The following sections of the Contra Costa County Ordinance Code, adopted by reference in Section 1 of this ordinance are amended to read as follows:

a) 92-2.002 Title. This Title may be known as the "Subdivision Ordinance" of the Town of Moraga.

b) 92-2.006 Scope. Under Division 2 of Title 7 of the Government Code, State of California (the Subdivision Map Act) and in addition to any other regulation provided by law, this Title applies to all subdivisions hereafter made entirely or partially within the Town.

c) 92-4.006 Arterial Street. "Arterial Street" is a street or road passing through or adjacent to a subdivision which carries the major flow of traffic. The term includes an arterial street shown on the General Plan as now or hereafter amended.

d) 92-4.034 Frontage Road. "Frontage Road" is a street or road adjacent to an arterial or thoroughfare which provides access to abutting properties and protection from the through traffic on the more heavily traveled street.

e) 92-4.090 Subdivision. "Subdivision" means the division of any improved or unimproved land, shown on the latest equalized County assessment roll as the unit or as contiguous units, for the purpose of sale, lease or financing, whether immediate or future, except for leases of agricultural land for agricultural purposes for the cultivation of food or fiber or the grazing or pasturing of livestock. Property shall be considered as contiguous units, even if it is separated by roads, streets, utility easement or railroad rights-of-way. "Subdivision" includes a stock cooperative, a condominium project as defined in Section 1350 of the Civil Code or a community apartment project, as defined in Section 11004 of the Business & Professions Code. Any conveyance of land to a governmental agency, public entity or public utility shall not be considered a division of land for purposes of computing the number of lots. "Subdivision" shall not include a division resulting from a conveyance of land or interest therein to an abutting property owner, not involving the creation of a new building lot or site, and both parcels or lots will conform in all other respects to this division and the County zoning ordinances after such division, provided it is approved by resolution of the Zoning Administrator.

f) 92-6.006 Modification of Requirements. The standards and requirements of these regulations may be modified by the Planning Commission for a Planned Development application. In varying the development standards provided in Section 92-6.002, the authority to do so may only be used so as to be consistent with the intent of the General Plan to permit remaining land holdings to be developed primarily as conventional detached single family subdivision.

g) 92-8.002 Conformance to Code. Each subdivision subject to this Title shall conform to the codes, ordinances and regulations of the Town.
