Roadwork and Paving Problems

Road paving, surfacing and pavement removal activities contribute to urban runoff pollution. This is because they take place right in the street, where urban runoff contamination can result from asphalt, saw-cut slurry or excavated material being washed into storm drains.

Rain or runoff then carries these toxic substances to the ocean through the storm drain system, posing a hazard to human and aquatic life.

Extra planning is required to store and dispose of materials properly and guard against stormwater and ocean pollution. This brochure will tell you how.

Solutions

Best Management Practices such as handling, storing, and disposing of materials properly can prevent pollutants from entering our rivers and oceans.

General Business Practices

  • Keep materials out of rain, runoff and wind. Store them under cover of temporary roofs or plastic sheets
  • Schedule excavation and grading work for dry weather
  • Develop and implement erosion and sediment control plans for embankments
  • Recycle all used oil, concrete, broken asphalt etc.

Equipment Maintenance

  • Keep all vehicles and equipment in good working order and inspect frequently for leaks.
  • Conduct all vehicle/equipment maintenance and refueling at one location away from storm drains.
  • Do not use diesel oil to lubricate equipment or parts.

Asphalt and Concrete Removal

  • After breaking up paving, be sure to remove all chunks and pieces. Recycle them at a crushing company.
  • Dispose of small amounts of dry concrete in the trash.
  • Make sure broken pavement does not come in contact with rainfall or runoff.
  • Shovel or vacuum saw-cut slurry and remove from the site. For disposal information contact the City of Davis Public Works Department at (530) 757-5686.
  • Cover or barricade storm drain openings during saw-cutting.

Asphalt and Concrete Disposal

Use a crushing company such as
Golden State Crushing 
5980 Outfall Circle 
Sacramento, CA 95828
916-381-4100
to recycle cement, asphalt and porcelain rather than taking them to a landfill.

During Construction

    • Cover catch basins and maintenance holes when applying seal coat, slurry seal, or fog seal
    • Use check dams, ditches or berms to divert runoff around excavations
    • Never wash materials from exposed aggregate concrete, asphalt, or similar treatments into a street, gutter or storm drain.
    • Collect and recycle excess abrasive gravel or sand. Call the City of Davis at (530) 757- 5686 for a recycling guide

Spills

    • Never hose down dirty pavement or surfaces. Clean up all spills and leaks using dry methods, or dig up and remove contaminated soil. For disposal information call the City of Davis at (530) 757-5686
    • Catch drips from paver with drip pans or absorbent material pl aced under the machine when not in use.

Where Does the Water Go?

What happens to water from rain, lawn watering, or car washing? This water, called stormwater or urban runoff, flows in to the City’s storm drainage system through over 2500 curbside catch basins – the openings located along street gutters. The water moves through the storm drain piping below our streets to our rivers, creeks, wetlands, sloughs, the delta, the bay, and eventually the Pacific Ocean.

Initially, much of this water fills the City’s detention and wildlife ponds which support an array of wildlife species. Other water flows through drainage ditches towards the northern and eastern edges of the City.

A portion of the stormwater that is collected in the City is conveyed to the Davis Wetlands where it is used to support this constructed wetlands system and all its wild inhabitants. Tours of the Davis Wetlands are offered the first Saturday of the month. For more information contact the Yolo Basin Foundation: (530) 757-4828.

Protect Our Wetlands

The Putah Creek bioregion and Yolo Bypass Wetlands near Davis comprise a delicately balanced ecosystem, home to numerous species of aquatic plants and animals crucial to the food web. These organisms can be harmed by discharges of material and wastes from concrete and mortar activities.

To remind everyone about the importance of preventing pollution of our stormwater, be it from concrete and mortar activities, or other sources, the City of Davis has installed these storm drain inlet markers near each drain:

storm-drain-markerThese markers are easy to install. So if you, your group, or organization would like to participate in this pollution awareness program, please contact City of Davis Public Works at (530) 757-5686.

Stormwater pollution can be extremely harmful to the health of the plants and animals with which we share this planet.

Help us to protect your water resources for current and future generations.

If you see anyone dumping questionable materials, please call City of Davis Public Works at (530) 757-5686. If it is an emergency, call 911.

Please keep our watershed clean!
