BACKGROUND feasibility study on April 11, the financing of the estimated prepared. A three tier with proposed assessment rates has of the city attorney and a The feasibility study evaluates requirements for trunk storm sewer facilities to convey storm water from Footprint Lake to Gerten Pond north of Gervais Avenue. The feasibility study also identifies measures to correct existing serious drainage problems at several other locations within the Footprint Lake drainage area. The report does not address future lateral storm sewer needs. It is proposed to install lateral storm sewers in connection with future street with curb and gutter improvements as an incidental item. The function of the storm sewers identified in this report is to provide protection from flooding due to intense rainfall events. Separate cost estimates have been formulated for the trunk system and the two subareas, which are currently experiencing significant drainage problems. It is feasible to order the construction of the trunk line between Footprint Lake and Gerten Pond alone. It is not feasible to order the miscellaneous improvements alone without the construction of the trunk storm sewer. In the event that miscellaneous improvements were made without the implementation of the trunk sewer, other problems may be created or exacerbated elsewhere in the drainage area. The drainage problems on Cope Avenue have been included in this report since this area also outlets to Gerten Pond. This situation is markedly different in that modifications of the existing storm sewer system are required to remedy existing problems. The recommended Cope Avenue improvements may be independent of Footprint Lake system improvements. Due to the fact that this area was previously assessed for storm sewer and Cope Avenue is an MSA route, it is proposed to finance the Cope Avenue improvements with MSA maintenance funds. FINANCING It is proposed to finance the Footprint Lake system improvements by assessment to property within the drainage area based on square feet. As noted previously, the Cope Avenue improvements in the estimated amount of 858,900 is proposed for funding through MSA maintenance funds. Based upon the implementation of Sherwood Park and Prosperity Avenue storm sewers, in addition to the trunk storm sewer between Footprint Lake and Gerten Pond, as recommended, the amount to be recovered by assessment is 81,385,300.00. A map of the proposed assessment area is attached. Drainage areas 84 and 85, as shown on the drainage map, are not proposed for assessment because they drain directly to Gerten Pond and are not affected by the proposed improvements but were necessary to include in the hydrologic analysis of Gerten Pond. Drainage areas 73, 74, 75 and 76 are not proposed for assessment because they have, for the most part, been previously assessed for storm sewer associated with Knucklehead Lake and the impact of runoff from these areas upon the cost of proposed storm sewers is minimized by ponding in Knucklehead Lake. The following table gives the three assessment classifications proposed with the assessable square feet (i.e. previously unassessed), proposed unit rate, and cost recovery. Assessable Proposed Assmt.

AGENDA ITEM Action by Counoil: Endorsed AGENDA REPORT Rejecte Modified.._,_.,.,,. T0: City Manager Dat FROM: Assistant City Engineer SUBJECT: Edgerton and Roselawn Trunk Storm Sewer System, City Project 85- 08-- Public Hearing DATE: May 13, 1988 INTRODUCTION Subsequent to the submittal of the feasibility study on April 11, 1988, the proposed financing of this project has been reviewed and modified. A three level system of proposed assessment rates has been retained. However, the assignment of various land use classifications to the three categories has been revised as well as the ratio of assessment rates between the three categories in accord with the guidance of the city attorney and a professional appraiser. BACKGROUND The feasibility study was originally ordered in March, 1985 to evaluate means to solve the drainage problems at the Edgerton Ponds located between Ripley and Roselawn. The study was expanded in September, 1987 to investigate the feasibility of providing trunk storm sewer and ponding to facilitate development of the Markfort Addition and other future development on DeSoto Street. FINANCING It is proposed to finance the estimated total project cost of $1,595,000 by assessment against the properties within the drainage area. A map of the drainage and proposed assessment boundaries is included in the feasibility report. Also contained within the feasibility report is a copy of the land use map for reference. The following table gives the proposed land use categories for each of the three assessment classifications with square feet of assessable property (i.e. previously unassessed), proposed assessment unit rates, and cost recovery.
