__________________________________________________________________
BACKGROUND
Indian River County Department of Utility Services (IRCDUS) provides water, wastewater, and reuse services to major portions of Indian River County (IRC), including the City of Sebastian and Town of Orchid. IRCDUS’ water system is the largest in the County with a combined annual average Consumptive Use Permit (CUP) of 12.838 million gallons per day (MGD) that serves a population of over 110,000 across an urban service area (USA) of 96.44 square miles.
On October 23, 2018, America's Water Infrastructure Act (AWIA) was signed into law. Section 2013 of AWIA amended the Safe Drinking Water Act (SDWA), to require community water systems (CWSs) serving more than 3,300 people to develop or update risk and resilience assessments (RRAs) and emergency response plans (ERPs). CWS’ were required to self-certify, with the U.S. Environmental Protection Agency (US EPA), the completion of their AWIA compliant RRAs and ERPs by specified deadlines based on the population served. Thereafter, CWS’ must review, revise where applicable, and recertify their RRAs and ERPs to US EPA every five years from the original deadlines specified in the law.
To meet compliance with requirements of the AWIA five-year review while ensuring that emerging threats to the water system are addressed, the Indian River County Board of County Commissioners (BCC) on September 10, 2024, approved Work Order No.1 (WO 1) to Arcadis U.S., Inc. (Arcadis) under its continuing contract agreement with the County dated May 2, 2023, in the amount of $456,330.10. Under WO 1, Arcadis is providing professional engineering and technical services to prepare AWWA compliant RRA and ERP Updates (IRCDUS Project ID 00.24.518).
IRCDUS certified the completion of its RRA and ERP updates prepared by Arcadis, to the United States Environmental Protection Agency (US EPA) on March 28, 2025 and September 19, 2025 respectively.
ANALYSIS
As a result of the work performed under WO 1, IRCDUS requested Arcadis to provide additional services to prepare for and present to the BCC, which is described in the attached Amendment 1 to WO 1 Scope of Services. Arcadis proposed fee for Amendment 1 to provide the additional services is $28,506.08. Upon approval of Amendment 1 by the BCC, the total approved budget for WO 1 will increase to $484,836.18.
BUDGETARY IMPACT
Funds, in the amount of $28,506.08, for this project are budgeted and available in the Utilities/Gen & Eng/Other Prof /Water System AWIA Updates account, number 47123536-033190-24518, in the Utilities operating fund. The Utilities operating fund budget is derived from water and sewer revenues.
