• Related project on Forest Road: over 600m² rain gardens, 30 Hornbeam and Carpinus Fontaine trees, 10,000+ plants including grasses, Iris, Lavender, Rosemary, and Sage.
• Forest Road enhancements target flooding, create wildlife corridors, act as green barriers next to cycle lanes, filter pollutants, and support active travel.

Waltham Forest (East London Times) April 21, 2026 – A once treeless, vehicle-dominated street has undergone a major green overhaul, introducing rain gardens, widened footways, and tree planting to combat flooding and boost biodiversity.

What Triggered the Transformation of Sutherland Road?

The initiative addressed Sutherland Road’s history as a treeless stretch for more than 100 years, dominated by vehicles and prone to surface water flooding. Waltham Forest Council implemented the project to enhance climate resilience and create a more accessible community space.

As stated by Waltham Forest Council, the biodiverse planted areas will improve air quality, reduce surface water flooding, improve urban cooling, and provide new habitats for pollinators and urban wildlife.

The public realm project involved collaboration with Meristem Design, Riney, Wavin Orbia, and what:if. Meristem Design notes that Sutherland Road now boasts the longest continuous residential rain garden in the UK, spanning 500 metres with around 500 square metres of rain gardens and permeable paving, plus about 500 square metres of footway, 68 street trees, and 300 shrubs.

Funding sources included the Greater London Authority (GLA), the Community Infrastructure Levy, Section 106 agreements with developers, and direct council investment. This aligns with the GLA’s vision for the Blackhorse Lane Creative Enterprise Zone, fostering a more vibrant community space.

Which Improvements Were Made to Infrastructure and Safety?

Improvement works encompassed carriageway and junction enhancements to provide more space for walking and cycling. New and upgraded CCTV cameras were installed for security. Mill Gardens green space also received upgrades.

Parking spaces were removed from the kerbside adjacent to the affordable Sutherland Road housing scheme, which has low car ownership. As reported by Meristem Design,

“Addressing historical flooding issues necessitated innovative design solutions and the integration of SuDS. Ensuring widespread understanding and support for the changes was critical to the project’s success.”

Meristem Design further explains,

“The removal of parking spaces to accommodate the rain gardens required clear communication and collaboration with local residents and businesses. The project required creative design that had a balance of green infrastructure within a narrow, vehicle-heavy street.”

How Did Public Art Contribute to the Project?

Public art features prominently, led by what:if and involving young people from Blackhorse Workshop’s Responders and Make Stuff Club programmes. Inspired by the plants in the rain gardens, participants created hybrid flower designs by combining botanical elements, resulting in ‘Flowers of Sutherland Road’. These designs were translated into artworks installed on metal shutters along industrial units on the street.

What Is Meristem Design’s Assessment of the Project?

Meristem Design states,

“The transformation of Sutherland Road sets a precedent for similar green transformations in other residential areas, promoting healthier, more liveable streets across London.”

They add,

“By reclaiming space for nature and people rather than vehicles, the revitalisation of the street encourages walking, cycling and social interaction while enhancing the look and appeal of the neighbourhood.”

Why Was a Similar Scheme Implemented on Forest Road?

Not far from Sutherland Road, Meristem Design has planted rain gardens along a section of Forest Road between Blackhorse Road and Tottenham Hale.

This section now includes over 600m² of rain gardens on both sides, home to 30 narrow-forming Hornbeam trees, Carpinus Fontaine trees, and over 10,000 plants such as grasses, Iris, Lavender, and herbs including Rosemary and Sage. These plants are hardier and require less maintenance than those on Sutherland Road.

Meristem Design says,

“The sustainable green solution filters urban pollutants and allows for more controlled and effective surface water management. By improving the drainage along the stretch of road has transformed Forest Road into a functional and vibrant space.”

The road is flanked by Walthamstow Wetlands, Europe’s largest urban wetland nature reserve, spanning over 500 acres with ten reservoirs. The project’s rain gardens run between the footway and segregated cycle lanes.

What Benefits Do Forest Road Rain Gardens Provide?

Meristem Design notes,

“The rain gardens are also used as a wildlife corridor and biodiversity booster. Used next to a cycle lane, the SuDS create a green barrier between vehicles, pedestrians and cyclists, helping to improve air quality, soften traffic noise and encourage more active travel.”

They add,

“The main benefits have been to target and improve both roads and homes that are known to flood. The greenery not only boosts the quality of public space but also offers an ecological sanctuary, contributing to Waltham Forest’s sustainability goals.”

This project, like Sutherland Road, demonstrates a practical application of SuDS in urban settings, integrating green infrastructure to manage water, enhance biodiversity, and support sustainable transport.

Background of the Development

Waltham Forest has pursued green and blue infrastructure initiatives as part of broader sustainability efforts. Sustainable Drainage Systems (SuDS) form a key element, working alongside natural water features like the borough’s rivers and wetlands.

Walthamstow Wetlands provides a significant ecological backdrop, influencing projects like those on Forest Road.

Meristem Design’s involvement spans multiple sites, focusing on flood-prone areas. Historical vehicle dominance and impermeable surfaces in these streets prompted the shift towards nature-based solutions. Funding mechanisms such as GLA grants and developer contributions have enabled scaling these interventions.

The projects build on Waltham Forest Council’s strategy to integrate SuDS into public realms, addressing urban challenges like flooding exacerbated by climate change.

Prediction: How This Affects Waltham Forest Residents

Residents in Waltham Forest, particularly those in flood-prone areas like Sutherland Road and Forest Road, may experience fewer flooding incidents due to the SuDS managing surface water runoff. Improved air quality and urban cooling from the trees and shrubs could lower health risks associated with pollution and heat.

The widened footways, cycle lanes, and green barriers may increase walking and cycling, offering safer routes separated from traffic. Low car ownership households near the removed parking spaces might see minimal disruption, while the added greenery enhances neighbourhood aesthetics and encourages outdoor activity.
