STORMWATER
Did you know?
From anywhere in Grand Rapids, it
takes just 15 to 30 minutes for
stormwater to get to a water body.
The following slides show the Six Minimum
Control Measures needed to keep stormwater,
and our lakes and rivers, clean.
Six Minimum Control
Measures
1. Public Education and Outreach
2. Public Participation/Involvement
3. Illicit Discharge Detection and
Elimination
4. Construction Site Runoff Control
5. Post-Construction Runoff Control
6. Pollution Prevention/Good
Housekeeping.
Public Education and Outreach
Inform individuals and households on ways to reduce
stormwater pollution, such as:
1. Washing cars on their lawns, instead of on pavement that drains to
the storm system.
2. Spreading the word that most stormwater catch basins drain
directly to the river.
3. Reducing stormwater runoff from their property by installing rain
barrels and rain gardens.
4. Notifying the City stormwater department if someone is seen
discharging pollutants to the stormwater system.
Public Participation / Involvement
Engaging and involving stakeholders in the Lower Grand
River Watershed:
1. Mayors’ Grand River Cleanup http://www.grandrivercleanup.com/
2. Rain Barrel Workshops - https://wmeac.org/water/rainbarrel-workshops/
3. Participation with a local watershed group (Lower Grand
Rapids Organization of Watersheds, Plaster Creek Stewards)
Illicit Discharge Detection and Elimination
Identifying and reporting illegal discharges to
the stormwater system.
Report It Don’t Ignore It
Report all suspect discharges to stormwater –
(616) 456-3057 or stormwater@grcity.us
Construction Site Runoff
Control
Keeping soils from running into the streets and/or
catch basins during construction
Report It Don’t Ignore It
Report all suspect discharges to stormwater – (616)
456-3057 or stormwater@grcity.us
Post-Construction Runoff Control
Developers and property owners must address
stormwater runoff after construction is completed.
1. Storage is to be provided to make preconstruction runoff equal post-construction
runnoff.
2. Water quality measures are to be installed to keep
pollutants out of the City stormwater system.
Pollution Prevention / Good Housekeeping
Keeping the City’s facilities clean to prevent
pollutants from discharging to the stormwater.
• Street Sweeping
• Catch Basin Cleanout
• Spill Prevention and Cleanup
