On our Facebook group for HLE residents, we often mention the 403 service area and the fact that it includes many subdivisions and even non-subdivisions property. Polk County has assigned certain areas of the county to fire department service areas. We are the smallest area in Polk County TX, but it still covers multiple subdivisions. Here are some images that explain it all better than I can (click images, twice, to enlarge):
