Oregon Statute Makes Dangerous
Storm Drains Illegal

by Ray Thomas
Ray Thomas is a Portland bike lawyer.

In years past, storm drains have presented a significant hazard for bicyclists. Many drains were designed with metal spaces in the direction of travel that were wide enough to “eat” bicycle wheels. Newer designs have a crisscross pattern, eliminating the potential for getting a tire to wedged into the structure, launching the unwary rider over the handlebars.

The Oregon Revised Statutes contain a legal prohibition against dangerous storm grates that can be used by riders to nudge maintenance departments to install or redesign dangerous storm drains. Oregon Revised Statutes (ORS) 810.150 requires that storm drains be designed so that bicycles may pass safely:

“810.150. Drain construction; compliance with bicycle safety requirements; guidelines.
(1) Street drains, sewer drains, storm drains and other similar openings in a roadbed over which traffic must pass that are in any portion of a public way, highway, road, street, footpath or bicycle trail that is available for use by bicycle traffic shall be designed and installed, including any modification of existing drains, with grates or covers so that bicycle traffic may pass over the drains safely and without obstruction or interference.
(2) The Department of Transportation shall adopt construction guidelines for the design of public ways in accordance with this section. Limitations on the applicability of the guidelines are established under ORS 801.030.”

Unfortunately, the statute is modified by ORS 801.030 which “grandfathers” in “drains installed prior to 1975." This means that old style drains may escape the reach of the statute as a matter of law. However, it is almost impossible to tell when a drain has been installed so, for advocacy purposes, it is probably best to assume that the drain was installed after 1975, and is, therefore, subject to the prohibition on dangerous installations.

Note also that the section applies not only to public ways that are part of a “highway, road or street” but also to a “foot path or bicycle trail.” This means that if the dangerous grate is in a location where bicycles may lawfully pass, that it must be designed to be safe.

Contemporary storm drains are designed to conform with design requirements that take bicycles into account. However, there are still old drains in existence which, like unexploded military ordinance, create a potential hazard for anyone passing over them. In addition, even properly designed storm drains can pose a hazard if the drain surface is installed below the pavement surface of the road.

One of the techniques used by street departments to repair a crumbling roadway is to install a new asphalt surface. A road surfacing machine removes the crumbling surface section of the old road and then new blacktop is installed. Sometimes this process occurs over and over again so that the surface of the roadway rises slightly with each application. However, when this technique is used, the storm drains located at the edge of the roadway must be raised to be flush with the new surface of the roadway. If the storm drain is left recessed at the old roadway level, it creates a hazard for bicyclists proceeding along the edge of the road. Storm drains and manhole covers in the main traveled portion of the roadway are typically raised with some sort of collar device to avoid a traffic hazard; but some storm drains at the edge of the roadway are not given the same careful treatment. It is important that roadways be designed, and upgraded, to take both motorized and non-motorized users into account, and the storm drain statute mandates that all drains in any portion of the roadway over which bicyclists may legally travel must be safe.

What To Do To Report A Violation

If you know of a storm drain that presents a potential hazard in violation of the statute, call or write a letter to your local road maintenance department. Sometimes merely advising the maintenance department of their civic responsibility or the requirements of the statute may not be enough to make things happen. In these times fear of “liability” or a “potential lawsuit” is often used as an excuse for denying access to users of public and private facilities (“I’m sorry but we cannot let you go in there because if someone got hurt then we might get sued.”). You can use the potential lawsuit phobia to actually make something good happen by letting maintenance departments that if someone was hurt by a dangerous storm drain a lawyer could “cause trouble” for the city or county and then the taxpayers many have to pay for an injury. Make sure you send a copy of the letter to County Counsel or City Attorney’s Office to provide additional notice of the dangerous condition.

Regular commuters along stretches of road containing dangerous storm drains have probably learned over time to avoid hazards on their ride. However, the riders who are most likely going to be hurt are more occasional users. It is important for the benefit of other riders who may be riding over unfamiliar terrain or at night that regular riders of particular routes advocate for safe conditions. A sample letter advising of a drain problem is copied below. Note that the letter attempts to discuss the importance of the thoroughfare for bicyclists. The tone should not be threatening or whiny, but authoritative.

Re: Storm Grate In Front of St. Vincent Hospital

Dear Sir/Madam:

This letter is to advise you and to provide notice of a dangerous condition existing which violates the Oregon Revised Statutes.


As you know, SW Barnes Road is a major bicycle commuter thoroughfare for persons heading east and west alongside the Sunset Highway. Bicycle traffic in front of St. Vincent Hospital is fairly heavy and the road is quite narrow with a small paved shoulder. Because of the proximity to the Catlin Gabel School, St. Vincent Hospital, the Sunset Transit Center, and The Oregon College of Arts & Crafts, the roadway heavily used by bicyclists.

Unfortunately, there are at least two storm drains on the north side of SW Barnes Road directly in front of St. Vincent Hospital that appear to be recessed below the level of the asphalt by as much as one and a half to two inches. These storm drains are a hazard to bicyclists and are in violation of the law.

ORS 810.150 requires that grates and drains be engineered such that bicycles can pass safely over them. These storm drains clearly do not meet this test and should be re-engineered to bring the drain up to the level of the roadway surface.

If a bicyclist were to be injured as a result of colliding with one of these storm drains, it would likely result in a significant claim against the county.

Please provide me with your position in regard to this problem at your earliest opportunity. For your information, I am providing a copy of this letter to the office of the Washington County Counsel for their review.”

Agencies in charge of maintenance for areas with dangerous hazards need to hear from bicyclists. Conditions are allowed to exist on roadway shoulders that would never be tolerated on the main section of the roadway. Often these dangers exist because maintenance departments fail to realize that roadway shoulders are heavily used by bicyclists. While the wheel you save may not be your own, it is very satisfying to see roadway improvements resulting from your good efforts.
