Thank you for the quick response, Greg. The O&M need to be completely executed (signed and notarized) and resubmit
before we can approve the system.

We received a hard copy of the Stormwater Management Plan (SMP) for the subject project in our central office. Can
you also provide electronic copy of the submitted package? Either via email (link to shared files) or upload it through our

Bioretention Maintenance Requirements
Important operation and maintenance procedures:
- Immediately after the bioretention cell is established, the plants will be watered twice weekly if needed until the plants
become established (commonly six weeks).
- Snow, mulch or any other material will NEVER be piled on the surface of the bioretention cell.
- Wheeled or tracked equipment will NEVER be driven over the bioretention planting surface.
- Special care will be taken to prevent sediment from entering the bioretention cell.
- If standing water is present 2 days after rainfall, conduct an infiltration test of the soil media.
After the bioretention cell is established, inspect it quarterly. Inspection activities shall be performed as follows and maintenance
activites shall commence immediately to remediate any problems observed per the table below.
