The Development Infrastructure Impact Model (DIIM) is a financial impact model that evaluates the costs and revenues resulting from the development of new neighbourhoods.

The goal is to help understand how changes in key drivers affect the long-term financial outlook of the development.

The tool helps to inform decision-makers, by tying together land use, infrastructure and service costs, demographics, and revenue information into one complete package. This allows for scenario analysis and the exploration of the consequences of alternative design.
