Development of Soil Mix and Plant Materials for Washington Bridge #200 Reconstruction

The Washington Bridge 200 Reconstruction includes planted planters, along the pedestrian/bicycle path, which require minimal annual maintenance and irrigation, and must be able to tolerate environmental conditions while being less prone to vandalism yet attractive for most of the year when the path is in use. Only a few types of plant material are capable of surviving the extremes of cold and heat, limited irrigation, and potential for salt exposure that will characterize the Washington Bridge planters. Furthermore even fewer plant types really require little or no maintenance while still remaining attractive to public view. Fortunately an emerging technology for using plant materials to cover large expanses of bituminous flat roof, as a means to reduce runoff and temperature loading, utilizes plants and growing methods that might be suitable to this project. Key concepts implicit in this research are the use of green roof technology and plant materials as a starting point in developing a sustainable, low-maintenance technology suitable for Rhode Island climate as well as environmental and edaphic conditions particular to the Washington Bridge #200 Reconstruction Project. The ideal result of the project would be vegetated planters that require no supplemental watering and bare-minimum maintenance, while being exceptionally attractive in terms of foliage and flower display year-around - a model for sustainable landscaping in an urban setting.
