In built-up catchments, the development of the stormwater management strategy will need to address existing stormwater-related problems as well as providing the framework for sound practices in future development or re-development of the catchment. The fundamental factor underpinning the success of the stormwater management strategy is information on the current state of the catchment. This information primarily relates to:-
•causes and effects of degradation of the aquatic environment, including the severity of the effect and future "do-nothing" scenario;
•"land capability" in terms of suitability for the different types of management measures to address the problem.
In addition to examination of existing problems, data related to potential future activities will allow anticipated problems to be highlighted and thereby provide the basis for non-structural management measures to be formulated as part of the planning process.
