Surface Water and Flood Risk
The proposed development lies within an identified area of flood plain and has been subjected to a detailed Flood Risk Assessment.
The original planning application relied on an outline flood mitigation strategy that had been produced to support general development in the area and was not specific to the Brigg REP project. Although the Environment Agency had agreed the scheme in principle, the agency felt that it was not appropriate for a planning application to rely on a scheme that only existed in outline form. On the Agency's advice, Eco2 has developed entirely new proposals which deal specifically with the Brigg REP site.
Surface water runoff from the proposed buildings and hardstandings would be managed in such a fashion so as to ensure that the resulting flows are regulated to the equivalent 'green field' runoff rate via the on-site storage ponds into Scawby Beck when conditions in the River Ancholme permit. This, in turn, would ensure that there would be no adverse disturbance to the existing hydrological regime local to the site. If anything, the new scheme represents a major step forward for the area in terms of rainwater management.
The Brigg REP buildings and equipment will sit on the eastern half of the site, which will need to be raised out of the flood plain. An area of compensatory storage would need to be established to contain the waters that would otherwise have settled on the eastern half of the site. This storage will be accomplished by excavating and landscaping the western half of the site. The net result of the land raising and excavation is that the site would be able to safely store 5,700m3 of additional flood waters within its development boundary, over and above the current provision within the flood-plain. The additional storage capacity would help to reduce the wider impacts of future flooding events in the locality, which are known to have caused historical problems in the vicinity of the development site.
Brigg REP would not affect the water quality of the surrounding area.
