Paradise FAQ
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.
