REV: 11-07-23 SK <br />Underground Utility Locating: Consultant’s in-house utility locators <br />will perform utility investigation services using standard industry <br />acceptable method as per California Government Code section 4216 to <br />determine the approximate horizontal position and depth of detectable <br />utility lines within the 200-foot by 300-foot area described above. <br />Consultant’s field crews will use a combination of water-based paint and <br />pin flags to mark the results of the investigation on the ground surface. <br />Consultant crews may opt to use the Ground Penetrating Radar (GPR), <br />if the soil conditions will return a good signal to attempt to locate utility <br />lines with no tracer wires. Individual field conditions will dictate the <br />thoroughness of Consultant’s subsurface utility investigation. Consultant <br />will perform a reasonable effort to determine the location of the existing <br />underground utility lines; however, due to technical limitations of today’s <br />most modern equipment, no guarantee (expressed or implied) can be <br />made. Irrigation lines, empty conduits, and abandoned utilities will not <br />be located. Potholing and excavation are not included in this task, but <br />Consultant’s subconsultant BESS TestLabs is part of the Consultant <br />Team and is available to perform potholing as an additional service. If <br />necessary, Consultant will endeavor to locate abandoned lines and <br />utilities as needed under additional services. <br />Mapping: Consultant will review the title report provided by others <br />and document easements and encumbrances identified that may impact <br />design of the facility. The signed hardcopy Topographic Map will be an <br />instrument of service. Electronic mapping will be completed in an <br />AutoCAD format and can be transferred and used by others for future <br />projects. <br />The mapping is anticipated to be 1” = 10’. Consultant will take <br />a series of photographs for future reference and documentation <br />of current field conditions encountered during the time of the <br />survey. <br />The vertical control for the survey will be tied to the North <br />American Vertical Datum of 1988 (NAVD88). <br />The horizontal location and rotation of the mapping is <br />anticipated to be on California State Plane Coordinates, Zone III <br />based on the North American Datum of 1983 (NAD83). The <br />mapping will be done in ground distance. <br />Subtask 2.3 – Easements and Encumbrances <br />Consultant was provided a deed dated November 27, 1959, and a parcel <br />map dated September, 1997 of the existing pump station property. The City will <br />obtain a title report from a title company who can certify that these are the latest <br />records at the county level. Consultant will provide easements and <br />encumbrances services based on the deed (or title report) provided by the City. <br />ATTY/AGR.2023.241/BKF Engineers (Price Tract Pump Station Design) (Page 14 of 54)
