A1,03 Jurisdictional Wetland Determination (JD) In order to receive approval from the regulatory agencies a wetland delineation of Jurisdictional Determination will be required. The following Scope of Work provides a fixed scope of services for providing a wetlands delineation, not knowing the extent to which Environmental Recognized Conditions would be identified, or the size(s) and location(s) of any suspect wetland areas present on the respective parcels. Should a review of the U.S. Fish and Wildlife -National Wetland Inventory (NWI) Maps for the subject site, or visual observations made as part of a site reconnaissance identify the potential presence of wetland areas, a wetland delineation would be deemed necessary. A wetland delineation is needed to ensure these areas, if present, are identified and protected according to both state and federal laws. Our wetland delineation would adhere to the 1987 U.S. Army Corps of Engineers Field Manual in evaluating areas for the following criteria used to verify wetlands: hydrology, hydric soils and the presence of wetland vegetation. In performing the wetland delineation, Jones Petrie Rafinski would establish wetland determination points for establishing the presence or absence of such criteria. Wetland boundaries will be identified, flagged and mapped to Indiana State Plane Coordinates. This "mapping" of the potential wetland area will serve as a basis for a follow up "determination" meeting required with the Army Corp of Engineers. A written report of the field investigation will be delivered to the client upon completion of the project. Please note that completion may or may not require signature authority of one or both of the agencies regulating wetlands (State of Indiana or Army Corps of Engineers). Wetland permitting and/or mitigation planning services for wetland replacement may also be necessary depending on the investigation outcome of the area in questions. The typical timeline for permit issuance is usually in the 60 day to 90 day period depending on the work load of the respective agency, and/or the need for scheduling site visits with the regulatory agencies. A1.04 Streambank Stabilization Plans A. Upon completion of the topographic survey, The Engineer will prepare a base plan from which the Streambank Stabilization Plan will be developed. The team will utilize previously developed plans and details, to be provided by the City, to assist in the determining the appropriate streambank treatments. B. This project is to also include a pedestrian bridge to replace the existing stone bridge and is to span across Bowman Creek. The previously prepared designs call for pre-engineered composite bridge is approximately 6' wide by 20' long and will need be anchored done via helical piers or concrete bridge abutments. The Engineer is to evaluate the proposed bridge, the proposed location and how it is to be secured. Based on previous correspondences between the City and the various governing agencies special attention will be required towards the height of which this bridge is to be place. A location of a pathway from the park to the bridge will be prepared and presented to the City for consideration. C. The scope of services that will be provided during the Streambank Stabilization Plan development are as follows: Page 2
