Advice to Those Considering Living Near Water

7/29/2026 – The allure of living near water is both primal and spiritual. Water is soothing, refreshing, sustaining, beautiful, comforting and necessary. For much of human history, people HAD to live near water. Rivers became cradles of civilization.

But occasionally, river flooding also brings destruction. And when modern engineering and infrastructure made it possible to live farther from rivers, most moved to higher ground away from danger.

Empty townhomes near San Jacinto West Fork stand a mute witness to the power of nature after Harvey.

Still, for some people, living near water is worth the risk and uncertainty … so much so that they often pay a premium for homes with higher flood risk. Whether that premium is worthwhile depends on your disposable income and risk tolerance. Go into a major purchase with eyes wide open. Here are several things to consider.

Understanding Flood Risk is Crucial

If I were advising a close friend buying a home near water in the Houston area, I would say this:

“Buy for the water view only if you fully understand what comes with it.”

Waterfront homes — whether on a lake, river, creek, bayou, or even a retention pond — often command a price premium. But in Houston, that premium can come with higher flood risk, higher insurance costs, more difficult resale, and greater uncertainty as flood maps and rainfall assumptions evolve.

Recent draft FEMA flood maps, for example, significantly expand mapped floodplains in Harris County. Meanwhile, many other surrounding counties, eager to expand their tax bases, have not updated flood maps in decades.

10 Key Considerations

Here are several topics I would explore before making an offer.

1. Has the structure ever flooded?

This may be the single most important question. Don’t just ask the seller.

Also:

  • Talk with neighbors.
  • Check county flood records if available.
  • Look for old news photos.
  • Search social media after Harvey, Tax Day, Memorial Day, Imelda, and other major storms.
  • Ask whether water entered the structure—not merely the yard.

A home that stayed dry during Harvey generally deserves a closer look than one that flooded repeatedly.

2. Is the home near the water or above the water?

Those are very different.

A house perched 40 feet above a lake may have spectacular views with little flood risk.

A house six feet above a bayou may have the same view — but vastly different risk.

In Houston’s relatively flat terrain, the elevation of the first finished floor relative to expected flood levels matters far more than the horizontal distance to the water.

3. How high is the slab?

Ask for the:

Two houses across the street from one another may differ by only 18 inches in slab elevation — but that can dramatically affect both flood risk and insurance premiums. We saw that in the Elm Grove flooding in 2019.

4. Don’t stop with FEMA maps.

FEMA maps are useful. But they are not the complete story.

In Harris County during Harvey, more homes flooded outside the mapped 100-year floodplain than flooded inside it (Page 13).

Maps also become outdated as:

FEMA itself notes that mapped flood zones are only one tool for understanding risk. And few FEMA maps incorporate the risk from street flooding. Many streets (especially in new neighborhoods) are designed to become auxiliary storage for stormwater during major events.

5. Look upstream—not just nearby.

Most buyers look at the kitchen. Look at the entire watershed.

Questions you should ask include:

The house itself may not have changed. But the watershed may have.

Pay particular attention to upstream land-use change. In rapidly growing watersheds such as Spring Creek, Lake Creek, Cypress Creek and the San Jacinto River basin, today’s flood risk is not necessarily tomorrow’s. A home that has never flooded can become more vulnerable given rapid upstream development, insufficient mitigation or changing channel conditions.

6. Study the neighborhood’s drainage.

Some homes flood because of rivers. Others flood because streets become rivers.

Ask:

  • How quickly does water leave?
  • Are storm sewers undersized?
  • Is there ponding after ordinary thunderstorms?
  • Do roads become impassable before houses flood?

Access matters. Especially during emergencies. A dry house isn’t very useful if emergency vehicles can’t reach it.

7. Budget insurance before buying.

Many buyers discover the insurance cost after they’ve emotionally committed.

That’s backwards. Get actual quotes first.

Compare:

  • National Flood Insurance Program
  • Private flood insurers

Remember:

  • Homeowners insurance generally does not cover flooding
  • Flood insurance usually has a 30-day waiting period.
  • Under Risk Rating 2.0, premiums now vary substantially depending on elevation and risk characteristics. FEMA no longer quotes nationally subsidized prices based solely on flood zones. Quotes are now on an actuarial basis.
8. Think about resale.

Ask yourself:

“If I needed to sell this house in ten years, would someone else hesitate for the same reasons I’m hesitating today?”

Flood disclosure laws are becoming more robust.

Insurance costs are becoming more visible.

Risk information is easier to obtain than it was 15 years ago.

Future buyers may discount flood-prone properties more heavily than previous generations did.

9. Separate emotional value from financial value.

Water views have real value. They also have real costs.

Ask yourself:

  • Is the view worth an extra $100,000?
  • Would it still be worth it if my insurance doubled?
  • What would happen to my equity after a major flood?

Only buyers can answer those questions. And remember: a home in a 100-year floodplain has a 1-in-4 chance of flooding during the life of a 30-year mortgage.

10. Look for evidence of thoughtful engineering.

Examples include:

  • Higher slabs
  • Additional freeboard beyond minimum code requirements
  • Pier-and-beam construction where appropriate to let water flow under homes
  • Effective site drainage
  • Preserved natural floodplains
  • Elevated HVAC equipment
  • Backflow preventers
  • No history of repeated repairs

Minimum code is just that—a minimum. Builders who voluntarily exceed it often produce more resilient homes.

A study by former Harris County Engineer John Blount found higher building codes reduced flood damage by 20X during Harvey.

Bottom Line

In Houston, water itself isn’t the risk—low elevation is.

Some of the region’s finest neighborhoods are built around lakes, rivers, and bayous and have experienced little flooding because they’re situated on high ground. Others have flooded multiple times despite looking attractive on a sunny day.

When evaluating property, think like an engineer, not a tourist. Ask, “Where will the water go during the worst storm of the next 30 years?” If no one can answer that satisfactorily, keep looking.
