Chesapeake Bay BMP Verification Overview

The Chesapeake Bay Program partners have formally defined "best management practice" (BMP) verification as "the process through which agency partners ensure practices, treatments and technologies resulting in reductions of nitrogen, phosphorus and/or sediment pollutant loads are implemented and operating correctly." BMP verification can be viewed as a life cycle process that includes initial inspection, follow-up checks and evaluation of BMP performance. It is critical for Chesapeake Bay Program partners to verify that BMPs across the region are being implemented correctly and are, in fact, effectively reducing nutrient and sediment pollution as expected. It will help the partnership to measure success, locate areas in which partners need to adapt, and ensure that these conservation and technical practices are doing the job of protecting people's properties, lands, riparian habitats and local streams. More information on verification can be found on the Chesapeake Bay Program's website.

Virginia's BMP Verification Plan

DEQ received approval of Virginia's BMP Verification Program Plan from Chesapeake Bay Program Office (CBPO) in April 2019.

The Virginia Stormwater Management Handbook (Chapter 9, Appendix C) includes example checklists for BMP maintenance and inspection for urban stormwater BMPs. Example checklists for septic BMP maintenance and inspection are also available.

Virginia's BMP Warehouse

DEQ developed a web-based application, the BMP Warehouse, that enables local governments to report a wide variety of water quality BMPs to the agency. The BMP data submitted through the Warehouse is subsequently reported to the Chesapeake Bay Program.

The BMP Warehouse can be accessed at the following link:

DEQ held a webinar on August 27, 2020 to provide a comprehensive explanation of recent updates to the DEQ BMP Warehouse. The webinar was recorded and can be accessed via GoToMeeting (enter your name and email address when prompted to access the recording). The webinar presentation PowerPoint file is also available.

Virginia Statewide Land Cover Database

DEQ, in partnership with the Virginia Information Technologies Agency, completed the Virginia Statewide Land Cover Database, a 1-meter resolution classification of 2013-2015 imagery of the Commonwealth. Before development and release of the database, the latest available statewide land cover data in Virginia were from the 2011 National Land Cover Database, released at 30-meter resolution. The increased level of detail represented by the high resolution Virginia database significantly improves the Commonwealth’s capabilities for geographic analysis, management, and monitoring applications in biology, climate, disease analysis, land management, hydrology, and environmental planning, among other applications.
