CHAPTER 4
PARKS, OPEN SPACE AND GREENWAYS PLAN
■ TODAY’S CONDITIONS
Across the nation, easy access to parks and open space has become a new measure of community wealth – an important way to attract businesses and residents by guaranteeing both healthy communities and economic health. Recent research indicates that the health outcomes of individuals are determined to a large degree by the environments in which they live. According to the Center for Healthy Communities, environmental factors unrelated to the health care delivery system – like air and water quality and access to parks and recreation – are vital to a healthy life. Businesses are free to shop for an appealing location and today, according to the Trust for Public Land, prefer communities with a high quality of life, including an abundance of open space, nearby recreation and pedestrian-friendly neighborhoods.
Parks, open space and greenways provide a variety of benefits that contribute to livable communities including economic, environmental, recreational, educational and heath benefits.
THE BENEFITS OF OPEN SPACE
According to the 1995 Allegheny County Greenways Plan, parks, open space and greenways provide a variety of benefits that contribute to livable communities. Some of these benefits include:
- ■ Economic benefits – attracting and retaining businesses, increasing property values by making communities more desirable, enhancing place identity, and reducing public costs through better management of natural events such as flooding.
- ■ Environmental benefits – protecting natural areas, protecting and improving water quality, improving air quality, reducing flooding and related stormwater damage, and protecting wildlife corridors that link habitats.
- ■ Recreational and transportation benefits – providing opportunities for rails-to-trails, commuter bikeways, and riverfront development, and enhancing road and highway corridors.
- ■ Educational benefits – providing outdoor classrooms for children and adults.
- ■ Health benefits – increasing opportunities for exercise and reducing stress.
DEFINITIONS
The following definitions are provided for the purposes of this Plan. Some types of facilities, such as trails, may fit more than one definition.
Conservation Areas: open spaces, primarily undeveloped land, that have the specific purpose of protecting natural resources.
DCNR: the Pennsylvania Department of Conservation and Natural Resources.
Greenways: corridors of open space that serve to link natural resource-based or manmade features. Greenways may incorporate both public and private property and be either land- or water-based. Greenway corridors often follow abandoned railways, canals, ridge tops, rivers and stream valleys. Greenways can have many functions:
- ■ Conservation Greenways: unimproved corridors primarily intended for natural resource protection.
- ■ Major Greenway Corridors: long-distance corridors (at least 50 miles long) that pass through two or more counties and are recognized in official planning documents by counties. They represent the major “arteries” of the developing statewide greenway system.
- ■ Mega Greenways: greenways of one hundred miles or more, with a completed plan.
- ■ Recreational Greenways: corridors that accommodate hiking trails or bikeways, water trails and multi-use trails.
Greenways Network: a linked system of greenways and hubs of specifically identified natural resources or open space and manmade features or destinations that influence the development of the linear greenway corridor.
