Conn. Gen. Stat. § 52-557o: Liability of land surveyors.

No action for trespass shall lie against any surveyor licensed under chapter 391 or person acting at the direction of any such licensed surveyor who enters upon land other than the land being surveyed without causing any damage to such other land in order to perform a survey, provided no such surveyor or person acting at the direction of such surveyor shall enter upon any land owned by a railroad company, as defined in section 13b-199, which is within fifty feet of a railroad track without first obtaining written permission from the railroad company, which written permission shall not be unreasonably withheld. Nothing herein shall relieve such licensed surveyor or person from liability for actual damages caused by such entry upon such other property.
