Site work for a water / sewer project in Biloxi, Mississippi. Completed plans call for site work for a water / sewer project.

The MDMR is seeking bids from qualified and experienced contractors to demonstrate how nature-based stormwater management can reduce flooding by directing stormwater through vegetation to infiltrate soils with a high drainage capacity rather than to underground pipes, such as is the conventional approach. The scope of work to be performed and the deliverables required under the contract are also set forth herein.

The soil will be sloped to the center of each rain garden and planted with plants or trees suitable for these conditions. Stormwater will be directed to enter the five rain gardens via curb gaps that are detailed in the construction drawings. A 170' linear foot bioretention swale will be constructed along Martin Luther King Boulevard by removing compacted soil to a 44" depth and replacing with a high-drainage-capacity soil and drainage rock as specified in the plans. The soil will be sloped to the center of each bioretention cell and planted with plants or trees suitable for these conditions according to the drawings. Stormwater will be directed to enter the linear bioretention cells via three 4'-6" curb inlets that narrow to 2'-6" as they pass under formed concrete sidewalk/inlet structures. A series of containing walls and an earthen berm constrain the in-flow, while the entire system is connected subsurface. A series of 4" diameter standpipes will direct any overflow into an existing 18" RCP to prevent stormwater from flowing back out into the roadway. The Contractor will be responsible for municipal permitting and procurement of materials, subcontractors, and equipment.
