Chapter 2 - Environ. Analysis & Project Planning Flashcards
Creating Civic Spaces around a pinwheel arrangement of streets, which became known as_______…..founder Austrian Architect and City Planner, Camillo Sitte
TURBINE SQUARE
city plan post Industrial Revolution, reform movement by TONY GARNIER 1917 - was_____included separate zones for residential, public, industrial, and agricultural use, linked by separated circulaiton paths for vehicles and pedestrians. Garnier’s plan was one of the first to emphasize the idea of ZONING

The________was encouraged by the Ordinance of 1785, which established the rectangular survey system of the United States. This system divided the country into a grid of 24m squares, each subdivided into 16 townships, each 6 mi on a side. These were further subdivided into 36 1 mi^2 sections.
Grid System
planning concept work at the building neighborhood, district and regional levels in dew developments as well as urban and suburban infill projects.
New Urbanism
An extension of the idea that entirely new communities can be built away from the crowding and ugliness o exisiting cities
New Town
The quality of a physical environment that gives it a high probability of evoking a strong image in the mind of a given observer ex. the hills of San Francisco
Imageability
a way of circulation along which people customarily, occasionally, or potentially move. A path may be a river street, pedestrian walkway, railroad, transit line, or rive.
PATH
- The Image of the City, Kevin Lynch
are linear elements other than paths that form boundaries between two districts or that break continuity. ex may be a shoreline, a line of buildings against a park, a wall
EDGES
The Image of the City, Kevin Lynch
are two dimensional areas that people perceive as having some common, identifying character and that they can enter.
DISTRICTS
The Image of the City, Kevin Lynch
are strategic centers of interest that people can enter. May be the intersections of paths, places where modes of transporation change, plaza, public squares, or center of districts.
NODES
The Image of the City, Kevin Lynch
similar to nodes in that they are point reference, but people cannot enter them. They are viewed from the exterior. A tower, monument, building or natural feature can be a landmark.
LANDMARKS
The Image of the City, Kevin Lynch
With this approach, each large parcel of land can have a mix of uses: residential, commercial, recreational, and open space designed with variable lot sizes and densities. Refers to new development.
PUD, (Planned Unit Development)
Refers to the number of people per unit of area. Refers to only a ratio.
Density
tend to bring people together
Sociopetal
discourages interaction or social contact
Sociofugal
claim to a personal territory, fundamental part of animal behavior (humans included)
Teritoriality
Intimate distance
6in to 18 in
personal distance
1 1/2’ to 2 1/2’ ft
social distance
4 to 12’ ft
public distance
12’ ft outward
a diverse and stimulating environment
Diversity
described a range of design elements that used the basic concepts of surveillance, territoriality, and real and symbolic barriers to reduce crime.
Defensible Space
Nearly all land development is dependent on or affected by some surrounding base of population within a geographical region.
Catchment Area
can be defined as a relatively small area in which a number of people live who share similar needs and desires in housing, social activities, and other aspects of day-today living.
Neighborhood
graphic way to show the elevations of the land in a plan view and are used to make a slope analysis to determine the suitability of the land for various uses
Contour Lines
the fraction of total precipitation that is not absorbed into the ground
Runoff Coefficient
Below all of the upper soil layers
Bedrock
Particles over 2mm in diameter
Gravel
Particles from 0.05mm to 2 mm in diameter, the finest grains just visible to the eye
Sands
Particles from 0.002mm to 0.05mm in diameter, the grains are visible but can be felt as smooth
Silt
Particles under .002mm in diameter, smooth and floury when dry, plastic and sticky when wet
Clay
have the lowest capacity and provide direct access to building sites.
Local Streets
connect local streets and arterial streets. They, of course, have a higher capacity than local streets but are usually not intended for through traffic.
Collector Streets
are intended as major, continuous circulation routes that carry large amounts of traffic on tow or three lanes.
Arterial Streets
are limited access roads designed to move large volumes of traffic between, through, and around population centers.
Expressways
roads laid out in the horizontal direction
Horizontal Alignment
