In order to change the use of a site from residential to commercial, a LA must apply for _________?
variance
Easement
right of one party to use a portion of the land of another party in a particular way, usually without compensation
Conveyance
The transfer of title to land from one person to another by deed; a document by which an interest in land is transferred from one person to another
Winter winds usually come from the….
Northwest
Friable Soil
Crumbles easily, when the soil is moist and crushes easily from gentle pressure between the thumb and forefinger
Plastic Soil
can be easily molded or deformed and remain that way
Loose Soil
does not hold together regardless of the situation, therefore it can not be crushed btw two fingers
Firm Soil
Requires an adequate amount of pressure from two fingers in order to crush it
When designing a project, a LA should be aware of
a. floor area ratio (zoning requirements)
b. easements
c. lot coverage limits

ALL
Fen
wetland fed by groundwater, dominated by peat moss, rich in mineral salts and is alkaline
Freshwater peat with basic alkaline soil
Salt Marsh
Dominated by herbaceous plant material. coastal, often related to estuaries
Bog
Freshwater peat with ACIDIC soil
Meadow
Field primarily vegetated with grass, wet for part of the year
mangrove
saltwater orbrackish
Riparian
near or usually fed by a river
Estuarine
River or stream in, on the coast out to the sea
Lacustrine
Related to a lake
Wetland banking
a process of tracking wetland and upland buffer credits that are designated for replacement of future wetland losses. These wetland credits may result from a prior replacement project with excess credits earmarked for banking, or from a wetland creation/restoration project done solely for the purpose of establishing wetland credits in the State Wetland Bank.
Shear Strength
The ability of a soil to withstand the pressure from a downhill force
Angle of Repose
maximum angle in which the slope of soil remains stable
Comprehensive Strength
soils ability to withstand compressive forces from directly opposite sides
Plastic Limit
(lower plastic) Water content at which soil passes from plastic to semi or solid state
What type of survey should be submitted to obtain building permits?
Boundary Survey
Land Survey
establish lengths and directions of boundary lines
Cadastral Survey
- maps drawn for the purpose of determining and defining land ownership and boundaries
- original survey, resurvey, or retracement of public lands within the Public Land Survey of the US for the restoration of property lines
convex slope
contour lines become increasingly farther apart with elevation
hill goes out like a dome
steeper at the bottom than the top
Concave slope
Decreasing slope (slope is becoming less steep) - bows inward
Watershed
an area where all the water that is either in the ground or flows on top of the soil drains into the same place.
made up of stream channel, floodplain, upland aras and groundwater
Cool summer winds come from the
Southwest
Closed Traverse
connection of lines that enclose an area and whose coordinates are predetermined
used for all property types except for roads and train line boudnaries (which would be an open traverse)
open traverse
traverse lines that do not return to the starting point
Aliquot Part
quarter or half division of a section of land
quadrant
division of a cartesian plane
The base plan
shows existing site. dimensions, physical features. measure from refrence point.
utility plan
show buildings mechanical systems
land use plan
set of decisions about how the land will be used and the ways to achieve desired uses
Includes:
- definition of goals
- ordering of land and human material resources
- explicit statement of the methods, organization, responsibilities, and schedule to be used
- agreed targets
The ideal riser to tread relationship should always add up to
between 24” and 26”
what type of parking allows for the most amount of parking spaces
90 degrees
A functional diagram should be utilized before a
site plan
silt
highly erodible and more likely to collect at the bottom of a slope after hard rain
fine particles of dirt
clay
smallest soil particle size
Loam
Rich soil consisting of a mixture of sand, clay, and decaying organic material
Proctor (compaction) Test
determins max density of a soil needed for specific job site.. Modified Proctor values are higher because they take into account higher densities needed for certain types of construction tests.
Perc test
Tests soil permeability and ability of soil to filter and absorb septic sewer effluent
Comprehensive plan
General guide to a community’s future growth and development. Involves population growth, requirements for water, various land use. Has specific goals and objectives
Master plan
a comprehensive guide for a communitys physical growth
Area Plan
Describes and details how specific areas should be developed within a city, neighborhood or community.
Referred to as a Specific Plan
Whats a land use plan?
A towns plans for what the land is going to be used for. (Recreation, development, waste, conservation, etc)
which area of the forest has the largest amount of flora diversity
edge
what should be added to soil to make it less alkaline
aluminum sulfate
what should be added to make soil less acidic
lime
Soil pH
The degree of acidity or alkalinity of a soil, expressed on a scale from 0 to 14, with 7.0 indicating neutrality, increasing values indicate increasing alkalinity, while decreasing values indicate increasing acidity.
higher: alkaline
lower: acidic
a site plan would be developed in this order
- client wants to develop site
- program defined
- alternate sites examined
- site inventory
Eminent Domain
The action of a government to take property for public use with just compensation even if the owner does not wish to sell.
factors that influence a land use plan
population forecast
weather outlook
attitude towards land
economic conditions
Amount of runoff is affected by several factors
- Amount of rain
- Length of time it falls
- steepness or slope of the land
- amount of vegetation in watershed
a comprehensive plan will provide guidelines for…
types of use
what to preserve
location of new development
