Large Properties 1 ha in size or greater:

  • 5,500 Large Properties that are one hectare or greater (1% of all properties) account for 42% of total hard surface area
  • Stormwater charge will be based on individualized assessments of hard surface area
  • Incentives will be offered to Large Properties
    • Applicants will have to demonstrate management of water quantity and quality
    • It is anticipated that the maximum available incentive will be 50% of the stormwater charge
