Stormwater Management Facilities
Henry County Medical Center, Paris, Tennessee
L.I. Smith analyzed the 75-acre drainage basin upstream of the Henry County Medical Center, in order to design stormwater conveyance and detention facilities capable of reducing peak runoff rates to pre-development rates for not only the HCMC expansion plans but for future developments on other properties in the drainage area. Additionally, the facilities were designed and evaluated for the maximum achievable benefit to downstream properties.
Bailey Fork Tributary Two Flood Study
Jim Adams Commercial Development, Paris, Tennessee
L.I. Smith & Associates, Inc. surveyed 26 cross sections along 6,500 feet of the upper reaches of the Bailey Fork Tributary Two in Paris, and modeled the stream sections using HEC-RAS to more accurately define the 100-year floodplain and floodway, in accordance with FEMA requirements.
Private landowners had straightened this section of the stream and a new city street had been constructed about 15 years prior. The channel had experienced down cutting due to the change in the hydraulics associated with the re-alignment, and the floodplain was determined to be much less restrictive on adjoining properties than was previously mapped. This information was forwarded to the local code officers and to FEMA for upgrading the published floodplain information.
Wetlands Delineation and Surveys
Teague Transports, Jackson, Tennessee
L.I. Smith & Associates, Inc. was the prime consultant to delineate, mark, and survey the perimeter of approximately 48 acres of wetlands as part of a larger project to develop a sand extraction facility on the privately owned property of Teague Transports in Jackson, Madison County, Tennessee. This project was located along the Middle Fork of the Forked Deer River.
GPS control points were established for use by conventional survey methods to locate and mark the wetland's perimeter, and to determine the property boundary for the total parcel of 108 acres.
The flood elevations were determined to evaluate the impact of any levels or ponds might have on flooding the area, and the effect to the total floodplain.
Valleywood Drainage Improvement
City of Paris, Tennessee
L.I. Smith & Associates has the engineering and surveying capability to size storm sewers and open channel flow requirements. For this project, L.I. Smith & Associates, Inc. was required to design and survey a drainage improvement project for Valleywood Drive in Paris, Tennessee. The project consisted of determining runoff for 25, 50, and 100 years, storm and sizing inlet, and culvert to accommodate that amount of runoff. It was determined to use a 50-year storm as the design criteria.
