Ground Water Map◦ USDA Soils Data Mart: Depth to Water Table

Liquefaction Susceptibility◦ USDA Soils Data Mart: Liquid Limit, Plasticity Index, Water Content One-Third Bar

Landslide Susceptibility◦ USDA Soils Data Mart: Parent Material Name, Representative Slope, Depth to Water Table

The final hazard maps were used as direct imports into the Hazus study region for the GBS evaluations and also as a source layer to populate the corresponding attribute fields in the UDF inventory. Instead of using the single value at the location of the UDF point, a weighted average of all hazard values within the parcel was used to better estimate the average conditions throughout a building structure.

The updated hazard maps are polygon feature classes stored in an ArcGIS Personal Geodatabase and the attributes are stored in a field named “TYPE”. The specific schema requirements to build the HazusHazards Map database are available in the Hazus-MH 2.1 Earthquake User’s Guide Appendix K.

NEHRP Soils Classification

The NEHRP soil classification is based on Table B.1 in the Hazus 2.1 Earthquake User’s Manual where the soil types ‘A’ trough ‘F’ are equated to ranges of values of shear wave velocity (Vs). The USGS Earthquake Hazards Program provides Vs30 maps, where the value of the Vs30 is the average shear velocity down to 30 meters. These Vs30 values were downloaded from the USGS site as an ASCII text file and exported to a point shapefile. Then the ArcGIS Create Thiessen Polygons tool was used to generate a seamless polygon shapefile from the points and attributed with the associated soil type based on the Vs30 values.

Soil Type General Description Vs (m/s)A Hard Rock Vs > 1500B Rock 760 < Vs ≤ 1500C Hard and/or stiff/very stiff soils; most gravels 360 < Vs ≤ 760D Sand, silts, and/or stiff/very stiff clays, some gravels.

F Needs specific calculations

Ground Water Map

The ground water depths are based on the Depth to Water Table attributes extracted from the USDA Soils Data Mart database. This dataset provides the depth to the water table in meters for each of the SSURGO (Soil Survey Geographic) polygon features. The only data manipulation required was to convert the depth provided in centimeters to the equivalent value in meters.

Liquefaction Susceptibility

The liquefaction susceptibility classifications were determined based on methods presented by Jonathan D. Bray from the University of California, Berkeley. In this journal article it is presented that correlations between the plasticity index, liquid limit and water content (1/3 Bar) can be used to determine a soils susceptibility to liquefaction.Bray, Jonathan D., and Rodolfo B. Sancio, “Liquefaction Susceptibility of Fine-Grained Soils”, Department of Civil Engineering, University of California, Berkeley, USA. ICGEE 2004.

Landslide Susceptibility

Based on Table 4.15 of the Earthquake User’s Manual, the landslide susceptibility classifications can be determined by a combination of geologic group (A, B or C) and slope angle (in degrees) in either wet or dry conditions. From the Soils Data Mart database the Parent Material Name was used to determine the geologic group, the Representative Slope was used to determine the appropriate degree range and the Depth to Water Table was used to determine which locations had groundwater at the ground surface. Combining these three datasets, Table 4.15 was then used to determine the landslide susceptibility classification for each soil.

Load into HazusGBS Study◦ Load .mdb with hazard maps into study region.◦ Choose each features class to overwrite the

standard ‘risk’ defaults for each parameter.UDF Study◦ Use polygon hazard maps to assign a ‘risk’ value

to each building.Can use single point or a weighted average per building footprint or parcel.

◦ Import these values with the UDF table.

How To Technical Series

2011 BCAR Re-Engineered Depth-Damage Curves in Hazus

James Mawby, CFM

June 2013

www.dewberry.co

m

Background

• FEMA’s BCA is the tool to determine economic viability of

mitigation projects.

• Hazus, although similar, is not the same. But what benefit

might exist to use the same curves in Hazus as exist in

BCA?

• Notably, BCA includes newer curves for coastal residential

damages.

• Here’s an attempt to get the new BCA curves into Hazus.

www.dewberry.co

m

Step 1 - Reference

• Step 1 – assemble references

www.dewberry.co

m

Step 2 – Hazus Curves

• Where are the Hazus curves?

– Front end (Assumption - Beneficial for adding a curve or two)

www.dewberry.co

m

Step 2 – Hazus Curves

• Where are the Hazus curves?

– Back end (Assumption - Beneficial for adding Multiple Curves)

www.dewberry.co

m

Step 3 – Curve & dB Structure

• Review / Understand Curve Tables and Relationships

– Structure curves, Contents Curves, Inventory Curves, Other…etc

– Which tables relate to others

Always wise to back-up files before editing

www.dewberry.co

m

Step 3 – Curve & dB Structure

• Review / Understand Curve Tables and Relationships

– Example from BCAR

www.dewberry.co

m

Step 4 – Interim Curve Table Development

• Mass population or addition of curves

– Use of Excel

• Drag & Fill to propagate addition of sequentially numbered “DmgFnID”

• Copy/Paste to propagate values in “Occupancy” field

• Copy/Paste to fill % damage in each depth value column

www.dewberry.co

m

Step 4 – Interim Xref Table Development

• Mass population or addition of curves

– Use of Excel

• Copy/Paste to propagate values in “SOccupId” field

• Drag & Fill to propagate addition of sequentially numbered “DmgFnID”

• Copy/Paste to fill TRUE/FALSE values

Most curves apply to RES1, RES3A & RES3B also RES2 but not shown here.

www.dewberry.co

m

Step 5 – Run a Test

• Load the Interim Tables in Excel into Access dB

• Replace the default Access dB with the revised

• Perform Region Creation

• Perform Region set-up as per desired

– I chose to perform a User-Defined Facility (UDF) exercise

www.dewberry.co

m

Step 5 – Run a Test

• Tested with User-Defined Facilities (UDF)

– Where user can define DmgFnID’s in UDF table

User defines the DmgFnID in these fields

www.dewberry.co

m

Step 5 – Examine Results

• Initial testing revealed that the TRUE/FALSE values of the

XREF Table were not set properly.

– Assumption: it was initially assumed that if the DmgFnID was

defined in the UDF Table, the model would use it.

– This was not true; the stock-set default curves were used.

– TRUE/FALSE settings were adjusted and results for the added

curves were obtained.

www.dewberry.co

m

Step 5 – Examine Results

• Visual Comparison

– Structure Damage, Coastal V-Zone, RES1

The check-boxes are controlled by the TRUE & FALSE values of the Xref Table in flDmRsFn.mdb - Access dB

What’s Next?

• Question Results

– Were the curves entered and translated correctly?

– Were appropriate checkboxes (TRUE/FALSE) settings used?

– Can dollar values be verified with Individual Assistance (IA) data?

– Do curves require adjustments based on actual losses?

– Do we need curves for floating buildings?

• How does this relate to BCA?

– Is there ever a chance Hazus and BCA might be one in the

same?

– How does adding these BCA curves to Hazus promote and

possibly assist such an integration?
