Question 1Environmental & Contextual Conditions

In the northern hemisphere, which building orientation generally provides the best opportunity for passive solar heating in winter while allowing summer sun to be shaded?

  1. Long axis north-south, with primary glazing facing west
  2. Long axis east-west, with primary glazing facing north
  3. Long axis north-south, with primary glazing facing east
  4. Long axis east-west, with primary glazing facing south Correct answer.

Explanation

In the northern hemisphere, a south-facing exposure receives direct sun throughout the day in winter, when the sun is low. A properly sized overhang can block the higher summer sun. East and west exposures receive low-angle sun that is difficult to shade.

Question 2Environmental & Contextual Conditions

On a topographic map, what does a series of contour lines spaced closely together indicate?

  1. A property boundary
  2. A steep slope Correct answer.
  3. A nearly level area
  4. A depression

Explanation

Contour lines connect points of equal elevation. Where they are close together, elevation changes rapidly over a short horizontal distance, indicating a steep slope. Widely spaced contours indicate gentler slopes.

Question 3Environmental & Contextual Conditions

A local zoning code requires a 25-foot front setback. This dimension typically controls the distance from the front property line to what?

  1. The rear wall of the building
  2. The centerline of the adjacent street
  3. The nearest off-street parking space
  4. The closest point of the building or structure Correct answer.

Explanation

A front setback is the minimum horizontal distance from the front lot line to the nearest building wall or projection. It creates a front yard and separation from the street. It does not regulate parking spaces or the street centerline.

Question 4Environmental & Contextual Conditions

What is the primary function of a bioswale in a site stormwater design?

  1. To increase the rate of runoff leaving the site
  2. To treat sewage from the building
  3. To slow, filter, and infiltrate runoff Correct answer.
  4. To store potable water for irrigation

Explanation

A bioswale is a vegetated channel that slows runoff, promotes infiltration, and filters pollutants through soil and plants. It is a stormwater management facility, not a potable water or sewage system.

Question 5Environmental & Contextual Conditions

Under the ADA Standards, what is the maximum running slope for an accessible route that is not a ramp?

  1. 1:20 (5 percent) Correct answer.
  2. 1:12 (8.33 percent)
  3. 1:8 (12.5 percent)
  4. 1:50 (2 percent)

Explanation

ADA Standards limit the running slope of an accessible route to 1:20 (5 percent). A route steeper than that is considered a ramp and must meet additional requirements for handrails, landings, and edge protection.

Question 6Environmental & Contextual Conditions

The base flood elevation (BFE) shown on a FIRM corresponds to which flood event?

  1. The flood with a 10 percent chance of occurring in any year
  2. The flood expected during a 25-year storm
  3. The highest recorded flood of the past 100 years
  4. The flood with a 1 percent chance of occurring in any year Correct answer.

Explanation

The base flood, also called the 1-percent-annual-chance flood or 100-year flood, has a 1 percent probability of being equaled or exceeded in any given year. The BFE is the water surface elevation for that event.

Question 7Environmental & Contextual Conditions

Which soil condition is most likely to require special foundation design because of volume change with moisture?

  1. Clean gravel
  2. Well-graded sand
  3. Bedrock
  4. Expansive clay Correct answer.

Explanation

Expansive clays swell when wet and shrink when dry, producing volume changes that can crack foundations and slabs. Foundations on such soils often require special design, such as deepened footings or removal and replacement.

Question 8Environmental & Contextual Conditions

Xeriscaping is a landscape approach primarily intended to do what?

  1. Maximize turf area for recreation
  2. Replace all plants with artificial turf
  3. Reduce irrigation demand through plant selection Correct answer.
  4. Increase irrigation demand for ornamental plants

Explanation

Xeriscaping uses drought-tolerant plants, efficient irrigation, and appropriate soil and mulch to reduce outdoor water demand. It is not about maximizing turf or eliminating all vegetation.

Question 9Environmental & Contextual Conditions

A fixed overhang above a south-facing window in a northern-latitude climate is most effective when it is sized to do what?

  1. Block high summer sun and admit low winter sun Correct answer.
  2. Block both summer and winter sun equally
  3. Admit summer sun and block winter sun
  4. Block low winter sun while admitting high summer sun

Explanation

In summer the sun is high, so a correctly sized overhang shades south glazing; in winter the sun is low, so sunlight passes beneath the overhang. This seasonal difference is the basis of passive solar control.

Question 10Environmental & Contextual Conditions

To reduce winter heating loads from prevailing winds, where should an evergreen windbreak be placed on a site in a cold climate?

  1. Along the south facade, directly against the wall
  2. On the windward side, upwind of the building Correct answer.
  3. On the downwind side, close to the building
  4. At the lowest point of the site to block drainage

Explanation

A windbreak is most effective when placed on the windward side, perpendicular to prevailing winter winds, so it slows the wind before it reaches the building. Effective shelter extends downwind for several tree heights.

Question 11Environmental & Contextual Conditions

A shallow vegetated swale is proposed along the uphill edge of a building pad. What is the most appropriate alignment?

  1. Directly down the steepest slope
  2. Parallel to the building's longest wall
  3. Across the property line into the neighboring lot
  4. Along a contour, sloping gradually to a discharge point Correct answer.

Explanation

A swale should follow a contour or a gentle grade so water moves slowly without eroding the channel. A gradual longitudinal slope leads runoff to a controlled discharge point. Running straight down a steep slope would accelerate erosion.

Question 12Environmental & Contextual Conditions

Using the ADA Standards, what is the minimum number of accessible parking spaces required for a lot with 100 total spaces?

  1. 2
  2. 1
  3. 3
  4. 4 Correct answer.

Explanation

The ADA Standards table requires one accessible space for 1-25 total spaces, two for 26-50, three for 51-75, and four for 76-100. A 100-space lot therefore requires four accessible spaces, at least one of which must be van accessible.

Question 13Environmental & Contextual Conditions

A zoning district allows a floor area ratio (FAR) of 2.0. On a 15,000-square-foot lot, what is the maximum gross floor area permitted?

  1. 30,000 square feet Correct answer.
  2. 15,000 square feet
  3. 45,000 square feet
  4. 7,500 square feet

Explanation

Floor area ratio is the ratio of gross floor area to lot area. Multiplying the lot area by the FAR gives the maximum permitted floor area: 15,000 square feet × 2.0 = 30,000 square feet.

Question 14Environmental & Contextual Conditions

A utility easement crosses a development site. What does this generally mean for the property owner?

  1. The owner keeps title but must allow access and limit building Correct answer.
  2. The easement automatically transfers to the adjacent property owner
  3. The owner may build any structure within the easement
  4. The utility company owns the fee title to the easement strip

Explanation

An easement grants a right of use over another's land without transferring fee ownership. The property owner keeps title but must allow utility access and usually cannot build permanent structures within the easement.

Question 15Environmental & Contextual Conditions

A site previously used as a dry cleaner is suspected of soil contamination. Which term best describes this property?

  1. A brownfield Correct answer.
  2. A greenfield
  3. A conservation easement
  4. A wetland

Explanation

A brownfield is property whose expansion, redevelopment, or reuse may be complicated by the presence or potential presence of a hazardous substance or pollutant. Former dry cleaners are a common example because of solvent use.

Question 16Environmental & Contextual Conditions

Which site design strategy most directly reduces the urban heat island effect?

  1. Increasing asphalt paving area
  2. Installing high-albedo paving and shade trees Correct answer.
  3. Using dark, low-albedo roofing materials
  4. Removing street trees to improve solar exposure

Explanation

High-albedo surfaces reflect more solar radiation, and shade trees reduce surface and air temperatures through shading and evapotranspiration. Together they directly lower heat buildup in developed areas.

Question 17Environmental & Contextual Conditions

Which exterior lighting approach best limits light pollution and skyglow?

  1. Higher mounting heights with wide beam spread
  2. Unshielded wall-pack fixtures
  3. Full cut-off fixtures aimed downward Correct answer.
  4. Up-lighting of facades and signs

Explanation

Full cut-off fixtures shield the light source so that light is directed downward onto the task area. This reduces uplight, light trespass, and skyglow. Unshielded and uplighting strategies increase light pollution.

Question 18Environmental & Contextual Conditions

Under the Clean Water Act, which permit is typically required before placing fill material into a wetland?

  1. A Section 106 historic review
  2. A National Pollutant Discharge Elimination System permit
  3. A Clean Air Act permit
  4. A Section 404 dredge and fill permit Correct answer.

Explanation

Section 404 of the Clean Water Act regulates the discharge of dredged or fill material into waters of the United States, including many wetlands. A permit is typically required before fill is placed.

Question 19Environmental & Contextual Conditions

During construction, where should a silt fence be installed to control sediment?

  1. In the middle of the site near equipment
  2. Along the downslope edge of the disturbed area Correct answer.
  3. At the top of the slope above disturbed soil
  4. Directly over a storm drain inlet

Explanation

A silt fence is installed along the downslope perimeter of disturbed areas to intercept sediment-laden runoff before it leaves the site. It should be entrenched and maintained until the area is stabilized.

Question 20Environmental & Contextual Conditions

Transit-oriented development (TOD) generally seeks what relationship between land use and transit?

  1. Mixed-use, higher-density development near stations Correct answer.
  2. Low-density, single-use development near stations
  3. Large surface parking lots between stations and buildings
  4. Industrial uses that rely on truck access near stations

Explanation

TOD concentrates higher-density, mixed-use development within easy walking distance of transit stations, reducing dependence on automobiles. Surface parking and low-density single-use patterns work against that goal.

Question 21Environmental & Contextual Conditions

At solar noon on the summer solstice at 40 degrees north latitude, what is the approximate solar altitude?

  1. 26.5 degrees
  2. 90 degrees
  3. 50 degrees
  4. 73.5 degrees Correct answer.

Explanation

Solar altitude at noon on the summer solstice is approximately 90° minus latitude plus 23.5°. At 40° north, that is 90 − 40 + 23.5 = 73.5°. On the winter solstice it would be about 26.5°.

Question 22Environmental & Contextual Conditions

Permeable pavement is least appropriate in which site condition?

  1. High water table with clay soils Correct answer.
  2. A low-traffic pedestrian plaza
  3. A parking lot with light vehicle loads
  4. A walkway with sandy subgrade

Explanation

Permeable pavement relies on infiltration into the subgrade. A high water table and clay soils provide little storage or infiltration capacity, so the system may not perform and could freeze or clog. It is better suited to sandy, well-drained soils.

Question 23Environmental & Contextual Conditions

Two tall buildings are placed close together with their long sides facing each other. What microclimate effect is most likely in the space between them?

  1. Increased solar gain from reflection
  2. Reduced wind speed from sheltering
  3. Accelerated wind from channeling Correct answer.
  4. Lower air temperature from shading

Explanation

When wind is forced between two closely spaced tall buildings, it can accelerate through the gap, a phenomenon often called channeling or the venturi effect. This can create uncomfortable and even hazardous pedestrian conditions.

Question 24Environmental & Contextual Conditions

A site plan proposes a tall building that would shade a neighboring roof-mounted solar array in winter. Which analysis is most appropriate to evaluate this impact?

  1. A traffic impact study
  2. A contour map of existing grades
  3. A soil boring log
  4. A winter solstice shadow study Correct answer.

Explanation

A solar shadow study models sun angles at specific dates and times to show whether a proposed building would shade existing solar collectors. Winter solstice is critical because sun angles are lowest and shading impacts are greatest.

Question 25Environmental & Contextual Conditions

A hillside site requires a balanced cut-and-fill grading plan. What is the primary goal of balancing cut and fill?

  1. Maximize the amount of soil exported from the site
  2. Minimize soil hauling and site disturbance Correct answer.
  3. Raise the building pad above all existing contours
  4. Create the steepest possible finished slopes

Explanation

Balancing cut and fill means the amount of soil excavated equals the amount needed for fills, so little or no soil must be imported or hauled off. This reduces truck traffic, cost, and site disturbance and supports better stormwater management.

Question 26Environmental & Contextual Conditions

On a topographic survey, contour lines that are spaced closely together indicate which site condition?

  1. A nearly level area
  2. A steep slope Correct answer.
  3. A uniform gradient
  4. A seasonal drainage channel

Explanation

Contour lines connect points of equal elevation, so the horizontal distance between them represents how quickly elevation changes. Closely spaced contours mean a large elevation change over a short distance, which is a steep slope.

Question 27Environmental & Contextual Conditions

What does a Phase I Environmental Site Assessment primarily involve?

  1. Excavation and disposal of contaminated soil
  2. Laboratory analysis of soil and groundwater samples
  3. A records review and visual inspection of the property Correct answer.
  4. Installation of monitoring wells to track contamination

Explanation

A Phase I assessment is a non-intrusive investigation that reviews historical records, regulatory databases, and site conditions to identify recognized environmental conditions. Sampling and testing belong to a Phase II investigation, which follows only if the Phase I identifies a concern.

Question 28Environmental & Contextual Conditions

What is the primary purpose of a stormwater detention basin?

  1. To store runoff temporarily and release it at a controlled rate Correct answer.
  2. To treat sanitary sewage before discharge
  3. To eliminate the need for site grading
  4. To hold a permanent pond for aquatic habitat

Explanation

Detention facilities attenuate peak flows by holding stormwater briefly and releasing it slowly through a controlled outlet. This reduces downstream flooding and erosion caused by new impervious surfaces.

Question 29Environmental & Contextual Conditions

Under the ADA Standards, an accessible route with a running slope steeper than which ratio must be designed as a ramp?

  1. 1:12
  2. 1:16
  3. 1:20 Correct answer.
  4. 1:8

Explanation

The ADA Standards treat any walking surface with a running slope steeper than 1:20, or 5 percent, as a ramp. Ramps then carry additional requirements such as handrails, landings, and edge protection.

Question 30Environmental & Contextual Conditions

A percolation test performed on a site measures which soil property?

  1. The bearing capacity under a footing
  2. The depth to bedrock
  3. The rate at which soil absorbs water Correct answer.
  4. The shrink-swell potential of clay

Explanation

A percolation test measures how quickly water moves through the soil, which governs the sizing of septic absorption fields and infiltration-based stormwater practices. Bearing capacity and depth to bedrock come from borings and test pits, not percolation tests.

Question 31Environmental & Contextual Conditions

In a cold climate where winter winds arrive from the northwest, where should the main building entrance ideally be located?

  1. On the west side, facing the street
  2. On the northwest corner, sheltered by a canopy
  3. On the southeast side, away from the winter wind Correct answer.
  4. On the north side, adjacent to parking

Explanation

Entrances placed on the leeward side reduce wind-driven heat loss and improve comfort for people entering and leaving. In a cold climate the entrance is best kept away from the face that receives prevailing winter winds, while also collecting useful solar gain.

Question 32Environmental & Contextual Conditions

Which practice best protects existing trees during construction?

  1. Adding a few inches of fill around the trunks to protect the roots
  2. Removing limbs that overhang the work area
  3. Fencing a tree protection zone around the critical root area before work begins Correct answer.
  4. Watering the trees daily throughout construction

Explanation

Most tree damage during construction comes from soil compaction, root severing, and grade changes within the root zone. A fenced protection zone established before any equipment arrives keeps those impacts out of the critical root area.

Question 33Environmental & Contextual Conditions

Which stormwater practice is intended primarily to infiltrate runoff close to where it is generated?

  1. A bioretention cell in a parking lot island Correct answer.
  2. A curb and gutter system
  3. A concrete-lined channel
  4. A dry detention pond at the outfall

Explanation

Bioretention cells use engineered soils and vegetation to capture and infiltrate runoff at its source, reducing both volume and pollutants before they leave the site. Conveyance and end-of-pipe facilities move water quickly rather than infiltrating it.

Question 34Environmental & Contextual Conditions

For a rectangular building in a cold climate intended to use passive solar heating, the long axis should generally run in which direction?

  1. Northwest-southeast
  2. Parallel to the prevailing winter wind
  3. East-west Correct answer.
  4. North-south

Explanation

An east-west long axis maximizes the area of south-facing wall and glass, which is the surface that collects useful solar gain in winter. It also minimizes east and west exposures that cause overheating in summer.

Question 35Environmental & Contextual Conditions

Which landscape strategy best improves summer cooling without sacrificing winter solar gain on a south facade?

  1. Planting evergreen trees along the south facade
  2. Installing a solid fence along the south property line
  3. Planting deciduous trees along the south facade Correct answer.
  4. Paving the area directly south of the building

Explanation

Deciduous trees leaf out in summer and block high-angle sun, then drop their leaves in winter so low-angle sun can reach the facade. This seasonal variation is what makes them useful for both cooling and heating.

Question 36Environmental & Contextual Conditions

Which facade typically receives the most difficult low-angle summer sun to control with a horizontal overhang alone?

  1. North
  2. All facades equally
  3. South
  4. West Correct answer.

Explanation

Low afternoon sun strikes the west facade nearly perpendicular to the glass, so a horizontal overhang blocks little of it. Vertical fins, screens, or exterior shading devices are more effective on east and west orientations.

Question 37Environmental & Contextual Conditions

To reduce highway traffic noise at a proposed residence, where should an earth berm be placed?

  1. Behind the house, opposite the highway
  2. At the property line farthest from the highway
  3. Around the house on all sides
  4. Between the highway and the house, close to the highway Correct answer.

Explanation

Noise barriers work by interrupting the line of sight between source and receiver, so placing the berm close to the source creates the largest shadow zone behind it. A barrier near the receiver is less effective because sound can diffract over it.

Question 38Environmental & Contextual Conditions

Why does the National Flood Insurance Program restrict development in a designated floodway?

  1. To prohibit all uses, including parks and agriculture
  2. To prevent construction on land that is below the water table
  3. To reserve land for future levee construction
  4. To keep the floodway open so the base flood can pass without raising flood levels Correct answer.

Explanation

The floodway is the channel and adjacent area that must remain unobstructed for the base flood to pass without increasing flood heights on other properties. Development is limited to uses that do not raise the base flood elevation by more than the allowed amount.

Question 39Environmental & Contextual Conditions

A community requires one foot of freeboard above the base flood elevation of 102.0 feet. What is the minimum permitted elevation of the lowest floor?

  1. 104.0 feet
  2. 101.0 feet
  3. 103.0 feet Correct answer.
  4. 102.0 feet

Explanation

Freeboard is added on top of the base flood elevation to provide a margin of safety against wave action, debris, and future floodplain changes. Adding one foot to 102.0 feet gives a lowest floor at 103.0 feet.

Question 40Environmental & Contextual Conditions

A site has a seasonal high water table three feet below grade, and a basement is proposed. Which approach is most appropriate?

  1. Raise the basement floor above the water table and slope grade away
  2. Install a sump pump and omit waterproofing
  3. Design the basement as a waterproofed, structurally braced box with perimeter drainage Correct answer.
  4. Ignore the groundwater and rely on a standard damp-proofing coating

Explanation

Where a basement extends below the water table, hydrostatic pressure acts on the walls and slab, so the structure must be designed to resist it. Waterproofing plus a perimeter drainage system and structural bracing manages both water and pressure.

Question 41Environmental & Contextual Conditions

On a steep hillside, which grading technique best improves slope stability for a building pad?

  1. Terracing the slope with benches and controlled drainage Correct answer.
  2. Concentrating drainage at the toe of the slope
  3. Placing fill at the top of the slope without compaction
  4. Cutting a single vertical face into the hillside

Explanation

Benching breaks a long slope into shorter, flatter segments and intercepts surface and subsurface water before it saturates the soil. Compaction, controlled drainage, and revegetation complete a stable hillside pad.

Question 42Environmental & Contextual Conditions

In a warm climate with reliable summer breezes from the southwest, how should a naturally ventilated building be oriented?

  1. With all operable windows concentrated on the north facade
  2. With its long axis roughly perpendicular to the summer breezes Correct answer.
  3. With its long axis running north-south regardless of wind
  4. With its long axis roughly parallel to the summer breezes

Explanation

A long axis perpendicular to the prevailing summer wind places the largest facade and the most windows on the windward side, capturing the breeze for cross ventilation. Windows on the leeward side allow air to exit and complete the flow path.

Question 43Environmental & Contextual Conditions

In a cold climate, the required depth of building footings is most directly governed by which condition?

  1. The depth of the seasonal high water table
  2. The elevation of the base flood
  3. The bearing capacity of the subsoil
  4. The depth of frost penetration in the soil Correct answer.

Explanation

Footings must bear below the depth to which the ground freezes so that frost heave does not lift and crack the foundation. Frost penetration depth is set by local climate and soil conditions and is published in local building codes.

Question 44Environmental & Contextual Conditions

What is the primary function of a vegetated buffer along the edge of a wetland?

  1. To increase the rate of stormwater discharge into the wetland
  2. To filter sediment and nutrients from runoff before it reaches the wetland Correct answer.
  3. To provide a construction staging area
  4. To lower the local water table

Explanation

A buffer of dense vegetation slows runoff and allows sediment and nutrients to settle out or be taken up by plants before reaching the wetland. It also moderates temperature and provides habitat edge.

Question 45Environmental & Contextual Conditions

A property is granted legal nonconforming status under a new zoning ordinance. What does this typically allow?

  1. Continuation of the existing use, subject to limits on expansion Correct answer.
  2. Any new use permitted in the new district
  3. Unlimited expansion of the existing structure
  4. Reconstruction at a larger scale after a fire

Explanation

Nonconforming status protects a use or structure that lawfully existed before the ordinance took effect, allowing it to continue. Most ordinances limit enlargement, reconstruction after major damage, and changes to more intensive uses.

Question 46Environmental & Contextual Conditions

A building will be 40 feet tall. If the sun's altitude is 30 degrees above the horizon, approximately how long is the shadow it casts on level ground?

  1. 20 feet
  2. 69 feet Correct answer.
  3. 80 feet
  4. 46 feet

Explanation

Shadow length equals the building height divided by the tangent of the solar altitude: 40 divided by tan 30 degrees, or about 69 feet. As the sun gets lower in the sky, shadows lengthen rapidly.

Question 47Environmental & Contextual Conditions

What is the approximate solar altitude at solar noon on the winter solstice at 40 degrees north latitude?

  1. 26.5 degrees Correct answer.
  2. 73.5 degrees
  3. 40 degrees
  4. 50 degrees

Explanation

Winter solstice noon altitude equals 90 degrees minus the latitude minus 23.5 degrees of axial tilt, so 90 minus 40 minus 23.5 gives about 26.5 degrees. This low sun angle is why winter shadows are long and south-facing glass receives deep solar penetration.

Question 48Environmental & Contextual Conditions

The solar envelope of a site is determined primarily by which factor?

  1. The shadow that a massing would cast at critical sun angles on adjacent properties Correct answer.
  2. The zoning district's maximum building height
  3. The orientation of the nearest street grid
  4. The average daily sunshine hours recorded on the site

Explanation

A solar envelope is a three-dimensional buildable volume derived from the shadows a building may cast at critical times, usually the winter solstice, onto neighbors' solar access. It is a performance-based limit rather than a simple height limit.

Question 49Environmental & Contextual Conditions

On a map with a 2-foot contour interval, the horizontal distance between two successive contours along a proposed road is 50 feet. What is the approximate grade of the road?

  1. 0.4 percent
  2. 4 percent Correct answer.
  3. 10 percent
  4. 2 percent

Explanation

Grade is the vertical change divided by the horizontal distance, so 2 feet over 50 feet equals 0.04, or 4 percent. Successive contours one interval apart always represent that same vertical rise, so only the horizontal spacing changes the grade.

Question 50Environmental & Contextual Conditions

A site slopes at 15 percent and a driveway must not exceed 10 percent. Which alignment is most appropriate?

  1. Running the driveway along the steepest contour
  2. Running the driveway straight up the fall line
  3. Cutting a vertical trench for the driveway
  4. Angling the driveway diagonally across the slope Correct answer.

Explanation

Angling the driveway across the slope lengthens its horizontal run for the same vertical rise, which lowers the grade below the maximum. A diagonal alignment also reduces the cut and fill needed compared with running straight uphill.
