APPENDIX Effects Pathways Matrix Survey Data Monitoring and Reporting Plan 1. Executive Summary Introduction The Angie Creek bridge replacement and stream restoration project, located in Labrador County, California is being proposed by the California Transportation Department (CALTRANS) to remove an existing aging culvert and replace it with a larger single span that will accommodate storm surge flows. The project includes restoration to properly functioning condition of the entire stream channel from the bridge site to the Laurietor Wetlands (approximately one mile downstream). Demolition, construction and restoration activities are anticipated to take two years. Species and Effect Determinations The following species list was provided by IPaC for the action (print out and include in Appendix) area of this project: SPECIES LISTING DETERMINATION STATUS California Red-Legged Frog Threatened Likely to adversely affect California Red-Legged Frog critical habitat Designated Likely to adversely affect Nicolaysen’s blue dragonfly Endangered No effect Englelily Proposed No effect CALTRANS has determined that the project will have no effect on Nicolaysen’s Blue Dragonfly and Englelily. The closest occurrence of Nicolaysen’s Blue Dragonfly is 13 miles east of the action area, where unique soils maintain seeps adequate for egg deposition. The Englelily is found in habitats occupied by Nicolaysen’s blue dragonfly and the species has never been observed within 20 miles of Angie Creek. Therefore these two species will not be discussed further in this Biological Assessment. 2. Project Description Location The Yvonne Road Bridge over Creek (Figure 1) is located 5 miles west of Gruell, between mile markers 17 and 18 in Labrador County (Lat/Longs) (Figure 2).
