In Branzel v. City of Concord (1966) 247 Cal. App. 2d 68 55 Cal. Rptr. 167, a field owned by the city and maintained for use as a flying model airplane field was in close proximity to privately owned high power electrical lines. The court held the city could be liable for a dangerous condition on its property even though the danger was created only because of the presence of privately owned property. (Id. at pp. 73-75.) These case establish that a public entity is liable for a dangerous condition on property it owns even though the danger would not exist but for the presence of privately owned equipment on or adjacent to the public property.
