Changes

*'''Cold Climate Considerations''': In colder climates after spring freshet/snow melt, any collected sand/salt from winter time road maintenance must be removed. Further replacement of damaged vegetation should occur as soon as possible after the melt when damage can be adequately surveyed. Added organic matter (generally mulch) may be required especially if drainage to the swale in question is from a corresponding parking lot of roadway. Finally, Deicing agents (salts) can damage soil structure by reducing the soils' organic matter content, inspect and ensure excess loading is not occurring in the feature.
