The majority of Cloverdale's businesses and residences are surrounded by lots of impervious surfaces such as roofs, driveways, and streetside parking spaces. Water run-off from every rainstorm runs over these impervious surfaces and picks up anything that it finds along the way. Contrary to common belief, stormwater does not get directed to our treatment facility like our sewer system. It goes directly to the Russian River. In a sense, Cloverdale's streets and gutters are part of the headwaters of the Russian River. This means garbage in the gutters, motor oil drips from cars, pet waste on sidewalks, pesticides, and other products that land on our streets flow directly into our river.

Though it seems like harmful runoff is an inevitable consequence of life in Cloverdale, small changes can have a big effect on reducing our impact on our river. Most storm drains in Cloverdale are marked with “No Dumping – Drains to Creek” labels to remind all of us that everything that lands in our streets eventually flows to our river. 

The City of Cloverdale has partnered with the Russian River Watershed Association (RRWA) to provide businesses and individuals with some helpful tips for protecting our river. The Urban Creek Care Guide (Guia para el Mantenimiento de Arroyos Urbanos) is available for FREE in English and Spanish at this link: Urban Creek Care Guide. Following the simple practices outlined in this guide will help keep our river clean...and our sidewalks...and our streets...and our businesses...and our schools...and our parks...you get the idea.

The State of California has determined that nonresidential and industrial customers are most likely to discharge water that does not comply with State and Federal Standards and has required the City of Cloverdale to inventory, monitor and inspect nonresidential and industrial uses who discharge water to the City Storm Drain System or Sewer System. The City of Cloverdale enacted the Cloverdale Wastewater Control Ordinance (CMC 13.16 et. seq.) and the Cloverdale Storm Water Ordinance (CMC 16.10 et. seq.) to provide a framework for preserving water quality.

All businesses connected to City utilities have been issued a Sewer Use Permit by the Public Works Department (CMC 13.16.100). This permit helps the City track how each business uses water and where the water goes. The permit also provides for periodic inspections. Most businesses will receive 2 inspections over the permit term of 5 years. A few high-impact businesses receive annual inspections. The Public Works Department contacts each business in advance to schedule inspections.
