Urban Green Spaces

Traditionally, urban "green spaces" such as meadows, wooded areas and other natural areas were found only in parks, but more recently urban green spaces include urban forestry. The ability to experience green spaces in Urban Landscapes is useful for promoting physical and emotional health and general well-being. Urban green space provides relief from the hardscape that is prevalent in urban environments, and offers opportunities for both passive and active recreation. The provision of urban green spaces has become an essential element of public health policy. This tool examines the process of establishing, expanding and improving urban public parks, forests and recreation facilities.


The establishment of urban parks, forestry, green spaces and recreation facilities offer residents the following advantages:


The establishment of urban parks, forestry, green spaces and recreation facilities can be subject to the following limitations:

An urban municipality that is interested in establishing parks, forests and recreation facilities should revise its future land use map in its comprehensive plan to identify areas where these uses would be located. This might include the creation of a new category on the future land use map or a text revision to add these uses to the existing appropriate use category. The municipality should also consider creating an official map that identifies parcels and corridors that could accommodate the establishment of parks, urban forests and recreation facilities. The municipality should then review its zoning ordinance to add these uses to the applicable zoning district or create a new zoning district that would specifically accommodate these uses.

Municipal policy makers should be flexible regarding the location of urban green features. These elements can involve use of abandoned industrial sites and river or stream corridors as well as unused transportation facilities and infrastructure. A notable example of a transportation facility that was converted into an urban green space is the High Line on New York City's west side, which converted an unused elevated railway into a linear greenway and park. Since its opening in 2009, The High Line attracted over two million visitors and is expected to generate economic benefits for the surrounding neighborhoods.

The municipality should also specifically permit a range of appropriate active and passive recreational activities in the urban park and forest area. By encouraging a variety of activities, public safety can be enhanced and a wide range of recreational needs can be met. Additional support facilities may also be needed, such as water fountains or shops and restaurant that meet the needs of the park's users.

Parks, recreation facilities and urban forests could be combined on a single former industrial site or form nodes in urban trail networks. Urban forests could be combined with a trail network along river and stream corridors. This would help stabilize steep banks, improve water quality by shading the river or stream for fresh water fish species, provide shade for the trail users while improving the scenery, suppressing noise, improving air quality and serving as a buffer between different areas of the city.

As an element of urban infrastructure, the trees themselves can outlast nearly all man-made structures. For example, some species of hardwoods in the northeastern United States have average lifetimes of 150-200 years. Depending on the site of an urban forest and the actual growing conditions, a municipality could develop an urban forestry plan that also involves tree harvesting. If furniture quality hardwoods specie were planted and replaced as they were harvested, in the long term an urban forest might even be self-supporting. (However, many sawmills will not accept urban trees due to the potential presence of embedded nails or wires that can damage sawmill equipment. Care must be taken to find an appropriate user for urban timber.)

Traditionally in the Urban Landscape, land for parks and recreation was in low supply and often expensive to acquire. More recently, the availability of land and acquisition price has become more attractive to municipalities and non-profit groups, due in part to changes in the country's industrial base, with large urban locations for industries such as the steel industry becoming available for redevelopment. This is the case for the City of Coatesville and Phoenixville Borough. Both Coatesville and Phoenixville are redeveloping former foundries and steel mills. While such brownfields can include negative aspects related to their previous uses, they can be extensive in area and are comparatively flat.



City of Coatesville's Riverwalk

The Riverwalk in the City of Coatesville is a trail that begins at a former steel mill site on Route 30 and continues north along the Brandywine River. The trail will accommodate pedestrians and bicyclists. In the Borough of Phoenixville, the Strategic Plan for the French Creek Corridor and Downtown Business District describes three trail sections that traverse the former steel mill site along both sides of the French Creek. These trail sections will link up with surrounding regional trail networks.

The protection of natural resources is a required component of a municipal or multi-municipal comprehensive plan that is authorized in the Pennsylvania Municipalities Planning Code (MPC). Section 301.(a)(6) states that the comprehensive plan shall contain a plan for the protection of natural resources including, but, not limited to, wetlands and aquifer recharge zones, woodlands, steep slopes, prime agricultural land, floodplains, and unique natural areas. These areas can also be found in urban landscapes. The Pennsylvania Municipalities Planning Code can be accessed online.
