CONSTRUCTION OF A NEW DETACHED DWELLING HOUSE, CONSTRUCTION OF A DOMESTIC GARAGE, PROPOSED EFFLUENT TREATMENT SYSTEM AND PERCOLATION AREA AND ALL ASSOCIATED SITE WORKS

Core Refusal Reason

The applicant failed to adequately demonstrate that the site is suitable to accommodate the development due to significant pluvial flood risk and the lack of a sufficient drainage strategy to protect the proposed dwelling.

  • Permitting the development would be contrary to Objective FS-01 of the County Development Plan, which restricts inappropriate development in areas at risk of flooding and is prejudicial to public health and safety.
