Buildable Lands Inventory (BLI)
The Buildable Lands Inventory (BLI) is an assessment of the City’s capacity to accommodate projected changes in housing and employment, including a series of maps. The maps will be used to identify land areas as either having full, diminished, or no capacity to accommodate additional housing units or additional jobs forecasted for the next 20 years. The maps represent possible constraints to achieving our forecasted increase in households and jobs.
Appendix C: Constraint Analysis
Maps and methodology used to identify and analyze constrained land. As adopted by City Council in October 2012.
Appendix B: Central City Development Capacity Study
Report analyzing the potential development capacity of land within the Central City. As adopted by City Council in October 2012.
