All drawing submissions to MDOT MAA shall meet the requirements described in this section as well as Volume 1, Appendix 1D - CAD Standard.
The following drawings shall be included in plan sets as applicable.
3.1.1 MDE Standard Erosion and Sediment Control Notes and Details
Erosion and Sediment Control (ESC) drawings shall be provided for all MDOT MAA projects involving site work and earth disturbance, regardless of whether an MDE permit is required. MDOT MAA has established standardized Erosion and Sediment Control Notes, Details and Sequencing Sheets for all projects at BWI Marshall or Martin State Airports.

The Erosion and Sediment Control Package has been assimilated for use for all projects at BWI Marshall and Martin State Airports. The details used are from the Maryland Department of the Environment, Maryland Standards and Specifications for Erosion and Sediment Control, current edition. Vegetative Stabilization Notes used are from the Specifications for Performing Landscaping Activities for the Maryland Aviation Administration (Latest Edition).

1. Erosion and Sediment Control Notes 1
2. Erosion and Sediment Control Notes 2
3. Erosion and Sediment Control Plan (Border Sheet)
4. Erosion and Sediment Control Details 1
5. Erosion and Sediment Control Details 2
6. Erosion and Sediment Control Details 3
7. Erosion and Sediment Control Details 4
8. Erosion and Sediment Control Details 5
9. Vegetative Stabilization Notes
B. Details and requirements for use are to follow the information and guidelines from the following sources:
1. The Maryland Department of the Environment, Maryland Standards and Specifications for Erosion and Sediment Control (latest edition).
2. Specifications for Performing Landscaping Activities for MDOT MAA (Latest Edition), prepared by MDOT MAA Office of Environmental Services, Environmental Planning Section.
3. The Maryland’s Waterway Construction Guidelines prepared by the Maryland Department of the Environment Water Management Division issued September 1999 and revised November 2000.
4. The Maryland Stormwater Management and Erosion & Sediment Control Guidelines for State and Federal Projects, by the Maryland Department of the Environment, Water Management Administration, published February 2015.
3.1.1.1 Erosion and Sediment Control Notes 1
This is a standard sheet used in the Erosion & Sediment Control package and therefore no additional changes are required to this sheet.
3.1.1.2 Erosion and Sediment Control Notes 2
Standard Erosion and Sediment Control Note 26 (Site Information): This information varies with each contract and should be completed by the Consultant.
Total Areas for the Facility represents the total area for each airport as follows:
A. BWI Marshall = 3,200 Acres
B. Martin State = 775 Acres
C. Total Area of Project Site: Site Specific
D. Area Disturbed: Equivalent to Limits of Disturbance (LOD)
E. Area to be roofed or paved: Site Specific
F. Total Cut: Site Specific
G. Total Fill: Site Specific
H. Off-Site Waste/Borrow Area Location: If a location has been provided within the plans refer to respective plan sheet(s). If a location has not been determined, then add statement “TO BE DETERMINED”
1. Design Certification: Must be signed prior to MDE approval
2. Owner’s/Developer’s Certification: To be signed by MDOT MAA representative such as the MDOT MAA Project Manager
3. As-Built Certification Statement: To be signed by the Contractor at completion of the project (for SWM facilities only)
4. Sequence of Construction: A general sequence of construction has been provided on the sheet for both an Initial and Final Phase for Erosion and Sediment Control. The consultant is to provide the device information and a sequence at the locations where indicated “Designer To List Devices Used On Plans Here” and “Designer to Establish Sequencing Here”
Depending upon the complexity of the project, the Sequence of Construction shall be specific to the Construction Activity to take place. This may require additional line items which shall be numbered. Please note that on simplified projects a “Final Phase” may not be required. This will be determined on a project by project basis.
3.1.1.3 Erosion and Sediment Control Plan(s)
A. These plans will be specific for each project and may include more than one plan. Scales should meet MDOT MAA requirements.
B. The Sediment Control Legend is to remain on each plan sheet. Modifications can be made based upon project specifics and controls that are being used.
C. In some instances more detailed Sequence of Construction may be provided on these sheets as necessary.
3.1.1.4 Erosion and Sediment Control Details 1-8
A. Several sheets have been provided for use. The consultant is to use only the details required for the specific project. Other details not used may be removed.
B. If new or unique details are required, the consultant may add them to the detail sheet. Final approval for use will be made by MDE.
C. Any details not shown on these sheets and/or new details being provided should be provided to MDOT MAA for incorporation into the standardized sheets for future distribution.
3.1.1.5 Vegetative Stabilization Notes
This sheet reflects the information from the Specifications for Performing Landscaping Activities for the Maryland Aviation Administration and therefore no changes are required. However, if additional requirements are determined above and beyond requirements on this sheet, changes should be made to reflect these requirements.
3.1.1.6 Additional Erosion and Sediment Control Drawings
If required, the Consultant may be required to provide additional Plan, Detail, Note, and Sequencing sheets based upon complexity and size of the project.
3.1.2 Stormwater Management Plans
The Consultant shall ensure that the Stormwater Management Plans include As-Built certification, applicable SWM As-Built table(s), applicable SWM As-Built checklist and additional documentation, provided in accordance with MDE guidelines, electronically available at the following MDE weblinks:
Maryland Stormwater Management Guidelines for State & Federal Projects, April 15, 2010
Technical Memo No. 1 - Standard Items to Include on Erosion & Sediment Control Plans
Technical Memo No. 16 - As-built Submissions and Checklists
The Consultant shall ensure that the contract documents state that the Contractor is responsible for surveying, and providing the As-Built quantities, dimensions and elevations for the table of each SWM facility once construction has been completed. The Consultant shall convey through the contract documents that it is the responsibility of the contractor to provide the completed as-built certification package for each SWM facility in the contract. Refer to Section 1.2.1 Maryland Department of the Environment (MDE) Stormwater Management and Erosion and Appendix 4A - Standard Contract Drawings, General Stormwater Management Notes Sheet for submission requirements.
3.1.2.1 General Stormwater Management Notes Drawing
This is a standard sheet used in the Stormwater management package and therefore no additional changes are required to this sheet.
A. This sheet summarizes the requirements of the SWM facility As-Built certification which shall be completed for each facility on the contract.
B. The responsibilities of the Contractor are outlined as part of this plan sheet.
C. The As-Built Approval Checklist shall be completed for all facilities in the contract.
3.1.2.2 Procedure for SWM As-Built Certification
Deliverables shall be as described in Chapter 3 Deliverables.
The Consultant shall be responsible for including the General Stormwater Management Notes Sheet in the overall contract documents for the project.
The Consultant shall convey through the contract documents that it is the responsibility of the contractor to provide the completed as-built certification package for each SWM facility. The Contractor is responsible for submitting a complete As-Built Certification Package for each Stormwater facility to MDOT MAA Environmental Planning Section (EPS), which shall then be submitted by the Environmental Planning Section to MDE for final acceptance. If a project has multiple SWM facilities, the Contractor (while consulting with MDOT MAA) will review contract documents to determine if the As-Built certifications for each SWM facility will be submitted to MDOT MAA separately (once the facility is constructed) or collectively (at the close of the project).
