These regulations have been in place for some time, but the Metro Nashville Stormwater Division is turning attention toward a proactive approach to enforcement of compliance measures. There are a few simple steps business managers and facility managers can take to make sure compliance is continued and prepare for their annual inspection.
What you need to know about bio-retention space and why it’s important to your facility For facility managers: (from “Nashville.gov - Stormwater - Green Infrastructure Practices - Bio-retention.”)
Routine and Non‐Routine Maintenance Tasks Maintenance of bio-retention areas should be integrated into routine landscape maintenance tasks. If landscaping contractors will be expected to perform maintenance, their contracts should contain specifics on unique bio-retention landscaping needs, such as maintaining elevation differences needed for ponding water, proper mulching, sediment/trash removal, and limited use of fertilizers and pesticides.
A customized maintenance schedule must be prepared for each bio-retention facility. Tasks will differ depending on the scale of bio-retention, the landscaping template chosen, and the type of surface cover.
The most common non-routine maintenance problem involves standing water. If water remains on the surface for more than 48 hours after a storm, adjustments to the grading may be needed or under-drain repairs may be needed.
Suggested Annual Maintenance Activities for Bio-retention
Mowing of grass filter strips and bio-retention turf cover at least 4 times a year
Remove invasive plants using recommended control methods as needed
Stabilize the contributing drainage area to prevent erosion as needed
Spring inspection and cleanup annually
Supplement mulch to maintain a 3-inch layer annually
Prune trees and shrubs annually remove sediment in pre‐treatment cells and inflow points once every 2 to 3 years
Spot weeding, erosion repair, trash removal, and mulch raking twice during the growing season
Add reinforcement planting to maintain desired vegetation density as needed
Replace the mulch layer every 3 years
