The City is excited to be constructing a series of raingarden bulges in Queen’s Park as a demonstration project for the Citywide Integrated Stormwater Management Plan (ISMP). The scope of work includes new infiltration bulges and associated storm water works for drainage improvement, construction of new curb/gutter/sidewalks for improved pedestrian connections, landscaping & repaving of the disturbed areas of the site.
The raingardens will act as ‘water focal point’ in the Queen’s Park watershed - a place where the quality and quantity of water, and the life it supports, can be seen (and monitored / improved). This pilot also builds comfort and confidence among staff and contractors and the skills to improve the implementation of future green infrastructure projects.
About the ISMP
The Metro Vancouver Integrated Liquid Waste Resource Management Plan (ILWRMP) specifies that Integrated Stormwater Management Plans (ISMP) be completed for each watershed within Metro Vancouver.
An ISMP is important to the City to:
- Reduce the volume of water in our sewers to reduce combined sewer overflows and flooding;
- Strive for high-quality water to protect our receiving waters;
- Return rainwater where possible to natural watershed pathways using best management practices such as rain gardens, absorbent soils, and landscapes;
- Raise awareness of the importance of stormwater management in New Westminster including innovative tools to help our city become a resilient community in the face of climate change
Implementing Green Infrastructure will improve water quality to protect the environment, support recreational water use, and meet current and emerging regulatory requirements.
Given the pilot nature of this initiative and upcoming demonstration projects in other drainage catchments, we will continue to monitor the success of these green infrastructure and modify our practices based on performance, the latest research, best practices and feedback from the community.
