If you were issued your initial license on or after January 1, 2017, you must have a seal/stamp of the design authorized by the board, bearing your name, license number and the legend "Licensed landscape architect, state of Washington." The size of the seal/stamp may be adjusted provided it remains readable. Other deviations are not allowed. Examples of the board-authorized seal/stamp appear below.

If you were licensed before January 1, 2017, you may continue to use your existing registration stamp.

1. (1) Your seal/stamp must include your signature and your license expiration date.

2. (2) You must seal/stamp the following:

   1. (a) All technical submissions required for building permits, regulatory approvals and/or construction drawings that are filed with authorities having jurisdiction;
   2. (b) Drawings prepared by you on each sheet;
   3. (c) Specifications and other technical submissions need only be sealed/stamped on the cover, title page, and all pages of the table of contents.

3. (3) Your seal/stamp shall not be affixed to any drawings not prepared by you or your regularly employed subordinates, or not reviewed by you. If you seal/stamp drawings or specifications that you have reviewed, you shall be responsible to the same extent as if those drawings or specifications were prepared by you.

   Without exception, these sealing/stamping requirements for landscape architects shall apply to all work prepared or supervised by the landscape architect.

4. (4) The terms "signature" or "signed" as used in chapter 18.96 RCW and this chapter, shall mean the following:

   1. (a) A handwritten identification or a digital representation of your handwritten identification that represents the act of putting your name on a document to attest to its validity. The handwritten or digital identification must be:

      1. (i) Original and written by hand, or a scanned image of an original, handwritten identification;
      2. (ii) Permanently affixed to the document(s) being certified;
      3. (iii) Applied to the document by the identified licensee; and
      4. (iv) Placed adjacent to the seal/stamp of the licensee.

   2. (b) A digital identification that is an electronic authentication process attached to or logically associated with an electronic document. The digital identification may include a scanned or digitized signature. The digital identification must be:

      1. (i) Unique to the licensee using it;
      2. (ii) Capable of independent verification;
      3. (iii) Under the exclusive control of the licensee using it;
      4. (iv) Linked to a document in such a manner that the digital identification is invalidated if any data in the document is changed.
