How are irrigation zones determined during the design phase?

Zones are defined by plant type and water requirement, sun and shade exposure, and the type of delivery head being used—separating turf from drip zones ensures each area receives water at a rate appropriate to how quickly that soil and plant type can absorb it without runoff.

What causes dry patches in an otherwise irrigated lawn?

Head spacing that leaves gaps in throw radius coverage, heads that have shifted or settled out of level, or rotors with clogged filters that reduce output are the most common mechanical causes—in Hanford's alkaline water conditions, mineral buildup in small-orifice emitters and spray heads accelerates faster than in regions with softer water supply.

Why does water pressure matter for irrigation system performance?

Spray heads and rotors are rated for specific operating pressures; running above that range causes misting that drifts rather than landing at the intended location, and running below it reduces throw radius so heads don't cover the area they were designed to reach.

When should irrigation be installed relative to new turf or planting?

Irrigation infrastructure—mainline, laterals, and valves—should be installed before turf is laid or planting beds are established so pipe runs don't require disturbing root zones or finished surfaces; head placement can be finalized and adjusted once the planting plan is confirmed.

How does a smart controller differ from a standard timer in the Central Valley climate?

A smart controller uses local weather data and evapotranspiration rates to adjust run times automatically, which means the system runs less after cool periods and compensates during heat spikes rather than applying the same schedule regardless of conditions—this is particularly relevant in a climate where summer temperature variance between days can exceed 20 degrees.

Irrigation Systems | AAA Landscape and Pools

Hanford's summers deliver sustained heat with minimal natural rainfall from late spring through early fall, which means any planted landscape—turf, ornamental beds, or new installations—depends entirely on a functioning irrigation system to survive that window. Drought-stressed turf recovers slowly, and planting beds that dry out mid-season lose establishment progress that took months to build. AAA Landscape and Pools designs and installs irrigation systems as an integrated part of the landscape plan, with coverage zones, head placement, and run times matched to what's actually planted and how each area of the yard is used rather than applying a single zone layout across the whole property.

Irrigation layout decisions start with separating the property into hydrozones—areas grouped by plant type, sun exposure, and water need. Turf areas require different precipitation rates and run times than ornamental shrub beds, and newly installed plants typically need more frequent, shorter cycles during establishment than mature plantings do. Rotor heads, spray heads, and drip emitters all apply water at different rates and radii, and selecting the right delivery type for each zone prevents both underwatering and overspray onto hardscape, structures, or areas that don't need irrigation. In the Central Valley, overspray onto concrete and paving also accelerates surface staining and can contribute to moisture issues at foundations if head placement isn't reviewed carefully.

Request an irrigation consultation to review your current system's coverage, identify gaps or inefficiencies, and discuss how irrigation should be structured for any new landscape areas you're planning.

A well-designed irrigation system installation begins with mapping the property's planting plan and identifying coverage gaps, overlap areas, and any grade changes that affect how water distributes across a zone. Pressure regulation is a technical consideration that affects performance across the entire system—heads and emitters are designed to operate within specific pressure ranges, and a system running above that range produces misting and drift rather than targeted delivery, while one running below produces inadequate throw radius and uneven coverage. Smart controllers that adjust run times based on weather data and soil moisture readings are increasingly standard on new installations because manual scheduling rarely accounts for temperature swings across a Central Valley season.

After an irrigation system is installed or updated, the most immediate observable change is that manual watering stops being necessary and landscape areas that were showing stress begin to stabilize. Turf color becomes more consistent across the lawn rather than showing dry patches between head locations. Planting beds maintain soil moisture between cycles, which reduces transplant shock in new installations and supports steady growth through the summer. AAA Landscape and Pools sizes and places irrigation components to match the landscape plan so coverage works from the first run rather than requiring extensive adjustment after installation.

Irrigation systems installed alongside new landscape features—turf, planting, hardscape, or pool surrounds—benefit from being planned before other installation work is complete, since mainline and lateral runs are easier to route when landscape beds aren't yet planted and hardscape surfaces aren't yet poured. Retrofitting irrigation into a finished landscape requires working around established root systems, cutting through hardscape, and managing existing plant material during installation, which increases labor and limits routing options. When irrigation is part of a larger project scope, AAA Landscape and Pools sequences the work so pipe runs are completed before surface finishes go in..
