At a glance

Irrigation and drainage in North County San Diego — smart controllers, drip conversions, French drains, grading and sprinkler repair. Oceanside Landscaping designs and installs NCSD irrigation systems under California license BL-79184. New residential drip systems typically run $1,800–$6,500; French drains $25–$55 per linear foot; smart controller installs from $380. SoCal Water$mart rebates often apply.

§ 01 About this service

Irrigation in Southern California isn’t just about keeping plants alive — it’s a regulated system, an ongoing cost, and the single biggest lever for long-term yard health. We design, install, repair and upgrade irrigation for NCSD homes, HOAs and commercial properties. Drip-first, smart-controller by default, and documented so you always know what each zone is doing.

Water is the quiet line item

Most Southern California landscape budgets don\u2019t fail on plants or hardscape \u2014 they fail on water. Wrong zones, untuned run times, and old pop-up heads in beds that should have been drip years ago. Fixing those is the cheapest landscape upgrade you can make.

Drip-first, smart-by-default

Every new system we install now starts with two defaults:

  • Drip on every non-turf zone. Shrubs, trees, flower beds, succulent gardens, veggie beds, planter pots \u2014 all drip. Pressure-regulated, filtered, calibrated per plant. Less water, healthier roots, fewer fungal problems.
  • Smart controller at the hub. Weather-based programming, flow-sensing, app control. You spend about 20 minutes setting it up and then forget it exists while your water bill drops.

Drainage is part of the system

It\u2019s tempting to think of drainage as a separate category, but in NCSD they\u2019re two sides of the same water conversation. A yard that can\u2019t shed runoff properly is a yard whose irrigation has been compensating for it the whole time. Before we redesign any irrigation system, we look at grades and drain paths \u2014 the invisible work that keeps everything else working.

Rebates you should know about

Smart controllers, drip conversions, and turf removals are all eligible for MWD / SDCWA rebates that often cover 30\u201370% of material cost. We\u2019ll flag what applies to your project in the initial quote.

What’s included

Every piece of irrigation & drainage.

Below is what we actually do under this service. If you don’t see the thing you need, ask — we’ll tell you straight whether it’s ours or someone else’s.

01

Sprinkler System Installation

New systems designed zone-by-zone around plant type, exposure and slope. Rain Bird and Hunter primary components, installed to last.

02

Irrigation Repair & Maintenance

Broken heads, cracked lines, leaking valves, stuck solenoids, low pressure — we troubleshoot and fix in a single visit whenever possible.

03

Drip Irrigation Systems

The most efficient way to water everything except turf. Pressure-regulated, filter-protected, emitter-calibrated to each plant.

04

Smart Irrigation Controllers

Rachio, Rain Bird ESP‑TM2 and Hunter Hydrawise — weather-based adjustments that quietly cut 30–50% off your water bill.

05

Drainage Solutions

French drains, channel drains, dry wells, swales, and grade correction — for yards that pond, driveways that flood, and hillsides that slip.

06

Water Conservation Systems

Rebate-eligible upgrades: smart controllers, drip conversions, greywater hookups, rain sensors and flow meters.

Our process

How a project actually unfolds.

01

Audit the system

We walk every zone, measure flow, test pressure, and find the quiet leaks before we touch anything.

02

Design the fix

You get a zone map, component list, and cost — split into must-do, should-do, could-do.

03

Install & program

Clean installs, hidden heads, labeled valves, controller programmed with your schedule and watering goals.

04

Walk-through & docs

You get a one-page system diagram, zone-by-zone watering schedule, and a contact for any future tweaks.

Where we do it

Eight cities, one crew.

FAQ

Questions we hear before every quote.

If yours isn’t here, the answer is almost certainly “yes, call us”.

How much does a new sprinkler system cost?
Residential installs typically run $2,800–$8,500 depending on yard size, zones, and whether drip is added. A smart controller adds $300–$600. We size every job to your yard, not a template.
Is a smart irrigation controller actually worth it?
In this climate, yes — most clients see 30–50% lower water bills within the first full year. Many also qualify for MWD and SoCal Water$mart rebates that cover part of the install cost. Wi-Fi controllers (Rachio, Hunter Hydrawise, Rain Bird ESP-TM2) pay back in one to two years in NCSD.
What’s the difference between drip and spray irrigation?
Spray covers broad areas — great for lawns, wasteful for shrub beds. Drip puts water at the root — perfect for shrubs, trees and gardens, useless for turf. Most yards need both, zoned separately.
I’ve got ponding after storms. What are my options?
Three most common fixes: French drain (collects water along a trench and pipes it out), channel drain (surface-level, for hardscape), or regrading (reshapes the soil so water runs where you want). We’ll diagnose before quoting.
Do you repair systems you didn’t install?
Absolutely. About half our irrigation work is repairs and upgrades on existing systems. We bring standard Rain Bird/Hunter parts so most fixes happen same-visit.
Can you help with water restrictions?
Yes. We stay current on MWD, SDCWA, and local water-district rules across NCSD. We’ll recommend compliance-first designs, flag rebate opportunities and pull permits where they apply. Ask about our [drought-tolerant landscaping playbook](/blog/drought-tolerant-landscaping-ideas-san-diego/) for the plant-side of water-wise design.
