US COAST GUARD – EMERGENCY RESPONSE CLEANUP ACTION AND POWER RESTORATION AT POINT BONITA LIGHTHOUSE

  • Client: US Coast Guard
  • Location: Point Bonita Lighthouse, Sausalito, CA
  • Date: October and November 2021
  • Contract #: 70Z08821FPQQ19200
  • Value: $207,515.00

Project Details

Point Bonita Lighthouse reopened to the public in July 2021.  Upon reopening, it was discovered that a transformer on one of the power poles supplying power to the lighthouse had failed and was leaking oil onto the ground.  PG&E commenced initial actions by severing power to the light.

Cerrudo Services provided all labor, materials and equipment to conduct emergency environmental testing and cleanup, replace the transformer and power pole, and restore power to the lighthouse.  Cerrudo tested the leaking transformer oil for PCB’s; none were detected.  The existing transformer was removed from the pole and the oil recovered in sealed vessels.  The pole was cut down in sections, then the base of the pole was jacked out of the ground, five feet deep.  The pole sections and transformer were removed from the site.

Cerrudo utilized a helicopter to transport the new pole and transformer to the site.  A detailed flight plan was submitted to and approved by the Coast Guard.  The new pole was set and the transformer attached to the pole.

Cerrudo retained an archaeologist to monitor all excavation work for any artifacts of interest.  None were found.

COMPREHENSIVE TACTICAL INFRASTRUCTURE MAINTENANCE AND REPAIR, AREA 1, CALIFORNIA – ENVIRONMENTAL ISSUES

  • Client: Department of Homeland Security
  • Location: 130 Miles along the California / Mexico Border
  • Date: 2015
  • Contract #: HSBP1012-C-00007
  • Value: $24,188,870

Project Details

As part of Cerrudo’s work on this project, several ecological and environmental concerns arose that required mitigation.  Along the Tijuana River Basin we performed vegetation clearing in critical habitat areas for the Least Bell’s Vireo, (State endangered species).  Cerrudo employed a certified biologist to perform a pre-activity survey and marking of the Vireo’s critical habitat to be protected, and provide full time oversight of operations to ensure compliance.

At the Otay Mesa Port of Entry Channel, Burrowing Owls were discovered.  We employed a Biologist to conduct a pre-activity survey of the project area and prepare nest survey report.

Bureau of Land Management land in the El Centro project area is subject to the Flat Tailed Horned Lizard (FTHL) Range-Wide Management Strategy.  Cerrudo employed a FTHL Monitor to conduct a pre-activity survey of all roads within the project scope and to provide oversight of road work operations to ensure compliance with the FTHL Protection Plan.

HAMILTON ARMY AIRFIELD COASTAL SALT MARSH EXCAVATION

  • Client: US Army Corps of Engineers
  • Location: Novato, CA
  • Date: 2006
  • Contract #: W912P7-05-C-0003
  • Value: $5,223,998

Project Details

The Coastal Salt Marsh at the former Hamilton Army Airfield required remediation to address elevated levels of contaminants by removing contaminated soil from the marsh.  Soil was excavated in the outboard marsh from several specific sites ranging in size from a few hundred square feet to several acres and as much as three hundred feet outboard of the bay front levee. Cerrudo Services excavated, stockpiled and disposed 33,208 cubic yards of contaminated soil from a total of 10 separate sites located within the coastal salt marsh tidal zone.

Minimization measures were implemented to protect the salt marsh harvest mouse, the California clapper rail and other fauna and flora from the effects of remedial actions.

Bay water tidal influences into the excavation areas were a major concern.  Control measures such as sediment traps and a barrier placed at the downstream end of the drainage ditch were devised to eliminate migration of contaminants into the bay by receding tide water.

HAMILTON WETLANDS RESTORATION – BUILDING DEMOLITION, ASBESTOS AND LEAD ABATEMENT

  • Client: California State Coastal Conservancy/US Army Corps of Engineers
  • Location: Novato, CA
  • Date: 2004
  • Contract #: W912P7-04-C-0002
  • Value: $394,820

Project Details

Cerrudo Services prepared the Hamilton Air Field for wetlands restoration by demolishing and disposing of many buildings and incidental facilities over an area covering approximately 1,000 acres.  Work included hazardous material surveys, lead and asbestos abatement and demolition of numerous structures.  Work plans were implemented that stressed environmental protection for the ecologically sensitive site.

Prior to demolition all utilities were terminated safely.  Lead and asbestos was abated from the structures prior to demolition.  Water misting was used as a dust suppressant during demolition.  Structures ranged in age and complexity including CMU, steel frame and wooden construction.
