Consulting Services Agreement between City of San Leandro and March 22, 2022 NCE for Annual Street Paving 21-23 Exhibit A – Page 9 of 12 existing striping for a minimum of 25’ beyond the paving limits. Existing striping may be revised based on complete streets evaluation and / or to meet current MUTCD standards. Submittals at 30%, 70%, 100%, and Final Bid completion phases shall be provided per the following expectations: • The 30% PS&E preliminary design submittal will identify the scope of work of the project. It will depict basic street paving limits of work, preliminary pavement treatments, with tabulated pertinent geometric information and work quantity schedule tables. It should identify all permits and easements needed for the project. It will also provide a table of contents for the technical specifications and City standard details to be used. • The 70% PS&E submittal will identify all the design elements and any special details needed. It should identify potential utility conflicts or required relocations. It will incorporate design elements including layout plans of base repair locations, similar in format to the City’s Annual Overlay / Rehabilitation 2019-21 project plans, pavement treatments, right-of-way parcel lines, typical cross- sections of selected pedestrian crossings to be regraded for ADA compliance, tabulated curb and gutter repairs, and limits of work. The 70% submittal shall include information from the topographic and utility surveys from subtasks 6.1 and 6.2 described below. • 100% PS&E will complete all design information and details needed to accomplish the scope of work. Based on the project estimated cost and available budget, bid items and/or street segments may be changed to additive alternates or removed from the final bid documents. • Final Bid PS&E shall be stamped and signed by the engineer of record and be complete and ready for public bid. Design of the streets requiring rehabilitation include subtasks for topgraphic survey and utility locating as described below. Subtask 6.1 - Topographic Survey Consultant’s Project Surveyor will complete monument/control references, field investigation and field surveys sufficient to prepare a topographic mapping product for all streets stated under key assumptions. The mapping shall be compiled at an agreed upon scale with a 1’ contour interval and will be based on the City Datum. The mapping area shall be a corridor along each of the street sections between the existing back of walk to opposite back of walk, starting and stopping at the designated locations and including through the returns of the terminating streets. In the absence of an existing sidewalk, the survey will extend to 5 feet behind the curb or edge of pavement, or up to the first substantial barrier (wall, fence, etc.), whichever occurs first. Lastly, the mapping will extend 25 feet beyond the curb return up each intersecting side street. The topographic data to be collected shall include: • Cross-sections at 50’ intervals along with detailed surface topography and/or additional spot elevations as required defining the longitudinal and cross slope grade breaks. Typically, the cross section will include back of walk, top of curb, flowline and lip of gutter, pavement ¼ point (if one exists), and pavement centerline. • Survey locations for significant surface features, such as curbs, gutters, sidewalks, driveways, misc. concrete, pavement, striping, fences, surface utilities, trees, signs, street
