homeowners for these easements. Many projects in other communities have successfully obtained easements without compensating homeowners by asking for volunteers. Homeowners who wish to have a raingarden installed in their boulevard have come forvvard in great enough numbers to adequately serve the project area. This kind of cooperation can be fostered by holding informational meetings and by distributing pamphlets and other materials outlining the attributes of these amenities. A cross section of the proposed infiltration basins is shown in Figure 9. Sanitary Sewer Since the City has chosen to make an investment in its streets, it is important that everything underneath those streets be checked to ensure the street investment is not compromised by the future need to repair infrastructure below. The existing conditions of the sanitary sewer system were evaluated through the examination of the City's regularly scheduled sewer televising program. The reports produced from these video inspections were analyzed for deficiencies including mineral deposits, open or offset joints, sagged, cracked, or fractured pipe, Recommendations for the rehabilitation of the sanitary sewer system are included below. Repairs are proposed based on the severity of the problem and the need for that problem to be fixed via open-cut methods. Issues which could be repaired with in-line technology have not been included since their repair can be completed at any time, without disturbing the pavement. REPLACING AND REPAIRING PIPE Throughout this proposed project area numerous sags in the pipeline have been identified. The most severe of these sags hold four inches or more of water. It is recommended that these more severe sags be removed and replaced while the roadway is under construction. The only way to fix sags in the pipe is by excavating them and relaying the pipe. Other, smaller sags have been identified throughout the project area, These hold less than four inches of water and are noted on the following figures. These smaller sags are not recommended to be removed and replaced at this time, With regular maintenance, pipe with small sags can still function although with some capacity compromised. MANHOLE REHABILITATION A few manholes requiring attention were noted in the analysis of the televised tapes. A few of the common issues requiring rehabilitation are: . Waste concrete blocking flow, . Un-grouted connections that allow infiltration, and . Manholes holding water. it is recommended that these manholes be repaired to meet current city standards.
