Clark County enforces strict dust control rules for construction and grading projects. These rules help reduce airborne dust pollution. One major requirement involves posting a dust control sign at the project site. These signs provide details about the permit and responsible parties. Signs must be visible to the public and inspectors. The Clark County Department of Environment and Sustainability outlines exact size requirements.

According to regulations, project size determines sign size. Smaller projects need smaller signs. Larger grading areas need oversized signs. Signs must include the permit number, project contact information, and dust control responsibilities. Projects disturbing over ten acres must follow enhanced sign size rules. Every sign must remain readable and weather-resistant throughout the project timeline.

Required Dust Control Sign Sizes by Project Scope

For projects under ten acres, Clark County requires a 4-foot wide by 4-foot high sign. This 4×4 sign must be placed in a prominent location. The placement should allow easy viewing from a public road or entrance. The sign should be posted before any dust-generating work begins. It must remain visible until the project concludes.

Projects larger than ten acres need a 4-foot tall by 8-foot wide sign. This larger 4×8 sign provides more visibility and space for required information. Clark County uses these rules to ensure accountability on large projects. Oversized signs allow inspectors and the public to report violations. Following these size requirements ensures permit compliance and avoids fines or project delays.

Dust Control Permit Sign Content Requirements

Sign content matters just as much as size. Every dust control sign must include required permit information. It should clearly display the Clark County dust permit number, responsible party name, and 24-hour contact number. It must also include a statement encouraging the public to report dust violations.

Signs must use minimum 2-inch tall lettering in a legible font. For 4×8 signs, letters should be larger for visibility. All text should contrast sharply with the background color. Most contractors use white backgrounds with black or red lettering for best readability. Bilingual signs are recommended but not always required. English text is mandatory.

Why Proper Signage Matters in Las Vegas Projects

Clark County uses dust control signage to monitor environmental impacts. These signs help enforce air quality regulations in Las Vegas. Non-compliance with sign size and content leads to violations. Fines range from hundreds to thousands of dollars. In worst cases, the county may shut down projects entirely.

Contractors should order custom dust control signs from local print providers. Many sign shops in Las Vegas offer same-day dust permit sign printing. Custom signs can include logos or additional contact information. For long-term projects, signs should use UV-resistant and waterproof materials. This ensures the sign remains readable over months of exposure.
