The Tysons area is a rapidly urbanizing community with growing transportation needs. Because of this, it is important that Transportation Demand Management in this area is held to a higher standard, especially with resources such as the Metro’s Silver Line serving the area and providing connectivity to the greater Washington, D.C., area.
Below are the Trip Reduction Goals for developments in Tysons. As Gross Square Feet (GSF) increases in the area, the reduction goals of developments are also increased. TDM Programs and plans are created to meet these reduction goals.
A Remedy Fund has been a component of recent TDM initiatives and has taken the form of a monetary set-aside that is used if the TDM measures implemented by a development are failing to achieve TDM goals. The benefit of a Remedy Fund is that it can be accessed immediately to improve a TDM program as needed. A contribution to a Remedy Fund of $.40 per square foot of commercial development and $.30 per square foot of residential development is anticipated to be established upon occupancy permit issuance for each building. If annual trip counts reveal that goals are not met, monies from the Remedy Fund must be spent, in an amount specified in Attachment II, to enhance the TDM program.
| Gross Square Feet in Tysons |
Distance from Metro Station | |||
| 0 to 1/8 Mile | 1/8 to 1/4 Mile | 1/4 to 1/2 Mile | Beyond 1/2 Mile | |
| Trip Reduction Goal | ||||
| Up to 65,000,000 | 45% | 35% | 30% | 25% |
| 65,000,000 | 50% | 40% | 35% | 30% |
| 84,000,000 | 55% | 45% | 40% | 35% |
| 90,000,000 | 58% | 48% | 43% | 38% |
| 96,000,000 | 60% | 50% | 45% | 40% |
| 105,000,000 | 63% | 53% | 48% | 43% |
| 113,000,000+ | 65% | 55% | 50% | 45% |
To help reach these goals, every TDM program in Tysons is required to contribute to their local Transportation Management Association (TMA) and set up three different funds (Incentive Fund, Remedy Fund, and Penalty Fund) each with its own purpose.
Take, for example, a new development in Tysons with 130,000 square feet of office space and 80,000 square feet of residential space.
The site developer would contribute $17,000 to the local TMA.
| Office | 130,000 * $0.10 = | $13,000 |
| Residential | 80,000 * $.0.05 = | $4,000 |
| Total | $13,000 + $4,000 = | $17,000 |
To the Incentive Fund, the developer would need to contribute $4,200.
| Office | 130,000 * $0.02 = | $2,600 |
| Residential | 80,000 * $.0.02 = | $1,600 |
| Total | $2,600 + $1,600 = | $4,200 |
To the Remedy Fund, the total amount contributed would be $76,000.
| Office | 130,000 * $0.40 = | $52,000 |
| Residential | 80,000 * $.0.30 = | $24,000 |
| Total | $52,000 + $24,000 = | $76,000 |
Finally, to the Penalty Fund, the developer would need to contribute $17,000.
| Office | 130,000 * $0.10 = | $13,000 |
| Residential | 80,000 * $.0.05 = | $4,000 |
| Total | $13,000 + $4,000 = | $17,000 |
The amounts contributed to each fund along with other requirements are outlined below:

TDM Work Plan and Annual Reports
Each TDM program is required to submit a TDM Work Plan (TDMWP), which will outline the strategies to be implemented, a timeline of when each strategy will be implemented, and provide an assessment of strategies executed to date.
The Annual Report provides a snapshot of current TDM conditions for a site. Every year this report is to be submitted with information on traffic counts, status of the buildings on the site, TDM budget, trip reduction goal progress, what work has been done to satisfy each TDM proffer, and anticipated changes in the TDM program for the upcoming year.
Although urban density in the rest of Fairfax County is not as high as in Tysons, it is still important to implement TDM measures that reduce the number of trips being generated by new developments.
The reduction goals for Non-Tysons TDM programs are as follows:
| Development | Non-Tysons TOD Locations | Non-TOD Locations (More than 1/2 Mile from Station) | ||
| 0 to 1/4 Mile from Station | 1/4 to 1/2 Mile from Station | |||
| Office | Baseline* | 30% | 25% | 20% |
| TDM Goal** | 45%-35% | 40%-30% | 35%-25% | |
| Residential | Baseline | 30% | 25% | 15%-10% |
| TDM Goal | 45%-35% | 40%-30% | 25%-15% | |
*Baseline refers to the inherent reduction from ITE trip rates observed in Fairfax County without any formal TDM program elements in place. These reductions include the following: vehicle trip reduction due to transit use, peak hour spreading and existing TDM activities (prior to a formal TDM program).
**Use of the higher end of the reduction range should be considered especially for developments in areas of high existing or planned urban accessibility, located close to and with easy and convenient pedestrian access to transit stations (<1/4 mile for rail, <1/8 mile for bus service), and in a walkable, mixed-use environment. Mixed-use development supports higher levels of vehicle trip reduction due to internal trip capture and as well as to walk and bicycle trips within the development or to adjacent developments. A project with TDM that is part of a larger mixed-use development may, therefore, support greater vehicle trip reductions than a smaller, single-use, stand-alone project that implements the same site-level TDM measures.
To help reach these goals, every Non-Tysons TDM program must set up two different funds (Incentive Fund and Remedy Fund) each with its own purpose:
Take, for example, a new Non-Tysons development with 130,000 square feet of office space and 80,000 square feet of residential space and within a ½ mile of a Metro stop.
To the Incentive Fund, the developer would need to contribute $4,200.
| Office | 130,000 * $0.02 = | $2,600 |
| Residential | 80,000 * $.0.02 = | $1,600 |
| Total | $2,600 + $1,600 = | $4,200 |
For the Remedy Fund, the total amount contributed would be $34,000.
| Office | 130,000 * $0.20 = | $26,000 |
| Residential | 80,000 * $.0.10 = | $8,000 |
| Total | $26,000 + $8,000 = | $34,000 |
