The City recently engaged a Master Arborist to analyze the city owned trees on the southern portion of Parcel 13 and recommend a tree-specific maintenance plan. The report and recommended actions are available here: TreeCare LA Report on Parcel 13 Eucalyptus Row - March 2017
On Nov. 21 and 22, 2015 trees were removed from Parcels 12 &13 that raised concerns in the community about public health and the loss of vegetation and green screen. (Parcels 12 & 13 Arborist Report) Soils in Parcels 12 & 13 have long been known to contain above naturally occurring levels of arsenic from prior use as a railroad right-of-way.
The City’s primary concern is the health of this community and the City has taken numerous steps to determine the level of risk from the soils on the parcels and the tree removal, and to mitigate that risk. To accomplish this the City has retained consultants who have tested the air and conducted soils testing both on and off the property.
Test results taken soon after the removal of the trees in 2015 indicate that there was no risk to the community from being in the vicinity of Parcels 12 and 13. In addition, there was no evidence that suggests that contaminated dust migrated outside of the parcels immediately following the removal of trees. Results of the 2015 testing are in the documents listed below.
The City did testing of soil samples during July and August 2016 in the public right of way, in order to determine mitigation necessary for the Santa Monica Boulevard Reconstruction Project. Results of Arsenic Sampling on Parcels 12 & 13 July-August 2016
The City will continue to work closely with the State’s Department of Toxic Substances Control (DTSC) to protect the public health and ensure that no contaminated soil escapes from the properties. The DTSC is the agency charged with oversight of investigation and remediation on the parcels. The parcels have been sprayed with an approved compound designed to suppress dust and bind the surface soils.
