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? Land use Notice clusters of industries, or other like land uses. Roads - What is drainage like? Are there catch-basins? Activities - Places where educational materials are appropriate? Go thru “Tips”
