GLAESA stands for the Grand Ledge Area Emergency Services Authority.
GLAESA is an independent fire authority that was established in the 1990s. At that time, it included the City of Grand Ledge, Eagle Township, Oneida Township, and Watertown Township. Over time, Eagle and Watertown Townships formed their own department, now known as the Looking Glass Regional Fire Authority.
Today, GLAESA continues to serve the City of Grand Ledge and Oneida Townships by providing both fire protection and emergency medical (EMT) services.
