When a Puget Sound downpour overwhelms a yard, water goes wherever it can, and too often that means pooling against the foundation, seeping toward a crawlspace, or turning the lawn into a shallow lake. Our emergency yard drainage Seattle WA service is about buying you time and protecting the house in that moment, diverting standing and surface water away from the structure fast so an inch of rain doesn't become a flooded basement.
Seattle's soils make this worse. Glacial till and compacted clay drain slowly, so heavy or sustained rain sits on the surface with nowhere to go, and low spots and blocked drainage paths turn into ponds. In an emergency we focus on immediate relief: clearing blocked flow paths, cutting temporary diversions, pumping or channeling standing water, and getting it moving away from where it's causing harm.
We respond quickly across Seattle and the surrounding King and Snohomish county area, and once the crisis is managed we can design a permanent fix, French drains, catch basins, and grading, so the next storm doesn't put you back in the same spot.
When to Call for Emergency Drainage Help
- Water is pooling against your foundation or heading toward a crawlspace
- Standing water is rising across the lawn with nowhere to drain
- A downspout or drain line has backed up or blocked during heavy rain
- Runoff from a slope is sheeting straight toward the house
- Low areas of the yard have become ponds that won't recede
- Water is threatening a garage, shed, or basement entry
What Our Flood Mitigation Includes
Rapid Emergency Response
Fast dispatch during heavy rain events, prioritizing situations where water is threatening a foundation, crawlspace, or living space.
Standing Water Diversion
We channel and redirect surface and standing water away from the structure using temporary diversions, trenching, and pumping to relieve the immediate threat.
Blocked Flow-Path Clearing
We locate and clear blocked downspouts, drain lines, and clogged flow paths that are causing water to back up and pond where it shouldn't.
Foundation Protection
The priority is getting water away from the house, so we focus first on the areas where flooding poses the greatest risk to the structure.
Slope Runoff Interception
For runoff pouring off a slope toward the home, we cut interception paths to catch and redirect it before it reaches the foundation.
Permanent Drainage Follow-Up
Once the emergency is handled, we can design and install a lasting solution, French drains, catch basins, and regrading, to prevent a repeat.
Our Flood Mitigation Process
- 1
Emergency Call & Dispatch
Call (323) 606-0255 and describe where water is going and what it's threatening. We prioritize foundation and living-space risks and dispatch a crew during the rain event.
- 2
On-Site Water Assessment
We trace where water is coming from, where it's pooling, and why, whether from blocked drainage, slope runoff, or saturated ground, so mitigation targets the actual source.
- 3
Immediate Diversion
We act to move water away from the structure fast, clearing blockages, cutting diversions, trenching, and pumping standing water toward safer discharge points.
- 4
Stabilize & Monitor
We confirm water is flowing away from the at-risk areas and address any secondary pooling, stabilizing the situation until the storm passes.
- 5
Permanent Solution Planning
With the emergency contained, we walk you through a durable drainage plan so the same low spot or blocked path doesn't flood again next season.

Flood Mitigation Pricing in Seattle
Emergency drainage response is priced by the severity of the flooding, the work required to divert water, and site conditions. Immediate mitigation is scoped separately from any permanent drainage installation that follows. We're upfront about what the emergency work involves and what a lasting fix would take, so you can decide how far to go.
- Severity and volume of the standing or incoming water
- Source of the problem: blocked lines, slope runoff, or saturated soil
- Amount of trenching, diversion, or pumping needed
- Access to the affected areas during the rain event
- Urgency and timing of the emergency dispatch
- Soil conditions affecting how fast water can be moved
- Scope of any permanent drainage installation that follows
Flooding is a fast-moving problem, and getting water away from the house in the first hour can be the difference between a wet yard and a damaged home. Florentino Landscaping has responded to drainage emergencies across the Seattle area since 2016 as a family-owned, licensed and insured Washington company that knows how our soils and storms behave.
If water is rising toward your foundation, don't wait it out. Call (323) 606-0255 for immediate mitigation, and we'll help you protect the house now and keep it dry later.
Emergency Yard Drainage & Flood Mitigation — Frequently Asked Questions
We dispatch during rain events to divert water away from the structure fast, clearing blocked drains, cutting temporary diversions, and pumping standing water toward safer discharge. The immediate goal is getting water off the foundation to limit damage, then we plan a permanent fix once the storm passes.
Our glacial till and compacted clay soils drain slowly, so heavy or sustained rain sits on the surface. Add low spots, blocked drain lines, or slope runoff aimed at the house, and water ponds fast. Fixing it usually means both correcting flow paths and adding capacity with drains.
Emergency mitigation is fast, temporary work to move threatening water away from the house during a storm. A permanent fix, installed once conditions dry out, uses French drains, catch basins, and regrading to manage water every time it rains so you're not calling for an emergency again.
Fall and early spring are ideal, since you want the system in place before the wet season peaks, and the ground is workable. We can assess during or right after a flood event and schedule the permanent installation for the right window.
A few things help, if you can do them safely. Clear leaves and debris off any grates, drains, and downspout outlets so the water that can drain, does. Move valuables up off a flooding garage or crawlspace floor. If you have sandbags, or even bags of soil, use them to steer water away from doorways and vents. Don't wade into deep or moving water, and stay clear of anything near electrical. Then call (323) 606-0255 and we'll take it from there.
