Beaver Historic District
Why it's listed
Beaver is a historic district on the Ohio River in Beaver County, Pennsylvania, laid out in 1792 by deputy surveyor Daniel Leet under an 1791 act of the Pennsylvania General Assembly. Its grid of streets surrounds a set of public squares at the core and at each corner of the original plat, a feature the nomination describes as distinctive to the town. The district holds Italianate commercial blocks, Queen Anne and Colonial Revival houses, churches built between 1890 and 1930, two railroad depots, and a 1933 Art Deco courthouse on Agnew Square. Its historic role as a county seat and a residential community, rather than an industrial one, shaped its layout and building stock. The site of the eighteenth-century Fort McIntosh lies within the district and is considered likely to hold significant archaeological remains.

What listing means for this property
This is a historic district. Buildings within its boundary are either contributing (they add to the district's significance) or non-contributing. Owners of contributing income-producing buildings can claim the 20% federal rehabilitation tax credit; homeowners should look at state credits. National Register districts impose no design review by themselves; a local historic district ordinance, if one exists, does (the difference explained).
