HomeMy WebLinkAbout042 - Wetland Review Checklist W BOZEMAN MT Community Development WR WETLAND REVIEW CHECKLIST GENERAL INFORMATION This handout is for all activities proposed in or adjacent to regulated wetland areas. Section 38.610 BMC includes the wetland regulations for the City of Bozeman. 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 wetlands indicators for all three wetland parameters. DIGITAL SUBMITTALS & NAMING PROTOCOL 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, etc. b. The Drawings folder should include items such as site plans, civil plans, landscape plans, photometric plans, elevations, etc. 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 mode. 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 REVIEW CHECKLIST All parties applying for activity permits proposing action affecting federal, state or city regulated wetlands, watercourses and/or buffers within the city limits must submit the following information in compliance with Section 38.220.130 BMC: 1. A wetland and watercourse delineation report must be submitted to the city for all projects, if aquatic resources are present. When required to determine applicability and scope of wetland location and function the delineation shall go beyond the boundary of the property. If no aquatic resources are present, a letter must be submitted to the city stating that there are no water resources within the subject property. a. This wetland and watercourse delineation report must include, but not be limited to, the following and must in be prepared in accordance with Section 38.610.030 BMC: i. Wetland and watercourse descriptions; ii. Functional assessment, as determined by a state-accepted functional assessment method, i.e., Montana Department of Transportation (Berglund and McEldowney 2008 as amended) or Montana Department of Environmental Quality (Apfelbeck and Farris 2005 as amended); iii. Wetland types, as determined by a state-accepted functional assessment method (i.e., Cowardin et al 1979 as amended); iv. Wetland acreages (by a licensed surveyor); v. Maps with property boundaries, wetland and watercourse boundaries and acreages; and vi. Wetland data forms (U.S. Army Corps of Engineers data forms). 2. If activities are planned in and/or adjacent to aquatic resources the following information is required: a. A site plan which shows the property boundary; delineated wetland and watercourse boundaries; buffer boundaries; and all existing and proposed structures, roads, trails, and easements. The site plan will include a table of existing wetland functional ratings and acreage, required buffers and acreage, and linear feet of all watercourses and ditches. i. All direct impacts to wetlands, watercourses, and buffers must be highlighted and summarized in a table on the Wetland Review Checklist Page 1 of 4 Revision Date: November 2022 WETLAND REVIEW CHECKLIST site plan. The water resource and buffer summary table must include wetland/watercourse identification number; corresponding buffer width and acreage; total site, wetland, watercourse, ditch, and buffer acreages; jurisdictional status; impacts to all water resources and buffers; and, mitigation types and acreages. ii. All indirect impacts (e.g., shading from boardwalks or public utility well drawdown) must be summarized in the document. b. A map with all proposed mitigation areas and their required buffers. The map must include a table of mitigation wetland type and acreage and required buffers and acreage and a description of the functional unit gain of the wetland mitigation (as determined by a state-accepted functional assessment method). c. The source, type and method of transport and disposal of any fill material to be used, and certification that the placement of fill material will not violate any applicable state or federal statutes and regulations as listed in section 38.220.020. d. Copies of the following: i. Any floodplain determinations for the proposed site known to the applicant; ii. Any U.S. Army Corps of Engineers jurisdictional determinations regarding wetlands on the proposed and adjacent site; and iii. Any permits from the required permits section below e. A completed wetland review checklist. 3. If in the preparation or review of the required submittal materials it is determined that there are unavoidable impacts to wetlands and/or watercourses that will require a Federal Clean Water Act permit, then the following information must be submitted to the city for all federal jurisdictional and city-regulated wetlands (see section 38.700.210 for definition) in a compensatory mitigation report: a. The descriptive narrative must include, at a minimum: i. The name and contact information of the applicant; the name, qualifications, and contact information for the primary author of the compensatory mitigation report; a description of the proposal; summary of the direct and indirect impacts and proposed mitigation concept; identification of all the local, state, and federal wetland/stream-related permit required for the project; and, a vicinity map for the project. ii. A description of the existing wetland, watercourse and buffer areas that will be impacted including area based on professional surveys; dominant vegetation; and functional assessments and wetland ratings for the entire wetland and the portions proposed to be impacted. iii. An assessment of the potential changes in wetland hydroperiod for the proposed project and how the design has been modified to avoid, minimize or reduce impacts to the wetland hydroperiod. iv. A description of the proposed conceptual mitigation actions for wetland, watercourse and buffer areas. Provide specifications (including buffers) for all proposed mitigation for wetland/watercourse/buffer impacts. Include a map with all proposed mitigation areas and their required buffers. v. An assessment of existing conditions in the zone of the proposed mitigation including vegetation community structure and composition, existing hydroperiod, existing soil conditions, and existing wetland functions. vi. Field data that was collected to document the existing conditions of the proposed mitigation sites and on which the future hydrologic and soil conditions of the mitigation wetlands are based (e.g., hydrologic conditions: piezometer data, staff/crest gage data, hydrologic modeling, visual observations; soil conditions: data from hand- dug or mechanical soil pits or boring results). The applicant may not rely on soil survey data for establishing existing conditions. vii. A planting schedule by proposed community type and hydrologic regime, size and type of plant material to be installed, spacing of plants, “typical” clustering patterns, total number of each species by community type, timing of installation, nutrient requirements, watering schedule, weed control, and where appropriate measures to protect plants from destruction. Native species must comprise 80 percent of the plants installed or seeded within the mitigation site. Wetland Review Checklist Page 2 of 4 Revision Date: November 2022 WETLAND REVIEW CHECKLIST viii. The mitigation monitoring plan must include a period of not less than three years, and establish the responsibility for long-term removal of invasive vegetation. ix. Wetland mitigation performance criteria (measurable standards reflective of expected development goals established for each year after the mitigation site is established, i.e., “At the end of three years there will be an 80 percent survival of the planted shrubs and trees.”) for mitigation wetlands and buffers, a monitoring schedule, reporting requirements to the city, and maintenance schedule and actions for each year of monitoring. x. Contingency plans which clearly define course of action or corrective measures needed if performance criteria are not met. b.
