Derrydowns Park scores 51.2 / 100. Strongest dimensions: natural comfort and connectivity. Weakest: amenity diversity (11.9). Border-vacuum risk is low. This score is a transparent reading of Jane Jacobs-style vitality factors — not a definitive judgment.

Explain this score
Where did the 51 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 51) 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 (72) 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 51 versus an expected 35 for similar parks (very large Waterfront Park waterfront) (gap +17).
Typology classification
Classified as Waterfront Park: 6% water surface inside park. Secondary read: Ravine / Naturalized Park (99% ravine overlap, 71% canopy).
Edge Activation
Within 100 m of the park edge: 11 active uses (transit_stop) and 4 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 13 mapped paths/walkways and 79 sidewalk segments within 50 m; 23 street intersections within 100 m; 37 transit stops within a 400 m walk; 12 estimated access points across ~5,148 m of perimeter. low edge density — significant superblock penalty applied. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity
1 distinct amenity types in the park (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: 71.2% estimated tree canopy; 99.0% inside the ravine system; 6.1% water surface; 80 city-mapped trees inside the polygon (2.9/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
389 buildings within 25 m of the park edge (13 mid-rise, 374 low-rise, 2 tower); avg edge height 5.5 m (~2 floors); 7.6 buildings per 100 m of 5,148 m perimeter — strong frontage density; edges are barely there or single-storey; 2 towers ≥ 40 m within 25 m of the edge. "Eyes on the park" come strongest from the 13 mid-rise edge buildings.

Border Vacuum Risk
Border-vacuum factors within 50 m of the park: parking_lot, 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.
