The temporary silt fence and filter sock will be placed so as not to hinder construction operations. The
contractor will maintain this measure by removing collected sediment and replacing any damaged
segments. If sediment loading is causing the perimeter protection to fail, the deposited sediment will be
removed. Temporary silt fence will remain in place until the construction activities in the area are
complete, and the site has been permanently stabilized. Temporary silt fence and filter sock will be
installed and maintained in accordance with Section 205 of the 2022 Standard Specifications and the
INDOT standard drawings (Attachment E).
To prevent erosion from occurring, temporary seed and temporary mulch will be used in sheet flow areas
during construction. This will also be used in all locations where trees and shrubs are cleared within the
construction limits. Sodding will be applied Disturbed areas that are inactive for more than seven days
will be stabilized with these materials. Areas outside of the construction limits, but within City of Carmel
right-of-way, will be left undisturbed to prevent erosion and act as a filter strip.
7. Run-off Control Measures
Pipe inlet protection will be used at all open ended pipes to control erosion from concentrated flow. See
Erosion Control Details in the construction plan set (Appendix A) and INDOT Specifications and Standard
Drawings (Appendix E).
8. Storm Sewer Inlet Protection Measure Locations and Specifications
Storm sewers do not exist within the project limits. As a result, storm sewer inlet protection does not
apply.
8. Storm Water Outlet Protection Specifications
Storm Water Outlet Protection Specifications will not be necessary for this project.
9. Dewatering applications and management methods
A Temporary pump around and sheet pile cofferdam will be required during the construction of the
bridge pier (Attachment A). The pump around is expected to be in place for approximately 4 weeks.
10. Measures utilized for work within waterbodies
Temporary impacts including the use of cofferdams for temporary dewatering will occur, and are expected
to involve approximately 40.0 linear feet of total impact (0.06 acre, 11.85 cyds) below OHWM as a result
of sheet-pile cofferdams.
11. Maintenance guidelines for each proposed stormwater quality measure.
During construction, storm water quality measures will be maintained in working order. The contractor
will implement a self-monitoring program. All erosion and sediment control measures will be inspected
