In planning stage

Pollution from roadways is often carried by rainwater into gullies, which then direct this runoff to the nearest watercourse, ultimately polluting local rivers and degrading water quality (1). To address this issue, Dublin City Council is exploring potential green infrastructure solutions to reduce roadway pollution in rivers, focusing on nine pilot sites within the Dodder catchment area (1). Green infrastructure has the advantage of treating pollutants before they enter rivers or watercourses, which can significantly improve water quality in the area (1).
In addition to enhancing water quality, green infrastructure helps manage flood risks by slowing water flow to rivers, which can lessen the frequency and severity of flood events (1). These green spaces also foster biodiversity, creating more pleasant and ecologically supportive environments for the community (1). As an added benefit, green infrastructure serves as an important climate change adaptation strategy (1).
Upon completion of these pilots, Dublin City Council plans to expand successful methods to other locations across the city and potentially further afield (1). The project will involve creating new green spaces, enhancing existing ones, and transforming certain hard surfaces, all of which will contribute to protecting the Dodder and Santry rivers. By treating roadway runoff before it reaches the rivers, the initiative will also offer valuable benefits to the local community (2).
The proposed changes will be designed to support health and well-being, provide informal play areas, attract desirable wildlife, reduce flood risks, and help urban areas adapt to the impacts of climate change (2). The Council also plans to monitor the performance of these green infrastructure measures to assess their effectiveness in filtering pollutants from roadway runoff (1).

For thousands of years the Rio Salado, also known as the Salt River, and its larger mainstem, the Gila River, served as an important perennial source of life and growth for indigenous people residing in central Arizona, including the Akimel and Piipaash (3). Today, the Salt River is an ephemeral river corridor connecting diverse urban communities across an expansive and growing Maricopa County (3). While the river is now typically defined by intermittent flow as a function of water conservation and distribution in an arid urban climate, it also has powerful flows during the Arizona monsoon season providing a diverse and unique ecosystem for the region (3). To foster the health of the River, a regional multi-decade project was initiated in 2018 called Rio Reimagined, which includes six cities and two tribal communities (1). Rio Reimagined is a planning initiative in a very early concept stage, centered around the mission to support and enhance this treasured river corridor (3). The goals of Rio Reimagined consist of connecting communities, Equitable & Sustainable Development, and Restoring and Revitalizing Healthy Rivers (3). As part of the Rio Reimagined, the City of Phoenix founded a collaborative project called Rio PHX that will help promote a 20-mile Rio Salado (Salt River) corridor as a local and regional destination that attracts positive investment for the benefit of existing/future businesses, residents, and tourists (1). The final aim with this project is to improve health outcomes for existing and future residents by address outstanding needs in the area and create opportunities for housing, employment, recreation, art, and ecological restoration (1). From May 2024 to May 2025 Rio PHX will engage in creating a community profile, an existing conditions assessment, community engagement & visioning, developing implementation strategies and drafting the master plan (1). Public hearings and final plan adoption are set to take place in fall 2025 (1).

The Rimac River Special Landscape Project, developed by the Municipal Programme for the Recovery of the Historic Centre of Lima (PROLIMA), is a municipal proposal that arose as a response to the significant degradation of the Rimac River as it passes through the historic centre of the Peruvian capital. The river has lost its character as a green corridor and potential public recreational space for citizens (1, 3). The main problems affecting the river are related to the erosion and risk of flooding of the river space, the ecological degradation of its channels and banks, the disconnection and low quality of adjacent public spaces and the urban fragmentation caused by car-oriented mobility (2). To recover its essence as an ecological green corridor, it was proposed to give back to the Historical Centre its riverside identity and to recover the water, environmental and scenic landscape. This project aims to restore the Rímac to its role as a geographical heritage and backbone of the city of Lima, creating a system of accessible and sustainable public spaces that will help to recover this water, urban and historical landscape, as well as providing a better quality of life for the residents and users of the Historical Centre (1).
The project consists of 4 stages of intervention: Puente del Ejército - Puente Santa Rosa / Puente Santa Rosa - Puente Balta / Puente Balta - Límite
of the CHL to the east (5). Among the interventions that make up the Special River Landscape Project are: the renaturation of the 4 km of the Rimac River as it passes through the city, the construction of 14 parks, 7 squares, 1 tree planting project, 24 street renovation projects, 7 bridges/pedestrian walkways, 10 building rehabilitations and 2 new public facilities (4). It is planned to start implementing the project by the end of 2024 (4).

A new landscape plan for the Santry River, developed since 2019, envisions it as “the backbone of a green infrastructure project,” designed to support nature, pedestrians, and cyclists. The project will create a continuous route from the Dublin Bay Biosphere at St Anne’s Park to the wider hinterlands of Dublin at Sillogue.
The plan proposes transforming the Santry River into an “integrated green-blue landscape for ecology and recreation,” incorporating a variety of sports, cultural, and leisure activities. Through an agreement with Fingal County Council and the National Transport Authority, Dublin City Council has commissioned studies to address the existing flood risks along the river.
The council’s goals for the Santry River include river restoration, flood mitigation, greenway development, and environmental protection, extending from the river’s origin in Harristown within Fingal County to its outlet at James Larkin Road. The project framework will span four years, with annual reviews and budget assessments.
The project team has engaged the public in early autumn of 2022 to gather input on these plans, as the Santry River project aims to create a vibrant River Park that integrates natural and recreational elements. Running through North Dublin, this new green-blue infrastructure will serve both ecological and community needs, offering opportunities for sports, culture, and relaxation. Ultimately, it will form a natural corridor linking the Dublin Bay Biosphere at St Anne’s Park with Sillogue, promoting biodiversity while enhancing accessibility for pedestrians and cyclists (2).

A new park is being planned for the Cypress Shores area in Mobile (Ref 1). Five civil engineering students from the University of South Alabama contributed to the design of the park (Ref 1). This collaboration offers students practical experience while providing city designers with innovative ideas for the site (Ref 2). The design emphasizes sustainability and cost-effectiveness (Ref 3). The project will feature a small park and boat launch on a 5.6-acre plot (Ref 1) located within a residential neighbourhood (Ref 3).
The park's societal goal is to improve public access to Halls Mill Creek, giving the community a new way to enjoy the waterway, and this focus aligns with the Mobile Bay National Estuary Program (MBNEP) goals (Ref 3). Historically, the property was used as a shipyard with a nearby railroad crossing (Ref 1), marking its transition from an industrial site to a public park.
Several amenities have been identified for the park’s development, including a boat ramp and kayak launch, a boardwalk adapted to sea-level rise, a pavilion and gazebo designed for flood resilience, a wetland nature trail with solar lighting and educational signage, and composting toilet restroom facilities (Ref 3). An armoured shoreline will be implemented to withstand medium water currents, and wave action will be constructed. Additionally, a living shoreline will be restored with local plants (Ref 3). While the project is still in its preliminary design phase, the timeline for completion is estimated at 12 to 18 months (Ref 1). The designers highlighted a potential trade-off, noting that an influx of visitors to the park could disturb the surrounding residential area (Ref 3).

Masthuggsparken is a planned park in the Masthuggskajen district, which is undergoing development and construction. The park will measure about 2000 m2, and serve as a green oasis and meeting place for locals. It will have ameneties such as benches and areas for play, and a noise barrier against a large nearby road. The park will connect to the adjacent square and street, making it accessible to visit. The street will be renovated to have more trees and plants, increasing green connectivity in the district. The park will be surrounded by trees and other plants, which are planted to promote biodiversity and be adapted to a changing climate [Ref. 1-5, 7]. The park is at a low point, where up to 800 m3 of stormwater will flow during heavy rainfall, reducing flood risk in the surroundings [Ref. 1, 2, 6]. The Masthuggskajen district has a sustainability program, establishing goals for green environments which the park will contribute to. Green areas should be accessible to the entire district and provide ecosystem services such as rainwater management, climate adaptation, biodiversity and recreation. The program was created by the City of Gothenburg in collaboration with construction companies active in the area and was supported by Citylab Action, a national competence program in sustainable urban development [Ref. 7]. The City of Gothenburg is the primary responsible for the park, which will be constructed between 2025 and 2026 [Ref. 1, 2, 4].

The Horpaz-Ezareni Park is an initiative driven by civil society, requesting the municipality of Miroslava to construct a natural park adjacent to Lake Ezareni. The aim is to protect its green spaces and aquatic bird species while addressing waste management in the area. The petition also called for more green spaces in line with European standards and sought to tackle the challenges of rapid urbanization in peri-urban areas. It collected hundreds of signatures and targeted an area of 20 hectares.
In response, the municipality agreed to the petition and initially proposed creating a park covering 4 hectares in 2022. This first plan was released to the public for consultation. However, the project has since evolved to encompass the original 20 hectares, plus an additional 2 hectares, with an estimated project cost of 11,000,000 euros and a timeline of 3 years for implementation.
The park's design includes various facilities and amenities aimed at enhancing opportunities for recreation, exercise, and relaxation. Accessible paths for pedestrians and cyclists, as well as a parking lot, are also part of the plan. Additionally, two buildings are proposed for sanitary and administrative purposes, which would manage the projected installations of a lighting system, Wi-Fi, and surveillance cameras.
Environmentally, the project includes plans for managing the lake's banks to remove hydrophilic vegetation that could create an unhealthy environment, along with the construction of two bridges. The wilderness areas will be managed, and dendrological plants will be introduced to improve the ecosystem's quality. Overall, the project aims to increase and regenerate green spaces in the commune, enhancing the quality of life for residents and improving the area's aesthetic appeal. (1-8)

The last large-scale park in Iași was opened in 1923, and since then, the city has lacked any significant new green spaces. With the European Union recommending at least 26 square meters of green space per resident and the city's increasing urban density, the need for a new park is undeniable.
To address this, the Municipality of Iași is launching its first major park project in over a century. The project aims to transform the current CTP depot (tram station) into a 4.5-hectare, accessible green space in a densely populated area with strong development potential. This new park is envisioned as a green oasis that will enhance residents' quality of life while promoting environmental sustainability and urban renewal.
The initiative has received widespread public support, with citizens proposing the creation of a local museum to honor the tram station’s historical significance—one of the oldest in the city, with over 100 years of history. A consultation process has been established, involving local residents, NGOs, and a group of experts, including urban planners, architects, and mobility and environment officials, all contributing to the planning stage. Public suggestions for the park include underground parking, recreational and exercise facilities, and a diverse range of vegetation. Ensuring accessibility for all citizens and visitors is also a key priority in the park's design.
The municipality has allocated 300,000 euros for a solutions contest to finalize the approach to redeveloping the tram station. (1, 2, 3, 4, 5, 8, 9)

The municipality of Ciudad Juarez, in collaboration with UN-Habitat, has drafted a redevelopment strategy for an area known as "Paso de Oñate." This intervention falls within the broader framework of "Vision Ciudad Juarez 2040." The plan involves constructing a forested green belt along the southern edge of the Rio Grande (/Bravo) in the northwest part of Juarez, bordering the USA.
Currently in the planning stage, the project aims to restore the ecological function of various degraded areas along the Rio Grande, transforming them into a continuous, green, walkable, and recreational space. The strategy includes allowing vegetation to recover, introducing native plant species, and increasing tree cover to rehabilitate unmaintained parks, derelict areas, and degraded riverbanks. These areas will be equipped with new features and integrated with existing parks, schools, and playgrounds. The envisioned green corridor will enhance walking conditions, improve the perception of safety, offer recreational opportunities for all age groups, and deliver valuable ecosystem services such as temperature regulation, improved air quality, and water retention.
In addition to its ecological goals, the project has a historical and geographical dimension. It aims to incorporate cultural heritage elements, such as the monument of the New Citizen, Paso de Oñate, Turtles Park, and the beginning of the Acequia Madre. It will also connect with other green space initiatives, including the Mega Park "El Chamizal" and the "Corredor Cultural," which runs through the city center.
This intervention is being prioritized due to the area's ongoing social and ecological decline. Paso de Oñate is a critical border crossing point, which negatively affects mobility and air quality. The area also suffers from a high concentration of vacant housing, which contributes to the residents' perception of insecurity. (Ref. 1, 2, 3, 4)

In the city of Ciudad Juárez, the municipality, in collaboration with UN-Habitat, aims to design and create a park that encompasses the yards and unmaintained areas surrounding the railway station, transforming these spaces into an accessible and safe public area. This project covers over 500,000 square meters and addresses not only degraded areas but also several public squares. Described as "a coordinated urban recycling strategy," this initiative seeks to repurpose existing public squares and rehabilitate neglected spaces into vibrant green areas that feature universal accessibility, native vegetation, and urban furniture designed to enhance safety. The project also aims to provide increased recreational opportunities, improve permeability, and introduce additional shaded areas. A key component of improving permeability involves the restoration and incorporation of acequias—traditional historical irrigation systems that absorb and manage excess rainwater, thereby reducing the likelihood of flash floods.
Additionally, the project focuses on the restoration and promotion of significant historical buildings, such as the old railway station and the whiskey factory, integrating them into a larger cultural and sports facility area at the municipal scale. The overarching goal is to revitalize the site through effective coordination with the relevant authorities responsible for the spaces adjacent to the railway station, stretching from Plaza Misión de Guadalupe to Blvd. Municipio Libre. This collaborative effort aims to accommodate both sports and cultural facilities while also creating a green corridor.
Furthermore, the project intends to reforest, redesign, and enhance Plaza Misión de Guadalupe, Plaza Monumento a Benito Juárez, and other residual public spaces and gardens. This initiative aligns with its Public Space Strategy, which emphasizes the development of gender-inclusive and resilient public spaces.(Ref 1, 3, 4).
