Area Wide Site Assessments

The City’s Brownfields Program has been awarded several US EPA grants to conduct site inventories to identify brownfields sites in specific neighborhoods. These neighborhoods are considered a priority for redevelopment due to having a higher percentage of vacant, abandoned, and/or nuisance parcels, combined with having fewer economic resources to redevelop these problem sites. These projects include conducting Phase I and Phase II environmental site assessments for some sites.

vacant sites 400Vacant Site Inventory

This project identified vacant or derelict small sites in Los Angeles. Through a USEPA Brownfields Assessment Grant, the LASAN Brownfields Program created an abandoned / underutilized / vacant sites inventory in a user-friendly Web-based database. The inventory was developed using Fire Department files (where storage tank compliance violations were filed); records of underground storage tank (UST) permits; and state and county databases. City staff also conducted site visits to identify underutilized sites. The Inventory is an on-going effort and is updated every year. This internal management and marketing inventory is accessible to City departments and can be shared with developers upon request.


Wilmington and Pacoima mapWilmington & Pacoima Brownfields Assessments Grant


In June of 2011, the City of Los Angeles was awarded a $400,000 grant to conduct site assessments and Phase I and Phase II site assessments in specific neighborhoods of Wilmington and Pacoima. In Pacoima the program has identified sites that can be redeveloped to provide new jobs or be incorporated in a greenway project that is underway along the Pacoima Wash a tributary to the Los Angeles River. In Wilmington, the project aims to reduce the impacts of pollution on the neighborhood by identifying properties that can be redeveloped with businesses that will provide new jobs and an improve community environmental conditions. In both neighborhoods, 27 Phase I ESAs were performed under this grant. A GIS database is being developed to illustrate the findings.

The following sites were prioritized and are currently undergoing assessments, with input from the local Council Offices and other City Departments, in order to conduct Phase I and Phase II ESAs.


Howard Site


In 2013, a Phase I ESA was conducted for the property located at 11424-11432 South Main Street, an auto repair, tire shop and recycling center. There was also a geophysical survey conducted to locate underground storage tanks. The assessment has revealed evidence of RECs in connection with the site (historical use as a gas station/auto repair; hydraulic hoists; oil-stained soil; former wash rack/ drain).

Further assessment (soil sampling and trenching) is recommended by the investigation, the disposition/ status of the UST(s) is not known at this time. In addition, hazardous materials containers/ drums should be properly stored and placed in a secondary containment to prevent any further releases. It is also recommended that an asbestos survey of the structures be performed prior to any demolition activities.

Los Angeles Citywide Assessments

LA Arbor 400The USEPA has awarded the Citywide Brownfields Program a $400.000 grant to address contaminated sites within the boundaries of the City of Los Angeles. These funds will be used to conduct environmental investigation and cleanup planning at eligible sites.

Several Phase I ESAs have been conducted for the sites that present sustainable reuse opportunities as a part of due diligent efforts. The investigations have identified presence of hazardous materials due to historical industrial use. The potential environmental impacts will be evaluated with respect to the future sites’ use.

A Brownfields inventory is being conducted in support of Ecosystem Restoration for one portion of the Los Angeles River Revitalization Plan. The purpose of the Inventory is to identify areas of potential significant environmental contamination that may require further investigation.
