SAN DIEGO (CNS) - The San Diego County Board of Supervisors agreed Wednesday to take one more month to consider a major update to the county's decades-old land-use policy.

The board has been receiving public comment since October on a comprehensive update to its general plan, which has been in effect since 1978. The process to modernize the zoning guidelines began 12 years ago.

The update envisions shifting development westward, closer to existing infrastructure, sparking intense opposition from hundreds of residents to various details within the plan that affect them. However, few have objected to the plan in its entirety.

A majority of the opponents asked for reconsideration of population density guidelines, but staff in the county Department of Planning and Land Use expressed concern that changes could require revisions in the environmental impact report.

Department Director Eric Gibson said that scenario could result in a delay of anywhere from three months to four years in finalizing the general plan.

Board Chairman Bill Horn said the continuing saga of the update was becoming "the longest-running TV show," and that it was starting to feel "more like Days of Our Lives."

Land-use staffers considered 231 requests by the public to alter the proposed plan, and presented an analysis of 27 of them to the supervisors. They said density levels were determined by fire risk, impacts to groundwater and legal concerns.

Horn said the supervisors would need time to review the new information, and would likely have follow-up questions.

Supervisor Dianne Jacob agreed.

"No doubt we'll have a lot more questions and discussions in the future," she said.

The next meeting on the general plan update is set for March 16.
