(a) Requirements Generally. All property being developed except single family residential within the City, 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 City Manager, 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 with a maintenance plan and responsibilities 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 specified for manholes, inlets, catch basins, pipes, ditch, head 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 Specification:, except that no new open drainage ditches shall be permitted, without the approval of the City Engineer, City Manager and Planning Commission.
(Ord. 2017-09. Passed 6-6-17.)
(3) The City Manager, prior to issuing the certificate of zoning compliance, shall refer the drainage plan submitted to the City Engineer for approval.
(4) The fee for drainage plan review shall be $125.00 if the lot is less than one and one half acres and an additional $75.00 for each additional one half acre.
(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 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 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 City Engineer with any additions, corrections or deletions made by him shall be considered the approved plan. Any Developer who disagrees with the determination of the City Engineer may file an appeal with the Planning and Zoning Commission upon payment of an appeal fee in the amount of $200.00. 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.
(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 downspout 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 dwelling.
