Description The Shoreline Management Act and all comprehensively updated Shoreline Master Programs (SMP) require that authorized activities result in no net loss (NNL) of shoreline ecological functions.

In this chapter of the Shoreline Permitting Manual, we consider how to review individual shoreline proposals for the careful and complete implementation of SMP NNL requirements. Ecology developed this guidance for local government practitioners who review shoreline proposals. Content covers:

Mitigation sequencing as the mechanism for achieving NNL

How applicants should document mitigation sequencing,

The use of project scenarios to reinforce concepts and best practices,

Practical guidance on reviewing mitigation plans, and

Tools and resources for improving compliance with mitigation sequencing and NNL requirements.

This chapter will help local practitioners to communicate requirements to applicants, identify deficiencies in site-specific documentation, and carefully and completely evaluate proposals for correct mitigation sequencing.

The scope of this guidance is limited. This chapter does not present a standard methodology for assessing shoreline functions, and it does not present prescriptive mitigation guidance.
The mission of the Department of Ecology is to protect, preserve, and enhance Washington’s environment. To help us meet that goal, please consider the environment before you print or request a copy.
