Lendrum Court Remediation

​Project Description
Lendrum Court is located in the northwest corner of the Presidio, north of Doyle Drive, in the North Fort Scott Area, entirely within Area B. This residential area of the Presidio includes Lendrum Court, Armistead Road, Hoffman Street, and Ramsel Court.

The Trust performed selective soil testing to investigate the presence of Army-era debris found beneath the ground surface in the Lendrum Court Area. The subsurface debris includes abundant glass, ceramics, and terra cotta, as well as lesser quantities of cobbles, brick, charcoal, wire, metal, small animal bones, and burned wood and ash. Lead and other chemicals were detected at concentrations that could potentially pose a human health or ecologic risk if individuals are exposed to contaminated soils through ingestion, inhalation or dermal contact. Of particular concern is the presence of glass at the ground surface. The glass and contaminated soils have been brought to the ground surface via gopher activity, increasing the potential for human exposure.
The Trust reported the sample results for the debris fill to the California Department of Toxic Substances Control (DTSC). The results are described in a report titled Lendrum Court Investigation Summary Report and Risk Screening Evaluation. Under the direction and oversight of the DTSC, the Trust is conducting additional investigation to define the extent of debris soils and to develop action plans to prevent human and ecologic contact with the debris.
In Progress through Spring 2014
The Trust is implementing temporary actions to minimize potential human exposure to the debris found in Lendrum Court while permanent remedial actions are developed.
Spring 2014 through Fall 2014
Under the direction of DTSC, the Trust will conduct additional sampling and testing in the neighboring North Fort Scott neighborhoods and within Lendrum Court to delineate the full extent of the debris, confirm what chemicals are of concern, and determine if any risk is posed to individuals living in and visiting the neighborhood.
Fall 2014 through Winter 2014
Once the extent of the debris and its nature is defined, the Trust and DTSC will develop final actions to mitigate the problem. The Trust is expediting the remedial actions.
Summer 2015 through Fall 2015
Final restoration of the neighborhood is completed.
