GTAA Living City Project
Integration Etobicoke Creek and Implementation
Watershed
Living City Project as an interdisciplinary approach
to watershed management within this area of the
Etobicoke and Spring creeks.
The GTAA Living City Project is a major undertaking
involving four main components:
1. Terrestrial Natural Heritage
The Terrestrial System inventory and
modeling for the study area (LBPIA Wildlife
Control Area) includes management
recommendations, identification of
potential/targeted natural cover and priority
restoration and enhancement sites to meet
TRCA’s local, as well as watershed, targets
for the terrestrial system.
2. Aquatic Ecosystems
The Etobicoke Creek Watershed Fisheries
Management Plan (FMP) presents
management recommendations for target
species at a subwatershed scale and
restoration opportunities for priority aquatic
habitat in close proximity to GTAA lands.
3. Stormwater Management
The Stormwater Management Study
includes five components: A Modelling
Assessment of Runoff Water Quality
Management in Etobicoke Creek for
Catchment 219, which is a representative
catchment upstream of the GTAA property;
the Etobicoke Creek Watershed Spills
Mapping Study; a Fluvial Geomorphology
and Erosion Assessment of Etobicoke
Creek; off-site and on-site stormwater
management opportunities, and the TRCA
Hydrology Model Update. These reports
provide the basis for improved stormwater
controls in the watershed.
4. Integration and Priority Implementation
Recommendations
Key recommendations from the above
studies are spatially and conceptually
integrated to ensure land uses,
water quality, fisheries and terrestrial
opportunities are prioritized within the
study area. Potential partnerships and
community outreach opportunities for
implementation are provided as part of the
Business Stewardship Program.
Study Areas
The study areas for each component provide
multiple scales of addressing watershed
management, as seen on Map 1. The Fisheries
Management Plan (FMP) takes a watershed-wide
scale in its recommendations, the Terrestrial Natural
Heritage Report provides recommendations
centered upon the GTAA study area 1* and the
Stormwater Management Report looks at upstream
catchments draining into GTAA lands. While these
study areas may vary, their impact follows a process
to realize watershed-wide targets.
