I live near a few city parks, but this one is something special.
Last year this public playground was transformed from what had been a cement playground with outdated equipment, very little grass or other vegetation, and a traditional cement basketball court in the Pennsport section of South Philadelphia.
The old playground and pool was converted to a state-of-the-art green project, now called Herron Playground, that is a model site to demonstrate the broader plans for the greening of Philadelphia. It employs porous paving for sidewalks and basketball court, recycled material as playground surface, drainage beds and pipes to carry excess water into a retention basin full of native plant species, and islands of vegetation for retaining water and slowing runoff.
Herron Playground is a fantastic example of trying to mimic nature’s methods of dealing with excessive storm water in an urban environment where for generations most land has been paved over with impervious surfaces (cement or asphalt or other paving materials which water cannot penetrate), causing major problems when there is a heavy rainfall and water has nowhere to go, so it just sheets off into the street and rushes into the nearest storm drain, overloading the city’s sewer system often just from the first inch of rain of a typical rainstorm.

changing climates increasing Africa’s already intolerable disease burden, scientists must begin to reach out to colleagues in other fields and to the people they want to help if they hope to avert an expected “continental disaster,” according to leading climate, health, and information technology experts, who met in Nairobi last week.
