TITLE:
Approval of Professional Services Agreement with Michael Baker International for Balboa Island Street and Drainage Improvements (Project No. 22R13) ABSTRACT:
The City of Newport Beach (City) requested proposals from qualified professional consultants interested in providing design, permitting and construction support services for the Balboa Island Street and Drainage Improvements project (originally entitled the “Collins Island Bridge Replacement Project”). The process is completed and staff requests City Council approval to enter into a professional services agreement with Michael Baker International (MBI).
RECOMMENDATION:
a) Determine this action is exempt from the California Environmental Quality Act (CEQA) pursuant to Sections 15060(c)(2) and 15060(c)(3) of the CEQA Guidelines because this action will not result in a physical change to the environment, directly or indirectly; and b) Approve a Professional Services Agreement with Michael Baker International of Santa Ana, California, for Balboa Island Street and Drainage Improvements, authorize staff to engage with MBI for Tasks 1 (Project Management) and 2 (Preliminary Engineering) of the services to be provided for a total amount of $195,000, and authorize the Mayor and City Clerk to execute the agreement.
DISCUSSION:
Balboa Island had been identified as potentially vulnerable to flood risks associated with projected sea level rise. Long-term protection of the island will require construction of new, higher seawalls to prevent projected higher bay tides from spilling over sea walls, as well as a new drainage collection system and stormwater pump station to remove storm-related surface water and prevent flooding on the island. The design of the new drainage system and stormwater pump station for Balboa Island is underway under a separate design agreement with Pace Engineering (Contract No. 8563-1). The proposed pump station location is indicated by the dashed green rectangle in Attachment A. The pump station design calls for pump station discharge lines to outlet in the vicinity of the Collins Island Bridge (shown in dashed purple lines in Attachment A).
The Collins Island Bridge, built in 1953, is still serviceable but approaching the end of its useful life. This is an opportune time to build a new bridge as discharge lines from a proposed stormwater pump station can be incorporated within the east abutment of the new bridge. The existing seawall and bayfront walkway will also need to be designed and replaced as part of this project due to the higher Collins Island Bridge adjoining to the seawalls. The new Collins Island Bridge will be designed pursuant to updated Caltrans and Federal Highway and Administration bridges and structures code requirements with a bridge deck elevated two to three feet above the existing bridge deck to address anticipated sea level rise. The bridge will be widened slightly to accommodate better two-way traffic with a sidewalk on one side. The roadway approaches on both sides of the bridge will be raised appropriately along with the adjacent sidewalks and transitioned to join the existing sidewalks and accommodate existing driveway access on Collins and Balboa Islands. Existing sewer, water and dry utility lines serving Collins Island will be replaced within the new bridge.
A portion of the Balboa Island west end seawall will be replaced with a new, higher seawall, and likely constructed just outside of the existing seawall. The new seawall will extend approximately 100 feet on each side of the new bridge (see Attachment A). The new seawalls will be designed to allow for a future cap extension if needed, up to a top elevation of 14 feet, but final cap height for this project has not been determined. The construction of this new, higher seawall on each side of the new Collins Island Bridge will be the start of a longer-term program to construct a new and higher replacement seawall around the entire perimeter of Balboa Island at a future date.
Staff issued an RFP for professional engineering design services for the proposed Balboa Island Street and Drainage Improvements (originally entitled the “Collins Island Bridge Replacement Project”). The RFP was sent to seven consultants. Only one firm, MBI, submitted a proposal. MBI has strong bridge experience including the design of the successful Park Avenue/Grand Canal Bridge Replacement that was constructed in 2017 and is currently designing a seismic retrofit for the private Harbor Island bridge. Staff carefully reviewed the MBI proposal and worked productively with MBI engineers to craft the scope of work and negotiate a reasonable fee for the required services. Under the proposed agreement, MBI will develop bridge architectural concepts, seawall design concepts, and roadway bridge approach concepts; prepare final construction documents; and assist City staff in obtaining regulatory permits. MBI will also assist City staff in formulating a mitigation program for the new seawall construction if necessary. The agreement also includes $99,800 for construction support services. It is expected the design and permitting work could be completed in approximately 18 months provided the community outreach and engagement and the regulatory permitting proceed without extensive delays.
With City Council approval, MBI will initially be authorized to only perform a portion of Task 1 (Project Management) and Task 2 (Preliminary Engineering) for a total amount of $195,000 under the express direction of Public Works. Overall design costs may be reduced with the results of the preliminary engineering efforts directly incorporated into the final design documents.
The central component of the preliminary engineering phase is the review of design and architectural options for the bridge, seawalls and roadway. Potential options will consider engineering feasibility, aesthetics, community ideas/input, and cost. Public Works will take a leading role in the review process and carefully assign preliminary engineering support tasks to MBI. Staff will return to City Council with a recommended preliminary engineered option to move to final design, and with approval, will request authorization to complete the professional services presented by MBI.
FISCAL IMPACT:
This project was originally envisioned as only replacing the existing bridge with the storm drain discharge lines incorporated. However, the project is evolving and expanding as the details and complexities of its replacement are further studied. With the project now needing to include replacement of several hundred feet of the adjoining Balboa Island seawall and bayfront boardwalk, more funding than originally estimated will be needed. The adopted Capital Improvement Program (CIP) budget includes sufficient funding for the award of this agreement to provide the necessary design, permitting and construction support services. It will be expensed to the Balboa Island Street and Drainage Improvements project, 01201927-980000-22R13. The source of funding for this project is General Fund CIP. The consultant’s proposed not-to-exceed fee for the entire contract is $1,081,297; however, as discussed above, the current authorization is limited to $195,000.
Once the design and permitting is complete, funding for construction will need to be allocated. Staff will seek grants for a portion of the project, most likely the seawalls and bayfront walkway, from State Tidelands funding.
ENVIRONMENTAL REVIEW:
Staff recommends the City Council find this action is not subject to the California Environmental Quality Act (CEQA) pursuant to Sections 15060(c)(2) (the activity will not result in a direct or reasonably foreseeable indirect physical change in the environment) and 15060(c)(3) (the activity is not a project as defined in Section 15378) of the CEQA Guidelines, California Code of Regulations, Title 14, Chapter 3, because it has no potential for resulting in physical change to the environment, directly or indirectly.
NOTICING:
The agenda item has been noticed according to the Brown Act (72 hours in advance of the meeting at which the City Council considers the item).
