In addition to adding FDs from Paleto Bay, Sandy Shores, and maybe a Grapeseed, you could have Blaine County EMS, as is the case with some rural US counties, where each individual community is not large enough to warrant its own ambulance service, and a private company has not taken over the service area. Examples include Austin-Travis County EMS, Williamson County EMS (both TX), Door County EMS (WI), Greenville Co EMS (SC), and others.
If you really want to get in-depth, there might also be local Rescue Squads for the small communities (like Grapeseed). In this instance, Grapeseed may not have its own standalone FD, rather, it has a Rescue Squad and relies on neighboring departments for protection. An alternative to that would be having a multi-community FD, say something like the Sandy Shores-Grapeseed Community Fire Department or the Sandy Shores-Grapeseed Volunteer Fire Company. Just some food for thought. 😊
