Background: Sea Level Rise
2/3 of California’s
sea level rise
impacts will be felt
in the Bay Area
•Already seen:
+8 inches SLR
•Projected by 2050:
+12 to 32 inches
•End of century:
10+ feet?
36” SLR + 100-year storm surge

Background: Groundwater Rise
• Infiltration & corrosion of
underground infrastructure
• Damage to roads and
structures
• Flooding from multiple
sources including emergent
groundwater
• Contaminated sites
• Increased liquefaction risk

Background: Liquefaction
•Areas most at risk of
liquefaction are same
areas at risk of rising
groundwater
•Rising groundwater may
increase risk of
liquefaction

Background: Regional Problem & Solutions

•Inconsistent science
•Competition not collaboration for
funding
•Loss of wetlands
•Difficult to measure collective progress

Estuary flood and adaptation projects
to protect and restore water quality,

San Leandro operational landscape unit
(one of 30 OLUs in Bay Area)
Working Group: Objectives
•Prepare for flooding, sea level and
groundwater rise
•Prioritize habitat, nature-based solutions and
green infrastructure
•Consider sediment management
•Improve recreational access and air quality
•Provide benefit to residents and vulnerable
communities
•Contribute to economic opportunities
•Advocate for training and skill development
for underserved communities

Working Group:
Focus Areas
• West Oakland – wave exposed with
seawalls, quays and subtidal habitat
• Oakland-Alameda Estuary – highly
urbanized dominated by seawalls
• San Leandro Bay – small embayment
protected from wave action, patches
of marsh habitat and wide mudflats
• Alameda Bayshore – wave-exposed
with beaches
• Bay Farm Island & Oyster Bay – high
wave action surrounded by deep
subtidal habitat
