Drainage Installation & Repair for HOA & Commercial Properties
Southern California gets its rain in arguments — months of nothing, then an atmospheric river with opinions. Greenhouse installs and repairs French drains, area drains, and slope drainage for associations and commercial properties across Orange County and Los Angeles County, so the water leaves before the liability arrives.
Water is the cheapest problem you'll ever ignore expensively
Every drainage call starts the same way: a condition everyone has walked past for two years. The turf corner that squishes in August. The walkway that grows algae each winter. The planter that drains against the clubhouse foundation. None of it looks urgent until an El Niño winter stacks three storms in ten days — then the same conditions become a slip-and-fall claim, a flooded garage, or a slope failure with a six-figure repair attached. Drainage is the rare line item where the fix costs a fraction of any one of the outcomes it prevents.
What we install and repair
French drains for water that sits in soil; area drains, catch basins, and solid-pipe runs for water that arrives on the surface; downspout tie-ins that get roof water off planted beds; regraded swales where the original grading quietly disappeared under years of mulch. On slopes: terrace-drain and v-ditch clearing and repair, subsurface collection at weeping slope toes, and outlet work that puts water where it's legal to put it. Trenching, pipe, gravel, and compaction all run on equipment we own — the same trenchers our irrigation work has always required — so the schedule we quote is the schedule the rental counter can't break.
Drainage, slopes, and fire season are one system
In the hill communities we serve, drainage can't be scoped alone. A slope that burned or was cleared for defensible space sheds water faster the next winter. A failing slope irrigation system adds water a hillside was never graded for. And erosion at a slope toe is usually a drainage failure wearing a landscaping costume. We wrote up how these pieces interlock in our guide to handling drainage, slopes, and fire season together — the short version is that the contractor who maintains your slopes and irrigation is the one who should be moving your water.
Scoped for boards, timed for storms
Drainage work in an association needs a paper trail: photos of the ponding, a written cause, a scope with a price, and an approval before the trencher starts. We build that file for your board or manager, and we push the calendar honestly — the right month to approve drainage work is September, not the week the forecast turns. It folds naturally into an HOA landscape maintenance contract, where drains get checked and cleared as part of the routine HOA maintenance visit instead of rediscovered every December. On commercial property the stakes change with the use: standing water at an office park is a nuisance, while on a medical campus it is a fall hazard for patients on walkers and an infection-control question, which is why we scope drainage there as a safety item rather than a landscape one.

Is standing water on common areas really an HOA liability issue?
Yes, on several fronts at once. A puddle that persists across a walkway is a slip hazard; water ponding against buildings threatens foundations and stucco; and stagnant water on common area draws mosquito complaints that vector-control agencies take seriously. When the association knows about ponding and leaves it, the incident file writes itself. Draining it is cheaper than defending it.
What is a French drain, and when is it the right fix?
A gravel-filled trench with perforated pipe that collects subsurface water and moves it to a legal discharge point. It is the right tool when water sits in soil — soggy turf that never dries, seepage at the base of a slope, chronic wet spots against footings. When water arrives on the surface in a rush, area drains and catch basins tied to solid pipe are the better answer. Most real properties need some of each, which is why we scope before we prescribe.
Can you fix drainage on our slopes?
Slope drainage is where we started caring about this. Terrace drains and v-ditches clogged with sediment, slope toes that weep all winter, and irrigation overspray saturating a hillside are the standard failure set in OC and LA foothill communities. We clear and repair the concrete drainage, add subsurface collection where the slope needs it, and — because we also maintain slope irrigation — stop the water that was being added to the problem daily.
When should drainage work be done — before or after the rainy season?
Before, and earlier than most boards think. Board approval, scheduling, and the work itself take weeks, and drainage contractors’ calendars fill as soon as the first storm forecast appears. The associations that scope drainage in late summer own the calendar; the ones that call in January join a waiting list while the water keeps arriving.
Do you own trenching equipment, or does that get rented?
Owned. Trenchers, compaction equipment, and the pipe and grading tools drainage work runs on are on our trucks — a detail HOA boards increasingly ask about when vetting contractors, because rental delays are how a two-week drainage job spends a month open. Trenching is also half of irrigation work, which we have done from the beginning.
Standing water is a decision. Make a different one.
