Rialto requires erosion and sediment control Best Management Practices on all grading and construction sites under the California Building Code Appendix J (adopted in Title 15) and the city's grading ordinance. Projects disturbing 1 acre or more must obtain coverage under the State Construction General Permit (NPDES CAS000002) and implement a SWPPP. Wind-erosion (PM10) controls are also required by SCAQMD Rule 403 (Fugitive Dust) given Rialto's South Coast Air Basin location.
Erosion control in Rialto is governed by Rialto Municipal Code Title 15 (Buildings and Construction), which adopts the California Building Code including Appendix J (Grading), and by the city engineer's grading and drainage standards. All sites must implement BMPs from the California Stormwater Quality Association (CASQA) BMP Handbook - typical measures include silt fences, fiber rolls, gravel bag berms, stabilized construction entrances, hydroseeding, and inlet protection. Construction Activity ≥1 acre falls under the State Water Board's Construction General Permit (Order 2022-0057-DWQ) and must have a SWPPP prepared by a Qualified SWPPP Developer with risk-level-specific monitoring. SCAQMD Rule 403 applies citywide and requires fugitive dust controls (watering, soil binders, gravel pads, paved haul roads) on any active operation disturbing >0.1 acre or 100 cubic yards. Cal. Public Resources Code §21000 et seq. (CEQA) may require an erosion and sediment control plan in the project's mitigation measures. After grading, disturbed slopes must be permanently stabilized with vegetation or approved hardscape before final acceptance.
Failure to install or maintain erosion BMPs is a Title 15 violation triggering stop-work, daily fines under Rialto Code §1.16, and possible NPDES enforcement. State Water Code §13385 authorizes up to $10,000/day plus $10/gallon for sediment discharges to waters of the state. SCAQMD Rule 403 violations are enforced by South Coast AQMD with penalties typically $1,000-$25,000 per day per Cal. Health & Safety Code §42402.
