Henderson Center Improvements 2021
This project, in general, addressed replacing the water main, sewer main, and paving on Henderson Street from F Street to Fairfield Street. This project was completed November 2021.
Pedestrian Crossing Improvements 2020
Highway Safety Grant Funded Project. The project included pedestrian and vehicle improvements at 35 intersection locations throughout the City, including crosswalk markings, rapid-flashing beacons, curb extensions, flashing beacons at stop signs, and audible pedestrian signals.
Cross Town Interceptor Cathodic Protection Maintenance 2019
The Cross Town Interceptor (CTI) is the City's primary force main to the Elk River Wastewater Treatment Plant (WWTP). The cathodic protection (CP) system slows the erosion of the pipe material to ensure the longevity of the pipeline and reduces the possibility of a leak. This project replaced key components of the system that were close to the end of their expected life.
Pump Station Motor Control Center (MCC) Installation and Commissioning 2019
Three large Pump Stations move the sewage from the main collection locations in the city through the Cross Town Interceptor to the WWTP. The equipment that runs these stations was in need of replacement to allow for more efficient and controllable operation.
Broadway and Vigo Signalization 2019
This traffic signal installation at the intersection of Broadway and Vigo Streets provides improved access to future developments on Vigo Street. Improvements, in addition to the traffic signal, included installing new pavement markings, new street lighting, as well as new pedestrian curb ramps. The project was administered through the City and coordinated through Caltrans which took ownership of the signal at completion. The total cost of the construction for this project was $370,897.
Bus Stop Improvements 2019
The project was designed and constructed to improve bus stops at various locations throughout the City. Improvements included replacing sidewalks to provide ADA access, solar lighting retrofits of existing shelters, and installing new bus shelters. The total construction amount totaled to $148,454.30. The project was funded by Public Transportation Modernization Improvement Service Account (PTMISEA) grant funds and required no funds from the City.
Regulatory and Warning Sign Upgrade HSIPL- 5017(045) 2019
The City was awarded a Highway Safety Improvement Program (HSIP) Grant for replacing regulatory and warning signs throughout the City - stop signs, speed limit signs, and the like. The purpose of the project was to inventory all regulatory and warning signs within City limits and replace those signs that were faded, damaged, or failed the retro-reflectivity test. Over 1,700 signs were replaced as a result of this project. The total cost of construction for this project was $249,343.10.
Pavement Rehabilitation 2021
State Transportation Program / Gas Tax Funding. Now in its final design phase, this project broke ground in spring. The project is addressing portions of five streets throughout the City of Eureka. These include Felt Street between Del Norte and Hawthorn Streets; Hawthorn Street between Broadway and Felt Streets; Koster Street between Del Norte and Washington Streets; Highland Avenue between Glenn and Broadway Streets; and 14th Street between West Avenue and Broadway.
As of September 1st, 2021, supplementary funding has been released for additional street paving, which includes the following: Commercial Street between 5th Street and north of Waterfront Drive; W Washington Street between Broadway and Waterfront Drive; E Street between Harris Street and Oak Street; Spring Street between Harris Street and Henderson Street; and F Street between Harris Street and Henderson Street.
Improvements include removing and replacing asphalt roadway sections, adding new layers of asphalt pavement as well as installing thermoplastic markings, truncated domes, new curb, and sidewalk and curb ramps in some locations. This project is expected to be completed by October of 2021.
4th Street Underground
All utilities on 4th Street from Y Street to Little 4th are being installed underground in a joint trench with PG&E, AT&T, and Suddenlink. Underground utilities reduce outages because buried lines are not susceptible to damage from high winds or falling trees. Underground utilities also look better aesthetically and generate a positive economic impact by reducing outage-caused downtime for local businesses.
Elk River Waste Water Treatment Plant Cogeneration System Upgrade
This project consists of removing existing engine generators and associated heat recovery systems: Installation of one new engine generator (cogeneration system) with new waste heat recovery and waste heat removal equipment; one new hot water boiler; digester gas cleaning system; and all electrical, utilities, and piping systems for the above listed equipment.
Infiltration and Inflow Projects
Infiltration and Inflow (I/I) is a large contributor to the sewer flows that end up at the WWTP in the wet season. This is due to older pipes that have developed leaks due to settling, earthquakes, root intrusion, and various other means allowing groundwater into the sewer collection system. Additionally, private properties often contribute by adding rainwater from roof drains, groundwater from basements and crawl spaces, or broken laterals allowing water into the sewer system. Large basin-wide projects are being performed to try to reduce I/I in the public right-of-way.
