Riverside Legacy says its clean parcels are stuck — it can't develop and threatens a regulatory-taking lawsuit.

City Council - Feb 4, 2026
The city has paused new development applications in the proposed North Pyrite Master Plan area while it studies public health and safety risks tied to the Stringfellow Superfund site and other legacy contamination. The council was scheduled to consider a draft RFP for an environmental hazards and development safety evaluation — a key step before any development decisions there.
City Council - Jan 14, 2026
The council froze new development in the North Pyrite Master Plan Area because nobody knows whether the old Stringfellow acid pits Superfund site makes the canyon safe to build in. The EPA's final decision is years away; the moratorium buys time for a comprehensive environmental study.
