Redeveloping an Unused Site
Into a Community Asset

Award-Winning Project


The City of Oakdale needed to transform an abandoned mall site into a multi-use community asset.


An SEH team, serving as design engineer, worked collaboratively with the City and the private development team to develop a site that incorporates significant public amenities within a limited space. The resulting site includes a unique area that acts like a park when the weather is dry and a stormwater filtration area when there’s rain. It features a multi-celled treatment basin with decorative walls and spouts to direct rainwater through a meandering channel and a landscaped walking path with public seating areas.
