(a) The purpose of this chapter is to establish technically feasible and economically reasonable stormwater management standards to achieve a level of stormwater 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 Warren:
(b) The regulations described in this chapter require owners who develop or redevelop their property within the City of Warren to:
(1) Control storm water runoff from their property and ensure that all Storm water Control Measures (SCMs) 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 groundwater 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 groundwater recharge, and maintain subsurface flow that replenishes water resources, except in slippage prone soils.
(6) Incorporate stormwater 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 stormwater management.
(8) Maximize use of stormwater control measures 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 water resource crossings and the width of associated disturbance in order to minimize the City of Warren's future expenses related to the maintenance and repair of water resource 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) The regulations in this chapter shall apply to all parcels used or being developed, either wholly or partially, for new or relocated projects involving highways and roads; 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.
(d) Public entities, including the State of Ohio, Trumbull County, and the City of Warren shall comply with this chapter for linear projects within public rights-of way (e.g. roadway and sidewalk projects).
(e) These regulations do not require a Post-Construction Stormwater Control 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 City of Warren Water Pollution
Control Department or Ohio EPA. Such projects must be designed to minimize the number of water resource crossings and the width of disturbance. Linear construction projects must comply with the requirements of Chapter 938 Erosion and Sediment Control.
(f) The Post-Construction Stormwater Control Plan developed to meet the requirements of this chapter shall be coordinated and submitted with the Stormwater Pollution Prevention Plan (SWP3) or Abbreviated SWP3 that are developed for the same site to meet the
requirements of Chapter 938 Erosion and Sediment Control. These plans shall also be coordinated with any other plans under the jurisdiction of Warren WPC that are required
by the City of Warren Codified Ordinances. These plans shall be titled and numbered in one consecutive sequence to make a Comprehensive Storm Water Management Plan for the site.
