Geologist Licensing Board Meeting Minutes

See pages 16-19 of the June 6, 2017 Geologist Board Meeting Packet in which the Geologist Board clarifies when geologist licensing is and is not required.  Some of it sounds as though it is getting into engineering. This was brought the attention of the ASCE Seattle Section Geotechnical Group by one of our members. If you feel this topic warrants a further look or action by our group, please contact section President Ben Blanchette (

The packet for the Geologist Board Meeting on June 6, 2017 is available online here.
