Board Governance & Components

Landscaping & Irrigation in the Reserve Study

Landscaping is where the line between the operating budget and the reserve study gets blurry — and boards often get it wrong in both directions. Routine mowing and planting are operating costs, but irrigation systems, hardscape, and major landscape features are reserve components. Sorting out which is which is the key to planning landscaping correctly. Here's how.

The Operating-vs-Reserve Line

The fundamental distinction: operating expenses are recurring routine costs, while reserve components are major items that are replaced periodically. Applied to landscaping:

Operating budget (routine, recurring):

• Mowing, trimming, and regular maintenance
• Seasonal planting and annual flowers
• Fertilizing, weeding, and pest control
• Routine irrigation repairs and water bills
• Mulch replenishment

Reserve study (major, periodic replacement):

• Irrigation systems — controllers, valves, pumps, and main-line components that wear out and need replacement
• Hardscape — walkways, retaining walls, decorative walls, pavers, and similar built features
• Major trees — removal and replacement of significant trees (and the liability/cost of large tree work)
• Landscape lighting — overlapping with electrical
• Water features — fountains, ponds, and their equipment
• Significant landscape structures — pergolas, gazebos, monument signs

Getting this line right matters: putting reserve items in operating understates reserves and inflates the operating budget, while putting routine costs in reserves does the reverse. A good reserve study draws the line correctly.

Irrigation: The Real Reserve Component

The most significant landscaping reserve item is usually the irrigation system, because it has substantial components that genuinely wear out:

• Controllers — increasingly "smart" and electronic, with finite (and obsolescence-prone) lives
• Valves and zones — wear out and need replacement
• Pumps — where present, significant components
• Main lines and distribution — eventually need replacement
• Backflow prevention — required and periodically replaced

Routine irrigation repairs are operating; the periodic replacement of these system components is reserve. Treating irrigation as purely an operating concern is a common error that leaves its eventual major-component replacement unfunded.

Hardscape and Trees

Hardscape — retaining walls, decorative walls, walkways, and major pavers — are durable but eventually need repair or replacement, especially in freeze-thaw and expansive-soil areas where ground movement cracks them. These belong in reserves.

Major trees are a subtler reserve and risk item: large trees eventually need removal (expensive, especially near buildings) and sometimes replacement, and they carry liability if they fail. While routine tree trimming is operating, the periodic major tree work is closer to a reserve/capital consideration. Some studies handle significant tree programs as a reserve line.

Climate and Water Considerations

• Drought and water restrictions — in Western and Southwestern communities, water cost and restrictions drive landscape decisions, sometimes prompting capital conversions to drought-tolerant landscaping (xeriscaping), which can be a capital project
• Smart irrigation upgrades — water-saving controller upgrades can be capital improvements with operating savings
• Storm and freeze damage — can require landscape and irrigation repairs

Planning Landscaping in Reserves

1. Draw the operating-vs-reserve line correctly — routine care is operating; major periodic replacement is reserve
2. Reserve for the irrigation system — controllers, valves, pumps, main lines are real components
3. Include hardscape — walls and walkways, especially in ground-movement climates
4. Consider major trees — removal/replacement and liability
5. Account for landscape lighting and water features — finite-life components
6. Plan capital landscape conversions — e.g., drought-tolerant conversions in water-stressed areas

The Bottom Line

Landscaping straddles the operating-reserve line, and getting it right means recognizing that while routine care is operating, the irrigation system, hardscape, major trees, and landscape features are genuine reserve components. The most common error is treating irrigation as purely operating and leaving its major-component replacement unfunded. Draw the line correctly, reserve for the irrigation system specifically, and include hardscape and significant landscape features.
