Resources and Tools

  • Virginia's Chesapeake Bay Phase III Watershed Implementation Plan Story Map - This story map was produced by DEQ to condense key information from the WIP to make it more accessible to the public.
  • WIP 101 in Virginia Fact Sheet - This fact sheet produced by DEQ and DCR provides a brief overview of the Chesapeake Bay clean up plan or TMDL.
  • Chesapeake Assessment and Scenario Tool (CAST) – This tool allows users to run the Chesapeake Bay model to evaluate and compare the nutrient and sediment loads resulting from various implementation scenarios. The tool includes scenarios for each annual progress year as well as historical planning scenarios like WIP II.
  • Model Source Data – This spreadsheet includes information about the model load sources, BMPs, and geographic references.
  • Chesapeake Bay Watershed Data Dashboard - This online tool was developed by the Chesapeake Bay Program and provides accessibility and visualization of data and technical information that can help guide water quality and watershed planning efforts.
  • BMP Cost Effectiveness Data - Knowing the BMPs that are most effective and have the lowest cost makes it possible to develop an effective plan. This spreadsheet includes the typical pounds of nitrogen, phosphorus, and sediment reduced for every BMP. Also provided are the cost of each BMP, and the cost per pound reduced. To determine the most cost effective BMPs, simply filter the table for your geographic area, then sort the table on the cost per pounds reduced for the targeted pollutant (we recommend using Nitrogen).    
  • Watershed Yields and Delivery Factors – Understanding where the highest loading areas and areas that deliver more of their load to the Bay can help geographically target implementation to maximize the reduction effect of a BMP.
    • Map (PDF)       
  • BMP Co-Benefits Matrix and fact sheets – Many BMPs have benefits beyond nutrient and sediment reductions.  A number of these co-benefits have been evaluated for each BMP.  This matrix can be used to characterize the additional benefits of a BMP strategy beyond nutrient and sediment reductions. Users can either select priority BMPs and see the co-benefits or choose co-benefits of interest and see which BMPs are most impactful.  Specific fact sheets have been developed for the following co-benefits:
  • Stream Corridor Land Cover Assessment- This assessment evaluates the land cover in the 150 foot corridor on each side of streams.  The tabular data sums the acres of Crop, Pasture, Developed, Roads and Natural land cover by County/City broken into 0-35 feet, 35-50 feet, 50-100 feet, and 100-150 corridors from the stream.  This dataset can be used to assess opportunities for establishing and/or expanding forest buffers and minimizing the impact of impervious surfaces in stream corridors.
  • Modeling the Chesapeake Bay Watershed fact sheet - This fact sheet produced by the Chesapeake Bay Program explains how models fit together and are used to help us understand the impact of pollution-reducing policies and practices at the regional and local level. 
  • Watershed Implementation Plan Planning Targets fact sheet - This fact sheet produced by the Chesapeake Bay Program describes how each watershed jurisdiction is assigned specific nitrogen and phosphorus reduction targets to meet Bay-wide reductions in pollution.
  • Quick Reference Guide for Best Management Practices - This guide produced by the Chesapeake Bay Program provides summarized profiles for each CBP-approved BMP in the Watershed Model.  Each reference sheet includes basic general information about a BMP, how it functions within the Watershed Model, what is needed for the BMP to be reported for annual progress submissions, as well as links to additional information to readers who want more detailed information about the practice.
  • Chesapeake Bay Phase III WIP Process webinar (recorded September 5, 2018) - This webinar was presented to provide training on how to update Best Management Practice (BMP) information into the Excel workbooks that were provided to Planning District Commissions, localities and other stakeholders involved with the Phase III WIP development process for the unregulated developed and urban lands sectors. Enter your name and email address, when prompted, to access the recording.
  • Virginia's Coastal Zone Locality PortalsEach locality portal is a gateway to current and historic shoreline management information, including interactive mapping tools, shoreline and tidal marsh inventory reports, sea level rise and flooding information, GIS data for downloading, and other locality-specific VIMS shoreline publications. The locality portals are updated as new shoreline and tidal marsh inventories are completed.
