The general principles and procedures which should be observed and followed by those proposing to undertake canal estate projects are set out in the associated guidelines. The general policy principles and guidelines also apply to other projects incorporating artificial waterways, such as harbours and marinas. In these cases, however, the detailed zoning provisions may vary.

Canal estates and artificial waterways projects affect the interests of many authorities and agencies and so it is important that the recommended procedures are followed as closely as possible to achieve the best and quickest results from the system through which proposals must pass before approvals are obtained.
