Quick Reference

Placemaking

A collaborative process of shaping public spaces to strengthen the connection between people and the places they share. Placemaking draws on community input, local assets, and creative vision to transform underutilized spaces into vibrant destinations.

Mixed-Use Development

An urban design approach that combines residential, commercial, cultural, and institutional uses within a single building, block, or neighborhood. It promotes walkability, reduces car dependence, and creates vibrant street life throughout the day.

Transit-Oriented Development (TOD)

A planning strategy that concentrates higher-density, mixed-use development within walking distance of public transit stations. TOD aims to increase ridership, reduce automobile dependency, and create compact, walkable communities.

Urban Legibility

The degree to which the physical form of a city can be easily understood and navigated by its inhabitants. Kevin Lynch identified five elements of legibility: paths, edges, districts, nodes, and landmarks.

Human Scale

The design of buildings, streets, and public spaces at proportions that feel comfortable and relatable to the human body, typically emphasizing ground-level details, moderate building heights, and narrow street widths that encourage pedestrian activity.

Complete Streets

Streets designed to enable safe access for all users, including pedestrians, cyclists, motorists, and public transit riders of all ages and abilities. They typically include sidewalks, bike lanes, transit stops, and traffic-calming features.

Tactical Urbanism

Low-cost, temporary changes to the built environment intended to improve local neighborhoods and test longer-term urban design interventions. These quick-build projects gather community feedback before permanent investment.

Figure-Ground Relationship

An analytical technique in urban design that maps the relationship between built mass (figure) and open space (ground) in a city plan. It reveals the spatial patterns, density, and urban fabric character of different neighborhoods.

Setback and Build-to Line

Regulations controlling the distance between buildings and the street. Setbacks push buildings away from the street, while build-to lines require buildings to align at the sidewalk edge, creating a continuous street wall that defines outdoor rooms.

Wayfinding

The design of environmental cues, signage systems, and spatial organization that help people navigate through complex urban environments. Effective wayfinding reduces confusion, enhances accessibility, and improves the user experience of a city.

Key Terms at a Glance

Active Frontage:Ground-floor facades with doors, windows, and engaging uses that create interaction between buildings and the street.

Adaptive Reuse:Converting existing buildings or infrastructure to new functions while preserving their physical character.

Build-to Line:A zoning regulation requiring building facades to be placed at a specific distance from the street edge.

Charrette:An intensive, collaborative design workshop bringing together stakeholders to develop urban design plans within a compressed timeframe.

Complete Streets:Streets designed to accommodate all users safely, including pedestrians, cyclists, transit riders, and motorists.

Density:The number of people, housing units, or building area per unit of land, a fundamental metric in urban design.

Desire Lines:Informal paths showing where people actually walk, often diverging from designed routes.

Enclosure Ratio:The proportion of building height to street width that creates spatial definition in the public realm.

Figure-Ground:An analytical mapping technique showing the relationship between built mass and open space in plan view.

Floor Area Ratio (FAR):The ratio of a building's total floor area to the size of its lot, used to regulate development density.

Form-Based Code:A zoning approach that regulates building form and character rather than land use.

Garden City:Ebenezer Howard's concept of self-contained communities surrounded by greenbelts combining urban and rural benefits.

Human Scale:Design proportioned to the human body, creating spaces comfortable for pedestrian experience.

Infill Development:Construction on vacant or underused parcels within already developed areas, increasing density without sprawl.

Mixed-Use Development:Integration of residential, commercial, and institutional uses within a single building, block, or neighborhood.
