§ 19-22. Watershed management plans.

(a) The Department of Environmental Protection, in cooperation with the Department, the Board, and other appropriate agencies, may develop watershed management plans to implement stormwater management policies that apply individually to specific watersheds in the County. Each watershed management plan should:

(1) include detailed hydrologic and hydraulic analyses to determine hydrograph timing;

(2) evaluate stormwater quantity and quality, and base flow and groundwater management needs;

(3) include a cumulative impact assessment of watershed development;

(4) identify existing flooding, receiving stream channel, water quality, biological resources, and habitat conditions;

(5) specify the types of stormwater management, stream restoration and wetlands protection practices to be implemented;

(6) identify specific opportunities for stormwater retrofit, stream and wetlands restoration, and groundwater recharge;

(7) specify where the Director may grant waivers of on-site stormwater management controls;

(8) be consistent with the Design Manual’s General Performance Standards for Stormwater Management in Maryland; and

(9) be approved by the Administration.

(b) The Board should prepare functional master plans under Division II of the Land Use Article of the Maryland Code to preserve, conserve, and manage natural resources in each of the County’s watersheds for the County Council’s review and approval. Each functional master plan should address land use, impervious impact on streams and waterways, stream buffers, wildlife and stream habitat, forest preservation, and other issues related to the permitting of stormwater management facilities and the development of watershed management plans.
