 Partially wooded with oak and locust trees, scattered pine forest and riparian woodland, approximately half of the park is agricultural, planted in grass and a stable cycle of cereal grains.In 1975 the nine municipalities established and funded a sanitation consortium, which constructed 30 km of sewer trunk lines to collect industrial and domestic wastewater and pipe it to a purification plant in Caronno Pertusella.The directors of the water purification project conceived the idea of a regional park in the area.
