Storm surge protection systems have proven effective in protecting populations in
developed areas and can allow for development in otherwise potentially
flood-prone areas. Resultant intensification of land conversion can result in
large scale habitat fragmentation. Simultaneously, urbanized areas worldwide are
increasingly accumulating large amounts of vacant land, creating an unprecedented
opportunity to improve green space networks and natural systems. This article
describes creation of a regional growth framework that balances the need to
repurpose vacant lots with the provision of ecosystem services. The analysis
seeks to maximize the structural connectivity of the landscape by using high
ecological potential of vacant lands as a device for linking existing habitat
patches, wildlife conservation areas, wetlands, riparian corridors, and
small-scale green spaces. The research uses raster-based suitability models
generated in ArcGIS to determine development potential and ecological values of
vacant land parcels. Vacant lands having low development potential and high
ecological value are linked spatially to create ecological corridors among patch
areas using a least cost path connectivity model generated with Linkage Mapper
software. Results indicate that vacant land can connect existing ecological patch
and core areas with relatively minimal negative impact on development potential
while simultaneously enhancing provision of ecological services. The approach
provides a model for an ecological based solution to repurposing vacant urban
land.
