The GIS tool and its documentation, “ICLUS v1.2 GIS Tools and User's Manual: ArcGIS Tools and Datasets for Modeling US Housing Density” enables users to run a spatial allocation model (Spatially Explicit Regional Growth Model, SERGoM) with the population projections developed for the U.S. In 2009, EPA released a report describing the development of nationwide housing-density and impervious surface scenarios. The ICLUS (Integrated Climate and Land Use Scenarios) project uses demographic modeling as the basis for the housing-density scenarios. These scenarios are broadly consistent with global-scale, peer-reviewed storylines of population growth and economic development, which are used by climate change modelers to develop projections of future climate. Population at the county scale is placed as housing on the landscape using SERGoM v3 (Spatially Explicit Regional Growth Model).
The Geographic Information System (GIS) tool allows users to:
- replace the ICLUS projected population values to reflect different growth rate assumptions;
- customize housing density patterns by altering household size and travel time assumptions;
- summarize patterns by region, watershed, county, or NLCD 2001 land cover classes;
- reclassify housing density into classes different than those already provided; and
- generate a map of estimated impervious surface based on a housing density map.
