A gravel path through deep, settled planting in a park ten years after it opened.

A park is judged on its opening day and lived in for decades. The gap between those two facts is where most public landscapes quietly fail.

What we compared

We revisited eight projects, all between nine and fourteen years old, and lined up their construction budgets against whatever stewardship funding survived after the ribbon cutting.

What made the difference

The projects that still look and work like their drawings share one thing: a modest annual budget, usually one to two percent of construction cost, with someone named as responsible for spending it. Better paving, thicker steel and larger tree stock made far less difference.

Where that budget did not exist, the same pattern repeated: invasive species returned in year three, understory planting thinned by year five, and by year eight the landscape needed capital works again.

What we now ask for

We write a stewardship plan into every project, with a first-decade cost estimate, and we say plainly which parts of the design depend on it. If the money is not there, we simplify the design rather than hope.
