adding additional units to the system. Given the annual call volume, call concurrency rates, and UHUs, the
fire department should have ample time for additional duties such as training, career development, and pre-
fire planning.

General ISO Considerations
The City of Nashua possesses the ability to dramatically improve its ISO PPC® rating and potentially receive
an ISO 1 rating. A review of the fire department's latest ISO survey indicates that significant credit was lost
within the emergency communications, staffing, water supply, deployment, and community risk reduction
sections of the evaluation and subsequently contributed to a rating of 82.04 or a low ISO Class 2 rating.
Resource Concentration

Water Supply and Hydrant Locations
Access to water is a fundamental requirement for fire suppression in urban settings. Without an adequate
supply of water, fire suppression operations are challenging. Additionally, the access point for this water
supply must be located close enough to the structure to allow for rapid access by the fire department.
Next, fire hydrant coverage within Nashua is displayed using ISO requirement that structures must be located
within 1,000 feet of a fire hydrant.
