Spanning over 32000 square meters and featuring a landscaped rainwater catchment basin [5], the Rain Garden was created in 2014 in the Nuvali district of Santa Rosa. The garden offers an example of eco-friendly urban planning in the Philippines, as the Nuvali district is an eco-city itself with residential, business and commercial areas. Besides the Evozone Rain Garden, Nuvali also has various nature amenities, including a multi-functional lake, cycling and hiking paths, a wildlife and bird sanctuary and camping grounds. The Evozone Rain Garden was established in a commercial development area and it includes spacious open areas and cycling paths, along with the footbridge and view deck and adjacent to the manmade lake in Nuvali [2]. The Rain garden also serves as a rainwater catchment basin, rainwater harvesting system, and fire reserve, providing recycled water for landscaping, irrigation and other non-potable water uses [1]. In addition, the garden has been developed to serve as a habitat for various bamboo varieties and birds [4], also making the garden an ideal birdwatching spot [3]. The EvoZone Rain garden is free and open to the public [2].

Project objectives

The Evozone rain-garden project had the following objectives: - serve as a rainwater catchment basin made from a natural plant-based filtration system and sand and stones to form a landscape area [2,5] - help with rainwater harvesting, serve as a fire reserve and provide recycled water for landscaping irrigation and other uses which do not require potable water [1] - accommodate visitors and nature lovers who are looking for an escape from urban life [2] - serve as a habitat for bamboo varieties, and birds [4] - serve as a birdwatching area [4]

Implementation activities

The garden has an all-natural plant-based filtration system to capture rainwater. In addition, sand and stones were utilized to form a picturesque landscape area [5], and 20 bamboo varieties and seven types of trees were planted. [4]. Additionally, the developer of the area created spacious open areas, walking, jogging and cycling paths that encompass the garden. A footbridge has also been constructed to offer a vantage point to view the natural areas of Evozone. A view deck was added so that visitors can engage in bird watching and enjoy the sights and refreshing breeze [2]. The garden provides a home to at least six species of birds, which has made this zone a birdwatching spot. [4]
