LARE SECTION 2 EXAM - SITE SELECTION AND INVENTORY Flashcards

1
Q

Site Inventory (Physical Attributes)

A

  • Hydrology (drainage patterns, wetlands, aquifer recharge areas);
  • Soils (stability, erodibility, bearing capacity);
  • Geology (landforms, seismic hazards, depth to bedrock);

Q

Main Phases of a Site Analysis

A
  1. Proposal Phase - Will be what the proposal is based on and sometimes preliminary design and costs as well. As this is usually done prior to having a contract in place, it is usually performed out-of-pocket.
  2. Post Contract (a.k.a. Site Characterisation) - a more detailed investigation that is usually undertaken after some portion of site planning. Usually includes a geotechnical analysis of subsurface conditions (depth to bedrock, depth to groundwater, seasonal high water table, soil tests, and more recently environmental impacts).

Q

Cloropleth maps (Type of Thematic Map)

A

Expresses attribute data as discrete classes or categories.

Each of these intervals, or classes, is represented on the chloropleth map by a single colour or texture.

Effective ways of visually expressing important site attributes,
such as soil type, slope gradient, and land use suitability

Q

Isopleth Map (Type of Thematic Map)

A

Displays the locations and
numerical values of a single attribute.
An isopleth map of elevation might show several elevation classes, each of which represents the locations where elevations fall within equal increments.
7 maximum classes to avoid confusion

Q

Programming (4 Basic Steps)

A
  1. Initiate the project,
  2. Develop the projects’ mission and objectives
  3. Determine the project’s operational and physical requirements,
  4. Document and present the program to the client
17
Q

Sanborn map

A

A field survey map providing detailed historical info on building heights, footprints, past and present uses, and construction materials

18
Q

Comprehensive Masterplan

A

Offers Guidance for Future Development

19
Q

Choropleth Map (Aspect)

A

Typically the colder colours (darker) would be used on the northern (colder) slopes while warm (light) colours would be on the southern slopes.

20
Q

Comprehensive Plans

A

Community-level plans that show how a community intends to grow and develop, physically and economically, typically over a 20- to 30-year period.

21
Q

LIDAR - LIght Detection and Ranging

A

Because LIDAR can ‘‘see’’ through vegetation to detect subtle topographic variation
below tree and shrub canopies, these data can provide more accurate topographic
information than aerial photography and at a lower cost and within a shorter period than
a field survey

22
Q

Advantages of GIS Mapping

A
  • Ease and speed of map revision and map scale changes
  • Inexpensive production of short-run special purpose maps
  • Potentially greater mapping accuracy
  • Changes in the database are immediately reflected in digital maps
  • Spatial analysis
23
Q

A

Landform Classification

27
Q

How are Geological Units expressed on a geological map?

  • Trap sediments by ponding water
  • Slow runoff velocities
35
Q

Silt Fence

A
  • Temporary polypropylene sediment barrier placed on the slope contour to trap sediment ponding water behind it and allowing sediment to settle out
36
Q

Gravel Bag Structures

A

Temporary structures used along construction perimeters or within flow channels to trap sediments
- Bags are constructed out of burlap or polypropylene

37
Q
