A: Prior to 2002, the only people contributing to the maintenance and development of the system were the property owners within the Holland Marsh. In 2002 a Section 76 Drainage Engineer’s Report was developed to determine if the assessment area could be expanded. The report determined that the lands within the Holland Marsh Watershed in BWG, King, Newmarket, East Gwillimbury, New Tecumseth and Caledon, all eventually drain into the Holland Marsh Drainage System.
