Fontana's Environmental Rules: The Rules That Matter

Every city handles environmental rules a little differently. In Fontana, California, there are 4 distinct rules that residents and property owners should be aware of. Some are stricter than what neighboring cities enforce, and others are more relaxed. Here is what you need to know.

Erosion Control

Fontana requires erosion and sediment-control BMPs on graded sites. The California Construction General Permit and FMC grading code require silt fences and stabilized entrances during the Oct-Apr wet season.

Key details: State Permit: Construction General Permit. Trigger: 1+ acre disturbed. Wet Season: Oct 1-Apr 30. Grading Trigger: 50+ cubic yards. Daily Fine: Up to $500+ city.

Fontana issues stop-work orders and administrative citations up to $500 per day for erosion-control failures. State Water Board penalties under the CGP can reach $10,000 per day or more per violation.

Compared to other cities, Fontana takes a harder line on erosion control. The enforcement and penalty structure reflects that.

Stormwater Management

Fontana enforces the MS4 stormwater permit from the Santa Ana RWQCB under the federal Clean Water Act. FMC rules prohibit non-stormwater discharges to storm drains and require construction BMPs.

Key details: Governing Permit: Santa Ana RWQCB MS4. Federal Law: Clean Water Act / NPDES. SWPPP Trigger: 1+ acre construction. LID: Priority development projects. Federal Fine Max: $64,618 per day.

Fontana may issue administrative citations of $100, $200, and $500 per violation and seek injunctive relief. Federal Clean Water Act penalties can reach $64,618 per day per violation under 33 USC 1319.

This is not one of those rules that cities tend to ignore. Fontana actively enforces its stormwater management requirements.

Grading & Drainage

Fontana grading and drainage follow FMC Title 15 and California Building Code Appendix J. Cut or fill over 50 cubic yards or hillside sites require a Building and Safety grading permit.

Key details: Governing Code: FMC Title 15 + CBC App J. Permit Trigger: 50+ cubic yards. Soils Report: 3 ft cut/fill or more. Min Drainage Slope: 2% for 5 ft from foundation. Drainage Rerouting: Civil Code 3479 liability.

Unpermitted grading triggers stop-work, double-fee permitting, and potential removal and restoration. Drainage discharges onto a neighbor expose the owner to civil claims. Administrative citations under FMC Title 1 start at $100 and escalate.

This is not one of those rules that cities tend to ignore. Fontana actively enforces its grading & drainage requirements.

Flood Zones

Fontana participates in the National Flood Insurance Program using FEMA Flood Insurance Rate Maps. Areas near San Sevaine and Etiwanda Creek channels fall within Zone A and Zone AE.

Key details: Program: NFIP (FEMA). Key Zones: A, AE near channels. Freeboard: 1 ft above BFE typical. Rule Threshold: 50% substantial improvement. Insurance: Required in SFHA.

Unpermitted development in a SFHA can trigger stop-work, removal, and loss of NFIP community good-standing. Individual owners may lose NFIP insurance eligibility. FMC Title 15 violations carry administrative fines.

If you are a homeowner, renter, or business owner in Fontana, take the time to understand these requirements before they become a problem.
