City of Pleasanton 2023-2031 (6th Cycle) Housing Element Update Introduction Draft Program EIR 1-2 FirstCarbon Solutions https://adecinnovations.sharepoint.com/sites/PublicationsSite/Shared Documents/Publications/Client (PN-JN)/2148/21480022/EIR/3 - Draft/21480022 Sec01-00 Introduction.docx The City is planning for an amount of allowable development under the Housing Element Update to meet the City’s RHNA obligation. Each site has been assigned a density range, denoting the minimum and maximum density at which new housing may be built. Housing Element law requires the Housing Element to demonstrate the “realistic capacity” for each site in determining whether adequate sites are available, and, for the purposes of the Housing Element Update’s sites inventory, the City has generally taken the approach that sites will develop at a density somewhat less than the maximum allowable in the range. However, recognizing that the zoning will allow for, and some sites could conceivably develop at, the maximum density allowed, to present a conservative analysis of potential environmental impacts, this Draft Program EIR assumes the maximum potential number of residential units on each site, resulting in the analysis of a total of 7,388 units. It should be noted that this provides a conservative analysis with respect to environmental impacts while recognizing that it is unlikely that all the sites would develop at maximum density and actual development capacity would account for factors like site constraints, market fluctuations, and other variables. Based on realistic development projections, the Housing Element Update anticipates that 93 accessory dwelling units (ADUs) would also be constructed.2 Additionally, the Housing Element Update assumes an increased density at the Dublin-Pleasanton Bay Area Rapid Transit (BART) station property, and this Draft Program EIR incorporates analysis of an incremental increase in allowable residential units (306 units). This Draft Program EIR assumes a maximum of 7,787 dwelling units and a maximum of 18,027 new residents.3,4,5,6 The final list of approved sites to be adopted by the City Council would be accompanied by the General Plan and Specific Plan Amendments and rezoning actions to accommodate residential housing development, which are analyzed in this Draft Program EIR. Although the general locations and types of development can be anticipated based on the guidance in the Housing Element Update, until the City receives a development application for subsequent development consistent with the Housing Element Update, the exact locations, types of development, and potential site-specific impacts to the environment are too speculative to be determined. As appropriate, future construction and development plans would be subject to project- level CEQA analysis and potentially additional feasible mitigation, if necessary. 2 The ADU estimate is based on the average past 5 years of actual production within Pleasanton, which is consistent with California Department of Housing and Community Development (HCD) guidance. Given that this Draft Program EIR considers the maximum number of units on the potential sites for rezoning, should any of the Housing Element Update policies facilitate the production of ADUs, any additional units over the 93 units would be accounted for within this evaluation because it is unlikely that all of the sites will develop at maximum density. 3 United States Census Bureau. 2019.

Accessed March 8, 2022. 6 For Sites 15 and 21b, the low density, 2.99, persons per household factor was utilized because that results in a higher population estimate, which presents a conservative population estimate. For ADUs, the high density, 2.2, persons per household factor was utilized because ADUs are accessory units that, by their nature, house less people. Therefore, given the density classes being evaluated in this Draft Programmatic EIR, the high density persons per household factor is the most reasonable to utilize for ADUs.
