Farm Pond Restoration beforeFarm Pond Restoration after

The goal of this project was to enhance and rehabilitate the habitat value of a man-made farm pond by restoring the natural stream channel and riparian area.   The habitat function and suitability provided by the farm pond, a dammed stream channel, were low, containing one stratum of non-native reed canarygrass, and preventing fish passage by a non-passable culvert.   Riparian habitat was restored by draining the farm pond, enhancing the stream channel, and adding a fish-passable culvert.  Rehabilitation will continue over time as the mitigation area develops into mature, forested riparian habitat.


Project: State Route 14 Pedestrian Tunnel Crossing – Washougal, Washington

The City of Washougal’s State Route (SR) 14 Pedestrian Tunnel Crossing project is located in downtown Washougal, Washington and involves excavation of a 110- foot long pedestrian tunnel beneath the SR 14 embankment to connect pedestrians and bicyclists from downtown Washougal to Steamboat Landing Park. The tunnel will be 16-feet wide by 10-feet tall and will be excavated about 20 feet below the top of the SR 14 fill embankment. A plaza area will be constructed at the north entrance of the tunnel, and landscape and sidewalk improvements will occur along Pendleton Way between SR 14 and ‘A’ Street.
For this project, ELS conducted a wetland delineation, prepared a wetland delineation report, completed a No-effect Letter for Endangered Species Act compliance, and developed a wetland buffer  mitigation plan. In addition, ELS worked closely with the project engineer providing the environmental consultation and review to assist with permitting documents for this federally funded project, which included a JARPA, SEPA, and local agency Environmental Classification Summary.
Permitting involved coordination with Wallis Engineering, the City of Washougal Planning Department, the City of Washougal Parks Department, the US Army Corps of Engineers, the Washington Department of Fish and Wildlife, completed the Washington State Department of Transportation Local Agency Guidelines, and the Washington Department of Ecology. A critical areas permit, Shoreline Exemption and Hydraulic Permit Approval were obtained for the project.
