The objectives of this research are to: (1) Catalog recommended hydrologic methods for water quality found in state and other agency drainage design and stormwater manuals available online; (2) Catalog general stormwater quality requirements for the jurisdictions from which manuals have been acquired and summarize proposed USEPA regulations as they affect highways; (3) Perform a literature search for international application of techniques for water quality hydrology; (4) Categorize and evaluate the identified techniques and methods based on the type of methodology (e.g. design storm versus continuous simulation), technical foundation, applicability, and other considerations; (5) Identify and interview representatives from 5 to 10 organizations that use broadly applicable, appropriate, and effective techniques to gain further insight into the source of these techniques and their experience with them, and (6) Document the findings of this research effort including recommendations for further research, if needed. The product is complete and the final report sent to AASHTO for distribution.
