The applicant for a building permit in any zone shall dedicate any half streets that have not been dedicated, or the applicant shall dedicate additional right of way as may be shown on the general plan or on any approved precise street plan or setback ordinance which sets forth rights of way in excess of those now in existence. Any street not shown on any official plan shall have a right of way of not less than sixty feet (60'), and the applicant for a building permit shall dedicate additional right of way to provide for a thirty foot (30') half street. All required setbacks shall be measured from the proposed right of way line shown on the general plan, precise street plan, or setback ordinance. (Ord. 1000 § 33.00(B), 1955)
