Safeco Field, Seattle Mariners

D.A. Hogan & Associates was the field design consultant for the Safeco Field project, home of Seattle Mariners Major League Baseball. The stadium’s retractable roof and seating areas create a challenging environment for healthy turf grass. The sun/shade patterns for the field were closely studied so that the field systems could be configured to address the various micro-climates across the field area. These systems include subsurface air and drainage, hydronic heating, and automatic irrigation. The irrigation system is integrated with the stadium ground water collection system for recycling purposes.
