This project is a public-private partnership between the City of Bloomingdale, The Savannah Economic Development Authority, and several large landowners/developers. The project provides water and sewer infrastructure for development of approximately 1800-acres of undeveloped property.  The project includes the installation 13,000 LF of 16” waterline, 13,500 LF of force main, 3850 LF of horizontal directional drills, a 313 GPM regional lift station, a water booster pump station, and a 400,000-gallon elevated water storage tank.

A master planned multi-use development for the city of Richmond Hill this project consists of commercial, institutional, multifamily, and single family uses.  The development of the property included a half mile spine road connecting Brisbon Road to S.R. 144, a 12-inch water main extension, a 335 GPM sanitary sewer lift station, and 6-inch force main.  The roadway portion of the project was critical to the City to provide an alternative route to Brisbon Road from SR 144 to reduce traffic congestion at the Brisbon/144 intersection.  Additionally, the water and sewer backbone infrastructure was needed to energize the civic space, passive park, commercial, and residential components of the master planned development.  CCI also assisted with the overall master plan for the commercial, single family, and City owned 51-acre portion of the development to be utilized as a passive park, amphitheater, civic building, future library, and event space.

The City of Bloomingdale was required to relocate existing water and sewer utilities that were located with in the proposed right of way of the extension of Jimmy DeLoach Parkway from US Highway 80 to I-16.  Coleman Company provided surveying and design services for the relocation of waterlines and force mains at the new US Highway 80 interchange and the relocation of Osteen Road.  Additional casings were designed under US Highway 80 to accommodate future development and expansion of the City’s system.  All utilities were relocated while maintaining existing  service to City customers.

Coleman Blvd. is a 0.85-mile , 4-lane roadway locate in the SPA Industrial Park.  The roadway spans across corporate limits of the city of Pooler and the City of Savannah.  The southern terminus of the road is at US Highway 80 with a multi-lane at-grade signalized intersection under GDOT jurisdiction.  Geotechnical evaluations of the existing 2-lane road indicated that the pavement was not adequate to support the anticipated level of truck traffic planned to access several large industrial developments under construction along the roadway. Coleman Company led a team that evaluated future traffic volumes and designed new pavement and drainage systems for the improved roadway.  A combination of new full depth pavement and milling with overlay was specified for the widened roadway.  Stormwater will be managed with curb and gutter and curb inlets.  The drainage system was designed to avoid numer4ous conflicts with existing utility within the right of way. A new signalized intersection with guarded left-turn phasing at US Highway 80 was warranted and designed and permitted through Georgia DOT.

Coleman Company provided forensic studies for a partially complete roadway system.  The project involved the reconstruction of a 0.47-mile divided parkway bringing it up to public road standards in the City of Port Wentworth, GA.  A detailed geotechnical investigation was used to evaluate portions of a previously unapproved portion of roadway so that new overlays and full depth pavement replacement could be constructed where recommended.  Detailed subsurface investigations allowed existing utilities to be located within the project corridor so that additional new utilities could be constructed without interring with existing systems.  Drainage improvements were required for the entire length of the project so that the adjacent property could be adequately drained and the new pavement could be properly maintained. The road was striped in accordand with MUTCD standards.

This project involves the reconstruction of a short section of Saussy Road in Port Wentworth Georgia to public roadway standards as part of a large muti-family development located adjacent to the right of way.  Due to the poor condition of the existing road, a full depth replacement of the pavement and regrading of roadside swales is necessary.  A new access with deceleration lanes and tapers is being constructed on GA Highway 21 to GDOT standards.  Signage and pavement markings conform to MUTCD.  Traffic on Saussy Road is being maintained throughout construction.

Coleman Company designed a new signalized intersection at US Highway 80 and the widening and resurfacing of a short section of Sangrena Road in Pooler, Georgia.  The improvements were necessary to accommodate increased traffic volumes due to commercial and residential development adjacent to the roadway and to improve the overall level of service of the intersection. The improvements included deceleration lanes on US Highway 80, new mast arm signals and controls with guarded left turn movements in each direction, sidewalks, and pedestrian facilities.  Signing and striping of the intersection conforms with GDOT and MUTCD requirements.  The signal warrant analysis and the construction plans were approved and permitted through Georgia Department of Transportation District 5 and the City of Pooler.

A master planned multi-use development for the City of Richmond Hill this project consists of commercial, institutional, multifamily, and single family uses.  The development of the property included a 0.6-mile spine road connecting Brisbon Road to S.R. 144, a 12-inch water main extension, a 335 GPM sanitary sewer lift station, and 6-inch force main.  The roadway portion of the project was critical to the City to provide an alternative route to Brisbon Road from SR 144 to reduce traffic congestion at the Brisbon/144 intersection.  The project included advanced coordination with GDOT for the widening of GA SR 144.

The Perry Street Utility Relocation Project involved relocating and upsizing existing City of Savannah water and sewer mains in a highly congested area of the city’s Historic District. Detailed Subsurface Utility Engineering allowed for the design and construction of new water and sewer lines in close coordination with numerous existing underground utilities and adjacent landowners.  The project included the design and permitting of a temporary sanitary sewer bypass system as well as stabilization of an existing 48” brick storm sewer.  The construction was accomplished while maintaining traffic on a portion of each of the existing roadways impacted by the work.

Coleman Company designed the reconstruction of Pipe Makers Canal for the City of Pooler, GA.  The project included the design of a 16-acre flood plain mitigation area adjacent to the canal and the reconstruction of a 14,000 LF section of the canal west of I-95. CCI evaluated the hydraulic impacts of proposed ballfields and the regrading of the mitigation shelf located on an adjacent property.  Along with the preparation of a No-Rise certification, a request for a Conditional Letter of Map Revision was submitted to FEMA upon completion of construction.

Coleman Company provided surveying, utility design, and construction phase services to Bryan County, Georgia for a new 8” well, a hydropneumatic tank, a new regional lift station, and 8” force main. The project allowed Bryan County to address the infrastructure needs of its rapidly growing population base.
