Updates on the odor issue affecting Portola Hills will be posted on a new City webpage, along with relevant documents and studies.
The odor was reported in mid-April. The City ordered Baldwin and Sons to stop work when their grading work was identified as the source of the odor.
Baldwin and Sons sprayed the site with water and a non-toxic chemical to tamp down the odor. Organic materials mixing with oxygen were identified as the source of the odor. Studies found no apparent risk to the public's health.
When the water didn't stop the odor, Baldwin capped the site with 2 to 3 feet of soil. The developer retained a consultant to create a remediation plan. That work was reviewed by a consultant hired by the City.
Work began on May 24. By June 9, 10,000 cubic yards of soil had been removed. Another 10,000 cubic yards was expected to be removed by the week of June 21.
The community's health and wellbeing are the City's top priority.
