Detroit’s neighborhoods grapple with a dual challenge: neglect and flooding. When the city stopped maintaining alleys in the late 1980s, responsibility shifted to residents. However, with limited resources and a declining population, many of these alleys fell into disrepair, becoming symbols of urban decay. This neglect is further compounded by the increasing frequency and intensity of severe storms, which have exposed the city's vulnerabilities in stormwater management, leading to regular flooding. To address these challenges, the "Alley Activation" project, launched in 2020 by a team of researchers at the UM-Dearborn in partnership with local residents and organizations, seeks to transform neglected alleys into vibrant greenways, rain gardens, and pollinator habitats. The project focuses on cleaning and greening alleys located in 2 neighborhoods namely Littlefield and McNichols. The activated alleys are bounded by Littlefield, Hartwell, McNichols and Outer Drive roads. These roads enclose an area of 141,436 square meters, located in the Bethune community and the Hubbell Puritan neighborhoods. Alley Activation involves clearing blocked alleyways and turning them into inviting, productive spaces that support sustainability goals. These revitalized alleys serve as a "green capillary system," contributing to the city's environmental, cultural, and social well-being. As these spaces are cleared, they offer a fresh opportunity to re-imagine their role and potential within the community. (1,2,3,4,5)

Principal problems in Functional Urban Area (FUA)

  • Climate-Related Hazards
  • Urban flooding (stormwater)
  • Extreme weather events (e.g. storms, hurricanes)
  • Land use and Socio-economic change
  • Unequal availability and access to public green spaces
  • Health, Well-being and Social cohesion
  • Poor community engagement
  • Insecurity in public spaces

Key priorities

Climate action (adaptation and/or mitigation), Social Justice and community

Focus

Creation of new green areas, Creation of any other green urban spaces, Transformation of previously derelict areas, Transformation of vacant land into green spaces, Knowledge creation and awareness raising, Educational and awareness raising programs

Project objectives

1. To utilize urban alleys in 2 neighborhoods as platforms for integrating rainwater harvesting on the background of recent flooding events that rendered the city's storm water management inefficient 2. To manage storm water runoff efficiently and increase resilience to climate change 3. To foster community-driven place-making initiatives that transform alleys into inviting, productive spaces and encourage local residents' participation in the design and maintenance of activated alleys. 4. To create pollinator gardens and other green infrastructure (greenways) within alleyways. 5. To reduce urban decay by revitalizing underutilized and neglected urban spaces. 6. To enhance neighborhood connectivity and safety through improved alley conditions. 7. To provide a small-scale proof-of-concept for sustainable alley activation that can be replicated in other neighborhoods and cities. 8. To conduct workshops and community events to educate residents about sustainability practices and technologies. (Ref.1, 2, 3)

Implementation activities

1. The project has been started in 2020, as part of a class at the University of Michigan. Students met online with residents and discussed plans to revitalize the alleys. 2. Activities in 2021 focused on allley cleanups (collaboration between students, faculty, and residents to clear and maintain alleys), neighborhoods mapping (analyzing garage roofs, gutters, flood risk, vacancy, and blight), installation of smart stormwater management systems (different rain barrel designs and a solar-powered "smart" rain barrel); pollinator plantings (permanent installation) in September 2021; community rain barrel workshops (Educational sessions on rainwater harvesting); 3. In 2022 these activities were planned and achieved: development of wind-solar microgrid (powers fence lights and a cooling mister); virtual reality (VR) alley designs (VR renditions to visualize and plan alley transformations); public showcases and events featuring art, music, and ecological design elements, such as during the Detroit Month of Design. (Ref.1,2,3)

Climate-focused activities

Climate change adaptation:

Main beneficiaries

  • Citizens or community groups
  • Marginalized groups: Disadvantaged ethnic or racial groups

Governance

Management set-up

  • Led by non-government actors

Type of initiating organisation

  • Researchers/university

Participatory approaches/ community involvement

  • Co-planning (e.g. stakeholder workshops, focus groups, participatory mapping)
  • Dissemination of information and education

  • Citizen monitoring and review

Details on the roles of the organisations involved in the project

The project was initiated by 3 professors at UM-Dearborn as part of a research grant offered by the University of Michigan. The professors provide technical expertise, conduct research, develop sustainable solutions, and assist with mapping and project implementation. Students of the university were also involved as they met online with residents and discussed plans to revitalize the alleys. The project received support from an NGO- DAVIS - Detroit Ain't Violent It's Safe that coordinates alley cleanups, community engagement, and the implementation of green infrastructure projects. Citizens: Local residents participate in the design, maintenance, and upkeep of the activated alleys, attend workshops, and engage in community events to ensure the success and sustainability of the project. (Ref. 1, 2,3)
