The Talbot County Department of Public Works.
A porous, water-bearing geologic formation generally restricted
to materials capable of yielding an appreciable supply of water.
A structural device or nonstructural practice designed to
temporarily store or treat stormwater runoff in order to mitigate
flooding and reduce pollution.
The volume used to design structural management practices
to control stream channel erosion. Methods for calculating the channel
protection storage volume are specified in the 2000 Maryland Stormwater
Design Manual.
The removal of trees, their stumps, and brush from the land
but shall not include the ordinary mowing of grass.
The first of three required plan approvals (concept, site
development and final) that includes the information necessary to
allow an initial evaluation of a proposed project.
Talbot County, Maryland.
The Director of the Talbot County Department of Public Works,
or an authorized representative of the Talbot County Department of
Public Works.
The 2000 Maryland Stormwater Design Manual, and all subsequent
revisions, that serves as the official guide for stormwater management
principles, methods, and practices.
A permanent structure for the temporary storage of runoff
which is designed so as not to create a permanent pool of water.
To change the runoff characteristics of a parcel of land
in conjunction with construction or alteration.
The concentrated release of stormwater to tidal waters or
vegetated tidal wetlands from new development or redevelopment projects
in the Critical Area.
That area contributing runoff to a single point measured
in a horizontal plane, which is enclosed by a ridgeline.
Using small-scale stormwater management practices, nonstructural
techniques, and better site planning to mimic natural hydrologic runoff
characteristics and minimizes the impact of land development on water
resources. Methods for designing ESD practices are specified in the
Design Manual.
Those land development activities that are not subject to
the stormwater management requirements contained in this chapter.
A stormwater design feature that provides gradual release
of a volume of water to increase settling of pollutants and protect
downstream channels from frequent storm events. Methods for designing
extended detention BMPs are specified in the Design Manual.
The storage volume required to control those infrequent but
large storm events in which overbank flows reach or exceed the boundaries
of the 100-year floodplain.
The last of three required plan approvals (concept, site
development and final) that includes the information necessary to
allow all approvals and permits to be issued by the approving agency.
Prolonging the flow time of runoff to reduce the peak discharge.
Any act by which soil is cleared, stripped, stockpiled, excavated,
scarified, filled, or any combination thereof.
The Talbot County Stormwater Management Process and Implementation
Guide.
Any surface that does not allow stormwater to infiltrate
into the ground.
The passage or movement of water into the soil surface.
To design a stormwater management system to exhaust all reasonable
opportunities to use ESD planning techniques and treatment practices,
and to use structural BMPs only where absolutely necessary.
The design and construction of a facility necessary to control
stormwater from more than one development.
The design and construction of systems necessary to control
stormwater within an immediate development.
The volume controlled by structural practices to prevent
an increase in the frequency of out-of-bank flooding generated by
development. Methods for calculating the overbank flood protection
volume are specified in the Design Manual.
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 other entity.
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.
Talbot County Department of Public Works.
That portion of the water quality volume used to maintain
groundwater recharge rates at development sites. Methods for calculating
the recharge volume are specified in the Design Manual.
Any construction, alteration, or improvement on sites where
existing land use is commercial, industrial, institutional, or multifamily
residential and existing site impervious area exceeds 40%.
A permanent structure that provides for the storage of runoff
by means of a permanent pool of water.
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.
Soils or other surficial materials eroded, transported or
deposited by the action of wind, water, ice, or gravity.
Any tract, lot, or parcel of land, or combination of tracts,
lots, parcels of land that are in single ownership, or are contiguous
and in separate ownership, where development is to be performed as
part of a unit, subdivision, or project.
The second of three required plan approvals (concept, site
development and final) that includes the information necessary to
allow a detailed evaluation of a proposed project.

structural practices and conveyance facilities and any other structure
through which stormwater flows, infiltrates, or discharges from a
site.

The modification of the minimum stormwater management requirements
for specific circumstances where strict adherence to the requirements
would result in unnecessary hardship and would not fulfill the intent
of this chapter.
The reduction of stormwater management requirements by the
County Engineer based upon specific circumstances of a development.
Any natural or artificial stream, river, creek, ditch, channel,
canal, conduit, culvert, drain, waterway, gully, ravine or wash, in

overflow or floodwater.
The volume needed to capture and treat 90% of the average
annual rainfall events at a development site. Methods for calculating
the water quality volume are specified in the Design Manual.
