The county's seven incorporated cities will be required to pay 50 percent of the expenses of the Local Agency Formation Commission beginning July 1 under a new state law.
Assembly Bill 2838 requires the county and cities split the cost.
Under the formula used to split the costs among the cities, El Centro's share of an estimated $50,300 LAFCO budget for 1999-2000 is $14,109.84, or 56.1 percent of the cities' share.
"LAFCO performs an invaluable function for the county and the cities," said El Centro Mayor Cheryl Walker. "We recognize the value of that contribution."
The city of Brawley is responsible for $3,521.03, or 14 percent of the estimated costs.
Brawley Mayor Wayne Johnson said he is unfamiliar with the new law and could not comment.
The other cities' shares are, Calexico, $4,587.31, or 18.24 percent; Imperial, $1,101.44, or 4.38 percent; Holtville, $852.58, or 3.39 percent; Calipatria, $532.54, or 2.12 percent; and Westmorland, $445.25, or 1.77 percent.
