Consent Item <br />Indian River County, Florida <br />Department of Utility Services <br />Board Memorandum <br />Date: February 2, 2024 <br />To: Indian River County Board of County Commissioners <br />Through: John A. Titkanich, Jr., County Administrator <br />Sean C. Lieske, Director of Utility Services <br />From: Howard G. Richards, PE, Manager - Capital Projects <br />Prepared by: Robert J. Tobar, EI, Utility Design Engineer <br />Subject: Amendment No. 1 to Work Order No. 5 to Masteller & Moler, Inc. for <br />Spoonbill Marsh River Intake Station Access Road & Electric Power <br />IRCDUS Project ID 12.24.501 <br />Background: <br />Spoonbill Marsh is a 69 -acre, man-made wetland operated by Indian River County within an easement on <br />lands owned by Grand Harbor North Lands, LLC. It is located just east of the US Highway 1 and 53`d Street <br />intersection. Spoonbill Marsh filters brine solution, a salt -heavy byproduct from the County's North Water <br />Treatment plant. This demineralized by-product is filtered through palms and mangroves, cleaning the brine <br />before it enters the Indian River Lagoon. Water from the Indian River Lagoon is pumped into the Spoonbill <br />Marsh wetland system by a pump station located on the property. <br />In October 2023, the electrical conduit supplying power to Spoonbill Marsh's pump station failed. As a result, <br />the pump station has been relying on power from a generator. Indian River County Department of Utility <br />Services (IRCDUS) is undertaking a project to replace the electric power cable to restore permanent power to <br />the pump station. IRCDUS also seeks to raise the access roadway to the pump station to provide more <br />stabilization and reduce the likelihood of wetland impacts, while incorporating the new electric power cable <br />for construction cost savings. <br />On November 30, 2023, Work Order (WO) No. 5 based on time and materials (T&M) was executed, <br />authorizing Masteller & Moler (M&M) to perform engineering services to immediately commence initial <br />design activities. Work authorized under WO No. S is nearing completion, and IRCDUS seeks to authorize <br />M&M to complete civil engineering and related subconsultant services associated with design and permitting <br />of the proposed access roadway and electric power. <br />Analysis: <br />Upon request by IRCDUS staff, M&M prepared the attached Amendment No. 1 to WO No. 5 to provide <br />engineering, design, environmental, and construction phase services for the Spoonbill Marsh River Intake <br />161 <br />
