Since 2007, E2 personnel have provided on-call environmental engineering services to the Community Redevelopment Agency of the City of Los Angeles (CRA/LA). On-call services to date have included Phase I ESA, Phase II Site Investigation, Health Risk Assessment Services, Remediation Feasibility Studies, and Brownfield Area-Wide Inventories. Under this contract E2 has completed multiple Phase I ESAs on properties that CRA/LA is considering to provide funding in support of redevelopment projects on the subject properties. Each of the Phase I ESA that have been completed were prepared in accordance with latest ASTM Standard Practices for Environmental Site Assessments: Phase I ESA Process (ASTM Designation: E1527-2005) and in compliance with the Federal All Appropriate Inquiry (AAI) rule (40 CFR Part 312 – Standards and Practices for AAI).

E2 is currently conducting a Remediation Feasibility Study for a former industrial use property that CRA/LA is considering redeveloping under its Brownfield program. To complete this Feasibility Study, CRA/LA requested that E2 develop an additional remediation screening criteria that would evaluate green remediation in addition to the standard 9 criteria that are used by EPA to screen remediation/clean-up alternatives. To accomplish that goal, E2 has identified green remediation evaluation criteria that consider reduction green house gas emissions of the various alternatives, use of recycled materials, reduced energy and fuel consumption, and reduced water usage. Clean-up alternatives that are being evaluated include soil washing, phytoremediation, excavation, and capping.

E2 is also conducting an area-wide inventory of industrial properties that could qualify as a Brownfield property as defined by US EPA. The inventory area includes an eight block area and over 200 industrial-use parcels. To complete this inventory E2 personnel conducted a review of Sanborn Insurance Maps, completed a site reconnaissance of each parcel, and reviewed aerial photographs. Because site access was not obtained for the parcels, recommendations for Brownfield eligibility was based on observations made from public rights-of-ways and available documentation.
