Clean Water Optimization Tool



The Clean Water Optimization Tool is a planning tool for Maryland communities to develop more cost-effective strategies for reducing stormwater pollution to meet nutrient and sediment reduction goals. Although the impetus for the Tool was the Chesapeake Bay TMDL, it can also be used to address local impairments for nutrients and sediment.

The Tool was developed by the Center for Watershed Protection with funding from the Town Creek Foundation and it allows the user to optimize BMP selection based on cost-effectiveness for a particular pollutant, determine the practical limits of implementation, and evaluate progress towards water quality goals. The Tool also includes the most up-to-date crediting procedures approved by the Chesapeake Bay Program and allows the user to evaluate the impact of practices that have not yet been approved.

Free downloads of the Tool and associated resources are provided below. To provide feedback, ask questions or report problems with the Tool, contact Reid Christianson at The Clean Water Optimization Tool is owned by the Center for Watershed Protection and was developed for educational, research, and non-profit purposes. Use of the Tool, its components or derivations for profit is strictly prohibited.



This spreadsheet can be used for tracking BMP implementation and reporting to the Maryland Department of the Environment, and the compiled data can be entered into the Tool to track progress towards TMDL targets.

Eastern Shore Case Studies: The Center tested out the Tool with four Eastern Shore counties, and showed a reduction in costs of 25%- 67% over the original Watershed Implementation Plan strategies.
