South Frontenac Planner

South Frontenac Planner is a single-page planning map for the rural roads and trails of South Frontenac Township, Ontario. The base map is a 16-layer dark MapLibre stack served from locally-hosted vector tiles; the planner lets you draw waypoints and a route, attach a hazard (washout, downed tree, closure) to any segment, and persist the result for the session. An Info tab pulls in live Open-Meteo weather, an emergency-services directory, a curated difficulty rating, and a Reddit signal feed so a rider or driver can stage a trip without bouncing between tabs. Built on Next.js 16 + OpenNext and deployed as a Cloudflare Worker with a D1 backing store for routes and hazards.
