Hamilton County Mayor Jim Coppinger on Wednesday sent a letter to Chattanooga Mayor Ron Littlefield asking the city to help it come up with a plan to fund four agencies funded under the tax agreement.
The agreement will expire in May and city officials say they have no intention of renewing it before then.
Coppinger's letter seeks to work out funding for the Chattanooga-Hamilton County Health Department, Erlanger Health Systems, Emergency Services and the Regional Planning Agency.
"The first three of these agencies were jointly supported before the expiring agreement was established and we ask that they continue to be jointly supported by our respective governments," Coppinger wrote.
Coppinger asked the city to respond to the letter by April 15.
