Founded on British Columbia case study experience, and published by the BC Ministry of Water, Land and Air Protection in 2002, Stormwater Planning: A Guidebook for British Columbia formalized a science-based understanding to set performance targets for reducing rainwater runoff volumes and rates. These targets represent the synthesis of biological and hydrological understanding. The Guidebook is structured to meet the information needs of different audiences.
Integrated Rainwater Mgmt Planning
In British Columbia, the term Integrated Stormwater Management Planning (ISMP) has gained widespread acceptance by local governments and the environmental agencies to describe a comprehensive, ecosystem-based approach to rainwater management. In the Greater Vancouver region, one of the primary results of a co-ordinated approach has been the creation of a template for ISMPs, which are watershed- specific, flexible and adaptive strategies.
The Greater Vancouver Regional District (GVRD) – commissioned a research project to create “Stormwater Source Controls Design Guidelines 2005”. The objective of this project was to promote effective implementation of rainwater source controls in the Georgia Basin region of British Columbia.

Rainwater Management in British Columbia: Performance Target Methodology at heart of Provincial Guidebook
“The widespread changes in thinking about rainwater runoff impacts that began in the late 1990s reflected new insights in two areas: hydrology; and aquatic ecology. These new insights were the result of improved understanding of the causes-and-effects of changes in hydrology brought about by urban development, and the consequences for aquatic ecology,” explains Peter Law.

Township of Langley is the latest municipality to become part of the Water Balance Model Partnership
All the major municipalities on the south side of the Fraser River are now partners in the Water Balance Model initiative, namely: Langley Township, Delta, Surrey, Abbotsford and Chilliwack.
Capitalizing on the enthusiasm and early momentum generated by the Okotoks Conference in September 2004, a number of Alberta agencies have come together to form the Alberta Low Impact Develpoment Partnership. The initiative is co-chaired by the cities of Calgary and Edmonton.
The Department of Fisheries and Oceans is one of three federal agencies that is a Water Balance Model partner. Use of this web-based decision support and scenario modeling tool will enable development project proponents to show how they can achieve stream protection objectives.
