I propose a conceptual design for nonstructural stormwater treatment using vegetated swales for a contaminated industrial site informally called Piers 92, 94 and the Backlands, on the southern waterfront in San Francisco. The site was created from landfill and remains in active industrial uses. The Port of San Francisco plans to redevelop the site with an access road and several more industrial lots, and needs to provide treatment for the ensuing contaminated runoff. To design the appropriate dimensions of the swales, I determined drainage areas, assigned runoff coefficients, calculated runoff volumes, and proposed sizing and planting pallet for vegetated swales. I also discuss the maintenance needs and suggest methods for monitoring the treatment performance.
