1. Street Design/Traffic Calming Changes and Challenges Facing the SFFD
July 18, 2017

2. Examples of Traffic Calming Measures

3. Speed Humps vs Speed Cushions

4. Concerns with Some Traffic Calming Measures
Response Times
2. Operational Issues
3. Equipment Limitations

5. Challenges of San Francisco
Topographical
Wood construction
Overhead electrical wires
Zero lot lines
Narrow streets
Delivery trucks/ double parking
Muni wires, buses & traffic
Wind speed
Rapid fire spread
Earthquakes

6. Operational Challenges
Ladder placement
Hose leads
Collapse zone
Hydrants
Aerial operations
How many wood ladders and why (insulation, weight and size) Hills and History
Hose leads: hydrant to fire and into the building and out of the way of the ladders. Hoses all over the front of the building/ no place to put a ladder
Collapse zone: Command post and VEHICLES out
Hydrants: location, distance and visual
Aerial operations, MUNI wires and live wires, outriggers, reinforced ground
Fire ground operations: Rigs need to pass each other
We adapt and overcome – however, it is not recommended to continue to create than optimal conditions

7. Operational Challenges

8. New Vehicle Spec Reduced Profile
Many variables involved
Fire load
Time of day
Wind conditions
Hazards
Traffic
4000 or so missing calls are canceled in route
