Arbor Hill Historic District–Ten Broeck Triangle
Open space within the district include a few vacant lots and parking lots. Most are planned however, such as Van Rensselaer Park, the neighboring space around the church known as St. Joseph's park, and the large parcel at the district's northeast corner where the Ten Broeck Mansion and its gardens (and formerly carriage house) are located. Mature trees are abundant throughout. Topographically the district rises almost a hundred feet (30 m) from its eastern and southern edges to level terrain along North Swan between Second and Third. This reflects the ravines that existed there when Albany was first settled, later partially filled in to facilitate development, now the neighborhood of Sheridan Hollow, which separates Arbor Hill and the district from downtown Albany.
North Ann Arbor Street Historic District
The North Ann Arbor Street Historic District consists of 22 homes and 11 barns and carriage houses, located along a single block of Ann Arbor Street. The houses were constructed from the 1870s through the first part of the 20th century, and are primarily fine vernacular versions of Gothic Revival, Colonial Revival and Queen Anne architecture. The district also contains two Italianate homes and one Bungalow which have had substantial facade alterations, rendering them less historically significant, and two single-story ranch homes. Most of the homes are two-story structures faced with wood.
