A.
For any proposed development, the developer shall submit
a stormwater management plan or waiver application to the Town Engineer for
review and approval, unless otherwise exempted. The stormwater management
plan shall contain supporting computations, drawings, and sufficient information
describing the manner, location, and type of measures in which stormwater
runoff will be managed from the entire development. The Town Engineer shall
review the plan to determine compliance with the requirements of this chapter
prior to approval. The plan shall serve as the basis for all subsequent construction.
B.
Notification of approval or reasons for disapproval or
modification shall be given to the applicant within 30 days after submission
of the completed stormwater plan. If a decision is not made within 30 days,
the applicant 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 the
Town Engineer on the plan.
A.
The developer is responsible for submitting a stormwater
management plan that meets the design requirements of this Ordinance. The
plan shall be accompanied by a report that includes sufficient information
to evaluate the environmental characteristics of affected areas, the potential
impacts of the proposed development on water resources, and the effectiveness
and acceptability of measures proposed for managing stormwater runoff. The
developer or builder shall certify on the drawings that all clearing, grading,
drainage, construction, and development shall be conducted in strict accordance
with the plan. 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 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
the property owner's permission.
[Amended 7-14-2003 by Ord. No. 247]
B.
The minimum information submitted for support of a stormwater
management plan or application for a waiver shall be as follows:
[Amended 7-14-2003 by Ord. No. 247]
(1)
A brief narrative description of the project;
(2)
Geotechnicial investigations, including soil maps, borings,
site specific recommendations, and any additional information necessary for
the proposed stormwater management design;
(3)
Descriptions of all watercourses, impoundments, and wetlands
on or adjacent to the site or into which stormwater directly flows;
(4)
Hydrologic computations, including drainage area maps
depicting predevelopment and post-development runoff flow path segmentation
and land use;
(5)
Hydraulic computations;
(6)
Structural computations;
(7)
Unified sizing criteria volume computations according
to the Design Manual; and
(8)
Any other information required by the Town Engineer.
C.
Construction drawings submitted for stormwater management
plan approval shall include the following:
(1)
A vicinity map;
(2)
A topography survey showing existing and proposed contours,
including the area necessary to determine downstream analysis for proposed
stormwater management facilities;
(3)
Any proposed improvements, including location of buildings
or other structures, impervious surfaces, storm drainage facilities, and all
grading;
(4)
The location of existing and proposed structures and
utilities;
(5)
Any easements and rights-of-way;
(6)
The delineation, if applicable, of the one-hundred-year
floodplain and any on-site wetlands;
(7)
Structural and construction details for all components
of the proposed drainage system or systems, and stormwater management facilities.
(8)
All necessary construction specifications;
(9)
A sequence of construction;
(10)
Data for total site area, disturbed area, new impervious
area, and total impervious area;
(11)
A table showing the unified sizing criteria volumes required
in the Design Manual;
(12)
A table of materials to be used for stormwater management
facility planting;
(13)
All soil boring logs and locations;
(14)
A maintenance schedule;
(15)
Certification by the owner/developer that all stormwater
management construction will be done according to this plan;
(16)
An as-built certification signature block to be executed
after project completion; and
(17)
Any other information required by the Town Engineer.
A.
The design of stormwater management plans shall be prepared
by any individual whose qualifications are acceptable to the Town Engineer.
The Town Engineer 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.
B.
If a stormwater BMP requires either a dam safety permit
from MOE or small pond approval from the Caroline County Soil Conservation
District (SCD), the Town Engineer shall require that the design be prepared
by a professional engineer licensed in the state.
