Virginia Stormwater BMP Clearinghouse The Virginia Stormwater BMP Clearinghouse is a centralized technical resource for Best Management Practices related to stormwater in Virginia. It supports implementation of water quality and water pollution control measures across municipal, county, and state programs, providing standardized designs, performance data, and maintenance guidance. The Clearinghouse integrates engineering, regulatory, and environmental information to assist practitioners, policymakers, and researchers working on Chesapeake Bay restoration and local watershed protection.

Overview

The Clearinghouse compiles engineering design standards, performance metrics, and maintenance protocols for structural and non-structural Best Management Practices applied to stormwater runoff in Virginia. It serves as a nexus among agencies such as the Virginia Department of Environmental Quality, local soil and water conservation districts, and regional planning commissions, while informing projects funded by programs like the Environmental Protection Agency and initiatives related to the Chesapeake Bay Program. The resource supports practitioners in cities including Richmond, Virginia, Virginia Beach, Virginia, and Alexandria, Virginia, and coordinates with academic institutions such as Virginia Tech and the University of Virginia.

History and Development

The Clearinghouse emerged amid increased regulatory focus on nonpoint source pollution following federal statutes including the Clean Water Act and state-level implementation by agencies such as the Virginia Department of Environmental Quality. Its development paralleled efforts by the Chesapeake Bay Program and collaborations among organizations like the Virginia Conservation Network, Virginia Association of Soil and Water Conservation Districts, and regional metropolitan planning organizations. Pilot projects and demonstration sites in localities such as Norfolk, Virginia and Hampton, Virginia informed early design manuals and helped standardize methods for calculating pollutant load reductions used in Total Maximum Daily Load planning.

Purpose and Functionality

The Clearinghouse provides standardized design specifications, performance verification, and maintenance checklists to support deployment of structural BMPs—such as bioretention, infiltration practices, and manufactured treatment devices—across urban, suburban, and rural contexts. It functions as a technical repository for municipalities, consulting engineers, and conservation districts implementing requirements from permits issued by entities like the Virginia Department of Environmental Quality and permitting programs administered under the National Pollutant Discharge Elimination System. The Clearinghouse also interfaces with modeling tools used by practitioners in stormwater management and watershed planning for tributaries to the Chesapeake Bay.

BMP Database and Technical Resources

The Clearinghouse maintains a searchable database of BMP categories, technical specifications, and performance data drawn from monitoring studies conducted by universities, U.S. Geological Survey projects, and state pilot programs. Resources include design templates, soil and hydrology guidance, and maintenance manuals for practices such as bioretention, permeable pavement, vegetated swales, and wet ponds, aligning with standards referenced by the Virginia Stormwater Management Program and guidance from the Environmental Protection Agency. The database cross-references case studies from municipalities like Chesapeake, Virginia and Lynchburg, Virginia, and integrates findings from research centers such as the Virginia Water Resources Research Center.

Implementation and Adoption in Virginia

Localities throughout Virginia adopt Clearinghouse-recommended BMPs through ordinances, capital improvement projects, and stormwater utility programs. Cities and counties incorporate designs into site plan review processes overseen by planning departments and public works agencies, while conservation districts and non-governmental organizations like the Chesapeake Bay Foundation facilitate demonstration projects and outreach. Adoption has influenced retrofit programs in older urban watersheds and new development standards in fast-growing jurisdictions including Prince William County, Virginia and Fairfax County, Virginia, often linked to funding mechanisms administered by state agencies and regional grant programs.

Regulation, Standards, and Guidance

The Clearinghouse’s materials are used to implement state regulatory frameworks, including Virginia’s stormwater control ordinances and permit conditions derived from the Clean Water Act and state statutes administered by the Virginia Department of Environmental Quality. Its standards support compliance with Total Maximum Daily Load allocations, municipal separate storm sewer system permits, and Chesapeake Bay nutrient reduction targets coordinated by the Chesapeake Bay Program and federal partners such as the Environmental Protection Agency. Technical guidance aligns with hydrologic and hydraulic methodologies promoted by academic centers and professional societies including the American Society of Civil Engineers.

Outreach, Training, and Support

The Clearinghouse conducts trainings, workshops, and webinars for municipal staff, consulting engineers, and maintenance crews, often in partnership with institutions such as Virginia Tech, the University of Virginia, and professional organizations like the Virginia Water Environment Association. Outreach includes demonstration projects, online tools, and user guides tailored to local governments, design professionals, and nonprofit partners such as the Nature Conservancy working on watershed restoration. These efforts aim to improve design quality, long‑term maintenance, and measurable water quality outcomes in tributaries to the Chesapeake Bay.
