Quirks & notes
- RCDC = Rancho Cucamonga Development Code — Title 17 reorganized 2010-12 (Ord. 855); significant 2024 amendment cycle for 6th-cycle Housing Element compliance.
- Three platform 403 mirrors: qcode.us, ecode360.com, cityofrc-ca.elaws.us — all Cloudflare-gated against scripted WebFetch (same CA pattern as bakersfield.municipal.codes).
- Specific Plan hybrid coverage: ~25-30% of city land area governed by Specific Plans (Etiwanda SP, Etiwanda Heights NCP, Industrial Area SP / Empire Lakes Sub-Area 18 / The Resort, Foothill Boulevard SP) per Chapter 17.38.
- Etiwanda Heights Neighborhood and Conservation Plan (EHNCP) is 4,393 acres total (790 Neighborhood + 3,603 Rural/Conservation) — uses 'regulating zones and subzones' (form-based-adjacent) per Table 17.38.070-1.
- Camino Predera Overlay (CP) is unusual — covers exactly 38 specific parcels with optional development standards in lieu of base L zone.
- Equestrian Overlay (E) preserves equine/bovine/cleft-hoofed animal-keeping rights — concentrated in historic Alta Loma equestrian district north of 19th St.
- Cucamonga Valley Water District (CVWD) administers wellhead protection within RC limits — NOT codified as a Title 17 overlay (administrative, not zoning).
- Rancho Cucamonga is on Metrolink San Bernardino Line, NOT LA Metro letter rail — no obsolete A/L/E line references. Planned Brightline West HSR terminus at Cucamonga Station strengthens AB 2097 transit-buffer applicability.
