90507.00 - Purpose and application.

The purpose of the A-1 designation is to designate areas and allow uses that are suitable for larger residential living environments. The uses are generally limited to those typical of and compatible with quiet residential neighborhoods. The minimum lot size shall be one-half acre (net), unless required to be larger by other regulatory requirements, such as health and safety standards. The minimum lot size in the A-1 zone may be reduced if public infrastructure including sewer and potable water are available from either a district or a city. The A-1 designation is only allowed within urban designated areas as reflected on the land use diagram of the county general plan.

COMMENT: The acreage here needs to be "net" vs. "gross" due to the fact that the absolute minimum amount of land needed for sewage disposal is twenty thousand (20,000) square feet of usable land, and the county already has numerous locations where this creates problems.
