Description: A point dataset of historical test borings drilled by the WSDOT Geotechnical Office and consultants to WSDOT. This dataset has links to boring log pdfs. The borings in this dataset were drilled before the use of gINT database software. The locations of the borings in this dataset are approximate and are not implied as having any specific spatial accuracy. They were located using one of the following processes: georeferenced historical plan sheets, alignment with stationing and offset, address description or coordinates. This data should only be used as reference. The dataset is not a complete set of historical borings. Borings are continually being added project by project as needed.
Description: Linear dataset of links to historical geotechnical documents. The locations of the features in this dataset are approximate and are not implied as having any specific spatial accuracy. They were located using one of the following processes: georeferenced historical plan sheets, alignment with stationing and offset, address description or coordinates. This data should only be used as reference. The dataset is not a complete statewide set. Features are continually being added project by project as needed.
Description: <DIV STYLE="text-align:Left;"><DIV><DIV><P><SPAN>Points depict aggregate sources that have been tested by the WSDOT State Materials Laboratory and are created from data in the Aggregate Sources Approval database (ASA). The Aggregate Sources Approval database identifies aggregate sources that have been tested by WSDOT, and have been assigned a county letter code with a sequential number for that county. It should be noted that there are sources that have been tested, but not classified with a county code, and are therefore not included in the database. Also, there are sources in the database that are not currently approved for use as materials on construction projects.</SPAN></P></DIV></DIV></DIV>
