Possible Opportunities for Implementation of Vegetated Buffers, 100 ft
2024-06-30
Chesapeake Conservancy
vector digital data
This dataset identifies vegetated buffer opportunity areas (VBOAs) for the implementation of forest and grass buffer practices to reduce sediment and nutrient runoff in the Chesapeake Bay Watershed. These opportunity areas were generated using hi-resolution land use (2017/18) and hydrography datasets (2024 edition, derived from lidar data ranging from 2008-2021) produced by Chesapeake Conservancy.
This dataset is intended to facilitate watershed planning and implementation of vegetated buffers throughout the Chesapeake Bay Watershed by identifying areas within 35ft and 100ft of estimated edge of mapped streams with land use types that may be converted into vegetated buffers. The edge of the stream is derived from a combination of mean channel width and observed surface water. Land uses that are included in potential opportunity areas include: tree canopy over turf grass, turf grass, transitional barren, suspended succession barren, suspended succession herbaceous, harvested forest barren, harvested forest herbaceous, natural succession barren, natural succession herbaceous, cropland barren, cropland herbaceous, pasture/hay barren, pasture/hay herbaceous, orchard/vineyard barren, orchard/vineyard herbaceous, solar field barren, and solar field herbaceous. The dataset was developed by Chesapeake Conservancy as part of a 6-year Cooperative Agreement between Chesapeake Conservancy and the U.S. Environmental Protection Agency (EPA) to provide geospatial support to the Chesapeake Bay Program Office.

These data were developed as a reference resource for watershed planning and are not prescriptive layers that could replace site-specific engineering/project designs. Results from this mapping tool should be ground-truthed using local knowledge through stakeholder and landowner participation. The opportunity area datasets do not account for already existing BMPs, and may under- or overestimate the total area available for new implementation. The 2017/2018 land use/land cover data from which these BMP opportunity datasets were derived may contain errors that affect BMP opportunity area reported. Chesapeake Conservancy does not guarantee the accuracy of suggested practice locations. Local knowledge and planning expertise is required to apply the datasets in an appropriate manner and to ensure restoration projects will result in significant water quality benefits on-the-ground.
