REV: 09-03-25 LF <br />o Prepare the topographic base map for the project. All surface features (e.g. <br />drain inlets, trees, water valves, roadway, sidewalk, curb and gutter, fence, <br />drainage channel, etc.) will be surveyed. Utility information and base <br />mapping approximately 20 feet beyond the limits of the project will be <br />included as needed for the design of the project. The survey will include <br />channel bottom and top of wall elevations at locations of both existing and <br />proposed storm drain outfall. <br />o The consultant in coordination with the City, will establish project alignment <br />stationing and survey control points. The field survey will include flow line <br />invert elevations and pipe diameter of storm drain facilities within the Project <br />limits. The consultant will provide a Control Plan sheet that will be included <br />in the Design Drawings. <br />o Assumptions and exclusions: <br />The consultant assumes that the project is within the City’s property <br />and easement limits. Review and investigation of entitlements, <br />easements, recorded maps, title reports, and encumbrances is <br />excluded from the scope of services. <br />If existing utilities are in question after the field survey, the consultant <br />may request approval from the City to contract a potholing company <br />to confirm the location and depth of utilities. This service is not <br />included in the scope of work. A written approval from the City is <br />needed to move forward with any service out of the scope of work of <br />this contract. <br />Geotechnical: Haley & Aldrich Inc., sub-consultant to Wood Rodgers, Inc., will <br />provide geotechnical engineering services to support design of the channel <br />rehabilitation improvements for the 1180 Main Street location along Redwood <br />Creek. <br />Assumptions: the need for additional geotechnical assessment of the project will <br />be based on observations of the channel during initial site visits. It is anticipated <br />based on cursory review of available historical geotechnical reports and aerial <br />imagery that additional subsurface exploration will not be necessary, and that <br />existing data can be leveraged to provide project-specific geotechnical <br />recommendations. As a result, sub-consultant (Haley & Aldrich Inc.) will perform <br />the following within the scope of services: <br />o Complete a site visit (1 day) to perform field measurements and visual <br />observation of existing conditions. <br />o Prepare a geotechnical memorandum summarizing geotechnical <br />recommendations based on the site visit and subconsultant’s review and <br />evaluation of the data included in the Langan report titled “Geotechnical <br />Investigation, 1180 Main Street, Redwood City, California”, dated March 27, <br />2019. The memorandum will include the following: <br />Introduction including site location, description, and a brief <br />background description. <br />Site geology and interpreted subsurface conditions based on existing <br />boring and Core Penetration Test (CPT) data. <br />ATTY/AGR.2025.173/Wood Rodgers, Inc.
