946.01 PURPOSE AND SCOPE.
   (a)   The purpose of this regulation is to establish technically feasible and economically reasonable storm water management standards to achieve a level of storm water quality and quantity control that will minimize damage to property and degradation of water resources and will promote and maintain the health, safety, and welfare of the citizens of the City of Sheffield Lake.
   (b)   This regulation requires owners who develop or re-develop their property within the City of Sheffield Lake to:
      (1)   Control storm water runoff from their property and ensure that all storm water management practices are properly designed, constructed, and maintained.
      (2)   Reduce water quality impacts to receiving water resources that may be caused by new development or redevelopment activities.
      (3)   Control the volume, rate, and quality of storm water runoff originating from their property so that surface water and ground water are protected and flooding and erosion potential are not increased.
      (4)   Minimize the need to construct, repair, and replace subsurface storm drain systems.
      (5)   Preserve natural infiltration and ground water recharge, and maintain subsurface flow that replenishes water resources, except in slippage prone soils.
      (6)   Incorporate storm water quality and quantity controls into site planning and design at the earliest possible stage in the development process.
      (7)   Reduce the expense of remedial projects needed to address problems caused by inadequate storm water management.
      (8)   Maximize use of storm water management practices that serve multiple purposes including, but not limited to, flood control, erosion control, fire protection, water quality protection, recreation, and habitat preservation.
      (9)   Design sites to minimize the number of stream crossings and the width of associated disturbance in order to minimize the City of Sheffield Lake's future expense related to the maintenance and repair of stream crossings.
      (10)   Maintain, promote, and re-establish conditions necessary for naturally occurring stream processes that assimilate pollutants, attenuate flood flows, and provide a healthy water resource.
   (c)   This regulation shall apply to all parcels used or being developed, either wholly or partially, for new or relocated projects involving highways and road; subdivisions or larger common plans of development; industrial, commercial, institutional, or residential projects; building activities on farms; redevelopment activities; grading; and all other uses that are not specifically exempted in the code.
   (d)   Public entities, including the State of Ohio, Lorain County, and the City of Sheffield Lake shall comply with this regulation for roadway projects initiated after March 10, 2006 and, to the maximum extent practicable, for projects initiated before that time.
   (e)   This regulation does not apply to activities regulated by, and in compliance with, the Ohio Agricultural Sediment Pollution Abatement Rules.
   (f)   This regulation does not require a Comprehensive Storm Water Management Plan for linear construction projects, such as pipeline or utility line installation, that do not result in the installation of impervious surface as determined by the Service Director.
(Ord. 25-11. Passed 5-24-11.)

   (d)   CLEAN WATER ACT: Pub. L. 92-500, as amended Pub. L. 95-217, Pub. L. 95-217, Pub. L. 95-576, Pub. L. 96-483, Pub. L. 97-117, and Pub. L. 100-4, 33 U.S.C. 1251 et. seq. Referred to as the Federal Water Pollution Control Act or the Federal Water Pollution Control Act Amendments of 1972.
   (e)   COMMUNITY: The City of Sheffield Lake, its designated representatives, boards, or commissions.
   (f)   COMPREHENSIVE STORM WATER MANAGEMENT PLAN: The written document and plans meeting the requirements of this regulation that sets forth the plans and practices to minimize storm water runoff from a development area, to safely convey or temporarily store and release post-development runoff at an allowable rate to minimize flooding and stream bank erosion, and to protect or improve storm water quality and stream channels.
   (g)   CRITICAL STORM: A storm that is calculated by means of the percentage increase in volume of runoff by a proposed development area. The critical storm is used to calculate the maximum allowable storm water discharge rate from a developed site.
   (h)   DETENTION FACILITY: A basin, pond, oversized pipe, or other structure that reduces the peak flow rate of storm water leaving the facility by temporarily storing a portion of the storm water entering the facility.
   (i)   DEVELOPMENT AREA: A parcel or contiguous parcels owned by one person or persons, or operated as one development unit, and used or being developed for commercial, industrial, residential, institutional, or other construction or alteration that changes runoff characteristics.
   (j)   DEVELOPMENT DRAINAGE AREA: A combination of each hydraulically unique watershed with individual outlet points on the development area.
   (k)   DISTURBED AREA: An area of land subject to erosion due to the removal of vegetative cover and/or soil disturbing activities.
   (l)   DRAINAGE: The removal of excess surface water or groundwater from land by surface or subsurface drains.
   (m)   EROSION: The process by which the land surface is worn away by the action of wind, water, ice, gravity, or any combination of those forces.
   (n)   EXTENDED CONVEYANCE: A storm water management practice that replaces and/or enhances traditional open or closed storm drainage conduits by retarding flow, promoting percolation of runoff into the soil, and filtering pollutants during the storm water quality event.
   (o)   EXTENDED DETENTION: A storm water management practice that replaces and/or enhances traditional detention facilities by releasing the runoff collected during the storm water quality event over at least 24 to 48 hours, retarding flow and allowing pollutants to settle within the facility.
   (p)   FINAL STABILIZATION: All soil disturbing activities at the site have been completed and a uniform perennial vegetative cover with a density of at least 80% coverage for the area has been established or equivalent stabilization practices, such as the use of mulches or geotextiles, have been employed.
   (q)   GRADING: The process in which the topography of the land is altered to a new slope.
   (r)   HYDROLOGIC UNIT CODE: A cataloging System developed by the United States Geological Survey and the Natural Resource Conservation Service to identify watershed in the United States.
   (s)   IMPERVIOUS COVER:    Any surface that cannot effectively absorb or infiltrate water. This may include roads, streets, parking lots, rooftops, sidewalks, and other areas not covered by vegetation.
   (t)   INFILTRATION: A storm water management practice that does not discharge to a water resource during the storm water quality event, requiring collected runoff to either infiltrate into the groundwater and/or be consumed by evapotranspiration, thereby retaining storm water pollutants in the facility.
   (u)   LARGER COMMON PLAN OF DEVELOPMENT: A contiguous area where multiple separate and distinct construction activities may be taking place at different times on different schedules under one plan.
   (v)   MAXIMUM EXTENT PRACTICABLE: The level of pollutant reduction that operators of small municipal separate storm sewer systems regulated under 40 C.F.R. Parts 9, 122, 123, and 124, referred to as NPDES Storm Water Phase II, must meet.
