Public Safety Planning with GIS

Beacon GIS, LLC All Rights Reserved. www.BeaconGIS.net

Goals

Learn to work with emergency services Learn the jargon, abbreviations, and

acronyms Be familiar with their particular

performance objectives Discern ways of using GIS to aid their

decision making process.


Cities & Towns can be proactive Planning Zoning Engineering Comprehensive plans Future land use


Emergency Services are reactive

Police, Fire, EMS, EM


What do I know?


Working Together

Are your city managers and department heads in the same building?

And what about the…. Police chief? Fire Chief? EMS Director? Emergency Management Coordinator?


Working together

Do your comprehensive/strategic plans… Include emergency services? More than just an description of existing

assets and or current production? Does it include future planning for these

services as your community is projected to change?

Does it include GIS analysis mapping for emergency services?


Emergency Services Planning Where you are now (Current Conditions

Evaluation) Where you’re going (Jurisdictional

Assessment) Where you need to be (Future Needs

Planning)


Law Enforcement

Crime Analysis Resource Distribution Demographics & Socioeconomics Response Performance


Law Enforcement

Crime Analysis Spatial Distribution of incidents Density of events Relative crime risk Offender behavior in time & Space Geographical profiling ‘crime travel’


Law Enforcement

Resource Deployment Per capita

100 most populous cities avg. 22 officers per 10,000 population.

Minimum-staffing Management/labor agreement. May disregard

peak loads Authorized level

Budgetary Workload based (aka Peak load staffing)

Single or double staffed cars


Law Enforcement

Demographics & Socioeconomics Who commits what crime Who uses the police

Age, race, ethnicity Income, housing prices, vacancies

Where is crime committed In addition to above… Types of businesses/property


Law Enforcement

Response Performance “Differential Police Response” based on

research. A rapid response to a serious crime = arrest <

5% Most crimes w/ no witnesses/evidence citizens

willing to phone a report. Biggest factor: The response matched

community expectation even if lengthy. No national standards, performance based on

incident outcomes rather than time responsiveness.

9 – 12% of the ‘effective’ population will need an ambulance.

Based upon land use Varies from high

risk (industrial property) to low risk (large lot single family residential)

Building size and construction translate into Needed Fire Flow Rates.

Suburban 500-1000/SqMi, 10mins/10 FF, 80th percentile

Rural < 500/SqMi, 14 mins/9 FF, 80th percentile

Remote Travel > 8 miles, No time goal/6 FF


Effective Firefighting Force

Fires require multiple apparatus from a number of spatially distant stations.

Usually 2 Engines, 1 Truck, 1 EMS, deputy chief (13-15ffs)

Can show apparatus or staff levels
