Listen to part of a lecture in an urban planning class.
So far in this semester we focus on major issues that city planners have to deal with, like transportation and providing affordable housing. But there are other less obvious factors that need to be considered. And these can have a significant economic impact on the city and affect the quality of life. As you remember, we began discussing one of these factors last class, the urban forest. Remember an urban forest refers to all the trees within the city, individual trees in residence yards, trees lining city streets, or trees in parks. We started talking about the idea of assigning a monetary value to trees, this can influence how many and what kinds of trees are planted. As I mentioned last class, it may seem odd to put a price tag on a tree,but many stake-holders like city officials, business owners or private citizens, they want to see a dollar figure before decisions are made about planting new trees or maintaining trees. OK.
