Though some exceptions may apply, the key new requirements include:

  1. All construction dewatering/drainage must be supported by a short-term Use Approval under the Water Sustainability Act.  Such work must not cause negative impacts to human health, property, infrastructure, environment, or groundwater resources on or off-site.
  2. Preliminary / Final Hydrogeological Studies are now required for a wider range of projects, including:
  • Rezoning and development permit applications in ‘Areas of Concern’ for groundwater.  These include sites where soils are sensitive to water table fluctuations, within the Cambie Corridor sewershed, and within the Flowing Artesian Well advisory area. 
  • Development Permit applications within the Cambie Corridor sewershed, excluding SF homes, duplexes, and laneway homes.
  • Rezoning applications subject to the Rezoning Policy for Sustainable Large Developments, anywhere in the City.
  • Open-Loop Geoexchange systems, anywhere in the City.
