A82 Crianlarich Bypass

WATER FEATURES SURVEY

A bypass is proposed on the A82/A85 junction at Crianlarich

As part of the Scottish Environmental Protection Agency’s (SEPA) requirements for a flood risk assessment, Grontmij undertook a water features survey within the immediate vicinity of the proposed bypass route between the 21st and 23rd April 2008. The survey area covered an area south of the River Fillan, extending southwards towards Creag a’ Bheannain, west to the Old Military Road and east to the edge Crianlarich. The full extent of the survey area is shown on the map at the end of this report.

The following report includes details of all surface water and groundwater features identified within the survey area. The locations of the water features are shown on the map at the end of the report.

No public or private groundwater or surface water abstractions were identified during this survey.
