For any proposed development, the owner/developer shall submit phased stormwater management plans to the Town of Bel Air for review and approval. At a minimum, plans shall be submitted for the concept, site development, and final stormwater management construction phases of project design. Each plan submittal shall include the minimum content specified in § 405-13 of this chapter and meet the requirements of the Design Manual and Article II of this chapter.
The Town of Bel Air shall perform a comprehensive review of the stormwater
management plans for each phase of site design. Coordinated comments
will be provided for each plan phase that reflects input from all
appropriate agencies including but not limited to the soil conservation
district (SCD) and the departments of Planning, Zoning, and Public
Works of the Town of Bel Air. All comments from the Town of Bel Air
and other appropriate agencies shall be addressed and approval received
at each phase of project design before subsequent submissions.
The owner/developer shall submit a concept plan that provides sufficient information for an initial assessment of the proposed project and whether stormwater management can be provided according to § 405-10 of this chapter and the Design Manual. Plans submitted for concept approval shall include, but are not limited to:
A map at a scale specified by the Town of Bel Air showing site location,
existing natural features, water and other sensitive resources, topography,
and natural drainage patterns;
Preliminary estimates of stormwater management requirements, the
selection and location of ESD practices to be used, and the location
of all points of discharge from the site;
Following concept plan approval by the Town of Bel Air, the owner/developer
shall submit site development plans that reflect comments received
during the previous review phase. Plans submitted for site development
approval shall be of sufficient detail to allow site development to
be reviewed and include but not be limited to:
Final site layout, exact impervious area locations and acreages,
proposed topography, delineated drainage areas at all points of discharge
from the site, and stormwater volume computations for ESD practices
and quantity control structures;
A proposed erosion and sediment control plan that contains the construction
sequence, any phasing necessary to limit earth disturbances and impacts
to natural resources and an overlay plan showing the types and locations
of ESD and erosion and sediment control practices to be used;
A narrative that supports the site development design, describes
how ESD will be used to meet the minimum control requirements, and
justifies any proposed structural stormwater management measure; and
Following site development approval by the Town of Bel Air, the owner/developer
shall submit final erosion and sediment control and stormwater management
plans that reflect the comments received during the previous review
phase. Plans submitted for final approval shall be of sufficient detail
to allow all approvals and permits to be issued according to the following:
Final stormwater management plans shall be submitted for approval
in the form of construction drawings and be accompanied by a report
that includes sufficient information to evaluate the effectiveness
of the proposed runoff control design.
Geotechnical investigations, including soil maps, borings, site-specific
recommendations, and any additional information necessary for the
final stormwater management design;
Existing and proposed topography and proposed drainage areas, including
areas necessary to determine downstream analysis for proposed stormwater
management facilities;
Structural and construction details, including representative cross
sections for all components of the proposed drainage system or systems,
and stormwater management facilities;
If a stormwater management plan involves direction of some or all
runoff off of the site, it is the responsibility of the developer
to obtain from adjacent property owners any easements or other necessary
property interests concerning flowage of water. Approval of a stormwater
management plan does not create or affect any right to direct runoff
onto adjacent property without that property owner's permission.
The design of stormwater management plans shall be prepared by any
individual whose qualifications are acceptable to the Town of Bel
Air. The Town of Bel Air may require that the design be prepared by
either a professional engineer, professional land surveyor, or landscape
architect licensed in the state, as necessary to protect the public
or the environment.
If a stormwater BMP requires either a dam safety permit from MDE
or small pond approval from the Harford County Soil Conservation District
(SCD), the Town of Bel Air shall require that the design be prepared
by a professional engineer licensed in the state.
