E1: Vegetation Control and Sediment Removal for Flood Protection

This project supports the District’s ongoing vegetation control and sediment removal activities that reduce flood risk by maintaining design conveyance capacity of flood protection projects. These activities also provide access for maintenance personnel and equipment. The project includes: controlling in-stream vegetation growth, removing sediment at appropriate intervals, removing hazardous trees, and performing weed abatement and pruning to provide access and establish firebreaks. Before carrying out in-stream maintenance, District personnel perform biological pre-construction surveys to minimize environmental impacts. Allocations for Project E1 also helps fund future maintenance of flood protection projects completed under the Safe, Clean Water program.

This project is comprised of 4 sub-projects that support the District's ongoing vegetation control and sediment removal activities. Reference Appendix B in the 5-Year Implementation Plan for project descriptions. These sub-projects are:

E1.1 Vegetation Control for Capacity
E1.2 Sediment Removal for Capacity
E1.3 Maintenance of Newly Improved Creeks
E1.4 Vegetation Management for Access


Benefits

  • Ensures that existing flood protection projects continue to provide maximum flood protection
  • Provides safe access for maintenance of creek channels
  • Reduces fire risk along creeks and maintains compliance with fire codes
  • Improves water quality

Project Status

(As of January 2017)

  • Completed 3,706 acres of maintenance access work in all five watersheds during FY16. The total acreage year to date for FY17 is 604 acres relative to an annual target of 2,720 acres. The Q2 target for this priority is 1,360 acres, however, most of our acreage is completed in Q3 & Q4.
  • Of this total acreage, 15% of the completed work was funded by Safe, Clean Water.
  • During the first three years of the program, the total accomplishment for the program is 1,410 acres, compared to a three year target of 1,224 acres. To date, the program is on target for year three.

Key Performance Indicator

  1. Maintain 90% of improved channels at design capacity
  2. Provide vegetation management for 6,120 acres along levee and maintenance roads
