Drainage Work We Provide in Sacramento
Drainage support is earthwork-focused — we regrade, trench, and install drainage infrastructure. Pipe connections and drain basin outlets to the storm system involve the city — we coordinate that scope with you.
- Site regrading — correct flat or inverted grade to positive slope away from structure
- French drain installation — perforated pipe in gravel trench, outlet to daylight or basin
- Surface swale construction — vegetated or rock-lined channel to redirect surface flow
- Drain basin and outlet installation
- Retaining wall drainage backfill — drain rock and filter fabric
- Downspout diverter trenching and pipe runs
- Low-spot fill and regrading in rear yards and along property lines
Why Sacramento Drainage Problems Are So Common
Sacramento Valley clay loam doesn't drain — it's nearly impermeable when saturated. Older lots were graded with minimal attention to drainage slope. Add decades of soil settlement and the result is flat lots that pool in winter.
- Clay loam permeability: nearly impermeable when saturated — surface water doesn't percolate
- Older neighborhoods (Land Park, Curtis Park, Pocket-Greenhaven) graded decades ago without modern drainage standards
- Flat topography: Sacramento Valley floor has minimal natural drainage gradient
- Seasonal rainfall (Nov–Mar): 16–20 inches annually, concentrated in winter months
- Tree roots disrupting French drains and perforated pipe in older drainage systems
- Pocket-Greenhaven specifically: low elevation near Sacramento River, historically flood-prone
Drainage Permits and City Connections in Sacramento
Minor regrading and French drain installation generally don't require permits in Sacramento. However, connecting a drainage outlet to the city storm drain system requires coordination with Sacramento Public Works and may require a connection permit.
- Regrading and French drain: typically no permit if work is entirely on private property
- Storm drain connection: permit required from Sacramento Public Works
- Sanitary sewer cannot receive drainage water — only storm system or daylight outlet
- FEMA flood zone properties (near Sacramento/American rivers): additional requirements may apply
- Drainage improvements that alter surface flow onto neighboring property may require civil review
Planning a drainage support project in Sacramento?
Pre-Sale Pool Removal
Pool Removal Before Selling in Sacramento, CA
If the pool is old, leaking, expensive to maintain, or blocking the yard's best future use, removal can make the listing cleaner. The right answer depends on timeline, buyer profile, future-build potential, and whether you choose partial fill-in or full removal.
ADU Site Prep
Lot Clearing for ADUs in Sacramento
ADU projects usually fail early when the backyard is not actually build-ready. Clearing, demolition, access, rough grading, utility trench planning, and pad prep should be sequenced before the foundation crew is scheduled.
Build-Ready Site Prep
Site Prep for New Construction Sacramento
New construction starts cleaner when clearing, demolition, rough grading, drainage, access, and pad readiness are handled before the building crew arrives. The goal is not just an empty lot; it is a site ready for the next trade.
Sacramento ADU Site Prep
ADU Site Preparation in Sacramento, CA
Sacramento infill lots usually need more than a quick clear before an ADU pad can be poured. Old detached garages, narrow side gates, alley access, mature tree canopies, and aging pools all change the prep sequence. We help prepare the site for the foundation crew so the build doesn't stall on backyard surprises.
Frequently asked questions
Why does my Sacramento yard flood in winter?
Most likely a combination of flat grade, Sacramento clay loam that doesn't drain, and inadequate or absent drainage infrastructure. Land Park, Curtis Park, and Pocket-Greenhaven lots are particularly prone. The fix is regrading to positive slope plus a French drain or surface swale system to move water to a proper outlet.
How much does drainage correction cost in Sacramento?
Residential drainage correction in Sacramento typically runs $2,000–$10,000. Regrading alone is $1,500–$4,000 for a standard rear yard. French drain installation adds $1,500–$5,000 depending on linear footage and outlet distance. We quote after a site visit — drainage problems vary too much for accurate phone estimates.
Can I connect a French drain to the city storm drain in Sacramento?
Possibly, but it requires a permit from Sacramento Public Works and approved connection. Many residential lots outlet to an adjacent street gutter instead — the water enters the storm system via the gutter, which avoids a direct connection permit. We can assess your outlet options during the estimate.
Will regrading fix a Sacramento foundation moisture problem?
Regrading to positive slope away from the foundation is the first and most cost-effective drainage fix. It won't solve every foundation moisture problem — rising groundwater, cracked foundation walls, or failed waterproofing are separate issues — but correcting surface drainage eliminates the most common cause of foundation wet-season moisture in Sacramento neighborhoods.
