ATTACHMENT A – BRIEF DESCRIPTION OF Project

Pierce County Planning & Public Works – Office of the County Engineer Division (County) solicits interest from consulting firms with expertise in Civil and Structural Engineering Design. This agreement will be for approximately two years in duration, beginning September 2026 and ending September 2028, with the option for the County to extend it for additional time and money if necessary.

The existing Chambers Creek Bridge #29202-A was built in 1946 and crosses over Chambers Creek on Chambers Creek Road West connecting the Town of Steilacoom and the City of University Place. The 65-foot long, 22-foot-wide bridge consists of four concrete-slab spans supported by twelve timber piles, with abutments reinforced by timber sheet piles. The existing facility has minimal shoulder widths, no pedestrian facilities and an FHWA Overall Condition Classification – Fair. The roadway classification for Chambers Creek Road is Secondary Arterial with a 2019 ADT of 7275.

The replacement of the Chambers Creek Bridge is an element of a larger effort to restore the Chambers Bay Estuary that involves the removal of the Chambers Creek dam, estuary bank protection measures including the transport of sediment above the bridge and dam, as well as riparian and marsh restoration. As part of a larger effort to restore the estuary, the bridge must be designed to future conditions following the removal of the Chambers Creek Dam, subject to tidal influence and differing hydrogeomorphology. The project area includes a salmonid bearing stream, wetlands, floodplains, geologic hazards, and possibly cultural resources.

This project will replace the functionally obsolete Chambers Creek Bridge and other associated work. This project will provide a constructability plan for relocation and reduction of impacts to utilities connected to, running under and within the vicinity of the existing bridge. Bridge replacement design will include relocation and protection of utility infrastructure that serves University Place, the Town of Steilacoom, and the City of Lakewood. It will also include pedestrian crossings and parking to improve safety and access to the adjacent Chambers Creek Canyon trail system. The bridge alignment and roadway reconfiguration must also allow for continued turning movements for a WB-40 semi-truck to enter the Chambers Creek Regional Wastewater Treatment Plant and the BNSF access road.

The County is initiating engineering design for County Road Project (CRP) 5938, the Chambers Creek Bridge Replacement Project. To support this effort, Pierce County is seeking an engineering firm to provide Preliminary and Final Design Engineering services for the project. This is anticipated to be a federally funded project and must adhere to the WSDOT Local Agency Guidelines. In 2023, Pierce County completed a Type, Size and Location (TS&L) study for the bridge replacement project which can be found here: Chambers Bay Estuary Restoration | Pierce County, WA - Official Website.

The major features of the project are as follows:

1) Roadway, parking lot and bicycle/pedestrian improvements related to the new bridge,

2) Demolition plan for the existing bridge,

3) Structural design for the proposed bridge and walls required for the bridge abutments and roadway approaches,

4) Stormwater collection and treatment facilities,

5) Pedestrian crossing enhancements and roadway illumination requirements for new pedestrian crossings and parking to improve access to the adjacent Chambers Creek Canyon trail system,

6) Utility design for the new bridge and temporary utility bypasses during construction, including preconstruction investigations and ongoing coordination with utility providers and jurisdictions during the design process,

7) Environmental permitting and mitigation,

8) Communication and engagement with tribes, interested parties and the community,

9) Determination of Right-of-Way needs and plan preparation, and

10) Coordination with teams working on the other stages of the larger estuary restoration project.

ATTACHMENT B – SCOPE OF WORK

The Preliminary and Final Design Engineering sought is for a full range of services and will build off work from the 2023 TS&L Study (KPFF). The objective of the scope of work will be to build from and advance the previously completed effort to complete preliminary and final engineering design, contract plans, special provisions and engineer’s estimate, in accordance with AASHTO LRFD Bridge Design Specifications, 10th Edition, WSDOT Bridge Design Manual (BDM), WSDOT Geotechnical Design Manual (GDM), WSDOT Hydraulic Manual, WSDOT Local Agency Guidelines (LAG), the Pierce County Stormwater Management and Site Development Manual (2026) and other applicable design standards. The services are expected to include, but are not limited to, the following:

1) Project management,

2) Coordination and collaboration with teams working on other stages of the larger estuary restoration project,

3) Civil and structural engineering design,

4) Mitigation, restoration, and/or enhancement design for shorelines, wetlands and fish and wildlife conservation areas,

5) Hydraulic design including supplementing the previously completed model/investigations and hydraulic design to account for future conditions following dam removal resulting in new geomorphology and tidal influence,

6) Applicable engineering studies and design reports,

7) Development of final contract plans, specifications and estimate (PSE) package for project advertisement,

8) Traffic engineering for channelization, illumination, signals and signing required for new pedestrian crossings and parking accommodations adjacent to the Chambers Creek Canyon trail system,

9) Geotechnical engineering as needed to supplement previously completed geotechnical investigations,

10) On-Site wastewater treatment system research, field location, and re-design for existing systems that are impacted by the project,

11) Assistance with organizing, coordinating, and staffing public meetings, including preparation of public outreach materials,

12) Assistance with preparing documents needed to seek bridge replacement funding from the WSDOT Local Bridge Program or similar federal/state grant programs,

13) Development of environmental permitting application materials for federal, state and local permits to construct the project,

14) Assistance with communication, coordination and engagement with tribes, interested parties, surrounding jurisdictions (City of University Place, Town of Steilacoom and City of Lakewood) and the community,

15) Development of stakeholder agreements related to bridge replacement cost, maintenance and inspection,

16) Development of a comprehensive constructability plan for implementing construction including but not limited to utility relocation and addition of new utilities, reduction in service disruptions, and future stages of the estuary restoration project, to include:

a. Town of Steilacoom 18-inch-diameter force main:

This force main is located downstream of the bridge and is currently supported on a pile bent structure. This utility will need to be temporarily relocated during construction and then permanently relocated and supported on the new bridge structure.

b. Pierce County 4-inch and 6-inch sanitary sewer siphon:

These siphons are adjacent to the existing bridge and will need to be relocated with a single new sewer line attached to the new bridge structure. Two existing vaults are located at either end of the proposed bridge and will serve as tie-in points for the new sewer line.

c. Puget Sound Energy 6-inch, high-pressure gas line:

Currently located underneath the southbound shoulder of Chambers Creek Road at the bridge crossing. This line will be protected in place during construction. The line will be permanently relocated to and supported on the new bridge structure.

d. Tacoma Public Utilities 15 kV overhead power:

Medium voltage (15kV) lines run across the existing bridge alignment. The finished grade elevation of the proposed structure is required to remain 30 feet clear of these wires. Design alternatives will seek to avoid conflict with this utility.

e. Pierce County owned 8-inch water main, reclaimed water lines, and buried fiber optic lines that serve the County wastewater treatment plan:

All located to the north of the existing bridge.

f. Pierce County storm drainage infrastructure:

All drain infrastructure and lines will need to be evaluated, and protection measures addressed to ensure runoff treatment options are outlined in design. A piped conveyance system directs runoff from the treatment facility’s parking and access roads to the intersection near Chambers Creek Road. The runoff is collected at the southern corner of the intersection and discharged via an 18-inch stormwater conveyance pipe heading down the South Service Road with its own outfall. Roadway runoff from Chambers Creek Road is collected in a separate underground system north of the existing bridge. This runoff is conveyed to a 12-inch metal outfall pipe and discharged into Chambers Creek at the southwest corner of the intersection.

The County will furnish, conduct, or secure the following:

1) Horizontal and vertical survey control and topographic surveying,

2) Previously completed project documents,

3) Previously completed mapping, plans, profiles, cross sections, aerial photos, and related project information,

4) Public meetings,

5) Assembling and printing the final contract bid package,

6) Environmental resource agency coordination and permitting activities, and

7) Right-of-Way easements and acquisition, rights of entry and preparation of legal descriptions.
