Grading & Drainage: Las Vegas vs Paradise

Do I need a grading permit in Las Vegas?

Yes — any site preparation that moves dirt (clearing, grubbing, cutting, filling, grading) on private property in the City of Las Vegas requires an on-site grading permit from Las Vegas Public Works. Work in the public right-of-way or drainage facilities also requires a separate off-site permit and bond.

When does Las Vegas require a drainage study?

A drainage study (sealed by a Nevada-licensed PE) is required when the site is in a FEMA Special Flood Hazard Area, is adjacent to or impacted by a CCRFCD Master Plan facility, or receives flows from an off-site wash or drainage facility.

Do I need a dust permit to grade in Las Vegas?

Yes if the project disturbs 0.25 acre or more. Apply for a Dust Mitigation Permit through Clark County Department of Environment and Sustainability (DES) before disturbing the soil.

What is 'Early Grading' in Las Vegas?

Early Grading (also called 'at-risk grading') is an option to start on-site grading before the off-site permit is fully approved. The on-site grading plan must still be approved, and the contractor accepts the risk that off-site changes could require rework.

Do I need a grading permit for my Clark County backyard?

Usually only if you are moving more than 50 cubic yards, creating slopes over 5 feet, or working in a flood zone. Small planting or pool excavations typically do not need a separate grading permit.

Can my new driveway drain toward my neighbor?

Only up to the pre-development 10-year historic flow. Clark County drainage rules prohibit increasing runoff onto neighbors. If flooding occurs, you may face a civil nuisance claim and code enforcement.
