I. Introduction City staff has requested this report to determine the feasibility of constructing sanitary sewer improvements for the Webber Hills area, as shown on Figure 1. A portion of the neighborhood is located within the shore'“ind area making it difficult for some property owners to meet the 3-foct separation between the seasonal water table and their septic system. Alternate septic sites are not available on some properties due to lot size and existing topography. The City of Orono conducted a study in 1994 to determine if there were neighborhoods in Orono which should be provided with municipal sewer rather than have the neighborhoods upgrade their existing septic systems. Based on the results of that study, the City of Orono r ,uested approval from the Metropolitan Council to extend sewer to ten Orono neighborhoods. The Webber Hills area was one of the ten neighborhoods recently included in the Metropolitan Urban Service Area (MUSA) boundary expansion. The proximity to she reland, lot size and topography are the primary factors suggesting municipal sewer service is preferable to long term septic system usage. It is estimated that 35% of the existin septic systems in the Webber Hills neighborhood are either failing or non-conforming. Oo Over the past two summers the City has completed sewer projects to serve five of the ten neighborhoods. Webber Hills is one of the next areas on the City ’s priority list for sanitary sewer. This report describes the sanitary improvements required to completely serve the Webber Hills neighborhood. The proposed sanitary sewer improvements are presented on Figures 2 and 3. The costs of the proposed improvements are presented in the appendices and a cost summary is presented in the Cost Analysis section. Webber Hills Sanitary Sewer Improvements
