Exhibit C
Minimum Storm Water Practice Maintenance Requirements
This exhibit explains the basic function of each of the storm water practices listed in Exhibit B and
prescribes the minimum maintenance requirements to remain compliant with this Plan. The maintenance
activities listed below are aimed to ensure these practices continue serving their intended functions in
perpetuity. The list of activities is not all-inclusive, but rather indicates the minimum type of maintenance
that can be expected for this particular site.
BIOFILTER
.system Desyrription:
The biofilter is designed to remove at least 40% of the Total Suspended Solids (TSS) in its drainage area
runoff and to reduce downstream peak flows. Grass swales function to convey runoff to the biofilter, as
well as filter pollutants, especially from smaller storms. To function correctly, the biofilter size and outlet
structures must be maintained as specified in this Plan (see Exhibits B and Q.
Minimum Maintenance Requirements:
The project includes new storm sewer pipes, new catch basins, and a biofilter (biofiltration). The catch basins
will have a 24" minimum sumps. These items require regular inspections and maintenance as required. We
have listed below each of these items and the required inspection and potential maintenance required. The
plans developed for this project fully describe the locations of these items.
New storm sewer pipes and culverts should be inspected to ensure the inlet and outlets are not clogged with
debris. These pipes should be inspected a minimum of two times a year. Maintenance includes removing
any accumulated debris and/or sediment.
Concrete catch basins require regular inspection and maintenance as well. The catch basins should be
inspected a minimum of two times a year. Maintenance includes removing any accumulated debris and/or
sediment. Sediment should be removed when the level has reached 50% of the capacity of the sump.
The biofilter contains two overflow catch basins (described above). The draintile line at the bottom of the
biofilter discharges to the catch basin. A new storm sewer pipe connects to the biofilter catch basins and
discharges under the drive to an area of rip rap along the north property line. The catch basins should be
inspected as outlined above. Required biofilter maintenance activities are listed below:
Actives Frequency
1. Water Plants As necessary during first growing season
2. Water as necessary As needed after first growing season
during dry periods
3. Re -mulch void areas
4. Treat diseased plants
5. Inspect soil and repair
eroded areas
6. Remove liter and debris
7. Add additional mulch
8. Inspect for sediment
buildup and clogging
As needed
As needed
Monthly
Monthly
Once per year
Inspect once per year. The system must be checked
annually, and after significant rainfall (>1.5") to determine
if the infiltration rate is slow or if the system is clogged. If the
draw down time exceeds 24 hours, a visible sediment layer is
present, or if it is visibly apparent that runoff is running directly
Page 7 of 8
through the overflow structure, the system is clogged, and one
or more of the following corrective actions must be completed.
If areas of the system become clogged, then the removal of
engineered soil, stone and sediment should be perfonned for the
area in question. The same fill and cross section of the system
should be maintained. Replacement of plant material consistent
with the planting schedule should be used.
9. Inspect plants Once per year —replace dead plants (if any)
In addition, snow shall not be dumped/plowed directly onto the conditioned planting bed of the biofilter.
