Volunteers Help Remove 200 Tons of Dirt, Flood Debris from Oceano Ranch

2023-02-12T08:11:41-08:00

Volunteers from The Holloway Group and Team Rubicon spent much of Saturday helping remove more than 200 tons of debris and dirt from the flood-plagued Cardoza Ranch in Oceano. All 12 acres of Pat and Vickie Cardoza’s ranch was flooded – by as much as 10-15 feet of water in some areas – in mid-January when storm runoff in Arroyo Grande Creek ran over a failing levee and flooded their home and farmland south of Oceano.

Everyone called him “Dad,” from his friends to his family. He was known in the valley as the crazy fellow out in Lost Hills with ideas about mining gypsum for agriculture. To young Al Holloway, he was just the greatest man to ever walk the earth. His name was Harvey Mulford Holloway (H.M. Holloway), and he was the boy’s grandfather.

This Clark Equipment ad from Engineering and Mining Journal in November 1964 highlights Holloway’s Lost Hills Mine with a photo of a Michigan Tractor Scraper that scraped 1 million tons of gypsum between 1959 and 1964. Since 1932, Holloway has been the leading supplier of soil amendments to the south Valley, scraping, delivering and spreading more gypsum than any other supplier. Today, as part of an occasional series entitled "90 Years & Still Growing ..." highlighting Holloway and California ag history, we look back at our founder and celebrate the early days of H.M. Holloway and how our 90-year-old company came to be.
