The Floodplain Mapping Agreement

The Floodplain Mapping Program was delivered under the Canada/British Columbia Agreement Respecting Floodplain Mapping. Signed in December 1987, the agreement marked an acceleration of a provincial mapping program which commenced in 1974. Following is a summary of the objectives of the agreement.

The Agreement:

  • restricted both governments from further undertakings (including construction of, or a major addition to, structures or a change in the use of land) in areas that are vulnerable to flooding and are located in designated floodplains;
  • discouraged financial assistance for development of undertakings in flood-prone areas;
  • accommodated measures to encourage local authorities to restrict undertakings in flood-prone areas under their jurisdiction; and
  • required adequate floodproofing measures to have been incorporated into new development in a floodplain after designation to be eligible for disaster assistance.

An Amending Agreement was signed in August 1994. Following are highlights of the Amending Agreement.

  • recognized the need to ensure the continued effectiveness of the floodplain mapping program and contribute towards integrated water resource management,
  • provided additional funding to March 31, 1998 to phase down the program in British Columbia by completing a number of the high priority projects,
  • allowd for a review of the existing floodplain mapping projects to maintain their adequacy, accuracy and usefulness,
  • terminated the Agreement on the 31st day of March 2003.
