HI Landscape study plan

HI Landscape · Give each week a clear focus.

8 weeks · About 6 hours per week

Week 1

Landscape Design and Planning

  • Map the seven domain weightings against a self-rating scale from 1 to 5 and rank your weakest three subtopics inside Domain 1

  • Define site-analysis inputs (sun and shadow paths, prevailing wind, views and borrowed landscape, circulation desire lines) and sketch a bubble diagram for a 500 square meter residential lot

  • Convert a client program (outdoor kitchen, play lawn, screening, accessible path) into a functional zoning diagram with primary, secondary, and service zones

  • Draft a planting-design intent statement that ties each zone to a spatial purpose rather than to plant names

Your checkpoint

One hand-drawn or CAD site plan at 1:100 with zoning diagram, circulation arrows, and a one-page design intent statement

Week 2

Landscape Design and Planning

  • Apply scale, proportion, and rhythm principles to critique two of your own schematic plans and annotate three specific revisions on each

  • Calculate impervious coverage and open-space ratios for a small commercial plaza layout and compare the result to a typical local zoning threshold

  • Sequence a design process from client interview through concept, design development, and construction documentation, listing the approval gate at each stage

  • Produce a planting plan legend that specifies botanical name, common name, mature size, spacing, and quantity for at least 15 plants

Your checkpoint

A design development package: revised plan, planting legend with 15-plus entries, and a written design rationale of roughly 300 words

Week 3

Plant Selection and Horticulture

  • Build a plant-selection matrix scoring 20 candidate species against hardiness zone, mature size, water demand, sun exposure, soil pH tolerance, and maintenance level

  • Match at least eight species to specific microclimates on your Week 1 plan and justify each placement in writing

  • Classify the 20 species by growth habit, evergreen versus deciduous, and root habit, and flag any that conflict with hardscape or utilities

  • Distinguish the cultural requirements of turf, groundcover, shrub, and canopy layers and state one failure mode for each layer

Your checkpoint

A 20-species selection matrix plus a marked-up planting plan showing species codes matched to microclimate notes

Week 4

Plant Selection and Horticulture & Site Assessment and Grading

  • Read a topographic map with 0.5 meter contours and identify ridge, valley, and drainage-shed lines, then mark the likely flow path across the site

  • Compute slope percentage between ten point pairs and classify each as walkable, plantable, or requiring a retaining structure

  • Specify soil amendment and drainage correction for one compacted area and one poorly drained area on your plan

  • Select and schedule plants tolerant of the wet and dry extremes you identified, with at least three species per extreme

Your checkpoint

A grading and drainage overlay on your site plan with slope calculations, flow arrows, and a revised planting schedule reflecting the soil and moisture findings

Week 5

Hardscape Construction and Materials

  • Compare four paving materials on load capacity, permeability, slip resistance, freeze-thaw behavior, and installed cost per square meter

  • Detail a typical segmental paver assembly from subgrade through bedding sand and joint sand, labeling each layer and its compaction requirement

  • Size a modular retaining wall for a 1.2 meter height difference, including base course width, embedment, drainage gravel, filter fabric, and weep points

  • Identify three common hardscape failure modes (settlement, heave, efflorescence) and write the construction detail that prevents each

Your checkpoint

Two construction details drawn at 1:10 (paver edge restraint and retaining wall section) with a material comparison table of four options

Week 6

Hardscape Construction and Materials & Irrigation and Drainage

  • Lay out a drip and spray irrigation zone plan for your site, assigning each hydrozone a precipitation rate and controller station

  • Calculate total flow and pressure demand for the design and check it against a stated available supply of 25 liters per minute at 3 bar

  • Design a surface and subsurface drainage scheme with pipe sizing, minimum slope, catch basin locations, and an overflow route to a legal discharge point

  • Write a winterization and seasonal adjustment procedure for the system you designed

Your checkpoint

An irrigation and drainage plan with a hydrozone table, flow and pressure calculation sheet, and a one-page seasonal operating procedure

Week 7

Project Management and Estimating & Safety and Regulations

  • Build a quantity takeoff from your own plan for paving area, wall face area, plant counts, and mulch volume, then price it with unit costs and a 12 percent contingency

  • Draft a 12-line-item work breakdown with sequence, duration, and predecessor for a four-week installation

  • List the site-safety controls required for excavation, equipment operation, and utility locating, and state the trigger for each

  • Identify the permits, utility locates, and accessibility requirements that apply to your project and note who is responsible for each

Your checkpoint

A one-page estimate with takeoff quantities and totals, a Gantt-style schedule, and a permit and safety checklist

Week 8

Landscape Design and Planning & Plant Selection and Horticulture & Hardscape Construction and Materials & Irrigation and Drainage & Site Assessment and Grading & Project Management and Estimating & Safety and Regulations

  • Complete 120 mixed practice questions under timed conditions and log every miss by domain and error type

  • Re-teach your three weakest subtopics from source material and write a five-line summary of each in your own words

  • Recompute the two calculations you missed most often (slope percentage, irrigation flow, or takeoff quantity) until you can do each correctly three times in a row

  • Assemble a one-page formula and reference sheet you can mentally reconstruct on exam day

Your checkpoint

A scored practice exam log with error analysis by domain and a one-page formula and reference sheet

Milestones

Week 2: You can produce a zoned concept plan with a defensible design rationale in under 90 minutes without notes

Week 4: You correctly read contours and compute slope percentage on ten out of ten practice point pairs

Week 6: Your irrigation flow calculation and drainage slope layout are internally consistent and you can explain every assumption aloud in two minutes

Week 8: Timed practice score is at or above 75 percent overall with no single domain below 60 percent
