INTRODUCTION The feasibiliB' study for this project was petitioned by the necessary number of property owners, and certification of the petition was passed by the City Council on November 10, 1992. The purpose of this study is to determine the feasibility and associated costs for the extension of municipal sewer and water service to the lots fronting on 150th Lane N.W. and Helium Sweet N.W. in Pondvale Estates and Pondvale Estates 2nd Addition. In extending service to this area it would coincidentally provide sewer and water service to an additional eight residential lots which are pending final platting within an area approved by the preliminary plat entitled Ramsey Meadows. This project anticipates jointly installing the improvements within the existing subdivision of Pondvale Estates and Pondvale Estates 2nd Addition and the proposed Ramsey Meadows subdivision. Appendix A contains an exhibit illustrating the benefitted area. The improvements anticipated by this project would include sanitary sewer main, watermain, sewer and water services, concrete curb and gutter, bituminous street replacement, storm sewer, tuff restoration and street lights, DESCRIPTION OF EXISTING CONDITIONS The project area consists of 24 platted lots within Pondvale Estates, Pondvale Estates 2nd Addition and a portion of the preliminary plat of Ramsey Meadows which will contain eight single-family residential lots. The lots within Pondvale Estates and Pondvale Estates 2nd Addition are occupied by eight single-family residential lots which are served by on-site sanitary systems and private wells. The street serving Pondvale Estates and Pondvale Estates 2nd Addition consists of a 30 foot roadway with bituminous berm curb. The Ramsey Meadows subdivision is undeveloped land. DE8CRIPTION OF IMPROVEMENTS Sewer and water is proposed to be extended to the prqiect area through a 30 foot permanent easement through the Jones property from where it is anticipated to be available as a result of Improvement Project g92-19. A i2 inch watermain will be extended down 150th Lane N.W. to Helium Street N.W. and down Helium Street N.W. to its northern terminus. An eight inch watermain will be routed down 150th Lane N.W. between Helium Street N.W. and Nowthen Boulevard N.W. A six inch watermain will service 150th Lane N.W. cul-de-sac east of the easement through the Jones property. An eight in sanitary sewer main will service the entire project area. Catch basins will be placed on 150th Lane N.W. approximately one to two hundred feet east of the Pondvale eastern boundary and discharge to a sedimentation basin and subsequently into the DNR Protected Wetland #729-;¢d. The drainage from the northern 300 feet of Helium Street N.W. will be handled in a similar fashion to the existing situation, which consists of a bituminous flume to a drainage easement. The sn'eet is intended to be paved with two inches of bituminous pavement over a four inch gravel base for a width of 30 feet between curb towlines. Surmountable concrete curb and gutter wilt replace the existing bituminous berm curb. Disturbed turfed areas behind the curb will be restored with a minimum of four inches topsoil, fertilizer, seed and mulch. Driveways will be nearly saw- cut and replaced in kin& Six street lights will be installed at intersections and mid-block following consumction.
