Section 63-380 - Standard Plan for Erosion, Sediment and Stormwater Runoff Control

(1) All land disturbing activities under the jurisdiction of the Department must be performed in a manner that erosion is controlled and sediment is retained on the site concerned to the maximum extent feasible and stormwater is managed in a manner such that neither any significant on-site nor off-site damage and/or problem is caused or increased.

(2) All construction plans prepared by or for the Department must include designs to manage stormwater runoff and control erosion and sedimentation using state-of-the-art practices.

(3) Prior to the start of construction the contractor must submit in writing to the Engineer, for approval, his schedule for the accomplishment of temporary and permanent erosion and sediment control and stormwater management for the work to be performed.

(4) During construction, work must be scheduled and conducted in such a manner as to minimize soil erosion and control runoff, with particular attention to prevent contamination and depositing of sediment in adjacent streams, watercourses, lakes ponds and other water impoundments or onto adjacent properties, and to prevent on-site and off-site damage from stormwater runoff. Temporary and permanent measures to control erosion and sedimentation and manage stormwater runoff must be carried out in conjunction with clearing, grubbing and other earthwork operations and throughout the life of the project. Temporary measures such as berms, dikes, slope drains, terraces, earth rolls, sedimentation basins and temporary seeding must be provided until permanent drainage facilities and erosion control features are completed and operative. Permanent devices or measures such as culvert pipes, terraces gutters, bituminous curbs, permanent slope drains, riprap and permanent vegetation must be used and must be incorporated as soon as feasible.

(5) The Engineer's representative must periodically inspect work performed under the plan to insure that the necessary measures are implemented and are adequate for the needs of the site and affected off-site areas. The Department must require that additional measures be implemented in the event that the measures included in the plan are not sufficient to adequately control erosion and sedimentation and manage stormwater runoff.

(6) After a project has been completed and accepted in its entirety, the Department's Maintenance Forces must maintain the areas with top priority being to take the necessary steps to insure the continuance of proper erosion and sediment control and stormwater management measures as may be needed to prevent on-site and off-site damages or contamination of watercourse or impoundments.

(7) Each Resident Maintenance Engineer must prepare an inventory of existing erosion, sedimentation and stormwater problem areas. This list must be kept current and updated as conditions change. The Resident Maintenance Engineer, in conjunction with the District Office Personnel, must set priorities on the inventory and make the necessary corrections as time and funds permit.

(8) Maintenance must be performed in a manner that erosion is controlled and sediment is retained on the site to the maximum extent feasible and stormwater is managed in a manner such that neither any on-site nor off-site damage and/or problem is caused or increased. Existing vegetation must be retained and protected during maintenance to the maximum extent feasible.
