Surveying method for determining site boundaries |
traversing |
|
|
leveling definition and purpose |
determining the elevations of certain points or arbitrary points typically used to determine of the topography of a site |
|
|
Chaining |
process for taking vertical measurement typically used on extremely hilly sites |
|
|
2 major divisions in a US land survey |
baseline and meridian |
|
|
elements include in a survey by a licensed surveyor |
contour lines with high and low points limits of water, including lakes and streams property lines with bearings and distances |
|
|
Backsighting |
the process by which a surveyor references a known point such as a benchmark point on a curb, a building floor elevation, or possibly a manhole cover |
|
|
benchmark |
the point to which a surveyor backchecks |
|
|
Things NOT included in site inventory and analysis |
cost of a site |
|
|
Township and Range relationship to Meridian and Baseline |
Township - measured north and south of the baseline Range - measured east and west of the principal meridian |
|
|
Chlorosis |
plant condition caused by iron deficiency symptoms: yellowing of leaves while veins remain green causes: iron becomes tied up in soil due to high pH or low pH |
|
|
mildew |
fungal problem characterized by white powdery growth on the tops and sometimes bottoms of leaves |
|
|
leaf spot |
the appearance of dark brown spots on leaves in concentric zones of discoloration |
|
|
fasciation |
a disorder that cam to uses a single stem to appear as if it were several stems fused together caused by frost, insect, or physical damage to a stem early in its development |
|
|
too much Nitrogen affect on plant roots |
too much nitrogen will burn a plants roots and kill the plant without changing its leaf color |
|
|
Over watering affect on plants |
causes roots to rot and therefore kills the plant |
|
|
Roads classification by traffic volume (arterial, collector, local, cul-de-sac) |
1. Arterial - provides for large volumes of traffic to flow with minimal stops 2. Collector - gathers traffic from several local roads and directs traffic toward arterials 3. Local - residential streets 4. Cul-de-sacs - residential streets with very limited traffic volume |
|
|
physiography |
the study of physical features of the earth's surface |
|
|
terrain |
the physical features of a tract of land |
|
|
Phase Environmental site assessment activites |
1. historical review 2. local environmental oversight agency reviews 3. government environmental database review 4. inspection of subject property and surrounding areas 5. conclusions regarding the presence or potential presence of environmental liabilities at the subject property 6. recommendations |
|
|
hydric soil |
a highly saturated soil where little or no usable oxygen is present (anaerobic) |
|
|
High water table impact on building siting |
indicates that there will be drainage problems and possible wetland conflicts *important consideration, above soil type and slopes |
|
|
pH greater than 7 indicates what type of soil |
alkaline 8.5 and above - strongly alkaline 8.0-7.0 - slightly alkaline 8-8.5 -medium alkaline |
|
|
pH less than 7 indicates what type of soil |
acidic 7-6.0 -slightly acidic 6-5.5 - medium acidic 5.5 and below - strongly acidic |
|
|
gross density = |
(no. of units)/total site area = Du/ac expressed in dwelling units per acre |
|
|
most appropriate building siting arrangement for steep slopes (greater than 8%) |
linear system - allows for minimal grading |
|
|
soil additive to improve aeration |
gypsum |
|
|
Site processes (constantly changing) affected by topography |
flora and fauna hydrology and climate geology and soils |
|
|
fen |
wetland that receives nutrients from groundwater and has non acidic peats |
|
|
quadrangle maps show: |
topography of general wetland areas, lakes and streams township range and section info new construction since the last printing |
|
|
map that illustrates a city's various districts and is used to control population densities and growth characteristics |
zoning map |
|
|
most productive type of ecosystem |
wetlands (tidal or ocean influenced most productive and most sensitive of all wetlands) |
|
|
successful urban spaces include these elements: |
water (provides background noise and has calming effect) availability of food people |
|
|
northern climates should utilize which direction for sun exposure |
south west |
|
|
building entry should be convenient to: |
parking |
|
|
best erosion control for heavily eroded areas |
rip rap - rock that has been crushed or broken to form sharp-angled edges that help with inter-locking and maintaining better connectivity when sheer forces are applied. can protect against sheer forces such as ice and quickly flowing water |
|
|
erosion control methods for partially bare slopes |
erosion control mat - helps establish vegetation jute rolls |
|
|
factors that influence amount or volume of runoff |
1. size of the watershed and amount of water entering and leaving the watershed amount (ie. smaller the watershed, the less water will be collected) 2. amount of rainfall (more water entering the watershed, the more water collected. 3. storm drainage capacity (not enough capacity =more runoff) |
|
|
factors that influence rate of runoff |
site slope surface type |
|
|
criteria used to delineate a wetland |
soils vegetation hydrology length of time water is present |
|
|
wetland banking |
conversion of wetlands once drained by farmers or wetlands of low quality into enlarged, planted, functioning wetlands (preservation, enhancement, restoration, or creation of a wetland) |
