BAY FAIR TOD SPECIFIC PLAN <br />Wastewater Collection and Treatment Improvement Projects <br />There is limited existing infrastructure within <br />the Plan Area; therefore, it is generally <br />assumed that new wastewater collection <br />system backbone infrastructure is needed to <br />serve the entire Plan Area. Figure 7.3 depicts <br />the proposed backbone infrastructure for cost <br />estimating purposes. The proposed collection <br />system can connect to existing trunks at <br />locations approved by the Oro Loma Sanitary <br />District. <br />The pipe sizes and locations are based upon <br />highest demand condition of all the scenarios <br />envisioned in this Specific Plan. A Wastewater <br />Collection System Master Plan should be <br />prepared that identifies specific backbone <br />improvements needed to serve the Plan Area <br />once more refined development plans are <br />completed. <br />In some scenarios, proposed building <br />development would be built over existing <br />sewer trunk on the east side of the Plan Area. <br />In these cases, the trunk must be relocated; <br />therefore a reconstruction cost is estimated. <br />Table 7.4 provides planning level project costs <br />based upon serving the Plan Area with shared <br />backbone infrastructure. Infrastructure cost <br />to serve each development would be borne by <br />future developments. <br />Service for the Hesperian Boulevard corridor <br />is intended to be designed and constructed <br />with development so no costs are provided <br />for these areas. <br />Table 7.4 Wastewater Collection and Treatment Improvements Project <br />EST.
