Redeveloping brownfield sites can be a costly proposition. In many situations, the private development and financial sectors are not able or willing to act on their own to ensure that the full economic potential of site reuse will be achieved. Critical funding gaps are, in fact, the primary deterrent to site and facility reuse. For decades, local governments have used or sponsored public finance mechanisms to stimulate economic activity in certain geographic areas or industries. Now, publicly driven economic development initiatives are reaching into new sectors and incorporating new concerns, such as environmental improvement. Local brownfield reuse strategies and financing techniques are rapidly evolving across the country.
