Following are our comments for your consideration: 1. Livermore Valley Groundwater Basin-Groundwater Quality. The project area is situated over an upland portion of the Livermore Valley Groundwater Basin; as such,the underlying groundwater is subject to the management provisions of the basin's Alternative Groundwater Sustainability Plan (GSP), which was prepared by Zone 7 Water Agency and approved by the State Department of Water Resources in 2019.As the designated Groundwater Sustainability Agency (GSA), Zone 7 strives to maintain sufficient groundwater supplies and good groundwater quality within the groundwater basin. To support these goals, the project needs to be consistent with the Alternative GSP and Zone 7's Sustainable Groundwater Management Ordinance, as well as the State's Water Recycling Policy (and associated orders), and the County's Water Wells Ordinance. Links to many of these documents can be found on Zone 7's website at https://www.zone7water.com/. 2. Groundwater Wells. Section 5.9 of the IS/MND states, "The project would not use groundwater to provide water for this project;" however, our records indicate there is one water well (3S/lE 28L 2) located in the project area. If any other well is discovered in the project area, it should be reported to Zone 7 immediately. County Ordinance Code (Chap 6.88), which was also adopted by reference by City of Pleasanton,prohibits the existence of"abandoned wells"and requires any such well to be destroyed under a permit issued by Zone 7. An "abandoned" well is defined as, "Any well that is not "active" nor been used at least once in preceding twelve(12)months for its intended use." The approximate location of the well is shown on the attached map. The application form necessary for the well destruction permit and associated fee schedule can be downloaded from the Zone 7 website at http://www.zone7water.com/permits-a-fees/64-well-drilling-and-destruction-perm its. 3. Septic Tanks. Section 5.17 of the IS/MND states, "The project would not discharge any waste, other than domestic sewage, and all sewage would be discharged into the City's sanitary sewer system for ultimate treatment."Because the existing land use is rural residential in nature,the existing dwelling unit may have been served at some point by an onsite wastewater treatment system i.e., septic tank and leachfield. If one exists on the site, it should be excavated and completely removed prior to grading to Page 1 the other for survival or the area's natural beauty. 20 ive by having the additional two parcels.
