The City Council hereby declares the purpose of median islands within City streets is as follows:
A. To promote safety by separation vehicular traffic traveling in one direction from vehicular traffic traveling in the opposite direction;
B. To promote safety by providing a place of safety and respite for pedestrians while crossing City streets at intersections and other approved crossings, particularly for the elderly and disabled who may need additional time to safely cross City streets that traffic signals allow; and
C. To improve the visual appeal of City streets.
