Watercolour green infrastructure strategy plan for an exemplar area in north west Bicester: SuDS attenuation ponds, riparian corridor, allotments, orchards and housing around a lake

BicesterMasterplanApplication

The landscape strategy applies eco-town principles to the proposed development at north west Bicester. It combines public realm, water management (SUDs) and habitat protection within a connected green infrastructure network. The exemplar area demonstrates this approach through the relationship between development edges, a retained riparian corridor and adjoining open spaces.

Contribution
Researched green infrastructure strategies, supported the project graphics and developed the exemplar area as the basis for the wider landscape concept.
A tree with its roots below ground: urban benefits of green infrastructure Benefits: pocket park, colourful seasonal displays, cooling, enhanced walkability, stormwater attenuation, sense of place, landmarks, enhanced well being, community food growing, muffled street noise, building energy saving, property value uplift, sustainable urban drainage, biodiversity, air quality, urban orchard

Concept

Urban benefits

Green infrastructure provides the environmental and social framework for the development, combining biodiversity, water management and public amenity within a multifunctional landscape.

Space to …

The concept responds to people’s need for space to breathe, move, connect, grow, learn, play and share, translating these needs into the provision and character of open spaces.

Analysis

A place divided

The relationship between existing and proposed development highlights the need for connections across their boundaries.

Space to … live!

Shared landscape spaces provide the basis for integrating the new development with its surroundings.

A place united

A connected landscape links the existing and proposed communities through shared routes and public spaces.

Key plan

The exemplar area within the wider masterplan.

Exemplar site masterplan

The retained riparian corridor and hedgerows form the ecological framework, with attenuation ponds and habitat scrapes integrated into adjoining open spaces. Allotments, orchards and recreation areas occupy the development edges, maintaining open views towards the water and landscape.

Community and pedestrian routes

The community route connects development areas and shared amenities, while secondary footpaths provide access through the open spaces alongside the protected riparian corridor.

Section G–G

Section H–H

The residential frontage overlooks recreation and play space, with the attenuation pond beyond.

Design development

The green leisure loop for cyclists and pedestrians

A continuous route links recreation areas and open spaces, with dedicated paths for walking and cycling.

Walk

Cycle

Planting divider

A planted verge separates the footpath from the cycleway.

Breakout spaces and views out

Rest areas along the route provide places to pause, with views across the surrounding countryside.

Typical edge treatment near settlements: zones from agriculture, edges and wild zone to activity zones and settlement, with woodland, footpaths, allotments and orchards
Section X–X: agriculture, woodland, footpath, wild zone, allotments and orchards, community route, play area and settlement

Design development

Defining the edges

The boundary treatment creates a transition from residential development to agricultural land, combining active uses near the settlement with woodland and less intensively managed habitats beyond.

Section X–X

Allotments and orchards sit between recreation areas and woodland, balancing outward views with screening from the surrounding countryside.

Typical section across the water channel: buffer zones either side of the riparian corridor, 30 m either side of the water channel
Typical section across a hedgerow buffer zone: minimum 10 m either side of the existing hedgerow, with a swale and footpath

Design development

Biodiversity strategies

Typical section across water channel

The existing riparian corridor is retained without changes to its levels or vegetation. Adjacent buffers accommodate a mosaic of habitats, with footpaths and sustainable drainage features outside the protected corridor.

Biodiversity strategies

Typical section across hedgerow buffer zone

The existing hedgerow is retained within a planted buffer, protecting its habitat value and continuity through the development.
