Draft PPS18: Renewable Energy
Annex 1 Small Hydro Planning Issues: Design Considerations
E22. Although the hydro developments anticipated will generally be small in scale, their waterside location will, in many cases, place them in areas valued for their visual and natural amenity. Such schemes can operate for many decades, and their principal built elements will often become a permanent feature in the landscape. In some circumstances, weirs, fish ladders and turbine houses can become features of interest in their own right.
E23. For these reasons, the Department will expect a high standard of design. Particular attention may need to be given to the architectural quality of built elements, the choice of building materials, and manner in which the development is integrated with its surroundings. Schemes that are in harmony with the surroundings, perhaps incorporating vernacular building materials and styles are to be encouraged.
