Review by Soil Conservation District.
(1) 
The Cecil Soil Conservation District (CSCD) may provide stormwater management technical assistance, plan review and approval and construction inspection of projects which meet all of the following criteria:
(a)

If the Department of Public Works has not received the plan submittal addressing the Department's comments or a letter from the developer or the developer's engineer requesting an extension within 180 working days (from the date comments are provided), the County will purge the files and the owner/developer will be required to resubmit the project at the beginning of the stormwater management review process for the phase for which the project has not received Department of Public Works' approval. All fees shall be assessed accordingly. Letters requesting an extension of the resubmission time line shall be reviewed independently for each project and any mitigating factors will be taken into account by the Department of Public Works prior to rendering a decision. After reviewing the request, the Department of Public Works may grant an extension for a maximum of 180 working days. An extension may be granted beyond the initial extension at the discretion of the Department of Public Works.
The developer is responsible for submitting a stormwater management plan and a narrative for each phase of the plan review process that meets the design requirements of this chapter. The narrative and plans submitted shall provide the necessary information to ensure that all significant natural resources have been mapped and protected, all opportunities to enhance natural areas have been explored, impervious area minimized, nonstructural practices used, and the use of alternative surfaces explored. Microscale practices should be used to capture and treat runoff and structural practices may only be used when all options for the use of environmental site design have been exhausted. The developer shall certify on the final stormwater management plans that all clearing, grading, drainage, construction, and development shall be conducted in strict adherence with the plan. The developer must submit a plan that under proposed development conditions maintains the existing drainage patterns for each individual drainage area. All reasonable efforts, utilizing ESD to the MEP, must be made to avoid the redirection of runoff from a particular drainage area to another drainage area.

The Department of Public Works may disapprove any stormwater management plan prepared by an individual who does not provide proof of qualification and State of Maryland professional licensure to prepare said plans. If a stormwater management plan requires either a dam safety permit from Maryland Department of the Environment or small pond approval from the Cecil County Soil Conservation District, the Department of Public Works shall require that the design be prepared by a professional engineer licensed in the State of Maryland.
B. 
A standard stormwater management plan for development on individual single-family residential lots may be utilized if the project meets all the limitations identified on the standard plan.
