The overall aim of CulvertBC is to develop a set of procedures, criteria, and standards to define the technology of hydrologic/hydraulic design for forest road stream crossings in BC, and to make these available to practising professionals and technicians. This involves a review of methods and techniques presently being used, carefully selected research studies, wide consultation with practitioners, selection of the most suitable methods for design, and updating or, where appropriate, developing new methods, for:

• estimating the flow to be used for design in a particular situation
• developing a set of "best practices" for making design decisions on bridges and culverts, in different circumstances
• developing a set of best practices for ongoing maintenance and repair of culverts and bridges
