The Oliver Alleyway Green Alley Project was developed to transform a pedestrian corridor in Hyattsville, Maryland, into a safer, more accessible, and environmentally friendly community connection between residential areas and Baltimore Avenue (Route 1). The project incorporates green infrastructure and other improvements to better manage stormwater while improving the alley as a neighborhood connection.

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. 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)

With funding from the City of Hyattsville, the LID Center advanced the project through design, developing plans for phased implementation of the alley improvements. The design incorporates permeable pavement, bioretention, native landscaping, pedestrian-scale lighting, and other improvements to create a more accessible community connection while reducing stormwater runoff and improving water quality. The LID Center completed its design work in February 2026, providing the City with plans that can be implemented in phases as funding becomes available.
