REPORT TO THE CITY COUNCIL
AGENDA ITEM
Report: Request for Proposal (RFP) for the Design Build of the Cottage Grove Drainage Improvements Project
1) Resolution authorizing the Director of Public Works, or his designee, to issue an RFP using the Design-Build Project Delivery Method for the Cottage Grove Drainage Improvements Project, Specification No. 4052.
COUNCIL ACTION
Item Type: Action Item
Approved for June 23, 2026 calendar
EXECUTIVE SUMMARY
Public Works is requesting authorization to issue an RFP using the design-build project delivery method for the Cottage Grove Drainage Improvements Project. The project will seek a qualified design-builder to investigate, design, permit, and construct drainage improvements to address recurring surface water runoff and standing water on Cottage Grove, Cresent Drive, and adjacent areas. The proposed improvements are intended to collect runoff from the public street gutter system and convey it to an approved outlet, which is a nearby Los Angeles County Flood Control District (County) channel, subject to County approval and permitting.
RECOMMENDATION
Approve the resolution authorizing the Director of Public Works to issue an RFP using the Design-Build Alternative Project Delivery Method for the Cottage Grove Drainage Improvements Project.
ANALYSIS
The area in the vicinity of Cottage Grove Avenue in Adams Hills Neighborhood has experienced recurring surface water runoff and standing water, which appears to result from spring water and/or dry-weather runoff from multiple upstream private properties.
The runoff flows through the public street gutter system and accumulates near the project location, creating ongoing maintenance and public safety concerns, including standing water, algae, mud, mosquitoes, and slippery conditions. 12 26-90184

Public Works continued to inspect and clean the area as needed while evaluating permanent improvements. The proposed project will provide a more permanent drainage solution by collecting the recurring runoff and conveying it to a drainage outlet.
The anticipated outlet is the nearby County channel; however which will require County review, approval, and permitting for a new connection.
The project is recommended for design-build delivery because it involves several technical and permitting considerations, including field investigation, survey, hydraulic review, utility verification, County coordination, potential dry-weather runoff considerations, and construction in a constrained public right-of-way area. Early involvement of a qualified design-build team will help develop a practical, permittable, constructible, and maintainable drainage solution while reducing coordination gaps, schedule delays, and potential change-order risk.
The scope of work for the Cottage Grove Drainage Improvement Project may include:
Investigation, survey, design, and permitting;
Hydrologic and hydraulic analysis;
Utility verification and coordination;
County coordination and permit support;
Drainage collection and conveyance improvements;
Catch basins, trench drains, storm drain pipe, outlet improvements, and related drainage features;
Pavement, curb, gutter, sidewalk, and driveway restoration as needed; and Record drawings, closeout documents, and maintenance recommendations.
Under the proposed Design-Build approach, the city will first solicit proposals and evaluate design-build teams based on qualifications, technical approach, experience, schedule, and overall best value. Staff will return to City Council for contract award and any required budget appropriation after proposals are received and evaluated.
STAKEHOLDERS/OUTREACH
Public Works staff will coordinate with nearby residents, affected property owners, the County, and other city departments as needed. During the RFP and design process, staff will continue to evaluate existing conditions and coordinate interim maintenance of the affected area. During construction, the selected design-builder will be required to provide resident notification, traffic control, pedestrian access, and staging plans to minimize disruption.
FISCAL IMPACT
There is no immediate fiscal impact associated with this report. The requested action only authorizes issuance of the RFP for the Cottage Grove Drainage Improvement Project.
The preliminary planning-level cost estimate for the project is approximately $500,000 to $750,000, including design, survey, permitting, construction, contingency, and closeout. 13 26-90184

No construction budget has been appropriated at this time. Staff will return to City Council for contract award and any required budget appropriation after proposals are received and evaluated.
ENVIRONMENTAL REVIEW (CEQA/NEPA)
The issuance of the Request for Proposals (RFP) for Design-Build services for the Cottage Grove Drainage Improvement Project is not a “project” subject to the California Environmental Quality Act (CEQA) pursuant to CEQA Guidelines Section 15378 because the action does not commit the city to a definite course of action regarding construction of the proposed improvements.
CAMPAIGN DISCLOSURE
This item is exempt from campaign disclosure requirements.
ALTERNATIVES TO STAFF RECOMMENDATION
1. Do not approve the Resolution. Public Works would continue to inspect and maintain the affected area as needed, but a permanent drainage improvement would not move forward at this time. Recurring standing water, algae, mud, mosquito activity, and related maintenance and public safety concerns may continue.
2. Direct staff to pursue a traditional design-bid-build delivery method. While this alternative would provide a more conventional procurement process, it would extend the overall project schedule and limit the advantages of early contractor involvement, including support for permitting, constructability review, utility coordination, and cost control. This approach would also place additional demands on internal staff resources, which have a high volume of by existing capital improvement project workload.
