From KERA News:
People who call 911 expect help to arrive fast. But it can take a while for emergency services to reach rural areas in Collin County where fire departments already have limited resources — and might not be able to help some people in distress.
Blue Ridge has a population of about 1,000 people. It’s less than two square miles in size. But its volunteer fire department serves 68 square miles of unincorporated land in Collin County in addition to its own residents. That’s mostly rural areas that aren’t annexed into any cities or towns. Blue Ridge, which is about 20 miles northeast of McKinney, answers 911 calls in unincorporated Collin County as far as the Fannin and Hunt County borders.
