LTC 247-2017 Installation of Monitoring Wells - Marjorie Stoneman Douglas ParkMIAMIBEACH OFFICE OF THE CITY MANAGER NO. LTC # 247-2017 LETTER TO COMMISSION TO: Mayor Philip Levine and Members of he City Co. mission FROM: Jimmy L. Morales, City Manager DATE: May 10, 2017 SUBJECT: INSTALLATION OF MONITORING ` ELLS — Marjory Stoneman Douglas Park As part of the overall flood mitigation program, the City has contracted with AECOM, through the Public Works Department, to install groundwater monitoring wells. The wells, to be located across the City, will provide a better understanding of our hydrogeology and its direct relationship with flooding and sea level rise. Three wells have been proposed at Marjory Stoneman Douglas Park. The work will consist of installing three groundwater monitoring wells at different depth intervals from May 8th to May 19th. A drill rig will be used to install the wells. The site will be restored when the work is complete. Water and sediment produced from drilling activities will be adequately managed by following NPDES standards. At ground level, concrete pads will be poured around the wells to complete them. An automated measuring system will then be installed to monitor groundwater properties on a permanent basis. Work hours will be from 8:00 a.m. to 6:00 p.m., and extended hours are subject to City approval. The above work schedules are contingent on weather and may change due to unforeseen circumstances. Please see attached project advisory issued by the Public Works Department. Should you have additional questions regarding the installation of monitoring wells, please contact Carlos Tamayo at (786) 910-1452.
