CNU Emergency Response & Street Design Initiative
What is the Initiative?
• Making less than 20 foot
clear legal through code
changes
• Building an Alliance with
Emergency Responders
• Making the Public Health
Case for Narrower
Connected Street
Networks

Narrower streets are safer streets, butFire operations must be accommodated

Average Citywide Response Time and Connectivity Ratio
CNU Emergency Response & Street Design Initiative
Conclusions
• Degree of connectivity directly affects Fire Station service area size
– Higher connectivity ratios = larger service areas
• Larger service area distributes fixed costs over more households
• Fire station costs are fixed
• Good connectivity = Financial efficiency

Response time = average speed * response
distance
CNU Emergency Response & Street Design Initiative
Response time = average speed * response distance
To improve response times
Option 1: Increase speeds
Option 2: Reduce response distances• Keep homes closer to existing firehouses• Design shorter routes from firehouse to homes
