1. Proposed Project The Texas Department of Transportation (TxDOT) proposes improvements to Interstate Highway 35 East (I-35E) from U.S. Highway (US 67) to Reunion Boulevard (Blvd.) and along US 67 from Interstate Highway 20 (I-20) to I-35E a total of approximately 11 miles in Dallas County, Texas. The proposed project is referred to as the “Southern Gateway Project.” 1.1 Existing Facility I-35E from Colorado Blvd. to Reunion Blvd. I-35E between Colorado Boulevard (Blvd.) and Reunion Blvd. consists of five northbound and four southbound mainlanes that include an 11-foot (ft) wide reversible high occupancy vehicle (HOV) lane. This section is currently under construction and was approved as part of the Dallas Horseshoe Project (CSJ. 0196-03-205, etc.) which received a Finding of No Significant Impact on September 18, 2012. Once construction is complete (anticipated 2018), the I-35E northbound bridge will consist of three mainlanes; two reversible HOV lanes, and five Collector Distributor (CD) lanes (to distribute traffic to Riverfront Blvd., I-30, or I-35E). The I-35E southbound bridge would consist of four mainlanes, four CD lanes (to collect traffic from Riverfront Blvd., I-30, and I-35E); and 6-ft sidewalks along the outside of each CD road. The right-of-way (ROW) at the Dallas Floodway crossing is approximately 848 ft wide. I-35E from US 67 to Colorado Blvd. and US 67 from I-20 to I-35E Along I-35E, the existing lane configuration from US 67 to 8th St. is eight mainlanes, four in each direction; with one reversible HOV lane. Along US 67 the existing lane configuration from I-20 to I-35E is four mainlanes, two each direction, with one concurrent HOV lane. South of 8th St., the existing ROW along I-35E varies from approximately 244 ft to 435 ft. The existing ROW along US 67 varies from approximately 305 ft to 469 ft. No bicycle or pedestrian accommodations exist along I-35E from 8th St. to US 67 or along US 67 from I-35E to I-20. 1.2 Proposed Facility The proposed project would consist of improvements to I-35E between US 67 and Reunion Blvd. and to US 67 between I-20 and I-35E. The improvements would consist of conversion of existing HOV lanes to reversible non-toll express lanes, addition of reversible non-tolled express lanes, addition of general purpose lanes (mainlanes), and bicycle and pedestrian accommodations. The proposed project is shown in Exhibit 1, and described below:

a) I-35E between Colorado Blvd. and Reunion Blvd.: Convert two reversible HOV lanes to two reversible non-tolled express lanes.

b) I-35E between US 67 and Colorado Blvd.: Full reconstruction to include two reversible non-tolled express lanes, widening of the mainlanes from 8 to 10, and increasing the number of frontage road lanes from 4 to 4/6.


CSJs: 0442-02-088, etc. 2 April 2016

c) US 67 from I-20 to I-35E: Partial reconstruction to change the existing concurrent HOV lane to one reversible non-tolled express lane within the existing median and widening the mainlanes from 4 to 6 along with slip ramp modifications.

The Dallas Horseshoe Project, under construction along I-35E, consists of two reversible non-tolled HOV lanes with 10 mainlanes that will tie into the proposed Southern Gateway Project at Colorado Blvd., providing a continuous corridor connection to Reunion Blvd. The non-toll express lanes would be open to all users including HOVs and would function as a general purpose lane with limited access.

2. Texas Conservation Action Plan (TCAP) Review

The Texas Conservation Action Plan (TCAP) is a conservation planning tool for all natural resources in the state. The purpose is to provide a statewide "roadmap" for research, restoration, management, and recovery projects addressing Species of Greatest Conservation Need (SGCN) and important habitats. SGCN include terrestrial, freshwater, and marine birds, mammals, reptiles, amphibians, invertebrates, fishes, plants and plant communities. The goal of the plan is ultimately to conserve and improve the status of these species and, as possible, prevent listings under the Endangered Species Act. The TCAPs were reviewed to identify the ecological region(s) in which the proposed project is located and to help identify potential SGCNs that may be present. It was also used to identify issues associated with transportation projects in the region. The study area consists of the existing and proposed ROW and easements and is within the Texas Blackland Prairies Ecoregion (TBPR) as described in the 2012 Texas Conservation Action Plan (TCAP). Due to historical changes in the landscape and vegetation, this ecoregion is considered critically threatened. The TBPR has been converted from historical tall grass prairies with abundant wildlife to mostly urban development and farmland. The TCAP identifies issues associated with transportation projects which may negatively affect SGCN populations, rare communities, and the habitats on which they depend in this region. Habitat fragmentation and habitat loss, including open-space land conversion, are broad issues that need to be addressed at various scales levels. Transportation improvements, whether upgrades of existing facilities or new construction, may create barriers to fish and wildlife resources daily and seasonal movements, opportunities for nonnative species invasions, water quality impacts through stormwater runoff, loss of nonjurisdictional wetlands, and impacts to important habitats that are not protected under current state or federal regulations. The transportation improvements proposed under The Southern Gateway Project are not expected to alter existing travel corridors to aquatic and terrestrial wildlife. The wooded riparian corridors containing streams are currently bridged and the proposed


CSJs: 0442-02-088, etc. 3 April 2016

design would also bridge these areas. Impacts would occur to these riparian corridors during construction activities. After construction is completed, the areas of bare ground resulting from the construction activity would be reseeded/revegetated according to TxDOT standards. Three SGCN species, cave myotis bat (Myotis velifer), Texas garter snake (Thamnophis sirtalis annectans), and Texas milk vetch (Astragalus reflexus) have the potential to occur within the study area. These species were determined based on the United States Fish and Wildlife Service (USFWS) and Texas Parks and Wildlife Department (TPWD) data. USFWS maintains a list of federally threatened and endangered species of potential occurrence for each Texas county which accessed through their website at https://ecos.fws.gov/ipac/. TPWD maintains a list of threatened and endangered species (both state and federallylisted) and state species of concern for each Texas county which was accessed through their website at http://tpwd.texas.gov/gis/rtest/. The proposed project would potentially impact riparian and disturbed prairie habitats. Texas milk vetch suitable habitat may be present along roadside ditches with clay soils which occur along US 67 from I-20 to Red Bird Ln. and again on US 67 around Sunny Glen Dr. Due to no proposed ROW at these locations and the existing ROW being maintained, it is unlikely for the Texas milk vetch to occur within the proposed project area. Potential impacts to these habitats within the study area would result from the clearing of the land for construction activities, covering part of the area with an impervious cover (concrete, rock, etc.), and revegetation of the remaining area. After construction activities are completed, the areas of bare ground would be reseeded/revegetated according to TxDOT standards in accordance with Executive Order (EO) 13112 on Invasive Species and the Executive Memorandum on Beneficial Landscaping. More specific details of impacts that may occur within the study area are detailed in the following sections of this document. The proposed project would consist of improvements to I-35E between US 67 and Reunion Blvd. and to US 67 between I-20 and I-35E. These existing roads currently provide a barrier to wildlife and their movements. The majority of the proposed project is located in an area mapped as urban. The proposed transportation improvements are not expected to alter existing travel corridors to aquatic and terrestrial wildlife.

3. Tier I Assessment Biological resources occurring in the study area were researched by desktop review of web resources from the TPWD, USFWS, US Department of Agriculture Natural Resources Conservation Service (NRCS), and TxDOT. Desktop mapping of biological resources was performed in a GIS mapping system using spatial data obtained from TPWD. Field reconnaissance was performed on March 25 and 26, 2014 and December 21, 2015 by a qualified biologist to examine and assess resources identified during desktop review and to identify and document any additional resources or other noteworthy biological features present in the study area. TPWD also maintains special species lists through the Texas Natural Diversity Database (TXNDD) by county. The TXNDD is a geo-referenced database of documented sightings of rare, threatened and endangered species of Texas. Data were obtained from TPWD on December 2, 2015 and reviewed on December 11, 2015. The TXNDD review met all the requirements of the TxDOT-TPWD Memorandum of Understanding (MOU) for sharing and maintaining TXNDD information. 3.1 Existing Wildlife Wildlife species observed and noted during the field reconnaissances included the common grackle (Quiscalus quiscula), Northern mockingbird (Mimus polyglottos), house finch (Carpodacus mexicanus), Northern cardinal (Cardinalis cardinalis), tufted titmouse (Baeolophus bicolor), Carolina wren (Thryothorus ludovicianus), European starlings (Sturnus vulgaris), and the Eastern fox squirrel (Sciurus niger). Unidentified minnows and a turtle were also noted at Fivemile Creek. Species signs that were observed included the common raccoon (Procyon lotor) and the Virginia opossum (Didelphis virginiana). Wildlife is generally typical for what may be expected in rural/suburban areas in the southern portion of US 67 and more urban areas in the northern portion of the project. Tracks of animals like the coyote (Canis latrans), raccoon (Procyon lotor), and the striped skunk (Mephitis mephitis) may be found along the streams in the southern portion of the project where conditions allow and even within the existing ROW. Reptiles and amphibians like the blotched water snake (Nerodia erythrogaster transversa), the broad-banded water snake (Nerodia fasciata confluens), the rough green snake (Opheodrys aestivus), the six-lined racerunner (Cnemidophorus sexlineatus sexlineatus), the Midland smooth softshell (Trionyx muticus muticus), and the ground skink (Scincella lateralis) can also be seen on occasion in the same general area. Birds like the western kingbird (Tyrannus verticalis), downy woodpecker (Picoides pubescens), yellow-billed cuckoo (Coccyzus americanus), mourning dove (Zenaida macroura), and the scissor-tailed flycatcher (Tyrannus forficatus), along with many other avian species, may be considered somewhat common in the southern portion of the project. Most, if not all, of these species may still be found in the northern portion of the project, but not as commonly, because the area is much more developed and urbanized except for a few isolated tracts and pockets along existing streams and creeks. In the


CSJs: 0442-02-088, etc. 5 April 2016

northern portion of the project, the green anole (Anolis carolinensis), the plains blind snake (Leptotyphlops dulcis dulcis), the ground skink, the Texas spiny lizard (Sceloporus olivaceus), and the Texas rat snake (Elaphe obsoleta lindheimeri) are the more commonly found reptiles. In urban areas, such as those found toward the northern portion of the project, the common grackle (Quiscalus quiscula), northern mockingbird (Mimus polyglottos), house finch (Carpodacus mexicanus), European starling (Sturnus vulgaris), and northern cardinal (Cardinalis cardinalis) are much more commonly seen avian species. Mammals such as those found in the southern portion of the project can again be found in the northern portion of the project, but usually in smaller numbers. Many of these mammals use riparian woodlands along rivers, streams, and creeks as travel corridors and for foraging. Depending upon local conditions, small populations of these mammalian species may exist for years in these areas. Also, some mammalian species can readily adapt to man’s environment and urbanization and may live among human residential and commercial developments without being noticed to any real extent. It has been determined that coordination with TPWD is required per the 2013 TPWD/TxDOT MOU. The Tier 1 Site Assessment, contained within the Biological Evaluation form, has been uploaded to the Environmental Compliance Oversight System (ECOS) for the proposed project. 4. EMST Review Based on the field surveys conducted on March 25 and 26, 2014, adjustments were made to the EMST vegetation values to better reflect existing conditions. The existing (adjusted) habitat types in the study area consist of approximately 577.22 acres of urban habitat, 33.28 acres of floodplain habitat, 5.35 acres of riparian habitat, 2.83 acres of Edwards Plateau savanna, woodland, and shrubland habitat, 0.62 acres of disturbed prairie habitat, no tallgrass prairie and grassland, and no agriculture habitat within the study area (Exhibit 2). There are various locations containing fenceline vegetation scattered throughout the study area, four locations of riparian vegetation, and nine large trees (18-inch diameter at breast height (DBH) or greater) located within the study area. The MOU habitat types from the TPWD EMST Mapper and the actual habitat types, verified by a qualified biologist, within the existing and proposed ROW limits are shown in Table 1. The associated habitat acreage amounts for the EMST mapped habitat and actual habitat are also in the table. Exhibit 2 shows the mapped MOU habitat type on the top of each sheet and the adjusted MOU habitat type from field observations on the bottom. In addition to the habitat present within the study area, Table 1 includes the potentially impacted habitat acreage. Based on the actual habitat present, the potential impacts were calculated for each habitat type from the edge of proposed pavement where new construction would occur. All potential habitat impacts were considered as permanent


CSJs: 0442-02-088, etc. 6 April 2016

and would represent the worse-case scenario. The potential impacts for each habitat type were compared to the MOU Programmatic Agreement (PA) habitat threshold amounts to determine if the potential impacts would exceed the MOU PA thresholds. Potential impacts were not calculated for the urban habitat type as this type does not have a threshold amount per the MOU PA. The MOU PA threshold amount for each habitat type is also included in Table 1. The potentially impacted habitat areas are shown on Exhibit 2 with a red outline and the acreage amount for each area is included.

Riparian habitat is limited to vegetation associated with three waterways. The trees range in height from approximately 10 to 40 ft and contain a DBH from 1 to 28 inches. The average DBH is approximately 8 inches and the percent canopy cover is approximately 35 percent. Because the adjacent areas are maintained, the riparian vegetation is not able to expand further. Approximately 1.67 of the 5.35 acres of riparian habitat could be permanently impacted as a result of the construction of the proposed project. The proposed project would exceed the 0.1 acre PA threshold for riparian habitat. The riparian and floodplain habitat located at the Trinity River would not be impacted as no construction activities would occur at this location for the proposed project. Approximately 0.53 of the 0.62 acre of disturbed prairie habitat present would be considered permanently impacted as a result of the construction of the proposed project. The proposed project would not exceed the 3.0 acre PA threshold for disturbed prairie habitat. Riparian vegetation associated with the water features are located within three of the identified waters features. After construction is completed, the areas of bare ground resulting from the construction activity would be reseeded/revegetated according to TxDOT standards. All other habitat types would not exceed the associated PA thresholds.

5. Existing Vegetation

5.1 Edwards Plateau Savannah, Woodland, and Shrubland

Edwards Plateau Savannah, Woodland, and Shrubland areas contain trees, shrubs, and grasses associated with undeveloped sites. These areas have potential to provide habitat for various wildlife species. However, due to habitat fragmentation, certain species that have adapted more readily to co-exist with an urban environment can utilize some of these vegetated woodland areas for foraging and habitat. Vegetation observed included eastern red cedar (Juniperus virginiana), sugarberry (Celtis laevigata), cedar elm (Ulmus crassifolia), pecan (Carya illinoinensis), Bermuda grass and various forbs. Small areas of woodlands are observed adjacent to the study area. 5.2 Riparian and Floodplain The TPWD EMST Mapper identified Riparian and Floodplain habitat types within the study area. Based on field observations, riparian habitat is limited to vegetation associated with the Trinity River at I-35E and Cedar Creek at US 67. Floodplain vegetation is associated with the Trinity River at I-35E. Vegetation associated with these areas is limited to the aquatic feature margins and banks due to urban development and mowing. The corridors range from approximately 35 to 150 feet wide with trees ranging in height from approximately 10 to 40 feet. Riparian habitat comprises 5.35 acres of the study area and floodplain habitat comprises 33.28 acres of the study area. These habitat types provide soil conservation, habitat biodiversity, and influence food and cover for fish, reptiles, resident and migratory birds, small mammals, invertebrates, and the predators that feed on the other species. These areas can provide important nesting and foraging habitat for birds and waterfowl. Vegetation observed along the waterways included yaupon (Ilex vomitoria), sugar hackberry (Celtis laevigata), red cedar (Juniperus virginiana), box elder (Acer negundo), greenbrier (Smilax spp.), chinaberry tree (Melia azedarch) black willow (Salix nigra), green ash (Fraxinus pennsylvanica), American elm (Ulmus americana), cedar elm (Ulmus crassifolia), eastern cottonwood (Populus deltoides), chinaberry, and various grasses and forbs. 5.3 Tall Grass Prairie, Grassland The TPWD EMST mapped grassland habitats within the study area are considered Urban and consisted of Bermuda grass (Cynodon dactylon), switchgrass (Panicum virgatum), little bluestem (Schizachyrium scoparium), green sprangletop (Leptochloa dubia), and buffalograss (Buchloe dactyloides). These area classifications were minimal, mowed and very well maintained. 5.4 Urban and Disturbed Prairies Urban areas contain trees, shrubs, and grasses associated with unmaintained properties. These areas provide minimal habitat for wildlife; however, certain species


CSJs: 0442-02-088, etc. 8 April 2016

that have adapted more readily to co-exist with an urban environment can utilize some of these vegetated urban areas for foraging and habitat. Vegetation observed included live oak, red oak (Quercus texana), Arizona ash (Fraxinus velutina) sugar hackberry, chinaberry, Bermuda grass, little bluestem, green sprangletop, buffalograss, dallisgrass, and various forbs. 6. Unusual Vegetation Features and Special Habitat Features The locations of fenceline vegetation varies throughout the study area with greater concentrations in the southern portion of the study area. Areas of fenceline vegetation exhibited variable vegetative growth and included sugarberry, cedar elm, Hercules club (Zanthoxylum clava-herculis), honey locust (Gleditsia triacanthos), yaupon (Ilex vomitaria), bois d’arc (Maclura pomifera), and basswood (Tilia caroliniana). Some fenceline areas are adjacent to undeveloped vacant lots.

Based on the current level of design, approximately six large trees and approximately 1.67 acres of riparian habitat could be impacted by the proposed construction activities (Table 2). Efforts to protect the trees and riparian habitat during construction would occur as it may be possible to preserve those located near the edge of the construction areas.

7. Threatened and Endangered Species and Species of Greatest Conservation Need (SGCN)

The limits for this proposed project are situated within the Cedar Hill, Dallas, Duncanville, and Oak Cliff USGS topographic quadrangle maps. The proposed project crosses over the Dallas Floodway which is routinely maintained by mowing and selective removal of woody vegetation. Outside of the levees within the study area, the area exhibits urban development of various types, such as commercial, industrial, and residential development, with some isolated pockets of undeveloped land. Table 3 provides the USFWS and TPWD threatened, endangered, and species of concern for Dallas County. Reconnaissance level surveys were conducted in March 2014 and December 2015 to determine habitat availability within the study area for listed species.

E – State or Federal Listed Endangered T – State or Federal Listed Threatened C – Federal Candidate for Listing R – Federal Recovery SGCN – Species of greatest conservation need “blank” – For Federal listing means there is no designation occurring within identified county “blank“ – State listed Rare, but with no regulatory listing status Sources: US Fish & Wildlife Service (January 12, 2016), Texas Parks & Wildlife Department, Wildlife Division, Diversity and Habitat Assessment Programs, County Lists of Texas Special Species (December 2, 2015), and Field Visit (March 25 and 26, 2014).

Eleven species have potential habitat within the study area and ten of these species, listed in Table 3, may be impacted by the proposed project. None of the species that could be potentially impacted are federally recognized species. Therefore, there will be no effect to federal threatened, endangered, or candidate species or designated critical habitat. Plains spotted skunk is state listed as rare, three species (cave myotis bat, Texas garter snake, Texas milk vetch) are SGCN, and six species (wood stork, Louisiana pigtoe, Sandbank pocketbook, Texas heelsplitter, Texas pigtoe, and the timber/canebrake rattlesnake) are state listed as threatened.


CSJs: 0442-02-088, etc. 16 April 2016

Four species (Louisiana pigtoe, sandbank pocketbook, Texas heelsplitter, and the Texas pigtoe) with potential habitat that may be impacted are the state listed threatened species of mussels. According to TXNDD, three state threatened mussel species that have a record of occurring within the project limits are the Louisiana pigtoe, sandbank pocketbook, and Texas pigtoe at the Trinity River. Because work at the Trinity River would consist of conversion of HOV lanes to express lanes, no ground disturbance or impacts to the river would occur. Other streams in the study area may have potential habitat for state listed mussels. As a precautionary measure, for Freshwater Mussels, the Freshwater Mussel Best Management Practices (BMPs) will be included on the Environmental Permits, Issues, and Commitments (EPIC) sheet. These are:

When work is in the water; survey project footprints for state listed species where appropriate habitat exists.

When work is in the water and mussels are discovered during surveys; relocate state listed and SGCN mussels under TPWD permit and implement Water Quality BMPs.

When work is adjacent to the water; Water Quality BMPs implemented as part of the SWPPP for a construction general permit or any conditions of the 401 water quality certification for the project will be implemented. (Note, SWPPP and 401 BMPS are not listed in this PA). No TPWD Coordination is required.

The wood stork may be impacted by the project but it is unlikely. The main area with potential habitat for the state listed species is within the Trinity River levees. As with the mussel species, because this area will not be impacted, the likelihood of impacting the wood stork is extremely low. As a precautionary measure, bird BMPs are included in the project EPIC sheet. The cave myotis bat, Texas garter snake, and Texas milk vetch are the three SGCN species that could be impacted during the project. The cave myotis bat has the potential to occur under bridges throughout the project corridor. While no bat colonies were noted during the field investigation in March, 2014, there is the potential for bats to occur within the study area. Prior to demolition of bridges, a sight inspection should be conducted to ensure a myotis bat colony does not inhabit the bridge. Bridge bat and cave bat BMPs will also be implemented. The Texas garter snake prefers wet or moist habitats which occur along the various creek crossings throughout the study area. Due to the abundance of available habitat within and adjacent to the project, the potential impacts to the riparian areas within the study area are not anticipated to adversely impact the Texas garter snake. Per BMPs, contractors will be advised of potential occurrence in the study area, and to avoid harming the species if encountered. BMPs would be included in the EPIC sheets. Disturbance to the habitat would occur during construction, but after construction is complete, normal water flow levels and re-vegetation of the crossing would occur. No long term impacts are anticipated to occur to the Texas garter snake population. Texas milk vetch was not noted during the March 2014 field investigation; however, there is the potential for Texas milk vetch to occur within the study area. A species-specific BMP for Texas milk vetch is not included in the TxDOT-TPWD BMP PA and therefore is a trigger for coordination with TPWD.


CSJs: 0442-02-088, etc. 17 April 2016

Both the plains-spotted skunk and the timber/canebrake rattlesnake have varying preferred habitats which can range from farmlands to woodlands. The plains-spotted skunk prefers open fields, prairies, croplands, forest edges, woodlands, and wooded brushy areas. The timber/canebrake rattlesnake can be found in swamps, floodplains, upland prairies, deciduous woodlands, riparian areas, or other areas that have dense ground cover. Because several riparian areas and wooded areas are located within the study area, there is the potential for the two species to occur within the study area. The project may impact the species during construction, but would have no lasting impacts. Per BMPs, contractors will be advised of potential occurrence in the study area, and to avoid harming the species if encountered, and to avoid unnecessary impact to dens. The BMPs would be included in EPIC. Overall, there is minimal habitat for wildlife species beyond the limits of most of the study area due to urban development. No long-term impacts to wildlife populations are anticipated as a result of the proposed project. In areas temporarily impacted, wildlife species adapted to urban areas would likely re-colonize the available habitat areas after construction. Burrowing species or less mobile species would be more susceptible to impacts from construction activity. MBTA Between October 1 and February 15, the contractor would remove all old migratory bird nests from any structures that would be affected by the proposed project, and complete any bridge work and/or vegetation clearing. In addition, the contractor would be prepared to prevent migratory birds from building nests between February 15 and October 1, per the EPIC plans. In the event that migratory birds are encountered on-site during project construction, adverse impacts on protected birds, active nests, eggs, and/or young would be avoided. Due to overall lack of available habitat within the study area, the impacts to wildlife would be considered minor. 8. Texas Natural Diversity Database (TXNDD) Review Table 4 provides the TXNDD element occurrences within 10 miles of the proposed project. The TXNDD is a previous detection database that cannot be interpreted as presence/absence data. The TXNDD database search is available for review in Attachment B. TXNDD review revealed that there are three state threatened species within 1.5 miles of the study area: the Texas pigtoe (Fusconaia askewi), Louisiana pigtoe (Pleurobema riddellii), and sandbank pocketbook (Lampsilis satura). Habitat for the Texas pigtoe, Louisiana pigtoe, and sandbank pocketbook is present at the Trinity River within the study area. Proposed work at the Trinity River will take place on structures being constructed as part of the Horseshoe Project. No new construction would occur at the Trinity River as a result of the proposed project.

9. Aquatic Features A total of 11 features were identified within the study area, eight water features and three wetland features. All eight of the water features noted during the field investigation were also identified as mapped waterbodies (blue lines) on the USGS topographic maps. The water and wetland features total approximately 15.16 acres. The features identified within the study area consist of emergent wetlands and perennial, intermittent, and ephemeral streams. The emergent wetlands are located within the Trinity River floodplain and are mapped as floodplain. The streams are located throughout the study area. Of the eight water features, one is located within a culvert in the study area, one is contained within a natural, or earthen streambed, and six water features are spanned by bridge structures. The feature within a culvert primarily has herbaceous vegetation associated with it. The features spanned by a bridge have been limited on their ability to revegetate to a more natural state due to the presence of hardscape materials such as gabions and maintenance activities. Woody and herbaceous vegetation are associated with these features. Each of the wetland features are dominated by herbaceous vegetation. Refer to the Water Resources Technical Report for additional information. Upland drainage features are also present within the study area. These are man-made features constructed in uplands to collect and drain stormwater runoff from the roadways and adjacent developed areas. Small areas within the drainage features may allow water to pool for short periods allowing growth of hydrophytic vegetation. However, these are considered upland drainage features and not water or wetland features. The proposed project would not result in a significant permanent impact to the overall health of the water resources within the study area. It is estimated that approximately 0.004 acre of permanent fill impacts to three potentially jurisdictional water features. No temporary or permanent impacts to wetlands would occur. BMPs would be implemented to reduce and limit impacts to the area water resources during construction activities. Use of Nationwide Permits (NWPs) would satisfy the requirements of this project. A Preconstruction Notification would not be required for the proposed project. Mitigation would not be required for the permanent impacts. If temporary fills are needed in potentially jurisdictional waters then the temporary fills would be removed and the affected areas would be returned to their pre-existing elevations.


CSJs: 0442-02-088, etc. 20 April 2016

10. Additional Information 10.1 Topography and Soils The topography of the study area reflects a gentle slope from south to north and from east to west. The I-35E segment has an elevation at the north of 410 feet and extends upward to an elevation of 650 feet at the south. The US 67 segment of the project has an elevation of 550 feet and extends upward to an elevation of 800 feet at the southern terminus. According to the NRCS Soil Survey of Dallas County, Texas (1980), there are three general soil types within the study area. The Eddy-Stephen-Austin is very shallow to moderately deep and gently sloping to moderately steep loamy and clayey soils on uplands. The Trinity-Frio is deep, nearly level clayey soils on floodplains. The Austin-Houston Black is deep, nearly level to sloping clayey soils on uplands. Permanent soil erosion control features would be constructed as soon as feasible during the early stages of construction through proper sodding and/or seeding techniques. Disturbed areas would be restored and stabilized as soon as the construction schedule permits and temporary sodding would be considered where large areas of disturbed ground would be left bare for a considerable length of time. 10.2 Farmland Protection Policy Act The NRCS Web Soil Survey does contain one soil type designated as a “farmland of statewide importance” (Austin silty clay, 1-3 percent slopes) and one soil type designated as “all areas prime farmland” (Dalco clay, 1-3 percent slopes). These two soil types are located within the existing TxDOT ROW at, and north of, the US 67 and I-20 interchange. No additional ROW is needed for the proposed project at this location. The proposed project is not subject to FPPA requirements.

11. Environmental Permits, Issues and Commitments (EPIC)

BMPs from the TxDOT/TPWD PA will be utilized for the listed species that could occur within the study area. The following BMPs would be included in the EPIC sheets:

Bird BMPs will be used for all migratory bird species and include:

Not disturbing, destroying, or removing active nests, including ground nesting

birds, during the nesting season;

Avoiding the removal of unoccupied, inactive nests, as practicable;

Preventing the establishment of active nests during the nesting season on

TxDOT owned and operated facilities and structures proposed for replacement or

repair;


CSJs: 0442-02-088, etc. 21 April 2016

Not collecting, capturing, relocating, or transporting birds, eggs, young, or active

nests without a permit.

Cave myotis bat BMPs include: Bridge Bat BMPs

Survey by a qualified biologist to determine if bats are present.

If bats are present take appropriate measures as practical to ensure that bats are

not harmed such as exclusion or timing activities. For maternity colonies,

exclusion activities should be timed to avoid separating lactating females from

nursing pups.

If structures used by bats are removed as a result of construction, replacement

structures should incorporate bat-friendly design, or artificial roosts should be

constructed to replace these features as practical.

Cave/Cliff Bat BMPs

When TxDOT activities have the potential to impact cliffs or caves adjacent to roadways, these features will be surveyed by a qualified biologist to determine if bats are present.

Newly acquired TxDOT ROW will be surveyed by a qualified biologist for

cliff/cave features. Conversion of property containing cave or cliff features to

transportation purposes should be avoided where feasible.

If bats are present take appropriate measures as practical to ensure that bats are

not harmed such as exclusion or timing activities. For maternity colonies,

exclusion activities should be timed to avoid separating lactating females from

nursing pups. If features used by bats are removed as a result of construction,

artificial roosts should be constructed to replace these features as practical.

Freshwater Mussel BMPs include:

When work is in the water; survey project footprints for state listed species where

appropriate habitat exists.

When work is in the water and mussels are discovered during surveys; relocate

state listed and SGCN mussels under TPWD permit and implement Water

Quality BMPs.

When work is adjacent to the water; Water Quality BMPs implemented as part of

the SWPPP for a construction general permit or any conditions of the 401 water

quality certification for the project will be implemented. (Note, SWPPP and 401

BMPS are not listed in this PA). No TPWD Coordination required.

Texas garter snake BMPs include:

Contractors will be advised of potential occurrence in the study area, and to avoid harming the species if encountered.


CSJs: 0442-02-088, etc. 22 April 2016

MBTA Between October 1 and February 15, the contractor may remove all old migratory bird nests that would be affected by the proposed project and complete vegetation clearing. If any active nests are found during construction activities, the contractor shall cease work in that immediate area and contact the TxDOT project manager who would contact, as needed, the local USFWS office or local TPWD office. The Bald Eagle has the potential to migrate through the area. However, there is no suitable foraging or roosting habitat for the Bald Eagle within the study area and therefore is not expected to occur within the study area as determined by a qualified biologist. Due to the lack of suitable habitat, the National Bald Eagle Management Guidelines of 2007 is not applicable. Texas milk vetch does not have a species-specific BMP at this time and is, therefore, a trigger for coordination with TPWD. Disturbed areas would be re-vegetated with herbaceous species and stabilized as soon as the construction schedule permits and temporary sodding would be considered where large areas of disturbed ground would be left bare for a considerable length of time. Reseeding will be completed in compliance with TxDOT requirements. The project is FPPA exempt because the project is within areas designated for development; therefore, no coordination with NRCS is required.
