Fresno County
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.

Clovis FAQ
Do I need erosion controls for a small residential project?
Yes. Even sub-acre grading must use BMPs like silt fences and stabilized construction entrances. The SWPPP requirement only kicks in at 1 acre of disturbance.
When does Clovis require a SWPPP for construction?
When site disturbance reaches 1 acre or more, triggering coverage under the State Construction General Permit and a Notice of Intent filing with the State Water Board.
When is wet-season erosion control required in Clovis?
October 1 through April 30. During this window, Clovis Public Works requires enhanced BMPs (covers, fiber rolls, inlet protection) on active construction sites.
Reedley FAQ
When do I need an erosion control plan in Reedley?
All projects requiring a grading permit must include an erosion and sediment control plan with specific BMPs for each construction phase. Projects disturbing one acre or more also need a full SWPPP prepared by a Qualified SWPPP Developer under the state Construction General Permit.
What erosion control measures are typically required?
Common measures include silt fences, fiber rolls (straw wattles), gravel bag barriers, stabilized construction entrances, dust control watering, slope stabilization with erosion blankets, and stockpile covering. Enhanced controls are required during the October-April wet season.
What happens if sediment leaves my construction site?
Sediment discharge into streets or storm drains can result in city stop-work orders and code enforcement citations. The Central Valley Regional Water Quality Control Board may also pursue enforcement with administrative civil liability of up to $10,000 per day of violation.
