What are the types of stormwater runoff control measures?
-Pipe slope drain
-Runoff diversion measures
-Temporary stream crossing
-Construction de-watering
-Buffers and flow control
What is a pipe slope drain?
A pipe that runs down the side of a slope is used when water must flow
downslope without causing erosion, especially before slope has been
stabilized or before permanent drainage structures are installed, they
can be permanent or temporary
What is the common solution for if the pipe separates?
Reconnect pipe sections, securely anchor and stabilize pipe into soil,
and ensure pipe connections are watertight
What is the common solution for if the pipe outlet erodes?
Repair the damage and stabilize the outlet with a flared end section, rip-
rap, TRM, or velocity dissipation device, and if necessary, reduce flows
being discharges
What is the common solution for if the pipe becomes clogged?
Flush out the pipe, place a screen or grate at the inlet to capture trash
and large particles
What are a few Runoff Diversion Measures?
-Diversion dikes
-Berms
-Temporary silt ditches
-Swales
What is a diversion dike?
A buildup of compacted soil that forms a "wall" created at the crest of a
hill
