(a) The purpose of this regulation 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.
(b) This regulation requires owners who develop or re-develop their property within the City to:
(1) Control stormwater runoff from their property and ensure that all stormwater 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 stormwater 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 ground water 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 SCMs 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’s future expenses 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 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 in this section.
(d) Public entities, including the State of Ohio, Lake County, and the City of Mentor on the 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 Stormwater 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 City Engineer. Such projects must be designed to minimize the number of stream crossings and the width of disturbance. Linear construction projects must comply with the requirements of this chapter.
