Baltimore Grand Prix Pit Row at Oriole Park at Camden Yards
Baltimore, Maryland

Baltimore Grand Prix Pit RowWBCM provided full design services, construction documentation, bidding review, and construction administration services for the alterations required to convert the area along the east side of the Warehouse at Camden Yards into a pit lane for the Baltimore Grand Prix. The project was completed on an accelerated timeline with design being initiated in May 2010 and construction being completed before the Major League Baseball (MLB) Opening Day on March 31, 2011.

WBCM designed alterations to the five-acre site to allow use as a parking facility and public street for fifty-one weeks out of the year while still being easily converted to accommodate the Baltimore Grand Prix pit row and race course for one week a year. In addition to meeting Indy Racing League (IRL) requirements, WBCM designed the modification to comply with the Maryland Department of the Environment’s (MDE) Stormwater Management (SWM) requirements, American with Disabilities Act (ADA) requirements, and the Maryland Stadium Authority’s Sustainable Building Design Initiative.

WBCM provided MSA with an innovative solution to the site’s stormwater management by incorporating a rainwater harvesting system into Camden Yard’s existing storm drain system, a first-of-its-kind retrofit for a MLB stadium. The harvesting system intercepts several of the warehouse’s roof leaders and routs them to a common manifold that conveys storm flows to a 6,000 gallon precast concrete rainwater tank. A wet well/dry well stormwater pump station and a 2,500 LF distribution network allows the captured stormwater to be used for irrigation of site landscaping. WBCM also designed a microbioretention within the existing parking area and modifications to the existing closed storm drain system to accommodate the planned road widening and IRL’s requirements.

Construction was phased to maintain vehicular traffic and to accommodate the crowds from both the Baltimore Orioles and Baltimore Ravens home games.
