If these are not kept clean and free of debris, localized flooding can occur and more sediment can build up in the river channel. If you see dumping or debris in ditches or drains in the City, contact Garden City's Environmental Division at (208) 472-2949. Learn More On How to Help Here. ACHD is in charge of the storm drains in Ada County. You can find storm drains near you here: ACHD Storm Drain Locations
