Boulder City FAQ
Do I need a stormwater permit for my construction project?
Projects disturbing one acre or more require a NDEP Construction Stormwater Permit and SWPPP. Smaller projects must still comply with Boulder City BMP requirements during construction.
Why is stormwater important in the desert?
Monsoon rains in July-September cause flash floods in desert washes. Hard, compacted soil sheds water rapidly. Stormwater controls protect property, public safety, and downstream Lake Mead water quality.
Paradise FAQ
Can I wash my car in my Clark County driveway?
Soapy wash water flowing to the street storm drain is an illicit discharge under Title 24. Wash on grass or gravel that infiltrates on-site, or use a commercial car wash that recycles wastewater.
Does my Clark County construction site need a stormwater permit?
Yes, if the site disturbs 1 acre or more (including smaller sites part of a larger common plan). Apply for the NDEP Construction Stormwater General Permit and prepare a SWPPP before ground disturbance.
