(a) Site Plan. An applicant must submit one set, full size (22 inches by 34 inches) and two sets, reduced to maximum size of 11 inches by 17 inches, of a site plan showing: (1) Property lines and comers and delineation of lands under ownership of the applicant. (2) Existing and proposed elevation contours, including the existing runout elevation and flow capacity of the wetland outlet, and spoil disposal areas. (3) Area of the wetland portion to be filled, drained, excavated or otherwise altered. (b) Wetland Delineation Report. An applicant must submit at least three copies of a wetland delineation report conforming to a methodology authorized for WCA use and otherwise consistent with Minnesota Board of Water & Soil Resources guidance. The following requirements /clarifications apply to submittals of wetland delineation /determination reports to the District and supplement the approved methodology and guidance: (1) Wetland delineations should be conducted and reviewed during the period of May 1 - October 15. The District may accept delineations performed outside this time frame on a case -by -case basis. The District will determine if there is sufficient information in the report and visible in the field at the time to assess the three wetland parameters (hydrophytic vegetation, hydric soils, hydrology) in relation to the placement of the wetland delineation line. If proper assessment of the delineation is not possible, the District may consider the application incomplete until appropriate field verification is possible. (2) An applicant conducting short- or long -term wetland hydrology monitoring for the purpose of wetland delineation /determination must coordinate with the District prior to initiating the study. (3) For a site with row - cropped agricultural areas, the wetland delineation report must include a review of Farm Service Agency aerial slides (if available) for wetland signatures per Minnesota Wetland Mapping Conventions for 1985 Food Security Act as Amended and Section 404 Clean Water Act or subsequent State - approved guidance. This review is to be considered along with field data and other pertinent information, and is not necessarily the only or primary basis for a wetland determination in an agricultural row - cropped area. (4) The wetland delineation report must include: (a) Items required by the Guidelines for Submitting Wetland Delineations to the St. Paul District Corps of Engineers and Local Units of Govemment in the State of Minnesota (1996) and subsequent updates. (b) National Wetland Inventory (NWI) map, Soil Survey Map, and Department of Natural Resources (DNR) Protected Waters Map of the area being delineated. (c) Results of a field investigation of all areas indicated as potential wetland by mapping sources including: NWI wetlands, hydric soil units, poorly drained or depressional areas on the Soil Survey Map, and DNR Protected Waters or Wetlands.
