Glossary of Planning Terms Flashcards
Acre, gross
Area of a site calculated to the centerline of bounding streets and other public rights-of-way
Acre, gross developable
Area of a site, including proposed public streets and other proposed rights-of-way but excluding areas subject to physical or environmental constraints, which include creek corridors and floodways, and areas to be dedicated for greenways or habitat protection
Acre, net
Area of a site excluding land to be dedicated for required easements for vehicles and rights of way, either public or private; land dedicated to be hazardous or unbuildable; and land to be dedicated for public use (schools, parks, etc.)
Affordable housing
Housing capable of being purchased or rented by a household of extremely low, very low, low, or moderate income, based on the household’s ability to make monthly payments. Housing is considered affordable when a household pays less than 30% of its gross monthly income (GMI) for the housing, including utilities
Attainment area
An area determined to have met federal or state air quality standards, as defined by the federal Clean Air Act or the California Clean Air Act. An area may be an attainment area for one-pollutant and a non-attainment area for others
Best Management Practices (BMP)
The combination of standards, procedures, conservation measures, and management practices that reduces or avoids adverse impacts of development. BMPs most commonly refer to water supply and quality management, but may also refer to other resources or planning concerns, such as air quality, agriculture and soils, biological resources, etc.
Buffer area
A landscape area, usually containing trees, shrubs, and other natural surfaces, used to protect a resource such as a waterway or agricultural land, or to increase the compatibility of adjacent land uses
Buildout
That level of development characterized by full occupancy of all developable sites in accordance with the General Plan; the maximum probable level of development envisioned by the General Plan under specified assumptions about densities and intensities. Buildout does not necessarily assume parcels are developed at maximum allowable intensities
Capital Improvement Program (CIP)
The multi-year scheduling of public physical improvements based on studies of fiscal resources available and the choice of specific improvements to be constructed
Climate Action Plan (CAP)
A plan to address community, agency, or business contributions to greenhouse gas emissions (GHGs) and global climate change. A CAP usually consists of an existing GHG inventory, a projection of future emissions, a prioritized list of potential relevant actions the jurisdiction could take to reduce existing and future GHG emissions, some quantification of costs and benefits of each action, an estimate of the overall effect of plan implementation in terms of GHG reductions, and an implementation program including responsible parties, funding sources, and timelines for implementation
CNEL (Community Noise Equivalent Level)
The average equivalent A-weighted sound level during a 24-hour day, obtained after addition of five decibels to sound levels in the evening from 7pm to 10pm and after addition of 10 decibels to sound levels in the night from 10pm to 7 am.
Compatible
Capable of existing together without conflict or ill effects
Conservation
The management of natural resources to prevent waste, destruction, or neglect
Consistent
Free from variation or contradiction. Programs in the General Plan are to be consistent, not contradictory. State law requires consistency between a general plan and implementation measures such as the zoning ordinance
Curb cut
The opening along the curb line at which point vehicles or other wheeled forms of transportation may enter or leave the roadway. Curb cuts are essential at street corners for wheelchair users
dBA
The “A-weighted” scale for measuring sound in decibels; weights or reduces the effects of low and high frequencies in order to stimulate human hearing. Every increase of 10 dBA doubles the perceived loudness though the noise is actually 10 times more intense
Decibel (dB)
A unit of measurement used to express the relative intensity of sound as heard by the human ear describing the amplitude of sound, equal to 20 times the logarithm to the base 10 of the radio of the pressure of the sound measured to the reference pressure, which is 20 micropascals (20 micronewtons per square meter)
Dedication
The commitment by an owner or developer of private land for public use, and the acceptance of land for such use by the governmental agency having jurisdiction over the public function for which it will be used. Dedications for roads, parks, school sites, or other public uses often are required by the City as conditions of approval on a development.
Dedication, in lieu of
Cash payments may be required of an owner of developer as a substitute for dedication of land, usually calculated in dollars per lot, and referred to as in lieu fees or in lieu contributions
Density, Residential
The number of dwelling units per acre of land. Densities are usually expressed in units per gross developable area
Density bonus
The allocation of development rights that allow a parcel to accommodate additional square footage or additional residential units beyond the maximum for which the parcel is zoned, usually in exchange for the provision or preservation of an amity at the same site or at another location.
Detention area
A detention area is an area in the natural environment where rainwater runoff and stormwater naturally collects during a rain and then is pumped to other areas. Human activity and construction of homes have the effect of changing the size and shape of a detention area
Detention basin/pond
Facilities classified according to the broad function they serve, such as storage, diversion, or detention. Detention facilities are constructed to retard flood runoff and minimize the effects of floods
Developer
An individual who, or business which, prepares raw land for the construction of buildings or builds or causes to be built physical building space for use primarily by others, and in which the preparation of the land or the creation of building space is in itself a business and is not incidental to another business or activity
