Urban Planning Models & Settlement Forms

← Back to Domain-Specific Families

Abstractions about historical models for organizing urban and suburban growth — planned neighborhood and infrastructure frameworks (neighbourhood unit, green infrastructure), and settlement-morphology patterns such as ribbon development, the sector model and the urban transect.

5 abstractions in this family — domain-specific abstractions that sit near one another in structural-signature space (k-means over structural-signature embeddings). Each is shown with its short description.

• Green infrastructure — Plan and manage a connected network of natural, semi-natural, and engineered green-blue spaces to deliver stormwater, heat, biodiversity, recreation, health, and other ecosystem services across scales.
• Neighbourhood unit — Clarence Perry's residential planning model organizing a population around a walkable elementary school and internal civic spaces, bounded by arterial roads and served by local streets and shops.
• Ribbon Development — A linear settlement-growth morphology in which buildings accumulate frontage-by-frontage along an existing road, rail line, canal, coast, or ridge instead of consolidating into a compact urban fabric.
• Sector Model — Hoyt's monocentric urban-land-use model in which established residential-rent and functional districts persist directionally as wedge-shaped sectors extending outward from the center, commonly along transport and amenity axes.
• Transect (urban) — An urban-planning model arranging zones along a rural-to-urban intensity gradient so form standards vary coherently with context.
