Directing urban development to the right places.pdf

Abstract: The provision of new housing for a growing population is a challenge that many cities and regions all over the world are confronted with. The design and management of new housing development is plex task given it needs to be socially, environmentally and economically sustainable. This paper describes a new method that helps spatially direct new housing development to minimise impact on water quality. Currently, the model modates for the pollutants total nitrogen (TN), total phosphorus (TP) and suspended sediments (TSS), but can be extended. The method is based on mathematical programming linked with multi-criteria analysis, and kinematic wave equations. It utilises GIS to underpin multiple spatial constraints on where housing development can take place, and to provide an effective means of visually analysing the impacts of land development scenarios produced by the model. We demonstrate the method using a case study for Hornsby Shire Council, New South Wales, Australia. With water quality and waterway health being a major issue in any urban development the proposed methodology has wide applications beyond the current study area.Landscape and Urban Planning 113 (2013) 62–77
