The following is the second installment of the two-part series excerpted from the Trust for Public Land’s (TPL) Center for City Park Excellence (CCPE) publication, City Parks, Clean Water: Making Great Places Using Green Infrastructure. To view Part I, click here.
Different Solutions and How They Actually Work
There is no simple formula for green infrastructure in parks. For one thing, geography alone dictates that there are dozens of different kinds of urban parks, from narrow stream side greenways to large flat forestland, from stepped brick plazas to lush community gardens, and from windswept hilltop viewpoints to massive sports complexes. But when it comes to water-smart parks, there are three principal issues:
- Is the physical relationship of the park to the surrounding community such that a redesign could reduce neighborhood flooding or the pollution of downstream waterways?
- Does the park have any available space for water flow and storage?
- Is the composition of the existing soils, water table, and underlying rock such that the park can absorb a significant amount of water in the necessary amount of time?
