Special count for all our city routes getting done soon.

We are having a special count done soon because we are overburdened. My PM was talking to us city carriers last week about what to expect. He brought up not to park on the wrong side of the road to deliver to our CBUs or for packages to porches. Instead to walk across the road or do a U turn. I’ve never heard what the official word is on this. What’s the official way of delivering a package or to a CBU that is on the opposite side of the road? 1. Park on wrong side of the road? 2. Do 2 u-turns to deliver and continue on your path of travel? 3. Walk across the street?
