Becoming a homeowner also means becoming a landowner. Ever since the first American homes were built, having a piece of land to call one’s own has been a sign of prosperity, a dream fulfilled.
But the dream comes with responsibilities, because the decisions you make about the preparation of your lot and your landscaping will have a lasting impact on the durability of your home, the cost
of its upkeep – and the environment.
It helps to understand how your house and yard interact with one another and with the local climate. In this article, we’ll look at the land side of the land/house interaction. We’ll
discuss materials, landscaping ideas, and the general lay of the land. You’ll find tips on what to do and what to leave alone, some things to think about, and some important questions to ask
your builder or developer.
SMART AESTHETICS Can you make your property more attractive, durable and functional? Yes – and if done properly, it will require less maintenance, and you’ll use less
water and energy. The key is to combine technology with common sense.
Work with the elements, and they’ll work for you. Your house, your lot, and the components of each, act as an integrated system. And your goal should be to allow the parts of this system to work
well together, in harmony with surrounding natural forces. After all, the rainfall that hits your roof can replenish your landscaping – or it can wash out your driveway. And the summer sun can
power your refrigerator and nourish your hedges – or it can overheat your home and wither your ornamentals.
If you’re planning a new house on an undisturbed lot, what does the terrain look like now? If you take advantage of the site’sexisting natural features, you’ll minimize disturbance
and preserve existing habitat. This money-saving principle will make your lot aesthetically pleasing, functional and low-maintenance.
Keep in mind that the existing terrain (builders call it the “existing grade”) and the plants that grow on it reflect thousands of years of evolution. When you build your home on it, the
only changes you really need are cleared spaces for the house, driveway and construction access, and adjustments that allow the land to better accommodate the rainfall that will run off your roof and
paved areas.
Of course you’ll also want to clear out dead and dying trees, and you probably want a lawn for play and relaxing. But whatever you do, don’t clear and scrape everything around the home
site and then plop down high-maintenance, non-native turf [see "Is the Grass Really Greener?" sidebar below].
The same applies in arid regions – but even more so. Desert plants are very fragile. Once disturbed they are difficult to reestablish, and take a long time to recover.

ASK YOUR BUILDER:
- How can I preserve the natural beauty of this site?
- Which trees can you keep?
- Please flag the trees so I can see your plan on the ground before you cut.
- Why are you planning to clear such a large area?

THE GRADING PLAN After your home is built, the contractor will establish the final grade. Make sure that the ground slopes away from the house on all sides so that you minimize the
foundation’s exposure to moisture. Ponded water that seeps into the soil too close to the house can cause mold and, over time, even foundation damage. If your home is built into a hill, the
grading should channel water from the hill around – not toward – your foundation. The slope should be continuous, because any low points will hold water and breed mosquitoes – even
in arid regions. A gradual slope is best, to allow the soil to evenly and effectively capture moisture.

ASK YOUR BUILDER:
- How will you avoid leaving any low spots?
- Will you come back to regrade after every thing has had a chance to settle?

LANDSCAPING Conservation landscaping preserves water quality, provides natural beauty and habitat for local and migratory animals and conserves native plants. The structure, leaves,
flowers, seeds, and berries of locally native trees, shrubs and perennials provide food and shelter for native birds and other wildlife. The roots of these larger plants are typically deeper than
lawn grass, and better hold soil and capture rainwater.

IN DESIGNING A WATER AND MAINTENANCE-EFFICIENT LANDSCAPE ON A NEW LOT:
|
| |
- reduce the amount of turf and other irrigated areas;
- ensure water-efficient design of irrigation systems; and
- specify native or climate-appropriate landscape materials. This is called xeriscaping, a practice that saves on water, fertilizer, pruning, maintenance and overall costs
|
|
Remaining landscape areas that require irrigation should use water-efficient irrigation systems to minimize water use and maximize plant health. Such systems depend on efficient system design and
layout, optimized irrigation schedules and controls, and low-flow sprinkler heads to reduce water use.
Zero-maintenance? There’s no such thing. Even conservation landscaping requires some upkeep. Until they become established, new plants need watering and monitoring, especially during the first season.

On the side of a Maryland home, a raised bed of herbs and local flowers gives way to an indigenous lawn punctuated with sprays of wild buttercups and, beyond, native maple and pine.
This landscape wisely groups plants that prefer to have their feet wet closer to the run-off, while less thristy ones lay further up the grade.
Instead of the standard sea of bluegrass, a colorful arrangement of hardy perennials cuts down on water usage, while greatly enhancing this home’s curb appeal.
Hardscaping can be both beautiful and functional; reinforcing this newly planted garden’s structure, while providing easy accessibility and maintenance.
