Challenges we addressed in this study

Modifying the methodology provided by Center for Watershed Protection -- which focuses primarily on percent of impervious surface -- to make it more applicable to our rural setting.

Engaging landowner input to the study.

Getting better resolution data than is available from some commonly used sources such as USGS.

Identifying parameters for which available data can be applied systematically across all subwatersheds.

How to apply data that are not consistent across all subwatersheds, such as water quality data?

What are appropriate weights for the various parameters in the model?

Estimating future changes in land use.

Developing a scoring system that is easily understood.
