§ 56.64 POST-CONSTRUCTION STORMWATER POLLUTION PREVENTION PLAN.
   (A)   SWQMP requirements established in §§ 56.20 through 56.33 of this chapter shall be amended to include review of a Post-Construction Stormwater Pollution Prevention Plan (SWPPP). The post-construction SWPPP shall include the following information:
      (1)   A description of the proposed land use including amount of impervious area, directly connected impervious area and nature of the development;
      (2)   Location, dimensions, detailed specifications and construction details of all post-construction stormwater quality best management practices (BMPs), as defined in the city guidance documents;
      (3)   A sequence describing when each post-construction stormwater quality BMP will be installed; and
      (4)   A long-term operation and maintenance agreement containing maintenance guidelines for all post-construction stormwater quality measures to facilitate their proper long-term function. This agreement shall be made available to future parties, including property owners, who will assume responsibility for the operation and maintenance of the post-construction stormwater quality measures.
   (B)   The post-construction SWPPP shall include provisions for buffers.
      (1)   The waterway buffer will be used to define areas where land disturbance activities shall be permitted, but construction of any building or structure shall not be permitted.
      (2)   A waterway buffer shall be applied to all waterways serving more than 25 acres of tributary area or presented on a United State Geological Survey map as a blue line stream.
      (3)   Automatic exemptions are granted so long as, erosion prevention and sediment control, water quality and cut-fill policies are adequately addressed. Exemptions shall be granted for:
         (a)   Roads and utilities crossing waterways; and
         (b)   Pedestrian trails and walkways proximate to waterways.
      (4)   The waterway buffer shall be defined as the area contained within a boundary established 25 feet beyond the floodplain boundary as defined by FEMA or city master planning or 50 feet from the top of waterway bank as defined by geomorphic shape (not by the current water surface elevation); whichever is larger.
      (5)   The waterway buffer and floodplain may be used for application of water quality devices. This may only be permitted if erosion prevention and sediment control, water quality and cut-fill policies are adequately addressed as determined by the city according to the provisions of this subchapter.
   (C)   A licensed professional engineer in the State of Indiana shall stamp all construction plans and long-term maintenance documentation. This shall include all proposed improvements or modifications to existing or new stormwater infrastructure and other related improvements or modifications.
