"San Diego County, already straining with traffic and other growing pains, is projected to get 1 million additional residents by 2020. The county's patchwork of local governments may be incapable -- because of competing interests and limited powers -- of fixing the regional problems that population surges inevitably bring." Historically, "Regionalism" has not been a popular concept in San Diego, but officials are hoping that some progress can be made to improve relations.
