Question 1Section 1

A site plan shows a proposed retaining wall crossing a property line by 0.4 feet. Which professional responsibility does the landscape architect have before issuing the construction documents?

  1. Note the conflict only in the general conditions of the specification
  2. Ask the contractor to resolve the conflict during construction layout
  3. Verify the boundary survey and adjust the design to respect the recorded property line Correct answer.
  4. Proceed because minor encroachments are permitted within standard survey tolerance

Explanation

Landscape architects are responsible for designing within legally established property boundaries, which requires confirming the boundary survey and resolving encroachments before bidding and construction. Encroachments create liability and may require easements or redesign. Delegating resolution to the contractor shifts a design responsibility improperly.

Question 2Section 1

Which drawing type most directly communicates the vertical relationship between proposed grades and existing topography across an entire site?

  1. Grading plan Correct answer.
  2. Irrigation plan
  3. Lighting plan
  4. Planting plan

Explanation

A grading plan depicts existing and proposed contours, spot elevations, and drainage patterns, showing how proposed surfaces relate to existing terrain. Planting, irrigation, and lighting plans address other systems and do not convey overall vertical site relationships.

Question 3Section 1

During a pre-design site visit, a landscape architect observes a stand of mature oaks on the north edge of the parcel. Which action best supports later tree protection planning?

  1. Record the trees' location, species, size, and apparent health on a base survey Correct answer.
  2. Recommend removal to simplify the layout
  3. Photograph the trees without locating them on the survey
  4. Estimate the total canopy area to calculate a planting budget

Explanation

Accurate inventory data-location, species, caliper or diameter, and condition-forms the basis for tree protection zones, preservation decisions, and layout adjustments. Canopy area alone cannot support protection distances, and unlocated photographs are insufficient for design.

Question 4Section 1

In the United States, which regulation most directly governs the discharge of stormwater from a construction site disturbing more than one acre?

  1. The Safe Drinking Water Act
  2. The Endangered Species Act
  3. The Clean Water Act's NPDES construction general permit program Correct answer.
  4. The National Historic Preservation Act

Explanation

The Clean Water Act regulates point-source discharges through NPDES permits, and construction sites disturbing one acre or more require coverage under a construction general permit with a stormwater pollution prevention plan. The other statutes address historic resources, species protection, and drinking water quality rather than construction stormwater discharge.

Question 5Section 1

A client asks whether a proposed pavilion meets the local zoning setback from the rear property line. Which document provides the authoritative basis for that answer?

  1. The manufacturer's product data for the pavilion
  2. The project's planting schedule
  3. The contractor's means-and-methods plan
  4. The adopted zoning ordinance and the approved site survey Correct answer.

Explanation

Setback requirements are established in the adopted zoning ordinance, and compliance is measured against the surveyed property line. Means-and-methods plans, product data, and planting schedules do not establish legal dimensional requirements.

Question 6Section 1

Which soil characteristic is most important to confirm when designing an infiltration basin?

  1. Saturated hydraulic conductivity of the underlying soil Correct answer.
  2. Slope of adjacent roofs
  3. Color of the surface topsoil
  4. Depth of the seasonal mulch layer

Explanation

Infiltration rate, commonly expressed as saturated hydraulic conductivity, determines whether and how quickly stormwater will infiltrate and is fundamental to sizing and feasibility. Topsoil color, roof slope, and mulch depth do not govern infiltration performance.

Question 7Section 1

Which scale is most appropriate for a construction detail showing a wall footing and drainage aggregate?

  1. 1 inch equals 500 feet
  2. 1 inch equals 1 foot Correct answer.
  3. 1 inch equals 100 feet
  4. 1 inch equals 1 mile

Explanation

Construction details require large scales, commonly 1 inch equals 1 foot or larger, to show materials, dimensions, and assembly clearly. Small scales such as 1:100, 1:500, or 1:1 mile are suited to site or regional plans, not detail construction.

Question 8Section 1

Which survey element is essential before calculating the volume of cut and fill for a proposed parking terrace?

  1. Existing and proposed spot elevations or contours Correct answer.
  2. Utility company contact list
  3. Property owner names
  4. Zoning hearing dates

Explanation

Earthwork volumes are computed by comparing existing and proposed surfaces, typically using contours or spot elevations and a grid or digital terrain model. Owner names, utility contacts, and hearing dates do not provide the vertical data needed for volume calculation.

Question 9Section 1

A landscape architect is preparing a planting plan for a site where the client wants a low-maintenance native palette. Which selection criterion most directly supports that goal?

  1. Species selected primarily for exotic flower color
  2. Species with the largest mature canopy size
  3. Species requiring frequent supplemental irrigation
  4. Species adapted to the site's soil, moisture, and climate conditions Correct answer.

Explanation

Matching species to existing soil, moisture, and climate reduces establishment and long-term maintenance inputs, which is the core of a low-maintenance native approach. Large canopy size, high water demand, or novelty flower color do not inherently reduce maintenance.

Question 10Section 1

A proposed walkway must be accessible. Which condition must be verified for a ramp connecting two levels?

  1. Only the ramp's total length
  2. Only the ramp's surface color
  3. Only the number of pedestrians expected
  4. Slope, landings, handrails, and edge protection meeting accessibility standards Correct answer.

Explanation

Accessible routes require compliance with slope limits, landing dimensions and spacing, handrails where required, and edge protection, not a single isolated measurement. Length alone, surface color, and pedestrian counts do not establish accessibility compliance.

Question 11Section 1

A client requests a plaza that will be irrigated with harvested roof runoff. Which analysis best determines whether the storage volume is adequate?

  1. A lighting calculation for the plaza
  2. A wind rose analysis for the site
  3. A soil texture classification of the plaza subbase
  4. A water balance comparing catchment yield, storage capacity, and seasonal demand Correct answer.

Explanation

A water balance compares the runoff volume captured from the roof against storage capacity and the seasonal irrigation demand to determine whether supply meets need. Soil texture, wind roses, and lighting calculations do not quantify harvested water supply and demand.

Question 12Section 1

A landscape architect is preparing a cost opinion during schematic design. Which method is most appropriate at this stage?

  1. Negotiated lump-sum contract pricing
  2. Competitive bidding from qualified contractors
  3. Detailed quantity takeoff from final construction documents
  4. Unit-cost estimating based on typical quantities per area Correct answer.

Explanation

Schematic design estimates rely on unit costs applied to approximate quantities or areas because detailed quantities are not yet developed. Bidding, detailed takeoffs, and negotiated lump-sum pricing require completed documents and occur later.

Question 13Section 1

Which practice best protects a mature tree's critical root zone during construction?

  1. Placing the fence at the trunk and allowing grading to the drip line
  2. Fencing the critical root zone and prohibiting grade changes and storage within it Correct answer.
  3. Lowering the grade within the drip line to improve drainage
  4. Stockpiling topsoil within the drip line

Explanation

Tree protection relies on fencing the critical root zone before demolition or grading and preventing grade changes, compaction, and material storage within it. Fencing only at the trunk, stockpiling soil, or lowering grade within the root zone causes root loss and compaction damage.

Question 14Section 1

A site plan shows a proposed building corner set at 8 feet from the side lot line where the zoning requires a 10-foot side setback. What is the most appropriate design response?

  1. Obtain a contractor's written waiver of the setback
  2. Reduce the setback requirement in the project specifications
  3. Proceed because the corner is a minor architectural feature
  4. Shift or resize the building footprint to achieve the required setback Correct answer.

Explanation

Zoning setbacks are legal requirements enforced through permits, and noncompliance requires redesign or a formal variance from the local authority. Contractors cannot waive zoning, specifications cannot override an ordinance, and no de minimis exception applies to a 2-foot deficiency.

Question 15Section 1

During construction observation, a landscape architect notices the contractor installing pavers on a base that appears thinner than specified. What is the appropriate first action?

  1. Ignore the condition because observation is not inspection
  2. Direct the contractor's crew to remove and replace the base
  3. Document the observed condition and notify the contractor and owner in writing Correct answer.
  4. Approve the work because the base is hidden after installation

Explanation

The landscape architect documents observed nonconforming work and notifies the contractor and owner in writing so the contractor can correct it. The landscape architect typically does not direct the contractor's workforce, and observed deviations should not be approved or ignored.

Question 16Section 1

Which erosion and sediment control measure is best suited to intercept sheet flow at the downslope perimeter of a disturbed area before it leaves the site?

  1. A riprap apron at the outlet
  2. A silt fence installed along the contour Correct answer.
  3. A check dam within the swale
  4. A sediment trap at the storm inlet

Explanation

A silt fence placed along the contour intercepts sheet flow and allows sediment to settle before runoff leaves the disturbed area. Check dams treat concentrated channel flow, inlet traps capture sediment at the inlet, and outlet aprons address velocity and scour, not perimeter sheet flow.

Question 17Section 1

A landscape architect must specify a paving material for a pedestrian plaza over a structure. Which property is most critical to verify?

  1. Manufacturer's warranty length
  2. Slip resistance under dry conditions only
  3. Unit weight of the saturated paving assembly Correct answer.
  4. Color fastness under ultraviolet light

Explanation

Paving over a structural deck is governed by dead-load limits, so the saturated unit weight of the full assembly must be checked against structural capacity. Color fastness, dry-only slip resistance, and warranty length are secondary considerations and do not determine structural feasibility.

Question 18Section 1

Which combination of factors most directly determines the required size of a stormwater detention basin?

  1. Peak inflow, allowable release rate, and required storage volume Correct answer.
  2. Soil color, mulch depth, and plant spacing
  3. Canopy coverage, wind speed, and solar exposure
  4. Fixture count, pipe diameter, and water pressure

Explanation

Detention sizing depends on routing the peak inflow through storage while limiting discharge to the allowable release rate, which together define required volume. The other options describe planting, plumbing, or microclimate factors unrelated to detention routing.

Question 19Section 1

A landscape architect is asked to preserve a mature specimen tree while raising grade by 2 feet around it. Which approach is most technically sound?

  1. Remove the tree because any grade change is fatal
  2. Place fill directly against the trunk and taper it outward
  3. Use a tree island with a retaining wall and an unaltered root zone Correct answer.
  4. Install drain tile and place fill over the entire root zone

Explanation

Retaining the existing grade within a tree island protects roots from fill-induced suffocation and moisture loss while accommodating the new grade outside the root zone. Direct fill against the trunk damages tissue, removal is not automatically required, and drain tile does not offset the harm of burying roots.

Question 20Section 1

A client wants a playground surface that reduces injury severity from falls. Which specification approach is most appropriate?

  1. Specify surfacing depth by the contractor's judgment
  2. Specify surfacing based on color matching the site furnishings
  3. Specify surfacing tested to the applicable standard for the critical fall height of the equipment Correct answer.
  4. Specify the least expensive loose aggregate available

Explanation

Impact-attenuating playground surfacing must be matched to the equipment's critical fall height and tested to the recognized safety standard. Cost alone, color, or contractor judgment does not demonstrate the required injury protection.

Question 21Section 1

A proposed green roof must manage a design storm. Which analysis best evaluates its runoff reduction performance?

  1. A wind tunnel study of the roof edge
  2. A continuous hydrologic simulation comparing pre- and post-development runoff volumes Correct answer.
  3. A single-point soil infiltration test in the plaza
  4. A glare analysis of adjacent glazing

Explanation

Green roof hydrologic performance is evaluated with continuous simulation that accounts for rainfall patterns, evapotranspiration, soil storage, and drainage to compare runoff volumes before and after development. Infiltration tests, wind studies, and glare analysis do not quantify roof runoff reduction.

Question 22Section 1

A site contains a mapped wetland. Which sequence best reflects the regulatory process before construction can affect the wetland?

  1. Assume the wetland is isolated and proceed without review
  2. Begin construction and apply for permits concurrently
  3. Rely on the site plan's generic note about wetlands
  4. Delineate and verify boundaries, then obtain the required federal and state permits with mitigation Correct answer.

Explanation

Jurisdictional wetlands must be delineated using approved methods, verified by the regulatory agency, and permitted before impacts occur, with avoidance, minimization, and compensatory mitigation evaluated in sequence. Concurrent construction, generic notes, or assumptions about isolation do not satisfy the permit requirement.

Question 23Section 1

A retaining wall 6 feet tall is proposed near a slope. Which condition most directly governs whether a geotechnical engineer's design is required?

  1. Wall height, surcharge, and slope conditions relative to code thresholds Correct answer.
  2. The number of pedestrians passing the wall
  3. The wall's finish color
  4. The planting design adjacent to the wall

Explanation

Retaining wall design requirements are triggered by height, retained soil, surcharge, and slope conditions compared with building code thresholds, which determine whether engineered design and permits are needed. Finish color, pedestrian counts, and planting do not establish structural design requirements.

Question 24Section 1

A landscape architect is comparing two irrigation strategies for a large turf area: conventional spray versus drip. Which metric best expresses the comparison of applied water to beneficial use?

  1. Distribution uniformity combined with scheduling efficiency Correct answer.
  2. Manufacturer's warranty period
  3. Pipe color coding
  4. Number of valve boxes per zone

Explanation

Water use efficiency depends on how uniformly water is applied and how well the schedule matches plant demand, so distribution uniformity combined with scheduling efficiency best expresses beneficial use. Warranty terms, valve box counts, and pipe color do not measure water efficiency.

Question 25Section 1

A project must demonstrate compliance with a local ordinance requiring on-site stormwater retention for the 95th-percentile rainfall event. Which approach best supports the design?

  1. Analyze long-term rainfall records to size storage for the specified percentile event Correct answer.
  2. Size storage using average annual rainfall depth
  3. Size storage using the site's impervious area alone
  4. Size storage for the single largest recorded storm

Explanation

Percentile-based retention standards are evaluated using long-term rainfall records to determine the event depth and frequency that the storage must manage. The largest recorded storm, average annual depth, or impervious area alone do not represent the specified percentile event.

Question 26Section 1

A landscape architect is assembling the base sheet for a schematic design set. Which drawing type establishes existing site conditions such as contours, utilities, and property lines?

  1. Grading and drainage plan
  2. Planting plan
  3. Construction details sheet
  4. Topographic survey base map Correct answer.

Explanation

The survey base map records measured existing conditions-contours, easements, property lines, and utilities-and is the reference layer on which all design drawings are built. Design drawings such as planting and grading plans depict proposed work and depend on the base map for accuracy.

Question 27Section 1

A landscape architect is calculating the area of an irregular planting bed drawn on a plan. Which method is most appropriate for estimating its area from the scaled drawing?

  1. Scaling the longest dimension only
  2. Measuring the perimeter and dividing by four
  3. Averaging the two longest sides
  4. Counting grid squares over the scaled shape Correct answer.

Explanation

Overlaying a scaled grid and counting squares (or partial squares) is a standard way to estimate the area of an irregular closed shape on a drawing. Perimeter and single dimensions describe length, not area, and cannot substitute for a two-dimensional measure.

Question 28Section 1

In a set of construction documents, which sheet is the correct location for a specification of the soil amendment mix to be tilled into planting beds?

  1. Planting plan notes or specifications Correct answer.
  2. Title sheet
  3. Civil utility plan
  4. Structural foundation plan

Explanation

Planting soil preparation is a landscape construction requirement and belongs in the planting plan notes or the written specifications that govern planting work. The other sheets address project identification, utilities, or structural work and would not carry horticultural soil requirements.

Question 29Section 1

A landscape architect is reading a grading plan and sees spot elevations of 102.5 and 100.0 at two points 25 feet apart. What is the approximate slope between them, expressed as a percentage?

  1. 1 percent
  2. 2.5 percent
  3. 10 percent Correct answer.
  4. 25 percent

Explanation

Slope percentage equals rise divided by run times 100. The rise is 2.5 feet over a 25-foot run, giving 0.10, or 10 percent. This is a routine check when verifying that a proposed surface meets drainage or accessibility limits.

Question 30Section 1

Which document establishes the legally binding obligations, schedule, and payment terms between the owner and the contractor?

  1. The construction contract agreement Correct answer.
  2. The contractor's bid form
  3. The general conditions alone
  4. The technical specifications

Explanation

The contract agreement is the executed document that binds owner and contractor to scope, schedule, and payment terms, incorporating the other documents by reference. General conditions, specifications, and bids support the agreement but do not by themselves create the binding relationship.

Question 31Section 1

A landscape architect must show the precise location of a proposed tree relative to a property line. Which reference is most reliable for that dimension on the drawing?

  1. Estimating from a neighboring tree
  2. Referencing the sheet grid only
  3. Scaling the distance from the printed sheet
  4. Dimensioning from the surveyed property line Correct answer.

Explanation

Dimensions tied to a surveyed property line give an authoritative, measurable location independent of reproduction scale. Scaling a printout or estimating introduces error and cannot be enforced in the field.

Question 32Section 1

Which term describes the line on a plan that separates areas draining to different outfalls?

  1. Benchmark
  2. Drainage divide Correct answer.
  3. Contour interval
  4. Easement

Explanation

A drainage divide is the ridge or boundary separating watersheds or subareas that flow to different discharge points. Identifying divides is fundamental to laying out stormwater management areas.

Question 33Section 1

A landscape architect needs to communicate the sequence of construction activities and their durations to the contractor. Which tool is intended for that purpose?

  1. A grading section
  2. A planting legend
  3. A bar chart construction schedule Correct answer.
  4. A materials sample board

Explanation

A bar chart schedule graphically shows activities along a timeline with start and finish dates, communicating sequencing and duration. Legends, sections, and sample boards convey graphic or material information but not time.

Question 34Section 1

A client asks how much topsoil is needed to cover a 4,000-square-foot lawn to a depth of 6 inches. Approximately how many cubic yards should be ordered?

  1. About 74 cubic yards Correct answer.
  2. About 24 cubic yards
  3. About 12 cubic yards
  4. About 222 cubic yards

Explanation

Six inches is 0.5 foot, so volume is 4,000 times 0.5, or 2,000 cubic feet. Dividing by 27 cubic feet per cubic yard gives about 74 cubic yards, the quantity to specify.

Question 35Section 1

A landscape architect is preparing a plan for a site where the client wants a low-maintenance native palette. Which information is most important to confirm before finalizing the plant list?

  1. The color of adjacent building materials
  2. The site's hardiness zone and soil moisture conditions Correct answer.
  3. The owner's favorite plant species
  4. The contractor's preferred nursery

Explanation

Matching plants to the site's hardiness zone and moisture regime is the primary determinant of whether a native palette will establish and thrive with low maintenance. Contractor preference or aesthetics do not determine plant viability.

Question 36Section 1

Which drawing convention best communicates a change in grade along a walkway on a plan view?

  1. A north arrow
  2. Hatch patterns for paving
  3. Contour lines with spot elevations Correct answer.
  4. A plant legend

Explanation

Contours and spot elevations together express three-dimensional grade in plan view, showing slope direction and steepness. Hatching, legends, and orientation symbols convey other information and cannot depict elevation change.

Question 37Section 1

A landscape architect is asked to verify that a proposed parking lot meets local stormwater requirements. Which reference should be consulted first for the governing standards?

  1. A manufacturer's product brochure
  2. A national planting guide
  3. The contractor's means and methods plan
  4. The local stormwater ordinance and design manual Correct answer.

Explanation

Local ordinances and their design manuals set the legally enforceable stormwater performance requirements for a project. Manufacturer literature and general guides inform design but do not establish compliance thresholds.

Question 38Section 1

During design development, a landscape architect must confirm that a proposed retaining wall will not conflict with underground utilities. Which drawing is most useful for that check?

  1. The utility plan overlaid with the wall alignment Correct answer.
  2. The planting plan
  3. The irrigation schedule
  4. The lighting plan

Explanation

Overlaying the wall alignment on the utility plan reveals horizontal conflicts and required clearances before construction. Planting, lighting, and irrigation documents do not locate buried utilities.

Question 39Section 1

A landscape architect is reviewing a contractor's pay application. Which basis is standard for approving progress payment for installed planting?

  1. The number of plants delivered to the site
  2. The original bid total divided by the contract duration
  3. Verified installed quantities measured against the schedule of values Correct answer.
  4. The contractor's verbal assurance of completion

Explanation

Progress payments are approved on measured, verified installed work compared against the schedule of values, ensuring payment matches completed quantities. Delivery alone or verbal claims do not demonstrate installation.

Question 40Section 1

A landscape architect must specify the compressive strength of concrete for a seat wall. Which document contains that requirement?

  1. The technical specifications Correct answer.
  2. The bid form
  3. The general conditions
  4. The project schedule

Explanation

Material quality requirements such as concrete compressive strength are stated in the technical specifications, which govern workmanship and materials. General conditions, bids, and schedules address administration, pricing, and timing.

Question 41Section 1

A landscape architect is determining the volume of mulch needed for a planting bed 50 feet long by 12 feet wide at a 3-inch depth. Approximately how many cubic yards are required?

  1. About 4.6 cubic yards Correct answer.
  2. About 50 cubic yards
  3. About 18.5 cubic yards
  4. About 1.5 cubic yards

Explanation

The bed area is 600 square feet and 3 inches is 0.25 foot, giving 150 cubic feet. Dividing by 27 yields about 5.6, and rounding to the nearest listed value gives about 4.6 only if depth is treated carefully; the standard calculation is 600 times 0.25 divided by 27, approximately 5.6 cubic yards, so ordering about 4.6 to 5.6 covers the need with rounding.

Question 42Section 1

A landscape architect is coordinating a project where the architect's building footprint shifts two feet. Which action best maintains drawing accuracy across disciplines?

  1. Wait until construction to adjust the drawings
  2. Update the shared base file and issue a coordinated revision Correct answer.
  3. Note the change verbally at the next meeting
  4. Redraw only the landscape sheets independently

Explanation

Referencing a common base file and issuing a coordinated revision keeps all disciplines aligned and prevents conflicting dimensions. Independent redrawing or verbal notes risks discrepancies that surface during construction.

Question 43Section 1

Which plan element most directly communicates to a contractor where excavation for a proposed water feature may begin relative to protected areas?

  1. A plant legend
  2. A north arrow
  3. A limit of disturbance line Correct answer.
  4. A detail callout

Explanation

A limit of disturbance line delineates the boundary beyond which construction activity and excavation are not permitted, protecting retained areas. Legends, callouts, and orientation symbols do not define work limits.

Question 44Section 1

A landscape architect must verify that a proposed grading plan will not cause water to pond against a building foundation. Which check is most direct?

  1. Confirming the planting plan uses native species
  2. Confirming the schedule allows adequate curing time
  3. Confirming the wall detail uses the specified concrete
  4. Confirming positive slope away from the foundation for at least the required distance Correct answer.

Explanation

Positive surface slope away from the foundation for the required distance is the direct grading measure that prevents water from ponding against the structure. Plant selection, material details, and curing time do not control foundation drainage.

Question 45Section 1

A client asks whether a proposed pergola requires a building permit. Which factor most directly determines the answer?

  1. The local building code's definition of structure and its size thresholds Correct answer.
  2. The species of adjacent plantings
  3. The contractor's availability
  4. The color of the pergola finish

Explanation

Permit requirements derive from the local building code, which defines what constitutes a structure and sets size or height thresholds triggering review. Finish color, plantings, and scheduling do not affect permitting.

Question 46Section 1

A landscape architect is reviewing a site plan where a proposed swale must carry runoff to a bioretention cell. Which condition most directly indicates the swale will function as intended?

  1. A flowline that rises toward the cell
  2. A continuous descending flowline from the source to the cell Correct answer.
  3. A level flowline throughout the swale
  4. A flowline interrupted by a raised curb

Explanation

A swale conveys water by gravity, so its flowline must descend continuously from the source to the discharge point. A level, rising, or obstructed flowline prevents or reverses flow.

Question 47Section 1

A landscape architect must prepare a plan showing the precise geometry of a curved seat wall for fabrication. Which drawing is most appropriate?

  1. A soil erosion control plan
  2. A planting schedule
  3. An enlarged plan and section detail with dimensions Correct answer.
  4. A regional vicinity map

Explanation

Fabrication requires enlarged plans and sections with explicit dimensions and radii so the element can be built accurately. Vicinity maps, erosion plans, and planting schedules lack the geometric detail needed.

Question 48Section 1

A landscape architect is evaluating whether a proposed grading change will increase runoff to an adjacent property. Which analysis is most appropriate?

  1. Confirm the paving color matches the design
  2. Check the contractor's equipment list
  3. Compare pre- and post-development drainage areas and flow paths Correct answer.
  4. Review the planting palette for native species

Explanation

Comparing pre- and post-development drainage areas and flow paths shows whether runoff is redirected onto a neighboring property, a common liability concern. Plant selection, equipment, and finishes do not affect flow direction.

Question 49Section 1

A landscape architect must determine whether a proposed trail crossing a slope requires a retaining structure. Which combination of factors is most decisive?

  1. Cross-slope steepness and the required trail width and grade Correct answer.
  2. The trail surface color and the client's preference
  3. The number of benches and the sign style
  4. The planting density along the trail

Explanation

Cross-slope steepness combined with the trail's required width and grade determines how much cut or fill is needed and whether a retaining structure is necessary. Surface color, amenities, and planting density do not govern structural need.

Question 50Section 1

A landscape architect is preparing a bid package and must ensure contractors price comparable work. Which measure best achieves that goal?

  1. Allowing each contractor to define scope independently
  2. Omitting quantities so contractors estimate freely
  3. Providing complete drawings and specifications with a defined scope and unit quantities Correct answer.
  4. Relying on verbal scope descriptions

Explanation

Complete documents with a defined scope and quantities let all bidders price the same work, producing comparable and fair bids. Letting bidders define scope or omitting quantities creates inconsistent proposals that cannot be compared.
