Design solutions
We contracted with HWA GeoSciences to study the geologic aspects of the landslides. Then we hired Gray and Osborne as the City's design consultant, who proposed several design solutions. We looked closely at reliability, geotechnical concerns, maintenance, and cost. The location of the replacement sewer main minimizes ground disturbances and ties into an existing gravity-fed sewer line.
Affected owners
The City began working with property owners in 2013 to negotiate for the property rights to acquire a utility easement.
