This chapter shall be known and may be cited as the "Erosion
and Sediment Control Chapter of Dorchester County."
As used in this chapter, the following terms shall have the
meanings indicated:
ADVERSE IMPACT
Any deleterious effect on waters or wetlands, including their
quality, quantity, surface area, species composition, aesthetics or
usefulness for human or natural uses. Such deleterious effect is or
may potentially be harmful or injurious to human health, welfare,
safety or property or to biological productivity, diversity or stability
or unreasonably interfere with the enjoyment of life or property,
including outdoor recreation.
AGRICULTURAL LAND MANAGEMENT PRACTICES
Those methods and procedures used in the cultivation of land
in order to further crop and livestock production and the conservation
of related soil and water resources. Logging and timber-removal operations
may not be considered a part of this definition.
APPLICANT
Any person, firm, or government agency that executes the
necessary forms to procure official approval of the project or a permit
to carry out the construction of a project.
APPROVAL AUTHORITY
The entity responsible for the review and approval of erosion
and sediment control plans. The Dorchester Soil Conservation District
shall be responsible for the review and approval of erosion and sediment
control plans.
BEST MANAGEMENT PRACTICE (BMP)
A structural device or nonstructural practice designed to
temporarily store or treat stormwater runoff in order to mitigate
flooding, reduce pollution, and provide other amenities.
CLEAR
Any activity which removes the vegetative ground cover while
leaving the root mat intact.
DEPARTMENT
The Maryland Department of the Environment.
DRAINAGE AREA
That area contributing runoff to a single point, measured
in a horizontal plane, which is enclosed by a ridge line.
ENVIRONMENTAL SITE DESIGN (ESD)
The use of small-scale stormwater management practices, nonstructural
techniques, and better site planning to mimic natural hydrologic runoff
characteristics and minimize the impact of land development on water
resources.
EROSION
The process by which the land surface is worn away by the
action of wind, water, ice or gravity.
EXEMPTION
Those land development activities that are not subject to
the erosion and sediment control requirements contained in this chapter.
FINAL EROSION AND SEDIMENT CONTROL PLAN
Along with the final stormwater management plan, the last
of three plans submitted under the comprehensive review and approval
process required by the Act and described in COMAR 26.17.02. Final
erosion and sediment control plans shall be prepared and approved
in accordance with the specific requirements of the Dorchester Soil
Conservation District and this chapter and designed in accordance
with the Standards and Specifications.
GRADE
To cause the disturbance of earth. This shall include but
not be limited to any excavating, filling, stockpiling of earth materials,
grubbing, root mat or topsoil disturbance, or any combination of them.
GRADING UNIT
The maximum contiguous area allowed to be graded at a given
time. For the purposes of this chapter, a grading unit is 20 acres
or less.
HIGHLY ERODIBLE SOILS
Those soils with a slope greater than 15% or those soils
with a soil erodability factor, K, greater than 0.35 and with slopes
greater than 5%.
INSPECTION AGENCY
The Department or, if enforcement authority is delegated,
the Dorchester County Department of Public Works.
MAXIMUM EXTENT PRACTICABLE (MEP)
The designing of stormwater management systems so that all
reasonable opportunities for using ESD planning techniques and treatment
practices are exhausted and only where absolutely necessary is a structural
BMP implemented.
OWNER/DEVELOPER
A person undertaking, or for whose benefit, activities covered
by this chapter are carried on. General contractors or subcontractors,
or both, without a proprietary interest in a project are not included
within this definition.
PERMITTEE
Any person to whom a grading permit has been issued.
PERSON
Includes the federal government, the state, any county, municipal
corporation or other political subdivision of the state or any of
their units or an individual, receiver, trustee, guardian, executor,
administrator, fiduciary or representative of any kind or any partnership,
firm, association, public or private corporation or any of their affiliates
or any other entity.
PRELIMINARY LAND DEVELOPMENT PLAN
The second of three plans submitted under the comprehensive
review and approval process required by the Act and described in COMAR
26.17.02. A preliminary land development plan shall include the information
necessary to allow a detailed evaluation of a proposed project.
RESPONSIBLE PERSONNEL
Any foreman, superintendent or project engineer who is in
charge of on-site clearing and grading operations or the implementation
and maintenance of an erosion and Sediment control plan.
SEDIMENT
Soils or other surficial materials transported or deposited
by the action of wind, water, ice, gravity or other artificial means.
SITE
Any tract, lot or parcel of land or combination of tracts,
lots or parcels of land which are in one ownership or are contiguous
and in diverse ownership, where development is to be performed as
part of a unit, subdivision or project.
SKETCH PLAN
The first of three plans submitted under the comprehensive
review and approval process required by the Act and described in COMAR
26.17.02 and shall include the information necessary to allow an initial
evaluation of a proposed project.
STABILIZATION
The prevention of soil movement by any of various vegetative
and/or structural means.
STANDARDS AND SPECIFICATIONS
The "2011 Maryland Standards and Specifications for Soil
Erosion and Sediment Control" or any subsequent revisions.
STORMWATER
Water that originates from a precipitation event.
STORMWATER MANAGEMENT SYSTEM
The natural areas, ESD practices, stormwater management measures,
and any other structure through which stormwater flows, infiltrates,
or discharges from a site.
VARIANCE
A modification of the minimum erosion and sediment control
requirements for exceptional circumstances such that strict adherence
to the requirements would result in unnecessary hardship and not fulfill
the intent of this chapter.
WATERSHED
The total drainage area contributing runoff to a single point.
WETLANDS
Any area that has saturated soils or periodic high groundwater
levels and vegetation adapted to wet conditions and periodic flooding.
No approval, permit, variance or special exception for any property
located within the Critical Area as regulated by this chapter shall
be issued, unless the person seeking the permit, approval, variance
or special exception has:
A. Fully paid all administrative, civil, and criminal penalties imposed
by this chapter for violation for the subject property within the
Critical Area; and
B. Prepared a restoration or mitigation plan approved by the County
to abate impacts to water quality or natural resources as a result
of the violation for the subject property within the Critical Area;
and
C. Performed the abatement measures in the approved plan in accordance
with the County's Critical Area Program, for the subject property,
under this chapter; and
D. Satisfaction of all conditions specified under this section shall
be a condition precedent to the issuance of any permit, approval,
variance, or special exception for the affected property; and
E. Unless an extension of time is appropriate because of adverse planting
conditions, within 90 days of the issuance of a permit, approval,
variance, or special exception for the affected property, any additional
mitigation required as a condition of approval for the permit, approval,
variance, or special exception shall be completed.
If any portion, section, subsection, sentence, clause or phrase
of this chapter is, for any reason, held invalid or unconstitutional
