3 JEO Consulting Group, Inc Iowa Falls, IA Wetland Investigation Report.0 EXECUTIVE SUMMARY Impact7G, Inc. (Impact7G) was retained by JEO Consulting Group, Inc to conduct an investigation of the boundaries of jurisdictional wetlands and other waters within the subject project area of the proposed railroad project generally located at Latitude: , Longitude: and within Sections 23 & 24 Township 89N Range 2W of the Iowa Falls West Quadrangle in Hardin County, Iowa (Figure ); hereinafter, referred to as the property. During the month of September 203, Impact7G identified a potential jurisdictional wetland area within the proposed project area. Based on this investigation it appears as though discharge, fill material, excavation, temporary access, and/or mechanized land clearing in waters of the United States (US) may occur. Below is a summary of findings and actions: One () potential area of jurisdictional wetlands (totaling approximately acres) was identified within the property area. Authorization, verification and final approval from the US Army Corps of Engineers (Corps) is considered warranted if there are to be potential impacts to wetlands. We recommend this report to be submitted to the Corps prior to the final design to request concurrence on Section 404 Authorization. Wetland impacts will be dependent upon final design and construction boundaries. The information and recommendations presented in this report are professional opinions based on visual observation, review of available data pertaining to the subject property, and our interpretation of available public records. The opinions and recommendations presented herein apply to the property conditions at the time of our investigation Merle Hay Rd, STE B Johnston, IA 503 (P) (F)

4 JEO Consulting Group, Inc Iowa Falls, IA Wetland Investigation Report 2 0 INTRODUCTION This project consists of professional services associated with the completion of a wetland investigation in an attempt to provide an evaluation of potential jurisdictional waters subject to protection of the Clean Water Act, Section 404 (33 U.S.C. 344). This investigation and subsequent report were completed by Mr. Jeromy Pribil and Mr. Jon Reis of Impact7G. Purpose The purpose of the project is a rail development in a currently undeveloped, residential and agricultural land area in rural Hardin County, Iowa. The applicant, JEO Consulting Group, Inc, is assisting in the development for the project and will consider the results of this wetland investigation in planning and design efforts. Discharges of dredged or fill material, excavation and mechanized land clearing in waters of the U.S. requires authorization from the U.S. Army Corps of Engineers (Corps) under Section 404 of the Clean Water Act. The actual limits of jurisdictional waters for permitting purposes must be verified by Corps regulatory staff. The wetland delineations and determinations presented in this report may be used for planning and informational purposes. Final authorization for activities in waters of the U.S. must be authorized by the Corp s District Engineer. Wetland delineations have been conducted in accordance with the Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory, 987; referred to as 87 Manual) and the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Midwest Region (U.S. Army Corps of Engineers, 200; referred to as the Regional Supplement) for non-agricultural wetlands and for agricultural wetlands, the National Food Security Act Manual, 5 th Addition (United States Department of Agriculture (USDA) Natural Resources Conservation Service (NRCS), 200; referred to as NFSAM). 2 Project Description The project study area is located approximately ½ mile southwest of Iowa Falls, Iowa, in Hardin County (Figure ) and consists of approximately 32 acres of primarily agricultural, residential and undeveloped land. The project is generally located at Latitude: , Longitude: and within Sections 23 & 24 Township 89N Range 2W of the Iowa Falls West Quadrangle. An aerial photograph showing the project study area limits is provided in Figure A preliminary conceptual map is provided in Figure Impact7G s understands that the project will include construction of a rail development. Construction of the project is expected to begin following the final planning, design, and approval of the project Merle Hay Rd, STE B Johnston, IA 503 (P) (F)

5 JEO Consulting Group, Inc Iowa Falls, IA Wetland Investigation Report JURISDICTIONAL WATERS 3. Landscape Setting The project area appears to be located in the Eastern Iowa and Minnesota Till Prairies. The area appears to be within the Upper Iowa watershed in the Beaver Creek-South Fork Iowa River and the Iowa River-Honey Creek areas. The project area is composed of primarily undeveloped, residential and agricultural land (see photos in Appendix A). 3.2 Pre-field Work Existing data sources were reviewed to assess the project area and identify potential wetlands. The data reviewed included: Preliminary project location and site plan information from JEO Consulting Group, Inc. United States Geological Survey :24,000 Scale Topographic Maps Soil Survey of Hardin County, Iowa (Figure 5) U.S. Fish & Wildlife Service National Wetlands Inventory (NWI) Map (Figure 6) Hydric Soils of Iowa List Hydric Soils of the United States List Climatological Data from USDA - NRCS (Appendix B) Precipitation Data from WeatherUnderground.com (Appendix B) All potential wetland and other jurisdictional waters areas within the property boundaries were identified for field survey using this information. 3.3 Field Conditions Field survey of the project area was completed on September 24, 203, by Mr. Jeromy Pribil and Mr. Jon Reis. In the months of August and September (August 24 to September 24, 203) the area (recorded at Iowa Falls, IA) received.39 of precipitation which is below normal compared to the 30-year averages of 38 for August and 3.6 for September (recorded at Iowa Falls, IA). Recent and historical precipitation data are located in Appendix B. The primary source of local hydrology appears to be surface water driven, though drainage and some groundwater interaction is likely due to the range in topography. The National Wetland Inventory map (Figure 6) shows wetlands in the eastern portion of the property. 3.4 Wetland Delineations Non-agricultural wetlands within the property were identified and their boundaries delineated using the Routine On-Site Determination Method defined in the 87 Manual and 200 Midwest Regional Supplement. Thirteen data forms (Appendix C) were completed. Sample site locations and delineation boundaries are shown on Figures 2 and 3. The delineation resulted in one distinct area that potentially meets current criteria for jurisdictional wetlands. Photographs of the project area are provided in Appendix A Merle Hay Rd, STE B Johnston, IA 503 (P) (F)

6 JEO Consulting Group, Inc Iowa Falls, IA Wetland Investigation Report Wetland Determinations The agricultural portions of the project area were investigated for potential wetland impacts using National Food Security Manual (NFSAM) methodology, including the Iowa Wetland Mapping Conventions. Potential wetland areas were investigated for wetland signatures and listing on the NWI maps. No potential farmed wetlands were observed in any of the slides reviewed. County soil survey maps were reviewed for the presence of mapped hydric soils. Preliminary plat map, topographic maps and Google Earth were used to confirm local topography. Wetland Determination Data Forms are provided in Appendix C. 3.6 Investigation Findings and Results The investigation revealed that potentially one wetland area is located within the project study area. Wetland PEMF consists of a total of acres of Palustrine, Emergent, Persistent, Semi-permanently Flooded (PEMF) wetlands. Table below provides additional details of the wetlands identified. Table Potential Wetland Impacts Wetland ID Wetland Type Wetland Size (Acres) PEMF PEM The Iowa River is located approximately 0.6 miles northeast of the property and appears to flow to the southeast. The Iowa River is a water of the United States and is regulated by Section 40 Drainage across the property generally flows north northeast. An unnamed pond was located on the eastern portion of the property. No other potential jurisdictional waters were identified in and/or near the project area. Actual project impacts will be dependent upon final design and construction limits. Field survey of the project area was completed on September 24, 203, by Mr. Jeromy Pribil and Mr. Jon Reis. In the months of August and September (August 24 to September 24, 203) the area (recorded at Iowa Falls, IA) received.39 of precipitation which is below normal compared to the 30-year averages of 38 for August and 3.6 for September (recorded at Iowa Falls, IA). Recent and historical precipitation data are located in Appendix B. The primary source of local hydrology appears to be surface water driven, though drainage and some groundwater interaction is likely due to the range in topography. The National Wetland Inventory map (Figure 6) shows wetlands in the eastern portion of the property Merle Hay Rd, STE B Johnston, IA 503 (P) (F)

7 JEO Consulting Group, Inc Iowa Falls, IA Wetland Investigation Report 5 0 CONCLUSIONS A total of approximately acres of potential jurisdictional wetlands were located during this investigation. Based on the preliminary project details, this project may require authorization prior to construction. Based on current regulatory thresholds (impacts greater than 0. acres of wetland impact), the project may require compensatory mitigation for wetland impacts. 0 RECOMMENDATIONS Impact7G understands that the objective of this project is a railroad development in a primarily undeveloped, residential and agricultural land in Hardin County, Iowa. To ensure timely Corps authorization, Impact7G recommends submitting this report as supplemental information to the Corps prior to the start of final design to request their concurrence on Section 404 Authorization. 6.0 LITERATURE CITED Environmental Laboratory Corps of Engineers Wetlands Delineation Manual.
