Showing ordinances that apply to Chiawuli Tak, AZ
Chiawuli Tak is an unincorporated community (population 48) in Pima County, Arizona. Because Chiawuli Tak is not an incorporated city, it does not have its own municipal code. Instead, Pima County ordinances apply directly to properties here. The grading & drainage rules below are the ones that govern your area.
Pima County requires grading permits for land disturbance in unincorporated areas and enforces strict drainage standards through the Regional Flood Control District. All new construction must demonstrate that post-development drainage does not increase runoff to adjacent properties. Washes and arroyos have mandatory setback buffers.
Pima County Development Services issues grading permits under the county grading ordinance and floodplain management code (Title 18). The Regional Flood Control District reviews drainage plans to ensure compliance with the Drainage Design Manual. Key requirements include maintaining predevelopment drainage patterns, retaining the first inch of stormwater on-site, and maintaining setbacks from regulatory floodways and erosion hazard zones. Wash setbacks range from 25 to 100 feet depending on wash classification (minor, major, or critical). Cut and fill operations exceeding specific thresholds require engineered plans stamped by an Arizona-registered professional engineer. The county also regulates watercourse modifications under the floodplain use permit process. Grading on slopes exceeding 15 percent triggers additional geotechnical review. Desert terrain grading must preserve natural drainage patterns and minimize scarring visible from public roadways.
Grading without a permit results in stop-work orders and penalties up to $300 per day. Altering drainage patterns that cause flooding to adjacent properties may result in enforcement action, restoration orders, and civil liability. Building within wash setbacks without a floodplain use permit is a code violation subject to structure removal.
