Walker's Creek & Beamer Creek Floodplain Mapping

We appreciate all the important feedback our team has received. If you need further clarification or your comment included a question, please contact Steve Miller, Senior Manager of Water Resources, directly at smiller@npca.ca.

Does your mapping identify street storm gutters feeding these two creeks ? do you have mapping of the City Storm Drainage that feeds these two creeks so residents can see how the area surface run off contributes to the creeks ? Parking lot and street drainage are hard surface run off areas that feed storm water to the creeks very quickly and create a storm surge, especially shopping plaza and strip mall parking lots. It is hard to imagine increases since 1989 have not significantly increased to storm surge and flood plain, let alone the increase in storm intensity.

Our property backs onto Walkers Creek between Lakeshore and Cindy at your marker 82.45 where we have lived for the last 20 years. At least once a year the lower portion of the. yard floods with approx 600mm of rainwater during a heavy downpour . Due to the ever increasing natural debris in the aging wooded area behind our yard the water cannot flow out to the Creek effectively which then turns it into a swamp. An ideal breeding location for our mosquito population.

I then ask that your recommendations regarding debris clearing at culverts be extended
to include a visual inspection and clearing of some of the more flood prone areas. I believe this simple solution would be of benefit to all and help maintain the beauty of our natural areas.

I have watched the flows of the creek bed between Richelieu Dr. and Old Oxford rd. For 33 yrs. I have lived with my house partially in the flood zone. In this study it recommends that the 2 culverts be made bigger. I agree this would help. With more intense the storms the level of the flow has been higher than I have ever seen . Last big storm it was about five inches from the top of opening of Old Oxford culvert. This is occurring a lot more now. In the past it was rare to see this. Along with this, the banks are now eroding up, at the higher elevation much faster, due to the higher water. In my opinion the Old Oxford culvert should be made deeper. My main concern is that the creek bed had eroded deeply to the point where the flow stops, into the culvert. After about 3 to 5 days after when runoff stops, the creek usually stops flowing, until it dries up or until the next heavy rainfall. This is now causing stagnate pools of water. This must also be affecting the water tables. The past 5 yrs. The Midges are now bad to the point that I can no longer open my house doors or windows without them invading inside my house. The mosquitoes are no better. In the past I had no problems with the bugs. This part of the creek needs attention from Niagara St. to Trelawne Drive. As nothing has been done since I have lived here, except a little cleanup here and there. That is fine with me. But I think its time the creek bed itself needs help to flow more constantly and fluently as it has done in the past. Maybe this will solve most of the problems.

I back onto walkers creek on Bradmon. We have lived at this home for over 20 years. The water does come up during heavy rain. But our property has never been affected by any flooding. We are very happy to have many trees between us and the creek. I do agree that if the culverts, bridges and arches were maintained with the removal of fallen trees, branches and of course leaves and garbage, that would be a huge improvement. I agree that something needs to be done at McDermid Rd. And if that means improving the whole system then as a home owner, I say, get it done. It is a beautiful part of the city to live in, so maintaining function and beauty are very important for our city.

On page 4.6 of the report, Table 4-3, sub watershed 11 has a channel slope of 9.6%. In a 164m channel that would be a fall of almost 16 m. I walk that area all the time, the fall must be less than 2 m.

Hi Susan, Chris, Peter, Robert, and Devon,

Thank you for providing such valuable feedback for this project. We look forward to discussing further at the upcoming Information Session on March 4, 2020. We hope you will join us.

There is an old natural depression, creek or pond bed in subcatchment area 4. Located parallel to Niagara St. And south of Linwell.
Whenever there is sustained or sudden rainfall this area fills with water. There is what may be a city drain that runs to the storm drain on Monarch Park Drive. The drain is insufficient and the area takes a few days to a week for the collected water to disperse or evaporate. Please contact

Has the new housing development on the west side of Niagara St, between Scott St, Linwell Rd and Maple Dr, caused any more flooding problems at this area of Walker's Creek. I went too most meetings in St. Catharines involving this project. Since the project was started in spring 2019 there has been no update about any further flooding in this area next to the housing project, would have liked an update on this area as the project is still ongoing.

We walk along Walkers Creek almost everyday from Linwell Rd. to Parnell. Currently there is a large fallen tree mostly in the creek near the walkway at Keistan and Stratcona. The culverts in this section are not in great shape. Home owners whose backyards run to the creek may need information on how to care for the waterway. We are fortunate to have such a great area to enjoy. Debris entering the creek seems to be the biggest problem along with poor maintenance of the culverts.

The entrance at Costen and Strathcona leads to a small open area next to the playground that floods extensively in spring- fall. As the standing water can create mosquito breading grounds, may I suggest you consider planting a rain garden there to help soak up the water and improve the locations native plants, insects, birds and animals?

I walk my dog daily in Walkers Creek Parkway and have checked out the culverts on a regular basis at the entrance of Costen and Strathcona. One side of the culvert is blocked by debris and the flow of water is extremely reduce. I also clear the drains on Strathcona of leaves and debris. I noticed this year that the roads at the north end of Strathcona were cleaned by the city, but I believed the south end was not. There was no evidence of the street cleaner there. So the drains regularly clog up.

I am concerned that the creek, culverts and drains are not checked often enough by the city. And with the heavy rains this year, flooding is a real concern.
