The Dorchester County Department of Public Works shall require
from the developer a surety or cash bond, irrevocable letter of credit,
or other means of security acceptable to the Dorchester County Department
of Public Works prior to the issuance of any building and/or grading
permit for the construction of a development requiring stormwater
management. The amount of the security shall not be less than 120%
of the total estimated construction cost of all stormwater management
facilities. The amount of security shall be based on the construction
cost of all stormwater management facilities, including swales construction,
environmental site design practices, erosion and sedimentation control
measures, road drainage facilities, final site restoration and seeding,
and include an allowance for inspection and preparation and approval
of record drawings. The bond required in this section shall include
provisions relative to forfeiture for failure to complete work specified
in the approved stormwater management plan, compliance with all of
the provisions of this chapter, and other applicable laws and regulations,
and any time limitations. The bond shall not be fully released without
a final inspection of the completed work by the Dorchester County
Department of Public Works, submission of record drawings, and certification
of completion by Dorchester County Department of Public Works that
all stormwater management facilities comply with the approved plan
and the provisions of this chapter. A procedure may be used to release
parts of the bond held by the Dorchester County Department of Public
Works after various stages of construction have been completed and
accepted by the Dorchester County Department of Public Works. The
procedures used for partially releasing performance bonds must be
specified by the Dorchester County Department of Public Works in writing
prior to stormwater management plan approval.
