Document Description
The project includes dam removal and bridge replacement on Milliken Creek, creek restoration actions, street drainage improvements, and construction of a bypass pipe. The existing dam on Milliken Creek at the Silverado golf course would be removed and replaced with a 20 ft wide by 122 ft long bridge. Creek restoration and enhancement activities would occur along approximately 600 ft of stream channel, extending from approximately 300 ft upstream of the existing dam. To address overland drainage issues in the Kaanapali Drive neighborhood, higher capacity drainage inlets will be installed on Kaanapali Dr. The project would also include the construction of a bypass pipe from the south end of the Silverado golf course to Kaanapali Dr and Hillcrest Dr intersection, and two new drainage inlets on Hillcrest Dr and Atlas Peak Rd to alleviate overland flooding.
