|Coal Creek Drive Long Term Bank Protection Project Wins|
The American Public Works Association (APWA) Washington Chapter awarded the Coal Creek Drive Long Term Bank Protection project the 2019 Project of the Year Award for Emergency Less than $5M. The project team, led by Lewis County Public Works, included NHC (engineering, design, and construction support) and Steele Trucking (contractor). The project also received an award from the Timberline Community Association.
Coal Creek Drive ends at the Cowlitz River approximately six miles northeast of the town of Packwood, Washington. Since 2003, the river has eroded approximately 80–150 feet into the left bank, including the roadway, private property, and several structures. Lewis County Public Works retained NHC to design a long-term solution to stabilize the bank and prevent the Cowlitz River from eroding further into Coal Creek Drive and dozens of surrounding properties.
FEMA authorized funding for final design and construction in February of 2018. NHC immediately began the design so that a solution could be permitted and built in the summer of 2018, thereby preventing the loss of more homes in the coming flood season. The backbone of the design included a 600-foot long continuous log structure to arrest the active bank erosion, enhance aquatic habitat, and meet programmatic permitting requirements necessary to expedite project implementation. The project team collaborated on-site during construction to complete the project within the permitted timeframe and under budget.
Each of the following NHC staff played a key role in the success of this project. Katie Mozes managed the feasibility phase, the results of which were used to obtain FEMA funding for design and construction. She was also responsible for the interim bank protection that helped to safeguard homes while waiting for the long-term design to be funded. Jessica Lammers managed, designed, and was NHC's lead overseeing construction of the final bank protection. Andrew Nelson completed the geomorphic assessment and helped to inform design solutions. Erik Rowland was the Principal in Charge and Engineer of Record, involved in all phases of the project, including construction oversight.
