Architecture Site Planning and Urban Design 1 — Questions and Answers
Question 1: What is a setback in site planning?
- A delay in the construction schedule
- The required minimum distance between a building and a property line or street right-of-way (Correct answer)
- A change order reducing project scope
- A recessed building entrance
Correct answer: The required minimum distance between a building and a property line or street right-of-way
A setback is the minimum required distance between a building or structure and a property line, street, or other feature, as specified by zoning regulations.
Question 2: What is floor area ratio (FAR)?
- The ratio of usable floor area to total gross area
- The ratio of total building floor area to the site area, controlling overall development density (Correct answer)
- The percentage of a floor plate occupied by structure
- The ratio of window area to floor area
Correct answer: The ratio of total building floor area to the site area, controlling overall development density
Floor Area Ratio (FAR) is the total building floor area divided by the lot area; a higher FAR means more building density is allowed on the site.
Question 3: What is site drainage and why is it important in architectural site planning?
- Removing construction debris from a site
- Managing stormwater runoff through grading and drainage infrastructure to prevent flooding and erosion (Correct answer)
- Underground utility routing
- Soil sampling for geotechnical analysis
Correct answer: Managing stormwater runoff through grading and drainage infrastructure to prevent flooding and erosion
Site drainage manages stormwater through careful grading, swales, inlets, and underground systems to prevent flooding, erosion, and water infiltration into buildings.
Question 4: In urban design, what is the 'five-minute walk' or quarter-mile radius concept?
- A fire egress calculation
- A walkability planning principle defining comfortable pedestrian distance to transit or amenities (Correct answer)
- An ADA accessibility requirement
- A construction phasing timeline
Correct answer: A walkability planning principle defining comfortable pedestrian distance to transit or amenities
The quarter-mile (approximately 5-minute walk) radius is a foundational walkability concept in urban design, representing the comfortable maximum walking distance to transit stops and daily amenities.
Question 5: What is a topographic survey used for in site design?
- Identifying underground utilities
- Mapping existing ground elevations to understand site contours and inform grading design (Correct answer)
- Documenting existing building conditions
- Assessing soil bearing capacity
Correct answer: Mapping existing ground elevations to understand site contours and inform grading design
A topographic survey maps existing ground elevations and contours, providing essential data for site grading, drainage design, and building placement.
Question 6: What is impervious surface coverage and why do municipalities regulate it?
- The percentage of a building's roof that is accessible
- The proportion of a site covered by materials that prevent water infiltration, regulated to control stormwater runoff (Correct answer)
- The density of paved roads in a district
- The fire-resistance rating of exterior cladding
Correct answer: The proportion of a site covered by materials that prevent water infiltration, regulated to control stormwater runoff
Impervious surface coverage is the portion of a site covered by pavement, roofs, and other materials that prevent rainfall from infiltrating the ground; municipalities limit it to reduce stormwater runoff volume.
