CEQA Documentation Services

After the appropriate document has been determined, we provide management and analysis services to complete all levels of CEQA documentation:
- CEQA Categorical Exemption
- CEQA Initial Study/Mitigated Negative Declaration (IS/MND)

- NEPA Environmental Impact Statements (EIS)

How Does ECORP Review Third-Party Applicant Prepared Documents?
ECORP has over three decades of experience writing and reviewing CEQA and NEPA documents and technical reports, which is why many government agencies ask us to review documents completed by other environmental consultants.
Our third-party review of applicant-prepared documents ensures that these reports are technically sound and legally defensible before being adopted or approved by a lead agency. We also host on-site agency meetings for a more thorough review of the proposed project to better ensure third-party documents meet CEQA, NEPA, and other environmental regulations.
