Screen the View, Not the Whole Property Line
The default privacy request in Naperville sounds like this: plant a row of arborvitae along the back line. It is the most common approach in the western suburbs and usually the wrong one. It costs the most, takes the longest to work, blocks the least of what actually bothers you, and fails all at once when deer, bagworm, or a wet winter takes out the row.
Privacy is a geometry problem before it is a plant problem. Solve the geometry and you need a fraction of the material.
First Question: What Are You Actually Screening?
“More privacy” is not a design brief. Walk the yard and name the specific thing. The answer changes everything downstream.
- A second-story window looking down. This is the hardest case. You are blocking a sightline that starts 20 feet up, so anything under 15 feet tall does nothing. Often the real answer is overhead: a pergola, an arbor, or the canopy of a well-placed tree, not a taller hedge.
- A patio sightline. Someone sitting is looking from about 40 inches off the ground. A 6-foot screen placed near the patio blocks far more than a 12-foot screen at the property line.
- Headlights. These are low and moving. A 30-inch berm or a low masonry wall handles them completely, and plants alone rarely do because headlights pass under the canopy.
- A neighbor’s deck or second-floor door. Elevated and fixed. Screen at the source angle, and often a single well-sited tree does the job that 60 feet of hedge could not.
- Street noise. Be honest here. Plants do not meaningfully block sound. Mass and distance do, which is why a berm helps and a hedge does not. What plants do is remove the visual reminder, which most people experience as quieter.
The Sightline Geometry That Saves You Money
A screen blocks a cone of view. The closer it sits to your eye, the wider the cone it covers. Move it away and the same object covers less. In practice, a 10-foot-wide panel or plant group set 8 feet from where you sit can block the same view as a 40-foot run of hedge at a property line 60 feet away.
So the method is simple. Sit where you actually sit, have someone stand where the offending view is, then hold up a piece of cardboard and walk it toward yourself until the view disappears. That spot is where your screen goes, and it is almost always closer to the house than homeowners expect. This is why screening belongs in the same conversation as patio and backyard entertaining space layout: the seating position defines the requirement.
Why the Solid Evergreen Row Is a Risk
A single-species hedge is a monoculture, and monocultures fail as a unit. When one plant in a 15-plant arborvitae row goes down to bagworm or root rot, the others are usually next, and a gap-toothed hedge looks worse than no hedge. Replacing it means starting the timeline over from zero.
A mixed screen using three or four species in overlapping groups fails gracefully: lose one plant and the layered mass absorbs it. Mixed screens also read as designed rather than institutional.
Evergreen Options, Assessed Honestly for Chicagoland
Arborvitae
Fast, dense, inexpensive, and the reason most privacy plantings look the way they do. Also the most deer-preferred evergreen in the region. Where deer pressure is real, arborvitae gets browsed to a bare stem line at exactly the height you needed screening. If deer are present, either skip it or plan on a serious protection routine.
Spruce
Norway and Colorado spruce are tough, deer-resistant, and grow large. Size is the catch: a spruce reaching 20 feet wide will not stay in a 10-foot side yard. Spruce also holds needles poorly at the bottom as it ages, so a screening row often loses its lower third by year fifteen.
Yew
Excellent in shade, tolerant of pruning, dense, and long-lived. Slower than arborvitae, and it will not survive standing water in heavy clay. Also a deer favorite in winter.
Boxwood
Useful for low screening and definition, not tall privacy. Broadleaf evergreens in zone 5b are the most prone to winter burn, with foliage desiccating in cold wind and winter sun while frozen roots cannot resupply moisture. Site them out of the northwest wind.
Upright junipers
Salt tolerant, sun loving, deer resistant, and comfortable in poor soil. Narrow forms hold a tight column, which makes them useful in a side yard where width is limited.
Building a Layered Screen
1. Set the evergreen backbone
Evergreen mass carries the five-month dormant season and does the actual blocking in January. Place it in staggered groups, not a straight line, and give each plant its true mature width. Evergreens set too close shade each other out from the inside and go bare at the contact points permanently.
2. Add deciduous mass in front
Large shrubs and small ornamental trees add depth, seasonal change, and volume for a lower cost per foot than evergreens. They also break up the wall effect that a pure evergreen run creates.
3. Bring in structure where plants are slow
A cedar panel, a slatted screen, a section of fence, or a pergola with a partial side works the day it is installed. A short run of structure at the critical sightline with planting around it gives immediate relief and a screen that improves over time. A custom shade structure carrying a privacy panel resolves overhead sightlines no plant can reach.
4. Use grade if you have it
A berm gives you free height. Three feet of well-shaped berm makes a 6-foot shrub function like a 9-foot one, and it handles headlights on its own. Berms need to be long and gentle relative to their height to look natural, and they need drainage thought through so you do not redirect water onto a neighbor. That grading work belongs with the broader conversation about regrading an aging landscape and retaining structures.
Screening Options Compared
| Approach | Time to effective | Relative cost | Watch-outs |
|---|---|---|---|
| Single-species evergreen row | 4 to 8 years | Low to moderate per foot | Fails as a unit; deer browse; needs full mature width or it goes bare inside |
| Mixed layered screen | 3 to 6 years for real effect | Moderate to high | Needs more depth of bed; requires a plan so it does not look random |
| Fence or privacy panel | Immediate | Moderate | Height limits by ordinance; hard edge unless softened with planting |
| Pergola or overhead structure | Immediate | High | Only tool that addresses second-story sightlines; needs footings and permits |
| Berm plus planting | 2 to 5 years | Moderate | Requires space and soil volume; must not push water to a neighbor |
Three Things That Change the Plan
Setbacks and easements decide what is possible before design does. Most suburban lots carry a utility easement along the rear or side line, often 10 feet wide, sometimes with a drainage swale in it. You can usually plant there, but the utility can remove anything in it without replacing it, and no structure goes there. Fence height and placement are governed by ordinance and frequently an HOA. Pull the plat of survey before choosing plants, and call for utility locates before digging.
Screening is seasonal, and winter is when you need it. Deciduous material drops in October and does not return until May. Those are exactly the months when leaves are off the neighbor’s trees too, sightlines open up, and everyone is looking at each other’s yards. Any screen that matters year-round needs evergreen or built structure carrying it, which is the same logic behind four-season landscape structure.
Screening a whole line reads as defensive; screening a view reads as designed. A continuous green wall around a suburban backyard makes the yard feel smaller and slightly hostile. Breaking the screen into masses, leaving intentional gaps where the view is fine, and letting the eye travel makes the same yard feel larger while blocking everything that actually bothered you.
Privacy Across the Western Suburbs
- Naperville: Mature canopy already screens at height in older neighborhoods, so the work is in the 4 to 10 foot band. Tighter newer subdivisions need narrow columnar material and structure more than mass planting.
- Wheaton and Glen Ellyn: Grade changes are common and are the cheapest privacy asset on the property when the design uses them.
- Aurora and Plainfield: Open, wind-exposed lots where evergreen screens need staggered placement rather than a single exposed line.
- Lisle, Downers Grove, Warrenville, and Bolingbrook: Deer pressure varies block to block near forest preserve corridors. That single fact should decide whether arborvitae is on the list at all.
Get the Sightlines Right the First Time
CB Conlin Landscapes has been solving privacy on western suburb lots since 1985, and the screens that work were the ones designed from the seat, not from the property line. You can see how layered screening and structure come together across our completed project gallery. When you are ready to work out what your yard actually needs, start your privacy project with a consultation and we will map the sightlines with you on site. The same efficiency thinking applies here as in a low maintenance front yard design: less material, better placed, doing more work.
Frequently Asked Questions
How tall does a privacy screen need to be?
It depends on distance and eye height. For a seated patio with the screen 8 to 10 feet away, 6 feet is usually plenty. Screening the same patio from a property line 50 feet off may take 12 to 15 feet and still accomplish less. Measure the sightline first.
Will arborvitae work in my yard?
If you have no meaningful deer pressure, decent drainage, and full sun, it performs well and grows quickly. If deer travel your block, expect browsing up to about 6 feet on the accessible sides, which removes the screening exactly where you wanted it. Ask neighbors what they see rather than guessing.
How long until a plant screen actually works?
Plan on three to six years for a mixed screen to read as solid, longer for slower evergreens installed at modest sizes. Larger stock shortens that but costs much more and establishes more slowly. If you need privacy this season, part of the solution has to be built rather than grown.
Can I plant right on the property line?
You can plant on your side of it, but plan for mature width. A shrub with an 8-foot spread planted 2 feet off the line will extend 2 feet into the neighbor’s yard, and they are legally entitled to cut what crosses. Set the screen far enough in that the mature plant stays on your property.
What about privacy from a second-story window?
Accept that a hedge will not solve it. What works is overhead structure, a tree whose canopy intercepts the downward sightline, or a screen positioned very close to the area you are protecting. A pergola with a solid or louvered section is usually the fastest answer.
Glossary
Sightline
The straight line between a viewer’s eye and the object being seen. Privacy design works by interrupting specific sightlines rather than enclosing an area, which is why screen placement matters more than screen size.
Berm
A shaped mound of soil built to add elevation. Berms raise plant height, block low sightlines such as headlights, and add mass, but they must be gently sloped and drainage-planned so they do not redirect water onto adjacent property.
Winter burn
Foliage damage on evergreens caused by cold wind and winter sun drawing moisture out of leaves while frozen soil prevents resupply. It is most severe on broadleaf evergreens and on exposures facing winter wind or reflected heat from pavement.
Utility easement
A recorded strip of land, commonly along rear or side lot lines, where a utility retains access rights. Planting is usually permitted but is removable without replacement, and permanent structures are not allowed.
