Attachment #4 WATERS OF THE US DELINEATION MAP_Riverwalk_2019-12-12.pdf

This is a Waters of the United States Delineation Map for the City of Hopewell, Virginia, prepared in November 2019 in support of the Hopewell Riverwalk construction project. The map delineates wetland and water features within the project area that spans approximately 6.45 acres. The delineation identifies four distinct wetland categories: Palustrine Forested (PFO) covering 1.70 acres, Riverine Unconsolidated Bottom (R1UB) covering 2.94 acres, Palustrine Shrub-Scrub (PSS) covering 0.14 acres, and Palustrine Emergent (PEM) covering 0.88 acres. The map also establishes mean high water (MHW) at 0.90 feet and mean low water (MLW) at -1.56 feet, indicating tidal fluctuation ranges relevant to the project site. The document includes the approximate Riverwalk alignment and references VGIN aerial imagery, NOAA, and FEMA data sources to support the delineation accuracy.

This technical documentation serves as a critical environmental baseline for the Riverwalk construction project, which aims to connect the existing Phase II terminus to the Hopewell City Marina. The delineation map is essential for environmental compliance and permitting purposes, as it identifies jurisdictional waters and wetlands subject to federal and state regulation. The detailed acreage breakdown and boundary mapping provide contractors and regulatory agencies with precise information necessary for project planning, design modifications, and mitigation strategies to address impacts to regulated waters and wetlands during construction.
