(a) For all development of undeveloped property, where the stormwater drainage discharges into a drainage ditch that is located within City rights-of-way, the developer shall be required to enclose the ditch in accordance with a plan approved by the City Engineer. This plan shall take into account the upstream drainage area flowing into the existing drainage ditch.
(b) The installation of sidewalks on developed or undeveloped lands shall include, where necessary, the installation of a storm sewer. The cost, as set forth in subsection (c) hereof, shall be included in the assessment for the sidewalk to be charged against the abutting property owner.
(c) The pipe shall be sized to carry at full-flow capacity the upstream drainage area for a 25-year, 24-hour storm event unless a smaller storm (10-year, 24-hour storm) is deemed acceptable by the City Engineer. If a smaller storm is deemed acceptable, provisions for additional stormwater storage may be needed. Calculations will be submitted and approved by the City Engineer.
(d) The cost of the pipe, up to twelve inches, and for bedding, backfill, yard drains and restoration material, shall be charged to the residential property owner. If a larger pipe is required, the additional cost shall be paid by the City. Costs paid by the City herein will be charged to Fund 271.

(f) Property owners installing or replacing a driveway over a stormwater drainage ditch within City rights-of-way shall meet City specifications and pay all costs for the installation of the storm sewer and an inspection fee.
