(a) Requirement. A developer may not undertake any development or land disturbance that is subject to the provisions of this title without an approved stormwater management plan.
(b) Preparation. A stormwater management plan shall be prepared by a design professional, according to the requirements of the State Code for the type of stormwater management plan required.
(1) ESD Planning Techniques and Practices. Stormwater management plans shall demonstrate that environmental site design (ESD) has been implemented to the maximum extent practicable (MEP) using the ESD Planning Techniques and Practices in COMAR 26.17.02.08B, the Design Manual, and the County Procedures Manual.
(2) Contents and submission of stormwater management plans. The developer shall be responsible for submitting phased stormwater management plans for development projects according to the comprehensive review and approval process in COMAR 26.17.02.09E and the County Procedures Manual including, but not limited to, the concept plan, stormwater management site development plan, the final stormwater management plan, and an operations and maintenance plan.
(c) Review. The Department shall review the stormwater management plan to determine whether the plan meets the requirements of this title and give notification of approval or reasons for disapproval. For single lot development in the critical area, the Office of Planning and Zoning shall review the stormwater management plan to determine whether the plan meets the requirements of this title and give notification of approval or reasons for disapproval. In granting approval of a stormwater management plan, the Office of Planning and Zoning or the Department may impose such conditions as it considers necessary to ensure compliance with the provisions of this title and the preservation of the public health and safety.
(d) Additional approvals required. If the stormwater management plan includes stormwater management practices that require small pond approval, a stormwater management plan shall be approved by the MDE and by the Anne Arundel Soil Conservation District.
(e) Easements, right-to-discharge, and other property interests. If a stormwater management plan involves direction or relocation of some or all of the stormwater runoff from the site in a manner that materially alters the flow characteristics of depth, velocity, width, or rate, or concentrates the discharge, a developer shall obtain from abutting and adjacent property owners any necessary easement, right-to-discharge, or other property interest concerning flow of water. This does not relieve the developer from obtaining any necessary easements, right-to-discharge, or other property interest concerning flow of water from adjacent property owners.
(f) Summary sheet. The plan shall include a summary sheet that lists the types of practices being utilized, their street location and addresses, the grid coordinates in NAD 83, and the size of the drainage area being treated.
