Aeenda Item Title: Sebastian Stormwater Master Plan Update by Arcadis U.S., Inc.
Recommendation: Staff recommends Council accept the Stormwater Master Plan created by
Arcadis U.S., Inc., and provide future direction in relation to its findings
Ilackeround: In October 2020 the City of Sebastian began the Request for Qualifications
process to find Stormwater Master Planning & Professional Engineering Services through RFQ#20-05.
Through the evaluation committee Arcadis U.S., Inc. was chosen to complete the City of Sebastian's
Stormwater Master Plan Update. In April of 2021 a Continuing Services Agreement, CSA#01, with Arcadis
U.S., Inc., was approved formalizing the services and deliverables of the master plan update. Arcadis U.S.,
Inc., completed an extensive survey of the City's existing stormwater system in order to create an H&H or
hydrologic and hydraulic model of the City's stormwater drainage system and evaluate its functionality. In
addition to modeling the system's capacity and limitations, Arcadis U.S., Inc. evaluated the existing
Stormwater Division within the City in relation to its processes, protocols, staffing, funding, and maintenance
activities and frequency to give an overall understanding of the system as well as the current maintenance it
receives. From analyzing the existing conditions as well as maintenance, Arcadis U,S., Inc., has compiled
within this update recommendations regarding City staffing, budgeting, maintenance operations, and a revised
capital improvement plan in order to meet the minimum level of service for the stormwater conveyance
system. The Stormwater Master Plan Update provides a wealth of information related to Stormwater within
the City of Sebastian that is helpful to not only City staff for future planning and resiliency but also residents
and local businesses regarding regulatory restrictions, design conditions of the City's system, grant funding
opportunities, climate challenges, and more.
City Staff is looking to Council for acceptance of the Stormwater Master Plan Update provided as well as
direction as to next steps in response to findings of the report.
