Biological Assessment (BA), — • Engineer shall prepare and coordinate the submittal of the BA in accordance with USACE guidance and described in more detail in the following (services to be provided by subconsultant SWCA): • Endangered Species Act (ESA) compliance in support of a pre - construction notification (PCN) to the U.S. Army Corps of Engineers (USAGE) Fort Worth District. There are two proposed waters of the U.S. (WOTUS) crossings within the project right-of-way: Brushy Creek (a perennial stream) and Dry Fork Creek (an open water impoundment on an intermittent stream). There are two roadway alternatives proposed for the crossing at Dry Fork Creek: a three -span bridge with drilled pier foundations (Option 1), and a floorless arch culvert with spread footings (Option 2). At Brushy Creek, a bridge span is proposed for the road crossing. No permanent impacts are anticipated from construction of the bridge span. For the two WOTUS crossings, authorization under Nationwide Permit 14 (Linear Transportation Projects) is proposed. The Project crosses designated subsurface critical habitat for the Jollyville Plateau Salamander (Eurycea tonkawae) at Dry Fork Creek. Therefore, SWCA is to prepare a Biological Assessment (BA) to assess the effects of the Project on the Jollyville Plateau Salamander, as well as protected species known to occur in the Project action area. The BA would be drafted to support informal Section 7 consultation with the U.S. Fish and Wildlife Service (USFWS) via the USAGE Fort Worth District as the lead federal agency. Exhibit B Wyoming Springs Segment 1 -Final Design and Permitting Page 10 of 20 BIOLOGICAL ASSESSMENT • Recently, the USACE Fort Worth District Regulatory Division provided SWCA with draft BA guidance, which included required elements for a BA. SWCA will use the guidance to develop an outline and draft the components of the BA before submitting to the USACE. The USACE also suggests that the applicant incorporate additional resources provided by the appropriate USFWS office for guidance on the development of BAs. In addition, SWCA senior wildlife biologists that holds a USFWS Section 10(A)(1)(A) Permit will be conducting a one - day site visit to assess and map potential Jollyville Plateau salamander and golden-cheeked warbler habitat within the Action Area for the BA. The following components are a comprehensive list of information required by the USACE for the development of the BA as quoted by the draft BA guidance provided by the USACE: 1. Introduction a. State the purpose of document (e.g., to assess the effects of the proposed action on federally protected resources). b. Briefly specify the proposed action. If applicable, include both the Federal action (e.g., issuance of Nationwide Permit 14) and the applicant's action (e.g., roadway construction). 2. Project Description a. Subdivide proposed action into project elements (e.g., construction, operation, and maintenance), if applicable. b. Describe the where, when, and how for each Project element. c. Include a map delineating the location of each Project element. d. Identify any conservation measures that will be incorporated into the Project design. 3. Action Area a. Delineate the geographic area that will be affected(ie., the area where the physical, chemical, and biotic effects will occur). b. Delineate the specific areas that will affected by each of the Project elements. C. Identify any ongoing activities that may be affecting the species or habitat. 4. Species/Critical Habitat Considered a. Identify the species or critical habitat that "may be present. " b. Document how you identify these listed resources. c. Describe the current population and habitat conditions (status and trend, if known) in the action area for each protected resource that " may be present. " Exhibit B Wyoming Springs Segment 1 -Final Design and Permitting Page 11 of 20 5. Effects Analysis a. For each species or critical habitat parcel, explain how it will or will not be exposed to the Project elements; be sure to consider effects to all life stages. b. Describe the anticipated response (e.g., none, abandoned the area, decrease foraging success, reduced fecundity, injury, death, etc.) from any likely exposure. c. Cumulative Effects Analysis (for actions that are likely to adversely affect listed resources). Identify any future state or private activities, not involving Federal activities that are reasonably certain to occur within the action area. Describe how such activities will affect listed resources within the action area. 6. Conclusion and Determination of Effects for each protected resource a. For each protected resource, make a Section 7 determination and include your rationale. ASSUMPTIONS • The USACE, as the lead federal agency, will coordinate with the USFWS. Other than initial contact with the USFWS regarding agency - specific recommendations (e.g., Action Area) for the BA, SWCA will not have contact with the USFWS regarding the Project. • The cost below is based on the required components provided in the USACE draft BA guidance. If the USFWS requires or recommends items for the BA that differ greatly than the USACE guidance, a change order may be required. • SWCA will provide draft and final copies of the BA (in electronic format) to Halff Associates, Inc. for one round of review prior to agency submission. • SWCA will respond to up to three rounds of comments from the USACE with the assumption these comments will be include any comments from the USFWS.
