Two small fires broke out in La Mesa Wednesday afternoon south of Mission Trails Regional Park.

The two fires started just after 1:30 p.m. along Jackson Drive, a busy route through the residential community.

One fire was reported at Jackson and Hemingway Drive. A second fire was less than a half of a mile away near Jackson and Tuxedo Road.

When crews with the San Diego Fire-Rescue Department arrived, they found brush burning uphill and threatening structures, according to a spokesperson.

The fuel was light to medium.

Fire officials called for air support from the Cal Fire Ramona Air Base but canceled the request around a half hour later.

A helicopter made at least one water drop on the fire that was burning in a wooded area between homes.

One acre was damaged in one fire and a half acre was damaged in the second fire, an SDFD spokesperson said.

No structures were damaged and no one was injured.

Officials have not determined what caused the fire.
