Flooding in Walker, Michigan isn’t one-size-fits-all, and that misunderstanding can lead to costly surprises. We sit down with City Engineer Scott Conners to break down the two flood problems residents actually see: sudden flash flooding that overwhelms streets and catch basins during high-intensity rain, and slower Grand River flooding that can be forecast days in advance as water moves through the watershed.

We get specific about what the City of Walker does for flood mitigation and stormwater management, from spring inspections of the Turner Avenue flood wall to real-time decision-making when storms are on the way. Scott explains why a “100-year storm” isn’t a perfect 24-hour rain event in real life, and how bursts like two inches in two hours can push storm sewers past capacity. You’ll also hear how Public Works crews prepare by clearing catch basin grates, removing debris, and opening clogged pipes, plus how National Weather Service river forecasts guide warnings to businesses that may need to lift equipment before water reaches the road.

We also cover what you can do at home to reduce localized flooding risk: keep ditches and drainage paths clear, avoid blowing leaves into streets, and don’t pile sticks where runoff can carry them into pipes. We talk about how new development is required to use detention ponds and infiltration to control runoff, and why flood insurance through the National Flood Insurance Program can still matter even outside a mapped floodplain.

SPEAKER_01 (00:07):
Welcome to Maiden Walker, a podcast that connects
you to the people, the stories,and the ideas shaping our
community.
From local innovators toeveryday change makers, we're
diving deep into what makesWalker a great place to live,
work, and grow.
Here's your host, NicoleDiDonato.

SPEAKER_02 (00:26):
Flooding in Walker isn't one size fits all.
Sometimes we get those quick,heavy downpours.
Other times it's a little moregradual and the Grand River
rises.
But that's why we have CityEngineer Scott Connors to join
us for this episode to talkabout flooding, what the city's
done to mitigate it, the typeswe see around the area, and what
residents can do to kind of helpthemselves.
Thank you, Scott, for beinghere.

(00:47):
Welcome.
Yeah, perfect day to talk aboutthis.
Looking a little overcast, butuh tell us the two types of
flooding that we generally seearound the city every year.

SPEAKER_00 (00:55):
Well, I think the big complaints that we get are
are the first off is the flashflooding that we see, like in a
neighborhood, if the streetsoverwhelmed and the water gets
up over the catch basins in theroad, uh, slows down vehicles.
Um, as that's just as the nameuh suggests.
It's flashy.
It happens right away, itusually subsides in a few
minutes.
Um, the other kind of floodingthat we get along the Grand
River, we can really forecastand see coming.

(01:17):
And it's a result of largerainfalls in the Grand River
watershed.
If you look upstream, you've gotLansing, uh Portland, further up
at the very headwaters, theGrand River is Jackson.
So if you get a big storm outthere, a lot of times we don't
see the impacts to that for twoor three or even four days.

SPEAKER_02 (01:34):
Got it.
Okay.
So then what does the city do tokind of uh prepare for that type
of?

SPEAKER_00 (01:38):
Well, we actually got a flood wall along Turner
Avenue that um we watch uh it'sa it's an integrated fret flood
wall with the city Grand Rapidssystem.
And so we keep track of that, wedo inspections on that in the
spring.
Uh we go out and check and makesure all the outlets are working
uh and and are effective.
Um but along Turner and alongNorth Park Street, those are
some of the areas that we seeboth the flashy floods and the

(02:01):
long-term uh more uh late risingGrand Rapids flood or Grand
River floods.

SPEAKER_02 (02:06):
Yeah.
And uh earlier this season um wesaw uh just a heavy downpour,
maybe some spots that uh floodedin Walker that we don't
typically see year after year.
So these 100-year floods kind ofchanging, it seems like,
changing in terms.

SPEAKER_00 (02:20):
It is, and there's a lot of debate about that.
Uh in Grant in the Grand Rapidsarea, we look at a 24-hour,
100-year storm as uh having sixinches of rain, six point two
five inches of rain over twentyfour hours.
But that's evenly distributed ina scientific and theoretical
world.
We've never gotten a perfecthundred-year storm.
It's impossible.
Uh we'll end up with uh uhflashier events, uh sometimes a

(02:43):
long sustained event, but neverfor 24 hours straight.
So the storms that we had a fewweeks ago, uh, we got about two
inches of rain in two hours,which is a very high intensity.
And on top of that, we ended upwith about three total inches of
rain, but it was spread probablyover four or five hours
throughout the evening.
But those two inches are sointense, it overwhelms the storm
sewer systems in the streets,some of the backyard ditches,

(03:05):
and so then we see thatlocalized flooding.

SPEAKER_02 (03:07):
Yeah, and many people may not realize, but when
there are these these types ofstorms, you and our public works
crews, you guys are out drivingaround.
It doesn't matter what time ofnight, 2 a.m., whenever it is,
you're out kind of keeping aneye on these things in the dark.

SPEAKER_00 (03:19):
Yeah, and that's a big part of our job too, is to
forecast that.
And in this last event, I wasreally proud of our guys in
Public Works.
They could see this coming.
And uh one of our senior membersback there, Pat Poss, was able
to kind of pull the trigger toget all of our crews out the day
before to clean off catch basingrates, to get rid of sticks and
leaves, uh, to clean out uhpipes that may have been plugged
and basically open the system upso we didn't see uh any

(03:42):
impediments that would causeeven more localized flooding.

SPEAKER_02 (03:45):
Sure, sure.
And what other types of toolsand such do you use to for
monitoring this type offlooding?

SPEAKER_00 (03:50):
The National Weather Uh Service has some great tools
that we look at uh to look atthe river levels, and and we use
that uh extensively inforecasting what we may have
coming.
And a few years back we had alot of flooding uh that was
Grand River related.
Um you can monitor that, you cansee it again two or three or
four days in advance, and uh theNational Weather Service
provides predicted levels.

(04:11):
And um, so we'll look at that,and if we see a situation that
might uh uh impact some of ourindustrial businesses perhaps on
on Turner, what we've donepreviously is we've gone out and
told them in advance, hey, it'sit's time to get your expensive
equipment off the floor in theseareas.
Um, you may want to put stuff upon blocks, uh, you may want to
you know move some things aroundbecause we're liable to see uh

(04:33):
upwards of a foot or two ofwater in the road and in some of
those businesses that have beenthere for a long time, even in
their uh the floors of theirmanufacturing facilities.

SPEAKER_02 (04:41):
Okay.
So we were seeing what the withthe city does and that yeah, um
being proactive and doing theoutreach to businesses and such.
What can residents typically doto uh help themselves and reduce
that risk?

SPEAKER_00 (04:52):
I think a really big part of that is to keep track of
the drainage that's on yourproperty.
So if you've got uh storm sewerin your backyard or catch basins
where the surface water goes, oreven a ditch, um, make sure that
you keep those things clean.
And so if they need to be mowed,you should you know do that on a
regular basis.
If you've got uh leaves that youwant to blow or sticks that you
want to put up in a pile, don'tput them back there where

(05:14):
they're gonna wash in and plugup a pipe or a drain, because
that just makes the whole systemuh suffer at that point.
And everybody upstream has todeal with higher water until
that plug can be uh removed.

SPEAKER_02 (05:27):
Maybe a misconception too that we hear
is whenever there's a newdevelopment going on in Walker,
how will that impact floodingother folks their properties,
things like that?

SPEAKER_00 (05:36):
Aaron Powell Yeah, I think if you go back into uh
development that's post-WorldWar II, um we would just throw
up developments and not thinkabout the stormwater.
But every time you take down aforested area and put in a paved
and rooftop area, it changes howthe water gets back into the
ground.
And so we see less uhinfiltration.
And with that, you have moreoutlet, more uh outflow from

(05:57):
those sites.
Uh we've learned in the 70s and80s and especially now that it's
important for us to put incontrols to help mitigate that.
So now we put in things likedetention ponds.
We look for ways that we can putwater back into the ground
through infiltration.
So now we have to look at thekind of soils that are on a site
when it develops.
Um but I guess overall we've gotan ordinance here in Walker and

(06:18):
all through Kent County and ourneighboring counties that's a
very comprehensive set of rulesso that when a new development
comes in, we can make thosemitigations.
And oftentimes we can even takethe peak off the existing storms
and make things just a littlebit better.

SPEAKER_02 (06:31):
Well, good information to know.
But when it comes to floodinsurance, is that something
that our Walker residents areactually eligible to try?
They are.

SPEAKER_00 (06:38):
Okay.
And we get a lot of questionsabout that.
So we are part of the NationalFlood Insurance Program, NFIP,
which is a federal program thatallows uh insurance agents to
then sell flood protection toour residents.
Uh if we're not a part of thatprogram, then the insurance
agents aren't obligated toprovide that insurance.
So even if you're outside of afloodplain, if you're worried
about localized flooding, youcan still go get that flood

(07:01):
insurance and have protectionsfor your basement, for your
water heaters and furnaces andcritical items that wouldn't be
available if we weren'tfollowing those federal
guidelines as a city.

SPEAKER_02 (07:12):
And um are the as far as uh that flood insurance
or certain areas where there'sflooding, is there more specific
parts in Walker that is moreprone to it?
If or if people move into thatarea, they know that they are
part of a floodplain?

SPEAKER_00 (07:23):
Aaron Powell Yeah, I think a lot of the older
neighborhoods, and again thepost-World War II neighborhoods
where there was no thought orcare given about stormwater, it
was just send it downstream asquick as you can and and uh and
get back on with your life.
Um, those areas uh are are alittle bit more troublesome.
So the older neighborhoods, thenewer neighborhoods
traditionally have uh stormsource systems that are sized

(07:43):
appropriately.
We have detention, uh, we haveuh multiple uh you know
redundancy in our catch basinsystem.
So if one plugs, it's gonna flowinto another one without
damaging a home.
And then we also take great carewith our building department to
make sure that homes are builtat the proper elevation.
Uh in the past, a lot of timessomebody might look at a house
and say, Um, I'd like to have awalkout basement there because

(08:05):
it's worth more money and morefun for me.
Um, but then they lower thatelevation and they get it too
far down where maybe it issubject to uh to flooding.

SPEAKER_02 (08:14):
So when you are meeting with developers too and
looking at because we we do havesome new neighborhoods and
developments that will be goingup, especially in the next 10
years, even or sooner than that,what are some of the
considerations that you guystalk through?
Yeah.

SPEAKER_00 (08:24):
Well, I think we take a look at a lot of
different things.
We look at the uh the KentCounty Drain Commissioners uh
system because there's a lot ofareas that are served by uh
larger drains that are part ofKent County Drain Association or
Drain Commission.
Um we also take a look at uhprevious uh uh issues where we
had localized flooding, and wetry to mitigate that as best we

(08:44):
can.
So if somebody wants to go inand build in an area that we
know has had flooding, we makesure that they compensate for
any kind of flood storage thatthey'll be eliminating with
their project.
So oftentimes they have to buildmuch more detention or a
floodplain kind of an area wherewater uh that sat before can sit
again, in addition to all theadditional water that they'll be
creating.
Aaron Powell Yeah.

SPEAKER_02 (09:04):
Very good information to know that these
precautions are being um youknow put into place and uh taken
by everyone involved.
So, what is uh you know a bigtakeaway that residents can take
away from this podcast and theinformation that you're giving
about the flooding?

SPEAKER_00 (09:16):
Aaron Powell Well, I think the the big takeaway maybe
is that everybody can chip inand everybody can take a role in
this.
Don't push your leaves out intothe street.
Uh don't push the leaves andsticks into your backyard where
there might be some drainagethat goes from side to side or
into a ditch.
Um and then um just kind ofwatch the weather.
I mean, it that's what we do.
I mean, we have to keep a closeeye on that.
There's nights where uh astonight, as we look out the

(09:37):
window and see some storm,stormy weather and potential
damage, we have to uh be awareof that and and and cognizant of
it so that we can plan ahead andtake some mitigation if we can
by keeping things uh open andunobstructed.

unknown (09:50):
Yeah.

SPEAKER_02 (09:50):
Well, really appreciate the conversation, the
great information as well.
