It is the purpose of this chapter to regulate and control the division of land within the City and to supplement the provisions of the State Subdivision Map Act concerning the design, improvement and survey data of subdivisions, the form and content of all maps provided for by the State Subdivision Map Act and the procedure to be followed in securing the official approval of the City of Sebastopol regarding such maps. The intent of this chapter is to encourage orderly development and to ensure that appropriate public improvements are provided. To accomplish these purposes, the regulations outlined in this chapter are determined to be those reasonably necessary for the preservation of the public health, safety, and general welfare, to promote orderly growth, development, open space, conservation, protection and proper use of land, and to ensure provision for adequate traffic circulation, utilities and services and to promote and implement the General Plan.

C. The City may not approve a subdivision of land unless the subdivider establishes that the subdivision and construction of improvements will be appropriately timed and phased such that the development will be supported by adequate facilities and services, and such that appropriate measures can be taken to mitigate adverse environmental impacts. Adequacy of facilities and services shall be determined in accord with (1) the planned long-term build-out of the community as provided in capital improvement programs in which facilities are actually available or funded, and (2) the General Plan element in effect at the time of considering the application.
