Strategic Environmental Assessment
Cascade Consulting has leading edge expertise in Strategic Environmental Assessment (SEA), particularly within the water sector. The company’s depth of experience in strategic planning and long term option appraisal is applied in undertaking SEA for both public and private sector clients.
SEA requires a wide knowledge of the planning system, in terms of both the nature and potential interaction of extant plans and programmes and how these interactions can result in potential cumulative impacts on the environment. Cascade’s core team combine planning expertise with extensive experience in environmental assessment, which allows a clear and pragmatic identification of key strategic issues. Cascade goes one step further, using its past experience in managing interfaces between different developers, to ascribe impacts to each of the proponent plans and to develop an integrated and rational programme for mitigating these impacts to acceptable levels.
The company’s skills in stakeholder management are crucial in this respect because the team recognises that an SEA is only valuable if the proponents of the plans and programmes involved can be successfully persuaded to “buy in” and fully commit to the process of assessment and integrated mitigation.

Our services include:

We have particular experience in developing assessment methodologies for comparing and evaluating alternatives, based on trade-offs between the cost, risk and the environmental and social impacts of different options. The company has developed a methodology which allows a wide range of plan or programme performance indicators to be quantified, which aids in the identification and selection of preferred alternative. This can be useful in presenting complex information on a wide range of potential alternatives in a more easily understood form to both consultees and the wider public.
The company also provides expert witnesses for Public Inquiries where SEA has been used to support the selection of options which are subsequently taken forward for development.
