Storm Water Utility

The City of Ukiah has adopted the Low Impact Development (LID) Manual that is utilized by Santa Rosa and Sonoma County (see City of Ukiah Resolution No. 2014-27). This Manual provides the technical design guidelines for development projects in the implementation of permanent storm water quality features.

For more information or to report issues with downloading the documents, please contact Benjamin Kageyama, Senior Civil Engineer via email at bkageyama@cityofukiah.com or call 707-463-6284.

City of Santa Rosa/County of Sonoma LID Manual, adopted by the City of Ukiah

As storm water flows over driveways, lawns, and sidewalks, it picks up debris, chemicals, dirt, and other pollutants. Storm water can flow into a storm sewer system or directly to a lake, stream, river, wetland, or coastal water. Anything that enters a storm sewer system is discharged untreated into the water bodies we use for swimming, fishing, and providing drinking water. Polluted runoff is the nation’s greatest threat to clean water.

Since the passage of the Federal Water Pollution Control Act, the quality of our Nation’s waters has improved dramatically. Despite this progress, however, degraded water bodies still exist. According to the 1996 National Water Quality Inventory, approximately 40 percent of surveyed U.S. water bodies are still impaired by pollution and do not meet water quality standards. A leading source of this impairment is polluted storm water runoff. In fact, according to the Inventory, 13 percent of impaired rivers, 21 percent of impaired lake acres, and 45 percent of impaired estuaries are affected by urban/suburban storm water runoff. Six percent of impaired rivers, 11 percent of impaired lake acres, and 11 percent of impaired estuaries are affected by construction site discharges.

The City of Ukiah recognizes that contaminants and impurities in storm water runoff are a major threat to the quality of our environment and our water supply. A five year management plan has been drafted and is in the process of being implemented. Posted below are the six areas in which the city is taking measures to reduce and protect against pollutants that storm water runoff carries to our creeks and rivers.

1. Public Education and Outreach
2. Public Involvement and Participation
3. Illicit Discharge Detection and Elimination
4. Construction Site Storm Water Runoff Control
5. Post-Construction Storm Water Management
6. Pollution Prevention and Good Housekeeping for Municipalities

Polluted Stormwater runoff can have many adverse effects on plants, fish, animals, and people.

  • Sediment can cloud the water and make it difficult or impossible for aquatic plants to grow. Sediment can also destroy aquatic habitats.
  • Excess nutrients can cause algae blooms. When algae die, they sink to the bottom and decompose in a process that removes oxygen from the water. Fish and other aquatic organisms can’t exist in water with low dissolved oxygen levels.
  • Bacteria and other pathogens can wash into swimming areas and create health hazards, often making beach closures necessary.
  • Debris – plastic bags, six-pack rings, bottles, and cigarette butts – washed into water bodies can choke, suffocate, or disable aquatic life like ducks, fish, turtles and birds.
  • Household hazardous wastes like insecticides, pesticides, paint, solvents, used motor oil, and other auto fluids can poison aquatic life. Land animals and people can become sick or die from eating diseased fish and shellfish or ingesting polluted water.
  • Polluted storm Water often affects drinking water sources. This, in turn, can affect human health and increase drinking water treatment costs.
