Narrative:

I took the local control position in a north configuration. Due to storms south of the field along final and winds favoring a south flow I decided to change to a south flow. I coordinated this change after aircraft X. There had been a bird strike prior to me taking the position. When we notified the airport of the bird strike they did not close the runway; they only said they would go out and search. The previous controller had advised two aircraft that there was a bird strike on 32L and if they still wanted to land. The visibility was 1 3/4 we couldn't switch them to the parallel. A operations vehicle came out and I was getting an aircraft off the runway. The incoming controller in charge asked me what [the operations vehicle] was doing. I looked and saw the vehicle on the runway with an aircraft on a two mile final. I sent the aircraft around. The confusion was around whether the runway was closed and it is the airports call to close the runway. The ground controller thought the runway was closed and allowed city operations onto the runway. When I realized city operations was on the runway I looked at the rid and placard and I had both in possession. To avoid further confusion put something in writing in the SOP.
