Bioretention Inspection and Maintenance Agreement
'D1"h TqW -r-oN .42v.+ #5l THSA1gr4D4&/f
I will keep a maintenance record on this BMP. This maintenance record will be kept in a
log in a known set location. Any deficient BMP elements noted in the inspection will be
corrected, repaired or replaced immediately. These deficiencies can affect the integrity
of structures, safety of the public, and the removal efficiency of the BNT.
Important inspection 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.
Heavy equipment will NEVER be driven over the bioretention cell.
— Special care will be taken to prevent sediment from entering the bioretention cell.
— Once a year, a soil test of the soil media will be conducted.
After the bioretention cell is established, I will inspect it once a month and within 24
hours after every storm event greater than 1.0 inches (or 1.5 inches if in a Coastal
County). Records of inspection and maintenance will be kept in a known set location
and will be available upon request.
Inspection activities shall be performed as follows. Any problems that are found shall
be repaired immediately.

it is necessary.
Remove tree stake /wires (which
can kill the tree if not removed).

Determine the extent of the clogging
- remove and replace either just the
top layers or the entire media as
needed. Dispose of the spoil in an
appropriate off -site location. Use
triple shredded hard wood mulch at
a maximum depth of three inches.
Search for the source of the

Dolomitic lime shall be applied as
recommended per the soil test and
toxic soils shall be removed,
disposed of properly and replaced
with new planting media.

RE: Bioretention Soil 3729 Overlook Road
Raleiah..NQ. 27616
ftvMdOW17/2010 Attu: Robert Bradsher
Recommendations:
A complete physical analysis and panicle sloe analysis, including organic matter and pH, were made
on the Biosoil Sample from R. L. Bradsher Contracting, Inc. on January 11, 2012, to determine its
physical properties for a Bioretention Soil. The condition of the sample as received was normal,
The particle size analysis shows that the Biosoil is composed of a light tan colored, coarse medium sand
with 88.0% sand, 7.0% silt, and 5.0% clay, including the 0.5% fine gravel in the sand fraction. The
Biosoil has 12.0% silt and clay, which meets the recommendation of 8 -12% silt and clay for this
Biosoil.
The Biosoil has 3.76% organic matter by weight as determined by the loss on ignition method (ASTM
F1547), which meets the recommendation of 3 -5% organic matter for this Biosoil.
The Biosoil has a water permeability rate of 2.9 in /hr. when compacted by the ASTM F1815 method
to simulate a compacted agricultural topsoil (2.9 ft..lbsAn2), which is within the recommendation of 1 -6
, /hr. for this Biosoil.
The other physical properties show that this soil has 14,7% non - capillary (air - filled) porosity, 29.3%
capillary (water - filled) porosity, and an adequate water retention of 20,2 %.
The Biosoil has a soil water pH of 5.6, which is a little lower than the optimum pH range of 6.0 to 6.5
for most plant growth.
Conclusion: This Biosoil meets the Bioretention Soil Specifications that you are trying to meet.
Recommendations are'based on the samples received. Results and comments relate to the samples tested. This
report cannot be reproduced except in full, and not without written approval of the laboratory.

The planting soil should be a homogenous soil mix., by weight,
consist' of
85 -88% SAND

Planting soil media should be at minimum a depth of 2 ft,
After planting soil has been placed permeability should be tested and
should fall between 0.52 - 6 in/hr, 1-2 in/hr is preferred,
