Our Origin

Anyone with a connection to the green industry has an interesting and unique story to tell about their introduction and continued passion for their choice of career.  Just ask.

Steve Hohl, principal of Water Concern, began his career in irrigation starting with a summer job processing “diazo” blueprints for a landscape architecture firm in 1988.

It was meant to be a summer job before starting college at UC Irvine as a mechanical engineer.

While working and growing at the firm, Steve established a profound respect for the creative process of blending architectural influence, spacial experience, design development, and enhancement of community through its outdoor amenities.  It brought purpose beyond a design on a blueprint.  The summer job extended through the years learning design principles, construction, planting, commitment to quality work, customer service, and most importantly – client relationships.

With an interest in engineering and a passion for the green industry, Steve transitioned to Landscape Irrigation Science where the merging of soils, horticulture, landscape architecture, and engineering created a niche that served both talent and passion.

“Doing what you love creates intrinsic value, enhances reward, and motivates effort.”

After earning one of the first accredited degrees in Irrigation Science, Steve led an irrigation department for several years before creating Water Concern.

“My favorite part of my career is the people and the relationships sustained through the years.”

Irrigation is more than sprinklers, drip irrigation and water pressure.  It is a balance of water and resource management, efficient application, proper equipment, and understanding how the landscape is used and how it is maintained over time.

Steve was honored with the status of Fellow with the American Society of Irrigation Consultants.
