WSUD Strataflow tree pit systems can be configured in a number of ways depending on specific site opportunities and constraints. The fundamental elements of a WSUD tree pit system include the following; • Sufficient structural soil volume to facilitate tree growth and root expansion • Available impervious catchment for passive watering • Inlet for stormwater supply to tree • Suitable tree species • Treatment element for management of solids and pollutants in stormwater • Drainage layer and stormwater outlet connection (as required) A design procedure has been prepared to assist specifiers and designers with the integration of WSUD features into Strataflow Tree pit systems. The procedure is presented as a flowchart which describes the general steps involved in the design process. A detailed explanation of some of the key design considerations is also provided - request a copy of this document
