Project Diamond-Middletown is a proposal for a warehouse and distribution building of about 113,400 square feet. It would sit on a 13-acre site inside the Middletown Auto Park, at 345 Auto Park Drive in Middletown, Delaware. For scale, that is roughly two Walmart-style supercenter floors' worth of space under one roof.
The county's July 2025 filing is a site plan. A site plan shows where the building, parking, truck access and drainage would go on the lot. The firms on the filing are PRDC - Middletown 2022, LLC and an engineering consultant.
No news coverage, meeting agendas, developer project page or announcement of a future tenant was found for this project. The explanation here rests on the county records alone. The site is part of an existing business park, which suggests the land is already set aside for commercial use.
What it could mean nearby
- Warehouse and distribution use usually brings truck and employee traffic. The county records give no traffic figures.
- The site is inside an established auto park, so the building would sit among other commercial neighbors. The records do not list nearby homes.
- The records do not say how many jobs the building would create or who would occupy it.
Where it stands
The latest county filing, a site plan, is dated July 2025. No approval or decision was found online. Site plans are normally reviewed by county and municipal staff and agencies, then approved or sent back for revisions, before building permits are issued.
