Union City: SR 138 Project
Service Details
Surveying
Route surveying performed along SR 138 (6000 l.f.) in preparation of Base Map for design of roadway and pedestrian improvement project. SEI obtained right of way plans, deeds, plats and other pertinent information for project planning and for future right of way resolution. SEI utilized survey grade GPS units to establish survey control throughout each route for Vertical (MSL) and horizontal control. These control points were confirmed for accuracy by running a level loop on each route. A robotic total station and total station were utilized to gather the data required for the Base Map. These include; topography, creeks, streams or ditches, storm water and sanitary sewer pipes and associated structures, curb, gutter, pavement, striping, traffic control devices, all above ground visible utilities, property corners, right of way markers and any unusual features. Information gathered was then processed and verified for accuracy, imported into CAD format.
Analysis on the right of way was performed and resolved. The Base Map was then provided in Microstation format for our Transportation Department to begin conceptual design.
Transportation Engineering
The purpose of this State and Federally funded project was to add, improve and enhance the pedestrian facilities along these corridors. All of SEI’s disciplines were involved in the performance of this contract. Included in these improvements was the upgrade of many intersections and signal modifications for ADA compliance, such as Roosevelt Highway at Lower Dixie Lake Road, Raymond Drive and Gresham Street. A speed reduction study was also performed for the SR 138 corridor to lower the existing 55 mph speed limit to 45 mph to allow for curb and sidewalk. A sloped concrete abutment was designed to allow for an 8’ wide sidewalk/golfcart path across the 75 lf section on Lester Road where it crosses a roadway culvert over Broadnax Creek.
Environmental Services
As a necessary function of the planning, design and engineering of this project, SEI also performed the required environmental screening. This project is a State funded TE project subject to regulations outlined in the National Environmental Policy Act (“NEPA”) and/or Georgia Environmental Policy Act (“GEPA”). It was found that no archaeological or historical features will be affected by any portion of the project therefore a Programmatic Categorical Exclusion (PCE) has been applied for. SEI also performed a JD and provided regulatory coordination with the U.S. Army Corps of Engineers (“USACE”) to identify and impacts to waters of the U.S. Similarly, SEI also coordinated with the Georgia Environmental Protection Division (“EPD”) to identify and impacts to stream buffers associated with waters of the State.
