Explain this score
Where did the 41 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
Tradeoffs
- The park is enclosed by buildings (60) but the surrounding streets are quiet (edge activation 0) — frame without animation.
Performance in context
- A modest overperformer for its ravine / naturalized park typology (+8 vs the median in small Ravine / Naturalized Park ravine).
Typology classification
Classified as Ravine / Naturalized Park: 80% ravine overlap, 0% canopy
Edge Activation
Within 100 m of the park edge: 0 active uses (none) and 0 dead/hostile uses (none). 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 9 sidewalk segments within 50 m; 5 street intersections within 100 m; 12 transit stops within a 400 m walk; 2 estimated access points across ~479 m of perimeter. edge density is healthy — no superblock penalty. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity
2 distinct amenity types in the park (fitness, playground). Diversity, not raw count, drives the score so a park with many distinct activity types can outrank a larger park that repeats the same use.

Natural Comfort
Natural-comfort components for this park: ~11.9% effective canopy (0.0% from contiguous tree polygons + scattered tree density); 79.5% inside the ravine system; nearest waterbody ~99 m; 17 city-mapped trees inside the polygon (17.0/ha). Reading: ravine-cooled. Source coverage: ravine, waterbodies, street_trees. Impervious surface is approximated (Toronto's authoritative layer ships only as a raster GeoTIFF).

Enclosure / Eyes on Park
72 buildings within 25 m of the park edge (0 mid-rise, 72 low-rise, 0 tower); avg edge height 4.5 m (~2 floors); 15.0 buildings per 100 m of 479 m perimeter — strong frontage density; edges are barely there or single-storey; no towers immediately adjacent. "Eyes on the park" come strongest from the 0 mid-rise edge buildings.

Border Vacuum Risk
Park edges face the city — no significant border vacuum detected.

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.
