San Diego Municipal Code Div. 3 Agricultural Base Zones

(Added 12-9-1997 by O-18451 N.S.; effective 1-1-2000.)

The purpose of the agricultural zones is to provide for areas that are rural in character or areas where agricultural uses are currently desirable. The agricultural zones are intended to accommodate a wide range of agriculture and agriculture-related uses as well as single dwelling units. (Added 12-9-1997 by O-18451 N.S.; effective 1-1-2000.)

(a) The purpose of the AG zones is to accommodate all types of agricultural uses and some minor agricultural sales on a long-term basis. Nonagricultural uses are limited in the AG zones in order to strengthen the presence and retention of traditional agricultural uses.

(b) The AG zones are differentiated based on the minimum lot size as follows:

• AG-1-1 requires minimum 10-acre lots
• AG-1-2 requires minimum 5-acre lots
(Added 12-9-1997 by O-18451 N.S.; effective 1-1-2000.)

(a) The purpose of the AR zones is to accommodate a wide range of agricultural uses while also permitting the development of single dwelling unit homes at a very low density. The agricultural uses are limited to those of low intensity to minimize the potential conflicts with residential uses. This zone is applied to lands that are in agricultural use or that are undeveloped and not appropriate for more intense zoning. Residential development opportunities are permitted with a Planned Development Permit at various densities that will preserve land for open space or future development at urban intensities when and where appropriate.
