Site Planning + Design Flashcards
Development term that refers to the geographic region and population from which a facility attracts visitors/customers. (ex. a neighborhood from which the customers of supermarket resides)
Catchment Area
Ratio of people to the land, but excludes streets, open spaces and parks (could total as much as 25% of the overall site)
Net Density
Ratio of people to land , but includes everything such as streets, open spaces and parks
Gross Density
Normal conversation from 3 feet away (in dB)
60-65 dB
City traffic from inside a car (in dB)
85 dB
Level at which short term exposure can cause permanent damage (in dB)
140 dB
Densely packed units are grouped around shared common public space (residential)
Clustering Development
Legal term used to describe the cluster concept, and can be used for residential, commercial or industrial developments
Planned Unit Development (PUD)
Federally funded programs, these are a type of Planned
Unit Development that involves rehabilitating an existing (often urban) property.
Urban Redevelopment/Urban renewal
Slope Calculation
g=V/H (100)
g: grade or slope
V: rise/vertical run
H: run/horizontal distance
Angle between the sun and the horizon
Azimute
Measure of the reflectivity of a material
Albedo
Material’s ability to absorb light
Conductivity
Type of trees ideal for providing shade in Summer, but allows the warming sun pass through the branches and warm the building
in the Winter.
Deciduous Trees
Type of tree that does not shed their leaves, making them perfect for areas where you want a year-round wind break.
Conifer trees (needle leaf evergreens)
Soil Types
- Gravel: drains well, able to bear loads
- Sand: drains well, good foundation when graded
- Silt: stable when dry or damp, not wet. Swells when frozen
- Clay: plastic when wet, stiff when dry. Poor drainage, very expensive
Soil levels
- Level A: Topsoil, essential for growth of plants and takes a long time to develop
- Level B: Minerals, it lies below the plants’ roots and contain minerals, it can support life.
- Level C: Weathered and fractured rock with little biological activity
- Level D: Solid Bedrock
Laboratory method of experimentally determining the optimal moisture
content at which a given soil type will become most dense and achieve its maximum dry density
Proctor compaction test
A test to determine the absorption rate of the soil for a septic or “leach field.” The
results of this test are needed to properly design the septic system.
Percolation test
Location of frost line
Top of footings should be at or below the frost line (which avoids damage to the foundation due to moisture changes int he soil throughout the year)
A holding pond or catch basin that prevents excessive storm water runoff on a site from overloading the storm sewer system by temporarily holding the water and releasing it at a controlled rate
Retention pond
Construction designed to allow sediment to settle while water drains into the ground
Bioswale
A schedule technique that identifies specific individual tasks within a project and their relationship among one another
Critical path method
Multilane roads in each direction with parking lanes separated by a planting median or wide planting areas in both sides. Has right of ways 100-130 ft.
