*Reroute or bypass some of the stormwater carrying harmful pollutants while plantings mature (if pollution is deemed the primary cause). Review nearby winter maintenance activities to see if runoff with high concentrations of chloride is reaching the practice. Vegetative maturation may take two growing seasons. | *Reroute or bypass some of the stormwater carrying harmful pollutants while plantings mature (if pollution is deemed the primary cause).

Symptom | Possible Causes | Solution |
---|---|---|
Vegetation will not establish properly | Water levels need to be maintained per species specific growth patterns during establishment. A secondary water source and flow routing may be necessary to establish vegetation for a year. Soils may not have been properly decompacted during construction. Influent pollutant loads may be harming unestablished vegetation. Wildlife may harm unprotected vegetation. |
|
Stagnant water | Significant erosion that has impacted hydraulics. Clogs in the conveyance network. Grading issues. |
|
Mosquitos | Optimal breeding conditions |
|
Wetland capacity is reduced | Sediment build up or vegetative overgrowth |
|
Flow or water imbalance (more water coming in than going out), lower than expected water levels. | Unanticipated infiltration |
