LARE LARE Site Inventory and Analysis 4

Question 1

Which mapping method provides the most accurate existing tree canopy data for a large urban park site inventory?

Accepted Answer

LiDAR remote sensing combined with field verification

Answer

LiDAR captures three-dimensional canopy structure with high precision, and field verification confirms species identity and health status.

Question 2

A soil percolation test yields an infiltration rate of 0.5 inches per hour. What does this value suggest about the site's suitability for an infiltration basin?

Accepted Answer

Poor — the site is unsuitable without significant soil improvement

Answer

Most stormwater infiltration practices require a minimum infiltration rate of 0.5-1 inch per hour, so 0.5 in/hr is at the lower threshold, indicating poor suitability.

Question 3

During site inventory, a landscape architect identifies a historic stone wall along the property boundary. Under the Secretary of the Interior's Standards, the preferred treatment to maintain its significance is:

Accepted Answer

Preservation in place with minimal intervention

Answer

The Standards' Preservation treatment calls for stabilizing and maintaining existing historic materials with the least intervention, ideal when the resource is intact.

Question 4

A site analysis identifies a jurisdictional wetland in the southwest corner of a property, and the required 100-foot buffer would cover 40% of the buildable area. The best initial design strategy is to:

Accepted Answer

Cluster development outside the buffer and use the buffer as open space amenity

Answer

Clustering development outside the regulated buffer preserves the wetland's function, satisfies regulatory requirements, and converts the constraint into a site amenity.

Question 5

The K-factor in the Universal Soil Loss Equation (USLE) represents:

Accepted Answer

Soil erodibility based on texture, structure, and organic matter

Answer

The K-factor quantifies how susceptible a soil is to detachment and transport by rainfall and runoff, based on its physical and chemical properties.
