Dear Ken:
Enclosed for your review are two copies of the Erosion Control Plan
for final stabilization of the referenced addition.
Final stabilization measures consist of cultipack seeding of disturbed
areas in the subdivision, silt barrier fence to control erosion in the
drainage ditch on the West side of the development, and an allowance
to clean-out the storm sewer system discharging along the North
property line.
I have applied a percentage ranging from 50% to 100% of the
anticipated construction costs to be incorporated into the final bond
amount for erosion control. Please note that the unit prices are
estimates and subject to revision once contracts are drawn and erosion
control work completed. Our estimate anticipates a bond amount of
$2,450.00 for this development.
I have instructed my client that a Notice of Termination (N.O.T.)
should be filed with the Environmental Protection Agency once final
stabilization has been established. Any erosion control measures
required after the N.O.T. has been filed shall be the responsibility
of the home builder.
My client also inquired into the time period of the bond. He feels
that this subdivision could be completely built-out before the two-
year bond has expired. Does the City have provisions in the bonding
requirements that allow an early release of funds if the lots are
substantially (or completely) built-out?
Please review the enclosure and contact me with any questions or
comments. Your prompt response in this matter would be greatly
appreciated.
Sincerely,
Cr~Smiley, .
