This course will review history, basic applications, notable projects, and stormwater mitigation potential for urban trees, with a focus on suspended pavement systems. Suspended pavement makes two very important functions possible in urban settings: urban tree growth and on-site stormwater management. Many cities have implemented canopy coverage goals in order to attain a mature urban forest. Additionally, some cities have implemented soil volume mandates for street trees in order to meet those goals, like Washington DC’s DDOT Green Infrastructure Plan. Placing non-compacted soil beneath pavement to encourage tree growth has created an opportunity for stormwater management, through absorption, filtration, and bioretention. Several suspended pavement case studies will be discussed, including projects in the Nation’s Capitol, and the states of Maryland and Pennsylvania. The stormwater mitigation potential of the technique is based on research conducted by Drs. Bill Hunt, Ryan Winston, and Jonathan Page at NCSU in Wilmington NC, among others. Results show that tree/soil systems in suspended pavement can indeed provide stormwater benefits equal to (or better) than traditional bioretention systems.
