Technical assistance for better projects
WDFW offers a wide range of technical assistance that not only helps people implement habitat restoration projects, but also provides advice for designing fish-friendly stream crossings and residential and commercial/industrial development projects.
You can submit a general concept of their project for review through APPS at no cost – and without the need for SEPA documentation, final design, or other specifics. A WDFW Habitat Biologist will contact you to discuss project design and answer questions about the application process. WDFW recommends this approach for people who are uncertain about what a successful application might entail.
Native Plants – If your hydraulic project damages or destroys vegetation growing near the water, WDFW may require you to replace it as a condition of your HPA. The Washington Native Plant Society provides plants lists organized by counties and a list of specialty nurseries and seed suppliers that deal in native plants. This will help you find suitable plants for your project location.
