No person shall develop land without obtaining a final project approval in accordance with §
164-1.3A(3) to control or manage runoff from such development except as provided within § 164-3.0. Stormwater management measures shall be designed consistent with the Design Manual and constructed according to an approved plan.
The following development activities are exempt from the provisions
of this chapter:
A. Agricultural land management practices;
B. Additions or modifications to existing single-family detached residential structures if they comply with §
164-3.2C of this chapter;
C. Any developments that do not disturb over 5,000 square feet of land
area; and
D. Land development activities that the Administration determines will
be regulated under specific state laws, which provide for managing
stormwater runoff.
The County Engineer may grant, in writing, a variance from any
requirement of § 164-4.0, Stormwater Management Criteria,
if there are unique physical characteristics of the site such that
strict adherence to the requirements of this chapter will cause unnecessary
hardship. The applicant shall submit a written request for a variance
to the County Engineer, which shall fully describe the specific variance
sought, and reasons for the request. The County Engineer shall not
grant a variance without satisfactory evidence that implementation
of ESD to the MEP has been investigated thoroughly and the above requirements
for a variance have been met.
