Curb Level is a term used in zoning regulations to refer to the height of the street or sidewalk in relation to the building height and setback controls in non-contextual and manufacturing districts. This measurement affects how buildings look, how they are accessed, and how they interact with the surrounding area. (nyc.gov, 2023)
In many urban areas, zoning regulations specify a maximum height for buildings that is based on the Curb Level. This means that buildings cannot exceed a certain height in relation to the street or sidewalk. This height restriction can help to ensure that buildings are in scale with their surroundings and do not overwhelm the street or sidewalk.
Curb Level can also affect how buildings are accessed. For example, in areas with high Levels, buildings can require stairs or ramps to provide access to the entrance. In areas with lower Curb Levels, buildings may be able to have direct access from the street or sidewalk. (NYC Planning, 2021)
Zoning regulations may specify different Curb Levels for different types of buildings or areas. In areas with high Curb Levels, buildings may be set back from the street or sidewalk to provide space for landscaping or other features. In areas with lower Curb Levels, buildings may be closer to the street or sidewalk, which can create a more urban feel. For example, a commercial district may have a higher Curb Level than a residential district, to create a distinction between different types of areas.
