13. GROUND CONDITIONS AND
HYDROLOGY
INTRODUCTION
13.1 This section summarises the results of a desk study and walkover survey
of the study area, including the application site and immediate
surroundings. The study area covered in this assessment is
approximately 170 hectares. This section also details the results of a
Flood Risk Assessment (FRA) undertaken by S M Foster Associates Ltd
for the proposed development. The FRA was undertaken in response to a
request from the Environment Agency as part of the EIA Scoping Opinion.
The full FRA report is included in Appendix 9.
13.2 The purpose of the assessment was to identify topographical, geological
and hydrological constraints to the development of wind turbines within the
study area. The main output of the study identified areas where turbine
locations could be constrained due to geological faults, areas of potential
collapse/subsidence and flooding. Such areas were mapped with other
potential constraints at the site to ensure that no turbines or other site
infrastructure were located within them.
13.3 Drawing HJB/681/PA17 (Sheets 1 and 2) shows the ground conditions and
related constraints within the study area and features relating to geology
and hydrology.
METHODOLOGY
13.4 The primary sources of information reviewed as part of the ground
conditions study have included:
Information from Ordnance Survey (OS) plans;
Geological information including British Geological Survey Sheets
295NE, 295SE, 296NW and 296SW at 1:10560 scale; and
A British Geological Survey (BGS) detailed geological assessment
report (dated July 2008). This report is included in Appendix 9.
13.5 The FRA was prepared in accordance with the requirements of “Planning
Policy Statement 25 - Development and Flood Risk”. As the site is situated
in Flood Zone 1 the FRA is primarily focused on assessment of surface
water management requirements and measures required to ensure that
the proposed development does not result in increased flood risk in the
surrounding area.
