Water Quality prepared statements

Use the following statement on all projects that impact surface waters except for those that are bridge replacements over water:

This project will not increase the existing impervious surface area and associated highway runoff and it will not change the existing drainage system, therefore, no significant impacts on water quality should result.

Use the following statement for bridge replacement projects over water,  

This project will be designed so that bridge runoff is directed to the ends of the bridge if feasible; thereafter, drainage water will flow over vegetated areas or to treatment areas before reaching surface waters, therefore bridge runoff will not significantly impact water quality.
