comprehensive Stormwater Plan has been modified to eliminate the extension of this pipe and provide a different method of out - letting Twin Puddles. Drainage issues in this area were intended to be accommodated through this extension of storm sewer; however only a dry well with no outlet remains. IL PROPOSED IMPROVEMENTS This project proposes to extend an 18 inch storm sewer system from the existing stub at 145` Street to 146` Street, with improvements at the intersection of Danbury Avenue and 146` Street to address settled curb issues. The majority of the drainage issues occur at 146` Street. The existing catch basin off of 146` Street will be removed and replaced with two catch basins on either side of 14e Street, with 18 inch storm sewer extending to 145`h Street. The construction will include three catch basins throughout the length of the storm sewer installation to collect backyard drainage. There are some minor construction issues in the area, including a short segment of fence, some hedges and the temporary relocation of a storage building. In addition, due to the tight construction area, we are proposing the use of HDPE polyethylene pipe, which can be more easily manipulated in this type of an application. This pipe will also allow for the construction to be completed with a tractor backhoe style excavator, and should minimize the amount of restoration.

FINANCING The construction activities are intended to be fully funded through the storm water utility fund, which is established to address drainage concerns, and minor reconstruction projects of this nature. A. Opinion of Probable Cost The summary of the project cost is $60,924.16 which includes a 10% contingency and 28% indirect costs. IV.
