A group of local officials from around the county introduced a resolution Tuesday calling on the federal government to take action to stop cross-border sewage flows in the Tijuana River Valley.

The group of officials — including San Diego Mayor Kevin Faulconer, Imperial Beach Mayor Serge Dedina, Port of San Diego Commissioner Dan Malcolm and county Supervisor Greg Cox — held a news conference in Imperial Beach to introduce a list of recommended actions, which will be voted on by multiple city councils and boards in the coming weeks.
