Seismic Hazard Liquefaction and FEMA Flood Hazard Zones Omitted from East Weddell DEIR


Oh . . . oopsy! just a little omission from the East Weddell Projects Draft Environmental Impact Report (DEIR)  proposed for 670 apartments- not only is the ground contaminated with hazardous carcinogens, but the whole area is in a Seismic Hazard Liquefaction and FEMA Flood Hazard Zones conveniently omitted from  disclosure on the report.

You wonder how these big developmental projects get approved? It starts in the City of Sunnyvale Planning Department. In fact, the “lead agency” for the is the City Planning Staff, so they get to decide how to direct the EIR report.

The lead agency must analyze project impacts to 18 different environmental resource factors detailed in Appendix G during their CEQA review, yet some very important items have been omitted by direction of the City of Sunnyvale Staff.

The East Weddell Projects DEIR identifies hazardous contaminants – Arsenic, VOC, tetrachloroethylene (PCE), vanadium, groundwater containing petroleum hydrocarbons in the diesel and motor oil, to name a few, which place residents at high risk for adverse health known to cause cancer. Analog Devices, at 610 East Weddell Drive, was listed as a registered hazardous waste generator and identified as responsible for the release of 100 gallons of liquid hydrogen during an incident in 2006. The failure to disclosure liquefaction and FEMA Flood Hazard Zone proximity is a disservice to the Sunnyvale residents and this report.

Since liquefaction can occur when loose, water saturated, fine-grained soils (such as sands and silt) are shaken during an earthquake, what is the impact of the hazardous ground contaminants and proper mitigation, if any? Soil can temporarily become liquid like and structures may settle unevenly. If present, these weak materials can fail during an earthquake and, unless proper precautions are taken during grading and construction, can cause damage to structures.

Concerned Citizens – comments received until Oct 23rd. Please email your comments to Sunnyvale Planner Trudi Ryan tryan@sunnyvale.ca.gov, Community Director Hanson Hom at hhom@sunnyvale.ca.gov, Ryan Kuchenig rkuchenig@sunnyvale.ca.gov, Heidi Kirk hkirk@sunnyvale.ca.gov

And if you would like a Natural Hazards Report of these natural hazards conditions, please email eyesunnyvale@gmail.com and we will forward to you.

    These are huge omissions by city staff. Many elderly people, children and teenagers walk on the bike path (hetch-hetchy) at E Weddell everyday, right past the proposed site. Demolition of the buildings- on both sides of Weddell- puts thousands of N. Sunnyvale residents at Maximum Cancer Risk.
