In Plaggmier v. City of San Jose (1980) 101 Cal. App. 3d 842, the city chose the direct mailing method to provide public notice of the proposed negative declaration to owners of the contiguous properties, but failed to actually mail the notice to the property owner who sought to challenge the project. ( Id. at pp. 847-848, 849-850.) Under those circumstances, the court invalidated the subsequent approval of a shopping center based upon the lack of actual notice. ( Id. at p. 857.)
