A telephone survey will be conducted of McMinnville residents. The study will be used to collect data for a grant to make improvements to the local water system.“We need 550 surveys,” said Megan Farris, an economic development planner. “Please assure your citizens this survey is not a scam and it is critical in the process to secure grant funds.”The grant is a Community Development Block Grant (CDBG) the Upper Cumberland Develop-ment District is applying for at the end of this month.
