Tradeport West Way – Phase 1 Site Development Plan

This document comprises comprehensive construction design plans for the Tradeport West Way – Phase 1 project in Liberty County, Georgia, prepared by Thomas & Hutton for the Liberty County Development Authority. The project encompasses site development improvements including roadway construction, utility infrastructure installation (water and sewer systems), stormwater management, and erosion control measures across approximately 35 acres. The design plans document existing site conditions, proposed grading and drainage, cross-sections for Highway 17 improvements and the proposed Tradeport West Way roadway, water and sewer line layouts with profiles, paving specifications, and comprehensive erosion and sedimentation control plans across three construction phases (initial, intermediate, and final). The project site is located in Midway, Georgia, zoned for industrial use (I-1), with service provided by Liberty County utilities. Design revisions were completed on March 19, 2026, with the plans marked as a bid set not yet issued for construction.

The design includes detailed construction specifications addressing utility separation requirements (10-foot horizontal and 18-inch vertical clearance between water and sewer lines), sediment storage requirements totaling 2,345 cubic yards with 4,317 cubic yards provided across multiple sediment basins, stormwater outlet protection with riprap specifications, and three-phase erosion control implementation including silt fencing, inlet sediment traps, dust control, temporary and permanent seeding with specific monthly planting windows, and construction exit specifications. The professional engineer of record is Felipe Toledo, P.E., with GSWCC Level II certification number 0000095887 (expiration October 22, 2027). Sampling requirements are established at two storm water monitoring locations for turbidity analysis at 50 NTU per the warm water fisheries standard, with specific sampling protocols following NPDES permit GAR 100003 requirements and 40 CFR Part 136 methodology.
