* A 290-space parking facility for motorcades, diplomats, and senior staff under Pennsylvania Avenue would be immediately accessible to the White House, would protect visitors, staff, and drivers from inclement weather, and would facilitate the staging of motorcades.
* An 850-space parking facility beneath the Ellipse would provide direct, secure access to the complex 24 hours a day (an 8- to 10-minute walk), protection from inclement weather, and the elimination of theft and damage that has occurred to cars parked on Ellipse roadways. Staff would cross E Street either at 17th Street or use the pedestrian underpass from the visitor center (the underpass would mix staff and public use, which could be inconvenient for some staff members). So that proposed actions on the Ellipse could be implemented in the early phases of the plan, surface parking on the Ellipse would be removed during the first phase of implementation.

Impacts on Access and Circulation
Analysis
* To ensure that an LOS E on H Street would not be exceeded during the morning, fewer than 100 vehicles during the peak hour should use the NEOB entrance.
* Because the 17th Street / State Place / New York Avenue intersection operates at LOS E and F during morning and afternoon rush hours, traffic would enter the garage by way of West Executive Avenue from E Street and would exit to the west on State Place (which would operate as a one-way street westbound).
ENVIRONMENTAL CONSEQUENCES
* The basic geometry along the two blocks consists of four 11' lanes within a curb-to-curb width of 44'. The south curb line of the 1600 block within President's Park would be slightly realigned. Along the south side of the 1700 block outside President's Park approximately 12' of sidewalk and 16 metered parking spaces would need to he removed to accommodate two additional traffic lanes. West of 18th Street the existing curb-to-curb width on E Street is adequate for channeling the one-way eastbound traffic to meet the proposed geometry at the 18th Street / E Street intersection.
* The north curbline in the 1700 block would be retained to minimize pavement reconstruction and the removal of trees in front of the United Unions building and the Corcoran Art Gallery. It would also match the projection of the north curbline in the 1600 block.
* Removing the sidewalk and parking meters on the south side of the 1700 block would accommodate the two eastbound lanes, which would be shifted 12' to the south. This would allow a smooth through-traffic flow from the 1800 block and without opposing the two westbound lanes.
* The two westbound lanes, after a double right turn onto 18th Street, would be routed one block north to westbound New York Avenue. To accommodate this additional traffic on 18th Street, a double left turn lane and signal timing changes would likely be required.
* To maintain an LOS D or better at two way 17th Street, left-turn movements from E Street should be restricted during peak hours.
* Two driveways on the south side of the 1700 block would have to be reconstructed along the new curb and sidewalk to maintain access to the parking lots adjacent to the Red Cross building.
Impacts of Alternative 1: Transportation
westbound traffic lanes onto 17th Street, which would require restriping 17th to accommodate a wider northbound to westbound turn movement at New York Avenue. All improvements to 17th Street would be within the street's existing curb-to-curb width. However, this option would add more traffic to 17th Street, which is currently operating either at or over capacity during most of the day. These conditions are not be expected to improve under this option.

off-street parking; therefore, the loss of on street parking spaces would represent only a small portion of their parking needs. Patrons and staff could also use commercial parking facilities in the area. Deliveries to the Corcoran could be affected by westbound traffic on E Street between 17th and 18th.
