Linking Land Use and Water Quality

Toolkit > Mapping Resources

Maps provide a powerful tool for communities to identify and inventory the resources within their community and evaluate potential impacts from proposed activities. A community resource inventory – or CRI – combines natural, cultural, and economic data to provide a more comprehensive look of what makes up a community’s character, so the Community Resource Inventory (CRI) is the first step in the planning process.

This site will enable you to develop a CRI for your town by watershed using available statewide information. Understanding the watershed your community lies within is very important because how we use our land has a great influence on the quality of our water resources. A CRI is a list or atlas of the natural, cultural and economic resources in your community. Although the maps contained are appropriate for community-level planning, they are not suitable for site level assessment. However, having a good set of watershed inventory maps will help you and your community make decisions on the range of challenges – from open space preservation to economic development.


To conduct a CRI of your community or watershed choose your watershed at Build Your CRI.

Here you can page through a series of watershed maps showing important natural, cultural and economic resources, and access this information visually and as PDF document. This Inventory provides a foundation for sound, rational planning decisions.
