About
Cool Spring is a late-19th-century urban neighborhood on Wilmington’s west side, formally recognized in 1983 when the Cool Spring Park Historic District was listed on the National Register of Historic Places. The district developed primarily between 1885 and 1900 on the former 23-acre estate of Caesar A. Rodney — U.S. Attorney General under President Jefferson — and its growth was catalyzed by construction of the 37-million-gallon Cool Spring Reservoir in the early 1870s. The housing stock is predominantly two- and three-story semi-detached brick dwellings in Queen Anne, Italianate, Colonial Revival, and Second Empire styles, with 316 contributing buildings recognized in the National Register nomination. Exterior alterations to properties within the City Historic District require approval from Wilmington’s Design Review and Preservation Commission, a regulatory layer that affects renovation budgets and timelines buyers should factor into their due diligence.

What Makes This Distinct
Because Cool Spring sits within both a National Register Historic District and a Wilmington City Historic District overlay zone, any building permit for exterior modifications — including window replacements, door changes, and rear-yard landscaping — must receive Design Review and Preservation Commission (DRPC) approval before work can begin; unapproved work is subject to financial penalties under city code. Buyers who plan significant renovations should budget for the DRPC review process and consult the city’s Land Use and Planning department at 800 N. French Street before closing.
