Introduction to Site Planning and Landscape Architecture & Parameters of Site Selection and Analysis Flashcards
“the art of arranging structures on the land and shaping the spaces between; an art linked to architecture, engineering, landscape architecture and city planning” - KEVIN LYNCH
SITE PLANNING
3 SITE ANALYSIS FACTORS
Natural factors
Cultural factors
Aesthetic factors
the natural science that studies the Earth – its composition; the processes that shaped its surface; and its history.
GEOLOGY
rocks produced by crystallization from a liquid.
IGNEOUS ROCKS
when igneous rocks are exposed to surface and weathering reduces them to particles, these particles are moved by erosional process and deposited in layers into rivers and oceans.
SEDIMENTARY ROCKS
when sedimentary rocks are pushed to deeper levels of the earth.
Metamorphosed Rocks
is that branch of Geology that deals with the origin, nature and distribution of landforms.
GEOMORPHOLOGY
refers to the description of landforms.
PHYSIOGRAPHY
are irregularities on the earth’s surface. They are derived from volcanic, glacial, or erosional processes.
LANDFORMS
four basic geomorphologic information
- Soil Properties
- Drainage
- Topography and Slopes
- Soil Erosion
2 SOIL PROPERTIES
*COMPOSITION
*TEXTURE
refers to the material that makes up soil.
COMPOSITION
comprise 50% to 80% of the volume of the soil and form the all important skeletal structure of the soil.
MINERAL PRACTICE
varies radically in soils and usually imposes a limitation to any building structure.
ORGANIC MATTER
is the term used to describe the composite sizes of particles in a soil sample
TEXTURE
content varies with particle sizes, local drainage, topography and climate.
Water
There are 12 basic terms for texture, at the center of which is Class LOAM which is an intermediate mixture of 40% _____, 40% ____and 20% _____.
40% sand, 40% silt and 20% clay.
refers to the soil’s ability to transfer gravity water downward through:
GOOD DRAINAGE
PROCESS OF GOOD DRAINAGE
*INFILTRATION
*PERMEABILITY
*PERCOLATION
means that gravity water is not readily transmitted by the soil and soil is frequently or permanently saturated and may have water standing on it.
POOR DRAINAGE
Understanding slope forms for site design requires understanding of local geologic, soil, hydrologic, and vegetative conditions.
SLOPE ANALYSIS
is expressed graphically in terms of a slope profile, a silhouette of a slope drawn to known proportions with distance on the horizontal axis and elevation on the vertical axis
SLOPE FORM
4 basic slope forms are detectable on contour maps:
*STRAIGHT
*S-SHAPE
*CONCAVE
*CONVEX
ANGLE OF LOAM (well drained)
45° OR 35°
ANGLE OF LOOSE CLAY (saturated)
25° OR 15°
ANGLE OF BOULDERS AND COBBLES
45° OR 35°
ANGLE OF SAND (well drained)
33°
ANGLE OF SAND OR LOAM (FORESTED)
50° OR 35°
angle at which soil can be safely inclined and beyond which it will fail.
ANGLE OF REPOSE
ANGLE OF COMPACT CLAY (well drained)
65° OR 45°
BEDROCK (consolisitated)
90° OR 65°
