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
Rosedale Ravine Lands works because its connectivity score (80) is one of the city's strongest and its natural comfort (84) is also top decile (68 transit stops sit within a 400 m walk; 84 intersections fall within 100 m of the edge).
What limits this park
Rosedale Ravine Lands's edges are fronted by border-vacuum land uses (highways, rail, parking, blank institutional), risk score 100.
Most distinctive characteristic
Most distinctive feature: exceptionally high connectivity (80, top decile).
Jacobs reading
Rosedale Ravine Lands sits between an urban social park and an ecological retreat: moderately useful for both, exceptionally suited to neither.
Tradeoffs
- The park is enclosed by buildings (80) but the surrounding streets are quiet (edge activation 0): frame without animation.
- High connectivity coexists with high border-vacuum risk (100): much of that connectivity is to highways, rail, or parking lots, not to neighbourhoods.
Typology classification
Classified as Ravine / Naturalized Park: 98% ravine overlap, 50% canopy. Secondary read: Corridor / Linear Park (shape elongation 5.8× a circle of equal area).
Edge Activation
Within 100 m of the park edge: 79 active uses (transit_stop, retail, restaurant, cafe) and 62 dead/hostile uses (rail, parking_lot, highway). 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 15 mapped paths/walkways and 148 sidewalk segments within 50 m; 84 street intersections within 100 m; 68 transit stops within a 400 m walk; 14 estimated access points across ~7,897 m of perimeter. moderate edge density, small superblock penalty applied. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity
2 distinct amenity types in the park (bench, drinking_water). 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: 50.3% estimated tree canopy; 98.2% inside the ravine system; nearest waterbody ~600 m; 65 city-mapped trees inside the polygon (4.4/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
399 buildings within 25 m of the park edge (192 mid-rise, 161 low-rise, 46 tower); avg edge height 19.0 m (~6 floors); 5.1 buildings per 100 m of 7,897 m perimeter (strong frontage density); edges are at a Jacobs-scale walkable mid-rise (3 to 7 floors); 46 towers ≥ 40 m within 25 m of the edge. "Eyes on the park" come strongest from the 192 mid-rise edge buildings.

Jacobs warned that highways, rail, parking lots and blank institutional edges act as "vacuums" that suppress foot traffic and isolate the park from its neighbourhood.

Does this score feel accurate?
Your read of Rosedale Ravine Landsmatters. We’re testing whether the model lines up with how people actually use the park. Submissions are stored locally; no account needed.
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.
- Mitigate border vacuums (highways, rail, parking) with active programming on the still-permeable edges and treat the hostile edge as a design challenge.
