Hanford's Environmental Rules: The Rules That Matter

Every city handles environmental rules a little differently. In Hanford, 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.

Flood Zones

Anyone building, filling, or altering land within Hanford's mapped special flood hazard areas must first obtain a floodplain development permit from the city under Municipal Code Section 15.52.130.

Key details: Permit required: Before any development in flood zone. Administered by: Community Development Director. Basis maps: FEMA FIS/FIRM, adopted by reference. Penalty: Misdemeanor, § 15.52.080.

Building or developing land in a special flood hazard area without a permit violates Section 15.52.080 and is a misdemeanor; the city council may take further lawful action to remedy the violation.

Stormwater Management

Hanford bans putting anything but rainwater into the storm drain system citywide, with fines that climb to $1,000 per violation and referral to the regional water board.

Key details: Enforced by: City Manager / enforcement agent. First offense fine: $100. Escalates to: $1,000 by 4th offense. Does not apply to: agricultural lands.

First violation: $100. Second: $200 plus notice to the regional water board. Third: $300. Fourth and beyond: $1,000 and referral for federal Clean Water Act penalties.

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

Erosion Control

Any grading in Hanford, California requires city approval under Hanford Municipal Code § 15.55.050, and applicants bear sole responsibility for keeping sediment off watercourses and neighboring land under § 15.55.210(D). Only excavations or fills of 50 cubic yards or less on gentle slopes are exempt. The building official or city engineer, in this Kings County seat, enforces the rule and can issue stop-work orders.

Key details: Governing chapter: Hanford Municipal Code Ch. 15.55, Grading Ordinance. Exempt threshold: 50 cubic yards or less, under 20% slope. Permit term: 180 days, extendable up to 1 additional year. Erosion control duty: Sole responsibility of applicant, § 15.55.210(D). Stormwater cross-reference: Ch. 13.10 Stormwater Quality Management ordinance.

Grading without approval, or work departing from approved plans, allows a stop-work order under § 15.55.300; anyone who continues after being served written notice "shall be guilty of an infraction." The violator must submit a remedy plan within 24 hours and complete corrective work at their own expense. The city may also suspend or revoke grading approval for cause under § 15.55.290, complete unfinished work itself and bill the owner under § 15.55.230, and require a new engineer's certification before work resumes.

Flood Elevation Requirements

New and substantially improved buildings in Hanford's flood hazard areas must have their lowest floor built at or above the base flood elevation, per Municipal Code Section 15.52.170.

Key details: A zone elevation: At or above base flood elevation. AO zone elevation: FIRM depth or 2 ft minimum. Mandatory freeboard: None (state recommends +1 ft). Certification: Registered engineer or surveyor.

Building below the required elevation in a flood hazard area violates Section 15.52.080 as a misdemeanor, and the owner may be denied a certificate of occupancy or face higher flood insurance rates until the deficiency is corrected.

The Bottom Line

Hanford's environmental rules rules are a mixed bag. Some areas are strict, others are relaxed, and the details matter. The best approach is to check the specific rule that applies to your situation rather than assuming Hanford is broadly strict or permissive.
