The IRS Kansas City Campus is located just south of downtown adjacent to Liberty Memorial and Union Station. This facility can hold up to 8,000 IRS employees and provides multiple outdoor environments for breaks and outdoor gatherings. The design establishes a strong connection between interior and exterior spaces while balancing issues of security, sustainability and urban design.

BNIM was responsible for the design of all site landscaping, courtyards, grading, irrigation, stormwater collection system and green roofs. BNIM worked with Kroll Security Group to design an aesthetically pleasing secured perimeter that also meets IRS, GSA and Homeland security requirements. The perimeter was secured by integrating natural limestone walls, ornamental and vinyl coated fencing, appropriate setbacks, ram barriers at key locations and vegetated buffers.

Additional sustainable site components include:
- Amenities to improve the quality of life for employees of the facility. 
- Interior courtyards, green roofs, walking trail, natural lighting, and views to the outdoors where created all while maintaining the high security requirements of project. 
- A plant palette made up of 80% native species to reduce the water use by 93% from traditional practices. 
- Captured stormwater from the 70,000 square foot warehouse roof that is stored for irrigation and provides a pleasing water feature for IRS employees. 
- Green roofs covering 1.5 acres of the site to greatly reduce the heat island effect typical of such a large building footprint.
