Compton City Councilwoman Yvonne Arceneaux and West Basin Municipal Water District Director Gloria D. Gray were seated Tuesday as the newest members of the Metropolitan Water District board.

Arceneaux replaces Isadore Hall III, who had represented Compton on Metropolitan’s board from February 2004 until his election to the California Assembly last fall.

Gray succeeds Willard H. Murray Jr., who had served on the Metropolitan board since January 1999.

Metropolitan board Chairman Timothy F. Brick named Arceneaux to the board’s Engineering and Capital Programs, Legal and Human Resources and Real Property and Asset Management committees.

He selected Gray to serve on the Communications and Legislation and Water Planning and Stewardship committees.

Elected to the Compton City Council in 1993, Arceneaux is serving her fourth council term. In 2002, she retired after 26 years with the Compton Unified School District.

Arceneaux chairs the Compton Creek Task Force, a partnership of city, county, state and federal government agencies and nonprofit organizations established by then-Rep. Juanita Millender-McDonald in December 2001 to address the creek’s environmental issues.

Gray was elected to West Basin’s Board of Directors in 2006, representing the cities and communities of Inglewood, South Ladera Heights, Lennox, Athens, Howard and Ross-Sexton.

The Inglewood resident is the first African American woman to be elected to the West Basin Board of Directors in its 60-year history. During her first year on the board, Gray was presented with the “2007 Water Person of the Year’’ award by the Water Replenishment District of Southern California for her commitment to conservation and building reliable water supplies for our communities.

Gray actively supports West Basin’s legislative agenda to bring state and federal funding into the district to keep the cost of water reasonable for the communities West Basin serves, according to the MWD.

Gray, who retired from the Los Angeles County Department of Health Services as an associate hospital administrator, is a member of the Los Angeles County Hospital and Health Care Delivery Commission and former Inglewood Unified School District board president.

In March, Los Angeles County Supervisor Mark Ridley-Thomas appointed Gray to a water quality community task force, as part of the county’s Clean Water, Clean Beaches initiative to address pollution in local rivers, lakes, bays, beaches and coastal waters.

The Metropolitan Water District of Southern California is a cooperative of 26 cities and water agencies serving 19 million people in six counties.
