Should local parks prioritize historic preservation over creating new facilities for visitors and staff?

Tohono Chul is set to implement a new 15-year master plan aimed at sustaining the garden and expanding its reach. Leadership will present the strategy during an open house event on October 22, 2026, following a meeting with the Oro Valley Town Council.

Why it matters

The master plan serves as a roadmap to preserve historic buildings and protect native Sonoran landscapes over the next decade and a half. These updates are intended to provide improved facilities for staff and volunteers while ensuring the site remains a sustainable resource.

The master plan spans a 15-year duration and incorporates feedback from 800 visitors, members, and partners. An open house for the project is scheduled from 5 p.m. to 7 p.m. on October 22.
