(1) Because the board bases its decision on the record developed by the city, county, or a state agency taking the challenged action, subpoenas shall not be authorized except in extraordinary circumstances. When allowed by the presiding officer, subpoenas shall be issued and enforced, and witness fees paid, as provided in RCW 34.05.446 and court rules.

(2) Every subpoena shall identify the party causing its issuance. Subpoenas may be issued by the board or by an attorney of record. The person issuing shall sign the subpoena. Parties desiring subpoenas to be signed by the board shall make a showing of relevance and reasonable scope of the testimony or evidence sought and shall prepare the subpoenas for issuance, send them to the board's office for signature, and, upon return, shall make arrangements for service.
