Duininck Golf Makes Greens out of Garbage, Expands River Ridge Golf Course

Whether it’s converting a landfill into a beautiful golf course or working through

mountains of red tape, the tough job are no match for Duininck Golf. 

PRINSBURG, MINN – Duininck Golf, a division of Duininck Co. announced that it recently completed construction of a nine-hole addition to River Ridge, a municipal golf course owned by the City of Oxnard, California. The project, known as River Ridge, Phase II, was highlighted by its many challenges, the biggest of which was building seven of the new holes over an existing landfill, with minimal impact to the environment.

The $7.8 million dollar project added nine new holes to enhance the previously 27-hole course, located on the ocean shoreline near Malibu and just northwest of Los Angeles. Seven of the nine new holes were built over a pre-existing landfill. Duininck Golf was entrusted to cover the landfill and turn an eyesore into a beautiful and useful area; all the while adhering to the stringent environmental standards California is famous for. The additional holes were complete on time and budget despite numerous challenges.

Some of the building challenges included:

Covering the landfill – Covered waste areas with a specified, pre-approved fill, with thicknesses ranging from two to 15 feet in places. Compacted and tested using two different methods to meet project densities.

Use of polyethylene fused piping – The landfill closure required the use of fused pipes – pipes which resist being pulled apart – for the drainage and irrigation system.

Working around existing methane extraction system – Work around and protect fragile existing methane pipes, which are used for methane gas extraction.

GPS accuracy – River Ridge was laid out and constructed with GPS precision to meet elevation levels needed for approval by the State regulatory agency.

Feature Lining – PVC liners were added in highly concentrated irrigation areas to prevent seepage into the landfill.

Dust and Erosion Control – Working within the confines of existing residential development and golf course, erosion and dust control was monitored at all times.

Building sloped ground – Also in line with California standards, the non-lined areas of the course needed excessive slope (3%) to aid in water runoff and collection.

Working through red tape – Patience is often required to deal with the paperwork involved in projects like River Ridge. Duininck Golf’s unfailing goal is to build quickly, correctly, and responsibly.

“Duininck Golf did a great job from start to finish,” said Ralph Alamillo, Construction Project Manager for the city of Oxnard. “They paid attention to everything from the big picture, to the smallest details. We’d work with them again in a second.”

The work for River Ridge is just one example how tough jobs are no problem for Duininck Golf. Duininck Golf strives to be the best, from the first tee to the clubhouse.
