  7. How is this useful to the survey? … Think about your segment • Main land uses • Are there major parcels, or is residential? What kind? • Is it landscaped? Natural? Are there large expanses of impervious surface? Of parks? • Are their roads nearby? Who owns them? Are they sandy or swept? • What are the activities that go on in these areas? • Kids playing, people walking dogs, construction, truck/fleet management? • Are there commercial areas like stores or offices where people throw cigarette butts? Wash their cars? Feed geese? • Look behind you! • Concerned not just with the river, but direct abutters and the adjacent neighborhoods • What is the topography? Where does stormwater come from? Where does it have a chance to pick up pollutants? And what can we do to fix this?
