Master Plan Nashua Fire Rescue, NH
ISO Response Performance
The Insurance Services Office (ISO) is a data analytics organization that provides insurance carriers with a
classification rating of a local community's fire protection. The Property Protection Class (PPC®) score or
rating classifies communities based upon an overall scale of 1 (best protection) to 10 (no protection) and
assesses all areas related to fire protection. These areas are broken into four major categories, which include:
emergency dispatch and communications (10% of the rating), water supply system and distribution
capabilities (40%), the fire department (50%), and Community Risk Reduction efforts (an additional 5.5%
credit is available above 100%).
As part of the Master Planning Process, ESCI conducted a complete benchmarking assessment for Nashua
to identify key performance measures based on the Insurance Services Office (ISO) criteria. This report has
been submitted to Nashua Fire Rescue as a separate report. These criteria were graded based on past and
current performance and deficiencies prioritized based on the greatest impact on overall score improvement
versus the cost of those improvements.
Engine Company Performance
A key area of credit towards a jurisdiction’s PPC® score is the degree to which structures protected by the
fire department fall within a 1.5 road-mile service area of a fire station. This 1.5 road-mile standard is used to
estimate a 4-minute travel time for first responding units as required by NFPA 1710. In Figure 74, an analysis
was completed for current fire stations with areas in yellow indicating those structures within a1.5-mile drive.
Based on the ISO engine company travel criteria, approximately 50% of Nashua is included within the 1.5-
mile travel distance.
