Greenway

Greenways: Linear corridors of public and private land that serve as the linkages between specifically identified natural resource-based or manmade features. They can be either land or water based and serve a variety of functions and benefits including recreation, transportation, community revitalization and economic development, natural resource conservation, environmental protection, wildlife habitat and migration and education. These corridors often follow old railways, canals, ridge tops, rivers and stream valleys.
