(a) Requirements Generally. All property being developed except single family residential and residential lots under one-half acre, shall now be required to comply with the following requirements:
(1) The developer, person, contractor or company which is developing said property shall submit to the Zoning Administrator, when making application for a Zoning Permit, a plan prepared by a licensed engineer in the State of Ohio showing the design of a storm water drainage system to provide for the adequate movement and disposal of subsurface and surface water.
(2) All design aspects and criteria for hydrology and hydraulics shall be governed by the latest edition of "Standard Drainage Criteria Manual" for Trumbull County, Ohio, except as may be modified herein. All construction and materials specifications for manholes, inlets, catch basins, pipes, ditch linings, headwalls, culverts and bridges shall be governed by the appropriate sections of the latest edition of the State of Ohio, Department of Transportation, "Construction and Materials Specifications", except that no new open drainage ditches shall be permitted, without the approval of the Planning Commission.
(3) The Zoning Administrator, prior to issuing the Zoning Permit, shall refer the drainage plan submitted to the City Engineer for approval if needed.
(4) The fee for drainage plan review shall be one hundred dollars ($100.00).
(5) The drainage plan shall provide that all sump pump and roof drain connections shall not outlet on the ground or through the curb but shall be connected to the pipe system, either directly or through the use of a collection system. No storm drainage, including foundation drains, shall be permitted to discharge into sanitary sewers.
(6) The drainage plan shall in each case be designed to provide a facility large enough to accommodate potential run-off from its entire upstream drainage area, whether inside or outside the property being developed. The plan will also study the effect of each construction on existing downstream drainage facilities outside the area of construction. Where it is anticipated that the additional run-off incident to the development of the property will overload an existing downstream drainage facility, approval may be withheld until the provision has been made for the improvement of such potential condition. When a proposed drainage system will carry across private land outside of the proposed development, appropriate drainage rights must be secured and recorded.
(7) The plan approved by the Zoning Administrator with any additions, corrections or deletions made by him shall be considered the approved plan. Any Developer who disagrees with the determination of the Zoning Administrator may file an appeal with the Planning and Zoning Commission upon the payment of an appeal fee in the amount of one hundred dollars ($100.00). The Planning and Zoning Commission will hold a public hearing following normal appeal procedures and shall make a determination which shall be final.
(8) The approved plan shall become a condition of zoning compliance and the facilities contained in the plan shall be constructed prior to the property being occupied.
(9) The drainage plan shall also contain provision for an Erosion and Sediment Control Plan that shall adhere to all regulated activities, performance standards, application procedures and monitoring requirements as set forth in the latest edition of the “Trumbull County Erosion and Sediment Control Rules”, except as may be modified herein.
(b) Single Family Residential Requirements. All single family residential property being developed within the City shall now be required to comply with the following requirements:
(1) Drainage from sump pumps, roof drain connections and foundation drains shall not outlet onto the ground or through the curb into the street, but shall be connected to the storm water collection system. No storm drainage of any type shall be permitted to be discharged into sanitary sewers or combination sewers.
(2) Where an adequate storm water collections system is not available, drainage from sump pumps, roof drain connections and foundation drains shall be detained to leach beds with at least one half cubic yard of washed gravel per down spout and one cubic yard per sump pump. Such leach bed shall be located at least ten (10) feet from any lot line.
(3) This section does not apply to additions, either attached or unattached, to any existing single family dwellings.
(4) Comply with Erosion and Sediment Control for single lots as set forth in the latest edition of the “Trumbull County Erosion and Sediment Control Rules”, except as may be modified herein.
