Challenges
The project area contains sensitive riparian habitat in and around Dry Creek, a tributary of the Yuba River. As part of the scope of work, the installation of a clear water diversion of a perennial stream. The project is located within or near habitat for the following regulated species:
Western Pond Turtle (Actinemys marmorata)
Foothill Yellow-legged Frog (Rana boylii)
Central Valley Spring-run Chinook Salmon (Oncorhynchus tshawtscha)
California Central Valley Steelhead (Oncorhynchus mykiss)
Bats
Migratory Birds and Birds of Prey
An active Acorn Woodpecker nest was located in close proximity to the work site, requiring close monitoring to ensure that the birds were not disturbed by the nearby construction work.
Innovative Solutions
As this is a large-scale project encompassing large areas of sensitive habitat, careful monitoring and adaptive management approaches are necessary to protect biological resources throughout each phase of work. We developed and implemented several management plans for this project, including a Stormwater Pollution Prevention Plan, Natural Resources Protection Plan, and Exclusion Plan for bats and bridge-nesting birds. Daily site monitoring ensures that biological or environmental concerns are swiftly met with scientific knowledge and expertise.
