Carpool means two to six persons traveling together in a single vehicle.

Development project means any nonresidential or mixed-use project which requires discretionary approval by the city.

Director means the director of community development or the designee of the director of community development.

Employee means any person employed by a firm, person, business, educational institution, nonprofit agency or corporation, government agency or other entity, or combination of such entities, which collectively employs 100 or more persons at a single worksite. "Employee" shall include persons employed on a full-time, part-time or temporary basis.

Employer means any person, firm, business, educational institution, government agency, nonprofit agency or corporation, or other entity, or combination of such entities, which employs or houses tenants that collectively employ 100 or more employees at a single worksite within the city on a full- and/or part-time/temporary basis, and may either be a property owner or tenant of a development project.

Improvement plans means plans submitted to the city as part of an application for a building permit for the enlargement or expansion of new, existing, or change of use (as defined by the Uniform Building Code) of any nonresidential building or use.

Minimum building size means the total gross leaseable floor area measured in square feet of a building or group of buildings at a common work location. The term includes the total floor area of both new and existing facilities.

Mixed-use development means the development of a parcel(s) or structure(s) with two or more different land uses such as, but not limited to, a combination of residential, office, commercial retail, public or entertainment in a single or physically integrated group of structures.

Transportation demand management means the implementation of programs, plans or policies designed to encourage changes in individual travel behavior. Transportation demand management can include an emphasis on alternative travel modes to the single occupant vehicle such as carpools, vanpools and transit; on the reduction or elimination of the number of vehicle trips, or shifts in the time of vehicle commutes to other than the peak period.

Trip reduction means reducing the number of work-related trips taken during peak-period hours in single occupant vehicles.

Vanpool means a van occupied by seven or more persons traveling together.

Worksite means a building or group of buildings which are in actual physical contact or separated solely by a private roadway or easement and which are owned or operated by an employer.

Sec. 12.20.050. - TDM-facility design program.

As a condition of approval of any development project covered by the provisions of this chapter, the approving authority shall require the preparation, adoption, and compliance with a TDM-facility design program which will encourage increased ridesharing and alternative transportation modes, applicable to the specific development project. The components of a TDM-facility design program may include any of the following standards and such other TDM-facility strategies as may be appropriate to encourage and facilitate TDM opportunities or related air quality requirements:

(1) Carpool/vanpool parking. A percentage of parking spaces, located as close as is practical to each entrance of the use such spaces are intended to serve or at other preferential locations within the employee parking area, may be reserved for use by carpool and vanpool vehicles, as determined by the approving authority.

These spaces may be reserved and designated for carpool/vanpool parking by marking such spaces "Carpool Only."

(2) Bicycle parking. An area where bicycle racks shall be provided for use by employees and tenants who commute to the site by bicycle may be designated. The bicycle parking area may be established in a secure location and be in close proximity to employee entrances.

(3) Transit waiting shelters. Transit waiting shelters, including bus pullouts, bus pads and rights-of-way for bus shelters, may be required by the city in consultation with the county transportation authority, for development projects located along high traffic volume streets and established or proposed bus routes. The applicability of this subsection (3) shall be determined in conformance with standard traffic engineering principals including, but not limited to, the frequency and relative impact of blocked traffic due to stopped buses and the level of transit ridership at the location.

(4) Pedestrian access. Sidewalks and other paved pathways may be provided on site to connect off-site external pedestrian circulation systems (planned or existing) to the building site. Sidewalk locations may integrate existing and planned waiting shelters with building entrances.

(5) Bicycle access. Implementation of the city's master plan of bike trails may be integrated with project review, to provision continuity and transition to existing and planned on-street and off-street bike trails.

(6) Joint access and shared parking. For applicable developments designed as a worksite, provision of joint access and shared parking across multiple parcels may be incorporated into project design to facilitate integration of TDM facility strategies.

(7) Miscellaneous optional requirements. The following additional TDM mechanisms may be incorporated into the project design, taking into consideration project use(s), size and building site layout:

a. A commuter information area, located within the central building, to provide employees with information on alternative transportation modes. This area shall be centrally located and accessible to all employees or tenants and shall be of sufficient size to provide and display information on alternative transportation modes, such as current maps, routes and schedules for public transit.

b. Shower and locker facilities on site for use by employees or tenants who commute to the site by bicycle or walking.

c. Rideshare vehicle passenger loading and unloading areas to provide employees who vanpool or carpool to embark and disembark from rideshare vehicles, to and from the building site. The design and location of such loading areas shall consider on-site circulation characteristics, pedestrian access, and building site entrances to provide for employee access.

d. On-site daycare facilities.

e. On-site lunch rooms/cafeterias.

f. On-site commercial services such as banks, restaurants, and small retail uses.

g. Parking spaces designated for park-and-ride users.
