Flood Risk a Good Reminder to Always be Prepared
08 June 2007
The City of Richmond is again assuring residents that the threat of flooding remains low. However, residents and property owners should be vigilant and remain prepared to respond.
River levels are expected to peak throughout the weekend. However, based on current projections, water levels are expected to be well below the level of Richmond’s extensive network of dykes. Some areas outside of Richmond dykes, such as parts of Mitchell Island, may be vulnerable to flooding, particularly at high tide. The City has issued advisory letters to property owners and residents in those areas advising them to monitor the situation carefully and be prepared for the possibility of flooding.
Richmond residents are reminded that it is always a good time to have a personal emergency preparedness plan and to be prepared to sustain your family needs for at least 72 hours in the event of a crisis. Residents concerned about the possibility of flooding are encouraged to visit the City's Flood Protection in Richmond page or pick up copies of flood preparedness brochures at City Hall and most civic facilities. Detailed information is also available at http://www.pep.bc.ca.
The City of Richmond's dykes were designed and constructed to the height well above the highest flood level ever recorded (the flood of 1894). The City is also protected by an extensive drainage system consisting of 39 pump stations holding 110 pumps.
Richmond is located far to the south of the peak snow pack run-off points. This means that the water level is considerably lower in Richmond due to the widening of the river and proximity to the ocean. This gives the water a larger distribution area, thus reducing its vertical influence on the river and the likelihood that dykes might be breached.
If any flooding occurred, it would most likely take place at high tide and remain localized until such time as the tide receded. In this case, the City would begin repairs and drainage at the earliest opportunity possible.
The City’s dykes are currently being inspected on a daily basis and river levels around Richmond are constantly measured through 24-hour electronic monitoring at four sites. The City has done some precautionary sandbagging in some areas and is prepared to mobilize a broader response on short notice should risk levels increase.
