Expanding Grid Development Pattern
• A city is formed at the junction of two roads and laid out • growth simply follows the grid until some natural feature, limiting population or economics stop it. • ex: Philadelphia
Star Development Pattern
• revolves around the urban core and development follows radial spokes of main highways or mass transits routes. • higher density development tends to form around the spokes • lower density development between the spokes
Field Pattern Development
• Has no central focus or apparent overall organization scheme. • development takes place in an amorphous network of highways and natural feature • ex: Los Angeles
Satellite Development Pattern
• central urban core with major cores surrounding it • the central core is linked to the others with major highways • often out cores are connected with a road system called a beltway • ex: Houston
Megalopolis Development Pattern
• two or more major urban centers near each other grow together as the space between is developed. • ex: Southern California
Slope % calculation
G = ( d / L ) X 100% G = slope of land % d = vertical distance between contours ft(m) L = horizontal distance between points of a slope ft(m)
