Riparian stream buffers are one tool that can be used to help prevent pollution from entering watersheds. They are strips of lands along waterways that are left undisturbed and preferably vegetated in order to reduce the amount of sediment, nutrients and other pollutants that travel downstream.

Stream buffer studyAlbemarle County staff asked the TJPDC to evaluate whether a program to waive property taxes on stream buffers would encourage conservation and increase water quality in the Chesapeake Bay. In 1998, the General Assembly passed enabling legislation allowing localities to do so. The study concluded that a program would benefit landowners with high-value and smaller properties. Large parcels would likely not see a benefit because of the high costs with planting vegetation as well as the fact that many of the parcels are already in land use taxation.
