Site Analysis - Integration and Synthesis Flashcards
Site Inventory
provides the physical, biological and cultural data needed for this program - driven analysis.
Site Analysis
a diagnostics process that identifies the opportunities and constraints for a specific land use program.
Ecological Infrastructure Constraint Examples
Aquifer recharge areas,
wetlands,
surface water,
critical wildlife habitat
Health or Safety Hazards Constraint Examples
Floodplains,
earthquake fault zones,
areas susceptible to landslides
Physiographic Barriers Constraint Examples
Steep Slopes,
highly erodible soils,
shallow bedrock
Natural Resources Constraint Examples
Historic buildings,
Archeological Sites
Legal Restrictions Constraint Examples
Zoning codes,
subdivision ordinances,
easements,
deed restrictions
Nuisances Constraint Examples
Noises,
Odors,
Unsightly views
Suitability Analysis
is the process of determining the fitness or the appropriateness, of a given tract of land for a specified use.
A suitability analysis involves 3 steps:
- Identify suitability criteria for each anticipated land use
- Collect and map the relevant site attribute data
- Identify and map the site locations with a attribute values that meet the suitability criteria for the targeted land uses
In selecting data themes and data sources for site suitability factors:
Data - Requirement, Relevance, Reliability and Availability
Spatial Buffering may be used to locate areas:
- Natural Resources requiring protection from development (wetlands)
- Cultural Resources requiring protection from development (historic buildings)
- Hazards posing significant risks to human life and property
Site Suitability involves overlaying 2 or more attribute layers. The _________ and __________ analysis are two of the most common.
intersection and union
Union
the union of 2 sets for numbers yields a third set that contains each unique number in the two original sets.
1,3 u 2,3 = 1, 2, 3
Intersection
that are common to both original sets
1,3 u 2,3 = 3
