The DC trip is presumably to get money from the federal government. Given Eisenberg has been very critical of these projects, her attendance would likely significantly reduce the probability of getting the funding and also reduce the funding amount.

This should surprise no one. Ms Eisenberg's behavior was evident to anyone who paid even the slightest attention to her history before she ran for this office.

Combined with her behavior on the creek JPA, she is causing a lot of damage. Is it time for a recall?

I’m not in the least surprised. RE is often combative and can handle disagreements with very little tact. I would not vote or endorse her for anything.

As @ralphc said, Eisenberg's actions on the water board should have surprised nobody who watched her (fortunately) failed bid in 2020 for Palo Alto City Council. From her linked-in page:
"I ran for Palo Alto City Council to address the overwhelming corruption in our city."

On June 19, 2020 Web Link Eisenberg's position included:

"Palo Alto voters should know in my statement that I am in full support of #BLM and am joining my community in calls to #DefundThePolice. Anything less than this does not meet the moment, and fails to deliver justice for the thousands of Black Americans whose lives are endangered by the police force every day."

"The City Council needs to put forth a plan to defund, disarm, and disband the police department."

Voters need to remember her plan for destroying city government and her destructive behavior on the Water Board the next time Eisenberg runs for ANY elected position in the Bay Area.

How about the District spend some of the $10k she's demanding (and the District isn't paying) on an anger management program? Director Eisenberg's approach to everything obstructs the critical business of managing water resources. And it's tiresome.

I didn't vote for Ms. Eisenberg. As a member of the public who occasionally attends public meetings, I observed her close her mind to alternative points of view and verbally abuse members of Planning & Transportation Commission, City Council...and others who sometimes disagreed with her. This is a pattern of behavior.

Fellow citizens, engage more with your government. It's not enough to vote. Occasionally attend public meetings to understand WHO you are voting for.

There were only two people running for water board, and this was the incumbent.

"An independent investigation determined Gary Kremen, a Valley Water board member up for reelection in November, violated several district policies when he bullied, verbally assaulted and threatened district workers."

“Given his conduct, Director Kremen should hold a press conference, apologize and ask all of his supporters to vote for his opponent because clearly he’s unfit to be a director,” board member Linda LeZotte told San José Spotlight.
