General, Clean Water Act, Section 404 Permits


Blackbird has obtained several Clean Water Act, Section 404 General Permits for proposed commercial and residential developments. The preconstruction notifications included Preliminary Jurisdictional Determinations (PJD); summary Biological Evaluations (BE); avoidance and minimization summaries; comprehensive mitigation plans and evaluations of direct and indirect impacts.


Protected Species Surveys


Blackbird completed several American burying beetle (Nircrophorus americanus) (ABB) presence/absence surveys. The ABB surveys were completed according to the USFWS’ (2009) survey guidance. The published survey guidance is based on Creighton et al. (1993) and Bedick et al. (2004). The surveys were completed to determine if additional best management practices would be required to avoid take of ABB during commercial construction activities.


Environmental Specialist Studies for Transportantion Projects


The studies required a reveiw for potential jurisdictional waters, including wetlands and other waters of the U.S. as defined in the Clean Water Act (CWA). Waterbodies on site were delineated in accordance with the 1987 U.S. Army Corps of Engineers (USACE) Wetland Delineation Manual and classified according to Cowardin et al. (1979). Each PJD included waterbody specific information required for CWA, Section 404 permit application. Blackbird also performed a characterization of habitat within each proposed action area. The habitat characterization evaluated potential project impacts on federal and state listed candidate, threatened and endangered species. Effects determinations were provided for all listed species.
