The City of Davison shall grant a storm water permit, which may impose terms and conditions in accordance with Section 1047.017, and which shall granted only upon compliance with each of the following requirements:
(a) The developer will engage in the following sequence of events:
(1) Pre-Development Information Gathering. For all applicable projects, developers will contact representatives from each of the following: the County Road Commission, Health Department, municipal officials (zoning, planner, engineer, DPW, building official), and Drain Commissioner’s office (Water and Waste Services and Surface Water). The purpose will be to gather information on design standards, development guidelines, and to identify the type of information developers and their representatives must furnish to comply with this chapter. In some instances it may be expedient to hold one conference with all the involved parties.
(2) Development and Review of Conceptual Site Plan. Review of the conceptual site plan for approval at the County level by the appropriate personnel in Water and Waste Services, soil erosion, surface water, the Road Commission and the Health Department. Comments are returned to the owner/client and designer. At this time the design engineer will submit a statement that this site has been reviewed and determined sufficient to accommodate soil erosion and soil conservation measures.
(3) Coordinated Review and Approval. Review of the Storm Water Plan and the proposed BMPs will occur at the same time as the review of the site plan by representatives from the appropriate agencies.
(4) Municipal Review and Approval. Developers shall provide a storm water plan for post-construction management of storm water to the Municipality for review and approval. Guidance will be provided to zoning administrators and local planning commission members on the ordinance and design standards and they will be provided with a checklist for reference during site plan review. At this stage all necessary permits should have been applied for from Federal, State, and County agencies. Once all of the above documents have been obtained a building permit will be issued by the Municipality.
(5) The developer has submitted a storm water plan complying with Section 1047.011.
(6) The storm water plans contain adequate storm water BMPs to address the requirements laid out in the Genesee County Storm Water Standards & Requirements (GCSWS&R). At a minimum the developer will have to satisfy one of the following conditions:
A. A permanent on-site storm water system that includes on-site detention of storm water runoff (see Genesee County Storm Water and Flood Control Design Standard Requirements for requirements), and
B. A direct connection for all storm water runoff that will be discharged from and through the development site (see GCSWS&R/BMP Requirement Manual for requirements); or
C. 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 (see GCSWS&R/BMP Requirement Manual for requirements).
(7) The developer has paid or deposited the storm water permit review fee pursuant to Section 1047.013.
(8) The developer has paid or posted the applicable financial guarantee pursuant to Section 1047.014.
(9) The developer provides all easements necessary to implement the approved storm water plan and to otherwise comply with this chapter including, but not limited to, Section 1047.101. All easements shall be acceptable to the Municipality in form and substance and shall be recorded with the Genesee County Register of Deeds.
(11) All storm water runoff facilities shall be designed in accordance with the then-current BMPs.
(12) 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 storm water plan and this chapter. The maintenance agreement shall be acceptable to the City of Davison in form and substance and at minimum contain the requirements outlined in Sections 1047.100 through 1047.103.
