At the Los Angeles County Fairgrounds (Fairplex) in Pomona, a section of the grounds was upgraded to provide a more park-like visitor experience. This included the Farm at Fairplex demonstration garden, where Organic-Lock Stabilized Aggregate was used for walkways between planting beds and event areas. The OLSA paths handle heavy foot traffic of fairgoers while reducing dust and glare compared to pavement, and they drain quickly after irrigation or rain.
