I have been asked this of late and the short answer is "I'm not sure."
The meeting on the 15th allowed many to present their views and the neighbors continue to discuss this situation - assessing the legal and political ways similar issues have been dealt with in other jurisdictions.
A meeting on the issue of trees and levees is scheduled in California and some from both the neighborhood and the drainage district are attending. I assume we will get some feedback at the meeting on August 30th.
I will post info as it is received....
