1. Implement sediment control practices in order to minimize sediment from entering surface waters, including
curb and gutter systems and storm drain inlets.
2. Install all temporary or permanent sediment control measures including silt fence at perimeter of
construction, bio -logs at driveway, sediment filters, silt sacks, and sedimentation basins pdQr to beginning
site clearing, grading, or other land -disturbing activity. Protect all storm sewer inlets that receive runoff
from disturbed areas.
3. Establish sediment control practices on all down gradient perimeters before any up gradient land disturbing
activities begin. These practices must remain in place until final stabilization has been established.
4. The timing of the installation of sediment control practices may be adjusted in order to accommodate
short-term activities, but sediment control practices must be installed before the next precipitation event
even if the short-term activity is not complete.
5. If the down gradient treatment system becomes overloaded, install additional up gradient sediment control
practices or redundant BMPs in order to eliminate the overloading.
6. Before beginning construction, install a TEMPORARY ROCK CONSTRUCTION ENTRANCE at each point where
vehicles exit the construction site. Use 25 mm (1 inch) to 50 mm (2 inch) diameter rock, MNDOT
Standard Specification 3137 CA -1, CA -2, CA -3, or equal Coarse Aggregate. Place the aggregate in a layer
at least 152 mm (6 inches) thick across the entire width of the entrance. Extend the rock entrance at
least 15 m (50 feet) into the construction zone. Use a MNDOT Standard Specification 3733 Type V
permeable geotextile fabric material beneath the aggregate in order to prevent migration of soil into the
rock from below. Maintain the entrance in a condition that will prevent tracking or flowing of sediment onto
paved roadways. Provide periodic top dressing with additional stone as required. Close entrances not
protected by temporary rock construction entrances to all construction traffic.
7. If necessary, clean the wheels of construction vehicles in order to remove soils before the vehicles leave the
construction site. Wash vehicles only on an area stabilized with stone that drains into an approved
sediment trapping device.
8. Remove all soils and sediments tracked or otherwise deposited onto adjacent property, pavement areas,
sidewalks, streets, and alleys. Removal shall be on a daily basis throughout the duration of the
construction. Clean paved roadways by shoveling, wet -sweeping, or dry sweeping. If necessary, scrape paved
surfaces in order to loosen compacted sediment material prior to sweeping. Haul sediment material to a
suitable disposal area. Street washing is allowed only after sediment has been removed by shoveling or
sweeping.
9. Soil Stockpiles: Install siltfence or other effective sediment controls around all temporary soil stockpiles.
Locate soil or dirt stockpiles such that the downslope drainage length is no less than 8 m (25 feet) from
the toe of the pile to a surface water, including stormwater conveyances such as curb and gutter systems,
or conduits and ditches unless there is a bypass in place for the stormwater. If remaining for more than
7 days, stabilize the stockpiles by mulching, vegetative cover, tarps, or other means. During street repair,
cover construction soil or dirt stockpiles located closer than 8 m (25 feet) to a roadway or drainage
channel with tarps, and protect storm sewer inlets with silt sacks or staked siltfence.
10. Silt Fence: Install silt fence along the contour (on a level horizontal plane) with the ends turned up
(J -hooks) in order to help pond water behind the fence. Install the silt fence on the uphill side of the
support posts. Provide a post spacing of 1.2 m (4 feet) or less. Drive posts at least 0.6 m (2 feet)
into the ground. Anchor the silt fence fabric in a trench at least 152 mm (6 inches) deep and 152 mm
(6 inches) wide dug on the upslope side of the support posts. Lay the fabric in the trench and then
backfill and compact with a vibratory plate compactor. Make any splices in the fabric at a fence post. At
splices, overlap the fabric at least 152 mm (6 inches), fold it over, and securely fasten it to the fence
post. Silt fence supporting posts shall be 51 mm (2 inch) square or larger hardwood, pine, or standard
T- or U -section steel posts. T- or U -section steel posts shall weigh not less than 1.8602 kg per meter
(1.25 Ib per lineal foot). Posts shall have a minimum length of 1524 mm (5 feet). Posts shall have
projections to facilitate fastening the fabric and prevent slippage. Geotextile fabric shall meet the
requirements of MNDOT Standard Specification 3886 for preassembled silt fence, furnished in a continuous
roll in order to avoid splices. Geotextile fabric shall be uniform in texture and appearance and have no
defects, flaws, or tears. The fabric shall contain sufficient ultraviolet (UV) ray inhibitor and stabilizers to
provide a minimum two-year service life outdoors. Fabric color shall be international orange.
11. Maintain all temporary erosion and sediment control devices in place until the contributing drainage area has
been stabilized (hard -surfaced areas paved and vegetation established in greenspace). Repair any rilling,
gully formation, or washouts. After final establishment of permanent stabilization, remove all temporary
synthetic, structural, and nonbiodegradable erosion and sediment control devices and any accumulated
sediments. Dispose -of off site. Restore permanent sedimentation basins to their design condition
immediately following stabilization of the site.
12. If dewatering is required and sump pumps are used, all pumped water must be discharged through a
sediment control device such as a dewatering bag or other appropriate facility prior to leaving the
construction site. Proper energy dissipation must be provided at the outlet of the pump system.
I N S P E C T 1 0 N S A N D M A I N T E N A N C E:
1. Inspect the entire construction site at least once every 7 days during active construction and within 2.4 hours
after a rainfall event greater than 0.5 inches in a 24-hour period. Following an inspection that occurs within
24 hours after a rainfall event, the next inspection must be conducted within 7 days after that rainfall event.
2. Inspect all erosion prevention and sediment control BMPs, infiltration areas, and stabilized areas.
3. Record all inspections and maintenance conducted during construction in writing and keep these records. The
inspections and maintenance records must include date and time of inspections, date and amount of all
rainfall events greater than 0.5 inches in a 24-hour period, name of persons(s) conducting inspections,
findings of inspections, recommendations for corrective actions, and any corrective actions taken.
4. Inspect all erosion prevention and sediment control BMPs in order to ensure integrity and effectiveness.
Repair, replace, or supplement any nonfunctional BMPs with functional BMPs within 24 hours after discovery,
or as soon as field conditions allow access unless another time frame is specified.
5. Remove accumulated sediment deposits from behind erosion and sediment control devices as needed. Do not
allow sediment to accumulate to a depth of more than one-third of the height of the erosion and sediment
control devices. Repair, replace, or supplement deteriorated, damaged, rotted, or missing erosion control
devices within 24 hours of discovery, or as soon as field conditions allow access.
6. Repair, replace, or supplement all silt fences when they become nonfunctional or the sediment reaches 1/3
of the height of the fence. These repairs must be made within 24 hours of discovery, or as soon as field
conditions allow access.
7. Clean sedimentation basins, storm sewer catch basins, ditches, and other drainage facilities as required in
order to maintain their effectiveness. Temporary and permanent sedimentation basins must be drained and
the sediment removed when the depth of sediment collected in the basin reaches 1/2 of the storage volume.
Drainage and removal must be completed within 72 hours, or as soon as field conditions allow access.
8. Inspect surface waters (including drainage ditches and conveyance systems) evidence of erosion and sediment
deposition. Remove all deltas and sediment deposited. Stabilize areas where sediment removal results in
exposed soil. Removal and stabilization must be completed within 7 days of discovery unless precluded by
legal, regulatory, or physical access constraints. If precluded, removal and stabilization must take place within
7 days of obtaining access.
9. Inspect construction site vehicle exit locations for evidence of off-site sediment tracking onto paved surfaces.
Remove all soils and sediments tracked or otherwise deposited onto adjacent property, pavement areas,
sidewalks, streets, and alleys. Removal shall be on a daily basis throughout the duration of the construction.
Clean paved roadways by shoveling or wet -sweeping. Do not dry sweep. If necessary, scrape paved surfaces
in order to loosen compacted sediment material prior to sweeping. Haul sediment material to a suitable
disposal area. Street washing is allowed only after sediment has been removed by shoveling or sweeping.
10. Perform any corrective measures ordered by the City or Watershed District within 24 hours of notification.
Install any additional erosion protection or sediment control measures deemed necessary by the City or
Watershed District within 24 hours of notification.
E R 0 S 1 0 N P R E V E N T 1 0 N P R A C T I C E S:
1. Delineate the location of areas not to be disturbed (e.g. with flags, stakes, signs, silt fence, etc.) on the
development site before work begins.
2. Avoid removal of trees and surface vegetation wherever possible. Schedule construction in order to
expose the smallest practical area of soil at any given time. Implement appropriate construction phasing,
vegetative buffer strips, horizontal slope grading, and other construction practices that minimize erosion.
3. Following initial soil disturbance or redisturbance, complete permanent or temporary stabilization against
erosion due to rain, wind, and running water as soon as possible, but in no case later than 14 calendar
days, on all disturbed or graded areas including stormwater management pond sideslopes. This
requirement does not apply to those areas that are currently being used for material storage or for those
areas on which grading, site building, or other construction activities are actively underway.
4. Provide temporary grass seed cover on all topsoil stockpiles and other areas of stockpiled excavated
material in order to prevent soil erosion and rapid runoff during the construction period. Prolonged
periods of open, bare earth without grass cover will not be permitted. Stabilize all disturbed greenspace
areas with a minimum of 4" topsoil immediately after final subgrade completion. Seed and mulch, or sod
and stake these areas within 48 hours after completion of final grading work (weather permitting).
5. Stabilize all disturbed areas to be paved using early application of gravel base.
6. Apply necessary moisture to the construction area in order to prevent the spread of dust.
