Mr. Gorman provided professional assistance to Metro in the selection, hydraulic assessment and engineering design of candidate stream stabilization sites throughout 2.3 stream miles of the Upper Johnson Creek Natural Area. Floods resulting from storm events have caused erosion, bank scouring, and property damage in stream reaches lacking floodplain and riparian vegetation. He identified opportunities for restoration or enhancement of the preferred biological and physical habitat for salmonids within the assessment reach, evaluated stabilization merits of identified project sites, and identified groupings of stabilization work which provide project implementation efficiencies. Mr. Gorman provided construction oversight of project implementation.
