1.0) Use of a Standard Design Approach The FBRB, as previously stated, requires that projects meet fish passage design criteria in Washington Administrative Code 220-660-190, the recommendations of the Water Crossing Design Guidelines (2013), and the expectations of the FBRB grant program. As such, Chapter 4 of the Water Crossing Design Guidelines provides guidance on bridge design and Chapter 3 provides guidance on the stream simulation design option. These design criteria provide guidance on how to apply a geomorphic approach for fish passage for all fish species, at all life stages. 2.0) Provide Analysis and Evaluation Engineering design and technical evaluation must be focused on achieving the project’s goals and objectives. In developing an application, RCO highly recommends sponsors consult Chapters 4 and 5 of the Stream Habitat Restoration Guidelines, which provide guidance on developing. 3.0) Water Crossing Design Guidelines The Water Crossing Design Guidelines is a WDFW document to help the water crossing owner and designer comply with Washington State law that protects fish. This document provides practical, real-world knowledge and techniques to improve the overall success of water crossings. These guidelines do not replace regulatory requirements, though they are designed in part as technical guidance supporting regulatory streamlining and grant application review for fish passage project applications. The FBRB highly recommends that project sponsors and designers review the Water Crossing Design Guidelines. Specifically, Chapter 1 discussing the geomorphic approach to designing fish passage corrections, Chapter 3 covering stream simulation culvert design, and Chapter 4 which provides bridge design criteria.
