process. In addition, the owner/developer shall submit stormwater
management plans for each phase of the plan review process to all
members of the Technical Advisory Committee, which includes, but is
not limited to, the Cecil County Department of Planning and Zoning,
Cecil Soil Conservation District, Cecil County Health Department,
the citizens representative, and, if applicable, the Maryland State
Highway Administration and the planning offices of the incorporated

C.
Review by Soil Conservation District.
(1)
The Cecil Soil Conservation District (CSCD) may provide stormwater
management technical assistance, plan review and approval and construction
inspection of projects which meet all of the following criteria:
(a)
The parcel on which the project occurs is assessed as agricultural
use per the Tax Property Article of the Annotated Code of Maryland,
§ 8-209;
(b)
The parcel on which the project occurs is larger than 10 acres;
(c)
The parcel on which the project occurs has a current soil and
water quality conservation plan which is being implemented; and

In order for the proposed agricultural activity to be reviewed by
the CSCD, a technical assistance request form must be submitted by
the property owner and approved by the CSCD. If the CSCD determines
that the proposed agricultural activity does not meet the above criteria
or that the CSCD does not have the necessary resources to provide
technical assistance, the proposed agricultural activity must meet
all requirements for review and approval by the Department of Public
Works.

shall be informed of the status of the review process and the anticipated
completion date. The stormwater management plan shall not be considered
approved without the inclusion of the signature and date of signature
of an authorized representative of the Department of Public Works
on the plan.
[Amended 11-13-2012 by Ord. No. 2012-12]
G.
The owner/developer shall resubmit plans in a timely manner throughout
the three phases of the plan review process. If the Department of
Public Works has not received the plan submittal addressing the Department's

requesting an extension within 180 working days (from the date comments
are provided), the County will purge the files and the owner/developer
will be required to resubmit the project at the beginning of the stormwater
management review process for the phase for which the project has
not received Department of Public Works' approval. All fees shall
be assessed accordingly. Letters requesting an extension of the resubmission
time line shall be reviewed independently for each project and any
mitigating factors will be taken into account by the Department of
Public Works prior to rendering a decision. After reviewing the request,
the Department of Public Works may grant an extension for a maximum
of 180 working days. An extension may be granted beyond the initial
extension at the discretion of the Department of Public Works.
The developer is responsible for submitting a stormwater management
plan and a narrative for each phase of the plan review process that
meets the design requirements of this chapter. The narrative and plans
submitted shall provide the necessary information to ensure that all
significant natural resources have been mapped and protected, all
opportunities to enhance natural areas have been explored, impervious
area minimized, nonstructural practices used, and the use of alternative
surfaces explored. Microscale practices should be used to capture
and treat runoff and structural practices may only be used when all
options for the use of environmental site design have been exhausted.
The developer shall certify on the final stormwater management plans
that all clearing, grading, drainage, construction, and development
shall be conducted in strict adherence with the plan. The developer
must submit a plan that under proposed development conditions maintains
the existing drainage patterns for each individual drainage area.
All reasonable efforts, utilizing ESD to the MEP, must be made to
avoid the redirection of runoff from a particular drainage area to
another drainage area. The minimum information for each phase of the
stormwater management plan approval process submitted for approval
shall include, but is not limited to, the following:

map unit description for each soil type, the hydrologic soil group,
drainage class, hydric rating, depth to water table, unified soil
classification and parent material name;
(7)
If the proposed site consists predominately of C and D soils, a preliminary
geotechnical study may be required to determine the location and feasibility
of proposed ESD practices. It will be the responsibility of the design

(u)
If any stormwater management measures are proposed to act as
sediment control devices during site construction, the plan must include
details for the conversion from sediment control phase to stormwater
management phase, with a note indicating that the timing of conversion
must be approved by the Department of Public Works, but generally

(3)
If a stormwater management plan involves the direction or redirection
of some or all runoff off of the site, it is the responsibility of
the owner/developer to obtain from adjacent property owners any easement
or other necessary property interest concerning the discharge of water
prior to approval of the final stormwater management plan. Approval
of a stormwater management plan does not create or affect any right
to redirect and/or concentrate runoff onto an adjacent property without
that property owner's permission and the developer must secure
such permission at his cost.
A.
The design of stormwater management plans shall be prepared by any
individual permitted to do so by the specific State of Maryland law(s)
governing preparation of such plans. The Department of Public Works
may disapprove any stormwater management plan prepared by an individual
who does not provide proof of qualification and State of Maryland
professional licensure to prepare said plans. If a stormwater management
plan requires either a dam safety permit from Maryland Department
of the Environment or small pond approval from the Cecil County Soil
Conservation District, the Department of Public Works shall require
that the design be prepared by a professional engineer licensed in
the State of Maryland.
B.
A standard stormwater management plan for development on individual
single-family residential lots may be utilized if the project meets
all the limitations identified on the standard plan.
