About this file
This document is a 100% design plan set for the Great Swamp Effluent Management System Access Road Low Water Crossings project, prepared for the Beaufort-Jasper Water & Sewer Authority (BJWSA) in Hardeeville, South Carolina. The project involves the construction of three armored low water road crossings over an existing 24-inch diameter effluent pipeline as part of the Great Swamp Effluent Management System expansion. The plans were prepared by Wetland Solutions, Inc. (certification of authorization number 4556) and are located in Jasper County near the intersection of Independence Boulevard and Argent Boulevard. The design includes detailed plans and profiles for three distinct crossing areas (Areas 1, 2, and 3), each with specifications for FLEXAMAT 10 NW armoring materials, crushed stone base courses, concrete encasement over the pipeline, and grading to accommodate existing site conditions. The plans are digitally signed and sealed by Christopher H. Keller, South Carolina P.E. License No. 29477 (civil engineer) and John V. Sobczek, South Carolina P.E. License No. 33262 (structural engineer), with a project date of November 2025 and structural seal date of October 2025.
The design specifications include minimum 10-inch crushed stone base layers (reduced to 7.5 inches over concrete-encased pipe), top-of-crossing elevations ranging from 7.9 to 8.1 feet, and 20:1 maximum slope transitions to tie into existing grades. All work within wetland areas must be performed on temporary mats, and contractors are required to field-verify dimensions and pipeline locations prior to ordering materials. The plans reference South Carolina State Plane Coordinate System (NAD83-2011) for horizontal positioning and NAVD88 (GEOID 18) for vertical elevations. Coordination with the BJWSA inspector and project manager is mandatory. Construction notes specify that an engineer or manufacturer's representative must be onsite for installation start, all subgrade surfaces must be smooth and free of debris, and FLEXAMAT rolls can be manufactured up to 16 feet wide and 100 feet long. The document includes detailed reinforcement specifications, concrete requirements (minimum 4,000 PSI compressive strength), and standard hook development lengths for rebar in accordance with ACI 318-14 standards and the 2021 South Carolina Building Code.
