Bio-retention swales are vegetated practices that temporarily store, treat and infiltrate storm water runoff. Bio-retention can be integrated into a diverse range of landscape and land uses. Storm water would be contained in designated depression areas that will hold significant quantities of water and minimal runoff will be conveyed through swales and bio swales.
A permeable pavement system filters rainwater percolating through soil on its way to surface waters and to groundwater aquifers. This important step in the natural process of water purification is bypassed when rainwater falls on impermeable pavement surfaces or roofs and is carried directly through storm drainage systems into waterways.
Water from roof will be directed into the driveways where it will be contained in the stone reservoir while it infiltrates into the undisturbed soil below. The driveway system will be designed to handle all run off from the roof, sidewalks and driveway. The driveway system will be connected to the road system, permitting back up should the need ever arise.
Permeable concrete pavers will not only be esthetically pleasing to the eye, they are also very functional for walking, wheel chairs, scooters and canes.
These pavers are designed to be Accessibility for Ontarians with Disabilities Act (AODA) and are American Disabilities Act (ADA) compliant.
Creek Side will utilize a Permeable Pavement System on the roads, driveways and parking areas, to meet storm water regulations. Permeable Pavers will reduce runoff by up to 100% and contribute to maintain the hydraulic conditions that existed prior to the development. This results in reduced downstream flows and erosion of our shorelines. Studies have shown the runoff temperatures are significantly reduced as a result of the open-graded nature of the joint fill, setting bed, base and sub-base components. Permeable pavers have many positive effect such as groundwater recharging, filtering and reducing pollutants (petroleum distillates, heavy metals, total suspended solids, etc.). Permeable pavers also reduce the air temperature surrounding the road system and reduces the water temperature providing positive environmental benefits.
Rainwater harvesting saves energy by reducing use of potable water that requires energy for treatment and transport. Some of the permeable pavement system will be utilized to permit Rain Water Harvesting. It is anticipated that 5 to 10% of the water from the roofs will be directed to Rain Water Harvesting, where it can be used as required for irrigation. Rainwater will be harvested in the area of the Clubhouse and the two entrances, and stored underground. This water will be used for irrigation, reducing the need and amount of water pumped from the ground.
Why incorporate LID?
The benefits of Low Impact Development (LID) originate from the approach of treating storm water close to its sources through mimicking natural systems. Environmental benefits are realized because LID is able to reduce storm water peak flow and volume and improve water quality. Creek Side Village will capitalize on the natural hydrology of the site for drainage features, by minimizing land and vegetation disturbance.
Through permeable paving systems, infiltration, and bio swales, the maximum amount of water is returned to the ground water that enriches the soil, maintains the wetlands and creek, while increasing the water table for future use. Through the use of rainwater harvesting, we will preserve a significant amount of the water for use around gardens, etc., reducing the need for well water.
