Zoning Density
Zoning density refers to regulations that limit the number of dwelling units or the amount of construction that can occur within a certain area, helping urban planners to control growth and shape the urban landscape.
Population Density
Population density is the number of people living per unit of area, typically per square kilometer or mile. It's a key factor in urban planning for designing services and infrastructure to accommodate the density of residents.
Setback
Setback is the minimum distance which a building or other structure must be located from a street, property line, or other feature. Setbacks are important in urban planning for aesthetic, privacy, and safety reasons.
Perviousness
Perviousness is the measure of the percentage of land area that can absorb water, such as soil, grass, and undeveloped land. It's important in urban planning for managing stormwater and reducing runoff and flooding risks.
Green Space Ratio
Green space ratio is the proportion of land within an urban area that is dedicated to parks, gardens, and other green spaces. It is key to ensuring that urban dwellers have sufficient recreational areas and that urban ecosystems can thrive.
Built-up Density
Built-up density refers to the extent of the area covered by buildings within a specific zone. This measurement helps urban planners in determining how densely populated an area is with structures and affects decisions on urban sprawl and infrastructure needs.
Building Coverage Ratio
Building coverage ratio indicates the percentage of land covered by the building footprint relative to the total land area of the property. Urban planners use it to regulate and control overbuilding and to ensure adequate light, air, and privacy.
Floor Area Ratio (FAR)
FAR is the ratio of a building's total floor area to the size of the piece of land upon which it is built. It is crucial in urban planning to control densities and match the built environment to the scale and infrastructure of the area.
Net Density
Net density is similar to gross density but excludes non-developable areas such as streets and green spaces from the total area considered. Urban planners use this to assess the intensity of residential development on the available buildable land.
Site Coverage
Site coverage refers to the proportion of a plot of land that is covered by the building itself, excluding any other structures such as driveways or pools. It influences urban density and how much open land remains for other uses.
Gross Density
Gross density refers to the total number of units, either residential or commercial, divided by the total land area, including roads, parks, and other non-developable spaces. It helps urban planners in estimating overall density and planning community services accordingly.
Job Density
Job density is the measure of jobs per unit area within a region and is used to analyze and plan for economic activity and transportation needs within urban environments.
