White House security: It takes more than a fence

White House temporary security
Temporary barriers on Pennsylvania Avenue in front of the White House were installed recently to prevent more intrusions into the grounds.

Over the past year, there have been repeated security breaches at the White House involving intruders jumping over the perimeter fence. Three years ago, a man opened fire from a car on Constitution Avenue, breaking the outer pane of a window in the private quarters of the president and his family. Clearly, corrective measures are needed to guarantee the safety of the First Family—and temporary barriers are once again in place along the Executive Mansion’s Pennsylvania Avenue frontage, joining the barrage of unsightly barriers on the south side of the White House.

Over time, the White House property has evolved from a villa within open grounds to an increasingly fortified complex. Originally on a single lot between East and West Executive Avenues, the White House now is at the center of a larger controlled security zone that stretches from 15th to 17th Street and from H Street to Constitution Avenue, requiring the closing of Jackson and Madison Places, East and West Executive Avenues, Pennsylvania Avenue, and E Street within the last 30 years. While the needs of security are understandable, the impact on the surrounding city has been drastic—particularly for Pennsylvania Avenue, now only a vestige of its former role as the city’s main street.

The recent incidents of intrusion into the White House complex have involved both a fence—which, at seven feet six inches, is possible to scale—and compromised operations in detection and apprehending intruders.  Certainly, it is very difficult to prevent a determined trespasser from jumping a fence, but the kind of “no-climb” fences that can actually prevent it are hard to imagine ringing the White House grounds. There are ways to make a higher fence appropriate for its context, although it’s a fine line between appropriate and overwhelming.

Since the 1995 Oklahoma City bombing, and even more since 9/11, heightened security requirements in Washington have altered the relationship between the public and many of our government buildings—museums, monuments, and government offices—with bollards, security screening posts, and closed streets. Most of the federal projects reviewed by the Commission of Fine Arts today include perimeter security barriers, from double fences around secure office campuses to stone retaining walls integrated into the landscape of national memorials.

Security requirements vary for federal facilities, but the most successful ones do their job of protection while contributing to the public setting. This example at the Smithsonian’s National Museum of American History uses the simple modern language of the architecture to create a harmonious vehicular barrier along Constitution Avenue.

When Pennsylvania Avenue north of the White House was closed in 1995, the city’s street network suffered, but the space itself was redesigned to make pedestrians feel welcome. There is a balance to be found between openness and security, and during design review, the Commission and its staff work with agencies to make security installations as open and transparent as possible while minimizing the effect of the installations on the public environment.

The security of the White House and the protection of the president cannot be solved by a higher fence alone. We encourage the Secret Service and the National Park Service to think holistically in addressing the issues of threat on many levels: physical, operational, and as a wider protected zone. Any solution must be an effective combination of physical barriers and operational procedures to prevent further intrusions. However, the real opportunity lies in a comprehensive approach to the White House security zone: to clean up the accumulation of “temporary” barriers, booths, and screening facilities located on lawns, sidewalks, and roadways—including the Treasury Department, the Eisenhower Executive Office Building, and the National Park Service properties of the Ellipse (President’s Park South) and Lafayette Square.

E Street security barriers

The current landscape along E Street looking northward to the White House is a hodge-podge of temporary and permanent security elements.  Nearby structures for visitor screening, guards, and even mechanical equipment create an undignified environment for the national seat of executive power.

Meanwhile, plans to redesign the E Street frontage—currently a repellent array of jersey barriers, bollards, and fences—are on hold, as is the General Services Administration’s 2011 proposal to consolidate many temporary entrance screening facilities around the EEOB into an elegant pavilion under the building’s north plaza facing Pennsylvania Avenue. We agree with the recent Washington Post editorial, “No change should or need impinge any further on the White House’s historic openness. Security concerns need not block the American public from its heritage.” The best solution is the one that intrudes the least, and offers in return for its fortifying function the reminder that the public is welcome—and safe—at the national seats of power.

You do not want an ugly, prison-like barrier; what you do want is a real time warning that someone is attempting to breach the fence. We have an existing U.S. Patent 7,760,046 B2 that uses low frequency RF waves to monitor a long fence in real time. The DoD gave the technology a positive review back in 2006 and we proposed it to monitor border fences and pipelines along with RR tracks, but no Federal agency would even consider it for its intended roles. It is still a viable technology today.

No private cars should be allowed within one block of the White House. In terms of the fences. Put a fine mesh fence in the semi-circle of hedges in front of the White House. It will be invisible to the public on the sidewalk but being flexible it will be next to impossible to climb over. As for a Moat, it would not be a bad idea, just fill it with water and call it a decorative pool. Your main goal is to slow anyone trying to enter the White House down and to funnel those who try to avoid the fences/barriers into areas where there are more Secret Service/White House Guards.

One idea for the White House security fence is to have a curved lip at the top of the iron fence facing the outer perimeter of the property. A person trying to climb the fence will have to climb upside down to get over. I have seen such fence on Oahu, Hawaii .

I suggest a slick metal or glass, freely rotating 8-12 inch axle along the top of the fence which, when grabbed, would not only freely rotate towards the person causing him to lose his grip, but would engage a motor which would spin and make it impossible for the person to hang on and hoist himself over. This engagement would also trigger an alarm.

I agree with Dantes' idea of a revolving top section of some sort being the obvious way to go, plus add at least one 'haha' between the fenceline and the building complex. It would serve a similar purpose to a moat but be a far smaller project, far less expensive and very inconspicuous when viewed from the buildings or on the road - that was the point of having hahas after all - to control access without spoiling the view. If that wasn't enough, it could easily have one or more electric wires strung along the top edge of the haha's wall (on the White House side) so anyone who tried to climb up out of the haha's ditch would get a nasty jolt.

The proposed fence (11 feet, 7 inches on top of a base that varies from 18 to 30 inches) is higher than it needs to be. The current olympic high jump record, set in 1993, is 8 feet 1/2 inch. The current olympic pole vault record, set in 2012, is 19 feet, 7 inches. The proposed new fence will not come close to stopping pole vaulters. However, a fence of perhaps 9 or 10 feet, including the base, ought to be adequate for jumpers, olympic or not.

please reconsider adding another layer of iron fence, to the point it will take away from the asthetics of this fine peoples house. what "aunt betty" gonna see in her visit is an ugly fence, and not the great residence. as a former physical security-force protection guy in the us army, let us consider old fashioned european..."sticker bushes"...the germans do ok keeping out uninvited guest. say about 4 feet high by about 5 feet wide, keeping persons from touching the current fence, and leaving the view unobstructed. sources that can provide input, include horticulture shops in art galleries. thank you harold williams us army retired
