June 19, 2025 <br />Athanasia Lewis - Interim City Administrator <br />Page 2 of 7 <br />Reference: Proposal for Engineering Services Bridge 02J08 (Brian Drive Culvert) Replacement <br />WORK PLAN <br />The work required to obtain MnDOT approval/be placed in the funding queue generally includes field <br />work/site investigations, technical reports/permitting, and plan preparation. The following tasks are included <br />in the scope of this proposal: <br />Task 1: Preliminary Survey and Data Collection <br />Stantec staff will conduct a preliminary site survey and collect other available site data including as-built <br />bridge information, utility maps, property lines, easement locations and other pertinent <br />information. The site survey will include sufficient information to develop topography, roadway <br />alignment, cross sections, utility locations, control points, structure dimensions, and data for <br />hydraulic analysis such as stream profiles and cross sections for the project. <br />Stantec will also solicit quotes from geotechnical consultants to perform soil borings and a geotechnical <br />report that will be used in the design of the bridge. We anticipate that the geotechnical consultant will <br />contract directly with the City of Centerville. <br />It is not anticipated that easement will be required for this project. However, if necessary, Stantec is <br />available to assist the City in obtaining any needed easements as an authorized supplemental service. <br />Task 2: Wetland Delineation and Report <br />Stantec will conduct a Level 2 wetland delineation of the areas defined as the project area. The delineation <br />will be conducted in accordance with the Corps of Engineers Wetland Delineation Manual and Northcentral <br />Î Northeast Regional Supplement. <br />A field investigation will be conducted during the growing season to delineate all wetland boundaries within <br />the project area. The delineation shall include an investigation of hydrology, soils, and vegetation to <br />determine wetland boundaries and types. Corps data forms shall be completed for all upland and wetland <br />data collection points. GPS data collection equipment will be used to record all wetland boundaries and <br />data collection points (upland and wetland transects). Photographs of wetlands will be collected for <br />inclusion in the wetland report. Field work will be conducted under growing season conditions. <br />Following the completion of field work, a wetland delineation report will be prepared. The report will include <br />all required components as identified by the Corps/BWSR Guidance for Submittal of Delineation Reports. <br />Components include all data forms, antecedent precipitation analysis, wetland area and type data, <br />photographs, offsite data figures, wetland narrative, and wetland delineation figure. <br />Stantec will prepare the Joint Application Form, completing Parts 1, 2, 5, and Attachment A. The form will <br />accompany the delineation report in a submittal to the Wetland Conservation Act LGU (Rice Creek <br />32 <br /> <br />
