Suitability analysis is a geographic-based process to determine the appropriateness of a given area for a particular use. Such an analysis is conducted by systematic and multi-factor data process with a result highlighted differently from low to high suitability. Arc GIS Spatial Analyst is an application toolset in Arc GIS, ESRI, and it provides spatial analysis tools to perform integrated raster analysis or suitability study. In this plan, spatial analysis is applied to make a suitability map showing the most suitable area for new development on Tonawanda Island. The data in this project include vector data, raster data and aerial. Vector data includes land property parcel data, streets data, city line, soil data, and river boundary data. Raster data includes Digital Elevation Model (DEM) file and tree canopy raster data. The data sources are USGS Seamless Data Warehouse and New York State GIS Clearinghouse.
Site Redevelopment Principle:
- Build on Suitable Area: The future land uses and parcels should be decided by the suitability for redevelopment. The sites highlighted by the green dash line are the suitable area for redevelopment.
- Proper Scale of New Buildings: The new buildings should keep similar scale with buildings in the downtown area to keep a sense of water-town of the North Tonawanda. Big-box buildings are not preferred.
- Create Better Street Connectivity: Future redevelopment should have a grid street network or loops to provide better street connectivity on the island.
- Landscape and Open Space: Existing underutilized grassland with trees should be preserved as open space with a multi-use trail for walking, jogging, and biking. New tree lines along the Taylor Driveway create a better sense of access to the waterfront and the main street on the island.
