Reston Herndon Fairfax Connector Bus Operations Facility

September 6, 2018
The project to renovate the Fairfax Connector Reston-Herndon Bus Operating Facility, located at 268 Spring Street, Herndon, Va., was substantially completed on July 27, 2018. The $12,633,300 project was undertaken to improve the efficiency of the facility where 80 Fairfax Connector buses are maintained and repaired. To allow operations to continue uninterrupted, the building was renovated in phases. Staff now have a working environment that is safer, more efficient, and more comfortable than before. This project was managed by the Department of Public Works and Environmental Services. The renovated facility was designed by Michael Baker International, Inc. S3E Klingemann, Inc. was the mechanical, electrical, and plumbing engineer. Woods Peacock was the structural engineering firm, and BC Consultants was the civil engineering firm. The general contractor was Branch & Associates, Inc. Renovation Highlights: An existing open bay was enclosed to create a new drive-through bus wash. A small addition was constructed for exterior tire storage. Vehicle lifts and service equipment were upgraded. An automated parts storage system was created. The drivers lounge and administration areas were modernized. A new covered fueling station was added. The bus parking lot surface was replaced with new heavy-duty concrete. A new parking lot was added for staff. A new restroom was constructed. The renovation project was funded by the Northern Virginia Transit Committee State Aid and the voter-approved 2007 bond referendum. The Reston-Herndon facility renovations follow improvement projects completed at the Huntington and West Ox Bus Operations facilities.

Public Safety Headquarters front plaza

July 16, 2018
On June 28, 2018, the Fairfax County Public Safety Headquarters located at 12099 Government Center Parkway, Fairfax, Va., achieved LEED Gold certification from the U.S. Green Building Council. Certified buildings are resource efficient and less expensive to heat, cool, and maintain. LEED (Leadership in Energy and Environmental Design) projects are scored based on points earned in six sustainable design categories: site selection, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, innovation in design, and regional priority credits. With the addition of PSHQ, Fairfax County now has 15 LEED Gold certified and 15 LEED Silver municipal buildings. The nine-story, 274,000 square-foot PSHQ accommodates both Police and Fire and Rescue Department administrative staff to maximize shared resources among first responder agencies that often work together in the field. The project is located on a secure 9.3-acre portion of the Fairfax County Government Center campus, adjacent to the Herrity Building, and includes an 850-stall parking structure. The facility is designed to accommodate more than 700 employees by 2030 and includes space for Police central records, a press room, training rooms, an occupational health center, fire marshal’s offices, exhibit areas, and departmental memorials. The total project budget for the new facility was $142 million. The building is the county’s first large facility to use LED lighting throughout. Sustainable Design Highlights: Green roofs, permeable pavements, and stormwater management features work together to slow down, filter, absorb, and purify rain water as it leaves the site. A 25,000-gallon tank harvests some of the runoff and reuses it for on-site irrigation. Daylight harvesting sensors take advantage of natural lighting and adjust indoor light levels depending on the amount of sunlight available. Low-flow plumbing fixtures Eco-smart environmental controls Permeable pavement Daylight harvesting Bio-filtration areas Recycled materials Use of low VOC emitting materials improves the interior air quality The PSHQ project included improvements to the surrounding area including a new traffic signal, sidewalks, bus shelter, enhanced campus signage, and increased pedestrian safety. A grand opening and ribbon cutting ceremony was held on October 26, 2017. The project team consisted of Department of Public Works and Environmental Services staff; the design consultant team of Hellmuth, Obata, and Kassabaum, P.C. (HOK), architect; William H. Gordon Associates, civil engineer; and the general contractor was Manhattan Construction Company. PSHQ was recently recognized with a Project of the Year Award  (Structures: $75M+ category) by the Mid-Atlantic Chapter of the American Public Works Association in May 2018. The awards program highlights the best infrastructure projects in the national capital region. Click to Download  

oil in water in storm drain

June 26, 2018
In Fairfax County and other areas of the country, polluted stormwater runoff is a leading cause of water pollution. The county drainage system is designed to convey stormwater, rain and snowmelt, from the land to lakes, rivers, streams and ponds. Stormwater is not conveyed to a water treatment plant. Stormwater from streets, yards and parking lots may carry chemicals, bacteria and trash into the storm drainage system, to streams and rivers and to the Chesapeake Bay. Working together, we can prevent water pollution that harms fish, wildlife and natural habitats. Here are a few examples of steps anyone can take to prevent water pollution: Secure trash and recycle containers to prevent these items from becoming litter Follow the manufacturers’ instructions to minimize pesticides, herbicides and fertilizers used on lawns Take vehicles to a commercial car washing establishment which prevents dirty, soapy water from entering a storm drain in your street Avoid raking or blowing grass clippings into storm drains Call 703-324-5500, TTY 711 to report items such as paint, fertilizer or other chemicals that are deposited into storm drains Call 911 in an emergency situation where materials are deposited into a storm drain that could result in imminent danger to public health and safety For more information about preventing water pollution, see the Illicit Discharge and Improper Disposal Program web page.
