Streetscale raingardens – design & practice

In-house training

Streetscale raingardens – design and practice (PDF)

Overview

This course offers practitioners knowledge and skills to plan and design streetscale raingardens to ensure long-term success, including selection and placement of vegetation. It includes an afternoon session with three of Adelaide’s leading WSUD practitioners who will share their learnings from Raingarden 500 pilot projects.

Learning objective

The training will assist participants to improve knowledge and skills with respect to appropriate design parameters and practices necessary to enable the delivery of successful biofiltration assets.

Audience

Engineers, landscape architects and designers and urban designers
