The flooding that has moved through Indiana over the past week has been historic — record river crests, thousands of evacuations, and losses no community wants to measure in lives instead of just property damage. Our thoughts are with everyone across the state who has been displaced or affected, including residents in communities near our own backyard here in Carmel.
Storms like this also force a harder question for anyone who operates rental housing: when the next one comes, how ready is your community actually going to be?
For multifamily and build-to-rent operators, flood events like this aren’t just a maintenance issue. They’re a resident-safety issue, an asset-protection issue, and increasingly, an operational differentiator. Here’s what property managers should be thinking about on both sides of the storm — prevention before it hits, and response once it does.
Prevention: The Work That Happens Long Before the Forecast
Most flood damage to rental communities isn’t caused by the storm itself — it’s caused by drainage and maintenance issues the storm exposes. A few areas deserve regular attention, not just a once-a-year check:
Grading and site drainage. Water needs somewhere to go that isn’t a resident’s front door. Walk the property after any heavy rain and look for pooling near foundations, garages, or ground-floor units — that’s often the first sign of a grading problem building toward a bigger one.
Gutters, downspouts, and storm drains. Clogged gutters and blocked storm drains turn a normal rain event into localized flooding fast. This is especially true for BTR communities with more roofline and more individual downspouts per acre than a typical garden-style multifamily property.
Sump pumps and backflow valves. Any unit with a basement or below-grade utility space needs a sump pump that’s actually been tested — not just installed. Backflow valves on sewer lines are cheap insurance against sewage backup during high-water events, and they’re often overlooked until it’s too late.
Window wells, seals, and foundation cracks. Small entry points become big problems under sustained rainfall. These are quick items for a maintenance walk-through, not a full inspection.
Vehicle and mechanical exposure. HVAC condenser units, electrical panels, and parking areas in flood-prone zones deserve a second look at placement and protection, particularly for garden-style and BTR sites where units sit closer to grade.
Alerts: Getting Ahead of the Storm, Not Behind It
Prevention only goes so far without a way to act before water is already in a unit. A real alert system for a rental community means:
- Weather monitoring tied to action, not just awareness. Knowing a flood watch is issued matters less than knowing who does what when it is. Staff should have a clear trigger point — a specific rainfall forecast or river level — that kicks off a pre-storm checklist.
- Resident communication that goes out before the water rises. A text or email alert with specific guidance (move vehicles, avoid parking garages, know your evacuation route) gives residents a real head start, not just an FYI after the fact.
- A maintenance and vendor call tree that’s tested, not theoretical. When storms are regional, plumbers and restoration vendors get booked fast. Communities with existing vendor relationships and a clear internal escalation plan get help faster than the ones scrambling to find a vendor mid-crisis.
- Documentation habits before damage happens. Photos and condition records of common areas, parking structures, and ground-floor units make insurance claims and resident communication faster and cleaner after the fact.
Why This Matters More for BTR Specifically
Build-to-rent communities carry some flood-preparedness considerations that differ from traditional multifamily. More units sit at or near grade. Private yards and garages — a major BTR amenity and leasing driver — are also more directly exposed to standing water and drainage failure than a mid-rise unit above street level. And with residents often more invested in a house-like living experience, how a community responds to a flood event has an outsized impact on renewal decisions and word-of-mouth reputation in the submarket.
Operational discipline is already the difference between BTR communities that are thriving and those that are struggling in today’s environment. Storm readiness is one more place where that discipline shows up — quietly, until the day it doesn’t.
The Real Takeaway
Flood events like the one Indiana just experienced aren’t predictable in timing, but the response to them can be. Communities that treat drainage maintenance, alert systems, and vendor readiness as ongoing operational infrastructure — not a once-a-year checklist — are the ones that protect residents faster, protect assets better, and come out the other side with less damage and more trust.
That’s the standard we hold ourselves to across every community we manage.
