A scheduled job pulls the NPS designations API for the parks-managed monuments and a curated CSV for the BLM, USFS, and FWS units. Each row is normalized to a single schema with name, slug, agency, designation year, acreage, and feature list. The combined file becomes the source of truth.

Add a row to the roster with the proclamation year, the managing agency, the acreage, and the canonical agency URL. The cache refresh stamps a new live URL on the next render and the sitemap regenerator adds the URL within hours of the proclamation.

Yes. Carry a boundary_history array per monument, with each entry listing the year, the acreage at that time, and the proclamation reference. The page renders the history as a small table in the sidebar. Monuments like Bears Ears that changed boundaries get a meaningful history.

Some monuments are jointly managed by BLM and USFS or by NPS and a tribal coalition. The agency field holds an array and the page renders each agency as a separate badge with the appropriate link. The conditional access block falls back to the strictest applicable rule.

Yes. A second data source carries the active alerts and the page renders them in a small notice block above the static content. The alerts file refreshes hourly during fire season and daily otherwise, while the static roster refreshes weekly.

Yes. Carry an image_set field that points at a folder or a list of URLs. Most monument images are public domain through the managing agency, so the page renders a small gallery driven by a list mapping. Credit lines come from a per-image metadata file.

Carry a tribal_coalition field that lists the tribes party to a co-management agreement and a canonical URL to the cooperative agreement. The page renders the coalition as a small block under the agency badge. The history sidebar links to the formal agreement.

Carry a status_history array that documents proclamations that modified the monument, including the modifying president, the year, and a short description of the change. The page renders the history alongside the original designation.
