Explain this score
Where did the 60 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
- Strong physical conditions (score 60) but weak observed activity signals (9) — the model says this should work, but events, mentions, and counters say it isn't being used at the level the urban form would predict.
- High connectivity (74) coexists with little programming evidence — easy to reach, but no recurring civic life detected.
Performance in context
- This park is a strong overperformer for its cohort — raw 60 versus an expected 36 for similar parks (medium Ravine / Naturalized Park ravine) (gap +24).
Typology classification
Classified as Ravine / Naturalized Park: 100% ravine overlap, 89% canopy. Secondary read: Corridor / Linear Park (shape elongation 2.5× a circle of equal area).
Edge Activation
Within 100 m of the park edge: 14 active uses (retail, transit_stop) and 2 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 10 mapped paths/walkways and 34 sidewalk segments within 50 m; 22 street intersections within 100 m; 44 transit stops within a 400 m walk; 5 estimated access points across ~1,562 m of perimeter. moderate edge density — small superblock penalty applied. Source coverage: centreline, pedestrian_network, transit_osm.

Natural Comfort
Natural-comfort components for this park: 88.5% estimated tree canopy; 100.0% inside the ravine system; nearest waterbody ~725 m; 6 city-mapped trees inside the polygon (1.9/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
85 buildings within 25 m of the park edge (29 mid-rise, 45 low-rise, 11 tower); avg edge height 16.5 m (~6 floors); 5.4 buildings per 100 m of 1,562 m perimeter — strong frontage density; edges are at a Jacobs-scale walkable mid-rise (3–7 floors); 11 towers ≥ 40 m within 25 m of the edge. "Eyes on the park" come strongest from the 29 mid-rise edge buildings.
