§ 53.022 APPLICATIONS FOR APPROVAL.
   (A)   Concept plan and consultation meeting. Before a Storm Water Management Permit application is deemed complete, the developer shall schedule a consultation with the Storm Water Administrator on a concept plan for the post-construction storm water management system to be utilized in the proposed development project. This consultation meeting should take place at the time of the preliminary plan of subdivision or other early step in the development process. The purpose of this meeting is to discuss the post-construction storm water management measures necessary for the proposed project, as well as to discuss and assess constraints, opportunities and potential approaches to storm water management designs before formal site design engineering is commenced. Local watershed plans, the Unified Development Ordinance and other relevant resource protection plans should be consulted in the discussion of the concept plan. To accomplish this goal, the following information should be included in the concept plan, which should be submitted in advance of the meeting.
      (1)   Existing conditions/proposed site plans. Existing conditions and proposed site layout sketch plans, which illustrate at a minimum: existing and proposed topography, perennial and intermittent streams, mapping of predominant soils from soil surveys (if available), boundaries of existing predominant vegetation; proposed limits of clearing and grading and location of existing and proposed roads, buildings, parking areas and other impervious surfaces.
      (2)   Natural resources inventory. A written or graphic inventory of the natural resources at the site and surrounding area as it exists prior to the commencement of the project. This description should include a discussion of soil conditions, forest cover, geologic features, topography, wetlands and native vegetative areas on the site, as well as the location and boundaries of other natural feature protection and conservation areas such as lakes, ponds, flood plains, stream buffers and other setbacks (e.g., drinking water well setbacks, septic setbacks and the like). Particular attention should be paid to environmentally sensitive features that provide particular opportunities or constraints for development and storm water management.
      (3)   Storm Water Management System Concept Plan. A written or graphic concept plan of the proposed post-development storm water management system including preliminary selection and location of proposed structural storm water controls, low-impact design elements, location of existing and proposed conveyance systems such as grass channels, swales and storm drains, flow paths, location of flood plain/floodway limits, relationship of site to upstream and downstream properties and drainages and preliminary location of any proposed stream channel modifications, such as bridge or culvert crossings.
   (B)   Storm Water Management Permit application. The storm water management permit application shall detail how post-development storm water runoff will be controlled and managed and how the proposed project will meet the requirements of this chapter, including §§ 53.040 through 53.043. All such plans shall be prepared by a qualified registered North Carolina professional engineer and the engineer shall perform services only in his or her area of competence, and shall verify that the design of all storm water management facilities and practices meets the submittal requirements for complete applications, that the designs and plans are sufficient to comply with applicable standards of this chapter and policies found in the Design Manual, and that the designs and plans ensure compliance with this chapter. The submittal shall include all of the information required in the submittal checklist established by the Storm Water Administrator. Incomplete submittals shall be treated pursuant to § 53.021(E).
   (C)   As-built plans and final approval.
      (1)   Upon completion of a project, and before a certificate of occupancy shall be granted, the applicant shall certify that the completed project is in accordance with the approved storm water management plans and designs, and shall submit actual “as built” plans for all storm water management facilities or practices after final construction is completed. Electronic versions of the “as-built” plans shall accompany any hard copy submittal of plans.
      (2)   The plans shall show the final design specifications for all storm water management facilities and practices and the field location, size, depth and planted vegetation of all measures, controls and devices, as installed. The designer of the storm water management measures and plans shall certify, under seal, that the as-built storm water measures, controls and devices are in compliance with the approved storm water management plans and designs and with the requirements of this chapter. A final inspection and approval by the Storm Water Administrator shall occur before the release of any performance securities.
   (D)   Other permits. No certificate of compliance or occupancy shall be issued by the Cabarrus County Commerce Department without final as-built plans and a final inspection and approval by the Storm Water Administrator, except where multiple units are served by the storm water practice or facilities, in which case the Cabarrus County Commerce Department may elect to withhold a percentage of permits or certificates of occupancy until as-built plans are submitted and final inspection and approval has occurred.
