Maintenance Agreements:
Section 4 VAC 50-60-124 of the regulations specifies the circumstances under which a
maintenance agreement must be executed between the owner and the local program. This section
sets forth inspection requirements, compliance procedures if maintenance is neglected, notification
of the local program upon transfer of ownership, and right -of -entry for local program personnel.
All Vegetated Filter Strips must be covered by a drainage easement to allow inspection and
maintenance. If the filter area is a natural Conserved Open Space, it must be protected by a
perpetual easement or deed restriction that assigns the responsible party to ensure that no future
development, disturbance or clearing may occur within the area, except as stipulated in the
vegetation maintenance plan.
If the Vegetated Filter Strip is located on a residential private lot, the existence and purpose of the
Filter Strip shall be noted on the deed of record. Homeowners will need to be provided a simple
document that explains the purpose of the Filter Strip and routine maintenance needs. A deed
restriction or other mechanism enforceable by the qualifying local program must be in place to
help ensure that Filter Strips are maintained and Conserved Open Space Areas are not converted
or disturbed. The mechanism should, if possible, grant authority for local agencies to access the
property for inspection or corrective action.
Maintenance inspections:
Annual inspections are used to trigger maintenance operations such as sediment removal, spot
revegetation and level spreader repair. Ideally, inspections should be conducted in the non -growing
season when it easier to see the flow path. Example maintenance inspection checklists for Sheet
Flow to a Filter Strip or Conserved Open Space areas can be accessed in Appendix C of Chapter
9 of the Virginia Stormwater Management Handbook or at the Center for Watershed Protection's
website at:
http://www.cwp.org/Resource_Library/Controlling_Runoff_and_Discharges/sm.htm (scroll to
Tool6: Plan Review, BMP Construction, and Maintenance Checklists)
Inspectors should check to ensure that:
• Flows through the Filter Strip do not short-circuit the overflow control section;
• Debris and sediment does not build up at the top of the Filter Strip;
• Foot or vehicular traffic does not compromise the gravel diaphragm;
• Scour and erosion do not occur within the Filter Strip;
• Sediments are cleaned out of Level Spreader forebays and flow splitters; and
• Vegetative density exceeds a 90% cover in the boundary zone or grass filter.
On¢oin¢ Maintenance
Once established, Vegetated Filter Strips have minimal maintenance needs outside of the spring
clean up, regular mowing, repair of check dams and other measures to maintain the hydraulic
efficiency of the strip and a dense, healthy grass cover. Vegetated Filter Strips that consist of
grass/turf cover should be mowed at least twice a year to prevent woody growth.
