   (A)   A storm water submittal package fulfilling the requirements of this section shall be completed and submitted to the City Civil Engineer for approval before a storm water permit can be obtained to accomplish a land alteration, unless the land alteration is such that a storm water permit can be obtained in accordance with § 5-2-6-12.
   (B)   The storm water submittal consists of four parts:  a storm water permit application; a storm water construction plan; a Technical Information Report (TIR); and, if applicable, a Storm Water Pollution Prevention Plan (SWPPP) and the required Notice Of Intent  (NOI).  A City of Indianapolis flood plain development permit is also required for developments within any Flood Control District regulated by the Flood Control District Zoning Ordinance of Marion County, Indiana, as amended.
   (C)   The storm water permit application shall be in such form and shall contain such information as required under regulations promulgated under § 5-2-6-37.
   (D)   The storm water construction plan must be submitted in duplicate, and shall indicate in a precise way the work to be accomplished pursuant to the storm water permit.  Such storm water construction plans shall contain information and design calculations as provided for in regulations promulgated under § 5-2-6-37 and be consistent with the articles of 327 I.A.C.-15.  Design calculations shall also conform to the standards of §§ 5-2-6-36 through 5-2-6-56.
      (1)   One copy of the storm water construction plan will remain on file with the City Civil Engineer.

      (3)   All storm water construction plans submitted under this section to the City Civil Engineer for approval must be certified by a registered professional engaged in storm drainage design under whose supervision the plans were prepared.  This Certificate of Sufficiency shall be in the form contained in regulations promulgated under § 5-2-6-37.
      (4)   All storm water plans submitted under this section to the City Civil Engineer must include a Certificate of Obligation to Observe by a registered professional engaged in storm drainage design unless such certificate is not required due to the provision of City construction inspection services in conformance with § 5-2-6-23.  This Certificate of Obligation to Observe shall be in the form contained in regulations promulgated under § 5-2-6-37.  The professional certifying the plan and the professional certifying the Certificate of Obligation to Observe can be the same individual.
      (5)   Plans for proposed activities:
         (a)   Requiring a specified flood protection grade in conformance with regulations promulgated under § 5-2-6-37 or, where applicable, the effective Flood Control Districts Zoning Ordinance of Marion County, Indiana; or
         (b)   Which involve land or watercourse alterations, as defined by the effective Flood Control Districts Zoning Ordinance of Marion County, Indiana; or

      (1)   The TIR must be sufficient to allow the City Civil Engineer to make a complete review of all pertinent hydrologic methodologies and results.
      (2)   The TIR shall contain a summary of all hydrologic and hydraulic calculations and results and descriptions of existing site conditions, identified neighborhood concerns, special problems encountered, computer or hand methodologies used, and any required downstream conditions and analysis.
   (F)   All single-family residential construction with land disturbing activities less than one acre shall employ, at a minimum, perimeter type erosion and sediment control practices in accordance with regulations promulgated under § 5-2-6-37.
   (G)   All non-single-family residential land disturbing activities of any size, and all single-family residential land disturbing activities that result in the disturbance greater than one acre of total land area, and which are not part of a larger common plan of development or sale, shall be required to have a Storm Water Pollution Prevention Plan (SWPPP).  The SWPPP shall contain such information and follow such minimum standards as are required under Rule 5 (327 I.A.C. 15-5) and regulations promulgated under § 5-2-6-37, except as noted below.  All non-residential construction must submit some form of SWPPP.
      (1)   If the owner or operator is required to submit a soil erosion control plan to the state under Rule 5 (327 I.A.C. 15-5), such plan shall be deemed to fulfill the requirements of this chapter.  Such plan and the required Notice of Intent shall be submitted to the City Civil Engineer in lieu of the SWPPP.
      (2)   The SWPPP should be presented in a format consistent with the articles of Rule 5 (327 I.A.C. 15-5) and should clearly portray the methods and means whereby erosion and sediment control measures are implemented.  Plan sheets shall not exceed 24-inch by 36-inch dimensions.
