BLM OR Culverts Point Hub

CULVERTS_PUB_PT: This dataset defines attributes for major and minor culvert structures. According to BLM Manual 9100, a culvert is “a conduit or passageway, not classified as a bridge, under a road, trail, or other facility usually consisting of a round pipe, a pipe-arch, or an open or closed bottom box or arch.” Major culverts are defined as “a culvert having a clear opening of more than 35 square feet or multiple installations of culverts placed adjacent or contiguous as units and having a combined clear opening of more than 35 square feet.” This dataset only reflects the most current condition of the culvert as of the last visit and does not track the history of the culvert over time. Historic (removed) features may be retained in the parent Structures dataset.
