206 <br /> THURSDAY, DECEMBER 10, 1998 <br /> <br />streams of localities who were already dealing with their refuse in responsible and cost effective ways. City <br />Manager Earl B. Reynolds, Jr. referred to the efforts as flow control without calling it flow control. <br /> <br /> Council next received a presentation from Mr. Joyce and Ms. Jan McHargue, also of Joyce <br />Engineering, on current conditions and issues related to the Martinsville City Landfill. This presentation <br />began with a brief history of the landfill, which had begun operations in 1971. It was noted that the landfill <br />had been built over three streams which were currently piped beneath the fill areas, and that the staff of Joyce <br />Engineering, in concert with,City staff, had discussed several ways to mitigate and protect against the <br />possible failure of any of the existing pipes and circumstances related to such failure: · Ms. McHargue then <br />presented their ~rm's analysis of the piping system with regard to hydraulic capacity, and various pipe <br />failure scenarios under both existing conditions and with remedial measures in place. Three drainage areas <br />related to the three pipes in use were described, with varying degrees ofponding, flooding and impact to the <br />landfill. Remedial measures considered were then presented, including tunneling and placement of new <br />pipes, provisions for bleeding down trapped water following pipe failure, purchase of additional property to <br />avoid problems for adjacent landowners, installation of a supplemental pump system and a water level <br />monitoring system, and slope protection measures. Ms. McHargue concluded witha recommendation of <br />four remedial activities which could be implemented independently or in combination. These measures <br />included installation of bleed-down pipes, to be sleeved within the existing pipes; purchase of additional <br />property in areas where flooding might occur; installation of water level monitoring equipment to provide <br />early warning of pipe failure and flooding; and installation of a synthetic liner on the face of the land fill to. <br />provide slope protection from water intrusion beneath the landfill. <br /> <br /> Further discussion then occurred among Council Members, City staff and Joyce Engineering staff <br />regarding elements of the remediation presentation and cost estimates for some of the recommended work. <br /> <br /> <br />
