Step 4Prep your sidewalk.

A few weeks before your planting date, you will be asked to mark your desired tree location on the sidewalk with chalk. They will then have the underground service companies mark your sidewalk noting location of gas lines, water pipes, etc. This is the moment of truth because they may tell you that, sadly, you don't actually have enough room to plant or there's some other problem, like buried cables for the cable cars, that means that you can't plant. If you discover that you can't plant a tree in front of your home after all, get a beer, calm down, and then ask FUF to recommend other ways to green your street. All hope is not lost. In fact, helping your neighbors plant a tree means you still get to walk by and say, "I did that." (If you won't be planting, you'll get your money back.)
Assuming there's nothing wrong with your planting area, a contractor will come by later that week to cut the sidewalk so that you'll have a place to put the tree. They may also auger the hole, which means sticking a big drill in the concrete. Bring out your camera, set up a lawn chair and enjoy the action.
