SITE INVENTORY MAPPING Flashcards
Le Groot organizes nature’s beneficial services into 4 categories:
Production, regulation, carrier, information
How does the United Nation’s Environmental Programme define sustainability?
Meeting the needs of current and future generations through integration of environmental protection, social advancement, and prosperity.
Site planning should be informed by two key factors of the site
The site context and the site character
Three basic map types
Thematic, Chart, Reference
Examples of what a reference map might be used for
Flood hazards, bathymetry, topography
Types of maps a thematic map might be used for
Elevation ranges, land use types, vegetation communities, soil suitability for building
What types of maps might a chart be best for
Aeronautical routes and airports
Nautical routes and hazards
Streets and highways
What is the first step of the site inventory process?
Building a base map
What elements are typically included in a base map?
Topographical survey, aerial imagery
What restrictions can zoning regulations impose on a site?
Building height, building site coverage, housing density
A large lot size provides opportunities for what development benefits
Variety of options, buffer zones between adjacent (potentially undesirable) areas, and increase access points
Pros and cons of a high edge-to-interior ratio
Along a highway or otherwise undesirable area the buffer would be difficult to include without taking up significant space. Lot sizes would likely be impacted. Natural features though would be an asset with more opportunities to utilize the view/proximity.
Chloropleth Maps
Thematic mapping using classes of colour to show differences in value (such as elevation, soils, population)
What are the 8 categories of slope aspect and how are they typically graphically represented?
North, North-east, East, South-east, South, South-west, west, North-west
Typically represented with shaded Chloropleth maps, using cooler colours or heavier hatching to show the cooler (I.e. North facing in Northern Hemisphere) slopes
Aspects shown in a soil inventory may include:
Acidity/alkalinity (pH), depth-to-bedrock, erosion potential, depth to seasonally high water table, permeability
Solar radiation map can be created using three main elements of mapping inventory together, what are those elements?
Slope aspect, slope gradient and vegetation
Shade diagrams are appropriate at which of the four times during the day
Mid morning (10am), noon (12pm), mid afternoon (2pm) and late afternoon (4pm)
shade diagrams should show shading during three times of year
Equinox (autumnal or spring) , summer solstice and winter solstice
In what scenario is an exotic species likely to be a successful colonizer?
When there are minimal constraints to their development and reproduction in the new habitat
What is an Ecological Niche and what factors influence it
Position of an organism within it’s community/ecosystem, determined by the area that it lives in and how it impacts the community through it’s adaptions and behaviours
How many acres in a survey section?
640 acres
Examples of physical on-site design determinants
Site character (natural or cultural), natural features (drainage, habitats, slopes), microclimate factors
Examples of regulatory on-site design determinants
Zoning codes, building codes, land development codes, design guildelines
Examples of off-site design determinants
Infrastructure, nuisances, local landmarks, Neighbourhood/regional character styles
Non-point source pollution
Categorized by having Pollutants originating from a wide area
Point source pollution
Pollution from a single identifiable source
Stadia measurement
A survey technique that uses the observed height of a 6 foot tall object to infer horizontal distance
Four site measurement skills common to Site Planning
Nominal, interval, ratio and ordinal
Scale used to sort Collections without attributes that imply rank or order
Nominal scale examples include land-use, plant communities, slope aspect
Scale used in categories were features that have graduation or rank
Ordinal scale examples include soil drainage capability, visual quality
Scale used when there is a set special quantity between units
Interval scale examples include density and terrain elevation
Measurement scale that divides one attribute value by another
Ratio scale example: slope
The site inventory will provide data and three main categories
Biological, physical, cultural
What are examples of physical attributes of a site reviewed and documented during the site inventory process
Topography, hydrology, soil, geology, microclimate
What are some biological attributes reviewed and document it during the site inventory process
Ecological, vegetation, wildlife
What are some examples of cultural attributes reviewed and document to do inside inventory process
Land-use, open space, regulations, property ownership/value, sensory perception, infrastructure
What are some examples of ecological infrastructure constraints
Aquifer recharge areas, wetlands, surface water, critical wildlife habitat
What are some examples of health or safety constraints on site
Floodplains, earthquake fault zones, areas susceptible to landslides
What are some examples of physiographic barrier constraints
Steep slopes, Highly erodible soils, shallow bedrock
What are some examples of natural resource barriers
Prime farmland, sand and gravel deposits, specimen trees, scenic views
What are some examples of historic resources constraints
Historic buildings, archeological sites
What are some examples of legal constraints on a site
Zoning codes, subdivisions ordinances, easements, deed restrictions
What are some examples of nuisances which would be constraint on a site
Noises, odors, unsightly views
Datum
Abstract coordinate system that takes a known location to locate others
Define nuisance
A nuisance interferes with one’s enjoyment by being an inconvenience or annoyance
