A pair of Measure W-funded projects are expected to bring new greenery to Wilmington while also treating stormwater pollution in the Dominguez Channel and the Los Angeles harbor area, per an initial study published recently by the City of Los Angeles.

The Wilmington Greening Infrastructure Projects, an initiative from the City of Los Angeles Bureaus of Engineering and Sanitation, will be split into two phases.

The first component, the Wilmington Neighborhood Greening project, will involve the installation of a stormwater diversion system at the Wilmington Recreation Center. The 8.4-acre park at 325 N. Neptune Avenue , would see a new retention basin built at the southwest corner of the park below the existing baseball fields with associated stormwater diversion and treatment infrastructure. Plans also call for adding new trees and planters along Bay View Avenue and West C Streets, as well as the addition of new lighting, bleachers, dugout benches, batting cages, and fencing to the baseball fields. Other areas of the park would see the addition of drinking fountains, a picnic areas, permeable pavement, and new vegetation.

Gruen Associates and Geosyntec are part of the project team for the Neighborhood Greening project, per plans included with the study.

Phase two, the Wilmington-Anaheim Green Infrastructure Corridor Project, calls for new stormwater diversion and treatment infrastructure beneath several streets in the Wilmington Area, adjacent to the Wilmington Recreation Center. At ground level, plans call for approximately 1,500 linear feet of new bioswales, 50 new street trees, and the resurfacing of two alleyways with permeable pavement.

In total the two projects are expected to capture 97 acre feet per year of wet-weather stormwater from an overall 238 acre area. Work at the Wilmington Recreation Center would occur over 25 months, starting in early 2026 and concluding in early 2028, while the Wilmington-Anaheim project would be built over 21 months between Summer 2027 and early 2029.

According to a city website, the estimated cost of the project is just shy of $12.3 million.
