noise level during a 24-hour day, measured in measured in decibels, and adjusted to account for the greater intrusiveness of noise generated at night.

Daylighting: The redirection of a stream into an above-ground channel. Daylighting is intended to improve the riparian environment for a stream, which had been previously diverted into a culvert, pipe, or a drainage system.

Decibel (dB): A unit measuring the magnitude of a sound, equal to the logarithm of the ratio of the intensity of the sound to the intensity of an arbitrarily chosen standard sound, specifically a sound just barely audible to an unimpaired human ear. For environmental noise from aircraft and other transportation sources, an A-weighted sound level (abbreviated dBA) is normally used. The A-weighting scale adjusts the values of different sound frequencies to approximate the auditory sensitivity of the human ear.

Density: The number of residential dwelling units per acre of land.

Desalination: The removal of salts from saline water to provide fresh water.

Developer: An individual or business that prepares raw land for the construction of buildings 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 the building space is in itself a business and is not incidental to another business or activity.

Development, existing: Includes those buildings, structures, and uses present within the Baylands during the 2010 baseline year.

Development, new: Refers to the buildings, structures, and uses proposed under each of the scenarios, including the total amount of new building area.

Development, total: means the total amount of building area proposed under each of the Project site development scenarios.

Development Agreement: A contractual agreement between a developer and the City that clearly establishes the developer's responsibility to provide a certain type of development, streets and sewer improvements, and any other mutually agreed to terms and responsibilities as a precondition for securing approval of a project.

Development Impact Fees: A fee or charge imposed on developers to pay for a jurisdiction’s costs of providing services to new development.
