Transportation demand management

LT4.1 | Possible point

Intent

To reduce pollution and land development impacts from automobile use for commuting.

To reduce pollution and land development impacts from automobile use for commuting.

To reduce energy consumption, pollution from motor vehicles, and adverse public health effects by encouraging multimodal travel.

To encourage transit use and reduce driving by providing safe, convenient, and comfortable transit waiting areas and safe and secure bicycle storage facilities for transit users.

To reduce energy consumption, pollution, and harm to human health from motor vehicles by encouraging multimodal travel.

Requirements

Reduce the number of commuting round trips made by regular building occupants using single occupant, conventionally powered and conventionally fueled vehicles. For the purposes of this credit, alternative transportation includes at a minimum, telecommuting; compressed workweeks; mass transit; rideshare options1; human-powered conveyances; carpools; vanpools; and low-emitting, fuel-efficient2 or alternative-fuel vehicles; walking or bicycling.

Performance calculations are made relative to a baseline case that assumes all regular occupants commute alone in conventional automobiles. The calculations must account for seasonal variations in the use of alternative commuting methods and, where possible, indicate the distribution of commuting trips using each type of alternative transportation.

Points are earned for reductions in conventional commuting trips during the performance period according to the following schedule:

For all projects

Earn one point for every two options achieved below, for a maximum of two points. For the purposes of this credit, existing buildings and their occupants are exempt from the requirements.

Option 1. TDM program

Create and implement a comprehensive transportation demand management (TDM) program for the project that reduces weekday peak-period motor vehicle trips by at least 20% compared with a baseline case, and fund the program for a minimum of three years following build-out of the project. The TDM program must be prepared by a qualified transportation professional. Any trip reduction effects of Options 2, 3, 4, or 5 may not be included in calculating the 20% threshold.

OR

Option 2. Transit passes

Provide transit passes valid for at least one year, subsidized to be half of regular price or cheaper, to each occupant locating within the project during the first three years of project occupancy (or longer). Publicize the availability of subsidized transit passes are available to project occupants;

Option 3. Developer-sponsored transit

Provide year-round, developer-sponsored private transit service (with vans, shuttles, buses) from at least one central point in the project to other major transit facilities, and/or other destinations such as a retail or employment center, with service no less frequent than 45 daily weekday trips and 30 daily weekend trips. The service must begin by the time the project total floor area is 20% occupied and must be guaranteed for at least three years beyond project build-out. Twenty percent occupancy is defined as residents living in 20% of the dwelling units and/or employees working in 20% of the total nonresidential floor area.

Provide transit stop shelters and bicycle racks adequate to meet projected demand but no less than one shelter and one bicycle rack at each transit stop. Shelters must be covered, be at least partially enclosed to buffer wind and rain, and have seating and illumination. Bicycle racks must have a two-point support system for locking the frame and wheels and must be securely affixed to the ground or a building. Any alternative to bicycle racks must ensure bikes will be stored safely and access to these bikes must be convenient for visitors and customers.

Option 4. Vehicle sharing

Locate the project such that 50% of the dwelling units and nonresidential building entrances are within a 1/4 mile (400 meters) walk distance of at least one vehicle in a vehicle-sharing program. For each vehicle, dedicate one parking space accessible to vehicle-sharing members. Through signage and other means, publicize to project occupants the availability and benefits of the vehicle-sharing program. If the project has more than 100 dwelling units and/or employees and has a minimum transit service of 60 daily weekday trips and 40 daily weekend trips, at least one additional vehicle and parking space for every 100 dwelling units and/or employees must be available. If the project has more than 100 dwelling units and/or employees but does not have transit service at the frequencies specified above, at least one additional vehicle and parking space for every 200 dwelling units and/or employees must be available. Where new vehicle locations are created, a vehicle sharing program must begin by the time the project total floor area is 20% occupied; commit to providing vehicles to the locations for at least two years. Twenty percent occupancy is defined as residents living in 20% of the project dwelling units and/or employees working in 20% of the total nonresidential floor area of the project.

Option 5. Unbundling of parking

For 90% of multiunit residential units and/or nonresidential floor area, the associated parking spaces are sold or rented separately from the dwelling units and/or nonresidential floor area.

Work with the transit agency or agencies serving the project to identify transit stop locations within and/or bordering the project boundary where transit agency-approved shelters and any other agency-required improvements, including bicycle racks, will be installed no later than construction of 50% of total project floor area. At those locations, install approved shelters and any required improvements, or provide funding to the transit agency for their installation. Shelters must be covered, be at least partially enclosed to buffer wind and rain, and have seating and illumination. Any required bicycle racks must have a two-point support system for locking the frame and wheels and be securely affixed to the ground or a building. Any alternative to bicycle racks must ensure bikes will be stored safely and access to these bikes must be convenient for visitors and customers.

AND

Work with the transit agency or agencies serving the project to identify locations within and bordering the project boundary where the agency determines that transit stops will be warranted within two years of project completion, either because of increased ridership on existing service resulting from the project or because of planned future transit. At those locations, reserve space for transit shelters and any required improvements, including bicycle racks. In lieu of or in addition to new stops, this requirement can be satisfied with a commitment from the transit agency to provide increased service to the transit stops that will have been installed at the time of 50% build-out.

Work with the transit agency or agencies serving the project to provide kiosks, bulletin boards, and/or signs that display transit schedules and route information at each public transit stop within and bordering the project.

Achieve at least two of the following options.

Earn 1 point for every two options, for a maximum of 2 points. For the purposes of this credit, existing buildings and their occupants are exempt from the requirements.

Option 1. Transit passes

Provide transit passes valid for at least one year, subsidized to 100% of regular price, to each resident and employee locating within the project during at least the first three years of project occupancy. Publicize the availability of subsidized transit passes to project occupants.

AND/OR

Option 2. Developer-sponsored transit

Provide year-round, developer-sponsored transit service (vans, shuttles, buses) from at least one central point in the project to other major transit facilities or retail or employment centers, with service no less frequent than 45 daily weekday trips and 30 daily weekend trips. The service must begin by the time the project’s total floor area is 20% occupied and must be guaranteed for at least three years beyond project build-out. The occupancy requirement is met when residents are living in 20% of the dwelling units and/or employees are working in 20% of the total nonresidential floor area.

Provide transit stop shelters and bicycle racks adequate to meet projected demand but no less than one shelter and one bicycle rack at each transit stop. Shelters must be covered, be at least partially enclosed to buffer wind and rain, and have seating and illumination. Bicycle racks must have a two-point support system for locking the frame and wheels and must be securely affixed to the ground or a building.

Option 3. Vehicle sharing

Locate the project such that 50% of the dwelling units and nonresidential use entrances are within a ¼-mile (400-meter) walking distance of at least one vehicle in a vehicle-sharing program, as specified below, depending on project size.

  • If the project has fewer than 100 dwelling units and/or employees, provide one vehicle.
  • If the project has more than 100 dwelling units and/or employees and has a minimum transit service of 60 daily weekday trips and 40 daily weekend trips, provide at least one additional vehicle and parking space for every 100 dwelling units and/or employees.
  • If the project has more than 100 dwelling units and/or employees but does not have transit service at the frequencies specified above, provide at least one additional vehicle and parking space for every 200 dwelling units and/or employees.

For each vehicle, dedicate one parking space accessible to vehicle-sharing members. Publicize to project occupants the availability and benefits of the vehicle-sharing program. Commit to providing vehicles to the locations for at least two years. If a new vehicle-sharing location is planned , the vehicle-sharing program must begin by the time the project’s total floor area is 20% occupied. The occupancy requirement is met when residents are living in 20% of the dwelling units and/or employees are working in 20% of the total nonresidential floor area.

Option 4. Unbundling of parking and parking fees

For 90% of multi-unit dwelling units and/or nonresidential floor area, the associated off-street parking spaces must be sold or rented separately from the dwelling units or nonresidential floor area.

Set parking fees within the project boundary for all off-street parking equal to or greater than the cost of monthly usage for municipal public transit. Off-street parking in this instance does not include parking devoted to individual, detached residential units.

Option 5. Guaranteed ride home program

All major employers within the project must commit to providing a guaranteed ride home program for employees. A major employer accounts for more than 25% of the workers on the project site. The pro-gram must provide free rides to employees who have carpooled, taken transit, walked, or cycled to work but must leave because of an unexpected personal emergency. Rides may be on taxis, company cars, or rental cars.

Option 6. Flexible work arrangements

All major employers within the project must commit to promoting and supporting flexible work arrangements with the goal of reducing vehicle trips during peak commuting hours. A major employer accounts for more than 25% of the workers on the project site. The employer must develop internal policies that outline the terms under which employees can engage in telework, flextime, compressed work weeks, staggered shifts, or other arrangements. These policies must also describe how the program will be promoted to employees.
