Mason County Review Checklist
for a Geotechnical Report
Instructions:
This checklist is intended to assist Staff in the review of a Geotechnicai Report, The Geotechnicai Report is reviewed
for completeness with respect to the Resource Ordinance.If an item is found to be not applicable,the Report should
explain the basis for the conclusion.The Report is also reviewed for clarity and consistency.If the drawings,
discussion,or recommendations are not understandable,they should be clarified.If they do not appear internally
consistent or consistent with the application or observations on site,this needs to be corrected or explained.If
resolution is not achieved with
ith the author,staff should refer the case to the Planning Manager or Director.
