Planning and Engineering

Developing properties in Idaho 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 Idaho Department of Environmental Quality and NPDES permit requirements, including:

• Multi-Sector General Permit for Stormwater Discharges Associated with Industrial Activity (MSGP)
• General Permit for Discharges from Construction 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 Corrective Action requirements, 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 stormwater permit Corrective Action requirements.
