Storm drain stencils are templates or patterns used to mark storm drains on streets and other surfaces. These stencils typically feature symbols or messages to raise awareness about the purpose of storm drains and to convey important environmental messages. Here's a description of storm drain stencils: Design: Storm drain stencils commonly feature a combination of text and symbols. The symbols often include images related to water, aquatic life, or environmental awareness. The text may include messages such as "No Dumping - Drains to Waterways" or other warnings about the connection between storm drains and local water bodies. Material: Storm drain stencils are usually made of durable materials like plastic or heavy-duty cardboard, which allows them to withstand outdoor conditions. Size: The size of storm drain stencils can vary, but they are typically designed to be easily visible. The size ensures that the markings are noticeable to pedestrians and motorists. Application: These stencils are used in combination with paint to mark storm drains. They are placed directly over the storm drain opening, and paint is applied through the openings in the stencil onto the surface, creating the desired message or symbol.
