The indicated flood limit may be exceeded and portions of the floodplain can flood more frequently. The delineation of the flood plain is estimated by the BC Ministry of Sustainable Resource Management and the Drainage Section of the City of Surrey. Updates are made whenever possible & modeled.所标注的洪水限值可能被突破，部分洪泛区的洪水发生频率亦将有所提升。本次洪泛区的划定工作由不列颠哥伦比亚省（British Columbia）可持续资源管理部与素里市排水科负责估算完成。相关划定结果将在条件允许时进行更新，并将通过建模手段完成校验与推演。
