Since the promulgation of natural resource damage assessment (NRDA) regulations in 1986, substantial experience has been gained from the NRDAs conducted throughout the United States.These NRDAs encompass a variety of hazardous substances, affected natural resources, and resource services. The NRDAs have ranged from full-scale assessment and litigation among the various parties to cooperative undertakings. W.H. Desvousges & Associates, Inc. has been actively involved in damage assessments since their inception. We are able to offer our clients a full range of strategic and economic services to help them address their NRDA concerns.


Strategic Planning and Evaluation

Because of our extensive knowledge of the damage assessment regulations and the practical experience gained in working on many damage assessments during the past 20 years, W.H.Desvousges & Associates, Inc. can assist our clients in determining the best strategic approach for a particular damage assessment. Our experience ranges from expedited settlements of modest cases to complicated litigation involving multiple resource services. We are able to advise our clients as to the advantages and disadvantages of each approach. We also have worked in various settings, including some of the more effective cooperative assessments. We also have extensive knowledge of the approaches that natural resource trustees commonly use in damage assessments, and the critical issues that can arise with each approach. We also have been able to independently evaluate assessments that are being conducted by others to determine whether the current strategic approach is working or whether another alternative might be more fruitful.


Assessment Design and Planning

W.H. Desvousges & Associates, Inc. has written several assessment plans and has written comments on trustees’ assessment plans for many major damage assessments.  We also have conducted numerous assessments for a diverse range of resources and locations. This experience enables us to assist our clients with a range of needs that might arise as part of planning an NRDA. We have had considerable experience in working as part of an assessment team to develop the necessary linkages between the natural science studies and the economic studies to ensure that the assessment is fully integrated. 


Participating in Cooperative Assessments

W.H. Desvousges & Associates, Inc. has participated in several cooperative assessments, including the Lavaca Bay assessment, which has been used by many as the model for cooperative assessments. We can assist our clients by participating in technical working group meetings to resolve key human use issues or help evaluate restoration alternatives. Because of our technical knowledge and experience, we are able to effectively represent our clients in either informal meetings or in formal negotiation sessions that may end up being part of a cooperative assessment.


Participating in Expedited Assessments

Sometimes clients find themselves in a situation where they want to settle an NRDA case quickly and as cost-effectively as possible. W.H. Desvousges & Associates, Inc. has assisted many clients by conducting expedited assessments that enable settlement offers to be developed and implemented. These expedited assessments use available data and models to develop ranges of potential losses for various service losses. They also evaluate potential restoration projects that can serve as part, if not all, of the settlement offer. We also have assisted clients by helping to present the settlement offer to natural resource trustees so that the underlying factual data and models can be clearly explained.
