Preliminary Ecological Appraisal: Affinity Water

The client: Affinity Water

The site: Takeley Water Tower

The brief: Undertake a Preliminary Ecological Appraisal (PEA) of the habitats on site to assess the potential ecological constraints affecting the development of a booster station and installation of a new water main.

Our solution: The PEA was conducted based on the Guidelines of Preliminary Ecological Appraisal 2016 (Chartered Institute of Ecology and Environmental Management) including assessing the habitats on site and their likely importance for protected species. The habitats on site were considered to be of some ecological value based on their provisions for foraging, sheltering, and dispersal opportunities to bats, small mammals, reptiles, invertebrates and amphibians. The constraints identified above led to a number of requirements and recommendations including; aerial inspection of trees with PRF and precautions to safeguard badgers and reptiles during construction. In addition, great crested newt presence/absence surveys should be undertaken to determine the presence of GCN prior to development. Several opportunities for ecological enhancements on site.

The result: Subject to the completion of further survey work, sensitive deign and the delivery of mitigation and ecological enhancement measures, the proposed development has the potential to deliver net gains for biodiversity, and will comply with ecological legislation as well as national and local planning policies.
