2. For critical wetland impacts, complete an alternatives analysis in accordance with subsection 9-11-2B of this title.
3. For impacts to regulatory wetland/waters of DuPage greater than 0.1 acre total surface area, or corps of engineers jurisdictional waters or wetland, complete an alternatives analysis in accordance with subsection 9-11-2C of this title.
B. USACE Jurisdictional Wetland: If a USACE jurisdictional wetland will be impacted, a copy of a letter of no objection, general, regional or individual permit shall be provided prior to issuance of the stormwater management certification, unless the director or administrator concludes otherwise. In which case, the certification can be conditioned to state that such work may not commence within or adjacent to the waters of the United States or wetland until receipt of the necessary USACE authorization.
C. Supporting Documentation: The following support documentation is required to be submitted. The administrator or director may waive the requirement to provide some or all of the following support documentation when considering the complexity and extent of the proposed development and its impact:

2. Statement indicating the date of the wetland boundary verification and OHWM verification.
3. Indirect impact determination. When required, documentation including: subarea watershed map and hydrologic calculations with a table summarizing results in accordance with the analysis in section 9-11-3 of this title is required.
4. Development narrative shall include the following applicable items:
a. Description of the functions of the impacted wetland or buffer, and how the impacts will be mitigated.
b. Historic aerials, if available, to document the previous site conditions or the extent of farmed wetland.
c. Description of mitigation method, location, and ratios.
d. Description of mitigation area and plan objectives.
e. Description of management practices. The document shall include clarification that prescribed burns and herbicide applications must be performed by trained/licensed personnel under the proper permits.
f. Performance standards.
g. Reporting requirements.
h. Hydrology monitoring methodology and goals.
i. Implementation schedule.
j. Native species list with quantities, size of stock, seeding rate and/or plug spacing.
k. Planting specifications and soil handling.
l. Cost estimate to include installation, management, monitoring, and reporting as anticipated to meet performance standards.
5. Plan view drawings and details, where applicable:
a. Existing and proposed topography.
b. Delineated wetland and waters of DuPage OHWM boundary to a submeter accuracy or better.
c. Buffer boundary.
d. Location of impacts to wetland and buffer.
e. A table shall be provided on the plans listing the total acreage of the existing wetland and buffer areas, and the proposed impact and mitigation areas. These calculated areas should also be graphically highlighted.
6. Wetland and buffer mitigation plan, if applicable, shall contain the following information:
a. Delineate and label planting and seeding zones.
b. Delineate and label mitigation and enhancement zones.
c. Existing and proposed topography.
d. Planting methodology and soil handling.
e. Proposed wetland and buffer boundaries.
f. Native species list including size of stock, quantity, seed rate, and spacing of plugs.
g. Woody planting locations, if any.
h. Signage or physical barrier locations.
i. Monitoring well locations, if installed.
j. Permanent transect locations and photo documentation points for monitoring, if required.
k. Maintenance and monitoring plan with performance standards. (Ord. G-976, 7-24-2012; Ord. G-1003, 6-11-2013)
