I am working on a study which requires the use of GIS to begin to identify both vacant and under utilized parcels within 1/2 mile of train and bus stations. GIS parcel and zoning data are being used as a first cut to narrow down the universe of parcels focusing in on those parcels that are vacant and undertutilized. The identifying vacant parcels based on available parcel attribute data is readily obtainable. However trying to create a definition for underutilized parcels has been frustrating. The GIS is just the first step in a process to identify then inventory vacant and underutilized parcels that could benefit from transit oriented development planning. There will be extensive outreach to municipal officials, community groups business organizations and residents to identify parcels that would benefit from intensive TOD planning. A small number of sites will be selected and then master plan and zoning amendments, prototype access standards, transit and access improvements, educational and promotional materialsand sketch plans will be developed for each site through a public participation process along with a charette.
Any person or group that can provide guidance in identifying a rule of thumb using GIS parcel attribute data to determine a scale to identify underutilized parcels located near transit or train stations is much appreciated. I have 11 train stations and seveal bus routes to analyze using county GIS parcel and tax data. However developing a query to use with our ARCview GIS to identify potentially underutilized lots has not been successful to date.
I am sure that some research has been undertaken and published somewhere that addresses this exact point however I have been unsuccessful at finding infromation that will allow me to develop a rough tool or some type of bench mark to to narrow the number of lots to be investigated as being undertutilized and or vacant.
