Project Details

Coastal Resources, Inc. (CRI) conducted natural resource surveys within a 9.5-mile section of the Church to Steele transmission line project between Duhamel Road and Sandtown Road in Queen Anne’s and Caroline counties, Maryland.  Wetlands and waterways were identified and delineated in the field within the approximately 300-foot wide corridor using the Regional Supplement to the Corps of Engineers Wetland Delineation Manual: Atlantic and Gulf Coastal Plain Region (USACE July 2010).  In addition to flagging the boundaries of all observed wetlands/waterways, CRI staff were responsible for gathering field data on hydrology, soils, and vegetation and completing functional assessments on wetlands greater than 0.5 acre in size using the New England Method.  CRI staff delineated 44 wetland/waterway systems and completed detailed wetland delineation and functional assessment data sheets for each system.  CRI prepared a final wetland delineation report that summarized conditions of all wetland/waterways.  The report also included wetland/waterways and functional assessment data sheets, photographs of each system, and field mapping.

CRI also planned and carried out a habitat characterization along a 25.5 mile long transmission line corridor to document the presence of suitable habitat for rare, threatened, or endangered (RTE) plant and animal species.  The assessment targeted potential Delmarva Bay habitat within the corridor known to support the presence of several RTE plant and animal species.  Eight (8) Delmarva Bays were documented in the corridor.  Beginning in March, CRI staff organized and led tiger salamander egg mass surveys of the targeted Delmarva Bays.  Three (3) separate surveys were performed within each bay over a 3 week period.  No tiger salamander egg masses were discovered.  CRI staff also planned and led dipnet surveys in May/June for tiger salamander larva and in June/July for barking treefrog larva.  No tiger salamanders or barking treefrogs were found, though surveys were successful for both species at a nearby reference site.  Plant surveys were also carried out between April and October to document the presence of targeted RTE plant species within the corridor.  Seven (7) of the 11 RTE plant species documented by DNR to occur in the vicinity of the project were found during the surveys.  An additional 8 RTE species were found.  Results of the survey efforts and documented plant species found were summarized in a detailed targeted species report submitted to DNR for review. CRI staff also prepared RTE Element Occurrence forms for DNR that summarized the details of each found population or individual within the project corridor to update DNR’s RTE database.
