Bronx River Parkway Reservation
Why it's listed
Running about ten miles through Westchester County, the Bronx River Parkway Reservation combines a limited-access parkway, a cleaned and re-routed river, and a designed landscape of forests, meadows, lakes and footpaths. It was planned and built between 1906 and 1925, with Hermann Merkel directing the landscape design and Jay Downer, Leslie Holleran and Arthur Hayden handling engineering. Bridges of reinforced concrete faced in native granite were meant to blend into the scenery, and many were designed by architects such as Charles W. Stoughton and the firm of Delano & Aldrich. Two stone service stations in Crestwood were made to resemble small houses. The parkway was split into separate roadways in places to preserve trees, an idea later seen in highway medians. The Westchester County Center, an Art Deco auditorium completed around 1930, sits beside the parkway. The nominated section was kept intact, while the altered southern third was left out.
Significance in brief: The nomination presents the reservation as a landscape-designed parkway that kept the river valley's naturalistic character and retained a high degree of integrity. It notes innovations such as splitting the roadway into separate drives, an idea that later led to the highway median strip, and the use of stone-faced reinforced concrete bridges designed jointly by engineers and architects. The Westchester County Center, built within the reservation in 1927-1930, is also included.

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).
