Johnny Tweedle, P.S.

Johnny Tweedle, P.S., also joined Harbor from Blaylock Threet Engineers in February 2015. Johnny has lead the Survey crew at Blaylock Threet since 1975. The belief’s that Johnny lived at Blaylock Threet, are the same as Harbor; we believe that land surveying is a intricate part of day-to-day engineering activities. Johnny and the survey crew have undertaken almost every type of land and route surveying task available; including land, riparian, hydrographic, control and mining surveys, and FEMA elevation certifications.
