Sue is a property developer. Last year, she filed her papers with the necessary authorities to develop a residential subdivision with 100 lots. Within the subdivision, she allowed for a 10 foot strip of land at the back of each lot to be used for utilities such as water, cable, electricity and the like. She decided to allow John to remove all the large rocks from the property before any houses were built.
