Document 4: Queens: Queens is the easternmost and largest in area of the five boroughs of New York City.

Coterminous with Queens County since 1899, the borough of Queens is the second-largest in population (after Brooklyn), with a census-estimated 2,333,054 residents in 2016, approximately 48% of them foreign-born.

All but one of the buildings are in residential use and the majority were built in the early- to mid-20th century as a planned suburban community known as Douglas Manor. In the early 20th century, the Rickert-Finlay Realty Company of Manhattan purchased 175 acre of the Douglas' family holdings, and formed the Douglas Manor Association, creating a planned community. Many of the houses in this area were built in architectural styles popular at the time, such as Tudor, Mediterranean, Colonial Revival, and Arts and Crafts. Located within the district are the separately listed Cornelius Van Wyck House (c. 1735) and Allen-Beville House (c. 1848-1850).

There are many trails to walk about surrounded by an array of diverse trees and shrubs. Some of the types of trees and shrubs include red cedar, flowering dogwood, highbush blueberries, white pine, and speckled alder. The main trail is a 0.5 mi loop. Mulched side trails, which branch off the main trail, add another 0.5 mi to walk. Community volunteers maintain the park. They have erected many bluebird boxes and bat houses to house some of the natural wildlife of the park. There are also vernal pools, which are habitats for salamanders and wood frogs in the southeast corner of the park. There is even a 200-year-old sugar maple, which is called the “bee tree,” in which a large colony of bees has made it their home.

The site includes Brooklyn Piers 1–6, the historic Fulton Ferry Landing, and the preexisting Empire–Fulton Ferry and Main Street Parks. Two Civil War-era structures, Empire Stores and the Tobacco Warehouse, will also be integrated into the park.

Document 10: New Creek (Staten Island): The New Creek watershed encompasses 2220 acre on the East Shore of Staten Island, New York. The creek is fed by many natural springs in the area, which were used by the Lenape Indians before the arrival of European colonists in the Seventeenth Century. Many of the springs have been channeled underground by urban development as the population expanded throughout New York City. The watershed consists of marshland which supports a variety of flora and fauna. Spartina grass flourished in a tidal wetland before the restoration of the shore and beach area and the development of a shoreline urban park by the New York City Department of Parks and Recreation in the 1960s, blocking tidal flow to the area.
Document 11: Bates Pond (Carver, Massachusetts): Bates Pond is a 20 acre pond in Carver, Massachusetts. The pond is located south of Edaville Railroad. Huckleberry Corner lies along the southern shore of the pond. The water quality is impaired due to non-native plants in the pond.
Document 12: Ponquogue Parkway: In 1938, after the destruction to Fire Island from the Long Island Express hurricane, Robert Moses and W. Earle Andrews, both part of the Long Island State Park Commission, proposed reconstruction of the island. This proposal included an extension of the Ocean Parkway out from its terminus at Captree State Park across Fire Island to Westhampton. This new parkway, which would boast 22 ft wide roadways, would have connections back to the mainland at Smith Point County Park and Ponquogue with parkway spurs across Shinnecock Bay and the Great South Bay. The new spur at Ponquogue, deemed the Ponquogue Parkway, would have marked the eastern terminus of the new Ocean Parkway extension. The proposal lived until the cut-back to Smith Point County Park in 1962 for environmental issues with such a construction, ending any proposal for a parkway in the area of Hampton Bays.
Document 13: Potamogeton Pond: Potamogeton Pond, a small pond in Queens, New York City (historically also known as Pea Pond), is located on a narrow strip of parkland in Hollis Hills alongside Grand Central Parkway and named after an aquatic plant. It was once a stop on a bridle trail that connected Cunningham Park to Alley Pond Park; but when local stables closed, the trail became disused. The pond can be found at 86th Avenue and 217th Street. The completion of Grand Central Parkway reduced the amount of water that fed the pond, resulting in less water intake and converting the once popular ice-skating site to a bog. The perch, carp and catfish that lived in the pond died off in 1963 as the parkway was widened in conjunction with the world’s fair taking place in Flushing Meadows the following year. Silt covered up the pond, and plants grew atop its former surface.

It lies at the north end of a spit of land dividing North Sandy Pond from Lake Ontario, and is about 2 mi north of the developed portion of Sandy Island Beach State Park. There is no road access to the area, which can be most easily reached by boat. For this reason, local residents have long referred to the beach as "Boaters' Beach". It has been managed as part of Sandy Island Beach State Park since 2011.
