Red Clay Consolidated School District, New Castle DE County, PA

Cool Spring

Location Anchors

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.

Have you considered what happens to your renovation timeline when every exterior change — right down to a window replacement — requires a separate hearing before Wilmington’s Design Review and Preservation Commission, and what that process costs in time and professional fees before a single permit is issued?

A few specifics on this page are sourced from secondary aggregators or older filings. Confirm before relying:

• Approx Homes — No verified count of residential units within the ZIP 19805 portion of the Cool Spring neighborhood was found. The National Register nomination references 316 contributing buildings in the broader historic district, but this includes institutional and commercial structures, and spans both 19805 and 19806 ZIP codes. A precise residential unit count for the public records-defined area is not determinable from available sources.
• Interior Sqft Range Text — No verified square footage range for homes in this specific neighborhood was found in named sources. Zillow and public records listing descriptions show individual homes ranging roughly from 1,600 to 2,325 sq ft in nearby listings, but no authoritative aggregate range specific to Cool Spring 19805 was verifiable.
• Builder — The neighborhood developed organically between 1880 and the early 20th century; no single builder is documented. The City of Wilmington historic district records note development on Caesar A. Rodney’s subdivided estate but do not attribute construction to a named builder.
• Hoa Name — No HOA was found in public sales data or in New Castle County Community Association Portal records for this address area. Cool Spring is an unincorporated urban neighborhood inside the City of Wilmington; there is no maintenance corporation on record. The coolspringshoa.org domain found in search appears to relate to a different ‘Cool Springs’ community (likely in another state) and is not applicable here.
• Entity Type — Preset as ‘subdivision’ — overridden to ‘historic_district’ based on verified National Register listing (1983) and Wilmington City Historic District designation. Cool Spring is an organically developed urban neighborhood, not a platted subdivision with a single builder or HOA. See supersedes field.
• Era Band — Average year built of 1920 from the 33-year appreciation index is plausible given the documented development timeline (1880s–early 20th century core, with some 1940s–1960s infill per NeighborhoodScout). ‘Mixed’ is assigned because the neighborhood spans late Pre-1900 origins through Early 20th Century construction. No anomaly flagged — the 1920 average is consistent with the documented record.
