Chapter 18.15 — R-1 ZONE RESIDENTIAL SINGLEFAMILY

It is hereby found and declared that the City of Norco lies in a natural setting of rural, scenic and historical beauty; that this rural environment generates a strong characteristic for development of Norco as a new equestrian focal point in southern California; that this unique rural environment and historically significant location contributes a material economic advantage to the citizens, businesses, and industries within the City and particularly to the property owners who reside therein; and that development in an orderly manner with compatible uses and appearances of structures within and between zones and with the natural rural environment is necessary to maintain such historic and economic advantage, to stabilize, protect, and maintain property values, and to encourage permanence of desirable residential areas.

This zone is intended to provide for the development of single-family residential areas and to designate appropriately located areas for family living at designated population densities. The provisions of this zone are intended to ensure that the residential character of such areas will be stabilized and maintained. They are further intended to provide a basis for planning of related

amenities such as parks, schools, public utilities, streets and highways, and other community facilities. (Ord. 1019 Sec. 1, 2017)

This zone shall be separated into sub-zones to delineate required minimum lot size. The sub-zone shall be identified by a numerical suffix after the "R-1" designation on the zoning map; and each and every area zoned R-1 in the City of Norco shall have a numerical suffix appended thereto. Said numerical suffixes shall designate the required minimum lot size in thousands of feet. For example:

R-1-10 = 10,000 square feet minimum lot size;

R-1-15 = 15,000 square feet minimum lot size;

R-1-20 = 20,000 square feet minimum lot size; etc.
