TITLE
The Mayor and City Council shall discuss and take action to approve Amendment No. One to the Intergovernmental Agreement between the Arizona Department of Transportation and the City of Maricopa for roadway improvements along State Route 347 from north of State Route 238 to Maricopa City limits.
