Status of Post-Fire Remediation in
Areas Impacted by the North Hangar
Fire
1.After the North Hangar fire was declared “extinguished” on December
1, 2023, there have been a series of Santa Ana wind and rain events
during December 2023 and January 2024 that are causing fire-related
debris located on rooftops and in gutters to fall to the ground,
preventing CAC certification that properties previously mitigated
during the initial response remain clean.
2.Ground-level re-inspections in residential areas in proximity to the
North Hangar (e.g., Divisions “V,” and “C”) are finding more debris at
collection areas like gutters and drains and create exposure risk to
residents.
3.On January 26, 2024, EPA and South Coast AQMD recommended
that IEM conduct above-ground inspections of structures in the
impacted areas to evaluate the extent of above-ground debris and to
allow EPA and the Incident Response Team’s Environmental Health
Unit to evaluate the health and safety risks from future recontamination
by above-ground debris.
Scope of Above-
Ground Inspection
(Jan. 26-Feb. 1)
IEM and ATI performed above-ground
inspections of roofs, gutters and other
collection points at the following 13 locations:
In an effort to continue to provide additional
data points, visual Above-Ground Surfaces
(roofs, gutters, etc.) inspections occurred at the
following locations:
2 Neighborhoods within Division Charlie
Tustin Unified Schools Heritage, Legacy,
Beswick, Hillview, Sycamore, and Tustin
High/ Elementary
The Annex at Tustin Legacy & OCFA Fire
Stations 21, 26, 79
Columbus Square Community Center
Division Areas Visually Inspected For
Debris within Roof/Gutters
•Represented above are areas just North of Edinger inside of Division Charlie. From the ground -
level view, 13 homes were found with visible debris on roofs out of a 25 homes evaluated
(roughly 52% contained debris on rooftops).

Obstructions Found (Div. C)
Tustin Unified School Map
•This map is a depiction of all the schools
that reside within TUSD. The red and
yellow triangles are the 14 schools that we
previously found to have visual debris
located on the ground-level at the
beginning of the effort(green triangles
indicate no visual debris was found at that
time). This was used as a starting point for
rooftop data collection, beginning with
schools closest to the hangar to collect
additional data points.
•Red arrows indicate these 7 of the 14
schools contained debris at above ground
structures. At each location, an abatement
specialist sampled the roof top structures
and found every school examined to be
containing of 25-50 pieces of fire debris
and or suspected ACM . At this time, the
remaining schools listed as yellow are
being inspected in the same manner to
determine if they also contain fire debris
or suspected ACM on their
rooftops/gutters.

Columbus Square Community Center
•In order to collect more
data points, consent was
given by HOA President of
Columbus Square to
perform Remediation and
Inspection of the exterior
above-ground surfaces.
During this process,
remediation and
inspection took place and
over 50 pieces of
suspected ACM and fire
debris were removed
from the above ground
surfaces of the property.
•This process was
conducted by ATI under
the supervision and
direction of multiple CAC.

Photos Taken During Initial Inspection
**Photos depicted
here are of debris
that was found on
top of the roof or
in gutters and
then
photographed
from the ground.
During the Remediation and Inspection Process of Rooftops and Gutters
These photos show a
multitude of
different ways in
which we are able
to reach the
necessary heights
and locations above
ground level to
effectively
remediate and
inspect.
After the Remediation and Inspection Process of Rooftops and Gutters
Shown here are
all the after
photos when
ATI has
remediated and
the CAC has
finished their
inspection.
