Route 9 Residential History

The Center for Historic Architecture and Design (CHAD) at the University of Delaware partnered with DelDOT to develop a historic context for residential subdivisions along the New Castle Avenue/Route 9 corridor, south of the City of Wilmington. The multi-phased project was designed to help understand the history related to settlement patterns in the area, specifically race-related settlement patterns and environmental justice concerns. CHAD researched each neighborhood in the study area, producing a background history and architectural analysis for each, collected oral history interviews, and provided a national and local context for post-World War II suburbanization, specifically related to inequitable housing policies and options for Black Americans. Five pre-war neighborhoods (Eden Park Gardens, Hamilton Park, Holloway Terrace, and Buttonwood, as well as Route 9 adjacent Minquadale) were also researched and discussed within the context of this study.
