ABSTRACT

This document reports on the results of a wetland investigation required for replacement of an existing bridge on S.R. 4021, Section 39M over the North Branch of Indian Run, in Wallace Township, Chester County, Pennsylvania. Within the project area, S.R. 4021 is a two-lane rural road through a residential and agricultural district. The existing culvert and timber bridge shows signs of spalling and erosion, and does not meet current design standards. The proposed project would replace the existing culvert and timber beam bridge over the waterway. Current land use within the project area includes residential and forested areas. Wetland determinations were made in accordance with the U.S. Army Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987). The North Branch of Indian Run flows from northwest to southeast through the project study area, and discharges into Indian Run outside of the project limits. Indian Run is a tributary of the East Branch of Brandywine Creek, and part of the Brandywine-Christina Watershed in the Delaware River Basin. The entire basin of Indian Run, including the North Branch of Indian Run, is listed as a High Quality–Cold Water Fishery (HQ-CWF) according to PA Code Chapter 93. The project study area begins at the intersection of S.R. 4021 (Springton Road) and S.R. 4023 (Indiantown Road) to approximately 16.8 meters (55.0 ft) west of the bridge on S.R. 4021. The width of the project study area is 25.9 meters (85.0 ft) north and 16.8 meters (55.0 ft) south of S.R 4021. Two palustrine wetlands were identified within the project study area. A total of 142.24 square meters (1531.07 sq ft) of palustrine emergent wetlands were delineated; 26.67 square meters (287.07 sq ft) of these wetlands are within the project limits. The two wetlands are both located adjacent to the North Branch of Indian Run. An initial field reconnaissance was conducted on May 3, 2002. The wetlands within the study area were delineated in December 2002. Photographs of the wetland areas and vicinity are included in Appendix A. Observations of the wetland parameters were documented on Routine Data Forms and are attached as Appendix B. Appendix C contains a summary of the individual soil series that may be found underlying the waterway and wetland areas. The wetland study limits, data collection points, wetland boundaries, and photograph locations and directions are indicated on Plan Sheet 1 in Appendix D.

1. Introduction

I. INTRODUCTION

A. Project Location and Description

This document reports on the results of a wetland investigation required for the replacement of

an existing culvert and timber bridge on S.R. 4021, Section 39M over the North Branch of Indian

Run, in Wallace Township, Chester County, Pennsylvania (Figure 1). The project study area

begins at the intersection of S.R. 4021 (Springton Road) and S.R. 4023 (Indiantown Road) to

approximately 16.8 meters (55.0 ft) west of the bridge on S.R. 4021. The width of the project

study area is 25.9 meters (85.0 ft) north and 16.8 meters (55.0 ft) south of S.R 4021.

Proposed improvements to S.R. 4021 include the replacement of the existing bridge along the

same alignment, and slight widening of the roadway approaches to the bridge.

B. Description of the Project Study Area

The study area primarily consists of residential and agricultural land within Wallace Township,

Chester County. The North Branch of Indian Run flows northwest to southeast through the

project area. As a tributary to Indian Run, the waterway is classified as a High Quality-Cold

Water Fishery (HQ-CWF) under Pennsylvania Code 25: Chapter 93. The waterway width varies

throughout the project area from 2.7 to 6.1 meters (9.0 to 20.0 ft). The North Branch of Indian

Run discharges into Indian Run downstream of the S.R. 4021 bridge, outside of the project study

area.

The National Wetland Inventory (NWI) Quadrangle of Wagontown, Pennsylvania indicates that

no wetlands were mapped within the project area (Figure 2). Two palustrine forested (PFO)

wetlands are located along Indian Run and North Branch of Indian Run, outside of the project

area. Field observations, completed on December 31, 2002, indicate that two palustrine emergent

(PEM) wetlands, one upstream and one downstream of S.R. 4021, are located adjacent to the

North Branch of Indian Run within the project study area.

II. APPROACH TO THE INVESTIGATION

This report was prepared to satisfy the requirements of the U.S. Army Corps of Engineers

(ACOE), which has jurisdictional authority over “Waters of the United States” which include

waterways and wetlands, under the purview of Section 404 of the Clean Water Act. This report

also meets the requirements of the PADEP under Chapter 105, The Dam Safety and

Encroachment Act. Water quality and special status for “Waters of the United States” identified

in the project area were described according to the PADEP, Title 25, Chapter 93.

An initial desk review involved the examination of existing literature and mapping, including the

U.S. Geological Survey 7.5-minute topographic quadrangle for Wagontown, Pennsylvania

(Figure 1), U.S. Fish and Wildlife Service (USFWS) NWI mapping for the Wagontown,

Pennsylvania quadrangle (Figure 2), and the 1963 USDA Soils Survey of Chester and Delaware

Counties, Pennsylvania (Figure 3). These sources were reviewed to determine potential wetland

areas as well as previously identified wetlands within the project study area.

The wetland investigation was conducted in accordance with the procedures outlined in the U.S.

Army Corps of Engineers Wetlands Delineation Manual (Environmental Laboratory 1987). An

initial field reconnaissance was conducted on May 3, 2002. Field data was collected on

December 31, 2002. Photographs were taken during the initial field reconnaissance in May 2002

and during wetland delineation in December 2002.

ACOE regulations require that the following three criteria be met for an area to be classified as a

jurisdictional wetland: the dominance of hydrophytic vegetation, the presence of hydric soils,

and the evidence of wetland hydrology (Environmental Laboratory 1987). The Routine On-Site

Determination Plant Community Assessment Procedure was followed. This approach requires

the identification of representative plant community types in the area of study, and the

characterization of vegetation, soils, and hydrology for each plant community type. Wetland

boundaries are delineated after identifying wetland and non-wetland plant communities, and after

observing the three mandatory criteria for soils, vegetation, and hydrology.

Observations were made as necessary to ensure adequate coverage and characterization of the

project area. Observations were recorded on field data sheets at representative points located in

both upland and wetland areas (Appendix B). The entire project area was evaluated, with special

attention given to topographically low areas, areas adjacent to streams, hydric soils, and areas

with poorly drained soils.

After wetland boundaries were flagged and numbered, they were surveyed by Erdman, Anthony,

Associates, Inc.

A. Soils

Soils located within the study area were identified using the Soils Survey of Chester and

Delaware Counties, Pennsylvania (USDA 1963; Figure 3). Soil types in and around the

waterway are predominantly Glenville silt loam (GnA, GnB) with Wehadkee silt loam (We)

along the North Branch of Indian Run and Glenelg channery silt loam (GeD3) to the west of the

bridge.

Wehadkee silt loam (We) is listed as a Hydric Soil of Chester County and of the United States.

Glenville silt loam, 0-3 percent slopes (GnA) and 3-8 percent slopes (GnB), are soils with hydric

inclusions in Chester County, and are also listed as Prime Farmland Soil for Chester County.

Land within the project area is forested and residential; there is no active farmland within the

project study area. Representative descriptions of these soil series are included in Appendix C.

Soil test pits were excavated in the study area to determine if hydric soil characteristics were

present. The soil test pit locations are represented as U-1, U-2, etc., in the upland and as W-1, W-

2, etc., in the wetland. The soil test pits were dug to a minimum depth of 45.7 centimeters (18.0

in) when possible; however, several instances of refusal occurred at less than 45.7 centimeters

(18.0 in) due to soil compaction or rock. The colors of the soil matrix and mottles were described

using the Munsell Soil Color Charts (Macbeth Division of Kollmorgen Instruments Corporation

1992). Data sheets describing the soil within the project area can be found in Appendix B.


B. Vegetation

Representative observation points were selected within each plant community of the project

study area, and field data sheets were completed for each of these sample points. Visual

estimates of species abundance were made at each sample point, and the dominant species were

determined and recorded by genus and species on the field data sheets contained in Appendix B.

Dominant species were determined separately for each vegetative stratum as herbs,

sapling/shrub, trees, and vine.

Species indicator status was determined according to the National List of Plant Species That

Occur in Wetlands: Region 1, Northeast (Sabine 1993). Hydrophytic vegetation is defined as a

plant community with greater than 50 percent of the dominant plant species ranked as obligate

wetland (OBL), facultative wetland (FACW), or facultative (FAC or FAC+). Non-hydrophytic

vegetation is defined as a plant community with greater than 50 percent of the dominant plant

species ranked as facultative (FAC-), facultative upland (FACU), or upland (UPL). If a plant is

not included on the national list, it is noted as not listed (NL) and assigned an indicator value

based on its characteristics and the habitat in which it was located. Species of uncertain indicator

value are ranked as either no agreement (NA) or as no indicator assigned (NI). Positive (+) or

negative (-) modifiers indicate a greater or lesser occurrence in either wetland or upland

conditions from the major ranking classification.

C. Hydrology

Site hydrology was determined in the field on December 31, 2002, based on properties such as

soil saturation, inundation, oxidized root zones, manganese concretions, drainage patterns, and

proximity to a perennial waterway. Hydrologic indicators are based on the U.S. Army Corps of

Engineers Wetlands Delineation Manual (Environmental Laboratory 1987).

3. Investigation Results

III. INVESTIGATION RESULTS

As a result of the field investigation, 142.24 square meters (1531.07 sq ft) of PEM wetland were

delineated; 26.67 square meters (287.07 sq ft) of this wetland area are within the project limits.

Although all wetlands delineated in the project area are hydrologically connected due to the

proximity of the North Branch of Indian Run, the vegetative community differs between Wetland

1 and Wetland 2. Wetland vegetation and characteristics typical of the delineated wetland in the

study area are depicted in the photographs in Appendix A. All wetland areas are depicted on Plan

Sheet 1 (Appendix D).

The wetland community identified during the field investigation is described separately from the

upland community in the following section. For each plant community identified, a description

of the following information is given: vegetative composition, soil series as indicated by the soil

survey, soil characteristics as determined in the field, and general indications of the presence or

absence of wetland hydrology. Table 1 is a summary of the wetlands located within the project

area.

Table 1. Wetland Area Within the Project Limits.

Wetland # Type Square Meters (sq ft)

1 PEM 7.09 (76.28)

2 PEM 19.58 (210.79)

A. Waterways

The project will replace the existing culvert carrying S.R. 4021 over the North Branch of Indian

Run. The entire Indian Run watershed is designated as a High Quality–Cold Water Fishery by

Pennsylvania Code Title 25, Environmental Protection, Chapter 93, Water Quality Standards.

Indian Run is a tributary of the East Branch of the Brandywine Creek. Tributaries to Indian Run

are included on the Pennsylvania Fish and Boat Commission’s (PFBC's) Listing of Surveyed

Streams Having Verified Trout Reproduction (PFBC 2001).

The waterway likely supports both submerged aquatic and emergent wetland vegetation along

the primary banks during the growing season. The waterway was defined as a “Waters of the


United States” due to the perennial streamflow, the presence of a streambed, and the average

depth of water in the channel. Average depth of the waterway ranges from less than 0.2 meters to

0.6 meters (0.5 to 2.0 ft) in depth.

The banks are natural but show signs of alteration upstream of the bridge. The upstream western

banks have been altered for construction of a residential driveway and ornamental cultivation.

The upstream eastern banks of the waterway have a rock-lined ditch running parallel to S.R.

4021 for storm-water drainage and discharge.

B. Wetlands

Two PEM wetlands were identified within the project area; both wetlands are located adjacent to

the North Branch of Indian Run. Table 2 lists all species of vegetation identified within the

project area, as well as the wetland indicator status for each species. Table 3 lists only the species

of hydrophytic dominant vegetation (FAC or wetter) identified within the project area and their

indicator status.

1. Wetland 1. The wetland area is located entirely within the secondary banks of the

North Branch of Indian Run, below the ordinary high-water line. Wetland 1 is completely

located within the project study area.

Wetland 1 consists of 7.09 square meters (76.28 sq ft) of wetland area. The wetland is classified

as a PEM community according to Cowardin (Cowardin et al. 1979). Due to frequent flooding

and seasonal differences in vegetation appearance and persistence, observed diversity of the area

was low in December of 2002.

Symplocarpus foetidus skunk cabbage OBL 5/3/02


Dominant species in this community include a mix of facultative wetland, facultative, and

facultative upland species. Phalaris arundinacea (reed canary grass, FACW+) was a dominant

plant observed both in May and in December of 2002. Carex lurida (shallow sedge, OBL),

Duchesnea indica (Indian strawberry, FACU-), and Panicum clandestinum (deer-tongue grass,

FAC+) were observed in December of 2002. Alliaria petiolata (garlic mustard, FACU-),

Podophyllum peltatum (mayapple, FACU), and Symplocarpus foetidus (skunk cabbage, OBL)

were observed in May of 2002. The canopy includes Acer rubrum (red maple, FAC) and

Fraxinus pensylvanica (green ash, FACW). The types of herbaceous vegetation present indicate

a fluctuating hydrology, typical of disturbed and frequently flooded areas.

Evidence of observed hydrology in Wetland 1 included saturation at a depth of 10.2 centimeters

(4.0 in), watermarks on trees, flooding debris, and surface drainage patterns. Water-stained

leaves were also present within the wetland. The primary source of hydrology for the wetland is

groundwater seeps and streamflow from the North Branch of Indian Run.

As indicated on the Wetland 1 field data sheets (Appendix B, W1-W1), the soil had a very dark

grayish brown (10YR 3/2) silty sand matrix, with gravel and no mottling. Auger refusal due to

rock occurred at 20.3 centimeters (8.0 in). Soils at this location were borderline, and typical of

floodplain and alluvial soils. However, the location of the wetland, adjacent to the waterway,

means that gravel and silt are deposited during periods of high flow. The area is functioning as a

wetland, and is supporting hydrophytic vegetation based on existing soils and hydrology.

2. Wetland 2. The wetland area is located north (upstream) of the S.R 4021 bridge.

Wetland 2 extends beyond the project study area. Wetland 2 within the project study area is

19.58 square meters (210.79 sq ft); the total size of Wetland 2 is 135.15 square meters (1454.79

sq ft). The wetland exists within a drainage swale along the eastern edge of the waterway. The

wetland and the waterway are separated by an upland bank. The wetland is classified as a PEM

community according to Cowardin (Cowardin et al. 1979).

As in Wetland 1, dominant species in Wetland 2 also include a mix of facultative wetland,

facultative, and facultative upland species. Panicum clandestinum, Smilax rotundifolia


(greenbriar, FAC), and Lonicera japonica (Japanese honeysuckle, FACU) were dominants

observed both in May and in December of 2002. Carex lurida, Ornithogalum umbellatum (star-

of-Bethlehem, FACU), and Phalaris arundinacea were observed in December of 2002.

Arisaema triphyllum (Jack-in-the-pulpit, FACW-), Erythronium umbilicatum (dimpled trout lily,

FAC), Podophyllum peltatum, and Symplocarpus foetidus were observed in May of 2002. The

canopy and understory includes Acer rubrum (red maple, FAC), Alnus incana (gray alder, NI),

Fraxinus pensylvanica, and Platanus occidentalis (American sycamore, FACW).

Evidence of observed hydrology in Wetland 2 included saturation and free water in the pit at a

depth of 10.2 centimeters (4.0 in), water marks on trees at the wetland edge as well as the upland

floodplain, flooding debris, and drainage patterns found in wetlands. Water-stained leaves, and

buttressing on mature trees were also observed. The primary source of hydrology for the wetland

is groundwater seeps, with streamflow from the North Branch of Indian Run during flood events

as a secondary source. The wetland discharges to the waterway.

As indicated on the Wetland 2 field data sheets (Appendix B, W2-W1), the soil profile had a

black (10YR 2/1) organic layer from 0.0 to 5.1 centimeters (0.0-2.0 in), and a black (10YR 2/1)

silty loam matrix with sand, with dark gray (10YR 4/1) mottles from 5.1 to 20.3 centimeters (2.0

to 8.0 in). Auger refusal due to rock occurred at 20.3 centimeters (8.0 in) throughout the wetland.

Soils at this location meet hydric soil criteria.

C. Upland Areas

1. Upland Woods. Within the project area, the forested uplands are located

upstream (north) and downstream (south) of the waterwayand within the 100-year floodplain of

the North Branch of Indian Run. Dominant vegetation south of the S.R. 4021 bridge (Appendix

B, W1-U1) includes Alliaria petiolata, Carex lurida, Duchesnea indica, Lonicera japonica,

Celastrus scandens (American bittersweet, FACU-), Ligustrum vulgare (privet, FACU), Rosa

multiflora (multiflora rose, FACU), and Rubus allegheniensis (Allegheny blackberry, FACU-).

Dominant canopy species include Fraxinus pensylvanica, Juglans nigra (black walnut, FACU),

and Platanus occidentalis. Vegetation in the uplands north of the S.R. 4021 bridge was similar to

North Buffalo Street and Industrial Parkway 12 Wetland Identification and Delineation Report

the downstream woods, but included additional canopy species, Fagus grandifolia (American

beech, FACU), and Carya ovata (shagbark hickory, FACU). Although snow remained on the

ground in December 2002, the soils in the uplands were moist but not saturated. No sign of

wetland hydrology was evident. The soils ranged from a sandy clay to a sandy clay loam, with

no sign of hydric soils.

2. Cultivated/Ornamental Banks. The upland area to the west of the waterway,

and upstream of the S.R. 4021 bridge, has been landscaped as part of the private residential land

adjacent to the project area. The area appears to be mowed occasionally and has ornamental

plantings. These plantings were not identified due to snow cover and the dormant season of

observation. These slopes are steeper than the surrounding landscape. No sign of hydrology was

observed along the steep upland slopes.
