The objective of this research is to develop guidelines for reducing the runoff volume from limited-access highway facilities in urban areas to meet proposed EPA regulatory requirements. The guidelines should provide assistance to state DOTs and other transportation agencies to:
- Identify or develop viable solutions that can be applied within the highway right-of-way. These could include typical current methods or new and innovative approaches. The solution must be appropriate for specific site conditions (e.g., soil type, climate, utilities, right-of-way constraints, and local hydrology).
- Evaluate potential solutions by comparing factors such as expected cost, performance, safety, effects on surrounding infrastructure, maintenance requirements, roadway operations, and life span.
- In cases where it is not feasible or practical to achieve adequate runoff volume reduction within the highway right-of-way, the guidelines should identify and evaluate other approaches and solutions outside the highway right-of-way to reduce the volume of runoff. Contingent upon the extent of guidance that can be provided for items (1) and (2) above, item (3) may be assigned a higher or lower priority.
The final report has been published as NCHRP Report 802.
