Project Details

CRI provided a range of forestry and geospatial services for a new railroad corridor access road in Arlington County, Virginia.

The new access road was proposed between the railroad track and Long Bridge Park to support CSXT railroad maintenance activities.  The access road would extend approximately 2,765 feet along existing tracks and includes a driveway into the Long Bridge Park.  CRI performed a forest stand characterization of all forest stands within and around the project area to document successional stage, dominant and co-dominant species, size classes based on ranges of diameter at breast height (DBH), common understory and herbaceous species, percent canopy closure, prevalence of downed woody debris, and basal area. CRI also identified the species, size, and condition of all trees measuring 3 inch (DBH) or greater.  CRI used a handheld Trimble Global Positioning Unit (GPS) to survey the locations of all trees.

Once field work was complete, CRI prepared a Landscape Conservation Plan (LCP) map according to County requirements.  Among other features, the LCP map included any 100-year floodplains, streams, delineated wetlands, required wetland and stream buffers, Resource Protection Areas, steep slopes, forest stands, topographic contours, soils data, identified trees, and a site vicinity map.  CRI developed a planting plan to accompany the LCP, with mapping that detailed proposed planting locations, recommended species, and planting quantities for reforestation following construction. CRI also assisted with preparing the Re-Vegetation/Forestry Management Plan component of the Water Quality Impact Analysis that accompanied the construction submittal.

The LCP map was submitted to the Arlington County Department of Parks and Recreation for review and approval.  Comments and revisions were completed as required, and the resubmitted plans were approved.  All work related to the LCP was led by one of CRI’s Certified Arborists.
