The Lafayette Street corridor is one of the oldest roads in Leon County and the State. The corridor has long been regarded as an integral part of the Meyers Park area, the Smoky Hollow neighborhood and local business community. It once served as the primary access to the original State Capitol Building.  In an effort to improve the drainage on Lafayette Street, Leon County turned to Genesis  to determine the stormwater infrastructure needs for the corridor. As one of the oldest concrete roadways in Tallahassee, the existing pavement and curbing was experiencing extensive cracking and settlement. Over the years, several layers of asphalt resurfacing had been applied but experienced severe reflective cracking from the deteriorating underlying concrete pavement.  The existing stormwater system within the corridor was in disrepair and inadequate for the amount of flows being conveyed to the roadway. There was no existing stormwater treatment facility. Moderate rainfall events produced flooding at the low (west) end of the project.

The County determined that the roadway needed to be reconstructed and the existing pavement, curb and sidewalk removed and replaced.  Genesis provided a hydrological assessment of the Lafayette Street corridor to evaluate runoff from adjacent neighborhoods and businesses.  A complete underground storm sewer system was designed, including intercepting structures and piping, to accommodate peak rainstorm events with minimal flooding downstream.   Genesis developed roadway and drainage construction plans which included new six- to eight- feet-wide ADA compatible sidewalks for pedestrian usage. 

Services provided by Genesis included surveying, design, utility coordination, public involvement, permitting and construction assistance.  Due to the narrow corridor width, an elaborate series of detours was developed to enable sections of the roadway to be closed to through traffic during construction.  Special detour signage was required to divert traffic to alternate routes.  Extensive collaboration with property owners and City Transit staff was required to establish optimal construction times and minimize impacts to local traffic.
