CEQA and NEPA Environmental Compliance Services

When construction or new land-use operations will or likely will impact sensitive or protected environmental resources, project proponents must submit detailed technical documentation and impact mitigation strategies to receive project permits under the California Environmental Quality Act (CEQA), the National Environmental Policy Act (NEPA), or both. ECORP’s staff of environmental consultants work closely with project proponents to determine specific documentation requirements, the appropriate environmental consulting services needed, and how to design implementable mitigation strategies as part of our CEQA and NEPA Documentation Services. We also review third-party documentation to ensure that it is free of error and legally defensible.

Geospatial Services

Geospatial Services are an essential part of environmental permit applications and are often necessary to comply with CEQA, NEPA, and all other applicable all applicable environmental laws and regulations, including Section 404 of the Clean Water Act (CWA), Sections 7 and 10 of the Endangered Species Act (ESA), and the California Endangered Species Act (CESA). ECORP deploys state-of-the-art technology including lidar, unmanned aerial systems, and geographic information systems to collect rich site data sets. From this, we create accurate and detailed environmental impact reports that convey complex data clearly and comprehensively.

When fossils are likely to exist or are known to exist on a project site, you need an experienced provider of Paleontology Services to safely excavate, preserve and remove the fossils for safe storage and curation before you can begin construction. ECORP’s experienced paleontologists comply with all CEQA and NEPA as well as environmental regulations stipulated by the Bureau of Land Management (BLM) and other governmental agencies with oversight over paleontological resources to ensure construction permits can be granted following the removal of sensitive and protected fossils and other paleontological resources.

Construction Monitoring

Projects that have the potential to affect natural or cultural resources may receive permits that include a requirement for construction monitoring. ECORP provides qualified personnel as part of our Construction Monitoring Services to help satisfy all stipulated project requirements. Our team includes CEQA and NEPA specialists as well as field personnel that ensure that mitigation measures are complete, correctly written, and feasible before the project goes to construction and that these measures are implemented as required before, during, and after the construction process.

Whether working on a restoration-oriented project or a construction project that requires habitat mitigation, ECORP offers comprehensive Habitat Restoration, Conservation, and Land Management Services. Our in-house team manages projects through the entirety of their lifespan, conducts due diligence assessments and initial biological surveys, prepares associated permitting and permit compliance documentation throughout construction, and designs impact mitigation plans to protect sensitive, threatened, and endangered species as well as other biological and cultural resources.

Interpretation and Aesthetics

Agencies routinely require project proponents to interpret and present a project’s data to the public. ECORP’s interdisciplinary, in-house teams work together to convert complex environmental permitting data into public interpretation exhibits and displays to educate the public about existing environmental resources as part of our Interpretation and Aesthetics Services.

Cultural Resources Management

Agencies require Cultural Resources Management Services for sites that contain or could contain cultural resources above and below ground and submerged beneath the water. ECORP’s cultural resource experts identify, document, and protect cultural resources; provide tribal consultation support services; draft standard operating procedures; and build displays, trailhead markers, and other exhibits to further educate the public about existing cultural resources within California.

English-Spanish Translation

Our English-Spanish Translation Services help both English-speaking and Spanish-speaking construction crews work together for the benefit of both private and public projects. We translate English documentation into Spanish, ensuring that workers, contractors, and the public in primarily Spanish-speaking communities understand the effects of new construction and land-use operations on existing environmental and cultural resources. We also offer on-site Spanish translation services as part of our Construction Monitoring Services.

Land Use Planning

Noise and Groundborne Vibrations

Projects that will or potentially will create noise or groundborne vibrations during and following construction must satisfy federal (NEPA), state (CEQA) and local regulations as part of the environmental permitting process. ECORP offers a wide range of Noise and Groundborne Vibration Services for permitting and other purposes. This includes noise modeling and analysis for ambient, stationary, mobile, construction, and operational sources of noise as well as noise impact mitigation design.

Air Quality and Greenhouse Gas Services

ECORP provides comprehensive Air Quality and Greenhouse Gas Services to ensure that project proponents complete CEQA and NEPA-mandated Air Quality Assessments and other documentation. Our air quality experts assess ambient air quality levels before construction and model future emission increases that could be caused by construction equipment and new land-use operations. When criteria air pollutants are expected to exceed thresholds established by the federal, state, or municipal governments, we design mitigation strategies to decrease the impact of air emissions on human communities and native wildlife habitats.
