Urban planning
Mixed-Use Development
Buildings or districts combining residential, commercial and other uses in one walkable area, reducing travel demand and supporting vibrant, compact communities.
Definition
Mixed-use development combines two or more significant uses — residential, retail, office, hospitality, civic, cultural or recreational — within a single building (vertical) or a connected district (horizontal), designed for integration, density, land-use compatibility and walkability with uninterrupted pedestrian connections (Urban Land Institute formulation).

Overview
What it means
By putting daily needs close together, mixed-use development reduces car dependence, supports local business and keeps streets active across the day. It reverses the 20th-century zoning practice of separating functions, which fuelled sprawl and long commutes.
How it is used
Planning codes enable mixed-use zoning; developers design live-work-play districts; sustainable urbanism frameworks (15-minute city, transit-oriented development) treat it as core infrastructure for low-carbon lifestyles.
Why it matters
Urban form locks in transport emissions for decades; mixed-use, compact development is one of the most durable levers for cutting mobility-related emissions and land take.
Review
Public comments appear only after editor acceptance. Draft comments stay in the review queue.
Reviewers choose the definition or an overview paragraph, leave a comment or replacement, and attach evidence or a source link.
Editors compare reviewer cards side by side. AI may help find agreement, conflicts, unsupported claims and possible source issues.
Only an editor-accepted synthesis changes the public page. Reviewer identities are shown only with consent and an editorial decision to attribute them.
Submitted reviews stay private until an editor decides whether to accept and attribute them.

Review board
Comment on a specific line. Each reviewer stays separate until an editor accepts a merged draft.
Each person comments on the definition or overview in their own draft card, with role, evidence and suggested wording kept together.
AI can compare comments against the current text, flag conflicting claims, surface missing evidence and identify where reviewers agree.
An editor merges compatible suggestions into a draft change, checks sources, records disagreements and decides what can be published.
