Welcome to Business (Stormwater) Registration for the Stormwater Compliance Program.  Although the County of Riverside does not have a business license program, if you are conducting business as defined in Ordinance No. 857 within the unincorporated areas of the County of Riverside you are required to register for a Business (Stormwater) Registration for stormwater compliance.  Any person who does not register is subject to the procedures and penalties set forth in Ordinance No. 857.
