This story is based on the results of a 2016 study, using 2014 data, done for the Edmonton area to determine the vulnerable drainage and sewage areas of Edmonton in regards to a 1 in 100 year rainfall event.
Due to the constant changing of subsurface infrastructure (adding, upgrading, etc.) combined with the constant changing definition of a 1 in 100 year rainfall event (based on historic rainfall amounts), this raster file reflects the results of a study done in 2016 and should neither suggest previous year’s vulnerabilities nor future year’s vulnerabilities.
For a more regional Edmonton area breakdown of the Study’s results:
There are three different colour to the vulnerability of the roadways and the corresponding ponding depth that would occur for that area during a large rainstorm.
Those colours are:
Green (representing the depth from surface that sanitary flows can surcharge from less than 2.5 m)
Yellow (representing the depth from surface that sanitary flows can surcharge from 1.5 to 2.5 m)
Red (representing the depth from surface that sanitary flows can surcharge from greater than 1.5 m)
Yellow (representing the depth from surface that sanitary flows can surcharge from 1.5 to 2.5 m)
Red (representing the depth from surface that sanitary flows can surcharge from greater than 1.5 m)
This Raster file is best viewed overlaid with the 2016 Flood Mitigation Study - Drainage and Sanitation Surcharge Map; as the various coloured areas follow the subsurface infrastructure (and the corresponding roadways if you are also viewing the street map as a layer).

This dataset is based on 2014 information and will not be updated further. The model is based on a theoretical, worst-case scenario storm that has never occurred in the Edmonton area.
Model Accuracy:
The LiDar used was a 5 meter grid system. LiDar has an accuracy of ? cm horizontally/vertically. Bare Earth LiDar was used in for this model surface.

The 100 year flood was based on the 2015 Edmonton 4 year Chicago storm event over 20 plus neighbourhoods. The data is a collection of the worst case scenario of model runs.
This is a common practice for Edmonton drainage models. These models are high level concept and projects determined from this data set will undergo finer, more detailed modeling.
These maps are a visual representation and intended to be used when prioritization of the best engineering solutions that are scheduled to be brought forward to Utility Council to mitigate future flooding in the City. The best engineering solutions are high level concept designs and require further modeling and design. At the time of the PDF release, November 9, 2016 there was no funding for any projects to be completed or for further design. Strategy will be brought forward to Utility Committee on June 7, 2017. Council will be determining funding and rate of project completion.

This map is a representation of each depth layers in the Surface Ponding map from the 2014 Flood Mitigation Study.
This map representation was created as a result of a 2013 to 2016 study done for the Edmonton area to determine the vulnerable areas of Edmonton in regards to a 1 in 100 year rainfall event.
Due to the constant changing of subsurface infrastructure (adding, upgrading, etc.) combined with the constant changing definition of a 1 in 100 year rainfall event (based on historic rainfall amounts), this raster file reflects the results of a study done in 2016 and should neither suggest previous year’s vulnerabilities nor future year’s vulnerabilities.
There are four different colours to show the depth of water that might pool on the ground during a large rainstorm.
Those colours are:
Green (representing a ponding depth from 0.00 - 0.35 m)
Yellow (representing a ponding depth from 0.35 - 0.50 m)
Orange (representing a ponding depth from 0.50 to 0.75 m)
Red (representing a ponding depth greater than 0.75 m)
Yellow (representing a ponding depth from 0.35 - 0.50 m)
Orange (representing a ponding depth from 0.50 to 0.75 m)
Red (representing a ponding depth greater than 0.75 m)

The 100 year flood was based on the 2015 Edmonton 4 year Chicago storm event over 20 plus neighbourhoods. The data is a collection of the worst case scenario of model runs.
This is a common practice for Edmonton drainage models. These models are high level concept and projects determined from this data set will undergo finer, more detailed modeling.
These maps are a visual representation and intended to be used when prioritization of the best engineering solutions that are scheduled to be brought forward to Utility Council to mitigate future flooding in the City. The best engineering solutions are high level concept designs and require further modeling and design. At the time of the PDF release, November 9, 2016 there was no funding for any projects to be completed or for further design. Strategy will be brought forward to Utility Committee on June 7, 2017. Council will be determining funding and rate of project completion.

The depth layer that this spatial data represents is the 0.35 m to 0.50 m Surface Ponding Depth (Orange) layer.
This raster file was created as a result of a 2013 to 2016 study done for the Edmonton area to determine the vulnerable areas of Edmonton in regards to a 1 in 100 year rainfall event.
Due to the constant changing of subsurface infrastructure (adding, upgrading, etc.) combined with the constant changing definition of a 1 in 100 year rainfall event (based on historic rainfall amounts), this raster file reflects the results of a study done in 2016 and should neither suggest previous year’s vulnerabilities nor future year’s vulnerabilities.
There are four different colours to show the depth of water that might pool on the ground during a large rainstorm.
Those colours are:
Green (representing a ponding depth from 0.00 - 0.35 m)
Yellow (representing a ponding depth from 0.35 - 0.50 m)
Orange (representing a ponding depth from 0.50 to 0.75 m)
Red (representing a ponding depth greater than 0.75 m)
Yellow (representing a ponding depth from 0.35 - 0.50 m)
Orange (representing a ponding depth from 0.50 to 0.75 m)
Red (representing a ponding depth greater than 0.75 m)

This dataset is based on 2014 information and will not be updated further. The model is based on a theoretical, worst-case scenario storm that has never occurred in the Edmonton area.
Model Accuracy:
For Areas west and central Digital Elevation Model was used from 2004. For the rest of the areas Bare Earth LiDar data was used. The surface data used was set to a horizontal resolution of 2.5 meters with a grid cell of 5m by 5m. This puts the vertical resolution at an accuracy of 0.1 meters.

This raster file was created as a result of a 2016 study, using 2014 data, done for the Edmonton area to determine the vulnerable drainage and sewage areas of Edmonton in regards to a 1 in 100 year rainfall event.
Due to the constant changing of subsurface infrastructure (adding, upgrading, etc.) combined with the constant changing definition of a 1 in 100 year rainfall event (based on historic rainfall amounts), this raster file reflects the results of a study done in 2016 and should neither suggest previous year’s vulnerabilities nor future year’s vulnerabilities.
For a more regional Edmonton area breakdown of the Study’s results:
There are three different colour to the vulnerability of the roadways and the corresponding ponding depth that would occur for that area during a large rainstorm.
Those colours are:
Green (representing the depth from surface that sanitary flows can surcharge from less than 2.5 m)
Yellow (representing the depth from surface that sanitary flows can surcharge from 1.5 to 2.5 m)
Red (representing the depth from surface that sanitary flows can surcharge from greater than 1.5 m)
Yellow (representing the depth from surface that sanitary flows can surcharge from 1.5 to 2.5 m)
Red (representing the depth from surface that sanitary flows can surcharge from greater than 1.5 m)
This Raster file is best viewed overlaid with the 2016 Flood Mitigation Study - Drainage and Sanitation Surcharge Map; as the various coloured areas follow the subsurface infrastructure (and the corresponding roadways if you are also viewing the street map as a layer).
