How to Phase a Property, In Order

Nearly every expensive mistake in residential land work is a sequencing mistake rather than a taste mistake. This guide gives the seven-phase order in which each phase makes the next one cheaper, a rough budget allocation, and the three things to settle before you hire anyone.

The sequence

Access and water come first, because they shape where vehicles, equipment, and water move, and they are the most disruptive to change later. Grading and earthworks come second, since heavy machinery destroys finished work and soil should move while there is nothing to protect. Structure and hardscape are third: walls, patios, steps, and utilities, built to the resolved grade rather than on top of an unresolved one. Soil is fourth, because amendment and biology go in after construction compaction is finished. Trees and woody plants are fifth, planted first among plantings because they take longest to return value and are hardest to add later. The herbaceous layer is sixth, fast to establish and cheap to revise, so it goes late. Systems and finish come last: lighting, irrigation, and furnishing, the layer people want first and should buy last.

Rough budget allocation

As a general planning frame on a whole-property project, expect roughly 15 to 20 percent to design and site work, 30 to 40 percent to grading, drainage, and structure, 25 to 35 percent to soil and planting, and 10 to 15 percent to systems and finish. Properties with existing drainage problems shift heavily toward the second bucket, and that is money well spent even though none of it is visible when the work is done.

Three things to do before you hire anyone

Write down what the property is for, whether privacy, food, habitat, entertaining, resale, or some ranked combination, because a designer cannot value engineer a program you have not defined. Set a total number and a horizon, since phasing over four years at a realistic annual figure produces a better property than compressing the same budget into one season. And pull your site data, because soil, flood zone, sun, and rainfall are all publicly available, and arriving with them changes what kind of proposal you get back.
