SOIL EROSION AND SEDIMENT CONTROL PLAN
(A) All soil erosion and sediment control plans shall meet the requirements of the Standards and Specifications.
(B) A developer shall prepare and submit a design for review and approval process for three different phases of project planning commonly identified as the concept, site development, and final plans for erosion and sediment control.
(1) Concept plan. The concept phase of project review and approval requires all the concept phase sediment control plan checklist items be addressed and at a minimum mapping of natural resources, vegetative buffer strips, highly erodible soils, and slopes 15% and steeper.
(2) Site development or preliminary subdivision plan. The site development and preliminary plan shall address review agency comments on the concept plan in full, and include a narrative describing how erosion and sediment control will be integrated into the SWM strategy using ESD in accordance with the Design Manual. The plan must address all the construction drawing sediment control plan checklist items and show stormwater, erosion, and sediment control practices.
(3) Final plan (Mylars). The final plan shall address all review agency comments related to the site development or preliminary subdivision plan. Final erosion and sediment control plans must at a minimum include the limit of disturbance, the location of each sediment control practice, associated construction notes, details, and sequence of construction.
(2004 Code, § 121-15) (Ord. 2012-09, passed 12-11-2012; Ord. 2018-10, passed 11-29-2018)
(A) The applicant shall submit a soil erosion and sediment control plan prepared in accordance with plan requirements stated in COMAR 26.17.01 and in compliance with § 152.050 and any supporting computations to the District for review and approval. The soil erosion and sediment control plan shall contain sufficient information to describe how soil erosion and off site sedimentation will be minimized. The District shall review the plan to determine compliance with this chapter, the Standards and Specifications, and any other applicable state laws and regulations prior to approval. The plan shall serve as a basis for all subsequent construction.
(B) The plan must include the “Standard Stabilization Note” on the plan stating:
“Following initial soil disturbance or redisturbance, permanent or temporary stabilization must be completed within:
(1) Three calendar days as to the surface of all perimeter dikes, swales, ditches, perimeter slopes, and all slopes steeper than three horizontal to one vertical (3:1); and
(2) Seven calendar days as to all other disturbed or graded areas on the project site not under active grading.”
(C) Certification by the owner/developer that any clearing, grading, construction, or development will be done pursuant to the approved erosion and sediment control plan.
(D) In approving the plan, the District may impose such conditions as may be deemed necessary to ensure compliance with the provisions of this chapter, COMAR 26.17.01, the Standards and Specifications, and to preserve public health and safety.
(E) The District shall notify the applicant of approval or reasons for the disapproval or modification after submission of the completed soil erosion and sediment control plan. The soil erosion and sediment control plan may not be considered approved without the inclusion of the signature and date of signature approval by the District on the plan.
(F) Approved plans shall become void three years from the date of approval. The District may extend the approval beyond three years at the request of the applicant. Such approval may be subject to division (G) below.
(G) Grandfathering conditions consistent with Maryland Department of the Environment regulations include the following:
(1) After January 9, 2013, the District will only approve new plans adhering to the Standards and Specifications.
(2) After January 9, 2013, all plans must adhere to the stabilization practices found in the Standards and Specifications regardless of when the sediment and erosion control plan was approved. Plan revisions for this specific requirement will not be necessary. However, when a plan revision is submitted to the District for any other purpose, the plan must also incorporate the updated stabilization requirements.
(3) Revisions to previously approved grading and sediment control plans and plan requests for time extension approvals that are submitted after January 9, 2013, must address the Standards and Specifications.
(4) After January 9, 2015, if the grading activities for an approved sediment and erosion control plan have not started, said plans must be revised to meet the Standards and Specifications in order for the District approval to remain valid. All other conditions noted above still apply.
(2004 Code, § 121-16) (Ord. 2012-09, passed 12-11-2012; Ord. 2018-10, passed 11-29-2018)
(A) Major modifications of the approved plans shall be submitted to the District, processed in the same manner as the original plan, and prepared in accordance with § 152.051. Major modifications shall occur when:
(1) Field inspection or evaluation of the plan has revealed the inadequacy of the plan to accomplish soil erosion and sediment control objectives; or
(2) Due to changed circumstances or for other reasons, the approved plan cannot be effectively carried out.
(B) The county may require the installation of emergency soil erosion and sediment control measures to protect stream channels, other properties, or the general public from damage. The approved plan must be revised to reflect these or other measures per this section. Emergency measures will remain in effect until modifications or revisions to the plan are approved and implemented.
(C) Minor field modifications may be authorized by the county, provided that the modifications are consistent with the requirements of this chapter, regulations, and the Standards and Specifications. The county and the District shall establish a list of approved field modifications for this purpose. The list of field modifications shall be approved by the Maryland Department of the Environment, and available in the county and the District.
(2004 Code, § 121-17) (Ord. 2012-09, passed 12-11-2012)
The District may grant a written variance from the design requirements of the Standards and Specifications for exceptional circumstances such that strict adherence to the Standards and Specifications will result in unnecessary hardship and not fulfill the purpose of this chapter. The applicant shall submit a written request for a variance to the District with specific reasons and supporting documentation.
(2004 Code, § 121-18) (Ord. 2012-09, passed 12-11-2012)
GRADING PLAN
(A) Notification of approval or reasons for the disapproval or modification of a proposed grading plan shall be given to the applicant by the county after submission of the completed grading plan.
(B) The grading plan shall specify all areas where controlled fill or other materials approved by the Maryland Department of the Environment shall be placed. Waste of any kind, including construction debris and organic material, may not be buried on the site but shall be properly managed during the project and disposed of at a licensed facility.
(2004 Code, § 121-19) (Ord. 2012-09, passed 12-11-2012)
