The NEM presents engineering policy clearly and completely so that NRCS engineering activities can be effectively and efficiently implemented. This link to the National Engineering Manual will take you to the NRCS e-Directives web site where you can view and/or download the NEM by sections and chapters. Once you have navigated to the e-Directives site, in the left side menu select "Manuals", then from the list on the right select Title 210 Engineering, and then select "National Engineering Manual".
