1. San Francisco LTMS : Accomplisments And New Challenges SFBJV, March 29, 2011

2. Five Key Challenges Facing the Estuary: – Decline of biological resources (especially wetlands and related habitats) – Increased pollution – Freshwater diversions and altered flow regime – Intensified land use and population – Dredging and waterway modification The San Francisco Bay LTMS – Implementing arm of the CCMP for Dredging and Waterway Modification Five Key Challenges Facing the Estuary: – Decline of biological resources (especially wetlands and related habitats) – Increased pollution – Freshwater diversions and altered flow regime – Intensified land use and population – Dredging and waterway modification The San Francisco Bay LTMS – Implementing arm of the CCMP for Dredging and Waterway Modification Origin of the LTMS The San Francisco Estuary Project’s CCMP

3. Maintain…those channels necessary for navigation…and eliminate unnecessary dredging Conduct dredged material disposal in the most environmentally sound manner Maximize use of dredged material as a resource Establish a cooperative permitting framework Maintain…those channels necessary for navigation…and eliminate unnecessary dredging Conduct dredged material disposal in the most environmentally sound manner Maximize use of dredged material as a resource Establish a cooperative permitting framework The LTMS Goals

4. Percent of all Disposal Minimize In-Bay Disposal Maximize Beneficial Reuse Minimize In-Bay Disposal Maximize Beneficial Reuse Plan The LTMS Plan

5. Long-term Goal Initial: LTMS annual limit less than 1/2 previous limits 1/1/10: Annual limit reduced by another 1,135,500 cy Step 2: 12-Year Transition Period Systematically Reduces In-Bay Disposal In-Bay Disposal Step 2: 12-Year Transition Period Systematically Reduces In-Bay Disposal In-Bay Disposal How To Get There

6. In-Bay Disposal In-Bay Disposal – Significantly reduced: disposal limits have been met every year – Mostly done successfully within Environmental Work Windows Ocean Disposal Ocean Disposal – Successful low-impact alternative – Over 15 million cy diverted from in-Bay disposal to date Beneficial Reuse Beneficial Reuse – ~20 million cy has already been reused – Current and near-term capacity for many millions cy more Beach Nourishment Beach Nourishment – ~1 million cy sand placed nearshore for Ocean Beach demo project – EPA/USACE preparing to designated official reuse site “SF-17” In-Bay Disposal In-Bay Disposal – Significantly reduced: disposal limits have been met every year – Mostly done successfully within Environmental Work Windows Ocean Disposal Ocean Disposal – Successful low-impact alternative – Over 15 million cy diverted from in-Bay disposal to date Beneficial Reuse Beneficial Reuse – ~20 million cy has already been reused – Current and near-term capacity for many millions cy more Beach Nourishment Beach Nourishment – ~1 million cy sand placed nearshore for Ocean Beach demo project – EPA/USACE preparing to designated official reuse site “SF-17” The LTMS Transition is On Track How Are We Doing?

8. Short Term: Short Term: – Escalating costs for: Ocean disposal Hydraulic offloading at reuse sites – Flat or decreasing dredging budgets Long Term: Long Term: – Sediment deficit (habitat erosion, Bay water quality) – Climate change – especially sea level rise – will accelerate habitat loss and other changes Short Term: Short Term: – Escalating costs for: Ocean disposal Hydraulic offloading at reuse sites – Flat or decreasing dredging budgets Long Term: Long Term: – Sediment deficit (habitat erosion, Bay water quality) – Climate change – especially sea level rise – will accelerate habitat loss and other changes But Today We Face New Challenges that the LTMS Plan Did Not Foresee:

9. The New World: Sediment Deficit Changed Situation Point San Pablo, mid-depth, Dave Schoellhamer, USGS

10. Oakland Museum Creek Guide Sediment Supply Shift: from the Delta to local tributaries Changed Situation

11. Area subject to high tide with 16 inches of sea level rise 55 inches of sea level rise and Current 100-year flood plain Changed Situation The New World: Sea Level Rise

12. Shorelines, Marshes and Beaches need sediment to keep up with sea level rise PWA & PRBO in review

13. Sand mining removing sand Patrick Barnard & Rikk Kvitek Sand appears slow to replenish

14. Ocean Disposal Removes Sediment from the System

15. Is the LTMS Approach to Sediment Management too Narrow? Minimizes in-Bay disposal Emphasizes large-scale tidal wetland projects Ocean disposal for remaining dredged material Or Does It Need to be Re-Framed?

16. How can LTMS help in this New World? RSM planning: coordinate sediment sources and needs beyond navigation dredging? – Sand miners – Flood control districts – Watershed management Less reliance on mega-projects? New kinds of Beneficial Reuse, including in-Bay? New policies/laws to facilitate reuse? Your Ideas?

17. LTMSRSM While still working under the LTMS Management Plan for dredging: – Funding local tributaries study – Funding sediment modeling (“UnTRIM” combined with “Sedmorph” and “SWAN”) – State of the Sediment Workshop 2010 – Spring 2011 RSM Stakeholders Workshop – Stakeholder listening sessions – Work toward 2010 program review
