North East Yorkshire Strategic Flood Risk Assessment, Yorkshire, England
Client: Ryedale District Council
Arup Scope: Strategic Flood Risk Assessment
Arup was appointed by Ryedale District Council, Scarborough Borough Council and North York Moors National Park Authority to undertake a Strategic Flood Risk Assessment (SFRA) for North East Yorkshire.
The aims of the SFRA are to:
- Produce flood risk assessment maps to allow the identification of PPG25 flood risk zones and the
actual level of flood risk within the study area; - Develop guidance to promote consistent decision-making with regard to flood risk for areas
identified for future development.
The SFRA maps flood risk from fluvial flooding, coastal flooding, overland flow, groundwater, and sewer flooding. These flood risk maps were derived from existing flood plain maps, a review of previous studies and flood alleviation scheme design reports and consultation with relevant
authorities.
Arup developed guidance on the application of the sequential test for forward planning purposes to assist planners within Northeast Yorkshire to take flood risk issues into account when producing land allocations in their Local Development Frameworks.
Guidance was also developed on the requirements for Flood Risk Assessments and possible mitigation measures for potential development sites. In addition, guidance was also developed for different flood risk zones, to ensure appropriate development would occur in the future.
The SFRA also investigated the potential for land use management techniques which may be implemented to manage flood risk within the study area, and provides guidance on surface water management and the implementation of Sustainable Drainage Systems. A range of potential land use management measures were identified, for application in upland moorland areas and lowland agricultural areas.
