Planning and Engineering

Developing properties in California requires climate-specific stormwater management solutions including Low Impact Development (LID) techniques to reduce flooding, recharge groundwater, and remove contaminants. We design stormwater infrastructure that protects our watersheds, becomes an asset to the site, and meets local and state design requirements.

NPDES Permits

MFA works closely with our clients to meet the California Stormwater Quality Association (CSQA) and State Water Resources Control Board NPDES permit requirements, including:

• General Permit for Storm Water Discharges Associated with Industrial Activities
• General Permit for Storm Water Discharges Associated with Construction and Land Disturbance Activities
• Phase I and Phase II Municipal Permit (MS4)
• Individual Permits

Whether you need a Stormwater Pollution Prevention Plan (SWPPP), recommendations for effective stormwater Best Management Practices (BMPs), or are facing a Level 1 or Level 2 Exeedance Response Action, we are here to help.

MFA also provides technical support and expert witness services for Clean Water Act lawsuits.

BMPs and Treatment

Effectively controlling pollution requires implementing a mix of operational, source control, and treatment Best Management Practices (BMPs) selected to fit your site constraints and contaminants.

MFA’s Professional Engineers have the expertise to recommend field-tested BMPs in response to California stormwater permit Level 1 and Level 2 Exceedance Response Actions.
