The City of Folsom has established requirements for controlling pollution from construction and post-construction development activities.

Erosion in construction areas can contribute excess sediments to the storm drainage system and local creeks. Other pollutants can also be generated at construction sites, including paints, solvents, dust, and concrete slurry.

City Requirements and Inspection

Most construction projects that involve grading, excavation, etc., are required to obtain a grading permit and comply with the provisions of the City's Grading Ordinance (Folsom Municipal Code 14.29).

An erosion and sediment control plan is required as part of the Improvement Plans. The city currently uses erosion and sediment control specifications and standards. You can obtain a copy from the Community Development Department.

Stormwater Inspections
The city’s stormwater inspector inspects construction projects for compliance with the city's stormwater regulations. The stormwater inspector conducts enforcement and responds to incidents involving illegal discharges to the storm drain system or local creeks and rivers.

State Requirements

Construction projects disturbing one acre or more also must obtain coverage under the State Water Resources Control Board's General Construction Stormwater Permit. Failure to obtain a general permit could result in notices of violation and significant fines.

The general construction permit requires a detailed stormwater pollution prevention plan (SWPPP) for your site. This plan must be available onsite for review by city or state inspectors upon request. The permit also requires you to conduct regular inspections of your best management practices before, after, and during storm events.

New Development and Redevelopment

New development and redevelopment projects offer a unique opportunity to design sites in a way that minimizes pollution and impacts to the environment. The city requires most of these projects to integrate stormwater quality treatment controls into the project design. The goal is to reduce pollutants in site runoff to the maximum extent practicable for the life of the project.

The city works closely with the Stormwater Quality Partnership to ensure that design standards are consistent from agency to agency, to the extent possible. The agencies have collaborated on the current Sacramento Region Stormwater Quality Design Manual effective July 2018.

Educational Materials for Construction Site Operators

The Sacramento Stormwater Quality Partnership has developed several documents and brochures to assist contractors with understanding their responsibilities in regards to stormwater quality. The brochures listed below can be found at https://www.beriverfriendly.net/documents/#construction.

• Controlling Runoff Pollution at Construction Sites
• Erosion and Sediment Control for Small Building Sites
• Concrete and Creeks Don't Mix
• Painting Without Polluting
