BWB delivered a range of multi-disciplinary solutions that helped secure outline planning consent for 94 houses and a community centre in the Warwickshire village of Temple Herdewyke. We were commissioned by Lone Star Land Ltd to provide specialist transport, environment and infrastructure expertise in support of their planning application to Stratford-upon-Avon District Council.

The village itself is largely incorporated into part of a Ministry of Defence Storage and Distribution facility which posed particular challenges at the 3.9 hectare site. Our pre-planning inputs included designing a signal control crossing to facilitate safe access between the site and a local primary school and securing Environment Agency approval of our design of onsite package treatment works. We also designed a surface water drainage strategy in order to mitigate any potential flood impacts being caused to the wider area.

The proposed development was given the green light by Stratford-upon-Avon District Council's planning committee in late 2015.

Key Challenges

BWB's transport team demonstrated to the council's satisfaction that the proposed development would not have an adverse impact on the local highways infrastructure and addressed their concerns regarding access to a nearby primary school. Following our discussions with the local authority, we recommended a signal control crossing solution to link the school with the rest of the village.

Waste water drainage was an issue at the site as the nearest Severn Trent Water sewer was 1.2km away, making it unlikely that a gravity connection would be achievable. An on-site pumping station would usually be considered but the modest number of houses proposed meant that low flows could bring the potential for foul sewage septicity issues so it wasn't deemed a cost effective option. BWB's Infrastructure Management team designed an on-site package treatment works which treats the foul flow within the development and allows those treated flows into the surface water system. While this method is not usually favoured by the Environment Agency and was initially rejected, through our negotiations and discussions we were able to persuade them of the merits of our strategy and ultimately secure their approval.

Environment Agency Surface Water Flood Risk maps showed the site was at potential risk from a number of nearby watercourses and private surface water drainage systems. We undertook a hydrological analysis to estimate the likely flood flows which may be generated and by using hydraulic routing calculations we demonstrated that the site was not at a significant flood risk. We formulated a surface water drainage strategy which provided attenuated storage in the form of SuDS to mitigate the development's impact on the local hydrological regime and prevent a negative impact on flood risk in the wider area.
