“…Major maintenance items would pertain to critical deficiencies that require partial or complete rebuilds of the facility (Kang et al 2008;Erickson et al 2009;Flynn et al 2012). These levels of maintenance are helpful in establishing maintenance schedules and items.…”

“…Careful consideration of GSI must be taken while determining construction E&SC plans and construction sequencing (Flynn et al 2012). One of the primary concerns of construction affecting GSI is the premature introduction of sediment laden runoff clogging filter media and/or underlying soils (Hunt and Lord 2004;Livingston et al 1997).…”

“…Maintenance of GSI is performed to ensure functionality over their life cycle as well as preserve aesthetic qualities (Flynn et al 2012). Maintenance can typically be broken into different levels depending on the type, frequency, and intensity required.…”

Construction and maintenance can have huge implications on the long-term functioning of GSI facilities. GSI facilities investigated were bioretention, permeable pavement, sand filters, infiltration trenches, and vegetated swales. This study first highlights the most important construction and maintenance items based on relevant studies and state stormwater manuals. Fairfax County, VA was used as a case study to evaluate the County's current stormwater program and illuminate common maintenance issues found for each GSI type. Data analysis of 3141 inspection records illustrated particular deficiencies for each GSI type and that there are differences between public and private facilities, most likely depending on site conditions and frequency of routine maintenance. Sediment accumulation was found to be the most common maintenance issue (27.8% of inspections), supporting the importance of adequate pretreatment and good housekeeping when implementing GSI. The Northern Virginia Soil and Water Conservation District (NVSWCD) performed a study surveying 63 public bioretention facilities in which they measured ponding depth, filter media depth, ponding area, and infiltration rates. The NVSWCD concluded that deficiencies found in facilities could mostly be attributed to inadequacies during construction. By comparing current post-construction inspections performed by the County to the NVSWCD data, it was found that these County inspections are failing to detect these inadequacies in bioretention facilities from improper construction. It is recommended that MS4s thoroughly record and track construction and post-construction inspection items to improve the longevity of its facilities and better inform future decision making regarding GSI.

“…Barret (2003) also verified that the routine requiring more labor demand was the inspection, since it has to be done weekly. Moreover, Flynn et al (2012) raised as main maintenance for bioretention the care with vegetation, especially the irrigation.…”
