Recorded Webinars

Do you want to create a plan for reducing nitrogen, phosphorus and sediment? These webinars are for you! Learn how to create a scenario and analyze the results.

Introduction to CAST and the data available

This webinar provides an introduction to CAST. It shows overall functions including viewing scenarios, loads and acres in maps, graphs and tabular formats. It shows how to view your current land use and which BMPs are credited in any year or scenario.


Editing BMPs

Learn the three ways to add and edit BMPs. Also review the three BMP report types, what they mean and how to use them.

Add and Edit BMPs

Creating Scenarios

Creating scenarios. 1 hour, 30 min.

Targeting reductions by location, load source and most effective, least expensive BMP

Targeting by location, load source and BMP. 1 hour, 15 min.


Using CAST to Develop an Environmental Control PLan for Nitrogen, Phosphorus, and Sediment

APA Virginia Chapter

This webinar demonstrates how to develop a nitrogen, phosphorus and sediment reduction plan using CAST. Plans are applicable to development of any water quality improvement plans including the Phase 3 Watershed Implementation Plan (WIP) for the Bay TMDL, local TMDLs, or MS4 permit action plans. The primary audience is local government planners who will use CAST to estimate the nitrogen, phosphorus and sediment loads resulting from selecting one or more BMPs to achieve their goals

CAST for Local Government Planners

This webinar provides an overview of how CAST can be used to answer some basic scoping questions, like how many BMPs in your community have been reported as implemented to the Bay Program, or what the land uses are. We then walk through how you can use CAST to develop a pollutant reduction plan (or similar implementation plan). A How-To Guide walks through the methods for answering several questions that were presented in the webinar. An example spreadsheet demonstrates how to apply CAST results to a geography that is not in CAST, like a township. The webinar was hosted by the Chesapeake Stormwater Network (CSN) as part of their webcast series.
