# Summary
# Excellence
Awarded where the development aligns with sponge city principles, as outlined in the Stormwater Management Strategy (SWMS) or Integrated Water Management (IWM) Plan.
This includes retaining, slowing, and reusing water through visible WSUD assets like swales, wetlands, and rain gardens to support biodiversity, amenity, and urban cooling.
Opportunities to integrate stormwater harvesting into open space or sports fields may further enhance outcomes.
