Surface Drainage Systems Los Angeles

Professional surface drainage systems in Los Angeles for foundation protection and water management.

Local Surface Drainage Expertise

In Los Angeles, standing water and poor drainage damage properties fast. We design and install surface drainage systems that redirect water away from foundations, driveways, and landscaping. Whether your lot slopes the wrong way or heavy rains pool near structures, we solve it with grading and drainage solutions built to last.

How We Work

We start with a site walk to understand your water flow, then design a drainage plan that matches your property and Los Angeles building codes. Our team handles permitting, installation, and final grading to ensure water moves away from structures safely.

Site Assessment

We walk your property, map slopes and water patterns, and identify problem areas where pooling or runoff threatens structures.

Drainage Design

We create a grading and drainage plan using contours and swales to direct water safely. Plans meet Los Angeles municipal code requirements.

Grading & Install

Our crew executes grading, installs swales or French drains, and reshapes the lot to match the design. We work through final surface prep.

Final Inspection

We verify slopes, test drainage paths, and confirm the system moves water correctly during light rain. Los Angeles inspectors sign off on code compliance.

You'll always know what's happening next—and when.

Our Services

We handle the full range of drainage work for Los Angeles properties—from residential lot grading to commercial site drainage systems.

Surface Drainage & Grading

Most Los Angeles properties need slopes adjusted to guide rainwater away from foundations and driveways. We regrade your lot using proper contours and install surface drainage features—swales, berms, and catch basins—to eliminate standing water.

Our work meets Los Angeles grading code and prevents erosion on hillside properties common in neighborhoods like the Hollywood Hills and surrounding foothills.

French Drain Installation

Subsurface French drain installed around foundation in Los Angeles.

When surface drainage alone won't work—such as on flat lots or near foundations—we install French drains. These perforated pipes wrapped in filter fabric collect groundwater and direct it safely to a daylight outlet or municipal storm system.

Los Angeles properties in areas like the San Fernando Valley often benefit from subsurface drains because of clay soils and heavy seasonal rains.

Erosion Control & Landscape Integration

Proper drainage protects your landscape and prevents erosion. We design swales and drainage paths that carry water while blending with your landscaping. Native plants and permeable surfaces keep the lot stable during Los Angeles rainy season.

Communities in the Santa Monica Mountains and foothill areas especially need erosion control alongside drainage work.

Why It Matters

Poor drainage is invisible until it fails. Then it costs thousands in foundation repair, landscaping loss, and structural damage.

Prevent Foundation Damage Before It Starts

Water pooling near your foundation causes cracks, settling, and costly repairs. A properly designed drainage system directs water away from structures and prevents these problems from the start.

Los Angeles homes, especially older properties and those in areas with heavy winter rains, benefit from professional assessment and grading before problems appear.

Protect Your Landscaping & Outdoor Spaces

Uncontrolled runoff erodes soil, kills plants, and leaves wet spots in yards. Proper surface drainage keeps your landscape healthy and usable year-round.

We integrate drainage into your landscape so the system works hard while staying invisible—no ugly trenches or visible pipes.

Serving Los Angeles and Surrounding Areas

We serve residential and commercial properties throughout Los Angeles and the surrounding region.

Local Expertise in Los Angeles Conditions

Los Angeles drainage challenges are unique: clay and silty soils, seasonal heavy rains, and building codes specific to the city and county. We know what works here because we do this work every day.

20+ years of experience with Los Angeles grading code, municipal permitting, and hillside properties.

What Are the Best Drainage Solutions for Los Angeles Properties?

The best drainage solution combines surface grading with subsurface drains when needed. Most Los Angeles properties benefit from proper lot regrading, swales, and catch basins. Properties on clay soil or near foundations often need French drains too. We assess your site and recommend the combination that works for your soil, slope, and rainfall.
