Months before this project had gotten underway I asked the irrigation contractor to meet with me on the site to review the landscape plan.
This meeting is the first critical step in planning an automatic sprinkler system that is customized to the planting plan as well as to the unique characteristics of the site.
The contractor and I spent almost 2 hrs. together discussing each aspect of the design.
We consider the exposure, grades and plant types of each area, and then mutually agree on an irrigation strategy. From there an irrigation plan is drawn for the project and a budget prepared.
The irrigation contractor and I both know that there will be modifications to the irrigation design once the project is far enough along and the irrigation phase begins.
It’s the preliminary discussions a landscape designer has with the irrigation contractor, along with the changes made while the system is being installed that makes for a truly “site-specific” and efficient automatic sprinkler system.
Of all the things to consider when planning an irrigation system, there is one key point: Always separate the lawn sprinkler zones from the planting area zones.
This is because lawns require a different amount of watering from plantings. It all comes down to control.
In the top pic you’ll see one of three manifolds being built. This particular one has 4 valves – each of which controls a sprinkler zone.
These manifolds are built below grade (ground level) and are housed in plastic valve boxes with covers for access.
This project has a total of 14 valves (zones) and they are divided almost evenly between lawn zones and planting zones.
In the second picture a technician is installing a sprinkler head for a lawn zone. Notice he’s working in front of the plantings where he’ll position the head.
When installed, the coverage of the head can be adjusted to only water up to the grass edges and not the nearby planting areas.
Here’s the previous post for this project. And here’s the next.

Landscapes are complex, and shortcomings anywhere in the process can affect the project… and your peace of mind.
My approach is process-oriented. I break things down from planning to implementation — and make sure everyone is kept informed.
My goal is to alleviate concerns such as design decisions, costs, workmanship and material quality. I want folks to stress less and actually enjoy the process.
