Rosedale Ravine Lands scores 31.1 / 100. Strongest dimensions: enclosure / eyes on park and natural comfort. Weakest: amenity diversity (0). Border-vacuum risk is elevated (84). This score is a transparent reading of Jane Jacobs-style vitality factors — not a definitive judgment.

Scores are not bell-curved. Percentiles and expected scores provide context without changing the underlying model.
Explain this score
Where did the 31 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
- Natural comfort (82) significantly outpaces connectivity (43) — restorative but hard to reach for daily use.
- The park is enclosed by buildings (87) but the surrounding streets are quiet (edge activation 0) — frame without animation.
Typology classification
Classified as Ravine / Naturalized Park: 100% ravine overlap, 44% canopy. Secondary read: Corridor / Linear Park (shape elongation 2.7× a circle of equal area).
Edge Activation
Within 100 m of the park edge: 1 active uses (transit_stop) and 10 dead/hostile uses (highway, rail). 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 2 mapped paths/walkways and 7 sidewalk segments within 50 m; 3 street intersections within 100 m; 20 transit stops within a 400 m walk; 0 estimated access points across ~277 m of perimeter. low edge density — significant superblock penalty applied. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity
No amenities recorded — score is 0 until inventory is loaded.

Natural Comfort
Natural-comfort components for this park: 44.4% estimated tree canopy; 100.0% inside the ravine system; nearest waterbody ~611 m. Reading: ravine-cooled. Source coverage: treed_area, ravine, waterbodies. Impervious surface is approximated (Toronto's authoritative layer ships only as a raster GeoTIFF).

Enclosure / Eyes on Park
17 buildings within 25 m of the park edge (16 mid-rise, 1 low-rise, 0 tower); avg edge height 18.7 m (~6 floors); 6.1 buildings per 100 m of 277 m perimeter — strong frontage density; edges are at a Jacobs-scale walkable mid-rise (3–7 floors); no towers immediately adjacent. "Eyes on the park" come strongest from the 16 mid-rise edge buildings.

Border Vacuum Risk
Border-vacuum factors within 50 m of the park: Bloor Street East, Bloor-Danforth Line, Bloor-Danforth Line, Bloor-Danforth Line. 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.

Human activity signals
Programming, social attention, temporal rhythm, and nearby pedestrian / cycling flow. An experimental aggregate layer that complements the spatial scores — partial coverage, partial confidence.
Activity reading: pedestrian intensity 18.8/100; cycling/trail 31.3/100. The strongest signal is observed pedestrian/cycling activity. Source coverage: counters.

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.
- Add or open more entrances and improve sidewalk continuity around the park. More permeability means more spontaneous use.
- Diversify what people can do in the park — playground, washroom, water, shade, performance, sport, garden — even small additions raise this score.
- Mitigate border vacuums (highways, rail, parking) with active programming on the still-permeable edges and treat the hostile edge as a design challenge.
