(d) Final Erosion Control Plan Contents. The following shall be the minimum requirements for items to be included in a final erosion and sediment
control plan:
1. Sites Less than One Acre of Total Land Disturbance.
A. A narrative describing the proposed land disturbing activity, construction timeline and sequencing, temporary BMPs to be used to minimize off-
site impacts during the construction phase, and proposed methods to stabilize the site following construction in accordance with the requirements
of this ordinance;
B. A survey map or scaled site plan drawing of sufficient clarity showing a north arrow, the location of proposed land disturbance, direction of flow
for runoff entering and leaving the disturbed area, upslope drainage area (if known), proposed BMPs, existing and proposed slopes, ground cover,
buildings, roads, access drives, property boundaries, drainage ways, water bodies, trees, culverts, utilities and other structures within 50 feet of the
proposed land disturbance;
C. The name, address and daytime phone number of the person(s) charged with installing and maintaining all best management practices;
D. For underground utility installations, the plans must delineate where utilities will be installed, show the location of the open cut and the
topography in the area, and list the total lineal feet to be installed and the lineal feet that will be done by open cut; and
E. Other information determined to be necessary by the DPW to ensure compliance with the requirements of this chapter.
2. Sites One Acre or Greater in Total Land Disturbance.
A. A site map in accordance with Sec. 19.11 (c) below;
B. A map at a scale of 1 inch equals no more than 100 feet (unless otherwise noted), delineating and labeling the following applicable items:
(i) North arrow, graphic scale, draft date, name and contact information for project engineer or planner and designation of source documents
for all map features.
(ii) 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;
(iii) Proposed building envelopes and other land area to be disturbed and size in acres;
(iv) All woodland areas, those proposed to be lost or transplanted during construction and acres or numbers of each. For woodlands proposed
to be lost, show individual trees larger than eight (8) inches in diameter that are located within twenty feet of proposed grading boundaries;
(v) Temporary access drive and specified surface material and minimum depth;
(vi) Temporary flow diversion devices for upslope or roof runoff until site is stabilized;
(vii) Temporary sediment trapping devices for site perimeter and inlets to culverts and storm drains;
(viii) Temporary settling basin or other BMP to be used for site dewatering during utility or other subsurface work;
(ix) Temporary soil stockpile sites indicating setbacks from nearby water resources or environmental corridors and the proposed erosion
protection methods;
(x) Detailed drawings and cross-sections for any sediment traps, basins or other major cut or fill areas requested by the DPW, showing side
slopes and elevations;
(xi) Final stabilization measures for open channels and erosion protection for pipe and channel inlets, outlets and emergency spillways;
(xii) 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;
(xiii) 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;
(xiv) 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;
(xv) Location of soil evaluations with surface elevations and unique references to supplemental soil evaluations report forms in accordance
with Sec. 19.12(e) below. Also show estimated highest ground 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.
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 sub. 19.11(e) below. 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.
(xvi) Spill prevention and response procedures.
(xvii) Other items specified by the DPW as necessary to ensure compliance with this ordinance.
C. Supporting information for the plan reviewer only:
(i) 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 sub. (b) above and the specific requirements under sub. (c) above;
Note: This information may be combined with a narrative for the stormwater management plan under Sec. 19.11(g) 12. The information may
also be useful to the grading contractor and could be included in the construction notes on the plan map under sub. B (xiv) above.
(ii) Summary of design data for any structural BMP such as sediment basins or sediment traps. 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;
(iii) Open channel design and stabilization data to support the selected BMPs for stabilization;
(iv) Soil evaluation reports, in accordance with the standards in Sec. 19.12(e), with unique references and elevations that match the map
under sub. B (xv) above.
(v) Estimated time soil stockpiles will exist to support the selected BMPs for erosion control;
(vi) Documentation that proposed utility locations and installation scheduling has been coordinated with the affected utility companies.
(vii) Documentation of any other calculations used to demonstrate compliance with the performance standards in this section.
