1.2.2.7 Urban

Definition: Those ecosystems dominated by man-made structures. Included in this category are cities, towns, villages, strip developments along highways, transportation, power, and communications facilities, and areas such as those occupied by mills, shopping centers, industrial and commercial complexes, and institutions that may, in some instances, be isolated from urban areas.

Urban Categories:

1.2.2.7.1 Commercial and Services Land: Those regions dominated by man-made structures where land is used predominantly to support the sale of products and services. This includes urban central business districts, shopping centers, commercial strip developments, junkyards, and institutional land uses such as schools, churches, correctional facilities and military installations, as well as supporting areas such as parking lots and warehouses. Noncommercial land uses embedded among commercial uses may be included unless the noncommercial uses exceed one-third of the total area.

1.2.2.7.2 Communication and Utility Land: Those regions dominated by land uses involved in processing, treatment, and transportation of water, gas, oil, and electricity, and areas used for airwave communications. This includes pumping stations, electric substations, and areas used for radio, radar, or television antennas. This does not include small facilities, or those associated with an industrial or commercial land use, such as long-distance gas, oil, electric, telephone, water that rarely consistitute the dominant use of the land and are included in other categories.

1.2.2.7.3 Industrial and Commercial Complexes: Those regions in which industrial and commercial land uses typically occur together or in close functional proximity. Such areas commonly are labeled with terminology such as "Industrial Park," but functions such as warehousing, wholesaling, and occasionally retailing may be found in the same structures or nearby.

1.2.2.7.4 Industrial Land: Those regions dominated by man-made structures where land predominantly supports the maufacture and production of goods, from light manufacturing focused on design, assembly and finishing, to heavy manufacturing that uses raw materials. This includes steel mills, pulp and lumber mills, electric-power generating stations, oil refineries and tank farms, chemical plants, and brickmaking plants.

1.2.2.7.5 Mixed Urban or Built-up Land: Those regions in which more than one-third of the land is a mixture of Urban and Built-up land uses. This typically includes developments along transportation routes and in cities, towns, and built-up areas.

1.2.2.7.6 Other Urban or Built-up Land: Those regions dominated by man-made structures that do not fall into the other categories of urban and built-up land (residential; commercial and services; industrial; transportation, communications, and utilities; industrial and commerical complexes; mixed urban or built-up). This includes golf driving ranges, zoos, urban parks, cemeteries, waste dumps, water-control structures and spillways, and undeveloped land within an urban setting.

1.2.2.7.7 Residential Land: Those regions dominated by man-made structures that provide human housing. This includes both high population density uses, represented by the multiple-unit structures of urban cores, and low population density uses, where houses are on lots of more than an acre, on the periphery of urban expansion. Rural residential developments and developments along transportation routes extending outward from urban areas also are included. This does not include commercial strips in those localities.

1.2.2.7.8 Transportation Land: Those regions dominated by man-made structures where land is used primarily to support transportation facilities. This inclues highways (including rights-of-way, areas used for interchanges, and service and terminal facilities), rail facilities (including stations, parking lots, roundhouses, repair and switching yards), airports (including runways, intervening land, terminals, service buildings, navigation aids, fuel storage, parking lots, and a limited buffer zone), seaports and major lakeports (including docks, shipyards, drydocks, locks, and waterway control structures).
