For the purpose of sealing printed drawings, specifications, and other appropriate documents, each landscape architect shall obtain an embossing or rubber stamp and a reproduction facsimile of the seal to be used on documents prepared by or under the supervision of a licensed landscape architect. The seal or reproducible facsimile must be applied on all original drawings to produce legible reproduction on all copies or prints made from the drawings.

(a) an original manual signature of the person who applied it; or

(b) a digital signature, which is an electronic authentication process attached or logically associated with an electronic document, must be:

(i) unique to the person using it;

(ii) capable of verification;

(iii) under the sole control of the person using it; and

(iv) linked to a document in such a manner that the digital signature is invalidated if any data in the document is changed.

(3) When the efforts of more than one licensed landscape architect combine to produce documents requiring a seal, only one licensed landscape architect will be required to affix a seal to the document.
