Explain this score
Where did the 43 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
- A modest overperformer for its ravine / naturalized park typology (+7 vs the median in medium Ravine / Naturalized Park ravine).
Typology classification
Classified as Ravine / Naturalized Park: 97% ravine overlap, 2% canopy. Secondary read: Neighbourhood Park (3.5 ha, framed by 0 mid-rise vs 0 towers).
Edge Activation
Within 100 m of the park edge: 3 active uses (transit_stop) and 1 dead/hostile uses (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 3 mapped paths/walkways and 17 sidewalk segments within 50 m; 4 street intersections within 100 m; 11 transit stops within a 400 m walk; 4 estimated access points across ~910 m of perimeter. low edge density — significant superblock penalty applied. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity
2 distinct amenity types in the park (sports_field, washroom). 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: 1.7% estimated tree canopy; 96.5% inside the ravine system; nearest waterbody ~52 m; 7 city-mapped trees inside the polygon (2.0/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
107 buildings within 25 m of the park edge (0 mid-rise, 107 low-rise, 0 tower); avg edge height 4.1 m (~1 floors); 11.8 buildings per 100 m of 910 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
Border-vacuum factors within 50 m of the park: 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.

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.
- Increase canopy and reduce paved area. Shade and water features extend usable hours and seasons.
