Any potential impacts could be mitigated through surveys, monitoring, and recordation.

Impacts on Vegetation and Soils
Analysis
As discussed for the action alternatives, vegetation could be changed as a result of constructing underground structures. Trees or shrubs removed or lost during construction would be replaced in kind with stock from an NPS nursery or other cooperating horticultural institutions; however, the plants would likely be smaller than existing vegetation. Some trees would be permanently lost and not replaced. Damage to commemorative trees would be avoided where possible.

space. However, 2,000 square feet of space under West Executive Avenue could be used to store more frequently used items. Spaces in the White House now used for storage could be returned to more appropriate uses. The proposed storage area would replace existing uses within the basement level of the Office Thrift Supervision. A space utilization study would be undertaken in conjunction with OTS building management to determine where current uses could be relocated.

ENVIRONMENTAL CONSEQUENCES
Conclusion
* Meeting space would be farther from the West Wing.
* As described for the proposed plan and alternative 1, 290 spaces would be provided under Pennsylvania Avenue for motorcades, diplomatic and business visitors, and senior staff. Staff parking for an additional X50 vehicles would be provided by (1) adding 200 parking spaces either under Pennsylvania Avenue (with access by way of a tunnel from the Office of Thrift Supervision) or at the Office of Thrift Supervision, and (2) providing 650 other spaces within a 10 minute walk of the White House complex, either in leased facilities or a new federal parking garage. Offsite spaces could be perceived as being farther away and less safe.
* Deliveries through the Office of Thrift Supervision would require additional security measures.

Additional traffic congestion as a result of E Street being closed could make nearby office space less attractive to tenants.
