a sewage pump station and short segment of force main at the westerly end of Lot 18. The location and phasing of these improvements are illustrated in Figure VIII-2. Table VIII-4 presents a summary of related cost components, including reimbursement to the developer of Ruby Hill for the previously completed extension of a sewer trunk line within the straightened "S"-Curve portion of Vineyard Avenue. Table VIII-5 contains the sewer system cost allocations. Sewage discharge from single-family housing in the Plan Area is estimated to average 220 gallons per day per unit, or 1.0 EDU . The 12-acre elementary school is expected to generate approximately 4,000 gallons per day, or 18.2 EDU's. Sewage discharge for the park is estimated at 400 gallons per day which translates into 1.8 EDU's . Equivalent dwelling unit calculations are provided in Table VIII-1 for each applicable Plan Area land use. Phase 1 of the sewer improvements includes construction of an 18-inch parallel trunk line from First Street to Bernal Avenue (Sewer Master Plan Section 1), and a 12-inch trunk line from Bernal Avenue to Tioga Court (Sewer Master Plan Section 2). It will also require a ten-inch trunk line extension from Tioga Court to the southwest comer of Lot 8 . This is necessary to avoid overburdening of existing facilities east of Tioga Court. In addition , an eight-inch connector line will be constructed by the City from Vineyard Avenue through Lot 14 to Foxbrough Place to eliminate the pump station and force main which now serve the Foxbrough Estates area. Except for the interim sewer facilities permitted for the school in Phase 2 as outlined in Chapter VI, Phase 3 will require completion of a pump station and force main and extension of the eight-inch trunk line along the new alignment of Vineyard Avenue. 3. Roadway Improvements Shared public roadway improvements within the Plan Area and reimbursement responsibilities for prior roadway improvements benefiting the Plan Area include the proposed realignment of Vineyard A venue between the east end of the straightened "S"-Curve section of Vineyard Avenue and the eastern boundary of the Plan Area (including a traffic signal at the intersection with the loop street which borders the west side of the elementary school), trail and landscaping improvements to the existing Vineyard A venue, reimbursement to the Vista Diablo developer for certain recently completed street improvements along the south side of the Vineyard A venue centerline at the Vista Diablo frontage, and reimbursement to the Ruby Hill developer for straightening the"S"-Curve segment of Vineyard Avenue. Figure VIll-3 illustrates the shared roadway location and phasing, Table VIIl-6 contains a summary of related cost components, and Table VIII-7 contains the roadway system cost allocations. 97
