Figure 6.14Built area along coastline relative to distance from city center.
Predominant land cover within approx. 1 km of a coastline is measured for the
10 km of coastline closest to a major city, and for the next closest 40 km (20 km in
each direction) of coastline. 10 km = 6.2 mi. See Figure 6.2 caption for city
information.
[W11]The coastline closest to a city is much more built up than that somewhat fur-
ther away, with the difference being most pronounced where city and coast are close
(Figure6.14).
This suggests that clean water, natural vegetation, attractive beach areas,
and good recreation are most likely along coastlines far from a city, and in
coastline locations not directly opposite the city. Strip development between
city and nearest coastline should have major breaks to maintain regional wildlife
connectivity. Protecting coastline stretches beyond the portion closest to a city,
and avoiding dispersed coastline development, should maintain the rich natural
and societal benefits of relatively natural coastlines.
Watersupply and drainage area
[W12]In general, large cities use reservoirs for water supply, medium cities
mainly use lakes and reservoirs, and small cities use rivers, and in a few cases, streams
or groundwater(Figure6.15).
