Helicopter traffic in the area near Angeles National Forest near San Francisquito Canyon will increase this week, as contractors for Southern California Edison will be using heavy-lift skycrane helicopters to finish tower assembly construction on the Tehachapi Renewable Transmission Project.

The County granted permits for the overhead activity that is expected to start as early as 5 a.m. from June 1 through June 10 (including Sunday, June 7).

According to a letter sent to residents in the area, Edison states that the heavy lift helicopters will begin moving tower sections in the early morning hours to avoid high wind speeds and warmer temperatures that could prevent the work from taking place.

From the letter: “SCE contractors will make every effort to minimize the amount of noise generated by construction activities. We recommend that during the ten day period you keep your windows closed and your pets inside, to the extent possible, which will also help minimize disruption.”

Questions about the construction or any complaints are being directed to Ana Fructo-Sanchez at (661) 257-8239, the project hotline at (877) 795-8787 or the SCE website at www.sce.com/tehachapi.
