β Complete Checklist
Site Assessment
- βMark property lines and verify setback requirements with Portland's zoning codes.
- βIdentify existing drainage patterns and note any low spots or standing water.
- βCheck soil type (clay, loam, or sandy) using a simple jar test β Portland often has heavy clay.
- βMap sun exposure across your yard, noting full sun, partial shade, and deep shade areas.
- βLocate underground utilities via Oregon's 811 call-before-you-dig service.
- βMeasure slopes and grade changes β note any areas steeper than 2:1 that may need retaining walls.
- βIdentify existing hardscape conditions: cracks in concrete, settling patios, or moss on pavers.
Design & Layout
- βList primary uses: dining, lounging, play area, vegetable garden, fire pit, or outdoor kitchen.
- βSketch a rough bubble diagram showing where you want each zone relative to the house.
- βConsider traffic flow β ensure walkways are at least 4 feet wide for two people to pass.
- βPlan for ADA accessibility if needed β keep paths smooth and slopes β€1:20.
- βAccount for views and privacy β note bare windows or neighbor sight lines you want to block.
- βThink about seasonal use β Portland winters are wet; plan covered areas or pergolas for yearβround enjoyment.
Hardscaping Considerations
- βChoose materials that resist Pacific Northwest freeze-thaw cycles: flagstone, permeable pavers, or textured concrete.
- βDecide on a patios vs. decks based on moisture exposure β decks require rot-resistant cedar or composite.
- βPlan for proper base drainage under pavers (4β6 inches of crushed rock and geotextile fabric).
- βConsider lighting placement for safety: step lights, path lights, and accent uplighting on specimen trees.
- βEvaluate natural stone vs. manufactured stone for retaining walls β manufactured often weighs less and installs faster.
- βInclude at least one water-managed feature like a rain garden or dry well to handle Portland's annual 36 inches of rain.
Plant & Irrigation Planning
- βSelect plants suited to Portland's hardiness zone 8b: evergreen huckleberry, sword fern, and vine maple.
- βGroup plants by water needs β high, moderate, low β to simplify irrigation zones.
- βAvoid invasive species per Oregon's Noxious Weed List: English ivy, Himalayan blackberry, and butterfly bush.
- βConsider native plants for lower maintenance and pollinator support: Oregon grape, red-flowering currant.
- βPlan irrigation system type: drip for planters, rotor sprayers for lawns, and bubblers for shrubs.
- βInclude a rain sensor or smart controller to adjust watering based on Portland's frequent rain events.
- βDesign for four-season interest: spring bulbs, summer perennials, fall color trees, and winter bark/stems.
π‘ Pro Tips from the Experts
π‘ Start with Drainage β Not Decor
In Portland's wet climate, addressing drainage first prevents future landscaping failures: install French drains or dry creek beds before laying sod or patios.
π‘ Choose Permeable Pavers Near Trees
Avoid solid concrete near mature trees β permeable pavers allow water and oxygen to reach roots, reducing sidewalk heave and tree stress.
π‘ Think Vertical in Small Yards
When space is tight, use green walls, espaliered fruit trees, or trellises with climbing hydrangea to create privacy without sacrificing floor area.
π‘ Specify 'Low-Maintenance' Plants for Rentals
If you plan to move in a few years, choose drought-tolerant, slow-growing shrubs and perennial grasses β less trimming, less worry.
π‘ Schedule Hardscape Work in Late Summer
Portland's best window for concrete and paver installation is JulyβSeptember when soil is dry and overnight lows stay above 50Β°F to avoid frost heave.
