Our Deputy County Surveyor is California Surveyor of the Year!

Congratulations to our own Joe Morris for receiving the CEAC Surveyor of the Year Award!

Joseph Morris has been the San Luis Obispo Deputy County Surveyor since 2012. He has a bachelor’s degree from Cal Poly SLO, and prior to coming to SLO County, he was the Director of Surveying for Wallace Group for 15 years. Prior to this, Joe owned his own surveying company for five years.

Joe has been a member of CLSA for 37 years, and during that time has held the positions of Secretary/Treasurer, Vice President, President, and Director of the Central Coast Chapter. Joe has always volunteered to help in any way possible, most recently volunteering to perform field work on the Chapter’s GPS Benchmarks project for the NGS.
Joe has been a fierce advocate for monument preservation (just ask any of the engineers he has worked with!) and has probably been responsible for saving hundreds of monuments throughout the County. Joe has also been instrumental in the County’s conversion to an all-digital map review process.  Throughout his career Joe has always acted with incredible integrity and has always comported himself as a true professional. He has mentored many local surveyors and engineers in the SLO area, including the current County Surveyor.

Thank you for your exemplary service, Joe!
