(A) The Town of James Island Stormwater Program Permitting Standards and Procedures Manual (“Manual”) may include design standards, procedures, and criteria for conducting hydrologic, hydraulic, pollutant load evaluations, and downstream impact for all components of the stormwater management system. It is the intention of the Manual to establish uniform design practices; however, it neither replaces the need for engineering judgment nor precludes the use of information not submitted. Other accepted engineering procedures may be used to conduct hydrologic, hydraulic, and pollutant load studies if approved by the Stormwater Manager.
(B) The Manual will contain at a minimum the following components:
(1) Construction activity application contents and approval procedures;
(2) Construction completion and closeout processes;
(3) Hydrologic, hydraulic, and water quality design criteria (i.e., design standards) for the purposes of controlling the runoff rate, volume, and pollutant load. Suggested reference material shall be included for guidance in computations needed to meet the design standards;
(4) Information and requirements for new and re-development projects in special protection areas necessary to address TMDLs, known problem areas and other areas necessary to protect, maintain, and enhance water quality and the environment of the town and the public health, safety, and general welfare of the town’s residents;
(5) Construction document requirements;
(6) Long-term maintenance and maintenance plan;
(7) Minimum easement requirements; and
(8) Required and recommended inspection schedules and activities for all components of the stormwater management system, including construction-related BMPs.
(C) The Manual will be updated periodically to reflect advances in technology and experience.
