Marion sits on high ground — yet 5,000 homes flooded in July 1987 when storm sewers failed. Integrity Water Damage Restoration Ohio offers 24/7 emergency extraction. Call (614) 956-3233.
Water Emergency Right Now?
Do these five things first — then let us take it from there.
- Stay safe first. Don't walk through standing water if the power may be on — and never touch submerged outlets, panels, or appliances.
- Stop the source if you can. Shut the main water valve for a burst pipe or appliance leak. For storm flooding, focus on safety, not the water.
- Call (614) 956-3233 now. Our dispatchers answer 24/7 and can talk you through the next steps while a crew rolls.
- Move what matters. Lift rugs, electronics, and furniture legs out of the water if it's safe to do so — every inch helps.
- Don't wait on drying. Mold can start within 24–48 hours. Fast professional drying is the difference between a cleanup and a rebuild.
01High Ground That Floods: Marion's Strange Water Problem
Marion's flood story starts with a paradox, stated plainly in a U.S. Geological Survey flood report: the city sits "on high ground between the Scioto and Olentangy Rivers." You would think that means safety. It doesn't — because Marion's signature flood disaster didn't come from either river. It came from the streets themselves.
On July 1–2, 1987, overloaded storm sewers and ditches — unable to handle surface runoff — flooded most city streets and pushed water into basements and lower floors across Marion. About 5,000 homes sustained some flood damage; roughly 500 were extensively damaged. Documented damage clusters included businesses and an apartment complex north of Harding Way at North Portland Way, about half a dozen homes along Olentangy Court, and Charles Street near East Street — where two auto dealerships lost 55–60 new cars, roughly $500,000 in inventory. Local officials estimated losses at $1–2 million; the Marion County Disaster Office put the figure at several million. (USGS Open-File Report 89-376.)
That's the thing about Marion: the water doesn't arrive as a river over its banks. It arrives as runoff with nowhere to go — and it goes into basements. Integrity Water Damage Restoration Ohio provides 24/7 emergency water damage restoration across Marion and Marion County: extraction, sewage cleanup, structural drying, and mold prevention. Call (614) 956-3233.
02July 1–2, 1987: Anatomy of a Storm-Sewer Flood
The 1987 flood is worth understanding in detail, because its mechanism is still Marion's primary threat:
- The trigger: intense rainfall overwhelming storm sewers and drainage ditches — not river overflow. The USGS report is explicit: flooding was "principally to basements and lower floors."
- The scale: most city streets flooded; ~5,000 homes with some damage, ~500 extensively damaged.
- The hotspots: North Portland Way north of Harding Way (businesses and an apartment complex), Olentangy Court, Charles Street near East Street (the dealership losses).
- The cost: $1–2 million per local officials, several million per the county Disaster Office — in 1987 dollars.
Storm-sewer overload is a different disaster from river flooding, and it demands a different kind of readiness. There's no river gauge to watch, no upstream dam release to track — just rainfall intensity versus pipe capacity. When the pipes lose, water enters through the lowest available opening: basement windows, foundation joints, floor drains. If your Marion basement has flooded before, it will flood again under the same conditions unless something changed — a backwater valve, a sump system with battery backup, regraded drainage. Call (614) 956-3233 and we'll assess your basement's defenses during your restoration visit.
03Engineered Away: The Reservoir, the Dike, and the End of River Flooding
Marion's relationship with river flooding is genuinely historical — and that's the point. The Marion County Record's flood retrospective documents significant floods in 1941 and especially 1951, when flooding was a way of life in parts of the city. The March 1913 statewide catastrophe dumped 10.5 inches of rain at Marion (Akron Beacon Journal). But the Record notes the turning point precisely: "Marion was not rendered safe from flooding until after Marion Reservoir was completed in 1968 and a dike and diversion channel were completed in 1977" — and "no areal flooding has occurred within the city since the dike's completion."
So the rivers are handled. The Scioto and Olentangy headwaters that bracket the city are managed by the reservoir and the dike system. What remains — what the 1987 flood proved and what every heavy summer cloudburst since has confirmed — is the storm-sewer system: aging clay-tile infrastructure, flat lake-plain terrain that sheds water fast, and small ditches that are the city's drainage spine and its failure point. NWS was still issuing urban and small-stream flood warnings for Marion County in July 1989. The river won't get you. The runoff might.
04Older Basements and the Harding Way Commercial Corridor
Marion is an industrial city with older housing stock — and older basements are where storm-sewer overload does its worst work:
- Aging clay-tile storm infrastructure — older pipes with root intrusion, joint failures, and reduced capacity under the streets of established neighborhoods.
- Basement seepage patterns — saturated ground plus hydrostatic pressure pushing water through floor-wall joints and foundation cracks, even when the street looks fine.
- Sewer surcharge — when storm systems overload, sewage can back up through floor drains. That's Category 3 black water: stay out, don't run fans, call (614) 956-3233 immediately.
- Commercial exposure — the Harding Way/North Portland Way corridor, hit in 1987, concentrates businesses and apartment complexes where a single storm-sewer failure becomes a multi-tenant loss. Integrity Water Damage Restoration Ohio handles commercial water damage at scale: multi-unit extraction, phased drying, and documentation that keeps business-interruption claims clean.
Winter adds freeze–thaw burst pipes in older Marion homes — uninsulated plumbing in crawlspaces and exterior walls. Year-round, the rule is the same: fast extraction and verified drying beat everything. Mold can begin within 24–48 hours. Call (614) 956-3233 any time.
More Than Water Removal
Water is only the first problem. Here's what we actually fix when we walk through your door.
Structural Damage
Standing water weakens framing, subfloors, and foundations. Fast extraction stops a small leak from becoming a structural repair.
Mold Growth
Mold can colonize damp drywall within 48 hours. We dry to verified moisture standards and treat surfaces to prevent regrowth.
Health Risks
Sewage backups and long-standing water carry bacteria and contaminants. We clean and sanitize until the space is safe again.
Lingering Odors
A musty smell means moisture is still hiding somewhere. We find the source, dry it completely, and deodorize — never just mask it.
Ruined Floors & Walls
Buckled hardwood, swollen drywall, peeling paint. We remove what can't be saved and rebuild what matters, start to finish.
Insurance Stress
Claims stall on thin documentation. We photograph everything, log moisture readings daily, and deliver adjuster-ready reports.

The USGS puts it plainly: Marion is "on high ground between the Scioto and Olentangy Rivers," and its signature flood (July 1987, ~5,000 homes damaged) was caused by overloaded storm sewers and ditches, not river overflow. Runoff with nowhere to go enters through basements — high ground doesn't help when the pipes are the problem.
The 1968 Marion Reservoir and the 1977 dike and diversion channel ended areal river flooding — no river flooding within the city since. But they don't manage storm-sewer overload, which is what flooded 5,000 Marion homes in 1987 and remains the primary threat.
On July 1–2, 1987, intense rain overwhelmed Marion's storm sewers and ditches. Most city streets flooded; about 5,000 homes took some damage and ~500 were extensively damaged. Hard-hit spots included North Portland Way, Olentangy Court, and Charles Street — where two dealerships lost 55–60 new cars (~$500,000). Losses ran to several million dollars.
Standard policies typically exclude sewer backup — you need a water backup endorsement. Rising river or creek water needs a separate flood policy. Photograph everything after an event and call (614) 956-3233 for claim-ready documentation.
Yes — the Harding Way/North Portland corridor's businesses and apartment complexes are exactly the multi-unit losses we handle: rapid extraction, phased drying, and documentation for business-interruption claims. Call (614) 956-3233 24/7.
