1. Specific Plan Sewer System Concept The proposed Plan Area sewer system concept is illustrated in Figure VI-3 and further discussed below . A system of local eight-inch sewer lines presently serves existing development northwest of the Plan Area . Portions of these lines (within Grape Vine and Badger Dri ve s) have no available surplus capacity. Development of Lots 1-17 must therefore pay for a first , approximately 2 ,600-foot long segment of the Section Three Master Plan trunk sewer to bypass this constricted local line. This new ten-inch gravity line will extend from a point on the existing Vineyard Avenue at the southwest comer of Lot 8 in a northwesterly direction to the end of the Section 2 improvements ( opposite Tioga Court). Development on Lots 1-17 will also facilitate the extension of a local eight-inch sewer line south from the new trunk line (through the community park site at Lot 14) to the existing sewage pump and force main at Foxbrough Place . This connection will be completed through an existing off-site easement , and will enhance overall system reliability and capacity by eliminating the sewage pump and force main at this location and by allowing gravity flow through this new line . Sewer lines on Lots 1 , 2, and 3 will gravity flow to the new north-south street on these lots and then north through Vista Diablo. The elementary school on Vineyard A venue may be served by one of two alternative means. First, the school project may front the cost of extending the trunk sewer line and installing the pump station and force main at the western portion of Lot 18. Under this scenario the School District would be eligible for reimbursement of expenditures beyond its fair share cost as other properties develop . Second, an on-site holding tank could be installed, with sewage being trucked off-site until the main line and related improvements are extended easterly to the school. Remaining development within the Plan Area will be dependent on the extension of the eight-inch trunk sewer along the north edge of the Plan Area within the realigned Vineyard Avenue. Development will also need to install the pump station and force main if not already built. 2. Existin& Residences Private septic systems in use for existing residences may continue in use in accordance with public health and safety standards . However, these individual systems shall be abandoned as a condition of the subdivision of the lots on which they are located . Upon connection, existing homes (except for Lots 8 and 15 where prior agreements with the City provide otherwise) will be charged a fair share portion of the cost for new facilities (see Infrastructure Financing Section). 80
