CASE 11,/ REVIEW REVISED FEASIBILITY STUDIES FOR SEWER & WATER EXTENSIONS FOR 157TH LANE AND RAMSEY BOULEVARD By: Steven Jankowski, City Engineer Background: Below is a summarized chronology associated with two petitioned requests for the extension of sanitary sewer and water into existing developments: · On July 8, 2005 a petition was received requesting the extension of sanitary sewer and water to nine properties fronting on (or near) Ramsey Boulevard. · On February 14, 2006 a petition was received requesting the extension of sanitary sewer and water along 157th Lane from Ramsey Boulevard east to the cuI de sac. · On April 25, 2006 Council directed that feasibility studies outlining the cost and assessments associated with these projects be prepared. · On July 17, 2006 Bolton & Menk Inc. made a presentation to the Public Works Committee on both of these projects. The project areas along with the project improvements and their costs were summarized. Several options for extending trunk watennain were also presented. The Public Works Committee directed that these projects be discussed at a Council work session. · On January 16, 2007 draft feasibility studies were reviewed and discussed at a Council work session. Direction was provided by the Council on a number of study elements which included; (a) that the connection between 15th Lane and Dolomite street. be an assessable project cost; (b) that determining resident support for the project be determined prior to committing the City to the project costs (This will be accomplished by holding the assessment hearing a minimum of 30 days prior to the authorization of the project.); and (c) that the existing parcels be "ghost" platted to allow for the property owners to determine the potential for the future development of their property, and for the possibility of assr;:ssing on a per developable lot basis. Observations: Although these projects have been shaped considerably by review and direction of the Council, there still remains some uncertainty over a significant project element, that being the location and cost of the trunk watermain which will need to funded' from the utility's trunk fund. It should be noted that there is a degree of interrelatedness between these two projects with regard to the trunk watennain issue. Attached under separate covers are revised feasibility reports for both of these projects. The feasibility study has been revised to show three possible watermain legs which could provide water to the 15th Lane project along with the costs for each of these connections. If both projects proceed the trunk costs for the Ramsey Boulevard leg trunk cost will be reduced by $327,227. Whether one or both of the projects have favorable support for proceeding will likely determine the selection of the trunk watermain route. -187-
