Federal Commission Approves D.C. Design and Security Plan | |||||||||||||

The National Capital Planning Commission (NCPC) on July 11 approved a security plan that advocates say secures and beautifies building perimeters in the nation's capital. The proposal responds to the disparate and unattractive fortifications that now serve as makeshift security measures in and around Washington. The NCPC voted to open the plan, developed by its Interagency Security Task Force, for a 60-day comment period. The measures, detailed in a 97-page draft report, The National Urban Design an Security Plan, include integrated, custom-designed, hardened furniture that would include tree wells, bollard fences, plinth walls, light fixtures, benches, drinking fountains, seat planters, and bus shelters. A "circulator" bus system that would move workers and tourists among designated points in downtown is also in the proposal. The task force relied on the work of prominent designers and security experts. Each of the design firms was responsible for a discrete area of the city; they then came together to integrate their ideas into a cohesive plan. NCPC project manager Elizabeth Miller said the recommendations concentrate on the perimeter of security that surrounds federal property and not on making modifications or improvements to the buildings themselves. The task force envisions that the actions taken in D.C. could serve as a model for other areas across the nation grappling with similar design issues. The plan recommends design solutions for threats of unauthorized vehicles approaching or entering sensitive buildings; not bombs carried by pedestrians, air attack, or chemical or biological weapon terrorism. "It's not a cure-all for all city security issues," said Richard Friedman, a Boston developer and task force chair. "We're dealing with garden-variety issues of terrorism and we're dealing with decades of neglect in urban planning in the city," Friedman said, noting the "creep of security agencies and people doing urban planning in the District." Design
concepts The design scheme divides the city into: For example, Pennsylvania Avenue, a special and perhaps the most symbolic thoroughfare in the city, would have its own design framework, which now includes a pedestrian park in front of the White House. The plan for the Lincoln and Jefferson Memorials calls for bollards and planters as well as low walls of stone to match the monuments, which would encircle landscaped slopes and the monuments themselves. A family of streetscape elements has been designed for each contextual area or special street. There are seven basic security design concepts. They include hardened street furniture, fences or fence walls, plinth walls, hedges and bollards, planters, bollards, and custom-designed solutions. The recommendations are based on the strength and effectiveness of elements already in place in D.C. The new designs will need to be engineered and crash-tested to verify their effectiveness. The task force notes that not all buildings require the same levels of security; each agency must determine a building's required level of protection and standoff distance per General Services Administration guidelines. The agency can then select the most appropriate combination of perimeter barriers. Implementation The security recommendations carry an $800 million price tag, but Friedman noted that this amount does not exceed current and proposed spending by each federal agency on security modifications since September 11. The figure also assumes a "worst-case scenario" implementation of the plan, where nearly all of the buildings would be protected against the highest level of threat. A more realistic cost estimate could be discerned after officials continue risk-assessment, design and testing of proposed security elements, and parking and traffic studies. The NCPC recommended $30 million be allocated in FY 2003 to complete design studies. The task force recommended that Congress and the Office of Management and Budget designate a lead agency to administer and coordinate the design, permitting, and construction of street and area projects, including the engineering and testing of security components. The group mentioned the Federal Highway Administration as one possibility. After considering and possibly revising the plan based on public comment, the commission will present the plan to Congress.
