Inlets
Inlets are typically located at:
- Sag points in the gutter grade
- immediately upgrade of median breaks, crosswalks

Best management practice. State of the art methods or techniques used to manage the quantity and improve the quality of wet weather flow. BMPs include: source, conveyance and end-of-pipe controls.
The portion of water precipitated onto a catchment area, which then flows as surface discharge from the catchment area past a specified point.
Water from rain, snow melt, or irrigation that flows over the land surface.
Soil, sand and minerals washed from land into water, usually after rain. They pile up in reservoirs, rivers and harbors, destroying fish-nesting areas and holes of water animals and cloud the water so that needed sunlight might not reach aquatic plans. Careless farming, mining and building activities will expose sediment materials, allowing them to be washed off the land after rainfalls.
A shallow excavated surface depression containing prepared filter media, mulch, and planted with selected vegetation.
Ground depression acting as a flow control and water treatment structure, that is normally dry.
The portion of water precipitated onto a catchment area, which then flows as surface discharge from the catchment area past a specified point.
Water from rain, snow melt, or irrigation that flows over the land surface.
A mixture of mineral aggregates bound with bituminous materials, used in the construction and maintenance of paved surfaces.
A bioretention BMP featuring an impermeable liner and underdrain that prevents infiltration of runoff into the underlying native soil; provides sedimentation and filtration of urban runoff as it passes through the mulch layer, engineered filter media and vegetation root zone.
A bioretention cell that features an impermeable liner that collects and treats stormwater through sedimentation and filtration only (i.e., no infiltration).
A shallow constructed channel, often grass-lined, which is used as an alternative to curb and channel, or as a pretreatment to other measures. Swales are generally characterized by a broad top width to depth ratio and gentle grades.
Includes the protection of soil from dislocation by water, wind or other agents.
Linear bioretention cell designed to convey, treat and attenuate stormwater runoff. The engineered filter media soil mixture and vegetation slows the runoff water to allow sedimentation, filtration through the root zone, evapotranspiration, and infiltration into the underlying native soil.
