Sample NV C-10 Landscape Contracting Practice Questions

Try these sample questions to test your NV C-10 Landscape Contracting exam readiness. Each question includes a detailed explanation. Start the interactive quiz above for the full 100+ question experience with AI tutoring.

1Under NAC 624.280, which work is inside the Nevada C-10 landscape contracting classification?
A.Grading plots for architectural horticulture and installing landscape irrigation
B.Installing a 120-volt patio receptacle circuit
C.Building a load-bearing concrete driveway approach
D.Constructing an engineered swimming pool
Explanation: NAC 624.280 lets a C-10 contractor grade and prepare plots for architectural horticulture, plant and maintain vegetation, and construct drainage and landscape irrigation. Line-voltage wiring, load-bearing paving, and engineered pools are other classifications. Stay inside the horticulture, irrigation, and limited hardscape scope on the trade exam.
2Before excavating planting pits, irrigation trenches, or a French drain, what must the C-10 crew do first?
A.Call 811 and wait for utility marks
B.Order all plants so they can go in the same day as digging
C.Soak the site overnight so the soil is easier to shovel
D.Cut all existing tree roots that are in the way
Explanation: Nevada law and standard pre-construction practice require a call to 811 so buried gas, electric, communications, and water lines are marked before the shovel or trencher starts. Landscape work is shallow compared with building footings, but irrigation mains and drain trenches still hit laterals. Do not start digging on an unmarked site.
3What is the first design task on a new residential landscape after the contract and utility locate are in place?
A.Perform a site analysis of sun, wind, slope, soil, drainage, and existing vegetation
B.Order every plant on the wish list at mature size
C.Set all irrigation heads before the planting plan exists
D.Import 12 inches of potting mix over the entire lot
Explanation: A landscape plan starts with site analysis. Exposure, prevailing wind, existing grades, soil, drainage paths, and plants that will stay drive hydrozones, plant selection, and finish grade. Skipping that step is how Mojave yards get shade plants in west exposures and water directed at the foundation.
4Why should a C-10 planting plan group plants into hydrozones?
A.So plants with similar water need, sun, and soil can be irrigated together
B.So every plant on the lot can share one spray zone
C.So the contractor can skip a backflow preventer
D.So turf and cactus can be mixed on the same rotary zone
Explanation: Hydrozoning puts high-, moderate-, and low-water plants on separate valves so run time matches need. In Southern Nevada that usually means turf or a small oasis zone, a drip shrub zone, and a very-low desert zone. Mixing a lawn spray with desert shrubs on one clock wastes water and kills the dry-side plants.
5A complete C-10 construction set for a custom yard should include which drawing set?
A.A scaled layout with planting schedule, irrigation plan, and finish-grade or drainage notes
B.Only a plant photo collage with no dimensions
C.A business-license photocopy taped to the permit board
D.A freehand sketch with no north arrow or scale
Explanation: The crew needs a scaled plan showing plant locations and a schedule (botanical name, size, quantity), irrigation mains, valves, and heads or drip, plus how finish grade will drain. Without scale and notes, quantities, pipe sizes, and slope cannot be checked. Photo boards and unscaled sketches are sales tools, not construction documents.
6Which proposed structure is outside C-10 scope even if it is in a planted yard?
A.A site-built engineered trellis designed as a load-bearing shade structure
B.A nonengineered prefabricated arbor from the manufacturer’s kit
C.A decorative dry creek of cobble and sand using xeriscape materials
D.A hydroseeded slope with tackifier and mulch
Explanation: NAC 624.280 allows nonengineered prefabricated trellises and arbors installed with the landscape. A site-built engineered, load-bearing shade structure is carpentry or general building, not C-10. Decorative xeriscape materials and hydroseeding are expressly in the classification.
7On a Las Vegas lot, which microclimate usually needs the most heat- and drought-tolerant plant palette?
A.A west-facing wall that reflects late-day sun onto the planting bed
B.A north courtyard shaded by the house all afternoon
C.A covered patio with only morning light
D.The north side of a two-story house
Explanation: West exposures in the Mojave get the hottest reflected radiation and the longest late-day bake. Plants that look fine on a north or east bed will scorch there. Design the west strip with desert-adapted species, extra mulch, and drip — not the same list used in a shaded courtyard.
8Finish grade next to a house slab should do which of the following?
A.Fall away from the foundation, commonly about 6 inches in the first 10 feet where the lot allows
B.Slope toward the foundation so planting basins stay full
C.Be perfectly flat so irrigation water ponds evenly against the stem wall
D.Be built up against siding to hide the stem wall
Explanation: Surface water must leave the foundation. The International Residential Code drainage target used in residential work is at least 6 inches of fall in the first 10 feet, or a drain when that slope cannot be made. Planting basins belong out in the yard, not as a moat against the house. Backfill against siding traps moisture.
9A homeowner wants one C-10 bid for all of the following. Which single item forces another classification or an engineer?
A.Drip conversion of existing shrub beds
B.A 3-foot landscape retaining wall with gravel backfill
C.A 24-volt path-light circuit on a listed transformer
D.A 5-foot site-built masonry wall that will hold a driveway surcharge
Explanation: C-10 walls stop at 3 feet and are landscape walls, not structural walls that retain a driveway load. A 5-foot wall with surcharge is engineered masonry or another classification. Drip conversion, a 3-foot landscape wall, and 24-volt lighting are inside C-10 when built to the trade rules.
10What does “grade and prepare plots for architectural horticulture” mean on a C-10 job?
A.Shape planting areas, set finish grades, and prepare soil for designed plantings
B.Rough-cut a county road alignment to subgrade
C.Install underground electrical primary
D.Pour structural footings for a new house
Explanation: Architectural horticulture is designed planting — gardens, lawns, shrubs, and trees — not highway or building earthwork. C-10 grading shapes beds, swales, and planting pads so plants and irrigation work. Road subgrade and structural footings belong to excavating or general building classifications.
