Inventory, Analysis, and Project Management

Question 1

Refer to Section A–A. A park district wants a scenic overlook with an unobstructed view of the whole lake surface, measured from ground level. The overlook must be outside the 100-year floodplain (elevation 28). Select the location.

Click the correct area of the figure.

Show answer & explanation

Answer: C

  1. Point 2 to the near shore: from (station 190, elev. 80) to (station 510, elev. 20), the line drops 60 over 320 units.
  2. At the ridge (station 370): 80 − 60 × 180 ÷ 320 = 46.3 < 70, so the view is blocked.
  3. Point 3 to the shore: from (370, 70) to (510, 20), the line is at 45 at station 440 (ground 40) and 27.1 at station 490 (ground 24), so it is clear.
  4. Point 4 (elev. 24) is below the 28 flood elevation.

Circle at Point 1: At elevation 50, the view east is blocked by the 80 hilltop and the 70 ridge.

Circle at Point 2: It is the highest point, but the sight line to the lake shore falls to about 46 at the ridge (station 370), which is below the ridge top at 70, so the ridge hides the lake.

Circle at Point 3: Correct. From the 70 ridge the ground falls in a concave slope to the shore, so the sight line clears the terrain to the whole lake, and the point is well above flood elevation 28.

Circle at Point 4: It sees the lake, but at elevation 24 it lies below flood elevation 28, inside the floodplain, which breaks the stated constraint.

In a visual resource analysis, check sight lines on a section: an intervening high point blocks the view whenever the straight line from viewer to target passes below it. The site must also meet every non-visual constraint.

Question 2

Refer to the plan. During a slope analysis for a proposed trail, the landscape architect checks the existing grade between Point A and Point B. What is the average slope between the two points?

Existing contours (elevations in units)

Existing contours are dashed and labelled in units. Figure not drawn to scale.
Show answer & explanation

Answer: C

  1. Givens: Point A is on the 104 contour, Point B on the 96 contour; horizontal distance 40 units.
  2. Rise = 104 − 96 = 8 units (four 2-unit intervals).
  3. Slope % = rise ÷ run × 100.
  4. Slope = 8 ÷ 40 × 100 = 20%.

5%: Uses only one 2-unit contour interval as the rise (2 ÷ 40 × 100); A and B are four intervals apart.

10%: Treats each of the four intervals as 1 unit (4 ÷ 40 × 100); the labels show a 2-unit interval.

20%: Correct. The rise is 104 − 96 = 8 units over a 40-unit run: 8 ÷ 40 × 100 = 20%.

25%: Counts five contour lines × 2 units = 10 units of rise; five lines bound only four intervals, so the rise is 8.

Slope % = rise ÷ horizontal run × 100; take the rise from the contour labels (number of intervals × interval), not from the number of contour lines.

Question 3

A school district plans a quiet outdoor learning garden for the adjacent elementary school. The adopted thoroughfare plan programs the two-lane county road on the east for widening to a six-lane arterial. The garden must be outside the floodplain and as far as possible from future traffic noise. Select the location.

Click the correct area of the figure.

NLocal street (two lanes)County road(future 6-lane)CreekElementaryschoolFloodplain(1% annualchance)PROPERTY LINE (dashed)
Figure not drawn to scale.
Show answer & explanation

Answer: A

North-west zone: Correct. It is outside the floodplain, next to the school, and farthest from the future six-lane arterial.

North-east zone: Quiet today, but it borders the county road that will become a six-lane arterial.

South-west zone: Near the school, but it lies within the 1-percent-annual-chance floodplain.

South-east zone: Within the floodplain and next to the future arterial, so it fails both criteria.

Contextual analysis looks beyond current conditions: adopted plans for future roads and development change which locations remain suitable.

Question 4

A county is siting a restroom building in a riverside park. County policy requires the building to be outside both the 1-percent-annual-chance and the 0.2-percent-annual-chance flood hazard areas shown on the flood map. Which location meets the policy?

Figure not drawn to scale.
Show answer & explanation

Answer: D

Location A: Lies in the regulatory floodway, which is the most hazardous part of Zone AE.

Location B: Lies in Zone AE, the 1-percent-annual-chance flood hazard area.

Location C: Lies in shaded Zone X, the 0.2-percent-annual-chance flood hazard area.

Location D: Correct. It lies in unshaded Zone X (minimal flood hazard), outside both mapped flood hazard areas.

On a flood map, Zone AE (with its floodway) is the 1-percent-annual-chance hazard area and shaded Zone X is the 0.2-percent-annual-chance area; only unshaded Zone X is outside both.

Planning and Design

Question 5

Refer to the exhibit. The site for a community arts center's grounds is divided into four zones. Using the program and the functional relationship diagram, place each use in its zone; uses not in the program are not placed. Place the elements in their corresponding locations.

Exhibit

Community arts center grounds program: • Entry plaza: must front Main Street. • Café terrace: directly next to the entry plaza; receives deliveries from the service yard. • Service yard: must have direct access from the service alley. • Quiet garden: next to the residences and kept away from Main Street. Each zone holds exactly one use.

Turn a functional relationship diagram into a site layout by placing the most constrained uses first (street frontage, service access), then fitting the uses that must touch them. CLARB scores the placement all-or-nothing.

Question 6

A park path will connect point X (elevation 100.0) to an overlook at point Y (elevation 110.0). The path must be an accessible route with a running slope no steeper than 5%, so that it is not a ramp, and it must not cross the stream. Each alignment climbs at a uniform grade. Select the plan.

Existing contours dashed, interval 2 units. Each path climbs at a uniform grade. Figure not drawn to scale.
Show answer & explanation

Answer: B

  1. Rise = 110.0 − 100.0 = 10.0 units for every plan.
  2. Slope % = rise ÷ length × 100.
  3. Plan A: 10 ÷ 120 × 100 = 8.3% (fails, over 5%).
  4. Plan B: 10 ÷ 230 × 100 = 4.3% (passes; no stream crossing).
  5. Plan C: 10 ÷ 260 × 100 = 3.8% (slope passes, but it crosses the stream).

Plan A: Plan A: 10 ÷ 120 × 100 = 8.3%. Steeper than 5%, so it would have to be designed as a ramp.

Plan B: Correct. Plan B: 10 ÷ 230 × 100 = 4.3%, within the 5% maximum, and the switchbacks stay west of the stream.

Plan C: Plan C: 10 ÷ 260 × 100 = 3.8% meets the slope limit, but the loop crosses the stream twice, which the criteria prohibit.

An accessible route steeper than 1:20 (5%) becomes a ramp; lengthening the alignment with switchbacks lowers the grade, but every other stated constraint still applies.

Question 7

Refer to the exhibit. A weighted suitability overlay is being used to locate an athletic complex in a park master plan. Each candidate area is scored for three factors, and each score is multiplied by its factor's weight. Which area is MOST suitable?

Exhibit

Athletic complex suitability (score 1 = poor, 3 = good)
AreaSlope (weight 3)Soil drainage (weight 2)Road access (weight 1)
A321
B223
C133
D231
Weighted score = sum of (score × weight).
Show answer & explanation

Answer: A

  1. Weights: slope 3, soil drainage 2, road access 1.
  2. A = 3(3) + 2(2) + 1(1) = 9 + 4 + 1 = 14.
  3. B = 2(3) + 2(2) + 3(1) = 6 + 4 + 3 = 13.
  4. C = 1(3) + 3(2) + 3(1) = 3 + 6 + 3 = 12.
  5. D = 2(3) + 3(2) + 1(1) = 6 + 6 + 1 = 13.
  6. Highest weighted total: Area A (14). (Unweighted sums would favor B and C at 7, which is why weights matter.)

Area A: Correct. Weighted totals: A = 3×3 + 2×2 + 1×1 = 14; B = 13; C = 12; D = 13. Area A scores highest because it is best on slope, the most heavily weighted factor.

Area B: B totals 6 + 4 + 3 = 13. It ties for the highest unweighted sum (7), which is the error of ignoring the weights.

Area C: C totals 3 + 6 + 3 = 12, the lowest. Its strong soil and access scores cannot offset the poorest slope, which carries the most weight.

Area D: D totals 6 + 6 + 1 = 13, one point below Area A.

A weighted overlay multiplies each factor score by its weight before summing, so the factor the program cares most about (here slope for playing fields) drives the result.

Construction Documentation and Administration

Question 8

Refer to the exhibit. The contractor has submitted product data for the concrete pavers on a plaza that carries service vehicles. What action should the landscape architect take?

Exhibit

Concrete pavers: thickness 3 1/8 in [80 mm]; minimum average compressive strength 8,000 psi [55 MPa]; maximum average absorption 5%; color to match the approved sample.

Show answer & explanation

Answer: B

Approve it, because strength and absorption exceed the requirements: Better strength and absorption do not offset the thickness shortfall; the paver still fails a stated requirement for a vehicular surface.

Return it marked revise and resubmit for the noncompliant thickness: Correct. The submitted paver is 60 mm thick where 80 mm is specified, so the submittal does not conform and must be corrected and resubmitted.

Approve it with a note that the pavers be installed 80 mm thick: A review note cannot change the thickness of a manufactured product; approving it would accept nonconforming material.

Forward it to the owner to decide whether thinner pavers are acceptable: Submittal review is the landscape architect's role; a deliberate deviation would need a substitution request or change, not owner review of a noncompliant submittal.

A submittal is reviewed against every specified requirement; if any required property is not met, it is returned for revision, however well it meets the others.

Question 9

During construction of a riverfront trail, the owner wants 200 linear feet [61 m] of boardwalk railing added so that a section can open for a festival in three weeks. The owner and the contractor have not agreed on the price of the added work. Which instrument BEST allows the work to proceed now?

Show answer & explanation

Answer: D

An addendum to the contract documents: Addenda modify the bidding documents before bid opening; this contract has already been awarded.

A change order signed by the owner and contractor: A change order records agreement on the change in price and time; that agreement does not exist yet, so a change order cannot be executed now.

A request for information from the contractor: An RFI asks for clarification of the documents; it does not authorize added work or adjust the contract.

A construction change directive: Correct. A construction change directive, issued by the owner through the landscape architect, directs the contractor to proceed with changed work before price and time are agreed; the adjustment is settled later and recorded by change order.

Use a change order when owner and contractor agree on price and time; use a construction change directive when the owner needs the change to proceed before that agreement.

Question 10

Two accessible parking spaces with a shared access aisle must be added to the parking lot shown. The main entrance has stairs; the east door is the building's accessible entrance. Select the location.

Click the correct area of the figure.

Site plan — parking and entrances
BuildingWalkMain entrance (stairs)Accessible entranceDriveaisleStreetN
Each candidate area holds two spaces with a shared access aisle. Not to scale.
Show answer & explanation

Answer: B

West row, south end: Closest to the stepped main entrance, which is not accessible; the route to the accessible door is longer.

West row, north end: Correct. The access aisle opens straight onto the walk beside the accessible entrance: the shortest accessible route, with no drive aisle to cross.

East row, north end: Opposite the entrance, but the route crosses the vehicular drive aisle.

East row, south end: Farthest from the accessible entrance, and the route crosses the drive aisle.

Accessible parking goes on the shortest accessible route to an accessible entrance, with the access aisle adjoining that route and, where possible, no crossing of vehicular traffic.

Question 11

Refer to the exhibit. Boardwalk joists will span 12'-0" [3.66 m] between beams and be spaced 16 in [400 mm] on center. What is the smallest joist size that meets the span?

PrepBanq simplified wood span table (practice values only; not CLARB's chart and not for design). A joist may cantilever past its beam up to 1/4 of its backspan (the span between ledger and beam).
Show answer & explanation

Answer: C

  1. Given: clear span 12'-0", joists at 16 in [400 mm] o.c.
  2. Use only the 16 in o.c. column of Table 1.
  3. Read down: 2x6 = 8'-6" (too short); 2x8 = 11'-0" (too short); 2x10 = 14'-0" (OK).
  4. Smallest member whose maximum span ≥ 12'-0": 2x10.

2x6 [50x150]: At 16 in o.c. a 2x6 spans only 8'-6", well short of 12'-0".

2x8 [50x200]: At 16 in o.c. a 2x8 spans 11'-0", which is short of 12'-0". The 12'-6" value belongs to the 12 in o.c. column.

2x10 [50x250]: Correct. In the 16 in o.c. column a 2x10 spans 14'-0", the first value that equals or exceeds 12'-0".

2x12 [50x300]: A 2x12 (16'-6") works but is larger than needed; the question asks for the smallest member.

For a span table, pick the spacing column first, then move down to the first member whose maximum span equals or exceeds the required span.

Grading, Drainage, and Stormwater Management

Question 12
Storm drain profile

Figure not drawn to scale.

Refer to the storm drain profile. The invert elevations step down 0.10 across MH-1. Place the appropriate invert elevations in the boxes provided. Box 1 (MH-1 invert in): . Box 2 (MH-1 invert out): . Box 3 (outfall invert): .

Show answer & explanation

Answer: (1) 94.00, (2) 93.90, (3) 92.70

  1. Fall = slope × length.
  2. Pipe 1 fall = 0.010 × 120 = 1.20; MH-1 invert in = 95.20 − 1.20 = 94.00.
  3. MH-1 invert out = 94.00 − 0.10 = 93.90.
  4. Pipe 2 fall = 0.015 × 80 = 1.20; outfall invert = 93.90 − 1.20 = 92.70.

Downstream invert = upstream invert − (slope × length); the outlet invert of a structure is set below its inlet invert by the stated drop.

Question 13

A landscape architect is reviewing four alternative proposed contour layouts for a lawn swale. The swale must collect runoff and carry it south to the inlet shown at the bottom of each plan. Select the plan.

Click the correct area of the figure.

Proposed contours, 1-unit interval. North is at the top of each plan.
Show answer & explanation

Answer: B

Upper-left plan: The V's point toward higher contours, so it is a swale, but elevations rise toward the inlet; it drains north, away from the inlet.

Upper-right plan: Correct. The V's point uphill (north, toward the higher numbers), forming a swale, and elevations fall to 100 at the inlet.

Lower-left plan: The V's point downhill toward lower numbers, which forms a ridge that sheds water away from the centerline and the inlet.

Lower-right plan: The 101 contour crosses the 100 contour; contours of different elevations can never cross or touch except at a vertical face.

Contour V's that point uphill (toward higher numbers) mark a swale; V's pointing downhill mark a ridge. Check the numbering to confirm the flow direction.

Question 14

Refer to the exhibit. A storm sewer inlet is being sized for the drainage area described. Using the Rational Method (q = CiA), what is the peak runoff to the inlet?

Exhibit

Rainfall intensity, i (in/hr), by storm duration and return period
Duration (min)2-year10-year25-year
55.47.08.2
104.45.86.8
153.85.06.0
302.63.64.3
601.72.42.9
Use the duration equal to the time of concentration.
Show answer & explanation

Answer: C

  1. Givens: C = 0.60, A = 5.0 ac, Tc = 15 min, 10-year storm.
  2. Read i where duration = Tc = 15 min in the 10-year column: i = 5.0 in/hr.
  3. q = CiA = 0.60 × 5.0 in/hr × 5.0 ac.
  4. q = 15.0 cfs.

7.2 cfs: Uses the 60-minute intensity (2.4 in/hr); the storm duration must equal the 15-minute time of concentration.

11.4 cfs: Uses the 2-year column (3.8 in/hr); the design storm is the 10-year event.

15.0 cfs: Correct. i for a 15-minute, 10-year storm is 5.0 in/hr; q = 0.60 × 5.0 × 5.0 = 15.0 cfs.

18.0 cfs: Uses the 25-year column (6.0 in/hr), which over-designs the inlet for the stated 10-year storm.

In the Rational Method, read the intensity for the design return period at a duration equal to the time of concentration, then multiply by C and A (acres) to get cfs.
