<br />Task 2.3 – Topographic Survey, Surveys, and Mapping
<br />Consultant shall work with topographic survey subconsultant to provide a boundary and
<br />topographic survey within the project limits. The ground survey shall include all pertinent
<br />features above and below ground surface and shall be on the NAD83 and NAVD88 datum. The
<br />scope of the topographic survey shall include elevation features, utility dips, site features, and
<br />boundary information.
<br />Survey Control
<br />The topographic survey subconsultant shall utilize City approved NAD83, California State Plane
<br />horizontal coordinates and NAVD88 vertical controls, or any City preferred datum as the basis of
<br />the survey. The topographic survey subconsultant shall research nearby controls and perform
<br />measurements and adjustments of all benchmarks and controls used for the project. And shall
<br />set durable control points along the project to be preserved for utilization of surveys, future
<br />phases of the project and for future construction control.
<br />Topographic Surveying and Base Mapping
<br />By means of conventional survey methods, topographic survey subconsultant shall perform
<br />design level (non-aerial) topographic surveying and mapping at all intersections lying along the
<br />project corridor, including the full intersections of 5th Avenue and 15th Avenue. The topographic
<br />survey subconsultant shall also perform topographic surveys and mapping along the full corridor
<br />between the intersections.
<br />The width of the survey shall cover the full right-of-way and approximately 5 feet beyond where
<br />accessible and 50 feet along all side streets. Items to locate shall include curbs, gutters, sidewalks,
<br />pathways, pavement, striping, fences, walls, trees, driveways, signs, poles, signals, valves, vaults,
<br />meters, hydrants, inlets, manholes and all visible utilities and features, including any USA
<br />markings (to be coordinated by design or geotech team). The topographic survey subconsultant
<br />shall perform detailed topographic surveys of curb ramps at all intersections and shall locate curb
<br />ramp details such as sidewalk, ramps, landings, expansion joints, curbs, gutters, lip of gutter,
<br />pavement cross slopes for conform, signals, boxes, poles, and other visible features. The
<br />topographic survey subconsultant shall perform measure downs to inlets and manholes that are
<br />in the intersection project footprints for invert elevation, pipe size and flow direction, including
<br />upstream and downstream structures. All topographic features shall be mapped in AutoCAD
<br />format to include full mapping, 1’ contours and 3D surface.
<br />Boundary and Right-of-Way Mapping
<br />The topographic survey subconsultant shall research record of surveys, parcel maps, subdivision
<br />maps, roadway maps, corner record cards, deeds and other recorded information to map the
