A. 
For any proposed development not exempt under § 281-5, the owner shall submit phased stormwater management plans or waiver application to the enforcement authority for review and approval. At a minimum, plans shall be submitted for the sketch plan, preliminary and final stormwater management construction phases of project design. Each plan submittal shall include the minimum content specified in § 281-14 of this chapter and meet the requirements of the Stormwater Design Manual and Article III of this chapter.
B. 
The enforcement authority 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), Critical Area Commission, Technical Advisory Committee and the Planning Commission. All comments from the enforcement authority and other appropriate agencies shall be addressed and approval received at each phase of project design before subsequent submissions.
(1) 
Major projects shall not receive approval for each phase earlier than 45 days after a complete application is received by the enforcement authority.
(2) 
The approved final stormwater management plan shall serve as the basis for all subsequent construction.
C. 
Notification of approval or reasons for disapproval or modification shall be given to the owner. If a decision is not made within 90 days, the owner 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 on the plan of the dated signature of the enforcement authority.
D. 
For sites with minimal improvements, such that ESD to the MEP is clearly met based upon the sketch plan review, the Town Engineer has the discretion to delete the preliminary development phase and move directly to the final development phase. This determination will be made at the sketch site plan review phase.
A. 
The owner shall submit a sketch plan that provides sufficient information for an initial assessment of the proposed project and whether stormwater management can be provided according to § 281-11 of this chapter and the Stormwater Design Manual. Plans submitted for sketch plan approval shall include but are not limited to:
(1) 
A map at a scale specified by the enforcement authority showing site location, existing natural features, water and other sensitive resources, topography, and natural drainage patterns;
(2) 
The anticipated location of all proposed impervious areas, buildings, roadways, parking, sidewalks, utilities, and other site improvements;
(3) 
The location of the proposed limit of disturbance, erodible soils, steep slopes, and areas to be protected during construction;
(4) 
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;
(5) 
A narrative that supports the sketch plan design and describes how ESD will be implemented to the MEP; and
(6) 
Any other information required by the enforcement authority that is consistent with the preliminary nature of sketch plan submittals and is not specifically required to be submitted at a later approval stage under Subsections B through E of this section.
B. 
Following sketch plan approval by the enforcement authority, the owner/developer shall submit preliminary plans that reflect comments received during the previous review phase. Plans submitted for preliminary plan approval shall be of sufficient detail to allow site development to be reviewed and include but are not limited to:
(1) 
All information provided during the sketch plan review phase;
(2) 
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;
(3) 
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;
(4) 
A narrative that supports the preliminary plan design and describes how ESD will be used to meet the minimum control requirements, accompanied by sufficient technical data and information to establish that the proposed ESD may feasibly be implemented. Where structural stormwater management measures are proposed, applicant shall provide sufficient technical data and information to satisfy the enforcement authority that the minimum control requirements cannot be satisfied with ESD employed to the MEP or that the structural stormwater management measures offer merely redundant protection that is not necessarily required to achieve compliance with this chapter and provides other aesthetic or desirable features or benefits; and
(5) 
Any other information required by the enforcement authority that is consistent with the level of detail required in preliminary plan submittals and is not specifically required to be submitted at a latter approval stage under Subsections C through E of this section, unless such information is necessary to establish the feasibility of proposed ESD or to establish that ESD cannot be used to meet the minimum control requirements.
C. 
Following preliminary plan approval by the enforcement authority, 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:
(1) 
Final erosion and sediment control plans shall be submitted according to COMAR 26.17.01.05; and
(2) 
Final stormwater management plans shall be submitted for approval in the form of construction drawings and shall be accompanied by a report that includes sufficient information to evaluate the effectiveness of the proposed runoff control design.
D. 
Reports submitted for final stormwater management plan approval shall include but are not limited to:
(1) 
Geotechnical investigations, including soil maps, borings, site specific recommendations, infiltration tests and any additional information necessary for the final stormwater management design;
(2) 
Drainage area maps depicting predevelopment and post-development runoff flow path segmentation and land use;
(3) 
Hydrologic computations of the applicable ESD and unified sizing criteria according to the Stormwater Design Manual for all points of discharge from the site;
(4) 
Hydraulic and structural computations for all ESD practices and structural stormwater management measures to be used;
(5) 
A narrative that supports the final stormwater management design;
(6) 
Downstream analysis as required by § 281-11E; and
(7) 
Any other information required by the enforcement authority.
E. 
Construction drawings submitted for final stormwater management plan approval shall include but are not limited to:
(1) 
A vicinity map;
(2) 
Existing and proposed topography and proposed drainage areas, including areas 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) 
An easement plat, rights-of-way plat and ESD components, structural SMP facilities with applicable description. Maintenance responsibilities shall be defined;
(6) 
The delineation, if applicable, of the one-hundred-year floodplain and any on-site wetlands;
(7) 
Structural and construction details, including representative cross sections 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 ESD and unified sizing criteria volumes required in the Stormwater Design Manual;
(12)

(17) 
Any other information required by the enforcement authority; and
(18) 
Easement plan for individual stormwater management components on private or common property.
F. 
If a stormwater management plan involves the direction or redirection of some or all runoff from the site, a change in stormwater runoff volume, and/or a change in the nature of such runoff, it is the responsibility of the owner to obtain from adjacent property owners, including Talbot County or the State of Maryland, any easements of necessary property interests concerning flowage of water. Approval of a stormwater management plan does not create or affect any right to change the location, volume or other nature of stormwater runoff from the site onto adjacent property without the permission of the property owner.
G. 
Only a decision by the enforcement authority on the final stormwater plan shall be subject to judicial review, unless the applicant abandons a project as the result of a decision of the enforcement authority on a sketch plan or a preliminary plan.
A. 
The design of stormwater management plans shall be prepared by any individual whose qualifications are acceptable to the enforcement authority. The enforcement authority requires that the design be prepared and sealed by a professional engineer. All plats to be recorded shall be prepared by a professional land surveyor. All landscaping plans for ESD shall be prepared by a licensed landscape architect. All professionals shall be licensed in the state, as necessary to protect the public or the environment.
B. 
If a stormwater SMP requires either a dam safety permit from MDE or small pond approval from the Talbot Conservation District, the enforcement authority shall require that the design be prepared by a professional engineer licensed in the state.
