说明

The stormwater drains on the Olive Ave repaving were not built to the cities own engineering specifications. This opens the city to liability, since they instead installed a more dangerous kind known as "bike killers", since they can cause bicycle tires to get caught, injuring or killing people bicycling.
The city design specification calls for a safer style, but unfortunately were not used: http://wpb.org/wp-content/uploads/sites/7/2013/02/ST-5.pdf
