The Agriculture Water Demand Model was developed to provide information on current and future agriculture water demands for the Okanagan Basin in the context of rapid population growth, drought from climate change and overall increased water demand. The Model has also since been used in other BC watersheds.

The intent of the model is to help fulfil the province’s commitment under the Living Water Strategy to reserve water for agricultural lands. The model calculates water use on a property-by-property basis and sums each property to obtain a total for the entire basin or sub-basins. Crop, irrigation system type, soils and climate data are used to calculate the water demand. Lands within the Agriculture Land Reserve were included in the project.

The following reports are available from the BC Ministry of Agriculture:

Here also is a short video introducing the Model when it was a finalist for the 2009/2010 Premier’s Awards.

Within the First National Engineering Vulnerability Assessment, the Public Infrastructure Engineering Vulnerability Committee (PIEVC) identified stormwater and wastewater among the four priority classes of infrastructure to assess for vulnerability and adaptability to climate change.

Here is a case study that looks at risks for the Vancouver Sewage Area’s collection system and wastewater treatment facilities in the coming decades, taking into account regional projections for increased rainfall, more intense rainfall events, sea level rise, winds and storm surge.

This Guide is designed to assist elected officials and staff to plan and act in ways that will make their communities more resilient to the impacts of a changing climate.

Part 1 introduces climate change adaptation including climate change impacts in BC, how local governments are affected, the adaptation process, and building adaptive capacity and resilience. Part 2 offers practical examples of climate change adaptation strategies in the context of land use planning, emergency management planning, long term financing and reporting, asset management, infrastructure, civic buildings policy, building regulation, watershed management, liquid waste management, air quality, biodiversity, conservation, community and economic development, legal liability and insurance. Supplemental materials include three adaptation scenarios, checklists for local governments and links to other adaptation projects and resources.

The Guide was developed under the BC Regional Adaptation Collaborative and funded by Natural Resources Canada and the Fraser Basin Council, with support from the BC Ministry of Community, Sport and Cultural Development.

The Water Conservation Calculator is a free, web-based decision support tool designed primarily for water managers in small to medium-sized communities in British Columbia. A user who has compiled the community water system data can test a variety of water conservation strategies. The outcomes can be measured, and reports and charts generated, to show how water conservation measures can save both money and water. This tool can help communities fulfill the requirements of some provincial capital grant programs.

The purpose of this study is to determine if Low Impact Development (LID) can effectively mitigate flooding under projected climate scenarios. LID relies on run-off management measures that seek to control rainwater volume at the source by reducing imperviousness and retaining, infiltrating and reusing rainwater.

In general, the simulations suggest that if future extreme rainfall events follow the median climate change projection, then LID can be used to maintain or reduce flood hazard for rainfall events up to the 25-year return period. This study demonstrates that in a smaller urban watershed, LID can play an important role in reducing the flood impacts associated with climate change

Design for the Rainfall Spectrum: Green infrastructure should be designed to perform in all three tiers of the rainfall spectrum: small (including showers), large (annual storms), and extreme (rare occurrences). This video is part of a series which provides an introduction to living with climate change on the BC Coast.

Streets & Surface Parking: Adding green infrastructure to streets can increase water quality and reduce the volume of runoff entering stormwater pipes. Rainfall can take natural pathways through the soil to support groundwater and ecosystems. This video is part of a series which provides an introduction to living with climate change on the BC Coast.

In British Columbia, climate change is expected to bring more intense short duration storms and increased runoff from roof and pavement. To adapt to climate change, we need to increase the use of low impact green infrastructure across our urbanizing watersheds. This video is part of a series which provides an introduction to living with climate change on the BC Coast.

This case study describes how the Okanagan Basin Water Board and various partners initiated the Okanagan Water Demand and Supply project to support water planning, allocation, licensing and engineering decisions in the Okanagan system. The project developed science–based computer models of the water demand and supply systems in the basin, taking into account the impacts of climate change, population growth and land use. This project received funding from the BC Regional Adaptation Collaborative program. Project materials include a summary report, local government guide, online viewer to access the data and a related video tutorial.

2014 - Institute for Catastrophic Loss Reduction

Local governments are confronting one of the most important issues of our time – the alarming recent increase in damage to homes from extreme rainfall. Communities large and small across Canada are now taking action to reduce the risk of basement flooding and damage to property from sewer backup. This book describes 20 of the many successful local projects underway in communities that are adapting to better address the risks associated with extreme rainfall.

This book recognizes and acknowledges local leadership in addressing the risk of basement flooding. Mini case studies showcase successful local actions that can and should be used by communities across the country to confront the dual challenge of waste and stormwater management. The local policy decisions presented in this report are scientifically sound and provide a sustainable foundation for long-term success.

About ReTooling for Climate Change

The ReTooling for Climate Change website is a project of the Fraser Basin Council to support local governments and First Nations in BC in preparing for climate change adaptation. The site is funded through the BC Regional Adaptation Collaborative (BC RAC), a partnership program of the Fraser Basin Council and the BC Ministry of Environment – Climate Action Secretariat, with funding from Natural Resources Canada and other in-kind contributions.
