Stream 2 – Flood Mapping
Flood Mapping Coverage for High-Risk Communities
Total Project Value: $1,000,000
Federal funding: $500,000; Water Security Agency funding: $500,000
Project Start Date: June 26, 2019 (1-year project)
This project will provide flood mapping to a number of communities known to be at high risk of suffering recurrent flood damages. This pilot project will fulfill several learning objectives for the Water Security Agency (WSA) that will build their capacity to design and implement a provincial long-term flood risk identification and mitigation program. Additionally, Light Detection and Radar (LiDAR) data will be collected for all 20 identified communities, including Regina, Saskatoon, and Moose Jaw. Updated maps will allow these cities to make better decisions about future development and existing flood risks. The 20 communities identified constitute a population of 588,870, which is almost half of the total population of the province.
1-500 Year Flood Mapping – North Saskatchewan River, Prince Albert
Total Project Value: $120,000
Federal funding: $60,000; City of Prince Albert funding: $60,000
Project Start Date: May 22, 2019 (1-year project)
This project will complete a river hydraulics model to update the flood mapping for the City of Prince Albert in a three-phased approach. There are four different neighbourhoods and over 2000 properties that lie within the 1:500 year floodplain in Prince Albert. This project will provide updated data models to more accurately reflect the risk of flood events in the future. This data can be utilized for the development of infill neighbourhoods and to update design standards for new neighbourhoods in Prince Albert.
Stream 2 – Flood Mapping
City of Saskatoon Flood Mapping with Updated Intensity Duration Frequency (IDF) Curves
Total Project Value: $212,377.69
Federal funding: $100,647.18; City of Saskatoon funding: $111,730.51
Project Start Date: August 21, 2018 (2-year project)
The City of Saskatoon has partnered with the University of Saskatchewan and Concordia University to update the city-wide urban flood maps and its design standards by consolidating and applying new Intensity Duration Frequency (IDF) curves that incorporate climate change risks. LiDAR data will be obtained for new and developing neighborhoods for use in modeling and flood map updates and urban flood zones will be mapped for various storm events and risk levels. This project will also determine what changes to the storm water infrastructure design is needed with the application of the new IDF curves. Expected costs of flooding and expected costs to implement different storm water design standards to address climate change risks will be assessed.
Stream 2 – Flood Mapping – Completed Project
Flood Hazard Mapping of Priority Communities in Saskatchewan
Total Project Value: $141,000
Federal funding: $70,500; Rural Municipality of Corman Park No. 344 funding: $70,500
Project Dates: January 16, 2018 – March 31, 2019
This project created updated flood hazard mapping for Corman Park, the most populated rural municipality in Saskatchewan, which has been subject to historical flooding and flood damages and has been identified as vulnerable to regulatory flood events. This project provided more comprehensive information to guide land use planning and decision-making on infrastructure investments, enhancing resiliency and adaptive capacity for changing climates. Through updated flood hazard mapping, the municipality can ensure development planning avoids higher risk areas, new structures are built to standard in lower-risk flood areas, and existing high-risk structures can be enhanced to flood protection standards. This project also helps improve community emergency preparedness and flood response.
Stream 1 – Risk Assessments – Completed Project
Saskatchewan Flood and Natural Hazard Risk Assessment
Total Project Value: $190,617.96
Federal funding: $95,308.98; Province of Saskatchewan funding: $95,308.98
Project Dates: November 1, 2016 – May 31, 2018
This project resulted in the creation of Saskatchewan’s first comprehensive flood and natural hazard risk assessment report. The risk assessment report helps to inform priority risk reduction strategies and hazard mitigation measures, such as the need for additional floodplain mapping, mitigation planning and structural works.
