The synergies were identified at an early stage and the environmental surveys to inform the baseline were designed to inform the EIA for both Project One and Project Two. iv sdf 1. ENVIRONMENT AGENCY ENVIRONMENTAL INFORMATION Node Map Please find attached maps showing a selection of model node points near to your site. The fluvial levels, flows and bank levels for these node points are shown in the attached datasheet. This information is from the Louth Canal Model (2009) and the River Freshney and New Cut Drain Model (2009). Tidal Flood Levels Please find attached available tidal flood levels as requested. These levels have an assessment date of 2006, which should be used in any consideration of future Jonathan Morley Our ref: CCN/2013/34220 increases due to climate change.

Flood Map for Surface Water The Flood Map for Surface Water provides a general indication of areas that may be at risk of surface water flooding. It takes broad account of underground drainage and typical storms which are likely to cause flooding, but these are only typical national figures and are not appropriate everywhere. The maps indicates two depths of flooding: greater than 0.1m deep, and greater than 0.3m deep. This information is provided subject to the enclosed notice, which you should read.
