Abstract: The Winooski Hydroelectric Company of Montpelier, Vermont is conducting the reconstruction of Dam #8 on the Winooski River in East Montpelier, Vermont. Unprecedented eminent domain proceedings were subsequently initiated against the utility for the taking of the project while detail site investigations of the condition of the concrete intake works and spillway were conducted by an engineering firm on behalf of the utility. As a result of these activities, two major economic and developmental adjustments occurred: The Court found in favor of the Winooski Hydroelectric Company and set payment at substantially less than the original asking price. Detailed site investigation showed that the condition of the existing intake works was worse than expected. It was then determined that a different project development scheme which would eliminate the downstream penstock and powerhouse in favor of an elongated excavated tailrace and integral powerhouse would be more cost effective.
