Existing needs to manage flood risk in the U.S. are underserved by
available flood hazard information. This contributes to an alarming
escalation of flood impacts that amount to hundreds of billions of dollars
per year and countless disrupted lives and affected communities. Making
information about flood hazards useful for the range of decisions by
actors that dictate the consequences of flooding poses many challenges.
This dataset contains a collection of flood hazard mapping layers for two
sites in Southern California: Newport Bay and the Tijuana River Estuary.
The flood hazard data layers were created using a Collaborative Flood
Modeling (CFM) approach, whereby researchers and end-users at the two
coastal sites co-developed fine-resolution flood hazard models and maps
responsive to decision-making needs.
Newport Beach: Historical Event Flood Depth (2005) This map layer contains
the resulting flood depth (US feet) from the extreme high tide event
that occurred on January 10th 2005. NB_Historical_Flood_2005.tif
Newport Beach: 1% Annual Chance Flood Depth (2015, 2035, 2050) These map
layers contain maximum flood depths (US feet) produced by 1% AEP
events occurring under 2015 sea level conditions. Flood drivers considered
are tide, streamflow, wave overtopping, and rainfall. The displayed flood
depths are not the result of one event, but the combination of flood
depths produced by each flood driver as occurring independently and
modeled separately. NB_1pct_Chance_Flood_Depth_2015.tif

Newport Beach: Chance of Flooding (2015, 2035, 2015) These map layers
contain annual chance of flooding over ankle depth under 2015, 2035, and
2050 sea level conditions, and the chance of flooding over 10 years from
2015, 2035, and 2050. Flood causes considered are tide, streamflow, wave
overtopping, and rainfall. The displayed probabilities of flooding are not
the result of one event, but the combination of probabilities from events
from different flood causes, with different chance, occurring
independently, and modeled separately. NB_Chance_of_Flooding_2015.tif
NB_Chance_of_Flooding_2035.tif NB_Chance_of_Flooding_2050.tif Newport
Beach: Chance of Road Blockage (2015, 2035, 2015) These map layers contain
probability of road blockage to sedans under 2015. 2035, and 2050 sea
level conditions. A 1 ft fording depth is used as a cutoff to mark
flooding unsafe for sedans. Flood drivers considered are tide, streamflow,
wave overtopping, and rainfall. The probabilities of flooding are not the
result of one event, but the combination of probabilities from events from
different flood drivers, with different exceedance probabilities,
occurring independently, and modeled separately.

NB_Chance_Road_Blockage_2050.tif Newport Beach: "King Tide with
Rainfall” Flood Depth (1/2”, 1”) These map layers contain the resulting
flood depth from two rainfall events (approximatley 0.5" and
1") coinciding with a King Tide during 2015 climate and sea level
conditions. The probability of a 0.5" rainfall event to coincide with
the King Tide is on average once every 278 years, or 0.36% annually, while
the probability of a 1" rainfall event to coincide with the King Tide
is on average once every 1391 years, or 0.072% annually.

NB_King_Tide_with_1in_Rainfall_Flood_Depth.tif Newport Beach: Hours of
Inundation Per Day (2015, 2035, 2015) These map layers contain duration of
flooding in hours for current conditions (2010, 2015) and future
conditions (2035, 2050) for two scenarios: 1) in the event of a 1% annual
chance tide, and 2) under average daily duration of inundation in the
Newport Upper Bay based on 2010 sea level observations and projected 2035
and 2050 sea level rise conditions. NB_1pct_Tide_Flood_Duration_2015.tif

of Flooding (2015/2035/2050) These map layers contain the primary cause of
flooding producing the deepest flood depth locally in the case of a 1%
annual chance event occurring under 2015, 2035, and 20150 sea level
conditions. The displayed flood extent is not the result of one event, but
the combination of flood extents produced by each flood cause as occurring
independently and modeled separately. NB_Causes_of_Flooding_2015.tif

Beach: 1% Annual Chance Flood Depth with Proposed Flood Wall and Flood
Wall Failure These map layers contain the resulting flood depth (US feet)
from a 9.1 ft NAVD88 tide after seawalls surrounding the Balboa Isles have
been capped to 9.5 ft NAVD88. Based on the California Coastal Commission
intermediate sea level rise projections of 2015 (IPCC scenario A1B), a
9.1 ft NAVD88 tide has a 1% chance of occurrence in the year 2050. In
other words, it represents the 100 year return period tide for the year
2050. We also show the flooding resulting from a localized failure of the
capped wall on Balboa Island during a 7.5 ft tide.

Tijuana River Valley: Flood Depth (1983, 1% AEP, 20% AEP) These map layers
contain maximum flood depths (meters) produced by three scenarios: 1) a
historical 1983 flood, 2) a 1% AEP event occurring under 2015 sea level
conditions, and 3) a 20% AEP event occurring under 2015 sea level
conditions. Flood drivers considered are streamflow from the Tijuana River
and it's canyon tributaries in the Tijuana River Estuary
(Smuggler's Gulch and Goat Canyon), as well as stormtide
conditions.The displayed flood depths are not the result of one event, but
the combination of flood depths produced by each flood driver as occurring
independently and modeled separately. TRV_1983_Flood_Depth.tif

Tijuana River Valley: Flood Force (1983, 1% AEP, 20% AEP) These map
layers contain maximum flood force (m2/s) produced by three scenarios: 1)
a historical 1983 flood, 2) a 1% AEP event occurring under 2015 sea level
conditions, and 3) a 20% AEP event occurring under 2015 sea level
conditions. Flood drivers considered are streamflow from the Tijuana River
and it's canyon tributaries in the Tijuana River Estuary
(Smuggler's Gulch and Goat Canyon), as well as stormtide
conditions.The displayed flood forces are not the result of one event, but
the combination of flood depths produced by each flood driver as occurring
independently and modeled separately. TRV_1983_Flood_Force.tif

Tijuana River Valley: Flood Shear Stress (1983, 1% AEP, 20% AEP) These
map layers contain maximum flood shear stress (kg/m2) produced by three
scenarios: 1) a historical 1983 flood, 2) a 1% AEP event occurring under
2015 sea level conditions, and 3) a 20% AEP event occurring under 2015 sea
level conditions. Flood drivers considered are streamflow from the Tijuana
River and it's canyon tributaries in the Tijuana River Estuary
(Smuggler's Gulch and Goat Canyon), as well as stormtide
conditions.The displayed flood shear stresses are not the result of one
event, but the combination of flood depths produced by each flood driver
as occurring independently and modeled separately.

Chance of flooding This map layer contain annual chance of flooding over
ankle depth under 2015 sea level conditions. Flood causes considered are
storm tides, canyon flows, and Tijuana River flows with a range of return
periods, from 1 to 100 years. The displayed probabilities of flooding are
not the result of one event, but the combination of probabilities from
events from different flood causes, with different chance, occurring
independently, and modeled separately. TRV_Chance_of_Flooding.tif
Tijuana River Valley: Flood Management Strategies These map layers
represent two management strategies to deal with flooding in the Tijuana
River Valley. The first strategy looks at the impact of channel dredging
on a 20% AEP flood event. The second one looks at the impact of removing
historically placed fill material downstream of Hollister Bridge (locally
known as Borwn Fill) on a hindcast of the 1983 flood event.
TRV_Channel_Dredging.tif TRV_Fill_Removal.tif Tijuana River Valley:
Implications of Flooding on Health This map layer contains depth and
locations of water that did not freely drain to the Pacific Ocean by
overland flow following the 1% AEP Tijuana River flood. The residual flood
depth serves as a surrogate for standing water which could represent a
public health risk since standing water increases mosquito activity.
