Attach contents of requests to email:

1. The preferred document file format is Adobe PDF (.pdf).  We will also accept Word documents in .docx format. The Aquatic Resource/Consolidated Upload Excel spreadsheet must be submitted in .xlsm spreadsheet format.
2. Digital documents must have sufficient resolution to depict project details.  In order to have the highest quality documents, please convert original digital documents to PDF.  All forms that require signature must be digitally signed or signed manually, scanned and then transmitted electronically.
3. If transmitting via email, include all information as email attachments, and avoid transmitting information in the body of the email.
4. All documents (aquatic resource delineations, permit applications, endangered species biological assessment, historic properties reports, etc.) must be submitted as separate files. Do not combine all documents into one Adobe PDF or Word document file.
5. Name files based on their content. Please do not use company project numbers or acronyms as the sole basis for the file name(s).
6. Reduce file sizes to the maximum extent possible.

To facilitate sending large file sizes (greater than 10MB):

1. Use .zip files as attachments. Combine multiple files into a .zip file to compress file size prior to adding as an email attachment.

   • Smith Subdivision Application (1 of 2)
   • Smith Subdivision Application (2 of 2)
3. For submittals greater than 10MB and less than 8GB, please use the DoD SAFE (Secure Access File Exchange) https://safe.apps.mil/ .  Please contact us at DenverRegulatoryMailbox@usace.army.mil for an access code.
