Drainage and grading that sends water away from the house
Drainage and grading fix the yard that turns into a pond every winter: water standing after rain, a wet line along the foundation, soggy turf, and a slope that sheds mud onto the patio. VC Turf regrades the lot, sets the drains, and adds erosion control on slopes across Ventura County, as a standalone job or as the first step of a turf, paver, or concrete project.
The finished lot in one drawing: ground pitched away from the house, roof water piped instead of dumped, a French drain catching what soaks in, a basin at the low spot, and one solid line carrying all of it to an outlet where it can leave.
Pick the signs you see after a storm
Each sign points at one of three fixes: regrading, drains, or erosion control. Check the ones that match your yard and the card fills in the likely category. The estimate visit confirms it on the ground.
Nothing checked yet. Pick any sign, or more than one; yards usually have two or three of these at once.
Foundation: regrade so the ground falls away from the wall, and pipe the nearest downspout past the beds.
Soggy lawn: a French drain through the wet area, with the surface reshaped so it sheds toward it.
Slope: terrace it or cover it, and give the runoff a lined channel so it stops cutting the bank.
Patio: a channel drain at the low edge, and a look at the grade around the slab so water is not being pushed onto it.
Downspouts: tie them into solid pipe that runs to an outlet instead of the soil next to the wall.
No prices here on purpose. The estimate confirms the fix and finds where the water can actually go, which is what sets the cost.
Grading comes first: the yard has to fall away from the house
Every drain we set works better when the ground is already tilted the right way. Grading is cutting the high ground and filling the low ground so the lot slopes away from the foundation, then shaping the rest of the yard so water has a route to the street, a swale, or a drain inlet instead of a low spot. On a flat lot we crown the lawn area, a slight high line down the middle, so water sheds to the edges. Where a fence or a neighbor's grade blocks the path, we cut a swale, a shallow, broad channel that carries runoff along the property line without looking like a ditch.
Grading is also why drainage happens before artificial turf, pavers, or concrete, not after. Turf laid over a low spot holds water in the base and the seams open. Pavers over wet ground settle and lift. A slab poured on a soft, wet subgrade cracks and heaves. Fixing the grade while the ground is open costs far less than pulling up a finished surface to get at the problem underneath. When a project starts with demolition and site prep, regrading happens at that stage, before anything new goes down.
The right drain for each kind of water
Water that soaks in and water that runs across the surface need different drains. A French drain handles the first kind: a trench with perforated pipe wrapped in gravel that collects groundwater along a foundation or across a soggy lawn and carries it off. Surface water gets caught at a point. Catch basins and area drains sit at the low spot of a lawn or planter and are tied to solid pipe underground. Channel drains are the long, slotted grates set at the edge of a driveway or patio to catch a sheet of runoff before it reaches the garage or the door.
Downspouts are the biggest single source of water against a house, so we tie them into the same solid pipe instead of letting them dump at the wall. Every drain line needs somewhere to end. Where the lot has fall we run it to daylight, a screened outlet at the low side that discharges to the street or a swale. Where there is nowhere to send it, a dry well, a gravel-filled pit that lets the water soak into the ground away from the house, takes the discharge.
Erosion control that keeps the hillside where it is
A bare slope loses soil with every storm, and the soil ends up on the patio, in the pool, or against the fence. The fix depends on how steep the bank is and what you want to do with it. On a slope you want to use, we terrace it: cut it into flat steps held by block retaining walls, each with drainage gravel and a drain behind it, so you get usable ground and the water has a place to go at every level.
On a slope you just want to stay put, we cover it. Ground cover plants knit the surface with roots. Paths across a bank get stabilized decomposed granite or jute matting that holds the soil until the plants take over. Where runoff concentrates in one line down a hill, a rock-lined dry creek bed gives it a channel that looks like part of the yard and does not scour. These are the same materials we set for decorative rock and ground cover beds, placed here with the water in mind.
Why yards here flood, and what decides the price
This coast goes months without rain and then gets it all in a few winter storms. Dry clay seals on top and sheds water instead of soaking it up, so the first big storm runs across the yard like it is pavement. Hillside lots collect the runoff from everything above them. With no freeze we never fight frost heave, but we do fight ground that goes from rock-hard to mud in one weekend, and the drains have to be in before the rain, not after.
Cost is driven by the work in the ground, not the parts. The length of pipe and the number of catch basins or channel drains set the material side. Excavation sets the labor side: hand-dug trenches around roots and utilities take longer than open ground a machine can cut. Where the water can go matters most. A lot with fall to the street gets a daylight outlet; a flat lot may need a dry well or a longer run. Slope work, terracing, and walls are priced as their own line, and you get one written number that covers all of it.
VC Turf is a California licensed contractor, CSLB #1036018. Drainage and grading is sold on its own and is also built into the rest of our outdoor hardscape services, so one crew owns the water and the surface over it. If you only need one downspout piped away from the wall, that is a job we take.
What happens on the day
The crew marks the lines and outlets, has underground utilities located where the trench crosses them, then cuts the trenches and sets the fall with a level. Pipe, gravel, basins, and the outlet go in, the trenches are backfilled and compacted, and the surface is put back or left graded for the next trade. Turf or pavers over a trench line are cut and reset, not left as a scar.
Before the rainy season
Grates on catch basins and channel drains collect leaves; clear them a few times a year and before the first storm. Walk to the outlet each fall and make sure it is open and the screen is clear. Keep mulch and soil out of the swale so it stays a channel. A French drain wrapped in fabric rarely needs attention, and a dry well needs none until it slows down.
What people ask before a drainage job
Yes. Most drainage and grading work is trenching and shaping in the problem area, so a soggy strip along the fence or one downspout gets its own fix and the rest of the yard is left alone. Where a trench has to cross finished turf or pavers, that strip is lifted and put back when the pipe is in.
It works when it is built for clay: a wider trench, clean gravel, fabric that keeps fines out of the pipe, and enough fall that the water leaves instead of sitting in the trench. In clay the surface shape matters as much as the pipe, because clay sheds water before it soaks in, so we usually pair the drain with a regrade of the ground above it.
To a dry well, or to the street where the city allows a curb outlet, through the longest run with the least fall we can find. On a flat lot we also lean harder on shaping: a crowned lawn and a swale move water a long way with no pipe at all. The estimate visit is where we find the answer, with a level in hand and a look at where the last storm left its mud.
No. Photos from last winter help if you have them, and the rest can be read in the dry: the fall of the ground, the stain line on the stem wall, the silt fan below a slope, the moss on the shady side of the lawn. Work done in the dry months is easier to dig and is not racing the first storm.
Same crew, same estimate. Drainage and grading is priced as its own line on a turf, paver, or concrete job so you can see what it covers, and the people who set the drains are the people who build the surface over them, and if the surface ever settles, one company answers for it.
