Architectural and Site Plan Review. An applicant for a use permit shall submit architectural drawings, the elevations of all buildings and a site plan which indicates how the standards listed in this section will be met. Development plans are also subject to the City of Susanville Design Guidelines, adopted July 17, 2002, as may be amended. This submittal shall be made on a form prescribed by the community development director and shall include such additional plans, drawings and information as the planning commission from time to time may require by resolution. Such drawings and site plans shall be considered by the planning commission at a public meeting. The planning commission must find that the architectural and general appearance of such buildings or structures and grounds are in keeping with the character of the neighborhood and will not be detrimental to the orderly and harmonious development of the city. The planning commission may approve, conditionally approve or disapprove the plans. Architectural and site plan review will be a part of the use permit process and the director's approval shall occur as set forth by the terms and conditions of the use permit.
