This would, according to the LCB, depend on where that sandwich board is located. From http://lcb.wa.gov/mj2015/faq_i502_advertising:

Retailers are limited to two 1,600 square inch signs bearing their business/trade name. Does this include sandwich board signs that are used to advertise specials and events, often in the entrance of the property or on the sidewalk median?

A sandwich board would be permissible as long as it is not located on the licensee’s premises and is NOT located on a publicly-owned sidewalk or other publicly-owned or operated property. Any sandwich board would not be allowed to display marijuana and/or marijuana infused products and need to comply with city/county code.

The sandwich board is on public land and right a way. Please have it removed ASAP

Reading this request for action, I don't see that it has been resolved. The last time Code Enforcement posted anything here was on July 25. I noted the sandwich board sign was still on Hwy. 305 this weekend. Does that mean that Code Enforcement has found no violation? Or has Code Enforcement not been enforcing the code? Inquiring minds want to know.

The City is working with its legal department to determine, if the city is going to enforcer RCW 69.50.369 or is WA liquor control and cannabis going to.

I drove by the 305 - Day Road intersection last week and the sandwich board sign was in the crosswalk ramp obstructing the crosswalk button. Have seen that condition several times. How is that legal for any business's sign?

The City is letting WADOT enforce RCW 69.50.369.
