Captured April 27, 2009.The Natural Resource Inventory Update project is part of Portland's long-standing investment in conserving the natural resources in the City. Previous inventories produced by the City did not have access to GIS information relating to the location and type of natural resources within the City. The widespread availability of high-quality GIS data makes the development of a standardized, GIS-based model for determining the relative value of these resources possible.
