@�Zg CRAIG A. SMITH & ASSOCIATES A SMART -INFRASTRUCTURE COMPANY April 2, 2026 (Revised April 9, 2026) Mr. Stan Morris, City Manager Sunny Isles Beach Government Center 18070 Collins Avenue Sunny Isles Beach, FL 33160 Via email to Ms. Susan Simpson, Deputy City Manager (ssimpson(c-sibfl.net) RE: Central Island Area Stormwater Improvements and Stormwater Pump Station Project CAS Project No. 21-2201 Amendment No. 6 to CAS Scope Dear Mr. Morris; Craig A. Smith & Associates (CAS) has provided professional engineering services (civil and electrical) for the design of two regional stormwater pump stations and new drainage system to provide flood relief for the Central Island Area of the City. We also provided a redesign that entailed 10 smaller pump stations that were to be incorporated into the existing drainage system and they were to pump into the existing drainage wells. The latter effort was intended to allow for a less costly project. However, maintenance records of a few drainage wells showed reduced discharge capacities and that some wells have not been re -tested to date. As such, current City staff and CAS met with a well drilling company (hydrogeologists) to consider an evaluation of all the wells' (10) performance and/or to restore well capacities that have been diminished. Discussions ensued in that well capacities overtime are reduced which can hinder pump operations and there may be the possibility that a well's capacity cannot be restored requiring the installation of a new well and an extension of a pump station's force main which can lead to field conflicts with existing utilities. Note that the operation of the original pump station design will not be hindered by the capacities of or lack thereof of the existing wells. As such, we concluded that the original design is a better long term option for the area. As such, the smaller 10 pump station approach has a shorter (perhaps a hindered) lifespan that is difficult to project due to well capacity uncertainty which may require the installation of a new well every 5-10 years at a cost in the $75K-$100k range plus plugging and abandoning the existing well. The original project will have an expected life span of at least 25 years if not more with routine maintenance independent of diminishing well capacities over time. In addition, maintenance of two stormwater pumping stations is easier to manage than the maintenance of 10 stations. CAS services for the following tasks will be needed. MDC-RER Class II Permitting: original application was deactivated and permit fees were returned to the City due to the redesign.
