Hacienda TOD Standards and Design Guidelines Initial Study d) 1 lave sufficient water supplies avail tblc to serve the X project from existing entitlements and resources, or are new or expanded entitlements needed? e) Result in a determination by the wastewater treatment X provider which serves or may serve the project that it has adequate capacity to serve the project's projected demand in addition to the provider's existing commitments? f) Be sen-ed by a landfill with sufticier t permitted capacity X to accommodate the project's solid waste disposal needs? g) Comply with federal, state, and local statutes and X regulations related to solid waste? The City of Pleasanton currently supplies domestic water to Hacienda. The Dublin San Ramon Services District currently treats wastewater from Hacienda at its treatment plant near 1 -680 and Stoneridge Drive. Wastewater collection facilities within the City limits are maintained and operated by the City of Pleasanton. The Pleasanton Garbage Service provides refuse disposal to the project vicinity through a franchise agreement with the City and transports solid waste to a landfill site on Vasco Road. PG&E provides gas and electrical service to Hacienda. Significance Criteria The impact questions above constitute the significance criteria for this environmental topic. Discussion of Checklist Items Less- than - Significant Impacts. Capacity of the Dublin San -Ramon Sanitary District ( DSRSD) treatment plant is 17 million gallons per day (mgd), of which Pleasanton's allotted share is 8.5 mgd. Pleasanton is currently using about 6 mgd of its allocation. Therefore, adequate capacity exists to serve the development accommodated by the proposed zone change. DSRSD has a maximum treatment plant ultimate design capacity of 20. mgd, although it has not begun expansion planning for its current sewage treatment plant. The three development sites allowed under the Hacienda TOD Standards and Guidelines would generate an estimated total average dry weather wastewater flow of 270,000 gallons per day. In peak dry weather periods this additional wastewater flow is estimated to increase to an additional 450,000 gallons compared to what was planned in City's Wastewater System Master Plan dated August 2007. There is sufficient pipeline capacity in local sewer lines that are immediate and downstream of these three sites for average and peak dry weather flow discharges. However, this additional sewer flow impact would exacerbate the capacity issues in the existing sewer trunk main (East Amador Trunk Sewer, EATS) where this additional discharge would flow into. Although based on the City's engineering analysis it is estimat: d that there is sufficient capacity remaining in the EATS pipeline for one of the vacant sites to be developed with no additional improvements in place, development of the second and third sites would require repair to an existing "currently out of service" sewer trunk main, and construction of a new pump station. The cost of these improvements is estimated at $3.5 million, and would be financed utilizing the City's sewer Development Fund, and Replacement Improvement Fund. The split between the two sewer funds will be based on a pro rata share between the existing City sewer customers and future development in accordance with a benefit assessment analysis. These improvement projects are currently included in the City's Capital Improvement Program to be constructed in fiscal year 2013/2016 and are planned to be moved forward to 2011/2012 (with City Council approval) to accommodate the additional sewer discharge from the new housing units.
