San Ramon Municipal Code Art. 1 Policy

To conserve the public interest and to assure economies and public safety and welfare, it is imperative that necessary rights-of-way for streets within the city be protected against encroachment by permanent physical improvements, the existence of which would make unnecessarily difficult or make impractical the retention or creation of thoroughfares, adequate in alignment, dimensions and vision clearance to serve the public needs, safety and welfare. To deal effectively with the practical problems, it is necessary to establish certain minimum building line setbacks on a city-wide basis. (Ord. 230 § 2 (Exh. A) (part), 1992)
