F..~ In response to an inquiry by Commissioner Blank regarding whether Pleasanton would experience a water shortage if the tank activation did not go as planned, Mr. Cusenza said no. Commissioner Blank inquired whether that contradicted staff s earlier assessments; Mr. Cusenza replied that was not the case. He noted that the possibility of a Pleasanton water shortage was unlikely because that was a sepazate part of the water supply formula and criteria used by staff. The City receives 80 percent of its water from Zone 7, and the City owns ground water to supply the other 20 percent. The tank's supply was independent of the pumping and storage in each zone. This facility would get the water from Zone 7 into the reservoirs to meet emergency, fire, and daily demands. In response to an inquiry by Commissioner Fox regarding whether an evacuation map would be required in the event of a breach during an earthquake, Mr. Cusenza replied that all of the tanks were designed for significant seismic loading in the San Francisco Bay Area. A catastrophic failure has not been experienced; he noted that the buried concrete water tanks would crack and leak, and the steel tanks would bulge at the bottom without rupturing. He displayed the site plan on the overhead screen and described the grading of the site. Mr. Cusenza noted that this project was budgeted in 2001, and the tank portion of the project was sited on the best location available. Staff was concerned that the construction season would be missed if the project is not sent out to bid soon. He added that it would take approximately nine to twelve months to construct. ~'-'' In response to an inquiry by Commissioner Blank regarding whether approval of the tank did not lock the Commission into a specific configuration regazding the placement of the road and the lots, Ms. Decker replied that the original plan was to have the approval of the road along with the tank. She noted that the construction of the road provided some assurance regazding the agreement between Mr. Reznick and the City to move forward with the construction of the tank itself. At the workshop, the Planning Commission felt somewhat reticent in terms of moving forwazd without knowing how the grading of the road and the pads would be affected. The City did have some concerns about being locked into a road alignment with the pads placed. After further investigation and with the City engineers having spoken with the developers' engineers, two designs created for the site had been joined into what staff believed was the best alternative regazding the road alignment and grading. With respect to the issue related to the grading of the pads, Ms. Decker noted that the two affected neighbors, Mr. Brozosky and Ms. Roberts, had made their concerns known regazding the amount of fill. The current design showed the pads being level with the road at some particulaz point, which would allow a level driveway to the front of the house, and it would be an opportunity to place some of the off-haul on the site. Staff would be able to bring this information back to the Commission if a comfort level cannot be reached with respect to the grading. In response to an inquiry by Commissioner Blank regazding whether the Commission was being locked into a road design, Mr. Jost replied that there was still an ongoing PLANNING COMMISSION MINUTES, May 10, 2006 Page 8 of 19
