The DHS Headquarters Consolidation at St. Elizabeths TRANSPORTATION MANAGEMENT PROGRAM December 4, 2008 I. EXECUTIVE SUMMARY This document outlines the Transportation Management Program (TMP) for the planned Department of Homeland Security (DHS) Headquarters Consolidation at the St. Elizabeths Campus in Washington D.C. A TMP is required as part of a federal agency’s planning submission for undertaking any project that will increase the employment level on a worksite to 100 or more employees (including existing and proposed employees). A TMP is an employer’s active program to foster more efficient employee commuting patterns. The plan includes specific strategies to encourage change in employee travel mode, trip timing, frequency and length, and travel routes so as to reduce traffic congestion and improve air quality. A TMP also offers the benefit of reduced demand for parking spaces. This TMP serves as an Appendix to the separate St. Elizabeths Master Plan report and has been prepared pursuant to the National Capital Planning Commission (NCPC) requirements. The Master Plan creates a vision for the development of the St. Elizabeths Campus. Several conceptual Master Plan alternatives were developed and analyzed as part of the Final Environmental Impact Statement (FEIS). One preferred build-out Master Plan alternative, Alternative 5, is included in this TMP. This alternative builds on the assets of the existing campus, allowing for the rehabilitation and reuse of existing buildings. The alternative has a build-out year of 2016 and will provide accommodations for 14,000 employees with approximately 4.5 million gross square feet (GSF) including administrative and operations space and shared
