Document Title
Centennial Specific Plan Project
Document Type
NOP - Notice of Preparation of a Draft EIR
Document Description
The current Project consists of the applicant’s proposed minor adjustments to the 2019 previously approved Project, a master planned community for 19,333 residential units, which include (1) allowing utility-scale battery storage and microgrids to improve the resilience of the Specific Plan’s onsite renewable energy electricity program in support of the Net Zero GHG program, and (2) modifying the Specific Plan’s internal roadway design standards to improve evacuation capacity for future project residents. Based on the Climate Resolve settlement, the SEIR will supplement the Centennial EIR and will focus the supplemental analysis on GHG and Wildfire. The Project development area and substance of the Project as a master planned community in this location has not changed when compared to the 2019 approved Project. The SEIR will analyze the impacts of the Project on all County-adopted thresholds of significance, as well as the Project’s consistency with the adopted Countywide General Plan 2035 and the 2015 Antelope Valley Area Plan (“AVAP”).
