The city of Camas sits next to the Columbia River about 20 miles east of Vancouver, Washington. The community of 20,000 was originally developed around a large paper mill, but in the past decade has seen a tremendous growth in high-tech, white-collar jobs and residents.

Northwest Friberg was a 20-foot wide 鈥渞ural-feeling鈥� roadway with no pedestrian facilities. The corridor had experienced increasing traffic, including vehicles associated with a nearby high school. It also was situation in an area that included wetlands and slow draining soils in an area that experiences an annual rainfall that is more than 150 percent of the national average.

As engineer for improvements for the area, Harper Houf Peterson Righellis Inc. worked with both the city of Camus and Clark County to create an elegant and functional solution that mitigated drainage and enhanced the value of undeveloped property on either side of the project area.聽 The project had to continue without impeding existing traffic flow during the proposed construction period of over two years. The design had to minimize impacts on existing right-of-way during the installation of new utility poles, 270 feet of waterline and nearly 4,200 feet of sanitary sewer.

The $4.3 million project was completed on time and within the original budget.

HHPR successfully delivered it work on the project meeting all required goals of the project, including adding a dedicated bike/pedestrian path featuring additional lighting and landscaping.

HHPR also met the Washington Department of Ecology’s requirement to lessen downstream impact by installing 47,000 cubic feet of stormwater detention.聽 In addition, 2,400 linear feet of 60-inch pipe was installed beneath the bike lane to receive and detain stormwater, filter it and slow its release into an adjacent ravine and nearby stream. The detainment system also protects nearby wetlands from periodic flooding from runoff.

The added bike lanes and paved pedestrian walkway also offer transportation alternative for students and staff at the nearby high school, encouraging them to walk and bike to school rather than drive.
