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.

Some RestrictionsErosion 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.

Some RestrictionsFlood 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.

Heavy RestrictionsGrading & 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.
