Pelham Islands

Davids Island is a 78-acre (320,000 m2) island off the coast of New Rochelle, New York, in Long Island Sound. Currently uninhabited, it was previously the site of Fort Slocum. The island is home to the endangered Kemp's ridley sea turtle, and birds such as osprey and least terns. Davids Island also supports valuable wetlands, rare rocky intertidal areas, and sandy beaches. The waters surrounding the island are home to winter flounder, Atlantic herring, and Atlantic silverside.

Fort Slocum, New York was a US military post which occupied Davids Island in the western end of Long Island Sound in the city of New Rochelle, New York from 1867 to 1965. The fort was named for Major General Henry W. Slocum, a Union corps commander in the American Civil War.

Columbia Island (formerly Little Pea Island), is an island in the Long Island Sound and part of New Rochelle, New York. It is situated off the south-eastern coast of Davids' Island, immediately adjacent to Pea Island. The island varies in size from about one acre to 175 square feet depending on the tide. It was once owned by the Iselin family who sold it to the Huguenot Yacht Club along with Pea Island in 1936. Three years later the club sold Little Pea Island to the Columbia Broadcasting System, which appropriately renamed it "Columbia". As a result of engineering surveys designating the area around New Rochelle and Port Washington on Long Island Sound as the ideal locality for a radio transmitter to serve the metropolitan New York area, new stations were constructed on these sites by both the Columbia ("CBS") and National ("NBC") broadcasting systems in 1940. CBS purchased the island as the site for a new broadcast antenna tower for WCBS (then known by the call sign WABC).CBS spent approximately $500,000 to construct the transmitter building with emergency housing for ten workers, and the 410-foot (125 m) broadcast tower. The station contained a 50,000-watt transmitter housed in a 75-square-foot (7.0 m2) copper-walled building. There also was a 5,000-watt transmitter unit for emergency use. Electric power was supplied through two submarine cables, which were connected to separate power plants to prevent interruption of service. Emergency generators were installed on the island for protection against power failure. The men who operated the station lived within a grounded metal shell under which were living quarters for engineers, workshops, electrical units that supplied tube voltages, and the backup generator. The transmitter remained in operation until 1963, when it became obsolete, and the station was moved to nearby High Island. CBS's work to build a high-power broadcasting station included drilling through bedrock to a source of fresh water, found at a depth of 910 feet (280 m).The island was then purchased by the show-business couple Peter Lind Hayes and Mary Healy, who broadcast a breakfast conversation show from their home there. It was part of a package that included a strip of waterfront property, a speedboat, and a tugboat. The couple later gave the island to the College of New Rochelle. In 2005, the then-current owner of the island sought to demolish the old transmitter building and replace it with a private residence. Pathologist Al Sutton bought Columbia Island in 2007. To make the island more livable, he constructed an off-the-grid "green" home within the concrete building with solar panels. In June 2019, Columbia Island and nearby Pea island were jointly put on sale with a list price of $13 million. According to The New York Times Sutton described the property as a "money pit". Sutton spent $8 million on the property.

The Glen Island Park Bath House, located in the city of New Rochelle in Westchester County, New York, is a contributing resource in the National Register eligible Glen Island Park. The park was originally purchased by transportation industrialist, John Starin, in 1875 to serve as a summer resort for the wealthy in New York City. By the 1920s, with suburban growth rapidly increasing in Westchester County, the park was purchased by the Westchester County Parks Commission to provide recreational space for almost two million visitors a year in the early 1930s. Glen Island Park is eligible for the National Register of Historic places under Criterion A for its association to recreation and Criterion C for its architecture with its Colonial Revival Style buildings. The Glen Island Park’s landscape was designed by the notable early twentieth century New York City area landscape architect, Gilmore David Clarke. The mid-1920s design displays many features that survive today including a five span steel arch drawbridge to the mainland, a tree lined road terminating at a roundabout, parking lots, and a bath house separating the enlarged crescent shaped beach from a circular play field. The park’s circulation pattern prioritizes personal automobile transportation with the character and use of the park remaining consistent for over 80 years.

Huckleberry Island (or Whortleberry Island) is an island in Long Island Sound and part of New Rochelle, New York. It lies approximately three-fourths mile (1.2 km) east of Davids' Island. The 10 acres (4.0 ha) island consists primarily of deciduous forest with virtually no shrubs or herbaceous growth under the canopy. The rocky shoreline supports a marine rocky intertidal community comprising one of the most southerly occurrences of this community type on the North Atlantic Coastline.In the 19th century local tradition held that the island was the location of the buried treasure of Captain William Kidd, one of the most well-known pirates in history.

Glen Island Park is a 105-acre (0.42 km2) waterfront park, located on Glen Island, on the Long Island Sound, New York. The park is owned and operated by Westchester County and shares the island with a privately operated but county-owned entertainment facility, the Glen Island Harbour Club (formerly the Glen Island Casino) The Glen Island Casino was a springboard to success during the 1930s Big Band Era, including that of Ozzie Nelson, Charlie Barnet, Claude Thornhill, Les Brown, The Dorsey Brothers and Glenn Miller.

Echo Bay is an embayment located off Long Island Sound in the city of New Rochelle in Westchester County, New York. It is an anchorage for small craft and is generally fully occupied during the summer. The depths at the anchorage range from 4 to 15 feet, and launches can anchor in the shallow cove on the northeast side of the harbor, entering between Harrison Islands and the rocky, grassy islet off the northwest side of Echo Island. Vessels frequently anchor between the entrance of Echo Bay and Hicks Ledge, in depths of 20 to 24 feet. On the northwest side of Echo Bay a dredged channel 100 feet wide and 15 feet deep, marked by buoys, leads to the New Rochelle Municipal Marina at Beaufort Point (Hudson Park).

New Rochelle Harbor is the name of a harbor located along Long Island Sound in the city of New Rochelle in Westchester County, New York. The Davenport Neck peninsula off the mainland divides New Rochelle's waterfront into two bays; the westerly referred to as New Rochelle Harbor and the easterly as Echo Bay. The upper portion the harbor lying behind Davenport’s Neck is known as "New Rochelle Creek". It extends in a northerly direction about a mile from the main entrance to the harbor east of Glen Island. Titus Mill-Pond is located at the northeastern end of the creek. The "Lower Harbor" is the long, narrow channel between Travers, Neptune and Glen islands. The entire harbor is protected from rough water and storms in Long Island Sound by Davenport Neck, Glen Island, and Hunters Island.The Lower Harbor area is the site of a considerable amount of boating activity since it contains the mooring areas of the New York Athletic Club on Travers Island, and the Huguenot Yacht Club, and boatyards on the southerly half of Neptune Island. Also using the waters of the Lower Harbor are two boat launching ramps at Glen Island Park. The inner portion of the harbor is used by only a few boats, since most of its waters do not have sufficient depth. The harbor has a length of about 6,500 feet and width of from 500 to 600 feet. The main entrance channel to the harbor lies between Davenport Neck and Glen Island. Access to the Lower Harbor from this entrance also involves passing under a bascule bridge connecting Glen Island to the mainland. Every time a boat enters or leaves the Lower Harbor, it requires the opening of the bridge, thus necessitating twenty-four-hour bridge tender staffing. A second entrance channel, between Glen Island and Hunters Island. Other channels exist between the several islands which lie on the Long Island Sound side of the harbor and protect the latter from easterly storms. Of these channels, one passes between Glen Island and Goose Island and another lies between Davids Island and Goose Island. The waters surrounding and in the immediate vicinity of these islands as well as the entrance channels are obstructed by numerous rocks.The shoreline of New Rochelle Harbor contains a mix of recreational and marine commercial uses, and medium and high-density residential development. Recreational uses are predominant in the Lower Harbor, and include: Glen Island County Park, Glen Island Yacht Club, the New York Athletic Club Yacht Club, Huguenot Yacht Club. Additional marinas are arranged along the shoreline, with commercial and residential uses situated along Pelham Road in the upper harbor area.

Neptune Island is an island in Long Island Sound and part of the City of New Rochelle, New York. It is connected to the mainland by a stone causeway topped by Neptune Road. A dam at the peninsula's east end creates a small pond, and its west shore edges the Neptune Basin inlet.

Davenport Neck is a peninsula in New Rochelle, New York, extending southwesterly from the mainland into Long Island Sound, and running parallel to the main shore. It divides the city's waterfront into two, with New Rochelle Harbor to the south and southwest, and Echo Bay, to the north and northeast. Glen Island and Neptune Island lie just to the west of the Neck, and Davids' and Huckleberry islands lie to the south. The Neck is one of the most important historical localities in the City of New Rochelle. Before white settlements, Siwanoy Indians encamped here, finding an abundant source of fish and wildlife. Until the early 19th century tidal mills produced flour and other goods for local use and for export. With the advent of steamboat, and the resorts and inns that sprang up along the waterfront as a result, New Rochelle became an enormously popular destination by the mid-1800s. Davenport Neck was the choice location for the "summer homes" of wealthy vacationers.

Pine Island is a small, privately owned island in the city of New Rochelle in Westchester County, New York. The island is situated off the coast of Davenport Neck near Sans Souci Beach in Long Island Sound.
