<br /> 24. BRIEF DESCRIPTION OF PROJECT AND RELEVANCE TO THIS CONTRACT (Include scope, size, and cost)
<br /> The County of Hawaii's Hakalau Stream Bridge (Bridge No. 29-3)was built in 1930 as a stream crossing for the Old Mamalahoa Highway.
<br /> Over time, Hakalau Stream severely eroded the historic bridge's northern abutment creating a large scour cavity beneath the footing. On
<br /> February 9, 2017, Mayor Harry Kim issued an emergency proclamation recognizing the"imminent threat of the bridge suddenly collapsing"
<br /> and "the need for government agencies and/or representatives from the private sector to mobilize and provide immediate services". The
<br /> extent of the scour compromised the bridge's stability, and ultimately affected its ability to safely sustain vehicle loads. The County closed
<br /> the bridge to prevent the possibility of property damage and/or bodily injury.
<br /> Challenges of this project involved developing an appropriate fix for a historic bridge in the midst of U.S. Fish and Wildlife and National
<br /> Marine Fisheries concerns for numerous Section 7-protected species, including the Hawaiian Hawk, nesting waterbirds, and water quality
<br /> impacts to essential fish habitat downstream. The project team developed a feasibility study and coordinated with resource agencies to
<br /> identify the preferred solution. Relying heavily on
<br /> national research, the team developed and _ a 5
