Inquiry

A private company is developing a one level underground parking garage and will operate this facility independently from any future development that may occur above it. This project will be privately financed, operated, and constructed. The one level parking garage will fill the property boundary area and will be designed to accommodate future structural loading from separate projects that may occur above. A nominal 4 ft vertical separation between the concrete parking garage roof podium and future construction is planned to allow for the inclusion of utilities and vegetated areas. Program elements that may need to penetrate the garage will be isolated from the remainder of the garage. Presently, the garage is intended for users of adjacent sites rather than for users above the facility. It is undetermined if the underground garage project will seek LEED certification. The project is scheduled to start construction in January 2008 and finish in January 2009. The City is planning to build a separate publicly financed and operated project consisting of a 750-seat performance hall on top of a portion of the independent privately financed underground parking garage project. The Performance Hall project, per City Ordinance, is presently pursuing LEED Silver certification and is scheduled to start construction in December 2008 and finish in 2010. This Credit Interpretation Request seeks a determination of the LEED Project Boundary for the 750-seat Performance Hall project. It is assumed that the LEED Project Boundary will vertically be the construction above the underground concrete parking structure podium and horizontally the extent of the construction above. Thus the Building Footprint, Development Footprint, and Open Space Area components will be the portion that is directly above the podium but does not include the independent underground parking garage project. Please provide a ruling clarification regarding the vertical LEED Project Boundary including the Development and Building Footprints for the referenced Performance Hall project.
