We are working on various aspects of the new masterplan for the city centre of Preston, Lancashire. The area concerned is known as Heart of the Tithebarn Regeneration Area (HTRA) and covers approximately 14.8 hectares. The masterplan provides for 32 new-build blocks, the refurbishment of existing structures, relocation of the bus station and a considerable area of new retail space, leisure facilities, public spaces and car parking.
Among the key environmental aspects considered during the evolution of the scheme have been land quality, archaeology, ecology (there are bats on the site), noise impacts, air quality, microclimate, drainage, townscape, visual context and waste management. Impact on the local economy and social structure have also been studied.
Our consultants undertook preliminary microclimate analysis of daylight, sunlight and wind flow on the development site and the surrounding area. The objective of the wind flow analysis was to ensure that the proposals offered a year-round comfortable external environment.
Our infrastructure engineers have completed an extensive 3D earthworks model of the proposed new bus station area that optimises the cut and fill volumes. A comprehensive drainage strategy has been developed that minimises the need for sewer diversion. The surface water strategy endorses the use of Sustainable Drainages Systems (SUDS) and includes rainwater harvesting, porous paving and the extensive use of green/brown roofs.
environmental impact assessment - EIA
As part of their work informing the masterplan development for the city centre of Preston, our environmental consultants coordinated an environmental impact assessment (EIA) for the project's planning submission. The site covers approximately 14.8 hectares and the masterplan provides for new-build blocks, extensive refurbishment work, relocation of the bus station and new retail space, leisure facilities, public spaces and car parking.
A comprehensive scoping study was undertaken as part of the EIA, including baseline surveys and stakeholder consultation on the key environmental aspects identified as likely material planning considerations. These key environmental aspects included land quality, archaeology, ecology (bat surveys), noise impacts, air quality, microclimate considerations, drainage and flood risk assessment, townscape and visual context aspects, and waste management. We also took account of potential effects on the local economy and social structure.
Working closely with the architect, client and planning advisers, we identified measures that would reduce and/or eradicate the potential impacts of the proposals on the environment. The resulting environmental statement was submitted as part of a hybrid planning application. We continue to provide consultancy advice on environmental aspects of this project.
masterplanning & urban development
As engineers and environmental consultants, our work in support of the masterplan development for the centre of Preston has encompassed the coordination of an Environmental Impact Assessment, preliminary microclimate analysis and infrastructure services.
The project covers 14.8 hectares of the city centre in a location known as the Heart of the Tithebarn Regeneration Area (HTRA). Major elements of the project include 32 new-build blocks, the refurbishment of existing structures and the relocation of a bus station.
Key environmental aspects considered during the evolution of the scheme include land quality, archaeology, ecology, noise impacts, air quality, potential local economic and social impacts, visual impact, flood risk assessment and waste management.
Our microclimate analysis examined daylight and sunlight availability, and wind flow around site structures and nearby properties with the aim of developing a comfortable environment year-round. Downdraught and wind channelling effects were evaluated in relation to pedestrian comfort. We have also analysed solar penetration, overshadowing and ways to maximise natural light availability.
We undertook 3D earthworks modelling of the proposed bus station area in order to optimise cut and fill design, and we have prepared a comprehensive drainage strategy that minimises sewer diversions and promotes the use of existing sewers. The surface water drainage strategy promotes the use of Sustainable Drainage Systems (SUDS) and includes rainwater harvesting, porous paving and extensive use of 'green/brown' roofs.
