Local businesses and residents of all ages who want to participate in efforts to beautify Westchester High School and clean up the beach with Heal the Bay Sunday, May 7th, as part of the citywide Big Sunday annual day of service may join Los Angeles World Airports (LAWA) employees.

Los Angeles World Airports is the city agency that owns and operates Los Angeles International Airport (LAX) and three other Southern California airports.

Volunteers can mobilize with other service-minded individuals at more than 200 events at non-profit sites around Los Angeles.

Los Angeles Mayor Antonio Villariagosa is also joining the eighth annual Big Sunday Day of Service organizers to try to make the event the largest citywide volunteer day in America.

Information and registration for the two airport-area and other events are available by visiting the Web site, www.bigsunday.org

Los Angeles World Airports employees — under the banner of Team LAWA — are asking the airport community and others to join them for the volunteer effort at two LAX-area events:

n Westchester High School — Organizers are landscaping, painting and beautifying the school campus, 7400 Manchester Ave., from 1 p.m. to 4 p.m. For information, see event number 200 in the Web site above. Supplies and refreshments will be provided.

n Heal the Bay Beach Cleanup — Organizers are meeting at 6200 Pacific Playa Ave. LAX Big Sunday Volunteer Events are scheduled from 10 a.m. to noon, for a beach cleanup. For information, event number 112 on the Web site.

Volunteer registration for these two LAX-area events is also available by calling Judith Gorum, LAWA Big Sunday coordinator, at (310) 348-2525 or by e-mail to igorum@lawa.org

Other local area Big Sunday projects planned include those by the Mar Vista Community Council, the Westchester/Playa del Rey Neighborhood Council, the Grandview Elementary School PTA, and Friends of Walgrove Elementary.

Volunteers will plant trees and gardens, and paint and spruce up school grounds at Westchester High School, the James McBride School for disabled students, and Mar Vista, Grandview, and Walgrove Elementary Schools.

Big Sunday organizers say the event started in 1999. By 2005, the event had evolved into an annual citywide volunteer day involving more than 8,000 volunteers from more than 100 dif- ferent churches, synagogues, schools, offices and clubs helping nearly 150 nonprofit organizations.

Last fall, Villaraigosa conducted the first Citywide Day of Service, which attracted 7,500 volunteers who worked on projects at six public high schools in Los Angeles.

This year, Villaraigosa is supporting a combined effort to improve the city, organizers said.

The projects selected for this year’s Big Sunday event can be completed in one day, but organizers aim to inspire volunteers and organizations to continue the effort throughout the year.
