Idaho Engineering References


Welcome to the Idaho Natural Resources Conservation Service (NRCS) engineering technical resources download site.

This site has standard drawings, technical references, and computer programs that field offices for NRCS in Idaho use to assist private landowners, conservation districts and local government entities to plan and design conservation practices.  All technical resources are available to the general public, and while all have been examined for technical adequacy, the responsibility for proper application remains with the user.
