Project Details

Coastal Resources Inc. (CRI) is a subconsultant on this multi-year open-end contract with the Montgomery County Department of Environmental Protection (MCDEP).  CRI provides stream assessment and restoration design support, physical and biological monitoring, and natural resource assessments and permitting.  Example tasks are described below:

Watershed Restoration Project Pre- and Post-Construction Restoration Effectiveness Monitoring

CRI is currently conducting pre- and post-construction monitoring of Montgomery County’s watershed restoration projects over a five year period.  While CRI is a subconsultant on the overall contract, CRI is the technical lead and reporting lead for this task.  Monitoring includes benthic macroinvertebrates, vernal pools, stream salamanders, freshwater mussels, fish, temperature, wetland vegetation, botanical reforestation, quantitative in-stream habitat, qualitative aquatic habitat, in-situ water chemistry, and hydrologic monitoring up and downstream of, and within restoration project limits to determine baseline and post-construction conditions.  Benthic macroinvertebrate and fish sampling is conducted according to MBSS field protocols, while MCDEP protocols are followed for all other parameters.  To meet the requirements of the contract, CRI attends MBSS training annually as well as a calibration/training day with MCDEP for each sampling season.  Data analysis and reporting are conducted for each restoration project to combine the various monitoring parameters and determine the overall success or failures of projects.  CRI follows rigorous QA/QC procedures for all aspects of the project including staff training, certification, calibrations, data entry checks, field data collection checks and other measures as issues are identified.  The effort entails close and constant coordination with MCDEP through all project components, including field work planning, data submittals, and collaboration on reports that integrate County background information with annual monitoring data.

As part of this task, CRI also assisted in the completion of the Anacostia Watershed Stream Assessment subtask to provide stream and watershed inventory data to MCDEP for their use in developing restoration priorities for streams in the Anacostia Watershed.  CRI participated in qualitative watershed assessments on 50 linear miles of stream to identify potential impairments to streams including erosion, channel alteration, inadequate riparian buffers, debris problems, and fish barriers using the Stream Corridor Assessment (SCA) methodology developed by the Maryland Department of Natural Resources. CRI also identified stormwater outfalls and potential failures and contributions to downstream erosion. EPA’s Rapid Bioassessment Protocol (RBP) was utilized to classify representative sites based on instream and riparian habitat characteristics.  GPS and ArcMAP were used to create shapefiles and calculate the percent of each reach with impairments.

Kensington and Aspen Hill Libraries, Low Impact Development Projects

Under this contract task, CRI delineated wetlands and waterways for two proposed rain gardens and two infiltration trenches intended to capture, treat and infiltrate runoff on library grounds.  CRI conducted a Natural Resources Inventory (NRI) and Forest Stand Delineation (FSD) in accordance with Maryland-National Capital Park and Planning Commission (M-NCPPC) Environmental Guidelines. CRI created the NRI/FSD map and prepared the FSD narrative, in adherence with M-NCPPC requirements for the project.  CRI coordinated with M-NCPPC staff to obtain plan approval and prepared an approved Tree Save Plan.
