Property Location and Land Uses<br />

<strong>Manor</strong> <strong>Woods</strong> is located in incorporated <strong>Village</strong> <strong>of</strong> <strong>Glen</strong> <strong>Ellyn</strong>, DuPage County, IL<br />

(Exhibit 1). <strong>The</strong> property is bounded by residential property to the north, Brandon<br />

Avenue to the east, Illinois Street to the south, and Newton Avenue to the west. <strong>The</strong> legal<br />

description is SE ¼ S.15, T39N, R10E, 3 rd P.M. <strong>The</strong> property consists <strong>of</strong> approximately a<br />

14-acre woodland, which contains evidence <strong>of</strong> historic fill. This was based on<br />

observations <strong>of</strong> uneven land and the presence <strong>of</strong> utility lines. Furthermore, the installation<br />

<strong>of</strong> a stormwater utility running through the property may have lead to the draining <strong>of</strong> a<br />

larger historic wetland system.<br />

Purpose <strong>of</strong> the Field Investigation<br />

<strong>The</strong> purpose <strong>of</strong> the field investigation was to determine the existence, location, and size<br />

<strong>of</strong> any jurisdictional wetlands or Waters <strong>of</strong> the U.S. within the scope <strong>of</strong> the site. <strong>The</strong><br />

United States Army Corps <strong>of</strong> Engineers (Corps) outlined methods for delineating<br />

wetlands in the Corps <strong>of</strong> Engineers Wetlands Delineation Manual (Manual) dated 1987/<br />

Interim Regional Supplement to the Corps <strong>of</strong> Engineers Wetland Delineation Manual:<br />

Midwest Region dated September 2008. <strong>The</strong>se methods were used to delineate any<br />

jurisdictional areas. A floristic quality assessment was performed for each wetland by<br />

calculating the Coefficient <strong>of</strong> Conservatism (ĉ) and Floristic Quality Index (I) using plant<br />

species observed in the field and nomenclature given in Plants <strong>of</strong> the Chicago Region<br />

(Swink and Wilhelm 1994). In addition, a wildlife habitat and use assessment was<br />

determined using the Modified Michigan Department <strong>of</strong> Natural Resources Method<br />

(MDNR) and evaluation score sheet. Photographs have been provided in the appendices.<br />

Methodology<br />

<strong>The</strong> Corps Federal Register (1982) and Environmental Protection Agency (EPA) Federal<br />

Register (1980) jointly define wetlands as: “Those areas that are inundated or saturated<br />

by surface or ground water at a frequency and duration sufficient to support, and that<br />

under normal circumstances do support, a prevalence <strong>of</strong> vegetation typically adapted for<br />

life in saturated soil conditions.” <strong>The</strong>refore, in order to be considered a jurisdictional<br />

wetland, three criteria: soils, hydrology, and vegetation must be met.<br />

<strong>The</strong> Corps requires data forms and technical information as part <strong>of</strong> a delineation report to<br />

document the three criteria for any area determined to be a wetland. <strong>The</strong> corresponding<br />

data forms for this project are provided in Appendix A. A description <strong>of</strong> the three<br />

criteria, field methods, and floristic quality assessment are provided below.<br />

Hydrology:<br />

An area has wetland hydrology if it is inundated or saturated within the root zone and/or<br />

within 12” <strong>of</strong> the surface continuously for at least 5% <strong>of</strong> the growing season,<br />

approximately 9-14 days, in most years. <strong>The</strong> Manual defines the growing season as the<br />

portion <strong>of</strong> the year when the soil temperature (measured 20in below the surface) is above<br />

2


iological zero (5 o C or 41 o F) which can be approximated by the number <strong>of</strong> “frost free”<br />

days (>28 o F at a frequency <strong>of</strong> 5 years in 10).<br />

Recorded data such as: aerial photographs (Exhibit 4), stream gage data, planning<br />

documents, and federal, state, county, and local agency records were examined prior to<br />

the site investigation to determine if hydrology may be present. Primary and secondary<br />

indicators were investigated in the field. Inundation, saturation in the upper 12”, water<br />

marks, drift lines, sediment deposits, drainage patterns, oxidized root channels in the<br />

upper 12”, water-stained leaves, local soil survey data, and the FAC-neutral test are all<br />

examples <strong>of</strong> field indicators. Seasonal factors and pr<strong>of</strong>essional judgment were also taken<br />

into account when hydrology was determined.<br />

Soils:<br />

Hydric soils are those soils that are sufficiently wet in the upper part to develop anaerobic<br />

conditions during the growing season. <strong>The</strong> field indicators <strong>of</strong> hydric soils in LRR, K, L,<br />

M, N, O, P for Illinois were used to determine if hydric soild are present. Natural<br />

Resources Conservation Service (NRCS) soil maps were examined prior to the site<br />

investigation to determine if hydric soils were present (Exhibit 5). Mapped types and/or<br />

the presence <strong>of</strong> field indicators were confirmed by digging soil pits. Soil pits at all data<br />

points were dug to a depth <strong>of</strong> approximately 24”, if able, as field indicators are typically<br />

observed within 20-36 inches <strong>of</strong> the soil surface. Soil colors were determined using the<br />

Munsell Soils Color Charts, dated 2000.<br />

Vegetation:<br />

In order to be considered a wetland greater than 50% <strong>of</strong> the dominant plant species in the<br />

community must be hydrophytic. <strong>The</strong> USFWS published a regional list <strong>of</strong> plant species<br />

occurring in wetlands in 1988. Each species is assigned to a Wetland indicator category<br />

based upon its probability <strong>of</strong> naturally occurring in a wetland (Table 1). According to<br />

the Manual, when species that adapt for life in anaerobic soil conditions (OBL, FACW,<br />

FAC )immediately exceed 50% <strong>of</strong> the total dominance for each stratum, hydrophytic<br />

vegetation is present.<br />

<strong>The</strong> Chicago District <strong>of</strong> the Corps issued a Regional Permit Program (RRP) for activities<br />

with minimal impacts for Cook and the surrounding collar counties. <strong>The</strong> RRP authorizes<br />

structures or work in or affecting navigable waters <strong>of</strong> the U.S. under RHA Section 10 and<br />

CWA Section 404. Authorization under RHA Section 10 is required for construction <strong>of</strong><br />

structures such as piers, decks, breakwaters, jetties, utility lines, and activities such as<br />

dredging within, over, or under navigable waters <strong>of</strong> the United States. While,<br />

authorization for the discharge <strong>of</strong> dredged or fill material within CWA Section 404<br />

Waters <strong>of</strong> the U.S. is required.<br />

Activities are divided into two categories under the RRP (Category I & II). Projects that<br />

impact less than 0.10 acres <strong>of</strong> waters <strong>of</strong> the U.S. and do not impact any high-quality<br />

aquatic resources are processed under Category I. Compensatory mitigation is not<br />

required for impacts under 0.10 acres. Projects that impact over 0.10 acres and up to 2.0<br />

acres <strong>of</strong> waters <strong>of</strong> the U.S., or impact high-quality aquatic resources, are processed under<br />

Category II. Compensatory mitigation for impacts between 0.10 and 2.0 acres is<br />

required. High-Quality Aquatic Resources (HQARs) are generally considered unsuitable<br />

for dredge or fill activities. A description and list <strong>of</strong> HQARs as described by the Corps in<br />

the RRP is provided in Appendix F. Impacts to a high-quality aquatic resource or<br />

impacts over 2.0 acres require an Individual Permit (IP) as a more thorough examination<br />

<strong>of</strong> the project must be performed, in addition to public comment.<br />

A native upland buffer (or other appropriate vegetation approved by the Corps) adjacent<br />

to all created, restored, enhanced or preserved waters <strong>of</strong> the U.S. and wetlands must be<br />

established or enhanced. According to the RRP the following buffer widths are required:<br />

1) For a linear body <strong>of</strong> water (e.g., river, stream, creek, etc.), the buffer shall be a<br />

minimum <strong>of</strong> 50 feet from the Ordinary High Water Mark (OHWM) on both sides<br />

<strong>of</strong> the linear waterbody;<br />

2) For any waters <strong>of</strong> the U.S., including wetlands, over 0.10 acres and up to 0.5 acres<br />

in size, the buffer shall be 30 feet wide;<br />

3) For any waters <strong>of</strong> the U.S. including wetlands, 0.5 acres or larger in size, the<br />

buffer shall be 50 feet wide; and<br />

4) For any area determined to be a high-quality resource, the buffer shall be 100 feet<br />

wide;<br />

<strong>The</strong> above requirements do not apply to linear road crossings.<br />

DuPage County:<br />

Per Article 10 Section 15-147 <strong>of</strong> the January 2004 DuPage County Countywide<br />

Stormwater and Flood Plain Ordinance (DCSFPO), a stormwater permit is required if<br />

the development involves one or more special management areas. Special management<br />

areas include regulatory floodplains, wetlands, riparian areas, and wetland buffers. Both<br />

isolated and adjacent wetlands are jurisdictional under the (DCSFPO). All wetland<br />

determinations and delineations that are conducted in DuPage County are required to use<br />

procedures in accordance with the current Federal wetland delineation methodology<br />

authorized under Section 404 <strong>of</strong> the CWA. As such, the above methodology as set forth<br />

in the Manual was used. All wetland delineations must be verified by DuPage County or<br />

the authorized Ordinance Administrator for all complete waiver communities. <strong>The</strong> Corps<br />

has issued DuPage County Department <strong>of</strong> Development and Economic Planning a<br />

5


Programmatic General Permit (RP-25), which designates the County as the lead agency<br />

to review permits involving wetlands.<br />

Per Section 15-134.3 <strong>of</strong> the DCSFPO all wetlands must be classified as critical or<br />

regulatory based on the assessment <strong>of</strong> certain functions and values. <strong>The</strong>y are as follows:<br />

• <strong>The</strong> wetland is identified as a critical wetland in the County's wetland inventory.<br />

• <strong>The</strong> wetland is known to possess a Federal or State listed threatened or<br />

endangered species based on the consultation with the Illinois Department <strong>of</strong><br />

Natural Resources.<br />

• <strong>The</strong> plant community within the wetland is determined to have a native floristic<br />

quality index <strong>of</strong> 20 or higher during a single season assessment, a native mean C-<br />

value <strong>of</strong> 3.5 or greater, or alternatively a natural area rating index (NARI) value <strong>of</strong><br />

35.0 or higher during a spring, summer, and fall assessment, as calculated by the<br />

Swink & Wilhelm methodology. If both methods are performed, the NARI value<br />

shall prevail as the determining value.<br />

• <strong>The</strong> initial wildlife quality value using the Modified Michigan Department <strong>of</strong><br />

Natural Resources Method is 5.0 or higher, or alternatively the mean rated<br />

wildlife quality (MWRQ) is determined to be 8.0 or higher, as calculated by the<br />

Ludwig wildlife habitat evaluation methodology. If both methods are performed,<br />

the Ludwig value shall prevail as the determining value.<br />

Development within or affecting critical wetlands under the DCFSPO is prohibited,<br />

unless documentation is submitted that conclusively proves that the presence <strong>of</strong> critical<br />

wetlands precludes all economic use <strong>of</strong> the entire parcel, and that no practicable<br />

alternative to wetland modification exists. Mitigation for impacts to critical wetlands is<br />

required at a minimum proportional rate <strong>of</strong> three to one (3:1).<br />

All other wetlands that do not meet any <strong>of</strong> the functions and values described above are<br />

considered regulatory. Development within or affecting a regulatory wetland that is<br />

equal to or greater than 0.10 acre shall be prohibited unless documentation is submitted<br />

that conclusively proves that no practicable alternative to wetland modification exists.<br />

While, development within or affecting a regulatory wetland that includes contiguous<br />

waters <strong>of</strong> DuPage less than 0.10 acre does not require documentation showing that no<br />

practicable alternatives to wetland modification exists. Waters <strong>of</strong> DuPage are defined as:<br />

all waters such as lakes, rivers, streams (including intermittent streams), mudflats,<br />

wetlands, sloughs, wet meadows, or natural ponds, all impoundments <strong>of</strong> waters not<br />

otherwise defined as waters <strong>of</strong> DuPage under the definition, tributaries <strong>of</strong> waters<br />

identified above, and wetlands adjacent to waters identified above. Mitigation for<br />

impacts to regulatory wetlands is required at a minimum proportional rate <strong>of</strong> one and a<br />

half to one (1.5:1).<br />

Per Section 15-135.14, to the extent practicable, development within 50ft <strong>of</strong> a regulatory<br />

wetland and 100ft <strong>of</strong> a critical wetland shall not, without mitigation: adversely change the<br />

quantity, quality, or temporal and aerial distribution <strong>of</strong> flows entering any adjacent<br />

wetlands or waters; nor destroy or damage vegetation that stabilizes wetland fringe areas<br />

or provides overland flow filtration to wetlands; nor adversely affect any ground water<br />

infiltration functions.<br />

Jurisdictional Wetlands and Waters <strong>of</strong> the U.S.<br />

<strong>The</strong>re are three wetland/ draingeway areas and three Waters <strong>of</strong> the U.S. located within the<br />

scope <strong>of</strong> the project. <strong>The</strong> boundaries <strong>of</strong> the wetlands were staked with pink pin flags with<br />

the wording “Wetland Delineation.” Data points were taken both within and outside <strong>of</strong><br />

the wetland boundaries to support our conclusions. <strong>The</strong>se data points are marked on an<br />

aerial photograph with the approximate wetland boundary (Exhibit 8). <strong>The</strong><br />

corresponding data forms are provided in Appendix A. <strong>The</strong> following text characterizes<br />

the each wetland.<br />

Wetland/ Drainageway 1:<br />

This system is a wetland swale formed by drainage from a storm sewer outlet which runs<br />

underneath Brandon Road. Both the U.S. Fish and Wildlife Service (USFWS) National<br />

Wetland Inventory (NWI) Map (Exhibit 3) and the DuPage County Wetland Inventory<br />

Maps (Exhibit 2) identity wetlands within the project location. One wetland and one<br />

upland data point were taken in and adjacent to the wetland.<br />

Hydrology is provided by the stormwater culvert, precipitation, surface run<strong>of</strong>f, and<br />

possibly groundwater. Surface water, saturation in the upper twelve inches and drainage<br />

patterns were the indicators used to determine persistent hydrology. Soils are mapped as<br />

903A - Muskego and Houghton Mucks, a hydric, as identified by the Soil Survey <strong>of</strong><br />

DuPage County, IL, dated 1997. <strong>The</strong> hydric qualities associated with these soils were<br />

verified, via test indicators A12- Thick Dark Surface and F2- Loamy Gleyed Matrix.<br />

Dominant vegetation consisted <strong>of</strong> Box Elder (Acer negundo), Garlic Mustard (Alliaria<br />

petiolata) and Honewort (Cryptotaenia Canadensis). As such, this wetland area satisfies<br />

all three criteria and qualifies as a wetland.<br />

<strong>The</strong> Coefficient <strong>of</strong> Conservatism (C), Floristic Quality Index (I), and Mean Wetness<br />

Coefficient for the wetland were 1.0, 1.73, and -1.7, respectively. <strong>The</strong>refore, this wetland<br />

is not indicative <strong>of</strong> a High Quality Aquatic Resource (Appendix F). <strong>The</strong> floristic quality<br />

assessment is provided in Appendix B.<br />

<strong>The</strong> MDNR Wildlife Habitat/Use Evaluation Score Sheet was used to evaluate the<br />

wildlife quality <strong>of</strong> the area. <strong>The</strong> total score was determined to be 2.5; the evaluation<br />

score sheet is provided in Appendix C. As such, the wetland does not receive a critical<br />

status, rather, it receives a regulatory status. <strong>The</strong> Illinois Department <strong>of</strong> Natural<br />

Resources (IDNR) was consulted regarding the existence <strong>of</strong> threatened and endangered<br />

species on the property. After receiving their response, it was concluded that no<br />

threatened and endangered species inhabit the area and therefore the consultation was<br />

terminated. <strong>The</strong>ir findings have been included in Appendix E.<br />

This wetland provides limited functions due to its small size and location. Several<br />

functions include: sediment and nutrient assimilation from upland areas thus reducing the<br />

impact <strong>of</strong> urbanization on water quality by filtering and assimilating nutrients discharged<br />

from surrounding uplands, and forage, shelter and perching habitat for local wildlife.<br />

7


As this wetland is considered to be regulatory, a 50ft buffer is present. <strong>The</strong> buffer<br />

currently provides limited functions due to the surrounding land use. <strong>The</strong> existing buffer<br />

surrounding the wetland is consists <strong>of</strong> scrub shrub and overstory trees, which provides<br />

some soil stabilization, ground water infiltration, and pollutant assimilation functions.<br />

Wetland 2:<br />

This system is a drainage sheet flow area formed by drainage from a storm sewer outlet.<br />

Both the U.S. Fish and Wildlife Service (USFWS) National Wetland Inventory (NWI)<br />

Map (Exhibit 3) and the DuPage County Wetland Inventory Maps (Exhibit 2) identity<br />

wetlands at this location. One wetland and one upland data point were taken in and<br />

adjacent to the wetland.<br />

Hydrology is provided by the stormwater culvert, direct precipitation, and surface run<strong>of</strong>f.<br />

Saturation in the upper twelve inches, water stained leaves and drainage patterns were the<br />

indicators used to determine persistent hydrology. Soils are mapped as 223C2 - Varna<br />

Silt Loam and 903A - Muskego and Houghton Mucks at this location. Both are hydric or<br />

have hydric inclusions <strong>of</strong> hydric soils as identified by the Soil Survey <strong>of</strong> DuPage County,<br />

IL, dated 1997. <strong>The</strong> hydric qualities associated with these soils were verified via test<br />

indicators A12- Thick Dark Surface and F2- Loamy Gleyed Matrix. Dominant vegetation<br />

consisted <strong>of</strong> Garlic Mustard (Alliaria petiolata), Pokeweed (Phytolacca americana), and<br />

Reed Canary Grass (Phalaris arundinacea). As such, this wetland area satisfies all three<br />

criteria and qualifies as a wetland.<br />

<strong>The</strong> Coefficient <strong>of</strong> Conservatism (C), Floristic Quality Index (I), and Mean Wetness<br />

Coefficient for the wetland were 0.67, 1.15, and -1.0, respectively. <strong>The</strong>refore, this<br />

wetland is not indicative <strong>of</strong> a High Quality Aquatic Resource (Appendix F). <strong>The</strong><br />

floristic quality assessment is provided in Appendix B.<br />

<strong>The</strong> MDNR Wildlife Habitat/Use Evaluation Score Sheet was used to evaluate the<br />

wildlife quality <strong>of</strong> the area. <strong>The</strong> total score was determined to be 2.0; the evaluation<br />

score sheet is provided in Appendix C. As such, the wetland does not receive a critical<br />

status, rather, it receives a regulatory status. <strong>The</strong> Illinois Department <strong>of</strong> Natural<br />

Resources (IDNR) was consulted regarding the existence <strong>of</strong> threatened and endangered<br />

species on the property. After receiving their response, it was concluded that no<br />

threatened and endangered species inhabit the area and therefore the consultation was<br />

Wetland 3:<br />

This system is a wetland swale formed by drainage from a storm sewer outlet. Both the<br />

U.S. Fish and Wildlife Service (USFWS) National Wetland Inventory (NWI) Map<br />

(Exhibit 3) and the DuPage County Wetland Inventory Maps (Exhibit 2) identity<br />

wetlands within the project location. One wetland and one upland data point was taken in<br />

dated 1997. <strong>The</strong> hydric qualities associated with these soils were verified via test<br />

indicators F6- Redox Dark Surface. Dominant vegetation consisted <strong>of</strong> Garlic Mustard<br />

(Alliaria petiolata), Common Buckthorn (Rhamnus cathartica), Elderberry (Sambucus<br />

canadensis), and Reed Canary Grass (Phalaris arundinacea). As such, this wetland area<br />

satisfies all three criteria and qualifies as a wetland.<br />

<strong>The</strong> Coefficient <strong>of</strong> Conservatism (C), Floristic Quality Index (I), and Mean Wetness<br />

Coefficient for the wetland were 1.67, 2.89, and -2.0, respectively. <strong>The</strong>refore, this<br />

Waters <strong>of</strong> the U.S 1:<br />

This area is located at the northwest corner <strong>of</strong> the site and contains a braided channel<br />

formed by a storm sewer outlet. <strong>The</strong> vegetation in this area is limited and hydrology is<br />

provided by <strong>of</strong>f-site drainage from surrounding impervious areas.<br />

Waters <strong>of</strong> the U.S 2:<br />

This area is located at the northeast corner <strong>of</strong> the site and contains a channel formed by a<br />

storm sewer outlet. <strong>The</strong> vegetation in this area is limited and hydrology is provided by<br />

<strong>of</strong>f-site drainage from surrounding impervious areas.<br />

Waters <strong>of</strong> the U.S 3:<br />

This area is located at the southwest corner <strong>of</strong> the site and contains a channel formed by a<br />

storm sewer outlet. <strong>The</strong> vegetation in this area is limited and hydrology is provided by<br />

<strong>of</strong>f-site drainage from surrounding impervious areas.<br />

Conclusions and Recommendations<br />

Regarding future permit submittals for construction on the lots in question, the DCSFPO<br />

requires the following additional information with regard to wetlands:<br />

1. <strong>The</strong> wetland boundaries should be surveyed under the direction <strong>of</strong> an Illinois<br />

Registered Land Surveyor and the surveyed delineation line should be transposed<br />

onto the site topographic survey. <strong>The</strong> wetland buffer should also be shown on the<br />

survey.<br />

2. <strong>The</strong> wetlands appear to be isolated and are therefore unlikely to be Corps<br />

jurisdictional. A Jurisdictional Determination (JD) from the Army Corps <strong>of</strong><br />

Engineers should be applied for to verify if the wetlands/Waters are Corps<br />

jurisdictional. All wetlands regardless <strong>of</strong> size and function are considered<br />

jurisdictional under the DCSFPO.<br />

3. Wetland Buffers must be identified (50’ from the wetland edge) and mitigation<br />

provided for any loss <strong>of</strong> buffer functions (vegetation, habitat, water quality) due to<br />

development.<br />

4. An avoidance and minimization argument must be made if impacts to the wetland<br />

are proposed.<br />

5. If impacts to the wetland are proposed mitigation must be provided on-site or<br />

through wetland banking.<br />

10


6. In addition to the submittal <strong>of</strong> a Stormwater Management Permit Application, a<br />

Joint Permit Application must be made to the appropriate Federal and State<br />

agencies.<br />

7. <strong>The</strong> <strong>Village</strong> <strong>of</strong> <strong>Glen</strong> <strong>Ellyn</strong> Planning Department should be notified in writing<br />

prior to the commencement <strong>of</strong> any vegetation removal.<br />

8. A formal Vegetative Maintenance Plan should be submitted to the <strong>Village</strong> <strong>of</strong> <strong>Glen</strong><br />

<strong>Ellyn</strong> Planning Department prior to the commencement <strong>of</strong> any vegetation<br />

removal.<br />

APPENDIX F<br />

HIGH-QUALITY AQUATIC RESOURCES<br />

U.S. Army Corps <strong>of</strong> Engineers, Chicago District Regional Permit Program<br />

High-quality aquatic resources (HQARs) are aquatic areas considered to be regionally critical due to their<br />

uniqueness, scarcity, and/or value, and other wetlands considered to perform functions important to the<br />

public interest, as defined in 33 CFR Part 320.4(b)(2). <strong>The</strong>se resources include Advanced Identification<br />

(ADID) sites, bogs, ephemeral pools, fens, forested wetlands, sedge meadows, seeps, streams rated Class A<br />

or B in the Illinois Biological Stream Characterization study, streamside marshes, wet prairies, wetlands<br />

supporting Federal or Illinois endangered or threatened species, and wetlands with a floristic quality index<br />

<strong>of</strong> 20 or greater or mean C-value <strong>of</strong> 3.5 or greater. <strong>The</strong> following descriptions <strong>of</strong> high-quality aquatic<br />

resources apply to the Chicago District only.<br />

Advanced Identification (ADID) sites: Aquatic sites that have been identified by the District and U.S.<br />

Environmental Protection Agency, in advance <strong>of</strong> specific permit requests, as areas generally unsuitable for<br />

disposal <strong>of</strong> dredged or fill material. ADID sites include various waters <strong>of</strong> the U.S., including wetlands,<br />

identified in Lake and McHenry Counties.<br />

Bog: A low nutrient peatland, usually in a glacial depression, that is acidic in the surface stratum and <strong>of</strong>ten<br />

dominated at least in part by the genus Sphagnum.<br />

Ephemeral pool: A seasonally inundated depression within a forested wetland or upland community,<br />

usually located on a moraine, glacial outwash plain, or in an area shallow to bedrock; also known locally as<br />

a “vernal pool.” <strong>The</strong>se areas may not be permanently vegetated.<br />

Fen: A peatland, herbaceous (including calcareous floating mats) or wooded, with calcareous groundwater<br />

flow.<br />

Forested wetland: A wetland dominated by native woody vegetation with at least one <strong>of</strong> the following<br />

species or genera present: Carya spp., Cephalanthus occidentalis, Cornus alternifolia, Fraxinus nigra,<br />

Juglans cinerea, Nyssa sylvatica, Quercus spp.,or Thuja occidentalis.<br />

Sedge meadow: A wetland dominated by at least one <strong>of</strong> the following genera: Carex, Calamagrostis,<br />

Cladium, Deschampsia, Eleocharis, Rhynchospora, Scleria, or Eriophorum.<br />

Seep: A wetland, herbaceous or wooded, with saturated soil or inundation resulting from the diffuse flow<br />

<strong>of</strong> groundwater to the surface stratum.<br />

Streams rated A or B in the Illinois Biological Stream Characterization study:<br />

Reference Illinois Environmental Protection Agency’s Biological Stream<br />

Characterization (BSC): Biological Assessment <strong>of</strong> Illinois Stream Quality (latest edition) for a current<br />

listing.<br />

Streamside marsh: A wetland that is adjacent to, and contiguous with, a body <strong>of</strong> flowing water or<br />

supported by stream baseflow and dominated by herbaceous species.<br />

Wet prairie: A wetland dominated by native graminoid species with a diverse indigenous forb component<br />

that is seasonally saturated and/or temporarily inundated.<br />

Wetlands supporting Federal or Illinois endangered or threatened species: For<br />

current state-listed species, reference Illinois Endangered Species Protection Board’s “Checklist <strong>of</strong><br />

Endangered and Threatened Animals and Plants <strong>of</strong> Illinois” and/or contact the Illinois Department <strong>of</strong><br />

Natural Resources. For Federally-listed species, reference the U.S. Fish and Wildlife Service’s<br />

“Endangered and Threatened Wildlife and Plants” list (latest edition) and/or contact the U.S. Fish and<br />

Wildlife Service.<br />

Wetlands with a Floristic Quality Index <strong>of</strong> 20 or greater or a mean C-value <strong>of</strong> 3.5 or<br />

greater: Reference Plants <strong>of</strong> the Chicago Region (F. Swink and G. Wilhelm, 4 th edition, Indianapolis:<br />

Indiana Academy <strong>of</strong> Science, 1994).<br />

Further information on the areas described above can be found in the U.S. Environmental Protection<br />

Agency’s Advanced Identification studies for Lake and McHenry Counties, the Chicago Wilderness’<br />

Biodiversity Recovery Plan, the Forest Preserve District <strong>of</strong> Cook County’s <strong>The</strong> Natural Communities <strong>of</strong><br />
