4.8.100 Purpose.

A transportation and parking demand management (TPDM) plan includes a wide range of strategies intended to increase walking, biking, and transit use and reduce single-occupant vehicle trips and parking demand. [Ord. NS-2289, 2017]

4.8.200 Applicability.

In compliance with BDC Chapter 4.5, Master Planning and Development Alternatives, institutional and employment master plans must develop a TPDM plan. All other development applications may choose to develop a TPDM plan. [Ord. NS-2289, 2017]

4.8.300 Preparation.

The TPDM plan must be prepared by a transportation planner, or licensed professional engineer especially qualified in civil or traffic engineering by the State of Oregon. [Ord. NS-2289, 2017]

4.8.400 Review Process.

The TPDM plan must be reviewed concurrently with an associated development application using the review procedures required for the development application. [Ord. NS-2289, 2017]

4.8.500 Submittal Requirements.

In addition to the submittal requirements of BDC Chapter 4.7, Transportation Analysis, the proposed TPDM plan must include the following information as deemed applicable by the Development Services Director:

A.    TPDM goals, objectives and policies.

B.    Proposed types and approximate number of users (e.g., residents, employees, students, customers, patients, visitors, clients, and deliveries).

C.    Anticipated mode of travel by users (vehicle, biking, walking and transit).

D.    Anticipated parking demand by time of day and/or demand by user.

E.    Anticipated parking utilizing shared spaces.

F.    Proposed number of on- and off-site parking spaces, including carpool, vanpool, car share and bike parking.

G.    Parking and trip demand analysis.

H.    Estimated daily trip generation and peak hour of trips for the proposed use based on the ITE trip generation rates (note: this may not be the p.m. peak of 4:00 to 6:00 p.m.; e.g., an institution of higher education may have a peak hour of use that is different than the p.m. peak hour).

I.    Proposed trip and parking reduction measures in BDC Table 4.8.500 according to the following requirements:

1.    A maximum trip generation reduction rate of 25 percent for the peak hour of use will be considered for combined trip reduction measures. If the TPDM plan including the applicant’s proposed trip reduction measures and rates are approved by the City, the approved trip generation reduction rates will be applied to the applicant’s Transportation Facilities Report in BDC Chapter 4.7, Transportation Analysis.

2.    A minimum of three parking reduction measures must be proposed.

3.    The number of vehicle parking spaces may be reduced up to 20 percent of the minimum requirements in BDC Table 3.3.300, Required Off-Street Vehicle Parking Spaces.

Table 4.8.500 – Trip and Parking Reduction Measures 

Facility Provision Measures

Trip Generation Reduction Rate

Parking Reduction

Project provides no more than the minimum required parking and achieves that by providing the maximum on-street parking that is permitted and/or using shared parking agreements.



Project reserves a minimum of 10% of vehicle parking spaces with designated signage for carpool, vanpool and car share vehicles, with a minimum of one space required. The carpool, vanpool and car share parking spaces must be provided free of charge and located at the most desirable on-site location.



Provide on-site showers and lockers free of charge.



Provide enclosed bike lockers and/or fenced, covered bike storage areas and/or a designated bike storage area inside a building.



Project provides twice as many covered, secured bike parking racks or facilities as required by BDC Chapter 3.3, Vehicle Parking, Loading and Bicycle Parking.



Ongoing Incentive Measures

Trip Generation Reduction Rates

Parking Reduction

Project is located within 1/4 mile of a transit facility and employer participates in CET’s Group Bus Program.



Implement a carpool, vanpool and/or car share program (e.g., carpool ride-matching for employees, assistance with vanpool formation, provision of vanpool or car share vehicles). The carpool, vanpool and car share parking spaces must be provided free of charge and located at the most desirable on-site location.



Project charges the actual cost to provide on-site parking on an annual basis for employee/student parking and provides free parking for carpool, vanpool and car share vehicles. The carpool, vanpool and car share parking spaces must be located at the most desirable on-site location.



Implement parking cash-out program for employees (nondriving employees receive transportation allowance equivalent to the value of subsidized parking).



Provide a shuttle program or participation in an existing recognized shuttle program subject to any fees for the existing program.



Flexible Scheduling – Allow employees to reduce their number of weekly commute trips and shift work trips to nonpeak hour times of day. Examples include:



• Teleworking – Allow employees to work from home or a nonoffice location one or more days a week.

• Compressed Workweek – Enable employees to compress regularly scheduled hours into fewer work days per week.

• Flexible Schedule – Allow employees to offset work hours from the typical 9-5 standard and shift commute travel to off-peak hours.

Provide unbundled parking.



Provide a bike-share program or free use of bikes on-site that is available to all tenants/employees of the site.



Provide a guaranteed ride home program.



Participation in a transportation demand management (TDM) incentive program recognized by the City (e.g., Commute Options Partner Program).



Other TPDM elements as approved by the City.

Up to 25%

Up to 20%

J.    A description of how the proposed measures will reduce the development’s trips and parking demands.

K.    A description of how the proposed measures will be achieved and maintained over the life of the project.

L.    Site plan that designates the following TPDM measures, if applicable:

1.    External. Carpool, vanpool and car share parking areas, paid parking areas, bike parking areas, and land dedicated, planned or for existing transit facilities and bus shelters.

2.    Internal. Showers/lockers, bike storage areas, information boards/kiosks and on-site support services.

M.    TPDM Plan Designated Contact. The contact is responsible for administering carpool and vanpool ride-matching services and promotional programs and updating information (e.g., transit routes and schedules; carpool, vanpool and car share information; bike lanes, routes and paths and facility information; and alternative commute subsidy information) on a board/kiosk that is located in a prominent location. The City must be provided with a current name and phone number of the designated contact.

N.    Enforcement and monitoring program. [Ord. NS-2289, 2017]

4.8.600 Approval Criteria.

A.    In addition to the approval criteria for the development application, the review authority of the development application will approve, approve with conditions or deny the TPDM plan based on all of the following criteria:

1.    The TPDM plan demonstrates that the measures provide transportation options and reduce the demand for parking; and

2.    The TPDM measures are feasible and appropriate for the project, considering the proposed use or mix of uses and the project’s location, size, and hours of operation. [Ord. NS-2289, 2017]

4.8.700 Ongoing Participation.

The applicant is required to commit to ongoing participation in the TPDM plan in its deeds, codes, covenants and restrictions and is subject to ongoing monitoring and tracking of the activities undertaken to implement the approved measures and their results. [Ord. NS-2289, 2017]

4.8.800 Modifications.

A.    Modifications to an approved TPDM plan may be processed concurrently with a Type II or Type III development application. The applicant may request to reduce the number of vehicle parking spaces more than 20 percent of the minimum requirements in BDC Table 3.3.300, Required Off-Street Vehicle Parking Spaces, if it can be demonstrated that actual demand for parking spaces during the peak period is less than 85 percent.

B.    A modification to an approved TPDM plan that is not processed concurrently with a Type II or Type III development application will be processed as an individual Type II application.

C.    The Development Services Director may elevate a Type II application for a modification to the Planning Commission for hearing as a Type III application.

D.    Modifications must meet the approval criteria in BDC 4.8.600. [Ord. NS-2289, 2017]

4.8.900 Reporting.

At the request of the City, a report documenting the TPDM plan’s activities undertaken to implement the approved measures and their results must be submitted to the Development Services Director at the responsibility of the applicant. [Ord. NS-2289, 2017]
