• 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
![Page 11: Preparing Your Home & Property for the Next Earthquake Sean OMara, Department of Emergency Management Ron Tom/Mike Mitchell, Department of Building Inspection.](https://reader038.fdocuments.us/reader038/viewer/2022110213/56649d6e5503460f94a4ffaa/html5/thumbnails/11.jpg)
In a serious emergency, city services will be impacted, so a basic rule of thumb is to be able to take care of each other for 72 hours before help arrives.
72 HOURS

Phone: 415-558-6088
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
![Page 14: Preparing Your Home & Property for the Next Earthquake Sean OMara, Department of Emergency Management Ron Tom/Mike Mitchell, Department of Building Inspection.](https://reader038.fdocuments.us/reader038/viewer/2022110213/56649d6e5503460f94a4ffaa/html5/thumbnails/14.jpg)
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.
![Page 15: Preparing Your Home & Property for the Next Earthquake Sean OMara, Department of Emergency Management Ron Tom/Mike Mitchell, Department of Building Inspection.](https://reader038.fdocuments.us/reader038/viewer/2022110213/56649d6e5503460f94a4ffaa/html5/thumbnails/15.jpg)
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
![Page 16: Preparing Your Home & Property for the Next Earthquake Sean OMara, Department of Emergency Management Ron Tom/Mike Mitchell, Department of Building Inspection.](https://reader038.fdocuments.us/reader038/viewer/2022110213/56649d6e5503460f94a4ffaa/html5/thumbnails/16.jpg)
Bolt Sill to FoundationUsing 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 of 2” x 2” x 3/16”
thick
![Page 17: Preparing Your Home & Property for the Next Earthquake Sean OMara, Department of Emergency Management Ron Tom/Mike Mitchell, Department of Building Inspection.](https://reader038.fdocuments.us/reader038/viewer/2022110213/56649d6e5503460f94a4ffaa/html5/thumbnails/17.jpg)
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
![Page 20: Preparing Your Home & Property for the Next Earthquake Sean OMara, Department of Emergency Management Ron Tom/Mike Mitchell, Department of Building Inspection.](https://reader038.fdocuments.us/reader038/viewer/2022110213/56649d6e5503460f94a4ffaa/html5/thumbnails/20.jpg)
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.
