Summary of Natural England’s advice dated 15th October 2020 As set out within the formal written response issued by Natural England dated 15th October, a summary of Natural England’s advice is as follows: “Some of the assumptions are not precautionary, or differ materially from the values suggested in the Natural England nutrient neutral methodology. Where this is the case, we advise values should be evidenced in the update to the local plan appropriate assessment that is required. As the competent authority Folkestone and Hythe should satisfy itself that the values chosen and assumptions made are consistent with others used in the local plan, and are sufficiently precautionary to meet the tests for assessments of plans and projects set out in the Conservation of Habitats and Species Regulations (2017) as amended (HRA). Natural England’s advice is that the local plan supporting documents have the potential to meet the HRA tests for water quality at the plan level, subject to suggested changes and amendments provided in our detailed advice contained in Annex I to this letter. We draw attention to our advice that additional areas of wetland mitigation may be required above those listed in the Otterpool updated memo. Clarification of the difference in the nutrient budgets in the updated memo appendices, compared with those in the Local Plan for Otterpool options is required. Our role with regards protected species is in Annex II.” Folkestone & Hythe District Council – Update on Discussions with Natural England 4.
