Buildable Lands Inventory (BLI)
In recent decades, the Portland Metropolitan region and the City of Portland experienced a steady increase in population. In 1980, the city’s population was about 368,000 residents. By 2011, the population has grown to nearly 585,000 residents. In another 25 years, how many people will live on Portland’s nearly 93,000 acres? Where in the city will people choose to live? What kinds of jobs will Portlanders have?
What is the BLI?
The Buildable Lands Inventory (BLI) helps us begin to understand what these forecasts might mean for Portland. Do our zoning and regulations allow for the development needed to accommodate the projected household and job growth? What are the factors that will shape where that change is most pronounced? To help answer this question, the City of Portland uses a computer model to project “development capacity.” Development capacity is defined as the likely number of new dwelling units or jobs that could be accommodated in the city under existing regulations, assuming existing infrastructure and physical constraints, and assuming the continuation of recent market trends. Development of this inventory is a state-mandated exercise, and part of Periodic Review Work Plan.
