A prototyping model that estimates the full cost of alternative land-use patterns. SCALDS estimates monetary and non-monetary costs associated with urban land development. It builds on three areas of research ­ least-cost planning, which has been used by utilities for a number of years; full cost of travel studies; and cost of service/cost of sprawl research. The full cost accounting framework uses average cost data, derived from a variety of national studies, as the default values for the calculation of costs.
