Herder Drive Rehabilitation
This long-term project investigates and corrects the root causes of the roadway issues along Herder Drive and in Hewlett Park. The issues included:
- Pot holes
- Road heaves
- Higher than normal water levels
The investigation revealed the problems that were causing the poor conditions on Herder Drive:
At the Erickson Drive storm water crossing: This drainage route was too small and created a bottle neck
Along the drainage channels from Erickson Drive to Hewlett Park: The drainage channel was too flat. Water was standing instead of draining away
At the storm water mains within the roadways of Hewlett Park: The mains were too shallow and were too small to allow enough drainage
With groundwater conditions in the area: Because of 1 - 3, the water had nowhere to drain
How?
First, we corrected the problems causing poor conditions (1 - 3 above)
Next we repaired Hunter Road and Hinshaw Drive
Work continues to repair Herder Drive and then Harrison Road
Many projects were coordinated at the same time to maximize efficiency
What?
We improved surface and ground water drainage so that water moves from west to east, away from Hewlett Park. Improvements include:
Added the Hampton Pointe storm water lift station and new Hampton Pointe outfall
Regrading of drainage ditches and storm ponds
Added two large concrete box culverts at the Erickson Drive storm water crossing. The new culverts eliminate the bottleneck at the Erickson Drive storm water crossing. The old culverts were about 60 cm in diameter. The new box culverts are 1.6 meters tall and 2.9 meters wide
Improved roadways:
- Stronger road structure
- Safer roadway for driving
Improved sightlines for pedestrians to cross roadway safely
Removal, replacement and upgrading the existing storm water mains
Installation of weeping tile drains along the roadway
Removal of concrete in areas where the ground settled, and the surface water is not draining properly
Removal and replacement of the asphalt roadway
Addition of traffic calming measures
Where?
Herder Drive rehabilitation takes place in phases, from:
Hinshaw Drive to Hagerman Road
Hagerman Road to Harrison Road
Harrison Road to 47 Avenue
