County of Hawaii Multi -Hazard Mitigation Plan Executive Summary Action HC1—Microwave Network Upgrade. This project involves the hardening of fhe County's radio Medwm " High communications system through replacement of the following systems: microwave system, direct current ; (DC) power system, photovoltaic energy systems,_and tower refurbishment. _ Action HC2=Public Safety Building Flood MiUgation and Electrical Upgrade. This project will eliminate Medium High flooding that endangers the entire electrical system at the Public Safety complex and causes damage in other areas. The electrical system will be upgraded to prevent failure. Action HC3—IT Data Center. install a SmarfMod 12x45 with a 11x34 u6Tity skit to support the data center Medium High that supports critical services for the County currently housed at the CM Defense building (924 Ululani SL, Hito) and the IT Department bu➢ding (25 Aupuni St, Hilo) - Action HC4--Wafluku Bridge #1 and Waianuenue Avenue Bridge Hardening. Wailuku Bridge #1 over _ Medium High Wailuku River on Wainaku Street is an essential part of the traffic network in the area as it serves as a detour or important alternate route for Highway 19, The existing 129-foot, 2 span concrete bridge was built in 1919 and is not in compliance with today's engineering design standards, specifically in regard to resisting seismi.0brces. Action HC5--Generators for Wastewater Treatment Facilities. Install eight stationary generators to service Medium High the Hilo Wastewater Treatment Plant (WWTP); Kula1mano WWTP; PApalkou WWTP; Wa➢uku Sewer Pump Station (SPS); Pauka'a SPS; Wailoa SPS; Onekaakaha SPS; and Kolea SPS during severe weather events. These facilities experience significant power outages. The Installation of generators will mitigate outages during these events. Action HCS—Emergency Power Transfer Switching Capability for Critical Water Infrastructure. The Medium High hardening of the Parker#1, Parker#2, LAIAmilo B, Lalamilo C, Honoka'a, Makapala, Wal`aha, Kahaluu, Queen Lili'uokalani Trust, Pi ihonua #1, Pi1honua #3A and 'Ola'a #3 potable water producing facilities through the purchase and Installation of transfer switches and supporting infrastructure (generator tap boxes, junction boxes, conduit, wire, supports, etc.) will allow the County of Hawaii Department of Water Supply to better protect the health and welfare of the public. Action HC7 Watkoloa Reservoir No.1—Dam Failure Retrofit. The project requires the improvements to Medium Hgh address the stability of the embankments as well as the waterproofing of the reservoir itself. The embankments are being improved by widening the base of the embankment and increasing the overall strength supporting the reservoir walls. An underdrain at the toe of the embankment is also being installed to direct groundwater away from the embankment to minimize the chances of liquefaction. Also, waterproofing the reservoir will be accomplished by installing a synthetic liner, which eliminates the possibility of leaks through the numerous cracks in the concrete panels lining Pe interior of the reservoir. Action HC8—kcGIS Data Management, Collection and Tracking. Create an Information/data management Medium High system to provide actionable information to the planning process during an incident and to capture data for Impact statistics and hazard analysis post4ricidenL Action HC9—Volcanic Risk Home Buyout Program. Develop and institute a home buyout program that Medium high targets eligible properties impacted by lava flows from volcanic eruptions. 1 Action HC14—Maintain NFIP Compliance. Continue to maintain good standing and compliance under the High Medium NFIP through implementation of floodplain management programs that, at a minimum, meet the NFIP requirements: • Enforce the flood damage prevention ordinance. t • Participate in floodplain Identification and mapping updates. Provide public assistancetinformation on floodplain requirements and impacts. - Action HC11—Maintain CRS Participation. Continue to maintain and enhance (where feasible) the County's High Low classification under the CRS program. Action HC12—Flood Hazard Needs Assessments. Perform needs assessment and riverine flood studies for Medium High Puna, North Kona, and South Kohala to Identify flood control projects and for Hamakua (to figure out what is the real risk associated with landsides). xxly TETRA TECH
