Dust control on a graded parcel: where wind fencing helps and where it does not

Dust is regulated across the Phoenix metro because the region sits in a federal nonattainment area for particulate matter. On the large graded parcels around Queen Creek and San Tan Valley, it is also simply conspicuous: there are neighbours on the next parcel, roads on two sides, and nothing between them and your site.

This page is not a compliance document. The requirements belong to the county air quality authority, and note that Queen Creek spans Maricopa and Pinal counties, so which office covers your parcel is worth establishing early.

Where fencing fits

Screening a fence line is one of the accepted ways to cut windblown dust coming off a disturbed surface. A solid screened barrier on the upwind side reduces wind velocity at ground level, which reduces pickup.

Fencing is not, on its own, a dust control plan. The measures that usually do more:

• Water, applied on the schedule the plan requires. The workhorse.
• Stabilising ground that has been disturbed but is not being worked right now.
• Track-out control at exits. Out here this is the big one, because sites are reached by long dirt approaches and the material ends up on a paved road at the end of it.
• Keeping the disturbed footprint small, phasing the grading so less is open at once.
• Shutting down in high wind whenever your plan calls for it.

Screen on the fence helps every one of those and substitutes for none of them.

Track-out is the local version of this problem

On a site reached by a dirt access road, the complaint that arrives is usually not about the fence line at all. It is about the material tracked onto the paved road where your access meets it, and about the dust plume every truck raises coming and going.

Fencing does nothing for either. What helps: a proper track-out control device at the exit, watering the access road, and limiting truck speed on it. Worth saying plainly, because plenty of contractors buy screen and are surprised the complaints continue.

What it costs

Published on the pricing page, and the fence cost calculator will assemble it.

The open-ground wind trade-off

A screened fence is a sail. Bare chain link lets air through; screen makes the fence a solid surface and the wind load rises sharply. Monsoon microbursts, roughly mid-June through September, produce brief violent gusts.

On a parcel with nothing built upwind, that gust arrives unbroken. A screened line therefore needs:

• More ballast, at closer spacing
• Panels tied together so the line shares load
• Bracing on long straight runs
• In-ground posts wherever the ground allows, which on a job running months is usually the right call anyway

And sometimes it needs the screen off for July and August. The blown over page covers the mechanism.

The tension is real: the season with the worst dust is the season with the worst wind. Skipping the screen is not the fix; building a line heavy enough for the season is.

Practical setup on a Queen Creek parcel

1. Screen the sides that face neighbours and roads first if you are not screening everything.
2. Deal with the access road and the track-out point before you buy screen. That is where the complaints come from.
3. Get the fence up ahead of the grading, rather than once the first complaint lands.
4. Check the whole run once a week through monsoon. Bags creep, ties work loose, mesh rips at the grommets, and a ripped screen keeps peeling.
5. Line it up with the water truck. Screen slows what the wind lifts; watering keeps it from lifting at all.

What to expect on the call

Footage, which sides need screening, duration, whether the job runs through monsoon, what is downwind, and where the access road meets pavement. Ask us, or anyone quoting, for the line that stands up, and confirm with the air quality authority what fencing does and does not do for your dust obligations.
