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
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.
