The Bourne in Marseilles, Illinois occupies gently rolling terrain that rises and falls across former farmland now converted to turf. Fairways are planted with bentgrass that transitions into native fescue along the edges, creating distinct playing corridors without artificial borders. Several holes follow the natural drainage swales that run northwest toward the Illinois River, while others climb modest knolls that provide elevated landing areas. A small creek crosses three holes, forcing carries that vary with seasonal water levels. The course uses minimal earthmoving, preserving the existing topography and drainage patterns. Tree lines of mature oaks and hickories define the outer boundaries and occasionally encroach near play, requiring accurate shot placement on several holes. Greens are built to USGA specifications with subtle contours that reward approach shots played to proper angles rather than maximum distance. Cart paths follow existing farm lanes where possible, reducing the need for additional grading across the property.
