Discussion and Review of Tiffin Municipal Code Revisions – Preparation for Setting the Public Hearing — Tiffin City Code - DRAFT

CHAPTER 170 SUBDIVISION REGULATIONS necessary to service the subdivision itself. Other subdivisions which connect with the systems shall on a prorata basis reimburse the City for the cost of the additional system, which shall service that subdivision and meet all City specifications. (2) The City’s inability to efficiently collect or treat wastewater may be grounds for rejection of a proposed subdivision. A proportional fee may be requested by the City, from the subdivider, to pay for the necessary upgrades in the sewer system. (3) The sewer system improvements shall, upon inspection, approval, and acceptance by the City, become the property of the City. (4) The subdivider must provide evidence of construction permits from the Iowa Department of Natural Resources and other applicable State and federal agencies prior to approval of the final plat. C. Stormwater System. The subdivider of land being platted shall install and construct a stormwater system adequate to serve the area, including anticipated extension of use to serve additional areas. The Stormwater system shall be constructed in compliance with Chapter 166. (1) The stormwater drainage system shall be separated and independent of any sanitary sewer system. The acceptable standard for sizing storm sewers is to be a five-year, 24-hour storm event or as specified under current design standards. (2) Under some circumstances the City may require, as a condition for approval of the plat, installation of a stormwater system that is larger than necessary to meet the needs of the platted area, but necessary to complete the City stormwater system as it relates to both the area being platted and other areas. In such event, the City shall pay on a prorata basis for the excess cost over that which is necessary to service the subdivision itself. Other subdivisions which connect with the systems shall on a prorata basis reimburse the City for the cost of the additional system, which shall service that subdivision and meet all City specifications. (3) Stormwater facilities shall be located in the road right-of-way where feasible, or in the perpetual unobstructed easements of appropriate width. (4) In the stormwater design phase, the subdivider shall study the effect of each subdivision on existing downstream drainage facilities outside the area of the subdivision. The subdivider’s drainage studies together with such other studies as shall be appropriate shall serve as a guide to needed improvements. Where it is anticipated that the additional runoff incident to the development of the subdivision will overload an existing downstream drainage facility, the Council may withhold approval of the subdivision until provision has been made for the recovery of the cost for the improvement of said potential condition in such sum as the Council shall determine. No subdivision shall be approved unless adequate drainage will be provided to an adequate drainage watercourse or facility. CODE OF ORDINANCES, TIFFIN, IOWA - 1836 -
