Prepare for flooding and drought as one household water plan: learn your local hazards, make an evacuation and communication plan, protect the building from incoming water, reduce leaks and unnecessary demand, and manage the yard so it can absorb rainfall without wasting irrigation. The right combination depends on your flood exposure, soil, slope, foundation, climate, water utility and local rules.
This guide is U.S.-focused because it relies on FEMA, Ready.gov and U.S. Environmental Protection Agency guidance. Check your local emergency-management office, building officials, health department and water utility before changing a drainage system, elevating equipment or using water during a restriction.
How do I prepare my home for flooding and drought?
Start with these priorities, in order:
- Assess both hazards locally. Review FEMA and local flood information, sign up for emergency alerts, and ask your water utility how it announces drought stages and restrictions.
- Make a household plan. Set evacuation routes and a destination, establish a way to communicate, and account for pets, medicines, mobility needs and important documents.
- Reduce flood damage. Keep gutters and drains clear, move valuables above likely flood levels, and consider a check valve or battery-backed sump pump where a sump system is appropriate.
- Reduce drought demand. Find and repair leaks, follow utility restrictions, replace worn fixtures with WaterSense-labeled models when practical, and limit nonessential outdoor watering.
- Use the landscape for both hazards. Choose plants suited to the local climate, improve soil and mulch, maintain irrigation to prevent runoff, and consider a rain garden only where site conditions and local requirements support it.
No measure makes a home completely floodproof or guarantees water during a drought. Treat each item as risk reduction, and obtain qualified advice for structural work or unusual sites.
Assess local conditions before buying equipment
Check flood exposure, including areas outside mapped zones
Use FEMA and local hazard information to understand whether your address, access roads and evacuation routes could flood. Ready.gov warns that flooding doesn’t follow lines on a map. Where it can rain it can flood.
Read the current Ready.gov floods guidance, then check local maps, past flood reports and warnings from your emergency-management office. A map is a planning tool, not a guarantee that an unmapped property is safe.

Sign up for local emergency alerts and identify more than one route to higher, safer ground. Ask whether your community uses outdoor warning sirens, text alerts, weather radio or another system, and decide who monitors alerts when household members are apart.
Ask the water utility about drought stages
Your water source, supply outlook and restrictions are local. Ask the utility whether restrictions are active, which uses are considered essential, how lawn and garden watering is scheduled, and how violations or exemptions are handled. The EPA’s Drought & WaterSense guidance says to follow utility rules so water remains available for critical needs, including firefighting. Do not rely on a neighboring town’s schedule or an old newspaper notice.
Review insurance and records before an emergency
Ready.gov says standard homeowners insurance does not cover flooding. A separate flood policy typically takes up to 30 days to become effective, although eligibility and waiting-period exceptions vary. Review current terms, exclusions, deductibles and the waiting period directly with your insurer or the National Flood Insurance Program before a storm threatens. Photograph major rooms and equipment, store receipts, and keep policy information where it can be reached after an evacuation.
Make a household flood plan
Write the plan down and practice it. The FEMA flood hazard information sheet and Ready.gov provide the safety foundation; your local officials provide the route and shelter details.

- Practice the departure. Drive the route in daylight, identify alternatives and decide what can be taken without delaying evacuation. Follow an official evacuation order immediately.
Reduce flood damage around the house
Flood measures are site-specific. The table distinguishes actions that most households can inspect from work that requires design or professional review.
| Measure | Primary benefit | When it may fit | Important limits and checks |
|---|---|---|---|
| Move valuables and documents higher | Reduces loss from shallow or rising water | Every home, especially homes with low storage or a basement | Use waterproof containers for paper records; elevation does not protect the structure or utilities. |
| Clear gutters, downspouts and drains | Helps rainfall leave the roof and site instead of backing up | Every home; inspect before rainy seasons and after debris-producing storms | Confirm that discharge does not send water toward a foundation or neighboring property. |
| Check valve on drain lines | Can reduce sewer backflow through fixtures | Properties where local plumbing officials approve the device | Installation and maintenance are local-code matters; it does not stop surface flooding. |
| Battery-operated sump pump or backup | Can keep a suitable sump system working during a power outage | Homes with a basement or below-grade drainage system that already uses a sump | Size, pump capacity, discharge location, battery maintenance and electrical arrangements must match the property. It is not a guarantee against flooding. |
| Elevate critical utilities | Moves electrical, heating, water or other equipment above expected floodwater | Renovations or retrofits where local flood elevations and codes permit | Do not choose a universal height. A building official or qualified mitigation professional should set the design level. |
| Sandbags or temporary barriers | May redirect limited shallow flows for a short time | Situations identified by local emergency officials | FEMA lists sandbags as a possible barrier, but they do not make a property floodproof and can fail when deployed late or in the wrong location. |
| Structural flood retrofit | Can reduce recurring damage to the building | Homes with repeated or significant exposure | Obtain an engineering assessment and permits. Do not seal a home against floodwater without professional design; water pressure and soil conditions can make blanket sealing unsafe. |
Keep water away from openings without creating a new drainage problem
Inspect foundation walls, window wells, doors, downspouts and low points for routes water already takes. A change that sends runoff onto a foundation, septic field or neighboring lot can worsen damage. For grading, barriers, drainage alterations or structural floodproofing, consult local building officials and a qualified flood-mitigation professional rather than relying on a generic online detail.
Use a sump system deliberately
A battery backup sump pump is relevant only when a sump pit and discharge route are appropriate for the property. Ask an installer to confirm pump sizing, the backup’s run time, a safe discharge point and protection from freezing or blockage. Test the primary and backup systems on a schedule, clean the pit and replace batteries according to the manufacturer’s instructions. A pump cannot remove water that enters faster than its design capacity, and it will not solve groundwater, sewer or surface-flow problems by itself.

Find leaks before cutting consumption elsewhere
Check toilets, faucets, shower connections, water-heater fittings, exposed pipes and irrigation valves. Look for damp cabinets, staining, sounds when no fixture is running and unexplained meter movement. Repair leaks promptly: EPA’s Home Maintenance guidance notes that leaks waste water and can also cause serious household damage. If a leak is inside a wall, at a main line or beyond your skill level, use a licensed plumber.

Replace fixtures when they need replacement
When a toilet, showerhead, faucet or irrigation controller reaches the end of its useful life, consider an EPA WaterSense-labeled model. WaterSense products are certified to use less water while meeting performance criteria; the label is a performance qualification, not a promise that every household will save the same amount. Compare the product’s installation requirements and performance with the existing plumbing rather than replacing a working fixture solely for a label.
Check your utility for rebates or free retrofit programs, but treat them as possibilities rather than guaranteed benefits. Availability, eligible models, application deadlines and funding change by location.
Keep essential water available during restrictions
During a drought, follow the utility’s current schedule and permitted-use list before watering, washing vehicles or filling pools. A restriction may allow health and safety uses while limiting lawn irrigation. The EPA states in Drought guidance that local conditions determine the response; do not substitute a private well assumption or a social-media schedule for an official notice.

Outdoor demand is often the largest adjustable use. EPA WaterSense reports that outdoor use accounts for about 30 percent of an estimated 29 billion gallons of household water used daily in the United States, and can reach 70 percent of household use in hot summer months or dry climates. These are national estimates, not a measurement of your property.

Choose plants for the climate and the site
Select native or drought-tolerant plants suited to your region, sun exposure, soil and mature size. Group plants with similar water needs so one irrigation schedule does not overwater some and stress others. Replace a failing lawn gradually if local rules, wildfire considerations or erosion control make that appropriate; bare soil can create runoff and erosion, so establish ground cover deliberately.
Improve soil and mulch correctly
Maintain soil with organic matter appropriate to the site, avoid compacting planting areas and use mulch to reduce evaporation and splashing. Keep mulch away from siding, vents and woody stems, and do not use a soil amendment or mulch layer that blocks drainage near a foundation. The EPA’s Landscaping Tips explain water-saving landscape practices while recognizing that local conditions matter.
Maintain irrigation to prevent waste
Inspect emitters, hoses, valves and sprinkler heads for breaks, overspray and runoff. Adjust zones for plant needs and weather, and repair leaks before extending watering time. Water only when permitted and needed; a timer does not override a utility restriction. Keep spray off sidewalks, driveways and buildings, where it evaporates or runs into drains instead of helping plants.
Use one landscape plan for both extremes
A drought-smart yard can also help manage ordinary stormwater, but the two goals are not identical. Drought planning reduces unnecessary irrigation; flood planning safely routes or stores rainfall. Combine them only after checking soil, slope, groundwater, foundation setbacks, septic systems, utilities and local requirements.

| Landscape choice | Drought contribution | Flood or stormwater contribution | Site questions |
|---|---|---|---|
| Climate-suited planting | Needs less supplemental irrigation once established | Roots and vegetation can slow some surface flow | Will mature roots, shade and maintenance suit the property? |
| Healthy soil and mulch | Holds moisture longer and reduces evaporation | Can improve infiltration in appropriate planting areas | Is the soil compacted, contaminated or already saturated? |
| Drip or targeted irrigation | Applies water near roots with less overspray | Reduces runoff caused by excessive spray | Can the system be maintained and shut off during rain? |
| Rain garden or planted depression | May reduce irrigation needs for suitable plants | Can temporarily receive and infiltrate roof or yard runoff | Check soil infiltration, slope, groundwater, foundation distance, utilities and local approval first. |
EPA identifies rain gardens as one possible landscape feature, not a universal solution. Do not direct concentrated roof runoff toward a foundation or assume that infiltration is safe on every lot. A landscape designer, soil professional or local drainage official can identify setbacks and overflow routes.
Understand what a WaterSense home claim means
For new construction, EPA says a WaterSense-labeled home is at least 30 percent more water-efficient than a typical new home under the program specification. EPA also reports an average program-level estimate of 50,000 gallons of water and $700 in water and energy bills saved per year for a family in a WaterSense-labeled home. The figures come from EPA’s program pages, including Building WaterSense Labeled Homes and Homes, accessed in 2026. They describe labeled new homes on average, not a guaranteed result for a retrofit or a particular family.
For an existing property, use the label as one selection criterion for replacement fixtures and irrigation equipment. Actual savings depend on the old product, household behavior, local water rates, climate and maintenance.
A practical preparation schedule
Do this now
- Record local emergency-management and utility contacts, sign up for alerts and review flood information.
- Write the household communication and evacuation plan, including pets, prescriptions and mobility needs.
- Inventory valuables, photograph rooms and place documents in a waterproof container with digital copies.
- Walk the property after rain to observe ponding, blocked drains and water moving toward the foundation.
- Check for indoor, outdoor and irrigation leaks.
Complete before the next wet season
- Clean gutters, downspouts, yard drains and window wells; verify that discharge does not damage the foundation.
- Have a suitable sump system, check valve or utility elevation reviewed where local conditions justify it.
- Ask building officials before altering grading, adding barriers or undertaking structural flood work.
- Confirm insurance coverage and the flood-policy waiting period.
Complete before the next dry season
- Repair plumbing and irrigation leaks and test shutoff valves.
- Program irrigation only within the utility’s permitted schedule and adjust zones for plant needs.
- Replace failed fixtures with WaterSense-labeled products when practical and check local rebate rules.
- Mulch and establish climate-suited plants before the hottest period, allowing time for roots to develop.
Recheck every season
- Test sump equipment and maintain batteries, alarms and discharge lines.
- Refresh contact lists, medicines, food, batteries and pet supplies.
- Review new utility restrictions, flood notices, construction changes and insurance terms.
- Inspect irrigation after storms and before the first scheduled watering.
What to do when flooding threatens
Follow official evacuation orders and leave early enough to avoid blocked routes. Never walk, swim or drive through floodwater. Water may conceal debris, open drains, electrical hazards or a washed-out road, and moving water can sweep away a person or vehicle. Do not return until officials say it is safe.
Do not assume tap water is safe after flooding. Follow the local health department or utility notice about boil-water advisories, contamination, treatment and disposal. If floodwater entered the building, keep people and pets away from contaminated areas, avoid energized equipment and arrange qualified inspection before restoring utilities or beginning major cleanup.
What to do during a drought
Use the utility’s current restrictions as the controlling rule. Stop nonessential watering when required, repair failures quickly and prioritize drinking, sanitation, health and safety. If supply, pressure or quality changes, contact the utility rather than improvising a private connection or storage arrangement. Continue to monitor plants and soil: reducing waste does not mean allowing erosion, dead vegetation near structures or unsafe heat exposure.
Common mistakes to avoid
- Trusting a map boundary too much. Flooding can occur outside mapped areas; combine maps with local warnings, drainage observations and evacuation planning.
- Buying a pump before checking the site. A backup sump pump is useful only with a suitable pit, power arrangement and safe discharge route.
- Sealing every opening without engineering. Hydrostatic and hydrodynamic pressure can damage walls or foundations; structural work needs site-specific design.
- Using sandbags as a permanent defense. They may help with limited flows but are not floodproofing.
- Installing a rain garden in the wrong place. Poor soil, a high water table, a steep slope or a nearby foundation can turn infiltration into a drainage problem.
- Ignoring maintenance. A blocked gutter, dead battery, broken emitter or failed valve can defeat an otherwise sound plan.
- Assuming a national statistic is a personal guarantee. WaterSense savings averages and outdoor-use estimates describe populations or program homes; your result depends on the property and household.
The practical standard for a resilient home
A resilient home is not one that relies on a single product. It has a current local-risk assessment, a practiced evacuation plan, protected records, maintained drainage, appropriately designed flood measures, leak-free plumbing, efficient fixtures, a landscape matched to its climate and soil, and a routine for checking utility rules. Build the low-cost planning and maintenance habits first; bring in local officials and qualified professionals before structural, electrical, drainage or infiltration work.
