13
Q
What is a PUD?
A
Although sometimes included as part of zoning regulations, PUDs are often framed as a variation of traditional zoning practices or “rezoned” special districts.
PUDs are a tract of land that is controlled by one entity and planned and developed as a single development (at once or in stages) over a relatively long period of time (generally 5-15 years). PUDs allow the consolidation of multiple parcels into a single master-planned project, often for mixed-use development. PUDs provide greater flexibility in meeting the density and land use requirements for the site as a whole and- as such- allow for the protection of environmentally sensitive areas and the creation of walkable neighborhoods, among other benefits.

The purpose of an as-built survey is to document a final built work and ensure that a project was constructed according to the construction documents. As-built surveys are generally conducted over the course of construction to fully document all site elements as they exist in the real world, and the location and nature of these site elements may differ from that shown on a landscape architect’s site plans due to a variety of factors.
46
What is the purpose of a Boundary Survey and how are they conducted?
Used to define the boundaries of a parcel of land. Boundary surveys are typically conducted before subdividing, improving, or building on land, and they are often incorporated into other scopes of survey work, including the ALTA survey. Property boundaries are described using a system of bearings established
47

80
What is percolation?
the downward movement of water in soil.
81
What is the difference between percolation, infiltration, and porosity?
Infiltration is: the process by which water on the ground enters the soil, downward movement into the soil, occurs on the surface of the soil, replenishes soil water deficiency
Percolation is: the slow movement of water through the pores in soil, the downward movement of water into the soil and rock, occurs slowly, occurs underground, replenishes underground aquifer
Porosity: refers to the character of the soil, not the movement of water. High porosity soil would have a high permeability.
82
How can you amend soil to have better permeability?

How can you reduce soil permeability
adding clay to sand soils can reduce permeability, as can the addition of peat moss or other highly absorbent organic materials.
84
What are hydric soils?
Soils with low permeability in areas subject to regular moisture are called hydric soils. They are characterized by being heavily saturated with water for prolonged saturation renders the soils anaerobic and generally results in the soils being bluish in color.

92
What is the angle of repose? How is it measured?
the maximum slope at which a loose material can be piled while remaining stable. measured between 0-45 degrees. Wet and compact materials have a higher angle of repose
93
What is soil elasticity?
ability of a soil to return to its original shape after being subjected to a load condition. Cohesive soils such as clays and silts are more elastic because of their fine particle size and water-holding capacity. Sands are less elastic.

101
What is sheet erosion?
the removal of a fairly uniform layer of soil or materials from the land surface by the action of rainfall and runoff water.
102
What soil characteristics make soil vulnerable to erosion?:
- Soil texture: Soils with a high proportion of sand particles are generally more vulnerable to erosion than those with a high proportion of clay particles. This is because sand particles are less cohesive and have less capacity to hold water, making them more prone to displacement by wind and water.
- Soil structure: Soil with poor structure is more vulnerable to erosion, as it has low stability and is easily displaced by wind and water.
- Soil organic matter: Soil with low organic matter content is more vulnerable to erosion as it has poor soil structure and reduced soil stability.
- Soil compaction: Compacted soil is more vulnerable to erosion as it has low permeability, reduced water infiltration, and reduced soil stability.
- Soil moisture: dry soils being more susceptible to wind erosion and wet soils more susceptible to water erosion. This is because dry soils have low cohesion, making them easier to displace, while wet soils have reduced stability due to saturation.
- Slope: steeper slopes being more susceptible to erosion than flatter slopes. This is because water and wind can more easily displace soil particles on steeper slopes, and there is less vegetation cover to protect the soil from erosion.
103

N (Nitrogen), P (Phosphorus), K (Potassium)
104
How does Nitrogen effect soil fertility?

105
How does Phosphorus effect soil fertility?
helps a plant convert other nutrients into usable building blocks with which to grow. (Think DOWN or FRUIT)
106
