o Provide aerial photography at scales of '1"=200' <br /> and 1"=400' <br /> <br /> o Establish survey control on aerial targets for <br /> mapping control and for future use in gathering <br /> data for design. Horizontal control will be based <br /> on the California State Plane Coordinate System, <br /> Zone 3. The vertical control will be based on the <br /> National Geodetic Vertical Datum of 1929 (sea <br /> level datum). <br /> <br /> o Mapping will be compiled at a scale of 1"=50' with <br /> a 1-foot contour interval and in conformance with <br /> Caltrans' standards and design requirements. <br /> <br /> o Prepare drafted topographic base sheets to be used <br /> for the Geometric Base Maps and Layout plans for <br /> Preliminary P,S&E. The Scale will be 1"= 50' with <br /> a 1-foot contour interval. <br /> <br />Task 3-6: Surveying <br /> <br />Determine availability of Caltrans and U.S.C. and G.S. monu- <br />ments. Both the horizontal and vertical survey controls for <br />the aerial targets for the mapping will be completed. Also, <br />a topographic survey will be performed to supplement the <br />topographic basemapping where necessary. This topographic <br />survey will include such things as inverts and top of grates <br />of drainage inlets, flow lines of ditches where necessary, <br />trees, etc. The surveys will be tied to either Caltrans or <br />U.S.C. and G.S. monuments where possible. The survey rates <br />will be prepared in a format acceptable to Caltrans and for <br />use in Resident Engineer's File. <br /> <br /> 12 <br /> <br /> <br />
