The Lathrop-Manteca Fire District will soon be adding nine firefighters to its ranks to staff a rescue unit that will help provide services to the sprawling district. And initially it will end up costing them virtually nothing. For the second time in the last 10 years, the district has been named the recipient of the staffing for adequate fire and emergency response – or SAFER – grant that will provide $2.1 million worth of personnel funding to help the district transition into full-time staffing for the River Islands fire station now under construction.
