indicated.
ADMINISTRATION
The Maryland Department of the Environment (MDE) Water Management
Administration (WMA).
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 which are, or may potentially
be harmful, or injurious to human health, welfare, safety or property,
to biological productivity, diversity, or stability or which unreasonably
interfere with the enjoyment of life or property, including outdoor
recreation.
AGRICULTURAL LAND MANAGEMENT ACTIVITIES
Those methods and procedures used in the cultivation of land
in order to further crop and livestock production and conservation
of related soil and water resources.
APPLICANT
Any person, firm, or governmental agency who executes the
necessary forms to procure official approval of a project or a permit
to carry out construction of a project.
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. The various
types of BMPs are comprehensively included in the 2000 Maryland Stormwater
Design Manual.
CONCEPT PLAN
The first required plan that includes the information necessary
to allow an initial evaluation of a proposed project.
DEPARTMENT
The Queen Anne's County Department of Public Works or the
Queen Anne's County Soil Conservation District acting under written
agreement with and authorization from the County Commissioners of
Queen Anne's County.
[Amended 8-25-2015 by Ord. No. 15-08]
DESIGN MANUAL
The 2000 Maryland Stormwater Design Manual, and all subsequent
revisions, that serve as the official guide for stormwater management
principles, methods, and practices.
DIRECT DISCHARGE
The concentrated release of stormwater to tidal waters or
vegetated tidal wetlands from new development or redevelopment projects
in the Critical Area.
DISTRICT
The Queen Anne's Soil Conservation District.
EASEMENT
A grant or reservation by the owner of land for the use of
such land by others for a specific purpose or purposes, and, which
must be included in the conveyance of land affected by such easement.
ENVIRONMENTAL SITE DESIGN (ESD)
Using 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. Methods for designing ESD practices are specified in the
Design Manual.
EXEMPTION
Those land development activities that are not subject to
the stormwater management requirements contained in this chapter.
FINAL STORMWATER MANAGEMENT PLAN
The documents submitted for the last required plan reviews
that include the information necessary to allow all approvals and
permits to be issued by the approving agency.
GRADING
Any act by which soil is cleared, stripped, stockpiled, excavated,
scarified, filled, or any combination thereof.
HYDROGRAPH
A graph showing variation in stage (depth) or discharge of
a stream of water over a period of time.
IMPERVIOUS AREA
Any surface that does not allow stormwater to infiltrate
into the ground.
IN-FILL DEVELOPMENT
Development that occurs on vacant lands within areas of existing
development that does not require subdivision approval.
INFILTRATION
The passage or movement of water into the soil surface.
LIMIT OF DISTURBANCE (LOD)
A boundary depicted on the approved plan within which a contractor
has to confine his construction activities.
MAXIMUM EXTENT PRACTICABLE (MEP)
Designing stormwater management systems so that all reasonable
opportunities for using ESD planning techniques and treatment practices
are evaluated and only where absolutely necessary, a structural best
management practice (BMP) is implemented.
PLANNING TECHNIQUES
A combination of strategies employed early in project design
to reduce the impact from development and to incorporate natural features
into a stormwater management plan.
REDEVELOPMENT
Any construction, alteration, or improvement performed on
sites where existing land use is commercial, industrial, institutional,
or multifamily residential and existing site impervious area exceeds
40%.
RETROFITTING
The implementation of ESD practices, the construction of
a structural BMP, or the modification of an existing structural BMP
in a previously developed area to improve water quality over current
conditions.
SITE
Any tract, lot, or parcel of land, or combination of tracts,
lots, parcels of land that 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.
SITE DEVELOPMENT PLAN
The documents submitted for the second of three required
plan reviews that include the information necessary to allow a detailed
evaluation of a proposed project.
STANDARD STORMWATER MANAGEMENT PLAN
A plan that is developed by the Department to be used by
the applicants with single-family residential lot projects to meet
the intent of this chapter.
STATE
The State of Maryland.
STORMWATER
Water that originates from a precipitation event.
STORMWATER MANAGEMENT PLAN
A set of drawings or other documents submitted by an applicant
as a prerequisite to obtaining a stormwater management approval, which
contains all of the information and specifications pertaining to a
proposed stormwater management system.
STORMWATER MANAGEMENT SYSTEM
Natural areas, ESD practices, stormwater management measures,
and any other structure through which stormwater flows, infiltrates,
or discharges from a site.
VARIANCE
The modification of the minimum stormwater management requirements
for specific circumstances such that strict adherence to the requirements
would not fulfill the intent of this chapter.
WAIVER
The reduction of stormwater management requirements for a
specific development on a case-by-case review basis.
WATERSHED
The total drainage area contributing runoff to a single point.
WATERSHED MANAGEMENT PLAN
A plan, prepared by the Department and approved by the Administration,
developed to identify and address specific concerns of a watershed.
The Department shall be responsible for the coordination and
enforcement of the provisions of this chapter.
For the purpose of this chapter, the following documents are
incorporated by reference:
A. The 2000 Maryland Stormwater Design Manual, Volumes I and II (Maryland
Department of the Environment, April 2000), and all subsequent revisions,
