MERIDIAN FIRE DEPARTMENT
STAFF REPORT
DATE: 9/20/2021
TO: Sonya Allen
REVIEWER: Joseph Bongiorno, Deputy Chief of Prevention 208-888-1234
SUBJECT: H-2021-0065
PROJECT NAME: Aviator Springs Subdivision
Fire Department Summary of Report:
Overview: This project can be serviced by the Meridian Fire Department.
1. Fire Response Time Travel time from nearest fire station (level of service expectation goal = 5 minutes)
This development currently falls outside the 5 minute response time area as shown on the priority
growth map. It will be in the 5 minute area once fire station 8 is constructed and staffed in late
summer of 2023. It is currently nearest to Fire Station 2. This fire station is approximately 4.5 miles
from the project.
2. Resource reliability Current reliability of closest fire station (Reliability Goal is 80% or greater)
This development is closest to Fire Station #2. Current reliability is 85% from this station and does
meet the targeted goal of 80% or greater.
3. Risk Identification Risk Factor (1=residential, 2=residential with hazards, 3=commercial,
4=commercial with hazards, 5=industrial)
This proposed commercial development has a risk factor of 2, in which current resources would be
adequate to supply service to this propose project. Hazards may be found once the development is
completed.
4. Accessibility Roadway Access, traffic, Radio Coverage
This project meets all required access, road widths and turnarounds as presented in the preliminary
plat. Any changes shall require fire department approval if any roadways or accesses are changed.
The cul-d-sacs shall be signed “No Parking Fire Lane” per appendix D of the 2018 IFC.
This project will require approval for secondary access through their property from West Ada School
District. If the approval is not signed and recorded by both parties, the project shall be limited to 30
lots until an approved secondary access is provided OR all units constructed in the subdivision shall
have fire sprinklers installed.

5. Specialty/Resource needs
a. Aerial device needed for development (more than 30’ in height)?
i. If yes, is one available within a 12 minute travel time goal
This proposed project will not require an aerial device. The closest truck company is 17 minutes
travel time (under ideal conditions) to the proposed development, and therefore the Fire Department
cannot meet this need in the required timeframe if a truck company is required. This fire station is
approximately 8.5 miles from the project
b. Other specialty needs (water rescue, hazmat, and technical rescue)?
i. If yes, is one available within a 5 minute travel time?
In the event of a hazmat event, there will need to be mutual aid required for the
development. In the event of a structure fire an additional truck company will be required. This
will require additional time delays as a second truck company is not available in the city.
6. Water Supply (list expectations)
Water supply for this proposed development requires 1500 gallons per minute for two hours.
(Approximate – see appendix B of the 2018 International Fire Code) The fire flow requirements may
be less if the building is fully sprinklered.
7. Other Comments
Project specific comments are listed below.
***All IFC code sections per 2018 IFC or as noted***
