This section is included in your selections.

(a) The following shall be the minimum requirements for items to be included in a final erosion control plan:

1. A site map in accordance with Section 17.09-5;

2. North arrow, graphic scale, draft date, name and contact information for project engineer or planner and designation of source documents for all map features.

3. Proposed site topography at contour intervals not to exceed two feet, proposed percent slope for all open channels and side slopes and all proposed runoff discharge points from the site;

4. Proposed building envelopes and other land area to be disturbed and size in acres;

5. Temporary access drive and detail consistent with WDNR Technical Standard 1057.

6. Temporary flow diversion devices for upslope or roof runoff until site is stabilized and detail consistent with WDNR Technical Standard 1066;

7. Temporary sediment trapping devices for site perimeter and inlets to culverts and storm drains consistent with WDNR Technical Standard 1063;

8. Temporary settling basin or other BMP to be used for site dewatering during utility or other subsurface work consistent with WDNR Technical Standard 1061;

9. Temporary soil stockpile sites indicating setbacks from channelized flow, nearby water resources or environmental corridors and the proposed erosion protection methods;

10. Detailed drawings and cross-sections for any sediment traps, basins or other major cut/fill area, showing side slopes and elevations;

11. Final stabilization measures for open channels and erosion protection for pipe and channel inlets, outlets and emergency spillways;

12. Location of proposed utilities, including: standard cross-section for buried utilities, associated easements, labeling the type of utility and notes on erosion control and restoration plans;

13. Final site stabilization instructions for all other disturbed areas, showing areas to be stabilized in acres, depth of applied topsoil, seed types, rates and methodology, fertilizer, sod or erosion matting specifications, maintenance requirements until plants are well established, and other BMPs used to stabilize the site;

14. Detailed construction notes clearly explaining all necessary procedures to be followed to properly implement the plan, including estimated starting date of grading, timing and sequence of construction or demolition, any construction stages or phases, utility installation, dewatering plans, refuse disposal, inspection requirements, and the installation, use, and maintenance of best management practices proposed in the plan;

15. Location of soil evaluations with surface elevations and unique references to supplemental soil evaluations report forms in accordance with Section 17.16-5. Also show estimated seasonal water table depths and soil textures down to planned excavation depths, which may be on a separate map with sufficient references to the proposed site plan.

16. Spill prevention and response procedures.

Note: Water table depths are needed to plan for dewatering activities for excavations and utility installations and to document compliance with water table separation requirements under Section 17.09-3(f)7. The separate map may be at a different scale if needed. Soil textures help the project engineer and grading contractor plan for excavation, soil stockpiles, earthen berm compaction, pond lining, dust control, site stabilization and other grading related activities.

17. Other items specified by P&D as necessary to ensure compliance with this ordinance.

(b) Erosion Control Plan Supporting Information:

1. A narrative summary of the erosion control plan, briefly explaining the overall plan and, any unique information that led to the selection of BMPs and how the plan meets the guiding principles under Section 17.15-2 and the specific requirements under Section 17.15-3;

2. Summary of design data for any structural BMP such as sediment basins or sediment traps. Sediment basins shall be sized to hold the 100-yr design storm in the stripped non-vegetated construction condition. A professional engineer, licensed in the State of Wisconsin, shall stamp and sign a statement approving all designs and certifying that they have read the requirements of this ordinance and that, to the best of their knowledge, the submitted plans comply with the requirements;

3. Hydraulic and hydrologic data summaries for interim site conditions in the stripped, non-vegetated conditions. Any stormwater

4. Open channel design and stabilization data to support the selected BMPs for stabilization;

5. Soil profile evaluation reports, in accordance with the standards in Section 17.16-5, with unique references and elevations that match the map under Section 17.15-5(a)1.

6. Estimated time soil stockpiles will exist to support the selected BMPs for erosion control;

7. Documentation that proposed utility locations and installation scheduling has been coordinated with the affected utility companies.

8. Documentation of any other calculations used to demonstrate compliance with the performance standards in this section.

9. Identification of the primary contacts for:

1. Conducting erosion control inspections and how they will make the inspections available to P&D.

2. Completing site grading and temporary erosion control practices.

3. Completing final site restoration and stabilization.

Note: An Erosion Control Plan Requirements Checklist shall accompany all final erosion control plan submittals. The checklist can be obtained on the Kenosha County website or by contacting P&D. [Code § 17.15-5.]
