Corps’ Draft “White Paper”

Corps’ Draft “White Paper”

Why Was the Roundtable Established?

Recognition of high risk to public safety due to levee erosion, encroachments, seepage, channel capacity & vegetation management

Draft Corps “White Paper” on the “Treatment of Vegetation Within Local Flood Damage Reduction Systems”

Issued by the US Army Corps of Engineers in April 2007 Triggered by devastation of New Orleans by Hurricane Katrina in

2005 Enforcement of existing levee maintenance standard

National standard poses major challenges for the Central Valley Flood Management System

NEEDED COLLABORATIVE SOLUTION 4

California Levees Roundtable Goals

Establish a dialog among the leadership of levee maintaining agencies and resources agencies regarding maintenance on California’s Central Valley levees.

Develop collaborative relationships among the stakeholders to work toward policy solutions regarding maintenance of California’s Central Valley levees.

Achieve consensus on broad policy guidance on California levee vegetation standards that protect public safety and critical habitat.

Gain agreement on a process and next steps toward establishing and implementing sustainable California levee maintenance standards, while conserving or enhancing existing habitat for fish and wildlife species.

5

Roundtable Agreements

Public safety is the top priority

Vegetation management is only one of many issues that threaten levee integrity

Draft a phased system-wide plan to address highest risks to levee stability and public safety first (the Framework)

Includes short- and long-term elements

Levee maintaining agencies should defer any substantial vegetation removal along levees while the plan is being developed

Any vegetation removal to comply with applicable State and Federal laws

There is an urgent need to reduce risk throughout the Central Valley by applying a system-wide remedy to levee threats

6

The Framework

Short-term Framework for flood system improvements that are already underway or will be initiated before a comprehensive plan (CVFPP) is ready in 2012

Geographic scope of Framework same as CVFPP

Activities outlined in the Framework are focused on addressing five threats to improve public safety

Channel Capacity Seepage Erosion Encroachments Vegetation

No single threat given priority in the short-term7

Interim Levee Vegetation Inspection Criteria

Criteria apply on: Entire landside slope plus a 10-feet wide easement

beyond the landside toe. Top 20 feet (slope length) of waterside levee slope.

Trees trimmed to five feet above the ground (12 foot clearance above the crown road) and thinned enough for visibility and access

Brush, weeds, or other such vegetation over 12 inches high blocking visibility should be trimmed, thinned, mowed, burned, dragged, or otherwise removed in an allowed manner.

Important Milestones of Framework

LMAs to maintain levee vegetation according to the DWR’s Interim Levee Inspection Criteria for Vegetation

Levees in the Central Valley to be in compliance with the interim vegetation requirements by November 1, 2010

Report by LMAs of compliance with interim vegetation standards by November 1, 2009

21

Much Has Already Been Accomplished

Significant progress made in 2008! Implementation of Interim Inspection Criteria System wide investigations proceeding Portions of the system meet Corps standards

Agreement to measure progress toward remaining Framework goals annually

Corps and DWR

Flood System to remain “active” in PL 84-99 Eligibility reviewed annually Eligibility reconsidered in 2012

Corps HQ letter, January 9, 2009 Sets requirements for extension of PL84-99 eligibility

22

Long-term Approach

Conserve and enhance riparian habitat on the waterside of levees

Aggressively pursue compliance with Corps levee standards including vegetation using:

Improved maintenance inspections

Phased vegetation management practices

Regional variances

Engineered alternatives

23

Long-Term Approach (continued)

Fully integrate the short-term activities with California FloodSAFE initiative

System-wide Central Valley Flood Protection Plan (CVFPP)

Development underway with implementation scheduled to begin in 2012

Develop Multi Species and Floodplain Conservation Strategy

Conduct research on effects of vegetation and vegetation management on levee integrity/performance

24

Continued Collaboration and Next Steps

Roundtable participants are committed to broad based stakeholder collaboration

Many specifics of the Framework will be resolved during the next four years as implementation progresses

Levee integrity concerns will be addressed collaboratively by federal, State, and local agencies during the development and implementation of the Central Valley Flood Protection Plan and the California FloodSAFE initiative

25

Outstanding Issues Ahead

Define standardized maintenance processes and responsibilities of LMAs

Address authorized and unauthorized encroachments

Processes for identification and enforcement

Develop stable funding mechanisms at federal, state and local levels

Assist LMAs achieve stable and sustainable funding

Work with FEMA on levee certification issues

Complete research initiatives26

Outstanding Issues Ahead (continued)

Identify applicable environmental law requirements relating to short and long-term actions

Develop CA vision addressing environmental protection and public safety concurrently

Define opportunities for LMAs to cost effectively mitigate impacts of levee maintenance

Develop programmatic approaches for environmental compliance

Define ESA consultation or permitting alternatives

Staff Recommendation

Staff recommends that the Board approve “California’s Central Valley Flood System Improvement Framework” developed by the California Levees Roundtable.

Staff recommends that the Board direct its Executive Officer in collaboration with the Department of Water Resources to submit the Framework Document on behalf of the State, to the U.S. Army Corps of Engineers demonstrating, the many ongoing and planned system-wide improvements and seek temporary extension of PL 84-99 eligibility based on the U.S Army Corps of Engineer’s Director of Civil Works January 9, 2009 memorandum.
