Ginter Park is a suburb neighborhood of Richmond, Virginia built on land owned and developed by Lewis Ginter.  The neighborhood's first well known resident was newspaperman Joseph Bryan, who lived in Laburnum, first built in 1883 and later rebuilt .  In 1895, many acres of land north of Richmond were purchased by Ginter in order to develop into neighborhoods.  Ginter Park and other neighborhoods were developed from this initial land purchase.

Lake Cunningham is an artificial lake in Lake Cunningham Park, in East San Jose, California, near the Eastridge Mall and Eastridge Transit Center.

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. Thornewood Open Space Preserve is a small regional park located in the Santa Cruz Mountains in San Mateo County.

The Susquehanna and Tioga Turnpike; also called the Berwick and Tioga Turnpike, and Susquehanna & Tioga Turnpike connecting via the high ground of tributary valleys Berwick and upstream, Tioga—chartered & incorporated in 1806, the toll road, like many middle ages toll roads in Europe was opened initially as a animal power (foot traffic) turnpike in northeastern Pennsylvania (eventually) connecting early Central & Northern Eastern Pennsylvania along the Main Branch Susquehanna River to Lower New York State.  Established in the early American canal age, and undercapitalized , it took several years to gradually extend improved trails in stages 100 mi to Elmira, New York from its southern terminus at Berwick, Pennsylvania opposite Nescopeck across the Susquehanna River—in this manner it initially also sufficed as a bridle trail as well.  Where demand existed from sources of natural resources or farmers seeking to ship farm goods to markets, it was systematically widened and improved into a wagon road.
