Mayfield Environmental Solutions is an MBE/DBE General Contractor in Southern California with decades of experience in Stormwater Pollution Prevention Planning (SWPPP & NPDES) Services, Erosion and Runoff Mitigation, BMP Installations, Stormwater Management and Compliance, BMP Installs, Environmental Compliance, Environmental Site Assessments (ESA), Hydroseeding, Sandbag and Wattle/Compost/Geotextile installation, Sediment Traps/Retention and Detention Basins, and Waste-Water Pumping & Dewatering services. Let us do your Water Quality Testing for PFAS (“Forever Chemicals”), Lead, Radon Gas, and more.
We are the ONLY company in SoCal that can simultaneously offer certified SWPPP/NPDES/QSP/QISP inspections for Water Board Permitting, our own QSDs to design & certify SWPPPs, provide our own field labor to install BMPs and maintain GCP/IGP permitting, and miles of fire hose for Waste-Water Pumping and Hydroseeding. This includes work with Sediment Traps, Detention Basins, Retention Basins, and other BMPs. We also do Sewage Cleanups/Sewer work with proper vacuuming/pumping services, respirators, and H2S/hydrogen sulfide and oxygen monitoring protocols.
We are also experts in public works-related stormwater issues with CPMSMs on staff (Certified Professional in Municipal Stormwater Management) and for CALTRANS projects (with Water Pollution Control Plan Managers on staff).
We’ll be your comprehensive Water Board partners from start to finish. In California, ANY Construction over 1 square acre MUST apply for an NPDES Permit through the Water Board to maintain compliance with the Construction General Permit (CGP). This permit and a SWPPP (Stormwater Pollution Prevention Plan) must be written by a QSD (Qualified SWPPP Developer) like ours. Your site must be inspected regularly by a QSP Inspector like ours.
In California, ANY industry or manufacturer MUST apply for an NPDES Permit through the Water Board for Industrial General Permit (IGP) Compliance. Your site cannot certify itself! Your Industrial SWPPP must be written by a QSD like ours. Your site must be inspected regularly by a QISP (Industrial SWPPP) Inspector like ours.
Most QSDs/Developers disappear or don’t answer the phone after the job starts. We promise you our QSDs/QSPs will be available from start to finish.
We also have sediment, soil science, and erosion experts on staff, including the rare CPESC qualification (Certified Professional of Sediment and Erosion Control) and CISECs. We’ll help manage your local TMDLs, sediment load, pH, turbidity, and other key environmental risk factors.
We have the years of experience in Stormwater Management and MS4s (Municipal Separate Storm Sewer Systems) on multi-tiered projects, contaminated sites, and brownfields that you need to keep your development compliant with Water Board, city, and county regulations. Let us write your SWMP (Stormwater Management Plan).
We also have extensive Waste-Water Pumping Services & Dewatering and miles of fire hose to prevent unwanted discharge or SWPPP violations.
We are also experts in Green Stormwater Infrastructure (GSI) design and installation, being the only contractor in Southern California who can combine our landscape architecture licenses (C-27), soil management and erosion protection licenses, Water Board and stormwater licenses, and civil engineering licenses for your project.
We’ll help make your Jobsite, Development, Brownfield, or Property compliant with Industrial/Construction General Permit Regulations, as we’ve worked closely with QSPs (Qualified SWPPP Practitioners) and QSDs (Developers) for decades.
