Reedley's Environmental Rules: The Rules That Matter

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

Stormwater Management

Reedley manages stormwater under Municipal Code Title 12, Chapter 2, Section 12-2-4, which establishes standards for the planning, engineering, administration, and construction of storm drainage systems within public streets, alleys, easements, and city property for the health, safety, and welfare of residents. The city participates in regional stormwater management programs coordinated through Fresno County and is subject to the Central Valley Regional Water Quality Control Board's National Pollutant Discharge Elimination System (NPDES) permit requirements. Construction projects disturbing one acre or more of soil must obtain coverage under the California State Water Resources Control Board's Construction General Permit and prepare a Stormwater Pollution Prevention Plan (SWPPP) detailing best management practices for pollution prevention during construction. New development projects must incorporate drainage infrastructure to manage increased runoff from impervious surfaces.

Key details: Storm Drainage Code: RMC Title 12, Ch. 2, Sec. 12-2-4. NPDES Trigger: 1+ acre of disturbance. Permit Required: Construction General Permit. SWPPP: Required with CGP. Public Works: (559) 637-4200.

Discharging pollutants including sediment, chemicals, waste materials, or contaminated water into the municipal storm drain system is prohibited and may result in enforcement action by the city and the Central Valley Regional Water Quality Control Board. Failure to obtain required NPDES permits for qualifying construction projects can result in state-imposed administrative civil liability of up to $10,000 per day of violation. Developers who fail to install required drainage infrastructure may have building permits withheld or certificates of occupancy denied.

Flood Zones

Reedley is bounded by the Kings River to the west, creating significant flood risk in portions of the city that fall within FEMA-mapped Special Flood Hazard Areas (Zones AE and A). The city regulates development in these flood hazard areas under Municipal Code Title 12, Chapter 1, which implements the National Flood Insurance Program (NFIP) requirements administered by FEMA. Properties in the Special Flood Hazard Area must elevate the lowest floor of new construction to or above the base flood elevation (BFE), and floodplain development permits are required before any construction, grading, or fill activity within mapped flood zones. The 2024 Fresno County Hazard Mitigation Plan identifies Kings River flooding as a primary hazard for Reedley, noting that low-lying areas including the Reedley Mobile Home Park are particularly flood-prone. High-water events in 2017 and 2023 prompted evacuations along the Kings River corridor through Reedley.

Key details: Flood Code: RMC Title 12, Chapter 1. River: Kings River (west boundary). FEMA Zones: Zone AE and Zone A. Elevation Required: Lowest floor at or above BFE. Upstream Dam: Pine Flat Dam (USACE).

Development in the Special Flood Hazard Area without a floodplain development permit violates RMC Title 12, Chapter 1 and federal NFIP requirements. Violations can result in denial of flood insurance claims, dramatically increased insurance premiums, code enforcement action with fines, and potential NFIP sanctions against the city that could affect all residents' access to flood insurance. Filling or obstructing regulatory floodways without permits is a serious violation that may require complete restoration of the floodway at the violator's expense.

This is not one of those rules that cities tend to ignore. Reedley actively enforces its flood zones requirements.

Grading & Drainage

Reedley regulates grading and drainage through the 2022 California Building Code grading provisions (Appendix J) adopted under RMC Title 9 and storm drainage requirements in Municipal Code Title 12, Chapter 2. Grading permits are required for projects involving excavation or fill exceeding the thresholds established by the California Building Code, generally 50 cubic yards of material. All finished grades must direct surface drainage away from building foundations with a minimum 2 percent slope for the first 10 feet, and drainage must be conveyed to approved public storm drainage facilities or other approved outlets. Development must not increase stormwater runoff onto adjacent private properties or concentrate flows in ways that cause erosion or flooding. The relatively flat terrain of the San Joaquin Valley makes proper site grading and drainage design especially critical in Reedley, as even minor grading errors can cause persistent ponding, foundation damage, and drainage disputes with neighboring properties.

Key details: Grading Permit Trigger: Over 50 cubic yards. Foundation Slope: 2% min for first 10 feet. Retaining Wall Permit: Over 4 feet height. Drainage Code: RMC Title 12, Ch. 2. Building Division: (559) 637-4200.

Grading without a permit is a building code violation subject to immediate stop-work orders and fines. Directing concentrated drainage onto neighboring properties can result in code enforcement action, required corrective grading at the violator's expense, and potential civil liability for property damage. Building retaining walls over 4 feet without a permit and engineered design is a serious structural safety violation. Failure to maintain proper drainage away from structures can void building code compliance and lead to foundation damage claims.

Erosion Control

Reedley requires erosion and sediment control measures for all construction and grading activities in compliance with the 2022 California Building Code grading provisions adopted under RMC Title 9 and stormwater quality regulations under Title 12. All projects requiring a grading permit must submit an erosion and sediment control plan demonstrating how soil disturbance will be managed during and after construction to prevent sediment from leaving the site. Projects disturbing one acre or more require a Stormwater Pollution Prevention Plan under the state Construction General Permit. The San Joaquin Valley climate, with its dry summers and concentrated winter rainfall between October and April, creates particular erosion risks when seasonal rains hit exposed construction soils. Enhanced erosion controls including stockpile covering, slope stabilization, and accelerated grading schedules are required during the wet season to protect water quality in the Kings River watershed.

Key details: Erosion Plan Required: With all grading permits. SWPPP Trigger: 1+ acre disturbance. Wet Season: October through April. State Fines: Up to $10,000/day. Building Division: (559) 637-4200.

Failure to implement required erosion controls during construction can result in immediate stop-work orders from the Building Division, code enforcement citations, and escalating fines until the site is brought into compliance. Sediment discharged into streets, storm drains, or waterways may trigger additional enforcement by the Central Valley Regional Water Quality Control Board with administrative civil liability of up to $10,000 per day of violation. Grading without a permit is a building code violation. Failure to maintain SWPPP BMPs during the rainy season is a common violation that can result in both city and state enforcement action.

The Bottom Line

Reedley'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 Reedley is broadly strict or permissive.
