Glil Yam Park

Glil Yam Park is a large area of about 200 dunams in Herzliya, north of Kibbutz Galil Yam, framed by new residential neighborhoods. In addition to leisure and community uses, the park is unique in that it includes the diversion of the Glilot Stream and the creation of extensive areas within the park for stormwater detention. The program required detention areas for about 35,000 cubic meters of water, leading to a dramatic topographical design. The stream runs through the center of the green area, creating a series of large pools with grassy slopes. During rainfall events, the stream’s water fills the pools and prevents flooding of the nearby train station. After a few days, the water seeps into the groundwater.

The rainy winters since the park opened to the public have highlighted the challenge of managing peak rainwater systems. The detention system has worked successfully, creating beautiful pools for the enjoyment of residents. The site exemplifies a successful attempt to address peak rainwater systems by detaining stormwater in open spaces within urban areas and proves that it is possible to harness detention to enhance active open space in the city.

The paths and active areas in the park are located on the higher margins on both sides of the stream, interwoven with play areas, unique shading structures, a challenging bike path, fitness facilities, and food zones. A wide pedestrian bridge connects the two parts of the park, with a gentle ascent that blends into the landscape. At this point, a water reservoir with a diameter of 50 meters is discreetly integrated in the topography for city use. A café has been built on the side of the reservoir, facing the active areas and enriching the space.
