In a suit challenging the city's approval of a project to build a home on a lot in the Berkeley hills, challenging the project under the California Environmental Quality Act (CEQA), Pub. Resources Code section 21000 et seq., on remand from the Supreme Court, the trial court's order denying appellants' petition for a writ of mandate is affirmed where sufficient evidence supports the city's conclusion that the project is categorically exempt from further CEQA review.
