Walsh Community College Addition
Walsh College recently expanded their Troy Campus, and wanted a green vision for their new library. CDF was selected to design a sustainable landscape and parking lot for the expansion. Each parking lot median is a bioswale that contains specially blended porous topsoil, underlain by gravel. Rain water that runs off of the new parking lot is filtered through the topsoil and temporarily detained in the gravel below it, filtering the water of many of its pollutants. A constructed natural water feature replicates a natural wetland, providing habitat for submergent plants and the stable filtered flow of rain water means no additional potable water or chemical applications are necessary. Native tallgrass prairie species that once predominated the Midwest are now part of the Walsh College landscape. The landscape includes 7 native grasses and 33 flowering perennials. The result is a sustainable landscape that requires less fertilization and irrigation than a traditional lawn; and offers beautiful scenery that changes with the seasons.
