Dear (Insert Mayor’s Name and Safety Director’s Name):

My name is (insert your name) and I am an avid bicyclist in the (insert location name, and mention if you’re a member of any bike clubs/organizations such as Bike Cleveland.

I am concerned about the dangers of these parallel stormwater grates along (street name) in (location name). There are approximately (enter quantity) dangerous drainage grates at (enter cross streets). Due to the horizontal bar placements, a bicycle tire can easily become stuck in the grate causing serious risk and injuries to cyclists.

Please refer to this article, “Parallel stormwater grates can endanger cyclists. If you see one, say something” for the dangers posed to bicycles of parallel stormwater grates.

There are a number of different grate styles; the ones with smaller grids and narrower openings are better for bikes. Please remember that the city would likely have to do drainage analysis to make sure that the replacement grates provide the right amount of flow (basically, permeability) to maintain appropriate drainage.

The American Association of State Highway and Transportation Officials warns that drainage grates with openings running parallel to the curb can cause narrow bicycle wheels to drop into the gaps and cause a severe crash. Care must be taken to ensure drainage grates are bicycle‐safe, with openings small enough to prevent a bicycle wheel from falling into the slots of the grate.[1]

The Federal Highway Administration currently recommends a few different grate designs to minimize risks for bicyclists. Bars can be perpendicular to the direction of travel or, when the bars follow the direction of travel, there can be crossbars up to six inches apart to keep wheels from getting caught. There are also designs with small shapes such as a hexagon that achieve the same safety effect.[2]

The Ohio Department of Transportation states: Shared lanes are the most common bicycle accommodations since bicycles may operate on all roadways except were prohibited by ORC Section 4511.051- .[3]

Many cities in Ohio, such as Cleveland, Columbus, Cincinnati and Westlake are changing their stormwater grates to reduce the risk to bicyclists on the road. We encourage (location name) to join the trend and make the location more bicycle friendly.
