I. Introduction <br />The City Council has requested this report to determine the feasibility of constructing sanitary sewer <br />improvements for the Bay Ridge area, as shown on Figure 1. The lots in the area are generally small <br />and it is difficult for the homeowners to provide a suitaole area for replacing their on-site systems. <br />The City of Orono conducted a study to determine if there were neighborhoods in Orono which <br />should be provided with municipal sewer rather than have the neighborhoods upgrade their existing <br />septic systems. Bay Ridge was one of the ten identified Orono neighborhoods designated as “rural ” <br />(unsewered) area. <br />The smaller lot sizes, proximity to lake shore and other factors suggest municipal sewer service is <br />preferable to long term septic system usage in the Bay Ridge area. It is estimated that 45% of the <br />existing septic systems in Bay Ridge will need to be upgraded. <br />The City has held neighborhood meetings with the residents to attain input and develop a workable <br />solution for solving the problem. The Bay Ridge residents have requested sewer, conditioned on a <br />lake side location. <br />This report describes the sanitary improvements required to completely serve the development. The <br />proposed sanitary sewer and force main improvements are presented on Figure 2. The costs of the <br />proposed improvements are presented in the appendices and a cost summary is presented in the Cost <br />Analysis section. <br />Sanitary Sewer Improvements
