of another grading unit; and
[5]
Prior to the removal of sediment control practices.
(i)
Certification by the owner/developer that any clearing, grading,
construction, or development will be done pursuant to the approved
erosion and sediment control plan. The certification must also require
that the responsible personnel involved in the construction project
have a certificate of training at an MDE approved training program
for the control of erosion and sediment prior to beginning the project.
The certificate of training for responsible personnel may be waived
by the District on any project involving 4 or fewer residential lots.
Additionally, the owner/developer shall allow right of entry for periodic
on-site evaluation by the District, the Department, and/or MDE.
(j)
Certification by a professional engineer, land surveyor, landscape
architect, architect, or forester (for forest harvest operations only)
registered in the state that the plans have been designed in accordance
with erosion and sediment control laws, regulations, and standards,
if required by the District or the administration.
(9) Any additional information or data deemed appropriate by the District
and/or the Department.
Fees for technical and engineering review, inspection
and enforcement activities shall be as established by law.
[Amended by Bill No. 12-57]
If, in the opinion of the Director, the nature
of the work is such that it may create a hazard to human life or endanger
adjoining property or property at a higher or lower elevation or any
street or street improvement or any other public property, then the
Director may, before issuing the grading permit, require that the
applicant for a grading permit file a certificate of insurance showing
that the applicant is insured against claims for damages for personal
injury and property damage in an amount not less than $100,000, including
damage to the County by deposit or washing of material onto County
streets or other public improvements, which may arise from or out
of the performance of the work, whether such performance be by the
applicant, their subcontractor or any person directly or indirectly
employed by the applicant, and the amount of such insurance shall
be prescribed by the Director in accordance with the nature of the
risks involved. Such insurance shall be written by a company licensed
to do business in the state and approved by the County. Neither issuance
of a grading permit nor compliance with the provisions hereto or any
condition imposed by the Department shall relieve any person from
any responsibility for damage to persons or property otherwise imposed
by law nor impose any liability upon the County for damage to persons
or property. Failure to maintain the required liability insurance
shall automatically operate as a temporary revocation of any and all
grading permits issued by Harford County to the grading permit holder
or their predecessors or successors and assigns in interest.
The Director may, where deemed necessary to
protect the property or health, safety or general welfare of other
persons or the public in general, require the grading permit holder
to post a maintenance bond or other approved security in the form
and manner acceptable to the County, for a period of 12 months following
the completion of the land-disturbing activities for which the grading
permit was issued. The security shall cover latent defects in labor
and/or material required to maintain all grade surfaces, walls, drains,
dams, structures, slopes, vegetation and sediment control measures
and other protective devices and damages resulting from construction
equipment and vehicles doing work in that portion of the area covered
by the terms of the grading permit. The amount of the security shall
be equal to or greater than 10% of the construction cost, as determined
by the Director.
[Added by Bill No. 12-57]

[Amended by Bill No. 10-11]
[Amended by Bill No. 10-11]
The provisions of this article shall be applicable
to any site with new development or redevelopment activity. The stormwater
management measures must be designed consistent with the Design Manual,
the rules and regulations and USDA Natural Resources Conservation
Service Maryland Conservation Practice Standard Pond Code 378 (January
2000) and revisions, as applicable, and constructed according to an
approved plan or the provisions of the redevelopment section of this
article.
[Amended by Bill No. 10-11]
A. Stormwater management plans are required by the Department for all redevelopment, unless otherwise specified by watershed management plans developed according to §
214-28F of this article. Stormwater management plans for redevelopment shall be consistent with the Design Manual, the rules and regulations and Maryland 378 Specs (as required).
B. All redevelopment
project designs shall reduce impervious areas within the limit of
disturbance (LOD) by at least 50% as calculated using the Design Manual.
Where site conditions prevent the reduction of impervious area, stormwater
management practices shall implement ESD to the MEP to provide water
quality treatment for at least 50% of the existing impervious area
within the LOD. When a combination of impervious area reduction and
ESD implementation is used, the combined area shall be at least 50%
of the existing site impervious area.
C. Alternative stormwater management measures may be used to meet the requirements in §
214-29B of this article if the applicant satisfactorily demonstrates to the Department that impervious area reduction has been maximized and ESD has been implemented to the MEP. Alternative stormwater management measures include, but are not limited to:
(1) An
on-site structural BMP.
(2) Off-site
structural BMP to provide water quality treatment for an area equal
to or greater than 50% of the existing impervious area.
(3) A combination
of impervious area reduction, ESD implementation and on-site or off-site
structural BMP for an area equal to or greater than 50% of the existing
site impervious area within the LOD.
D. Harford County may develop separate policies for providing water quality treatment for redevelopment projects if the requirements of §
214-29B cannot be met. These policies in the following order of preference may include, but not be limited to:
(1) Retrofitting
of an existing stormwater management system to meet the current design
criteria and that compensates for the lack of treatment provided at
the site.
(2) Use
of an approved stormwater management banking site within the same
watershed. Criteria for debiting the bank for projects utilizing the
site shall be developed by the Department for each banking site. A
stormwater management permit must be issued prior to utilizing the
banking site and provisions must be made for the maintenance of the
facility.
(3) Watershed
or stream restoration at sites identified and approved by the Department
to reduce the pollutant loading comparable to that which would be
required of the proposed project. The scope and specific practices
used in the restoration effort must be reviewed and approved by the
Department and must comply with all applicable local, state and federal
permit requirements and regulations.
(4) Other
practices approved by the Department and the Administration, including
pollution trading with another entity.
[Amended by Bill No. 11-24]
(5) Fees
in lieu of quality control in the amount of $1.00 per square foot
of impervious area when physical constraints do not allow implementation
of a stormwater management system.
E. Money
collected as fees in lieu under this subsection shall be deposited
into a separate account and shall be used only to fund the investigation,
design, construction, acquisition of easements or property or maintenance
of projects for quantitative or qualitative stormwater management
or stream restoration.
F. Stormwater
management shall be addressed according to the new development requirements
in the Design Manual for any net increase in impervious area.
[Amended by Bill No. 10-11]
The Department may grant a written variance
from any requirement of stormwater management criteria of this article
if there are exceptional circumstances applicable to the site such
that strict adherence will result in unnecessary hardship and not
fulfill the intent of the article. A variance may not be granted based
solely on financial hardship. A written request for variance shall
be provided to the Department and shall state the specific variances
sought and reasons for their granting. The Department shall not grant
a variance unless and until sufficient justification is provided by
the person developing land that the implementation of ESD to the MEP
has been investigated thoroughly.
[Amended by Bill No. 10-11]
A. Minimum control requirements.
(1) The minimum control requirements established in this
section and the Design Manual are as follows:
(a)
The County shall require that the planning techniques,
nonstructural practices and design methods specified in the Design
Manual be used to implement ESD to the MEP. The use of ESD planning
techniques and treatment practices must be exhausted before any structural
BMP is implemented. Stormwater management plans for development projects
subject to this article shall be designed using ESD sizing criteria,
recharge volume, water quality volume and channel protection storage
volume sizing criteria according to the Design Manual. The MEP standard
is met when channel stability is maintained, predevelopment groundwater
recharge is replicated, nonpoint source pollution is minimized and
structural stormwater management practices are used only if determined
to be absolutely necessary. Control of the 10-year frequency storm
event is required according to the Design Manual except for residential
lots greater than 2 acres which access onto existing roads and where
impervious surfaces are designed to drain and discharge in a nonerosive
erosive manner.
(b)
The Department may require more than the minimum
control requirements specified in this article if hydrologic or topographic
conditions warrant or if flooding, stream channel erosion or water
quality problems exist downstream from a proposed project.
(2) Alternative minimum control requirements may be adopted
by the Department subject to Administration approval. The Administration
shall require a demonstration that alternative requirements will implement
ESD to the MEP and control flood damages, accelerated stream erosion,
water quality and sedimentation. Comprehensive watershed studies may
also be required.
(3) Stormwater
management and development plans, where applicable, shall be consistent
with adopted and approved watershed management plans or flood management
plans as approved by the Maryland Department of the Environment in
accordance with the Flood Hazard Management Act of 1976.
B. Stormwater management measures. The ESD planning techniques and practices
and structural stormwater management measures established in this
article shall be used either alone or in a combination, in developing
a stormwater management plan. The applicant shall demonstrate that
ESD has been implemented to the MEP before the use of a structural
BMP is considered in developing the stormwater management plan.
(1) ESD planning techniques and practices.
(a)
The following planning techniques shall be applied according to the Design Manual to satisfy the applicable control requirements established in Subsection
A of this section:
[1]
Preserving and protecting natural resources;
[2]

[3]
Minimizing impervious area;
[5]
Using ESD practices to maintain 100% of the annual predevelopment
groundwater recharge volume;
[6]
Using green roofs, permeable pavement, reinforced turf and other
alternative surfaces;
[7]
Limiting soil disturbance, mass grading and compaction;
[8]
Clustering development; and
[9]
Any practice approved by the Administration.
(b)
The following ESD treatment practices shall be designed according to the Design Manual to satisfy the applicable minimum control requirements established in Subsection
A of this section:
[1]
Disconnection of rooftop runoff;
[2]
Disconnection of non-rooftop runoff;
[3]
Sheetflow to conservation areas;
[5]
Submerged gravel wetlands;
[11] Swales and meandering channels;
[13] Any practices approved by the administration.
(c)
The use of ESD planning techniques and treatment practices specified
in this section shall not conflict with existing state law or the
County Code, County regulations or policies.
(2) Structural stormwater management measures.
(a)
The following structural stormwater management practices shall be designed according to the Design Manual and the rules and regulations to satisfy the applicable minimum control requirements established in Subsection
A of this section:
[1]
Stormwater management ponds;
[2]

[3]
Stormwater management infiltration;
[4]
Stormwater management filtering systems; and
[5]
Stormwater management open channel systems.
(b)
The performance criteria specified in the Design Manual and
the rules and regulations with regard to general feasibility, conveyance,
pretreatment, treatment and geometry, environment and landscaping
and maintenance shall be considered when selecting structural stormwater
management practices.
(c)
Structural stormwater management practices shall be selected
to accommodate the unique hydrologic or geologic regions of the County.
(3) Easements and maintenance agreements necessary for the ESD planning techniques and treatment practices and structural stormwater management measures used to satisfy the minimum requirements in Subsection
B of this section must be recorded in the land records of Harford County. The practices shall remain unaltered by subsequent property owners unless prior approval is obtained from the Department.
(4) Alternative ESD planning techniques and treatment practices and structural
stormwater management practices may be used for new development runoff
control if they meet the performance criteria established in the Design
Manual and all subsequent revisions and are approved by the Administration.
Practices used for redevelopment projects shall be approved by the
Department.
(5) For the purpose of modifying the minimum control requirements or
design criteria, the applicant shall submit to the Department an analysis
of the impacts of stormwater flows downstream in the watershed. The
analysis shall include hydrologic and hydraulic calculations necessary
to determine the impact of hydrograph timing modifications of the
proposed development upon a dam, highway, structure or natural point
of restricted stream flow. The point of investigation is to be established
with the concurrence of the Department downstream of the first downstream
tributary whose drainage area equals or exceeds the contributing area
to the project or stormwater management facility.
C. Specific design criteria. The basic design criteria, methodologies
and construction specifications, subject to the approval of the Department
and the Administration, shall be those of the Design Manual and the
rules and regulations. For all land within the Edgewood Enterprise
Zone, the stormwater management requirements for landscaping shall
also include the following as acceptable plantings: crabapples (Malus
'prairie fire'); red spire pear (Pyrus calleryana 'red spire'); and
sugar tyme crab (Malus 'sugar tyme').
D. The use
of an off-site facility for channel protection volume (cpv), overbank
flood protection volume (qp) and extreme flood volume (qf) is acceptable
provided the site has implemented ESD to the MEP according to the
Design Manual and the runoff is conveyed to the off-site facility
via a closed storm drain or similarly engineered system. It is not
acceptable to subject natural stream systems to erosive conditions
for conveying unmanaged stormwater runoff to downstream regional facilities.
The engineer shall submit proof that the facility was designed to
control runoff from the proposed development in question and that
the facility has the capacity to control the additional runoff caused
by the proposed development in question. An agreement allowing such
use of an off-site facility shall be executed between the developer
and the owner of the off-site facility and shall be recorded in the
land records of Harford County.
[Amended by Bill No. 10-11]
A. Review and approval of stormwater management plans.
(1) For any proposed development, the applicant shall submit phased stormwater management plans or a waiver application to the Department for review and approval, unless otherwise exempted. At a minimum, plans shall be submitted for the stormwater management concept, site development and final stormwater management construction phases of project design. Each plan submittal shall include the minimum content specified in Subsection
B of this section and meet the requirements of the Design Manual and §
214-31 of this article. The Department shall perform a comprehensive review of the plans for each phase of site design to determine compliance with the requirements of this article. Coordinated comments will be provided for each phase that reflect input from the District and the Department of Planning and Zoning. All comments from the Department, the District and the Department of Planning and Zoning shall be addressed and included in subsequent submissions unless the project meets the requirements set forth in Subsection
A(2). The plans shall serve as the basis for all subsequent construction.
(2) Certain projects may be submitted under an abbreviated review process
that includes only the concept and final plan phases and will not
be required to provide the stormwater management site development
plan; however, the required information shall be included in the final

(5) In granting any permit, the Department may attach
such conditions thereto as may be deemed reasonably necessary to ensure
public health and safety and the mitigation of environmental impact.
Fees for technical and engineering review, inspection
and enforcement activities shall be as established by law.
[Amended by Bill No. 10-11]
If, in the opinion of the Department, the nature
of the work is such that it may create a hazard to human life or endanger
adjoining property, property at a higher or lower elevation, streets,
street improvements or any other property, then the Department may
require a certificate of insurance. The certificate of insurance (if
required) shall be submitted to the Department prior to issuance of
the stormwater management permit. The insurance shall cover claims
for damages for property damage and personal injury, in an amount
not less than $100,000, which may arise from or out of the performance
of the work, whether such performance is by the applicant, the applicant's
subcontractor or any person directly or indirectly employed by the
applicant. The amount of such insurance shall be prescribed by the
Department in accordance with the nature of the risks involved. Neither
issuance of a permit nor compliance with the provisions hereto or
any condition imposed by the Department shall relieve any person from
any responsibility for damage to persons or property otherwise imposed
by law or impose any liability upon the County for damages to persons
or property. Failure to maintain the required liability insurance
shall automatically operate as a temporary revocation of any and all
permits issued by Harford County to the permittee or the permittee's
predecessors or successors and assigns in interest.
[Amended by Bill No. 10-11]
Prior to the issuance of a stormwater management

214-37.
(8) Inspections shall be conducted in accordance with the Design Manual,
rules and regulations or COMAR 26.17.02.10 (whichever is more restrictive).
The Department may, for enforcement purposes, use any one or a combination
of the following actions:
