In a published opinion filed February 6, 2023, the Fourth District Court of Appeal (Div. 3) affirmed a judgment setting aside an addendum to a 2010 program EIR (PEIR) and accompanying approvals for a 275,000-square foot office complex on a 4.95-acre parcel (the “Gemdale project” or “project”) within the 2,800-acre Irvine Business Complex (IBC). IBC Business Owners for Sensible Development v. City of Irvine (Gemdale 2400 Barranca Holdings, LLC, Real Party in Interest) (2023) 88 Cal.App.5th 100. The Court held that the City’s approval of the Addendum was improper because substantial evidence did not support the conclusion that the project’s GHG emissions were within the scope of the PEIR and would have less than significant impacts; further, the project was unusually large and dense due to its utilization of transfers of development rights (TDRs) of over 220,000 square feet – by far the largest ever approved in the IBC’s history – and thus could not qualify for the Class 32 infill exemption due to the unusual circumstances exception.
