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.
Federal Hill, Baltimore
The neighborhood is named for the prominent hill that is easily viewed from the Inner Harbor area, to which the neighborhood forms the physical south boundary. The hillside is a lush green and serves as a community park. The neighborhood occupies the northwestern part of a peninsula that extends along two branches of the Patapsco River—the Northwest Branch (ending at the Inner Harbor) and the Middle Branch. This peninsula is generally referred to as the South Baltimore Peninsula, and includes the neighborhoods of Federal Hill, Locust Point, Riverside, South Baltimore, and Sharp-Leadenhall. While not physically a part of the peninsula, Otterbein is also included in the collection of neighborhoods which make up greater South Baltimore. Traditionally, Federal Hill was roughly triangular, bordered by Hanover Street to the west; Hughes Street, the harbor, and Key Highway to the north and east; and Cross Street to the south.
