'The City shall grant a storm water permit, which may impose terms and conditions in accordance with Section 1043.14 of this chapter, and which shall be granted only upon compliance with each of the following requirements:
(a) The developer has submitted a drainage plan complying with Section 1043.08 of this chapter.
(b) The drainage plan contains a description of an adequate, temporary storm water retention system to prevent construction site storm water runoff, satisfying the requirements of Section 1043.10 of this chapter, and the developer has obtained a soil erosion permit, if necessary.
(c) One of the following conditions is satisfied:
(1) The developer provides:
A. A permanent on-site storm water system sufficient to provide on-site detention of storm water runoff in a 25 year storm event; and
B. A direct connection for all storm water runoff that will be discharged from and through the development site in a 100 year storm event; or
(2) The developer provides a permanent on-site storm water system with a restricted outlet designed to result in no net increase in storm water runoff volume or rate onto any adjacent property in a 100 year storm event.
(d) The developer has paid or deposited the storm water permit review fee pursuant to Section 1043.09 of this chapter.
(e) The developer has paid or posted the applicable financial guarantee pursuant to Section 1043.11 of this chapter.
(f) The developer provides all easements necessary to implement the approved drainage plan and to otherwise comply with this chapter including, but not limited to, Section 1043.39 of this chapter. All easements shall be acceptable to the City in form and substance and shall be recorded with the Ionia County Register of Deeds.
(h) All storm water runoff facilities shall be designed in accordance with the then-current BMPs.
(i) The developer provides the required maintenance agreement for routine, emergency, and long-term maintenance of all storm water runoff facilities and in compliance with the approved drainage plan and this chapter including, but not limited to, Section 1043.40 of this chapter. The maintenance agreement shall be acceptable to the City in form and substance and shall be recorded with the Ionia County Register of Deeds.
(Ord. 07-2002-10. Passed 7-2-02.)
The developer shall provide a drainage plan to the City for review and approval by the City. The drainage plan shall identify and contain all of the following:
(a) The location of the development site and water bodies that will receive storm water runoff. Storm water discharges shall outlet within the same drainage basin or district where flow originates and generally may not be diverted to another drainage basin/district
(b) The existing and proposed topography of the development site, including the alignment and boundary of the natural drainage courses, with contours having a maximum interval of one foot (using USGS datum). The information shall be superimposed on the pertinent Ionia County soil map.
(c) The development tributary area to each point of discharge from the development.
(d) Calculations for the final peak discharge rates.
(e) Calculations for any facility or structure size and configuration.
(f) A drawing showing all proposed storm water runoff facilities with existing and final grades.
(g) The sizes and locations of upstream and downstream culverts serving the major drainage routes flowing into and out of the development site. Any significant off-site and on-site drainage outlet restrictions other than culverts should be noted on the drainage map.
(h) An implementation plan for construction and inspection of all storm water runoff facilities necessary to the overall drainage plan, including a schedule of the estimated dates of completing construction of the storm water runoff facilities shown on the plan and an identification of the proposed inspection procedures to ensure that the storm water runoff' facilities are constructed in accordance with the approved drainage plan.
(i) A plan to ensure the effective control of construction site storm water runoff and sediment track-out onto roadways.
(j) Drawings, profiles, and specifications for the construction of the storm water runoff facilities reasonably necessary to ensure that storm water runoff will be drained, stored, or otherwise controlled in accordance with this chapter.
(k) A maintenance agreement, in form and substance acceptable to the City, for ensuring maintenance of any privately-owned storm water runoff facilities. The maintenance agreement shall include the developer's written commitment to provide routine, emergency, and long-term maintenance of the facilities and, in the event that the facilities are not maintained in accordance with the approved drainage plan, the agreement shall authorize the City to maintain any on-site storm water runoff facility as reasonably necessary, at the developer's expense. Such agreement shall be signed prior to issuance of construction permits and shall be recorded on the deed for the property for perpetual maintenance.
(l) The name of the engineering firm and the registered professional engineer that designed the drainage plan and that will inspect final construction of the storm water runoff facilities. Should a storm water system, as built, fail to comply to the City's design and performance standards, it is the developer's responsibility to design and construct at his or her expense, any additional and/or alternative storm water management facilities. Such additional facilities shall be subject to approval by the City of Ionia.
(m) All design information must be compatible for conversion to City of Ionia Geographic Information System (CIGIS).
(n) Any other information necessary for the City to verify that the drainage plan complies with the City's design and performance standards for drains and storm water management systems.
(Ord. 07-2002-10. Passed 7-2-02.)
(a) Expenses, fees, and costs associated with processing, reviewing and approving or denying a storm water permit application shall be as established by the ICDC from time to time.
(b) At the time, a developer applies for a storm water permit, the developer shall deposit with the ICDC such sums as established by the ICDC including, without limitation, deposits into any required escrow account.
(Ord. 07-2002-10. Passed 7-2-02; Ord. 573. Passed 3-1-23.)
Prior to making any earth change on a development site regulated by this chapter, the developer shall first obtain a soil erosion permit issued in accordance with Part 91 of Act No. 451 of the Public Acts of 1994, as amended, if one is required. The developer shall install storm water runoff facilities and shall phase the development activities so as to prevent construction site storm water runoff and off-site sedimentation. During all construction activities on the development site, the City Engineer may inspect the development site to ensure compliance with the approved construction site runoff controls.
(Ord. 07-2002-10. Passed 7-2-02.)
Issuance of a storm water permit may be conditioned upon the developer submitting to the City, in a form and amount satisfactory to the City, a letter of credit or other financial guarantee for the timely and satisfactory construction of all storm water runoff facilities and site grading in accordance with the approved drainage plan. Upon certification by a registered professional engineer that the storm water runoff facilities have been completed in accordance with the approved drainage plan including, but not limited to, the provisions contained in Section 1043.08(h) of this chapter, the City may release the letter of credit, or other financial guarantee subject to final City acceptance and approval.
(Ord. 07-2002-10. Passed 7-2-02; Ord. 573. Passed 3-1-23.)
No certificate of occupancy shall be issued until storm water runoff facilities have been completed in accordance with the approved drainage plan; provided, however, the City may issue a certificate of occupancy if an acceptable letter of credit or other financial guarantee has been submitted to the City, for the timely and satisfactory construction of all storm water runoff facilities and site grading in accordance with the approved drainage plan.
(Ord. 07-2002-10. Passed 7-2-02.)
Storm water runoff facilities, after construction and approval, shall be maintained in good condition, in accordance with the approved drainage plan, and shall not be subsequently altered, revised or replaced except in accordance with the approved drainage plan, or in accordance with approved amendments or revisions in the plan.
