Amendments to the Cleanliness Bylaw to Support Biodiversity
4 mars 2020
At its general meeting on March 3, Saint-Laurent's Council adopted amendments to the Bylaw on cleanliness. These amendments mainly pertain to the paragraphs relating to the requirements for the maintenance of vegetation, including ragweed, on private property.
"These changes may seem minor, but they are very important to us because these small adjustments to the Bylaw will meet the increasing public demands for more ecological development, while providing a balanced regulatory framework. In addition, they will allow us to more effectively control the emergence of weeds and invasive plants without sacrificing urban biodiversity.
Alan DeSousa, Mayor of Saint-Laurent
The proposed changes are intended to support biodiversity, ecological connectivity and heat island control by easing certain requirements that are considered obsolete in 2020.
The Bylaw now allows the height of grass on built land to reach 20 cm instead of 15 cm. It also makes it possible for these areas to be developed in a more natural way, including native plants. For vacant lots, maintenance of greenery will be required on a 1.2-metre wide strip along the public road or any partially built land.
In addition, in order to protect Saint-Laurent's tree heritage, the Bylaw stipulates that it is prohibited to glue, nail, staple or otherwise attach anything to a tree or shrub located on the public domain.
On all properties, noxious plants, including poison ivy and ragweed, remain prohibited in Saint-Laurent because of their negative impact on human health.
Furthermore, the Mayor of Saint-Laurent took this opportunity to announce a new awareness campaign that will begin in the spring of 2020 to counter the undesirable effects of ragweed on human health. Residents will be urged to remove ragweed from their properties by the end of July in order to prevent the spread of pollen from this noxious plant, which is the main cause of seasonal rhinitis, commonly known as hay fever, which affects 1 in 5 Quebecers. Details of this campaign will be released shortly.
