Project Highlights

Recent Environmental Projects


Field efforts are underway to verify mapped vegetation types within a protected area in Los Angeles County. The preliminary effort employed four-band aerial image-based vegetation classification to arrive at the generic vegetation types shown on the map.

Field collected data of purported small mammal use were uploaded to GIS. The data were then used to develop a hot-spot map that shows concentrations of this federally-listed species to aid project planners in avoiding plans that affect sensitive areas.

Protected Wildlife Habitat Use, Riverside, California


This project restores federally-listed thread-leaved brodiaea on a 3-acre area in the San Gabriel Foothills. It follows a comprehensive plan developed in conjunction with state ecologists. The work involves planting and seeding of select species and removal/control of invasive species.

Mitigation Liability for Impacts to Natural Resources from Wind Energy Projects in Mexico

Presented at AWEA 2016

Wind Energy and other types of development projects often result in negative effects on native flora and fauna. Nevertheless, comparable to permitting processes in the United States, mechanisms exist to reduce impacts on ecosystems caused by construction and operation of development projects in Mexico. Alteration (removal) of native vegetation (also referred to as a (Cambio de Uso de Suelo), requires a special study (Estudio Tecnico Justificativo or, ETJ) that provides justification for this conversion. The ETJ outlines proposed land uses and associated impacts and provides assurances that biodiversity is not compromised directly or indirectly by the action in review. The details of the requirements are outlined in Articles 117 and 118 of the Ley General de Desarollo Forestal Sustentable (General Law of Sustainable Forest Development).

Mexico's Environmental Statutory and Regulatory Framework

June 2016

This presentation is an overview of environmental regulation in Mexico. It discusses the environmental review process, timelines, and possible outcomes. The presentation discusses Mexico's General Law on Ecological Equilibrium and Environmental Protection of 1988 (Ley General del Equilibrio Ecológico y la Protección al Ambiente), which sets forth the right to a healthy environment (Article 4), promotes sustainable development of economic activities (Article 25), and empowers Mexico’s Congress to issue legislation establishing concurrent authority of the federal, state, and municipal governments, within their respective jurisdictions, to protect, preserve and restore environmental equilibrium (Article 73).

Navigating Mexico's Environmental Review Process in the Context of Recent Energy Reform

February 2015

Comparable to U.S. policy, energy developers operating in Mexico must undertake environmental assessment, permitting, and mitigation as part of project permitting. Recent landmark energy reforms end the Mexican government’s 75-year energy monopoly and open the way for foreign investment. Foreign and domestic energy developers can now participate in Mexico’s energy market and U.S.-based companies poised to capitalize on available contracting opportunities must consider compliance with a suite of applicable environmental policies and their associated costs.
