Sections 38.220, 38.410, and 38.610 BMC includes the wetland and watercourse regulations for the City of Bozeman (City). The regulations provide specific guidelines and methods to identify whether an area is a wetland and to determine the boundary between wetlands and uplands. The City’s wetland regulations apply to both wetlands with direct hydrologic connection to “Waters of the U.S.” and to isolated wetlands with no direct connection to a Water of the U.S., and that exhibit positive wetland indicators for all three wetland parameters. DIGITAL SUBMITTALS & NAMING PROTOCOL All parties applying for activity permits proposing action affecting federal, state or City regulated wetlands, watercourse and/or buffers within the City limits must submit the following information in compliance with Section 38.220.130 BMC: 1.Create and submit a Planning application using the ProjectDox portal; a.After completing your Development Review Application, you will receive a Notification Letter (example) via email. Please download this document and obtain owner’s signature. Upload as a PDF to the “Documents” folder in ProjectDox. 2.The digital copies must be separated into two categories: Documents and Drawings. a.The Documents folder should include items such as application forms, narrative, response to City comments, supplemental documents, technical reports, easements, legal documents, and other applicable documents. b.The Drawings folder should include items such as site plans, civil plans, utility plans, landscape plans, photometric plans, existing and proposed topography, and other applicable plans. All drawing files must be drawn and formatted for a 24” x 36” sheet file or 11” x 17” sheet file. Plan pages shall be properly oriented in landscape layout and include a north arrow and scale. Refer to our Quick Guide for additional information; 3.Naming protocol. All files should be numbered and named according to their order listed on your provided Submittal Checklist. File names should start with a numeric value followed by the document name. The numeric value at the beginning of the file name ensures the order in which they are displayed. Refer to our Quick Guide for additional information; WETLAND AND WATERCOURSE REVIEW CHECKLIST All parties applying for activity permits proposing action affecting federal, state, or city-regulated wetlands, watercourses, and/or their setbacks or buffers within the city limits must submit the information in the tables below in compliance with Sections 38.220.130, 38.410.100, and 38.610. (subsections 30, 80, 90, and 100) of the BMC. After the parties provide the required information, the City will review it for compliance with the code. The City will confirm the information with an ‘N/A’ (i.e., not applicable) if the code does not apply to the action, a ‘Yes’ if information is adequate, a ‘No’ if missing, or an ‘Inadequate’ if the submitted material does not meet the required submission. If the review team determines that information is missing or inadequate, the City will request additional information.

The wetland delineation was completed very early in the process and then the ball field layout was carefully laid out to fit within the delineated wetlands. All but roughly 300 square feet of wetland impacts are a result of City public roadways and utilities, the majority of which had locations selected before this project developed. There are no wetland impacts proposed within Phase 1A. Project Impacts: There are no wetland impacts proposed within Phase 1A. Conclusion: The site design went through many iterations to avoid impacts to the wetlands. Special care was taken to eliminate any impacts due to baseball fields, trails or parking lots, with the one exception of needing to cross wetland #6 with an access road. With this careful design, the project meets the avoidance requirements of the UDC.
