Gilbert, Kelly & Couturie, Inc – Most Acknowledged Land Surveying Firm In The Area

In 1921, our company began as Gilbert & Kelly, with Errol E. Kelly and Horatio L. Gilbert at the helm. In 1968, Mr. James H. Couturie joined the ranks and we incorporated as Gilbert, Kelly & Couturie, Inc. Then in 1977, Mr. Everett V. Treigle, Jr., also a registered professional land surveyor, became a partner of the firm. Until their respective deaths, this combination of professionals successfully operated the business throughout the New Orleans Metropolitan area, building our knowledge, files, and experience into one of the most acknowledged land surveying firms in the area.

In 2013, the company enlisted long-time employees, Louis C. Hartmann, Robert D. Quin, Debra S. Giordano, and Clint M. Simoneaux as shareholders of the company and in 2015, those named became the owners/partners of the firm. Mr. Hartmann (President) and Mr. Simoneaux are registered professional land surveyors. Mr. Quin (Vice President) is the Field Manager/Supervisor and Ms. Giordano (Secretary-Treasurer) is the CFO and Office Manager.

How To Contact Us


Residential and Commercial Services


Our expert team conducts property surveys for construction projects from the start of construction until the final inspections. We work with precision and attention to detail to supply accurate horizontal and vertical controls for projects, ensuring they are built to plan and specification requirements.

Our land surveyors provide these services before construction begins and also offer post-construction verification surveys to document conditions and locations of property improvements.


We also provide boundary services in southern Louisiana for municipal, commercial, and residential properties. We locate the limits of property ownership according to title documentation for any requested reason and conduct these services before the sale of a property or the start of a construction project of large or small scale.


Gilbert, Kelly, & Couturie, Inc. also provides survey for flood elevation certificates and surveys, which are used to certify building elevations used to determine the necessary flood insurance premium rate for the property.

Due to southern Louisiana’s close proximity to the Gulf of Mexico, the risk of flooding during severe weather such as thunderstorms and hurricanes is high for most properties, making flood insurance and accurate elevations essential to protecting land, homes, and commercial buildings.
