The Challenge of SuDs on Small Sites

It’s the developer’s nightmare: a small site and the local authority wants Biodiversity net gain, plenty of green space, tree lined streets and now is looking for SuDs. Where are they going to put the buildings?

GreenBlue Urban are used to these difficulties; in fact we look at them as opportunities to showcase best collaborative design solutions where all of these challenges can be integrated without loss of developable land.

In a recent project in Chepstow, Wales, an integrated design led to a new development meeting all of the LPA requirements. An infill development, where space was at a premium and where the properties were designated as affordable, meant that careful use of space was critical.

Street trees in Arborflow treepits were used to provide the attenuation required, along with permeable paving and a small attenuation tank with orifice control ticking all of the boxes for the local authority;

  1. Full SuDS compliance
  2. Tree lined streets
  3. Added biodiversity – a net gain over the previous garage block use

This type of development is possible thanks to intelligent consideration of all of the options, and GreenBlue Urban worked closely with the developers Capsel Homes, who are the trading subsidiary of Monmouthshire Housing Association. The result is a pleasing development which is fully sustainable for generations to come.

A larger scheme that GreenBlue Urban were glad to work with was the development in Walton, Felixstowe in Suffolk. This highly regarded development was originally designed with large attenuation ponds to deal with the flood risk from surface water, but with the intervention of Suffolk County Council and the assistance of GreenBlue Urban, these ponds were replaced with street side HydroPlanter Rain Gardens giving an equivalent storage volume but without the sacrifice of space. The GreenBlue Urban ethos of ‘Micro-Suds’ really helped the developer to achieve better housing densities without the loss of SuDS provision.

The integration of green and blue infrastructure is simple but needs to be carefully considered. Sustainable drainage systems are just the mimicking of how nature deals with rainfall events transposed to work with site conditions. GreenBlue Urban has unrivalled experience in working with stakeholders to achieve maximum site efficiency as well as meeting legal and regulatory requirements.

Trottoirs soulevés, chaussées fissurées, surfaces piétonnes inégales : lorsque ces problèmes apparaissent autour d'arbres matures, les racines sont généralement pointées du doigt.

Les populations d'arbres urbains dans les villes du monde entier subissent de fortes pressions. Malgré les avantages manifestes qu'offrent les arbres, notamment le rafraîchissement des rues,

Lorsque l'expression « strangulation racinaire » est mentionnée lors d'une réunion de devis ou d'une discussion de planification, elle a tendance à figer net la conversation.

L'un des défis les plus importants auxquels l'industrie du verdissement urbain fait face aujourd'hui réside dans notre capacité à répondre efficacement à l'accélération du climat

Planter un arbre est souvent perçu comme un acte d'optimisme, un geste tourné vers un avenir plus vert et prometteur. Toutefois,

Concevoir des aménagements urbains qui soutiennent à la fois la saine croissance des arbres et les exigences structurelles des chaussées, des sentiers et des zones carrossables

En milieu urbain, le sol réunit rarement les conditions nécessaires à la croissance et à l'épanouissement des arbres. L'espace racinaire restreint, la compaction et les conflits d'usage

Nos systèmes de drainage urbain existants sont sollicités bien au-delà de leur capacité initiale de conception. La densification du développement,

Chaque hiver, les villes prennent un air plus festif. Les rues s'illuminent, les marchés s'installent et, sur de nombreuses places publiques,

Les milieux urbains sont des espaces complexes et très sollicités où chaque centimètre carré de terrain remplit une fonction. Pourtant, même dans les zones à forte densité bâtie,
