Trees Help Cities Meet Clean Water Regulations

The EPA has identified over $300 billion for nonintegrated water supply and wastewater projects for U.S. cities in the next 20 years. Those funds can be leveraged to solve multiple problems and improve the quality of life of urban residents by incorporating green infrastructure and strategically-planted trees in building and landscaping designs.
Tree cover in urban areas can not only reduce cities' costs for stormwater management but also help them improve water quality, offer shade, scrub the air of emissions and reduce ambient temperatures. Landscape architects and engineers need to think of the soil and the trees as mini reservoir systems designed to filter water and air.
