Star, Idaho · Irrigation & Yard Drainage
Getting water where it belongs on open ground with very little fall
Altavera Construction designs and installs irrigation and drainage systems for homes and acreage in Star, Idaho, from drip and rotor zones to French drains and regraded swales. Star yards sit on open, mostly flat ground where water has little natural fall, so runoff tends to pool instead of leaving. We plan the underground first, tie into pressurized irrigation or ditch water where it applies, and build the yard on top of it.
The Star Water Problem
On open, gently sloped ground, the challenge in Star is less about how much water you have and more about getting it to the right place.
Star's appeal is the open ground north of the Boise River: wide lots, long views, and room for horses. That same flatness makes drainage tricky. When a yard has almost no natural fall, roof water and sprinkler overspray have nowhere obvious to go, so they collect against foundations, along fence lines, and in the low corner nearly every lot seems to have. Former fields turned into subdivisions add a wrinkle, because building pads get graded while the finished yard grade is often left for the homeowner to sort out. Moving water on gentle ground takes measured slope, not guesswork.
Water in Star also comes from more than one place. Subdivision homes usually run lawns and beds on pressurized irrigation, a separate non-potable system that is only available seasonally, so controller programming and winter shutdown both need a plan. Acreage off State Highway 44 or out toward Highway 16 may rely on canal or ditch water delivered on a rotation, and some rural properties draw from a well. Each source behaves differently in pressure, debris, and timing. A layout that works on a small lot in town can fall short on several acres fed by a ditch, which is why the water source is the first thing we ask about.
Wind is the other Star factor. Open fields and young subdivisions have few mature trees to slow it down, so fine spray drifts onto driveways and fences while the lawn edge stays dry. Lower-trajectory rotors, matched nozzles, and drip in planting beds keep water where it is supposed to land. On larger properties the distances grow as well: long mainline runs to a back pasture, a horse paddock that stays muddy every spring, or a shop pad that sheds water toward the house. If hardscape is on your list too, see how paver patios in Star fit into the drainage plan.
How Altavera handles it
We walk the Star property with water in mind: where it lands, where it sits, and where it can practically go. Grading and drainage are set first, irrigation mains and sleeves go in second, and every zone is planned around your actual water source, wind exposure, and the plants it needs to feed.
What We Install in Star
01
Each zone is matched to what it waters. Drip feeds beds, trees, and windbreak rows with slow, targeted water. Spray heads cover smaller lawn panels, and rotors throw longer distances on big Star lots and acreage lawns. Heads are spaced for head-to-head coverage, and nozzles are chosen with the prevailing wind in mind, so the lawn edges get watered instead of the driveway.
Includes
02
We connect your system to the water you actually have: pressurized irrigation in a subdivision, a ditch or canal source on acreage, or a well. Smart controllers adjust run times to the weather, so a hot, windy week and a cool, rainy one get different schedules. We program the controller, label every zone, and walk you through running it and shutting it down for winter.
Includes
03
When water collects in a low spot, a French drain or catch basin gives it a way out. French drains use perforated pipe in a gravel trench to collect water spread across a soggy area. Catch basins grab surface water at a single point and carry it through solid pipe to a planned outlet. On flat Star lots, where that outlet goes matters as much as the drain itself.
Includes
04
Sometimes the fix is in the dirt, not the pipe. We reshape the grade so the ground falls away from the house, then cut shallow swales along property lines or between pastures to carry runoff somewhere it can go. On gently rolling Star ground, a well-placed swale can move a lot of water with no buried pipe at all. Where grade changes get steeper, retaining walls in Star may be part of the plan.
Includes
05
Linear channel drains catch sheet water at the edge of a patio, driveway, or garage apron before it reaches the house or a door threshold, then send it underground to a safe outlet.
06
Gutters that empty right next to the foundation are easy to fix before landscaping goes in. We connect downspouts to buried solid pipe and carry roof water out to a pop-up emitter, swale, or drain line.
07
Before a patio, walkway, or driveway extension goes in, we run empty sleeves beneath it so irrigation lines and low-voltage wire can cross later without anyone cutting into finished hardscape.
Why One Crew Matters
Irrigation and drainage share the same ground, so we treat them as one system. When one team plans both, the sprinklers stop feeding the soggy spot the drain was supposed to fix.
Here is what that looks like on a Star property.
01
Grading, swales, and drain lines go in first, so later work like sod, beds, or a new patio sits on ground that already sheds water away from the house.
02
Pressurized irrigation, ditch water, and wells each deliver water differently. We plan zones, valves, and controller schedules around the source on your property instead of using one layout for every yard.
03
Open Star lots catch steady wind. Head choice, nozzle angle, and drip in beds reduce drift and overspray so water ends up on plants rather than fences and pavement.
04
Drainage, irrigation, hardscape, and landscaping run through a single team, so you are not coordinating separate contractors or sorting out who dug through whose pipe.
Who Calls Us in Star
Many newer Star homes come with a graded pad, a few downspouts, and not much else. We set the finished grade, route roof water away from the house, and install a full irrigation system on pressurized water before sod and beds go in, so the yard starts out right instead of getting patched later.
Larger properties bring long irrigation runs, ditch or well water, and paddocks or arenas that stay muddy after spring storms. We plan mainlines, zones, and swales across the whole footprint so water reaches distant lawns and trees and drains away from barns, shops, and gravel areas.
If water sits in a corner of the yard, along a fence, or near the foundation after every storm or sprinkler cycle, the cause is usually grade, roof water, or overwatering. We find which one it is, then fix it with regrading, a French drain, catch basins, or better zone coverage.
Older Star homes and acreage often have systems that grew one zone at a time, with mismatched heads and a basic timer. We redesign the layout, replace worn components, add a smart controller, and get coverage even across the property.
From First Call to Final Zone Test
A free 15-minute call to talk through where water pools, what your current sprinklers do, and whether your property runs on pressurized, ditch, or well water.
An estimator reviews what you shared and confirms the work fits our outdoor scope before anyone heads out to the property.
We walk the Star property, read the slope, find low spots and downspouts, check the water source, and note wind exposure and any existing zones.
You receive a written scope covering drainage work, zone layout, controller, sleeves, and the order each phase happens in.
A deposit reserves your place on the schedule. The start is set once the signed proposal and deposit are in.
Grading, swales, and drains go in first. Irrigation mains, valves, and sleeves follow, then any hardscape, with planting and sod finished last.
We run every zone with you, confirm water drains away from the low spots, and go over the controller so you know how the system operates.
Where We Work
Altavera installs irrigation and drainage across Star, from newer subdivisions along the State Highway 44 corridor to rural acreage and horse properties on the Canyon County side of town. We also serve nearby Treasure Valley communities including Eagle, Middleton, Meridian, Nampa, and Caldwell, with the same drainage-first approach on every property.
If your irrigation or drainage scope requires a permit, Altavera pulls it and handles the process with the City of Star's building office, or with Ada or Canyon County when the lot is unincorporated.

FAQ
Cost depends on the size of the area, the number of zones, the water source, and how much grading or drain line the site needs. A quarter-acre subdivision yard on pressurized irrigation is a very different scope from multi-acre property fed by a ditch. We provide pricing in a written proposal after walking the property, and third-party financing options are available.
Yes. Most Star subdivisions deliver lawn and landscape water through a seasonal pressurized irrigation system, and we design the zones, valves, and controller to work with it. We check the available connection during the site visit and plan zone sizes around the pressure you have, so heads do not starve at the far end of the yard.
Yes, we plan irrigation for acreage that uses canal or ditch water, as well as properties on a well. Ditch water arrives on a rotation and can carry debris, so the layout, zone sizing, and schedule have to account for that. We look at your delivery setup and the ground the system needs to cover before we propose a design.
Pooling on a flat Star lot usually means the ground has little or no fall away from the house, or roof water is dumping where it cannot leave. Small dips that are hard to see hold water after storms and sprinkler cycles. We check the grade, then correct it with regrading, a swale, a French drain, catch basins, or downspout routing.
We reduce drift by choosing lower-trajectory nozzles, spacing heads for full coverage, and using drip in beds instead of spray. Open Star neighborhoods with young trees get steady wind, so we also set controller schedules for calmer parts of the day. Together these keep water on the lawn and off fences, siding, and pavement.
No. Our drainage work is outdoors: grading, swales, French drains, catch basins, channel drains, and downspout routing that move surface water away from the house. That often helps a home that sees water near the foundation, but we do not waterproof basements or repair foundations. If you have interior leaks, a waterproofing or foundation specialist is the right call.
It depends on the scope and where the property sits. When a permit is required, Altavera pulls it and manages it with the City of Star's building office, or with Ada or Canyon County for unincorporated lots. We review this during planning so permitting is handled before work begins.
