Stormwater

Wet ponds, also known as retention ponds, are designed to manage stormwater and are typically classified into two categories: quantity ponds and quality ponds.

Quantity wet ponds are used to temporarily store stormwater during heavy rainfall to prevent flooding and erosion in downstream areas. By slowly releasing water into nearby waterways, they help maintain natural flow rates and protect surrounding ecosystems and infrastructure.

Quality wet ponds focus on improving water quality. As stormwater collects in the pond, suspended solids, organic matter, and inorganic pollutants gradually settle to the bottom. This natural filtration process mitigates the environmental impact on downstream water bodies and helps preserve natural habitats.

Dry ponds, also known as detention ponds, are shallow, grassy basins that remain dry under normal conditions. They are designed to temporarily store stormwater, allowing time for sediments and pollutants to settle out before the water is gradually released into nearby waterways.

This slow release helps improve water quality and is especially effective in managing high peak flows, reducing the risk of flooding, and minimizing potential impacts on human health and the environment.

Wetlands are shallow, vegetated areas with a broad surface area, making them highly effective for natural stormwater treatment. They remove pollutants through biological uptake and filtration by vegetation, helping to improve water quality before it reaches downstream ecosystems.

Although wetlands do not provide the same level of flood control as wet or dry ponds, they are excellent for enhancing water quality and are often used alongside quantity ponds to provide additional environmental benefits.

Stormwater ponds are components of urban drainage systems. Traditionally maintained for aesthetic purposes, storm ponds are increasingly being naturalized to enhance ecological value, improve water quality, and reduce maintenance costs. The Town has implemented a no-mowing policy allowing for storm pond blocks to naturalize and provide for environmental sustainability.

The no-mowing policy applies to designated buffer zones within storm pond blocks. These areas are intentionally allowed to grow with native grasses, sedges, and wildflowers.

Mowing only takes place along trails that had been incorporated into the original storm pond design or where needed for inspection.

Periodic selective maintenance is allowed for invasive species management.

 Yes, ticks can be present in natural areas around stormwater management ponds.

 It is not permitted to garden around stormwater ponds.  This area is maintained by the Town with the purpose of managing stormwater. The vegetation planted in these areas is focused on erosion control, water quality, and habitat for wildlife. 

 Oftentimes when conducting maintenance or construction on storm ponds it's required that they are drained and dewatered. 

 Fish are collected through a scientific survey study and the process is monitored by the Ministry of Natural Resources (MNR).

Residents can support the Town’s stormwater management efforts by taking the following preventative actions:

• Use lawn and garden chemicals responsibly
• Create a rain or stone garden
• Install a rain barrel
• Keep storm drains clear
• Be mindful of property changes

Every small effort plays a meaningful role in supporting the long-term success of the Town’s stormwater management system.
