Purpose and Scope

The purpose of this Standard is to establish a list of standard descriptive elements for use in erosion- and sediment-control plan development. These elements consist of mapping symbols, keys, modifiers, and corresponding nomenclature. By improving consistency across plans, this Standard should facilitate the use and review of such plans by contractors and other professionals.

This Standard will not restrict creation of additional descriptive elements as required for practices not included here.

This Standard does not imply that these practices are suitable for erosion or sediment control in any or all applications. The descriptive elements are intended only to facilitate communications.

All descriptive elements must be legible. The sizes of the elements are at the discretion of the user.

Information within this Standard is not intended to be used in lieu of other construction information and details. Symbols should be used to indicate spatial placement of a practice (as presently done). A legend should always be used in conjunction with the symbols. Keys may be used in documents, as a textual alternative to the mapping symbol. Modifiers may be used on both symbols and keys to clarify their intended mitigating functions for each usage.
