"We enjoy 40,000 daily visitors from Mexicali and I think we have to look at all the possibilities before making a decision," Renison said.
Grogan mentioned a population formula to divvy up the cash because El Centro and Calexico would capture the lion's share of revenue from a point of sale increase.
A point of sale tax would be meet with skepticism by Calexicans who think they were undercounted in the recent census and burned by the half-cent sales tax of 1992 that was to have provided medical care at Calexico Hospital, according to City Councilman Gilbert Grijalva.
If the tax isn't divided by population, Grogan suggested it could be similar to "the transit tax we have."
He said it is imperative for local municipalities to look into additional sources of revenue because everyone "wishes to have police and fire protection."
Grogan said El Centro is paying for 25 police vehicles with borrowed money.
He said if that pattern were to continue, the city could end up paying more than $700,000 a year for police and fire vehicles.
Grogan made a similar appeal before the county Board of Supervisors on Tuesday. He proposed the county join the task force and consider a quarter-cent sales tax increase countywide that could be used to increase police and fire protection services, as well as be used for capital improvements.
"This problem is absolutely not unique to the city of El Centro," he told the supervisors.
Grogan said the issue is a common one throughout the Valley. He asked county officials to think about joining the task force, how the money generated might be shared equitably and whether the tax should be a general one or a special one.
A general tax requires a simple majority at an election, while a special tax requires a two-thirds majority.
Grogan is expected to visit the other Valley's city councils with the same request.
