Broader Project Site Acreage

Feb 2019

Broader Daggett Solar Power Facility site comprises approximately 3,393 acres across 51 assessor parcels; hydrology appendix describes approximately 3,141 acres across six CUP sites and three phases

Acreage figures apply to broader Daggett Solar Power Facility containing Daggett 2, not Daggett 2 alone. Public records do not assign separate acreage to exact EIA 64851 phase.

County Land Use Approvals

Oct 1, 2019

San Bernardino County approval: P201700679 for six Conditional Use Permits; P201900243 / Tentative Parcel Map 20083

County staff report documents approval of six CUPs for 650 MW photovoltaic and up to 450 MW storage under P201700679, plus TPM 20083 under P201900243. These are broader-facility approvals encompassing phased project rather than separately numbered Daggett 2 permit.

Groundwater Supply And Impact

2019

Water Supply Assessment found sufficient groundwater for normal, single-dry, and multiple-dry years over 20-year projection. EIR classified potential groundwater-level impacts east of Calico-Newberry Fault as significant and unavoidable

EIR distinguishes water-supply adequacy from groundwater-level impact: supply deemed adequate under modeled conditions, but no feasible mitigation available for certain future groundwater-level effects and cumulative hydrology impacts.
