06 Surface Water Management Strategy – key principles
Strategic water management
- Surface water management should go beyond minimum legislative requirements. - Surface water should be kept separate and managed on the surface. - There should be no increased flood probability and associated risk form the surface water management system. - Environmental benefit and enhancement should be maximised. - In-curtilage space should be retained as permeable surface to minimise runoff. - ‘Green street’ layouts which integrate habitat and sustainable drainage should be promoted. - Amenity and aesthetic qualities of surface water management features should be maximised. - Appropriate adoption and maintenance should be in place.
Managing and improving water quality and quantity, both within and downstream of the wetland park, is a key component of the park strategy. Wetland habitats in the area are of national importance, and the area’s complex hydrology is one of the most significant development issues. A detailed hydrological model has been developed and used to inform a Hydrological study examining flood risk and future drainage requirements, and propose a Surface Water Management Strategy for the area. Surface water management is a key component of the wetland park vision and strategy, and its links to wider water management. The stated objectives of the Metropolitan Glasgow Strategic Drainage Partnership (MGSDP) are: flood risk reduction; river water quality improvement; enabling economic development; habitat improvement; and integrated investment planning. The wetland park can contribute to delivery on all of these objectives. Current legislation requires new development to attenuate future runoff to undeveloped ‘greenfield’ runoff rates and mitigate future climate change effects to prevent any increased downstream flood risk. Surface water management within the wetland park will go beyond this minimum requirement by taking a more holistic approach which aims to balance environmental constraints and opportunities and link surface water management and Sustainable Urban Drainage Systems (SuDS) to the creation of multi-functional green networks. Surface water drainage, flood attenuation and new SuDS features within the park will be considered not just as surface water management tools but as assets with a broader value to delivering the wetland park vision. Natural drainage will be restored where practicable, and new naturalistic features will be created to link new development to the surrounding landscape, enhance habitat networks and facilitate recreation and access.
