Project Description Addendum to the City of Pleasanton Downtown Specific Plan Final Environmental Impact Report 13 Green Building Features The proposed project would include several sustainability features to help reduce greenhouse gas (GHG) emissions and meet City-wide sustainability goals. The project would comply with the 2022 California Green Building Standards Code (CALGreen) as well as PMC Chapter 17.50, Green Building. The project would be Leadership in Energy and Environmental Design (LEED) silver certified. Pursuant to PMC Section 20.26.370, Section 5.106.13 added—All-electric buildings, the proposed residences would be all-electric and would have no natural gas or propane plumbing installed. Electricity would be the sole source of energy for space and water heating. The residential portion of the proposed project would include a photovoltaic solar array on the roof of all houses pursuant to the California Energy Code. The proposed commercial buildings would use natural gas. Heating, ventilating, and air conditioning system (HVAC) systems to be installed as part of the project would incorporate the lowest global warming potential refrigerants. The project would provide adequate recycling, compost, and landfill containers to meet Senate Bill 1383 and comply with PMC Chapter 9.20, Garbage. The project would incorporate water-efficiency measures, including efficient water fixtures and climate adapted plantings. Construction Construction would commence towards the end of 2024 or early 2025, which is within the DSP’s planning horizon of 2040. Overall construction of the Barone’s project would take approximately 26 months, including demolition, site preparation, grading, building construction, paving, and architectural coating. Construction would occur on all days, except for Sundays and holidays from approximately 8 a.m. to 8 p.m. (within PMC regulations). All structures on the project site would be demolished, except for the single-family residence, resulting in a total of 1,877 square feet of demolished buildings. Grading would likely result in approximately 4,200 cubic yards of material being exported from the site, and material would be hauled to the Pleasanton Landfill at 3110 Busch Road. All construction equipment would be staged onsite and several pieces of equipment would include the use of only Tier 3 and Tier 4 engines, as detailed in Section 5.2, Air Quality. The project would comply with PMC Chapter 9.21, Construction and Demolition Debris, and achieve recycling or reuse of at least 90 percent of Portland cement concrete and asphalt concrete and at least 75 percent of the remaining construction and demolition debris. Required Approvals Prior to development the following discretionary approvals from the City would be required:  PUD Mixed-Use application to rezone the two parcels from C-C to PUD-MU  Building Permit for addition and ADU on existing residential property Furthermore, while not anticipated, if the project were to result in alterations to the riparian corridor of Arroyo del Valle or discharge of stormwater into Arroyo del Valle, Waste Discharge Requirements from the San Francisco Bay Regional Water Quality Control Board (SFBRWQCB) and a Lake or Streambed Alteration (LSA) Agreement from the California Department of Fish and Wildlife (CDFW) may be required. It is not expected that the project would result in the discharge of dredged or fill materials into Arroyo del Valle; accordingly, a Clean Water Act Section 404 permit from the U.S. Army Corps of Engineers is not anticipated to be required.
