We manage everyday and not-so-every day emergencies in San Francisco:

• Emergency Services: We help San

Francisco prepared for any emergency and we coordinate response and recovery.

• Emergency Communications (9-1-1):

When people in San Francisco have police, fire, or medical emergency our dispatchers are the first people they call.

• Homeland Security Grant Management:

We manage homeland security priorities for the San Francisco Bay Area.

Emergency Preparedness Coordination

– DBI Emergency Operations Plan – Conduct training as Disaster Service Workers – Specialized training for Safety Assessment Program – Building Occupancy Resumption Program (BORP)

Mitigation: DBI’s Programs

9

• Programs
• Parapet Safety Program (1972)
• Unreinforced Masonry (1989)
• Buildings Program (1992)
• Soft Story Retrofit Program (2014)
• Voluntary seismic retrofit

Mitigation: Building Occupancy Resumption Program (BORP)

10

• Allows building owners to arrange for

private post-earthquake inspection

• Requires contracting with qualified

engineers

• Includes a building-specific inspection

plan

• Deputizes engineers to post buildings

after quake

In a serious emergency, city services will be impacted, so a basic rule

• f thumb is to be able to

take care of each other for 72 hours before help arrives.

72 HOURS

What You Can Do to Prepare

13

• Discuss all possible exit routes

from each room, building and neighborhood

• Decide where you will reunite

after a disaster.

• Conduct emergency drills and

practice “DROP, COVER and HOLD”

• Always keep your car’s gas

tank at least half full

Preparedness: Property Owner

14

How can I prepare my property?

• Owner hires a civil or structural

engineer to develop a plan/report identifying how occupants can safely enter the building to remove their possessions.

• Owner hires contractor whose staff

retrieve possessions for the tenants.

Structural Home/Building Preparedness

15

• Evaluate your structure
• Underlying soil

conditions

• Age and type of

construction

• Structural /connection

condition

• Remodeling impact
• Investigate retrofit options
• Compare retrofit costs with

insurance premiums

Bolt Sill to Foundation Using Square Plate Washers

16

• Square plate washers

perform better in quakes than the round one that has been replaced here.

• They also make the

tightening of expansion bolts easier.

Plate washers must be a minimum

• f 2” x 2” x 3/16” thick

Strengthen Cripple Walls

17

• A cripple wall is generally the

weakest part of older building because it has insufficiently strong sheathing materials.

• This can cause full or partial

collapse in an earthquake.

• These areas can be

strengthened for relatively low cost by correctly applying plywood sheathing to the cripple walls.

Crawl Space Cripple Wall First Floor

Non-Structural Mitigation

18

• Parapets
• Chimneys
• Water heaters
• Light fixtures
• Furniture
• Cabinets
• Appliances
• Electronics

Preparing Your Home: Water Heater

19

• Earthquake strapping of water

heaters

• California law requires your water

heater be properly braced so it won’t tip over in an earthquake

• Source of water during emergency

Preparing Your Home: Smoke Alarms

20

• Be sure your home’s street number is

visible from the street, so emergency vehicles can find you.

• Install a smoke alarm in each sleeping

room

• Provide a smoke alarm outside of each

sleeping area

• Install a smoke alarm on each additional

living level.

• Keep at least one ABC type fire

extinguisher on each level of your home.

Response: City/At-Large Early Stages

21

• Evacuating/extracting people

from buildings

• Route recovery/traffic

control

• Mitigation of immediate

public hazards

• Restoration of critical

services

• Lighting of field work sites
• Debris clearance
• Inspection of critical facilities

DBI’s Response

22

• Coordinate with DPW for

inspection of critical facilities and City buildings

• Supervise inspection of private

buildings

• Verify red-tagged building status
• Re-inspect buildings under

construction

• Issue emergency repair permits
• Inspect earthquake building

repairs

• 72 hour window

DBI Manages Safety Assessment

23

Resident’s Response

24

• Listen to public messaging

(KCBS/KGO radio)

• If safe to do so, stay at property
• Check in with neighbors
• Call 911 only for emergencies
• Carry out preparedness plan

Utilities: Natural Gas

25

• Train family to turn off utilities, if

necessary

• Teach children to identify the smell of

gas Turn off gas, if: – you smell leaks & are unsure – your meter wheels are spinning

• Be aware that you may not have

service for weeks

Utilities: Electricity

26

Turn off electricity, if: – you smell gas leaks – wires are broken – walls are badly damaged

27

Turn circuit breakers to OFF position

28

Or pull fuses

Utilities: Water

29

Turn off water if house is flooding or if water is contaminated Shut Off Water, If Necessary

• Locate water shutoff
• Insert tool in hole & remove

cover

• Turn water OFF

Road to Recovery

30

• Rapid organized response by DBI to conduct building

damage assessment post event

• Request for Mutual Aid to augment DBI personnel as

approved by the Mayor

• Timely processing of repair permits
• DBI inspection of damage repairs
• Swift resumption of new construction plan review and

inspection

Remind Yourself

31

• Drill with your family at least
• nce a year; earthquake

anniversaries are good reminders

• Maintain first aid and other

emergency skills

• Check family emergency

supplies, replenish them as needed
