Erosion and Ash Control Product Applied to Residences and Other Burned Areas in the City of Ventura

The City of Ventura Public Works Department hired Galion Erosion Control to spray EarthGuard onto residences and other areas burned by the Thomas Fire.  The application is a public service to help keep hazardous material from getting into the stormdrains by keeping it in place and preventing it from going onto other properties, as well as preventing the material from becoming airborne. EarthGuard is a polymer product mixed with water and sprayed with the same equipment used for hydroseeding.  The product will not impact sifting of personal materials and will not affect the ability to see properties.

EarthGuard is a non-hazardous, non-toxic product and will not cause any issues with the watershed or the replanting or re-growing of plants. It is used on construction projects throughout the nation for dust control.  The product is mixed with fiber and is green in color in order to show where it has been applied.

The application of EarthGuard began on December 12, 2017 in the homes where hazardous material burned.  The spraying began in the Clearpoint neighborhood and will proceed to Ondulando east, Ondulando west, Skyline, Hidden Valley and continue west. Other areas to be applied with EarthGuard include water facilities and parks citywide that were impacted by the Thomas Fire.  The spraying of EarthGuard is slated for the next few weeks. 

Other best management practices to control erosion include the use of straw waddles, silt fencing, and plastic sheeting; however, at this time these materials present a fire danger.
