Place Types and Building Types make up the palette of built forms used to represent scenarios. The UrbanFootprint library of built form types covers a full range of potential development patterns – from mixed-use centers, to residential areas, to focused employment and industrial areas – and their component buildings.
Within the system, they are used to classify existing development and allocate growth via the scenario development process.
Place Type Menu
Place Types represent places – combinations of various buildings along with the streets, parks, and other elements of urban infrastructure that surround them. A Place Type would be used to represent, for example, the mixed-use center of a town, or development along an auto-oriented suburban retail corridor.
- Residential: the number of dwelling units per acre
- Employment: the number of employees per acre
For place types, gross residential and employment density includes acreage specific to streets, parks, and civic areas while net residential and employment density does not include that. The specific percentages used to calculate gross and net densities are shown in the Land Use Information section of the Place Type Details window.
Residential Mix describes the composition of residential land use within the place type.
- Single Family Large Lot - The percentage of housing that is single family residences on lots larger than 5500 square feet.
- Single Family Small Lot - The percentage of housing that is single family residences on lots smaller than 5500 square feet.
- Townhome - The percentage of housing that is townhomes.
- Multi-Family - The percentage of housing that are multi-family units such as apartments.
Land Use Information
Land Use Information describes the breakdown of land usable by buildings and structures and land that is not developable such as parks, streets, and civic areas. The percentages displayed in this section are related to the gross residential and employment densities shown in the Density box.
- Parcel Area - The percentage of developable land for the place type.
- Streets, parks, civic areas - The percentage of undevelopable land for the place type.
Employment mix refers to the breakdown of employment types associated with the place type. Employees are classified in the following groups:
- Retail - The retail employment category includes employees engaged in selling small quantities of merchandise to the general public.
- Office - The office employment category includes employees engaged in work that supports the production of industrial goods or services or produces non-industrial goods or services.
- Industrial - The industrial employment category refers to employees engaged in the production of components, materials, or goods for use or consumption by other industries or firms or for retail sale.
- Other - The other employment category refers to all other employees not covered in another category.
Building Type Menu
Building Types, in turn, nest within Place Types as prototypical representations of common buildings. Within a town center, for example, you would find low-rise mixed use and office buildings, as well as multifamily apartments and townhomes. Building Types themselves are comprised of buildings – real-world examples that provide the grounding for quantifying building characteristics.
Represents the density of dwelling units and employees per acre. Net residential and employment densities exclude acreage specific to streets, parks, and civic areas.
Building / Parcel Information
Building and parcel information describes the characteristics of the building type.
- Average floors - the average number of floors of the buildings comprising the building type.
- Floor area ratio - the ratio of the buildings comprising the building type's total floor area to the size of the piece of land it is built on.
- Building Coverage - the percentage of the buildings comprising the building type's building area to the size of the piece of land it is built on.
Building Use Mix
The building use mix summarizes the use of the buildings within the building type.
