Mary Bartelme Park offers the neighborhood much needed open-space, a children’s playground and a dog play area. Besides the uses commonly found in an urban park the project includes innovative features conceived by Site Design Group, an award-winning Chicago landscape architecture firm. Five large stainless steel gateway structures twist through a field of brilliant white Eco-Priora™ TX Active permeable pavers. Sun rays activate the photo catalytic reaction within the concrete and destroy organic and inorganic compounds before they have a chance to adhere to its surface. The organic pollutants decompose into oxygen, water and harmless salts. While the photo catalytic properties of the pavers clean the air on a clear day, on a rainy day their permeable solution allows rainwater to flow through their surface rather than being discharged into sewers.
