Coastal Resources, Inc. (CRI) was responsible for the existing conditions and environmental effects sections of the Draft Environmental Impact Statement (DEIS) and Final Environmental Impact Statement (FEIS) for waters of the U.S., including wetlands, forests, rare threatened and endangered species, groundwater, terrestrial and aquatic habitat. CRI also prepared a Natural Environment Technical Report (NETR) in support of the DEIS and a Water Resources Technical Report in support of the FEIS. A detailed wetland delineation was conducted as part of the Purple Line project, a 16 mile proposed transit corridor in Montgomery and Prince George’s Counties, and an Approved Jurisdictional Determination (JD) was obtained during the FEIS phase. All waters of the U.S., including wetlands, were identified using the US Army Corps of Engineers (USACE) Coastal Plain and Eastern Mountain and Piedmont supplements. CRI conducted detailed wetland delineations and forest assessments along all proposed alternatives and options. Wetland boundaries were surveyed using GPS. GIS mapping layers were created of wetlands as well as other natural resources for use by the project team in developing alternatives. CRI coordinated with natural resource agencies and regulators regarding existing conditions and potential impacts and led a multi-agency field review of the wetlands/waterways and other pertinent resource issues. CRI worked with project engineers to generate impact calculations, provided QA/QC for the calculations and summarized them by alternative. CRI compiled all natural resource data into a comprehensive Natural Environmental Technical Report (NETR) and Draft Environmental Impact Statement (DEIS). CRI conducted historical research on natural resource trends within the study area and authored the natural resources portion of the Indirect and Cumulative Effects (ICE) document.
In later planning stages, CRI obtained a Jurisdictional Determination from the USACE for the project. CRI also prepared the Final Environmental Impact Statement (FEIS) and updated the NETR for the water resources section to reflect current project designs. CRI calculated the required afforestation/reforestation acreage using the Forest Conservation Worksheet to determine how much acreage would be required for project related impacts. CRI developed a forest mitigation package through consultations with MDNR and MTA that included a suite of forest mitigation options. CRI is in the process of developing a mitigation package for impacts to wetlands and streams by including several types of mitigation such as stormwater best management practices, reforestation, wetland mitigation, stream restoration, and fish blockage removal. CRI is conducting field reviews with the U.S. Army Corps of Engineers and the Maryland Department of the Environment to get concurrence on the proposed mitigation package. CRI is also coordinating with Prince George’s and Montgomery County M-NCPPC regarding mitigation opportunities.
