Scores are not bell-curved. Percentiles and expected scores provide context without changing the underlying model.
Explain this score
Where did the 25 come from? Each weighted contribution against a neutral 50 baseline. Green = pushed up; red = pulled down.
Sum of contributions = the headline score. A negative bar means that dimension dragged the park below the city-wide neutral baseline.
Why this park works
What limits this park
Most distinctive characteristic
Jacobs reading
Performance in context
- Reads as a modest underperformer relative to comparable parks (gap -9; cohort: very large Ravine / Naturalized Park ravine).
Typology classification
Classified as Ravine / Naturalized Park: 92% ravine overlap, 24% canopy. Secondary read: Waterfront Park (nearest waterbody within ~0 m).
Edge Activation
Within 100 m of the park edge: 7 active uses (transit_stop) and 30 dead/hostile uses (highway, parking_lot). Active edges keep "eyes on the park" through the day; parking lots, blank institutional walls, rail and highway frontages drain street life.

Connectivity
Connectivity blends paths, intersections, transit, entrances, and edge density. This park has 4 mapped paths/walkways and 23 sidewalk segments within 50 m; 12 street intersections within 100 m; 24 transit stops within a 400 m walk; 5 estimated access points across ~3,558 m of perimeter. low edge density — significant superblock penalty applied. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity

Natural Comfort
Natural-comfort components for this park: 23.7% estimated tree canopy; 91.6% inside the ravine system; 3.3% water surface; 16 city-mapped trees inside the polygon (0.5/ha). Reading: ravine-cooled. Source coverage: treed_area, ravine, waterbodies, street_trees. Impervious surface is approximated (Toronto's authoritative layer ships only as a raster GeoTIFF).

Enclosure / Eyes on Park
19 buildings within 25 m of the park edge (7 mid-rise, 7 low-rise, 5 tower); avg edge height 24.3 m (~8 floors); 0.5 buildings per 100 m of 3,558 m perimeter — thin frontage — significant blank-edge share; edges lean tall but still framed; 5 towers ≥ 40 m within 25 m of the edge. "Eyes on the park" come strongest from the 7 mid-rise edge buildings.

Border Vacuum Risk
Border-vacuum factors within 50 m of the park: Highway 401 Collector, Highway 401 Collector, parking_lot, parking_lot, parking_lot, parking_lot, parking_lot, Highway 401 Collector, parking_lot, parking_lot, parking_lot, parking_lot, parking_lot, Highway 401 Collector, Highway 401 Collector, parking_lot. Jacobs warned that highways, rail, parking lots and blank institutional edges act as "vacuums" — they suppress foot traffic and isolate the park from its neighbourhood.

Tell us how this park feels
We measure structure (canopy, edges, connectivity). You measure feeling. Both matter — and disagreement is itself useful civic data.
What would improve this park?
Generated from the weakest measured dimensions — a starting point, not a prescription.
- Activate the edges: encourage cafés, retail or community uses on the streets that face the park; replace blank or parking-lot edges where possible.
- Diversify what people can do in the park — playground, washroom, water, shade, performance, sport, garden — even small additions raise this score.
- Encourage mid-rise, windowed frontages around the park so residents have direct sightlines onto it.
- Mitigate border vacuums (highways, rail, parking) with active programming on the still-permeable edges and treat the hostile edge as a design challenge.
