| Résumé | (disponible en anglais seulement)
Urban stormwater is estimated to account for approximately 30% of the phosphorus loading to Lake Simcoe. In addition to phosphorus, urban stormwater from
impervious surfaces can contribute sediment, hydrocarbons, and metals to local water features and urbanization can cause reduced recharge to groundwater systems. As a result, the Lake Simcoe Protection Plan (2009) calls for improvements to the
management of stormwater for both existing and future development with a goal to decrease phosphorous loadings and to minimize changes to the water balance. Improved urban stormwater management can be accomplished through several means including
retrofitting existing development with low impact development (LID) and using LID for future development projects. As a direct result of the Plan, LID implementation has increased within the watershed in recent years.
Determining the most
suitable locations for LID placement requires an understanding of the shallow subsurface including the geology and hydrogeology, as well as current land use and policy limitations. To help guide LID placement, the Shallow Subsurface Characterization
Project aims to provide an improved understanding of the shallow subsurface through the development of a GIS layer that prioritizes possible locations for LID projects within the East Holland River subwatershed. The GIS layer has been developed using
geologic and static water level data provided by the Regional Municipality of York and available through the Oak Ridges Moraine Groundwater Program.
Based on this improved understanding of the shallow subsurface environment, the final product is
a single easy-to-use GIS layer that characterizes the watershed into areas that are deemed to be of low, medium, or high priority for LID placement. This will allow for a simple desktop evaluation of the most appropriate locations for LID retrofits,
even for staff or members of the public that have limited hydrogeologic knowledge. The long term goal is for the layer to be available on the LSRCA website to municipalities, stormwater engineers, planners, students, and anyone interested in LID
within the East Holland River subwatershed. |
