What types of construction will occur during the project?
The Montgomery Place Construction Project includes restoring ditches and culverts to provide a flow path for storm water, water main replacement, lead-line connection removal and replacement, and road reconstruction. Driveways on City-owned right-of-ways will be impacted.
Why is the City proposing this project?
The Montgomery Place neighbourhood has a unique network of ditches and culverts designed for storm water management in a rural setting. Over time, the effectiveness of surface drainage has been compromised as new driveways, landscaping, and erosion altered the ROWs and contributed to basement flooding and nuisance ponding during spring snowmelt and intense rainfalls.
This proposed project will improve surface drainage by re-constructing the ditches along ROWs. The City has an opportunity to cost-effectively improve road, water, and storm water infrastructure at the same time.
What are the locations of the project?
- Dundonald Avenue: Caen Street to Currie Avenue;
- Caen Street: Dundonald Avenue to Currie Avenue;
- Lancaster Boulevard: Caen Street to Dieppe Street; and
- Ortona Street: Lancaster Boulevard to 3139 Ortona Street (south side) and 3122 Ortona Street (north side).

Why did the City select these locations for 2021-2022 construction?
The City receives complaints of flooding and damage because drainage is blocked by driveway crossings that don't have proper culverts. This project area is on the downstream end of Montgomery Place, and is a priority to fix first so that upstream water has somewhere to flow. Reconstruction of ditches in this area can also be done cost-effectively with water main replacements and road reconstruction that was already planned to improve overall infrastructure in the area. Originally, construction was scheduled for 2020 and had to be delayed to finalize cost-sharing options.
When will construction start and how long will it take?
The project is scheduled to start in August 2021. The 2021 work will include connection replacement and storm sewer installation work along Dundonald Avenue. The watermain replacement on Caen Street and Lancaster Boulevard, as well as ditch and driveway work will occur in 2022. SaskEnergy work is required prior to the City contractor starting so you will see their equipment in the area in July-August with the City contractor following at a later date.
My property hasn’t flooded. Why is a ditch and culvert being installed in the right-of-way adjacent to my property?
Driveways without culverts and right-of-ways without ditches impede the flow of storm water runoff and snow melt, and contribute to flooding and damage for upstream neighbours. This project will provide a clear path for water to flow to the new catch basin being constructed on Dundonald Avenue, thereby reducing ponding and/or flooding conditions for the drainage area.
Run-off storm water storage is also required for the neighbourhood as underground storm sewers are not installed. The ditch and culverts have been designed for similar storage compared to a residential neighbourhood with underground storm sewers.
What is the City Standard for private driveways that cross the City-owned right-of-ways in Montgomery Place?
Prior to 2021, the maximum driveway width for interior lots and corner lots with crossing(s) only on one side of their property was 20 ft (6.1 m). Corner lots with a driveway crossing on the front and side yard could have up to 32 ft (9.75 m) of crossing width. The City has adopted a new maximum driveway width for Montgomery Place in 2021. The new maximum width for driveway crossings on right-of-ways is based on lot frontage; residents may have up to 1/3 lot frontage for their driveway width if they can be in compliance with drainage requirements, City-owned trees, and other utilities. Culverts are also required as applicable.
How will my driveway be impacted?
A 300 mm PVC or concrete culvert will be installed underneath all driveways within the City's right-of-way. Impacted driveway crossings will be restored with the pre-construction material (i.e., concrete driveway will be restored with concrete) and width. Property owners that are required to cost share will have the opportunity to reduce the driveway width to lower the cost share amount.
How much will I have to pay for my driveway reconstruction?
The estimated cost of existing driveways and culverts range from $3,000 to $39,000, with an average estimated cost of approximately $10,000. Properties within the construction footprint that are expected to cost share will be contacted by a City representative in early 2021 to discuss cost-sharing amounts and agreements. Refer to Cost-Sharing Options tab for more details.
Will the trees on City of Saskatoon right-of-ways be impacted?
Of the 148 trees located on right-of-ways within the project area, at least 135 will remain. In order to save as many trees as possible, slopes of the ditches around some trees will need to be steeper than other areas to protect the trees and provide effective drainage. Refer to the Related Documents for a map of trees impacted by this project.
How steep will the newly constructed ditch be? Will it be difficult to maintain and mow the grass?
The side slopes of the ditches are 3.5H:1V or 3H:1V with the exception of some locations with trees. The regular ditch slope is blended to approximately 2H:1V (similar to the slopes on Haida Ave.) near the base of trees to preserve them throughout and after the project. Please keep in mind the steep slope sections are quite small compared to the regular slope ditch length.
How much will the project cost and how will it be funded?
The project, including drainage improvements, water main replacements, and roadway paving, is estimated to cost $3.6 million.
The Lead Water Pipe Replacement Program is funded through a cost-sharing agreement where the homeowner pays 40%. Refer to Water and Sewer Upgrades for more information.
Are drainage improvements planned for other areas in Montgomery Place in the future?
A long-term drainage plan for the Montgomery Place neighbourhood will be presented in 2022, identifying the areas proposed for future construction and timing subject to available funding.
Why are there so many driveway crossings in Montgomery Place that do not meet the standards?
Many factors occurring over decades have contributed to the current situation of driveways and landscaping. Some driveways were constructed prior to standards being in place or were constructed without a Right-of-Way Crossing permit which involves a final inspection. Some property owners may not have fully considered the impact of their driveways on their neighbours downstream. The City has not had the resources in place to continually inspect the driveways and enforce compliance. However, a new process is now in place to increase awareness of requirements and enforce permits.
Who is responsible for maintaining right-of-way drainage in Montgomery Place?
The City seeks to minimize property taxes by not assuming the responsibility and cost of activities that benefit individual property owners and/or can be carried out cost effectively by citizens. As a result, citizens have the primary responsibility for maintaining the right-of-way (ROW) area on their property, which includes mowing the grass and keeping drainage paths clear. Property owners can apply for permits to construct driveways across the ROW but must adhere to crossing standards in place to maintain drainage for their neighbours. Citizens who have driveway crossings through the ROW are responsible for ensuring that culverts are clear and that drainage is not blocked.
Because of the extent of the storm water drainage erosion in Montgomery Place, the City is restoring the flow paths based on priority areas and available funding.
Why aren’t underground storm sewers being installed instead of ditches and culverts?
The cost to install underground storm water pipes is very expensive, especially in older areas where there is other underground infrastructure. Property owners in new neighbourhoods pay for those costs through a development levy. In the past, new underground storm water pipes were included in the infrastructure proposed for Montgomery Place, to be cost-shared by citizens through a neighbourhood improvement levy. However, neighbourhood citizens rejected this proposal so the ditch and culvert system has been retained.
