Storm Drain Stewards
When it rains, we clear the drains.
It's the fifteen blocks looking out for each other the morning a storm rolls in. Keep an eye on a corner or two near you if you like — but the real work is quick and shared: whoever's around checks the board, clears what's still amber, and marks it done, so no corner floods because everyone assumed someone else had it.
A clogged drain isn't just a homeowner's problem.
When a catch basin backs up, the water climbs the curb and sits — and everyone on the block pays for it, whether they own, rent, drive, or just walk to the train.
Homes — every floor
Water finds the lowest basement on the block, whether you own or rent.
Parked cars
A curbside pond floods the engines and interiors of cars up and down the block.
Getting around on foot
No one should have to step into moving traffic to skirt a lake at the corner.
Strollers & wheelchairs
A flooded crossing strands anyone on wheels right where the curb ramp is.
Dogs on the walk
Storm runoff carries road salt, oil, and worse past every pet on the block.
The storm board.
17of 41 corners clear
Amber grates haven't been checked yet this storm — tap one and mark it cleared so no one doubles up. Green is done; red means a corner's flooding and needs clearing right now. Whoever's around, grab an amber one to check — or a red one to go help clear.

The whole job, in four lines
It really is this small.
- ① Watch the forecast for heavy rain.
- ② Rake the grate clear beforehand, from the sidewalk.
- ③ Bag the debris and set it out with your trash.
- ④ If it's jammed, call 311 and tell the chat. Done.
Join the crew
Before the storm
- Rake leaves and litter off the grate from the sidewalk.
- Bag it and set it out with your trash — don't push it into the street.
- Drop a 👍 in the chat so the block knows it's clear.
During & after — safety first
- Stay on the sidewalk. Never step into moving water or lift a grate.
- No lightning, no high wind — it can wait.
- Jammed or flooding anyway? Report to 311 and flag it in the chat.
Missing from the map?
Know a drain that always backs up?
Send us the corner. We'll add it to the map so the crew keeps an eye on it — especially the ones that flood first.
