Why this park works

Summerlea Park works because its amenity diversity score (40) is one of the city's strongest and its natural comfort (68) is also top quartile.

What limits this park

Summerlea Park is held back by enclosure (39, bottom quartile).

Most distinctive characteristic

Most distinctive feature: exceptionally high amenity diversity (40, top decile).

Jacobs reading

Summerlea Park is an ecological retreat. The urban-vitality numbers are low because the park exists outside the everyday city. That's the point of it.

Performance in context

  • A modest overperformer for its waterfront park typology (+9 vs the median in large Waterfront Park waterfront).

Typology classification

confidence 85%
Waterfront Parkalso reads as Ravine / Naturalized Park

Classified as Waterfront Park: 14% water surface inside park. Secondary read: Ravine / Naturalized Park (100% ravine overlap, 20% canopy).

Edge Activation

25% weightpartial 60%
18.0 / 100

Within 100 m of the park edge: 6 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 blends paths, intersections, transit, entrances, and edge density. This park has 11 mapped paths/walkways and 46 sidewalk segments within 50 m; 8 street intersections within 100 m; 16 transit stops within a 400 m walk; 10 estimated access points across ~3,496 m of perimeter. low edge density, significant superblock penalty applied. Source coverage: centreline, pedestrian_network, transit_osm.

Amenity Diversity

20% weightmeasured 75%
39.8 / 100

5 distinct amenity types in the park (basketball, playground, sports_field, tennis, 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.

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" that 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.

Rate this park on as many dimensions as you have an opinion about. 1 = not at all, 5 = strongly. Skip the ones you don't feel sure about. Aggregated only, no comments stored at the row level.

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.
  • Encourage mid-rise, windowed frontages around the park so residents have direct sightlines onto it.
