Water Quality:  Select Areas to Enhance Actions

The “select areas” component of COAST provides CBP partners with tools to select areas to enhance management actions. Managers can use this information in conjunction with additional information on local water-quality problems to select areas to enhance actions that will restore and protect water quality in the Bay and local streams.

Version 1.0 of COAST provides information about nutrients related to several source sectors to help identify restoration areas, which is based on the SPARROW (SPAtially Referenced Regressions On Watershed attributes) models. Information for identifying areas for water-quality protection is based mostly on the CBP Resource Lands Assessment and other selected information.


The decision process for the select areas component is: SPARROW model resulsts graphic
The SPARROW model results allows users to delineate areas with higher yields of nitrogen and phosphorus, thereby focusing on areas that would most improve water quality (see the restoration area page for more information).
