(a) Grading Plan. A master grading plan shall be a part of required Comprehensive Stormwater Management Plan and Improvement Plans for all Major Subdivisions and may be required for other proposals. This grading plan shall show contour lines at two (2) foot intervals, with stormwater best management practice details at one (1) foot intervals. Elevations are to be based on the NAVD88, and the grading plan shall show:
(1) Existing and proposed contour lines.
(2) Yard swales.
(3) Minimum building envelope and other spot elevations.
(4) Lot layout and lot dimensions.
(5) Finished grade of streets.
(6) Stormwater management features and major storm routing path (if applicable, include fire pond).
(b) Comprehensive Storm Water Management Plan.
(1) SWPPP. When the Developer intends to remove or disturb the natural topsoil, trees, and other vegetation, and/or add impervious surfaces, or where the Developer intends to change the surface contour of a proposed Subdivision, he/she shall prepare a SWPPP and have such plan approved by the Summit Soil and Water prior to the commencement of earthwork. The SWPPP shall be included in the improvement drawings and the Stormwater Management Plan. In general, erosion and sediment control work will consist of phasing construction, minimizing disturbed areas, timely application of temporary and permanent seeding, and the installation of temporary structural erosion and post-construction best management sediment control practices as specified in Chapter 941 of the Codified Ordinances of the County of Summit. The SWPPP shall also include the design of permanent structural and non-structural post construction water quality practices their associated long term maintenance agreement. Summit Soil and Water has developed a check list to assist with the creation of the SWPPP which is included in Appendix L.
(2) Storm Water Management. When impervious surfaces are proposed for a development project, the Comprehensive Storm Water Management Plan shall include all structural and non-structural features that convey, detain, retain, infiltrate, and filter storm water runoff to manage and treat storm water runoff both as to quantity and quality from the development site as specified in Chapter 943 of the Codified Ordinances of the County of Summit and the Summit County Engineer's Stormwater Drainage Manual. Practices may include retention and detention basins, swales, ditches, storm sewer pipes and storm water inlets and post construction water quality practices.
(3) Inspection. The County Engineer and the Summit Soil and Water will have the work inspected to insure that the Developer has complied with the approved plans or necessary environmental conditions. Summit Soil and Water will provide site inspections to verify compliance with the SWPPP. Failure to comply with the plan may result in enforcement. The County Engineer may take necessary steps to provide corrective measures, and the cost of such services will be charged to the Developer. This does not relieve the Developer or contractor of any liability that may arise. No project will be released from Bond if there is failure to comply with an approved Comprehensive Stormwater Management Plan unless the Developer has performed cleanup and repair of damages. Final inspection requires all drainage facilities to be free of deposits from erosion, siltation and construction debris. The Preliminary Plan(s) for subsequent phases and proposed Final Plat(s) will be disapproved if there are compliance issues on any phase of a development. (Also refer to Inspection Requirements per Section 1110.07(c)).
