A06_Drainage_Crossing.pdf

This file is a technical specification drawing for a typical drainage crossing design. The document is a detailed engineering schematic produced by the United States Department of the Interior, Bureau of Land Management, Pecos District Operations Office in Roswell, New Mexico, dated January 2022.

The drawing illustrates a four-strand barbed wire fence configuration designed to span drainage crossings. The design specifies 18" x 16" x 16" concrete installations on both sides of the drainage area, with 16" x 16" x 16" concrete on the right side. The diagram includes a wire spacing diagram detail and notes that attachment wires should be placed on the downstream side of the drainage crossing, with topography dictating the actual configuration. The specification requires additional gaps to be filled with the same wire used on the bottom strand, with wire terminating at each panel and single metal post to create "breakaway" sections within the drainage crossing. The drawing was designed by DSW, reviewed by R. Fox and B. Crawford, and approved by R. Porter, with a drawing number of 323116(DX) and scale noted as NTS (Not To Scale).
