Decision process
To provide a process for determining the issues that need to be considered when managing stormwater during land development and when improving existing practices, the department has published Decision process for stormwater management in WA. The decision process also includes stormwater design criteria.
This decision process has been developed to help urban planners, local governments, state agencies, catchment management bodies and drainage service providers.
