2017 Trail/Watermain Projects – City of Arden Hills February 9, 2017 Page 3 of 7 be impacted during construction), street signs, light poles, water surfaces, and other items as needed to assist in the design process. To the greatest extent possible, property corners will be located in the field, but a detailed boundary survey or monumentation research has not been included with this scope of services. As part of the preliminary design survey, cross sections at 50-foot intervals, as well as driveway locations, will be created using centerline, top of curb and gutter line elevations. These cross sections will be incorporated into the CAD base-mapping and used to ensure the design fits within the existing area with minimized impacts to adjoining properties. It has been assumed that the City will provide record plan information or any existing plat information for incorporation into the AutoCAD base-map and TIN. Once the project is complete, WSB will provide the City with the electronic files used on the project. Any additional survey requested by the City, or what may be needed due to changes in scope, or schedule, will require a re-evaluation of this service fee. It is expected that survey work completed by other consultants will be provided to WSB in an AutoCAD basemap format. 5. Preliminary Layout Upon authorization, we will begin preliminary work immediately by gathering private utility data, conducting a topographic survey, wetland delineation, reviewing City utility record drawings, hosting a private utility meeting, and reviewing the City’s existing drainage system. The information gathered will be used to develop preliminary design mapping and/or exhibits, and a cost estimate. Drafting of a feasibility report has not been included with the scope of work. 6. Wetland Delineation/Wetland Permitting Wetland delineations will be required along the Old Snelling Trail project north of Bethel University and along the County Road E2 trail section. WSB will complete a Level 2 (onsite) wetland investigation within the designated project limits. Wetlands and surface water features (if any) will be delineated and characterized in conformance with the US Army Corps of Engineers (USACE) Wetlands Delineation Manual (US Army Corps of Engineers, 1987) and the Northcentral/Northeast Regional Supplement. The wetland boundaries will be surveyed, the top-of-bank of watercourses will also be identified if necessary, therefore differentiating waters and wetlands, which are permitted differently. The information obtained as part of the delineation will be compiled into a wetland delineation report. This report will be submitted to Rice Creek Watershed District, the Local Government Unit (LGU), and USACE for their review and approval. The wetland delineation report will include a figure depicting the locations of all delineated wetlands, as well as characterization & classification of wetland types. The approved delineated wetland boundaries will be incorporated into the project design for wetland impact avoidance and minimization considerations. Based on a preliminary review of the proposed project alignment, it is anticipated that wetland impacts will occur. WSB will prepare the WCA, Section 404 permits application (Joint Application), and incorporate the avoidance sequencing discussion and assumed wetland replacement will be via an approved wetland bank. WSB can identify an appropriate wetland bank and coordinate the replacement credits purchase process. The cost for the purchase of the wetland replacement credits is not included in this scope, and would be coordinated separately with the City of Arden Hills. 7. Project Meetings, City Council Meetings, and Public Involvement WSB will hold project meetings with the City, Ramsey County, and Bethel University throughout the design process to ensure that this project is designed and implemented with all stakeholders in mind. These will include one kick- off meeting with City staff at the beginning of the project, one with Ramsey County, and one with Bethel University. The scope of services includes one neighborhood open house during preliminary design. In addition, WSB will
