Central Coast Landscaping
Drip irrigation in Los Osos puts water at the root zone instead of onto pavement, cutting waste and keeping you inside San Luis Obispo's watering-day rules. Kestrel Landscapes audits your existing system, converts thirsty spray zones to drip, and programs a smart controller to your agency's allowed days and times.
Most of the water a Central Coast landscape wastes never reaches a root. Overspray onto pavement, a stuck valve, a controller running lawn and shrubs on the same schedule — small faults that add up to a big bill and a garden that's simultaneously over- and under-watered.
Kestrel Landscapes designs, installs, audits and repairs irrigation built around how you're actually allowed to water in San Luis Obispo — odd/even day schedules and the no-watering 10am–4pm window. We convert thirsty spray zones to targeted drip, put a smart controller in charge, and set it up so it holds water at the roots.
Time for an audit or upgrade when you see:
We swap overspray-prone spray zones for drip and micro-emitters that deliver water directly to the root zone — far less evaporation, far less runoff, and healthier plants that aren't getting their leaves wet in the fog.
Weather-based controllers adjust to the season automatically and can be set to honor odd/even day and time-of-day rules. Paired with proper hydrozones, lawn, natives and new plantings finally get schedules that fit each one.
We inspect valves, heads, emitters, pressure and coverage, find leaks and overspray, and program the controller for establishment, then hand off a seasonal adjustment plan. Great before summer and after any planting change.
We photograph and test valves, heads, emitters, pressure and coverage, and flag leaks and overspray.
We group plants into practical hydrozones by water need, exposure and soil.
We convert spray to drip, replace failed components, and set a smart controller.
The controller is programmed for establishment and set to respect odd/even and 10am–4pm watering rules.
We recheck after planting and before peak summer demand, and document the adjustment plan.

Irrigation work ranges from a targeted repair to a full system. Drip conversions and controller upgrades are priced by number of zones and system condition; a small repair is far less than a whole-yard rebuild.
Note: We won't claim a guaranteed savings percentage without measuring your specific system — but drip plus smart scheduling reliably cuts waste.
We program weather-based controllers to your provider's odd/even day and no-10am–4pm schedule, so efficiency and compliance are built in, not left to chance.
We check valves, heads, emitters, pressure and coverage and keep what works, rather than ripping out a system that mostly does its job.
Lawn, natives, edible beds and new plantings get schedules that fit each one — the fastest way to cut an unexplained water bill.
We recheck the system after planting and before peak summer demand, and hand off a seasonal adjustment plan in writing.
Many Central Coast agencies limit landscape watering to assigned days (often odd/even by address) and prohibit watering during the heat of the day, commonly 10am–4pm. Rules vary by agency and drought stage, so we program your controller to your provider's current schedule and confirm it before handoff.
For beds and shrubs, yes — drip puts water at the root zone with almost no evaporation or overspray, which matters in our fog and wind. Lawn and large groundcover areas may still use efficient rotary heads. We match the method to the plants.
It's a full check of valves, heads, emitters, pressure, coverage and controller programming to find leaks, overspray and waste. It's the fastest way to cut an unexplained water bill and is worth doing every spring.
It helps — weather-based controllers can be set to your agency's allowed days and times and adjust automatically as seasons change, so you're not manually chasing the rules.
Usually, yes. We start with an audit of your current valves, heads, emitters, pressure and controller, then repair and convert what's worth keeping instead of ripping out a system that mostly works. Where the old layout can't be made efficient, we'll tell you honestly and price both options.
We're based in Los Osos and bring irrigation & drip to homeowners across the Central Coast — the back-bay and coastal towns of Los Osos, Morro Bay and Cayucos, the city of San Luis Obispo, the Five Cities, and the North County wine country around Paso Robles.
