Queen's Park Rain Gardens
The City has finished construction of the rain gardens in Queen’s Park. These rain gardens serve as a demonstration project for the Citywide Integrated Stormwater Management Plan (ISMP). The scope of work included 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 rain gardens 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
The New Westminster Citywide Integrated Stormwater Management Plan (ISMP) was presented to City Council in May of 2017.  Council supported the adoption of the New Westminster ISMP plan including Green Infrastructure tools and design guidelines for implementation on public and private property throughout the City.

Implementing Green Infrastructure will improve water quality to protect the environment, support recreational water use, and meet current and emerging regulatory requirements.

WHAT's Next

Given the pilot nature of this initiative and upcoming demonstration projects in other drainage catchments, the City 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.
