We’ve been wondering how the county would spend $80 million per year on the sewage-plagued Tijuana River under a proposed half-cent sales tax measure proposed by the San Diego County Supervisors. On Friday, Supervisor Paloma Aguirre (the issue’s main champion and former mayor of sewage-blighted Imperial Beach) put out her proposed plan. Main message? Convert a large chunk of that money into a bond (a big loan governments often take out to finance expensive projects) and have the county build a system that treats the entire Tijuana River. It’s also known as the “river diversion” project and Aguirre’s been pushing for it since she was mayor. That basically involves running the river on the United States side through a new treatment plant (called advanced primary treatment) so that raw sewage doesn’t make its way to the Pacific Ocean (and Imperial Beach).
