The fire started May 18 off Sandy Ave. in Simi Valley and became a regional concern because of wind, steep terrain and smoke. For Thousand Oaks residents, the practical takeaway was simple: the city was close enough to be named in the warning footprint, even if many households were never told to leave.

What changed by May 26

In Ventura County’s May 26 final routine update, the Sandy Fire was listed at 2,183 acres and 90% contained. The county said all evacuation warnings had been lifted, but firefighters were still doing mop-up work and would remain in the area over the next several days to patrol for hot spots.

That means the immediate public-safety phase had eased, but the burn area was still active enough to need crews, equipment and caution near dirt roads and fire lines.

Why smoke mattered in Thousand Oaks

Even residents outside the warning zones had a reason to pay attention. On May 20, the Ventura County Air Pollution Control District issued an air-quality watch because of smoke from the Sandy and Santa Rosa Island fires. The district said impacted cities may include Thousand Oaks, along with Newbury Park, Simi Valley, Moorpark, Camarillo, Oxnard and Ventura.

The air-quality watch was a smoke advisory, not an evacuation notice. It urged people to cut back on strenuous outdoor activity, keep windows closed if smoke was present, and pay closer attention if they or family members have heart or lung conditions.

For parents, commuters and business owners in Thousand Oaks, the main takeaway is that the city was directly touched by the Sandy Fire response, then cleared as the county lifted warnings. The fire was no longer in the fast-moving emergency phase by May 26, but officials still wanted people to stay alert around the burn area.
