Narrative:

A single engine (small aircraft X) approached the airport from the nne was told to enter the right downwind. Small aircraft Y approaching from the south was making a straight-in. As small aircraft X continued the downwind, small aircraft Y traffic was pointed out. Small aircraft X reported small aircraft Y in sight and was told to follow the traffic #2 and was cleared to land. Small aircraft X started base leg as small aircraft Y was about 1 mi on final. As small aircraft Y was on landing roll, small aircraft X was approaching landing threshold. Small aircraft Y was told to turn right at taxiway C (next available). Small aircraft X made base leg turn too close in to small aircraft Y. This was not realized until small aircraft Y was turning off the runway. During the occurrence ground control was coordinating an intersection departure and an aircraft was disoriented and didn't have the airport in sight. I had to issue a suggested heading to get the aircraft on final for the runway. Total aircraft worked during time on position (about 40 min) was 62.

Original NASA ASRS Text

Title: SMA LANDED ON AN OCCUPIED RWY.

Narrative: A SINGLE ENGINE (SMA X) APCHED THE ARPT FROM THE NNE WAS TOLD TO ENTER THE RIGHT DOWNWIND. SMA Y APCHING FROM THE S WAS MAKING A STRAIGHT-IN. AS SMA X CONTINUED THE DOWNWIND, SMA Y TFC WAS POINTED OUT. SMA X REPORTED SMA Y IN SIGHT AND WAS TOLD TO FOLLOW THE TFC #2 AND WAS CLRED TO LAND. SMA X STARTED BASE LEG AS SMA Y WAS ABOUT 1 MI ON FINAL. AS SMA Y WAS ON LNDG ROLL, SMA X WAS APCHING LNDG THRESHOLD. SMA Y WAS TOLD TO TURN RIGHT AT TXWY C (NEXT AVAILABLE). SMA X MADE BASE LEG TURN TOO CLOSE IN TO SMA Y. THIS WAS NOT REALIZED UNTIL SMA Y WAS TURNING OFF THE RWY. DURING THE OCCURRENCE GND CTL WAS COORDINATING AN INTXN DEP AND AN ACFT WAS DISORIENTED AND DIDN'T HAVE THE ARPT IN SIGHT. I HAD TO ISSUE A SUGGESTED HDG TO GET THE ACFT ON FINAL FOR THE RWY. TOTAL ACFT WORKED DURING TIME ON POSITION (ABOUT 40 MIN) WAS 62.
