(a) Anne Arundel County or the City of Annapolis may issue a grading or building permit within the Severn River Watershed only after the developer submits a plan of development approved by the soil conservation district. If the development plan contains any septic or private sewer facility, the Department of the Environment shall approve it only if the facility will not contribute in any way to pollution of the Severn River. The developer shall submit a certificate from a professional engineer, a professional land surveyor, or a licensed landscape architect stating that the developer’s plan to control silt and erosion is adequate to contain the silt and erosion on the property covered by the plan. Also, the developer shall submit another certificate stating that any construction or development will be done according to the plan. A subdivision developer shall obtain approval of the plan at the time of approving and recording of the subdivision plat. In addition to any other penalty provided in this subtitle, if a developer violates his certificate, then every permit issued pursuant to the certificate is void.
(b) A State, county, or municipal road, building, or structure may not be constructed, relocated, or enlarged within the Severn River Watershed until plans have been submitted to and approved by the soil conservation district.
