The TMSAMS Study resulted in the production of Station Access Manage Plans for each station. The effort was led by the Fairfax County Department of Transportation (FCDOT), was guided by a diverse 16 member HMSAMS Advisory Group, was supported by a consultant team and included three public workshops as well as an interactive, online survey. The HMSAMS public outreach process resulted in the participation of approximately 275 Fairfax County or Town of Herndon residents. The HMSAMS Final Report, completed in September of 2014 and presented to the Fairfax County Board of Supervisors Transportation Committee on January 20th, 2015, details the entire HMSAMS process and serves as the Access Management Plans for the future Herndon and Innovation Center Metrorail Stations, including recommended bicycle and pedestrian infrastructure projects for each station area.

In January of 2014, the Fairfax County Board of Supervisors (BOS) approved a transportation program including $1.4 billion in funding for transportation projects, spread out over the next six years. This six-year transportation program included approximately $21 million dedicated to HMSAMS projects. Now that the HMSAMS study is complete, FCDOT staff will use the HMSAMS Final Report as one of a variety of tools to make bicycle and pedestrian project funding recommendations to the BOS. Once these project funding recommendations have been approved by the BOS, FCDOT staff can move forward with the design phase of the highest priority HMSAMS projects.
