VENTURA, Calif. — The Ventura County District Attorney’s Office has launched a major civil environmental enforcement lawsuit against several commercial ranching entities, family trusts, and property owners accused of executing severe, unauthorized land alterations that destroyed local stream systems and wildlife habitats east of Santa Paula.
Ventura County District Attorney Erik Nasarenko announced the legal action against primary defendants Guadalupe A. Guzman, the Lupe and Carmen Guzman Revocable Family Trust, and Santa Paula Hay and Grain and Ranches, LLC, alongside related co-defendants.
The comprehensive civil complaint was formally filed in Ventura County Superior Court regarding extensive, unauthorized land manipulation operations across six distinct ranch properties in the scenic Wheeler Canyon corridor.
Unauthorized Dams, Streambed Grading, and Habitat Destruction
According to official court filings released by the District Attorney’s Office, the civil action stems from years of unpermitted construction, heavy equipment grading, and physical land manipulation across properties associated with the historic Hampton Ranch and Valestrino properties along Wheeler Canyon Road.
Prosecutors allege that the defendants engaged in widespread commercial land development without obtaining required environmental permits or conducting mandatory impact reviews. The alleged illegal activities on the properties include:
- Construction of Ponds and Dams: Building unpermitted retention dams and artificial ponds that blocked natural water courses.
- Stream Channel Grading: Heavy equipment grading that altered and realigned natural streambeds, channels, and banks.
- Placement of Foreign Fill Material: Dumping soil, rocks, and debris into active and seasonal waterways.
- Vegetation and Habitat Removal: Stripping native riparian vegetation, destabilizing soil structures along stream corridors.
- Diversion of Natural Stream Flow: Blocking or altering the natural flow of ephemeral streams that carry seasonal rainwater through the watershed.
District Attorney Condemns Long-Term Environmental Harm
District Attorney Erik Nasarenko highlighted the long-term ecological consequences of unpermitted commercial grading, noting that environmental damage to regional watersheds can take decades to recover:
"The allegations in this case describe significant and permanent damage to Ventura County’s natural landscape," District Attorney Nasarenko stated in an official release. "According to the complaint, waterways, streambeds, and surrounding habitats were altered in ways that may leave environmental scars for generations. Our office is committed to enforcing California’s environmental protection laws, holding offenders accountable, and forcing bad actors to pay for their alleged natural resources destruction."
The prosecution is being handled by Senior Deputy District Attorney Edward Andrews of the District Attorney’s Office Environmental Protection Unit. SDDA Andrews emphasized that strict regulation of streambeds is essential for regional water security and ecological health:
"Years of alleged unauthorized streambed alteration, grading, fill placement, and vegetation removal affecting stream systems in Wheeler Canyon are at the center of this complaint," SDDA Andrews stated. "California’s environmental protection laws are intended to preserve waterways, wildlife habitat, and the long-term health of our communities by ensuring landowners and businesses conduct activities responsibly and with appropriate environmental oversight."
Multi-Agency Investigation and Statutory Allegations
The multi-year environmental investigation was conducted jointly by the Ventura County District Attorney’s Office Special Prosecutions Division, the California Department of Fish and Wildlife, the Los Angeles Regional Water Quality Control Board, the California State Water Resources Control Board, and the County of Ventura.
The civil lawsuit alleges multiple severe statutory violations under California state law:
- California Fish and Game Code § 1602: Unlawful diversion, obstruction, or physical alteration of natural river and stream beds without formal notification and authorization.
- California Fish and Game Code § 5650: Discharge or placement of materials, sediment, and deleterious substances harmful to fish, plants, mammals, and bird life into state waterways.
- California Business and Professions Code § 17200: Violations of California’s Unfair Competition Law resulting from unlawful commercial land practices.
Environmental scientists emphasize that ephemeral streams—waterways that flow primarily after seasonal rain events—are vital components of the local ecosystem. Unlawful grading and filling increase soil erosion, cause heavy downstream sedimentation, degrade drinking water quality, heighten regional flood risks, and destroy critical migration corridors for native wildlife species.
Requested Remedies and Future Court Proceedings
Through the civil action, the Ventura County District Attorney's Office is asking the court to grant comprehensive legal remedies:
- Permanent Injunctions: Enforceable court orders halting all unpermitted grading, filling, and construction activities across the subject properties.
- Mandatory Environmental Restoration: Ordering the defendants to pay for complete, expert-supervised restoration of the damaged streambeds and habitats.
- Civil Penalties: Imposing substantial financial penalties for each statutory violation under the Fish and Game Code and Unfair Competition Law.
- Cost Recovery: Full reimbursement of investigative, legal, and environmental monitoring costs incurred by public agencies.
The civil case remains pending in Ventura County Superior Court as defense counsel and prosecutors schedule preliminary hearing dates.
