It started with a car.
And a commitment.
The Green Park story began in Clark, New Jersey, in 1967.
Built here.
Grown here.
Robert Leo Sr. installed his first irrigation system out of the trunk of his car. Over the following decades, Green Park grew into a major New Jersey irrigation company, with more than 15,000 sprinkler systems installed throughout the state.
Our company history is a family story, with Robert Leo Jr. and Paul Leo joining their father in running the business. The umbrella man became a familiar symbol of quality and commitment to service.
From Toms River to Mahwah, our work has included residential, commercial, and municipal installations and service—even rooftop installations along the Hudson River.

A part of the New Jersey landscape.
Green Park works with dozens of landscapers and builders throughout northern and central New Jersey. Our customers span more than 150 municipalities across Union, Essex, Morris, Middlesex, Hudson, Passaic, Hunterdon, and Warren counties.
Our original company history describes the scale of that work: hundreds of irrigation systems installed each year, more than 10,000 sprinkler heads annually, and enough pipe in an average year to nearly stretch the 172-mile length of the Garden State Parkway.
Our earlier company overview also records Green Park’s installation of the largest residential sprinkler system in the United States.
Knowledge makes a difference.
We encourage customers to choose licensed irrigation contractors and make sure their contractor obtains the necessary permits. Proper permitting, inspection, and backflow prevention are essential parts of an installation.
Whether you need an estimate for a new system or service for an existing one, we’re ready to help.
