Jose Mier has always believed that Sun Valley, California, deserves attention not only for its hardworking businesses and industrial history, but also for the creative ideas shaping its future. One of the neighborhood’s most ambitious civic projects is the Rory M. Shaw Wetlands Park, a plan to transform a former construction-debris landfill into a place that combines flood protection, water conservation, wildlife habitat and much-needed public open space. For residents who know Sun Valley’s complicated relationship with stormwater, the project represents a remarkable attempt to make infrastructure serve the community in several ways at once.

From Strathern Pit to a community resource
The proposed park occupies a roughly 46-acre site near Strathern Street, Tujunga Avenue and Fair Avenue. The land’s previous life as an inert construction debris landfill is part of a broader Sun Valley story: the neighborhood’s gravel extraction and industrial operations left large disturbed sites that require careful planning for their next use. Rather than treat the property as simply vacant land, the Rory M. Shaw project envisions an engineered landscape that can address a practical local problem while providing a new public amenity.
The project is named for Rory M. Shaw, a civil engineer who worked for the City of Los Angeles and died in 2005 after floodwaters swept him into a sinkhole on Tujunga Avenue. The name connects the proposal directly to the people and public servants affected by Sun Valley’s flooding challenges. The park is a component of the larger Sun Valley Watershed Management Plan, a collaborative effort involving Los Angeles County, the City of Los Angeles and community stakeholders.
Why stormwater matters in Sun Valley
Rainfall that moves quickly across streets, roofs and industrial parcels can overwhelm drainage systems and create hazardous flooding. In a neighborhood where flood control has long been a concern, capturing runoff close to where it falls can help ease pressure on downstream channels. But stormwater is also a resource. Southern California’s water supply is challenged by drought cycles, and water that can be retained, treated and returned to the groundwater basin has value beyond the storm event itself.
County project descriptions explain that the wetlands park is intended to capture runoff from an upstream tributary area through a planned storm drain system. A detention pond would temporarily hold stormwater, while constructed wetlands would help improve water quality. Treated water is planned to be conveyed to infiltration basins at nearby Sun Valley Park for groundwater recharge. The project’s purpose is therefore not merely to move water away; it is to hold, treat and make better use of it.
How a constructed wetland can work
Constructed wetlands are designed systems that borrow some functions of natural wetlands. Water is directed through shallow areas planted with suitable vegetation, allowing processes involving plants, soil and microorganisms to help remove pollutants. The project’s engineering has to carefully balance storage, treatment, pumping, and safe operation during major storms. It is a sophisticated piece of public infrastructure, even if the eventual landscape is meant to feel welcoming and natural.
County fact sheets describe the planned park as a multi-benefit project, including water-quality improvements, native vegetation and habitat opportunities. The concept also includes recreational open space—about 15 acres in project descriptions—so that the site can contribute to neighborhood life rather than remain an inaccessible utility parcel. Details can evolve as design, funding and construction planning progress, so readers should consult the County’s project information for current plans.
More than a park: a neighborhood investment
Sun Valley residents need places to walk, gather and enjoy the outdoors, and public open space is especially meaningful in communities where industrial land uses occupy substantial portions of the landscape. The wetlands park’s recreational component is intended to add paths and green space while the water facilities operate behind the scenes. In this model, environmental engineering and everyday quality of life are not competing goals.
There are also long-term stewardship considerations. Wetland planting, water-quality controls, stormwater infrastructure and public areas all require maintenance. The site’s conversion from landfill use must be managed with the appropriate engineering and environmental safeguards. A successful project will depend not only on its initial construction but on responsible operations and care over time.
Project timeline and realistic expectations
Large watershed projects are complex, and the Rory M. Shaw Wetlands Park has been discussed and planned over many years. County and City approvals, design refinements, funding, construction sequencing and environmental review all influence when residents can expect the full park to open. Public documents have described the project as a substantial investment, and interim site improvements have been undertaken while the long-term effort continues. It is best to view the park as a major project in development rather than assume the proposed amenities are already open to visitors.
For the latest information, the Los Angeles County Department of Public Works maintains project materials, including descriptions and fact sheets. The County’s published plans are the most useful reference for understanding what is proposed and how the design may change.
A new chapter for Sun Valley
As a Sun Valley native and local businessman, I find projects like this compelling because they respond to real neighborhood needs while imagining a more balanced future. The wetlands park is not a simple beautification project. It is an effort to address flood risk, conserve water, improve habitat and create open space on land shaped by decades of industrial activity. If delivered and maintained as envisioned, it could become an important example of how a community can turn a challenging site into a shared asset.
Sun Valley’s story has always included industry, ingenuity and resilience. The Rory M. Shaw Wetlands Park proposal adds another chapter—one where infrastructure can be useful, ecological and community-minded at the same time.
