The Oliver Alleyway Green Alley Project aims to transform a 500-foot pedestrian corridor into a safe, accessible, and environmentally friendly community connection between residential areas and Baltimore Avenue (Route 1) in Hyattsville, Maryland. Once complete, the alley’s existing asphalt surface will be replaced with permeable pavement. Bioretention features and native landscaping will also be installed to reduce stormwater runoff, improve water quality, and enhance the alley’s appearance and usability.

Phase 1: Planning (2021–2022)

The initial planning phase was supported by a Chesapeake Bay Trust Prince George’s County Stormwater Stewardship Grant in partnership with Prince George’s County. During this phase, the City of Hyattsville and the LID Center developed the project concept, identified site opportunities and constraints, and engaged nearby residents from Hyattsville and Riverdale Park to establish community design priorities.

Phase 2: Design (2024–2025)

The current design phase, funded by the City of Hyattsville, is focused on developing a phased, construction-ready plan set and specifications to move the project to construction. The LID Center is leading the design process, while the City of Hyattsville continues to coordinate community engagement to ensure that residents and neighbors remain informed and involved.

Phase 3: Construction (Anticipated 2026)

The construction phase will implement the design to create a functional green alley that manages stormwater on-site and provides a more attractive and accessible pedestrian connection. Improvements will include permeable paving, bioretention planters, native plantings, and pedestrian-scale lighting. Once completed, the alley will serve as a model for sustainable infrastructure and community-based green design within the City of Hyattsville and the surrounding region.
