(B) Policy statement. It shall be the policy and requirement of Howard County and the Howard County Drainage Board that the storage and controlled release of stormwater runoff shall be required for any new development, redevelopment and new construction located within the County Area and not exempt under division (D) below if this section. No improvement location permit shall be issued by the Howard County Plan Commission for the construction or extension of any proposed or existing building in the County Area until the drainage plans and calculations required under division (C) below have been approved by resolution of the Drainage Board.
(C) Standards and allowable release rates. The developer shall submit to the Howard County Surveyor, acting on behalf of the Drainage Board, plans and calculations in the form and content set out in Exhibit A attached to Ordinance 2019-BCCO-27 and incorporated herein. Such plans and calculations shall demonstrate to the satisfaction of the Drainage Board compliance with the Stormwater Requirements set forth on said Exhibit A. The Surveyor shall refer the plans and calculations to the Howard County Stormwater District for review and validation. In the event the Stormwater District, in its sole discretion, chooses to outsource such review and validation to a professional engineer, the professional fees incurred shall be paid by the Stormwater District.
