A Resilient Place

A Resilient Place is one that manages its resources in the most ecological way to cope with future changes – not least climate change. The site provides a real opportunity to invest in infrastructure and engineering expertise at scale and ensure the place is sustainable and resilient for future generations. The way energy is used and generated, water managed and people connected digitally is all critical to our thinking. But it is more than pipes and wires and the proposals reflect the way people live their lives, and allow capacity for new technologies to be added during the rollout and lifetime of the development.

We are committed to:

  • Reducing water and energy demands in the first place though the design and approach to construction.
  • Setting ambitious standards and targets for energy efficiency at each phase of development.
  • Fully exploring the site wide energy and district heating opportunities, with at least 10% on-site renewable energy generation.
  • Managing water efficiently and designing a sustainable drainage system which responds to the site and to local concerns about flooding and waste water.
  • Achieving the best digital connectivity possible.

 The proposals include:

 Water management

The vast majority of the Application Site is in the lowest risk area for flooding (Flood Zone 1) having a less than 1 in 1,000 annual probability of river or sea flooding (<0.1%) in any year.

 Surface Water:

The proposed surface water drainage strategy will mitigate the impact of the increase in impermeable area by the provision of ditch systems, which draw on the fenland tradition, and discharge to attenuation basins across the development. This will provide drainage system for a 1 in 100 year event, including an allowance for climate change projections.

Any excess beyond this will be managed away from development toward public open space and roads. As an additional measure floor levels will be set at least 150mm above surrounding ground level or 300mm above the area of the 1 in 100 year flood level. A buffer of 9m will also be ensured between any development and the top of Internal Drainage Board drains.

Utilities:

The Application provides for the provision and/or upgrade of services and utilities. Extensive surveys have allowed the team to develop a planned investment in local infrastructure which takes into account other planned development. The phased investment will support the new development and improve the local capacity, including:

Electricity – Landbeach primary substation to the north-west of the Site, with sufficient capacity to supply the Proposed Development. Three 11kV feeds from the substation to the Application Site will be supplied.

Gas – there is sufficient capacity in the local network to supply approximately 1000 residential units.  Beyond this level investment will be agrees with suppliers to reinforce the local network and reinforcement.

Potable Water – There is sufficient capacity available in the local network to supply approximately 1000 residential units. Beyond this, reinforcement/upgrade of the local network including a new main (4 kilometres in length) will be put in place to get the supply to Site from Cherry Hinton Reservoir.

Foul Water – A new Water Recycling Centre (WRC) will be required to accommodate the full development.  There is capacity in the Waterbeach WRC to accommodate around 570 units in addition to those already committed and the proposal for residential conversion of the Barrack Blocks for Papworth. Interim measures to secure additional capacity in advance of a new WRC are being explored, including accessing the Cambridge Research Park rising main.

Telecoms – BT Openreach have offered ‘Fibre to the Premises’ for the Proposed Development at a speed of 300mb.  Virgin Media infrastructure is also accessible providing opportunity for a dual network supply.

Further agreements with the Utility companies is not possible until the application is progressed through the planning system, and so the details of these will be formalised over the next few months.

Energy:

Two energy centres are proposed in general locations set out on the Parameter plan, on sites of up to 1,000 sqm each, including a storage area (up to 0.4 hectares in total). These are intended as facilities for local energy generation, employing low or zero carbon technologies. The precise technology to be used will be determined in further detailed studies and planning applications, to ensure the latest technological advances are considered. A range of options are set out in the Energy Strategy.

The strategy also commits the development to comply with Part L of the Building Regulations 2013 and exceed mandatory Fabric Energy Efficiency Standards (FEES); to drive a reduction in the amount of CO2 emitted per year by at least 10% compared to the minimum Building Regulation requirement; and BREEAM Excellent standards for non-residential buildings such as schools.

Additional Environmental Sensitivities will be supported through:

  • Lighting schemes will be deployed for each phase within built areas and along primary roads to minimise light spill and effects on surrounding countryside and ecology.
  • External lighting for outdoor playing fields will be designed to limit direct light illumination spill and glare obtrusions towards both local and more distant receptors.
  • Uses considered as sensitive to noise and air quality will not be located immediately adjacent to the A10 road or any energy centres and related infrastructure.
