12.0 Glossary

Parcel: The basic unit of land entitlement. A designated area of land established by plat,
subdivision, or otherwise legally defined and permitted to be used or built upon. A lot, or
contiguous group of lots, in single ownership or under single control, usually considered a
unit for purposes of development.

Parcel Map: A map depicting the establishment of up to four new lots by splitting a recorded
lot. Parcel maps are subject to the California Subdivision Map Act and a city’s subdivision
regulations.

Parks, Park Land, Parkland: Open space lands whose primary purpose is recreation. Land
that is publicly owned or controlled for the purpose of providing parks, recreation, or open
space for public use.

Parking Area, Public: An open area, excluding a street or other public way, used for the
parking of automobiles and available to the public, whether for free or for compensation.

Parking Management: An evolving TDM technique designed to obtain maximum utilization
from a limited number of parking spaces. Can involve pricing and preferential treatment for
high occupancy vehicles, non-peak period users, and short-term users.

Parking Ratio: The number of parking spaces provided per 1,000 square of floor area (e.g.,
2:1 or “two per thousand”).

Parking, Shared: A public or private parking area used jointly by two or more uses.

Parking Space, Compact: A parking space (usually 7.5 feet wide by 16 feet long when
perpendicular to a driveway or aisle) permitted in some localities on the assumption that
many modern cars are significantly smaller, and require less room, than a standard
automobile. A standard parking space, when perpendicular to a driveway or aisle, is usually
8.5 feet wide by 18 feet long.

Parkway: An expressway or freeway designed for non-commercial traffic only; usually
located within a strip of landscaped park or natural vegetation.

Parkway Strip: A piece of land located between the rear of a curb and the front of a sidewalk,
usually used for planting low ground cover and/or street trees, also known as "planter strip."

Particulate Matter: Any material except uncombined water which exists in a finely divided
form and is a liquid or solid at standard conditions. The size of particulate matter can vary
from coarse, wind-blown dust particles to fine particle combustion products.

Particulate Matter, Fine (PM2.5): PM2.5 is a mixture of very small particulates with an
aerodynamic diameter equal to or less than 2.5 microns. PM2.5 consists of particles directly
emitted into the air and particulates formed in the air from the chemical transformation of
gaseous pollutants. PM2.5 particulates are emitted from activities such as industrial and
residential combustion, and from vehicle exhaust. Particles 2.5 microns or smaller infiltrate
the deepest portions of the lungs, increasing the risks of long-term disease, including chronic
respiratory disease, cancer, and increased and premature death.
