Background and Analysis:
The Building Resilient Infrastructure and Communities grant program funds cost effective mitigation projects that are designed to increase resilience and public safety, reduce injuries and loss of life, and reduce damage and destruction to property, critical services, facilities, and infrastructure. It is a cost-share grant, 75 percent federal funds and 25 percent local funds.
The Percival Creek Utility Bridge was severely damaged on February 7, 2020, when a tree fell and struck the middle span breaking the existing sewer and water mains that are attached to the underside of the bridge. At the time, approximately 30,000 gallons of untreated sewage entered Percival Creek, Capitol Lake and Budd Inlet. Although the bridge and sewer main have been brought back to pre-disaster function, the bridge continues to be susceptible to storms, landslides, and earthquakes. The Wastewater Utility is proposing to mitigate this risk by using horizontal directional drilling to reroute the sewer main under Percival Creek. Following relocation of the water main and private utilities, the Percival Creek Utility Bridge would be removed.
The existing 10-inch diameter sewer main which currently crosses Percival Creek via the Percival Creek Utility Bridge connects Evergreen Park Court SW to an existing LOTT Clean Water Alliance interceptor pipeline located adjacent to Percival Creek and the nearby railroad. It is a critical connection within the City’s sewer infrastructure. The sewer main is the only outlet for the sanitary sewer system for the area known as Courthouse Hill. Approximately 765 residential accounts and 42 commercial accounts, including the Thurston County Courthouse, are provided service by this sewer main.
The “Resolution Designating Applicant Agent” must be submitted with the completed FEMA Hazard Mitigation Grant Program Sub-Application for the Percival Creek Utility Bridge Sewer Reroute Project.
The grant sub-application is due November 8, 2021.
Neighborhood/Community Interests (if known):
The goal of the proposed project is to mitigate the loss of an essential service (sanitary sewer service) to residential and business customers that would result from a storm, landslide or earthquake causing damage to the Percival Creek Utility Bridge. With the proposed rerouting of the sewer main under Percival Creek using horizonal directional drilling the adverse impacts from a storm, landslide or earthquake will be minimized.
Options:
1. Approve the Resolution authorizing the Wastewater Utility to apply for a Building Resilient Infrastructure and Communities grant and sign the required Resolution Designating Applicant Agent, as well as authorize the City Manager to sign the grant, if awarded. This allows staff to apply for the grant by the deadline and, if funded, implement the project in 2023-2025.
2. Decline the request to submit the grant application and sign the required Resolution Designating Applicant Agent. Staff would not apply for grant funding, instead an alternative source of funding, such as wastewater utility rates, will be required for the project.
Financial Impact:
The total project cost is estimated at $4,725,000. The maximum federal share is 75 percent of the total eligible costs. The minimum non‐federal cost share is 25 percent. The City’s 25 percent match will be covered by the Wastewater Utility.
