3. ART and FHWA Background
Adapting to Rising Tides Project
Partnership between SF Bay Conservation and
Development Commission (BCDC) and NOAA
Coastal Services Center
Increase preparedness and resilience of Bay Area
communities to sea level rise
Evaluate shoreline impacts,
vulnerabilities and risks,
identify adaptation strategies
and planning tools
4. ART and FHWA Background
Federal Highway Administration Risk Assessment
Conceptual Model
MTC, Caltrans, and BCDC collaborated on
subregional planning pilot project
Provides a framework for conducting risk and
vulnerability assessments
Test Federal Highway Administration (FHWA)
conceptual Risk Assessment model to assess SLR
risks to transportation infrastructure
Portion of Alameda County shoreline selected for
study area
5. Pilot Study: Alameda County
One of Several Pilot
Bay
Studies to test the FHWA Bridge
Conceptual Model Previous
(Vulnerability of USGS/BCDC
Alameda Maps
Transportation Assets to Island
Climate Change)
Alameda County: Diverse Airport
Range of Shore
Protection and
Transportation Assets
Project Extent: San Mateo
Bridge
Emeryville to Union City Salt
Ponds
6. Federal Highway
Administration
Vulnerability and
Risk Assessment
Conceptual Model
1. Data Asset Inventory
2. Asset Screening and
Prioritization
3. Climate and Shoreline
Information
4. Vulnerability Assessment
5. Risk Assessment
6. Next Steps/ Adaptation
Strategies
8. Shoreline Asset Inventory
Identify the topographic feature that controls
inundation landward of shoreline (e.g., levee, road
embankment, beach, etc)
May not be the true “shoreline” (e.g., MHW, etc)
Shoreline Categories
1. Engineered Flood Protection Structures
2. Engineered Shoreline Protection Structures
3. Non-Engineered Berms
4. Wetlands
5. Natural Shorelines (Non-Wetland)
Shoreline delineation will be used later to determine
vulnerability to inundation
11. Sea Level Rise Scenarios for
Inundation Mapping
Sea Level Rise
o 16” (high-end 2050)
o 55” (mid-range 2100)
Inundation Map Scenarios
o MHHW + 16”
o MHHW + 55”
o 100-yr SWL + 16”
o 100-yr SWL + 55”
o 100-yr SWL + 16” + wind/wave
o 100-yr SWL + 55” + wind/wave Map: Geografika
Include depth of inundation and hydraulic connectivity
12. Inundation Scenarios
MHHW – Mean Higher High Water. Typical daily high tide.
Frequent inundation.
100-yr Stillwater Level (SWL) – Extreme high tide. Very rare
event. Also, the 1%-annual-chance tide level. No wave or local
meteorological effects.
100-yr SWL + wind and wave effects. Includes wind setup and
wave setup at the shoreline. Includes wave height effects (but
not wave runup or overtopping). Extreme coastal flood event.
wind/wave
13. Inundation Mapping Inputs
Topography: 2m Digital Elevation Model (DEM) using 2010 CA
Coastal LIDAR (USGS)
Daily and extreme tide levels – USGS TRIM2D (Knowles, 2009)
Storm wave scenarios – FEMA MIKE21 hydrodynamic model:
wind setup, wave setup, wave height (DHI, 2010)
Hydraulic Connectivity – resolved using NOAA CSC
methodology (Marcy et al., 2011)
Depth of Inundation grids – depth
along shoreline and at transportation
assets
14. Ocean Protection Council LIDAR
USGS 2010
Complete Coverage
to 10 m Contour
2 m DEM used for
inundation
mapping
Resolves Levees
15. USGS TRIM2D Modeling
Hydrodynamic Model
Extraction Points
100-yr Water Level Time Series
(Detrended = SLR trend removed)
Estimate MHHW and 100-yr SWL at each extraction point
17. NOAA Methodology
Sea Level Rise Viewer (Marcy et al, 2011)
Hydraulic Connectivity
Inputs:
o Water Surface
Elevation (DEM)
at Shoreline
o Transect Definition
o DEM (at a resolution
that resolves
shoreline features)

for each Scenario:
o Is it Inundated?
o Max Depth of
Inundation?
Distance from asset to
overtopped shoreline
Percent of shoreline
overtopped
23. Risk Profiles
Road Networks
o Interstates/Freeway
o Bridges/Tubes
o Local Streets
Transit
o Bus Routes
o Bart Alignments
o Rail Corridors
