Below are more of the proposition O and related green infrastructure projects that provide a water quality and water supply benefit. Many provide other benefits such as habitat restoration, recreation, aesthetics, urban heat island reduction, and potentially community revitalization benefits as well. 1. Wilmington Drain Multi-Use Project 1.1 This project will enhance Wilmington Drain via a multi-step approach including stormwater screening and treatment, 1.2 Enhanced public access, 1.3 Bank stabilization, and 1.4 Native vegetation restoration. 1.5 Stormwater quality will be improved using netting systems that will trap trash and debris and utilize natural materials and well-planned landscaping features, avoiding the need for destructive clearing of the channel. 1.6 The project will create a public park to provide recreational opportunities for the surrounding disadvantaged communities. 1.7 The park will include multiple amenities including a fenced off-leash dog area and 1.8 Decomposed granite trails with educational signage will provide learning and passive recreational opportunities. 1.9 The site furnishings will include tree-shaded benches, drinking fountains, picnic tables that offer visible seating and safe gathering spaces. 1.10 Permanent restrooms are proposed to provide an alternative to the observed use of the channel for such needs. 1.11 Costs of approximately $21 million.
