6 Hazus Pilot Study Flood, Hurricane, Earthquake* *This presentation will focus on Earthquake Hazard Map updates.

7 Project Scope Analysis utilizing building specific data Building footprint locations Attributes: Occupancy, cost, stories, year built, design type, etc. Hazard Data Flood: engineered depth grids Hurricane: no updates Earthquake: updated hazard maps

8 BUILDING FOOTPRINTS with parcel based attributes

9 Building Analysis Locations

10 Common Difficulties In most cases building footprint data cannot be used without some manual editing.

11 FLOOD STUDY

12 Flood Depth Grids Multi-profile depth grids based on updated engineered models.

20 EARTHQUAKE STUDY

21 Hazard Maps NEHRP (National Earthquake Hazards Reduction Program) Soil Classification USGS EQ Hazards Program Global Map Server: Vs30 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 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 Hazus Hazards Map database are available in the Hazus-MH 2.1 Earthquake User s Guide Appendix K. 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.

22 NEHRP Soils Classification Soil Type General Description Vs (m/s) A Hard Rock Vs > 1500 B Rock 760 < Vs 1500 C Hard and/or stiff/very stiff soils; most gravels 360 < Vs 760 D Sand, silts, and/or stiff/very stiff clays, some gravels. 180 < Vs 360 Having average blow counts of 15 N < 50 or average shear strength of 50 kpa S 100 kpa E Having thickness lower than 3 meters and PI > 20, Vs < 180 w 40% and s u < 25 kpa soft clay F Needs specific calculations 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.

23 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.

24 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.

25 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.

26 Load into Hazus GBS 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.
