Valley City Hall, they hammered out innovative solutions to the area's
development challenges which would go on to transform municipal redevelopment
and funding processes.
Engineering services expanded throughout California,
Nevada and Arizona. Willdan Engineering participated in some of the Southwest's
most significant projects, including California's statewide structural bridge

award-winning flood control projects.
