As urban areas expand, degraded lands robbed of natural resilience and biodiversity often lie in development’s path—presenting both challenges and opportunities. The Flewellen Creek Restoration project transforms a derelict 130-acre ranching ditch into a vibrant 3-mile ecosystem, anchoring the new 3,200-acre Cross Creek Ranch community.
Rooted in biomimicry and fluvial geomorphology, the design re-establishes natural creek dynamics. Reintroduced meanders double the creek’s length, creating a 450 to 600-foot-wide floodplain corridor, which shielded surrounding homes during Hurricane Harvey. A 50-acre polishing pond and water treatment facility feed the creek while filtering community irrigation water.
Indigenous vegetation replaces invasive species, establishing riparian forests, prairie meadows, and water-cleansing wetlands. Wildlife has returned in abundance, with native fish, turtles, and migratory birds thriving among strategically placed habitat structures. The endeavor yields impressive annual results: a 65% decrease in mowing expenses, an 81-ton reduction in fertilizer use, 4 million gallons of drinking water saved, and 184 tons of carbon sequestered per acre.
With 42% of residents living adjacent to the re-naturalized space, multi-use trails, boardwalks, and platforms invite exploration of the ecotones. The Arbor Park Sports Complex and disc golf course nestled amid the natural beauty further enhance daily life in this community. This multi-award-winning project is a paragon of restorative excellence, proving that nature and community can gracefully coexist. It demonstrates how conscientious designers can transform environmental challenges into opportunities, creating sustainable, resilient spaces that benefit both ecosystems and residents.
Next C
Next C Water City is a new, fully self-contained sustainable city planned for 500,000 residents. Water was central to the Next C planning concept, supplied by two adjacent rivers and monsoon rains. The city is a system of wetlands, rivers, lakes, and canals, cleansing the water from up-river communities and managing floods during the monsoon season. Working wi...
Woodbury
SWA provided planning services related to entitlement and land use for 1,400 acres of land in the City of Irvine, representing the last “flat land” development within the Irvine Ranch. Fundamental to the planning of Woodbury was the concept of a village “commons” with a mix of retail, residential, and office uses, which also includes a recreation c...
3Roots
A transformed mining site in Mira Mesa, 3Roots captures San Diego’s innovative spirit, drive, and natural beauty. SWA’s work began with the master plan, including 1,800 new homes, 160,000 square feet of commercial, retail, and office spaces, a five-acre mobility hub, and over 250 acres of parks and open space. The landscape blends the region’s mining her...
Magee Ranch
The project site is a beautiful 540-acre hillside ranch in suburban Contra Costa County, California. It was slated for development by the City of Danville as a clustered planned community. The development concept was to preserve the essential beauty of the ranch and to allow some 300 homes to be built with the least possible impact. The City’s Planning C...
