You created duplicate nodes for existing features - the south whidbey community park and the church to the north of the park.

Also - the driveway you added should be tagged as highway=service + service=driveway. unclassified is basically a rural residential road. Since the county doesn't have a road their, it's likely a private driveway. 

I fixed those errors.
