A sidewalk, pavement, footpath in Australia, India, New Zealand and Ireland, or footway is a path along the side of a road. Usually constructed of concrete, pavers, brick, stone, or asphalt, it is designed for pedestrians. A sidewalk is normally higher than the roadway, and separated from it by a kerb. There may also be a planted strip between the sidewalk and the roadway and between the roadway and the adjacent land.
A street is a public thoroughfare in a built environment. It is a public parcel of land adjoining buildings in an urban context, on which people may freely assemble, interact, and move about. A street can be as simple as a level patch of dirt, but is more often paved with a hard, durable surface such as tarmac, concrete, cobblestone or brick. Portions may also be smoothed with asphalt, embedded with rails, or otherwise prepared to accommodate non-pedestrian traffic.
A curb extension is a traffic calming measure which widens the sidewalk for a short distance. This reduces the crossing distance and allows pedestrians and drivers to see each other when parked vehicles would otherwise block visibility. The practice of banning car parking near intersections is referred to as daylighting the intersection.
A boulevard is a type of broad avenue planted with rows of trees, or in parts of North America, any urban highway or wide road in a commercial district.
A living street is a street designed with the interests of pedestrians and cyclists in mind by providing enriching and experiential spaces. Living streets also act as social spaces, allowing children to play and encouraging social interactions on a human scale, safely and legally. Living streets consider all pedestrians granting equal access to elders and those who are disabled. These roads are still available for use by motor vehicles; however, their design aims to reduce both the speed and dominance of motorized transport. The reduction of motor vehicle dominance creates more opportunities for public transportation.
A driveway is a private road for local access to one or a small group of structures owned and maintained by an individual or group.
The Millionaires' Mile, Millionaires' Row, Billionaires Row, Golden Mile or Alpha Street are the exclusive residential neighborhoods of various cities, often along one scenic strip such as a riverside or hilltop drive, or a wide city boulevard.
The River Rouge is a 127-mile river in the Metro Detroit area of southeastern Michigan. It flows into the Detroit River at Zug Island, which is the boundary between the cities of River Rouge and Detroit.
Guerrilla gardening is the act of gardening – raising food, plants, or flowers – on land that the gardeners do not have the legal rights to cultivate, such as abandoned sites, areas that are not being cared for, or private property. It encompasses a diverse range of people and motivations, ranging from gardeners who spill over their legal boundaries to gardeners with a political purpose, who seek to provoke change by using guerrilla gardening as a form of protest or direct action.
Bioswales are channels designed to concentrate and convey stormwater runoff while removing debris and pollution. Bioswales can also be beneficial in recharging groundwater.
Alewife Brook Reservation is a Massachusetts state park and urban wild located in Cambridge, Arlington, and Somerville. The park is managed by the state Department of Conservation and Recreation and was established in 1900. It is named for Alewife Brook, which was also historically known as Menotomy River, a tributary of the Mystic River.
Broad Street is a major arterial street in Philadelphia, Pennsylvania. The street runs for approximately 13 miles (21 km), beginning at the intersection of Cheltenham Avenue on the border of Cheltenham Township and the West/East Oak Lane neighborhoods of North Philadelphia to the Philadelphia Navy Yard in South Philadelphia. It is Pennsylvania Route 611 along its entire length with the exception of its northernmost part between Old York Road and Pennsylvania Route 309 and the southernmost part south of Interstate 95.
A curb, or kerb, is the edge where a raised sidewalk or road median/central reservation meets a street or other roadway.
Rain gardens, also called bioretention facilities, are one of a variety of practices designed to increase rain runoff reabsorption by the soil. They can also be used to treat polluted stormwater runoff. Rain gardens are designed landscape sites that reduce the flow rate, total quantity, and pollutant load of runoff from impervious urban areas like roofs, driveways, walkways, parking lots, and compacted lawn areas. Rain gardens rely on plants and natural or engineered soil medium to retain stormwater and increase the lag time of infiltration, while remediating and filtering pollutants carried by urban runoff. Rain gardens provide a method to reuse and optimize any rain that falls, reducing or avoiding the need for additional irrigation. A benefit of planting rain gardens is the consequential decrease in ambient air and water temperature, a mitigation that is especially effective in urban areas containing an abundance of impervious surfaces that absorb heat in a phenomenon known as the heat-island effect.
Nonpoint source (NPS) pollution refers to diffuse contamination of water or air that does not originate from a single discrete source. This type of pollution is often the cumulative effect of small amounts of contaminants gathered from a large area. It is in contrast to point source pollution which results from a single source. Nonpoint source pollution generally results from land runoff, precipitation, atmospheric deposition, drainage, seepage, or hydrological modification where tracing pollution back to a single source is difficult. Nonpoint source water pollution affects a water body from sources such as polluted runoff from agricultural areas draining into a river, or wind-borne debris blowing out to sea. Nonpoint source air pollution affects air quality, from sources such as smokestacks or car tailpipes. Although these pollutants have originated from a point source, the long-range transport ability and multiple sources of the pollutant make it a nonpoint source of pollution; if the discharges were to occur to a body of water or into the atmosphere at a single location, the pollution would be single-point.
Fresh Pond Parkway is a historic park and parkway on the western end of Cambridge, Massachusetts. It is part of the Metropolitan Park System of Greater Boston. The parkway was built in 1899 and added to the National Register of Historic Places in 2005.
Urban runoff is surface runoff of rainwater, landscape irrigation, and car washing created by urbanization. Impervious surfaces are constructed during land development. During rain, storms, and other precipitation events, these surfaces, along with rooftops, carry polluted stormwater to storm drains, instead of allowing the water to percolate through soil. This causes lowering of the water table and flooding since the amount of water that remains on the surface is greater. Most municipal storm sewer systems discharge untreated stormwater to streams, rivers, and bays. This excess water can also make its way into people's properties through basement backups and seepage through building wall and floors.
Xeriscaping is the process of landscaping, or gardening, that reduces or eliminates the need for irrigation. It is promoted in regions that do not have accessible, plentiful, or reliable supplies of fresh water and has gained acceptance in other regions as access to irrigation water has become limited, though it is not limited to such climates. Xeriscaping may be an alternative to various types of traditional gardening.
Sustainable landscaping is a modern type of gardening or landscaping that takes the environmental issue of sustainability into account. According to Loehrlein in 2009 this includes design, construction and management of residential and commercial gardens and incorporates organic lawn management and organic gardening techniques.
The Indianapolis Park and Boulevard System is a group of parks, parkways, and boulevards in Indianapolis, Indiana, that was designed by landscape architect George Edward Kessler in the early part of the twentieth century. Also known as the Kessler System, the district includes 3,474 acres (1,406 ha) and has shaped the city through the present day. This historic district was added to the National Register of Historic Places in 2003.
