Sprinklers, Dog Fence, Sump Pump?

I have a sprinkler system, dog fence, sump pump, or another underground item. What do I need to do to make sure these are not affected by construction? 

It is essential that you notify us of these items in advance so that we can take steps to avoid them. They can be marked with either landscaping flags or landscape-safe paint. Please use pink paint. The flag colors listed below are for utility purposes.
