Local communities are gearing up for annual Fourth of July celebrations and events, including fireworks in Marina del Rey and Santa Monica, a live music event on the Marina Peninsula and a parade in Westchester.

MARINA FIREWORKS — A traditional fireworks display will be launched from Marina del Rey’s main channel starting at 9 p.m. Independence Day, Wednesday, July 4th. The fireworks will last about 20 minutes.

The show is presented by the Los Angeles County Department of Beaches and Harbors, and the fireworks will be orchestrated by Zambelli Pyrotechnics, a company that originated about 100 years ago in Italy.

County officials recommend viewing the fireworks from Burton Chace Park, 13650 Mindanao Way, Marina del Rey; or Fisherman’s Village, 13755 Fiji Way, Marina del Rey. Admission is free, but parking in county lots ranges from $5 to $8.

The fireworks are choreographed to “patriotic music,” which will be broadcast in sync with the display on the Loyola Marymount University radio station KXLU 88.9 FM. The music will be relayed over loudspeakers in Burton Chace Park.

In addition, the Marina del Rey WaterBus service will operate from 11 a.m. to midnight Wednesday, July 4th, offering an alternative way to travel around the Marina, as a number of streets in the Marina will be closed temporarily throughout the day. (See story on page 10.) The WaterBus fare is $1.
