In British Columbia, the term Integrated Stormwater Management Planning (ISMP) has gained widespread acceptance by local governments and environmental agencies to describe a comprehensive, ecosystem-based approach to rainwater management. The purpose of an ISMP is to provide direction for future development plans and identify infrastructure needs. The goal is to balance:
In the past, stormwater management planning had a primary function to identify the infrastructure needed to service increased development. The impacts of development were given little consideration.
Today’s stormwater management planning has evolved significantly to become a comprehensive approach to also include the preservation and utilization of resources within a watershed. An ISMP is intended to balance the land use needs with the natural values and functions of the watershed.

The Ministry has developed a Guidebook for developing and implementing ISMPs. To view please follow the link: Stormwater Planning Guidebook - Chapter 9
Surrey is committed to complete ISMPs for each watershed across the city as part of Metro Vancouver’s LWMP. Below is a map identifying the numerous watersheds within the City and a list of Surrey’s active and complete ISMPs.

The Campbell Watershed "Little Campbell River" ISMP process differs from other watershed ISMPs in Surrey. Due to the large size of the Campbell Watershed a scoping study is occuring in the area to define sub-watersheds within which ISMPs can be completed.
