A person must obtain a hydraulic project approval (HPA) prior to commencing any construction project that will use, divert, obstruct, or change the natural flow or bed of any of the salt or fresh waters of the state. Hydraulic project approvals are issued by the Department of Fish and Wildlife (WDFW) to ensure the proper protection of fish life. To receive an HPA, the applicant must provide certain information to the WDFW. This information includes general plans for the overall project and complete plans for the proper protection of fish life. The WDFW may impose proportionate conditions on a permit.
Other permitting requirements may also apply to certain projects located along waterways, including, for example, the requirement to obtain a shoreline substantial development permit issued under the Shoreline Management Act.
If a person wishes to replace residential marine shoreline stabilization or armoring, that person must use the least impacting, technically feasible bank protection alternative for the protection of fish life. Unless the Department of Fish and Wildlife (WDFW) provides an exemption depending on the scale and nature of the project, a person that wishes to replace residential marine shoreline stabilization or armoring must conduct a site assessment to consider the least impactful alternatives.
A person should propose a hard armor technique only after considering site characteristics such as the threat to major improvements, wave energy, and other factors in an analysis of alternatives.
A hierarchy of stabilization techniques is created, in descending order of preference:
