SUBJECT: AUTHORIZATION TO AWARD SILT REMOVAL PROJECT 2026,
SPECIFICATION 2000198-04
RECOMMENDATION
1. Approve the protect plans and special provisions for the Silt Removal 2026 project,
Specification 2000198-04; and,
2. Award a construction contract (Attachment A) to Andrew Brown General Engineering
Inc. in the amount of $218,897 for the Silt Removal 2026 project, Specification
2000198-04; and,
3. Authorize the City Engineer to issue Contract Change Orders up to the available
project budget (Account 2000198), and up to any amended budget subsequently
approved by the City Manager per City Purchasing Policy approval thresholds; and,
4. Find this action consistent with the Final Programmatic Environmental Impact
Statement/Environmental Impact Report (EIS/R), dated October 9, 2003, as certified
by City Council through Resolution No. 9494
POLICY CONTEXT
On May 17, 2022, Council approved a Purchasing Policy Update to the Financial
Management Manual (Resolution No. 11328), requiring Council authorization to award
Public Works contracts exceeding $200,000.
This routine maintenance work is supported by the San Luis Obispo County Zone 9 Flood
Control and Water Conservation District, Zone 9 Advisory Committee and is funded
through annual budget allocations from the County, as described by the City/County Zone
9 Reimbursement Agreement. Furthermore, this annual effort implements
recommendations of the Waterway Management Plan, Volume II, Stream Management
and Maintenance Program, which was adopted by the City and County in 2003.
DISCUSSION
Background
During rain events, stormwater carries silt and other fine materials into creeks which then
create silt deposits at points where flow velocity decreases. Over time, the accumulation
Page 111 of 1059
Item 5h
of these silt deposits reduces the creeks' overall capacity to convey flow, resulting in a
higher risk of localized flooding in severe storm events. That risk can be mitigated through
regular removal of build-up, silt, and debris. This silt removal project will remove
accumulated silt at critical points in the City's creek system, as part of an annual
maintenance effort to remove debris, sediment, and flow restrictive vegetation in advance
of winter weather.
As the work occurs within an active creek environment, the project is regulated by the
Regional Water Quality Control Board, California Department of Fish and Wildlife, and
the U.S. Army Corps of Engineers. Construction must occur between June 15 and
October 1 to comply with environmental permits and minimize potential impacts to wildlife
and water quality.
The City is also pursuing a separate Capital Improvement Project to dredge Laguna Lake.
While this annual Silt Removal Project is covered under the City's existing routine
maintenance regulatory approvals, including Nationwide Permits and associated
programmatic authorizations, the Laguna Lake Dredging project requires separate
environmental permits because of its scope. The permitting process for the dredging
project has been initiated and is being coordinated independently, allowing this annual
maintenance project to proceed under its existing environmental approvals.
Project
The project was bid using a Base Bid and three Additive Alternates to provide a better
understanding of project costs and allow the maximum amount of silt removal to be
completed within the available project budget. These locations were selected based on
site visits, observed sediment accumulation, and the time elapsed since sediment was
last removed at each location. This year's project will address up to four of the following
sites:
Tank Farm at Hollyhock (Base Bid)
This site is located on a tributary of the east fork of San Luis Obispo creek as it passes
under Tank Farm Road at the junction with Hollyhock Road. The project proposes to
remove accumulated sediment from beneath the bridge and immediately downstream to
the natural level of the creek bed upstream. In addition, a knoll with trees on it will be
removed to reduce sediment accumulation. Removing the sediment, knoll, and trees from
this location reduces the potential for flooding during severe storms that poses a
significant threat to the safety of residents and property in the immediate area.
Prefumo at Madonna Phase II Sediment Removal (Additive Alternate #1 )
This site is located downstream of Madonna Road Bridge with the nearest physical
address adjacent to 1610 Oceanaire Drive. The project proposes to remove accumulated
sediment and debris that has become established with vegetation that further restricts the
outflow of water from Laguna Lake. Removing sediment from this location reduces the
potential for flood waters inundating the surrounding neighborhood homes located at the
top of the engineered channel on the west bank.
Page 112 of 1059
Item 5h
SLO Creek at LOVR (Additive Alternate #2)
This site is located downstream of the City's Wastewater Reclamation Facility
immediately under Los Osos Valley Road in the east barrel. This project proposes to
remove accumulated sediment from the easterly barrel to provide more capacity for San
Luis Obispo Creek. Removing the sediment reduces the potential for water backing up
and potentially flooding the downtown area during larger storms.
Larkspur at Goldenrod (Additive Alternate #3)
This site is located on Islay Creek as it passes under Larkspur Street at the junction with
Goldenrod Lane in a residential neighborhood. The project proposes to remove
accumulated sediment from beneath the bridge and immediately upstream and
downstream. In addition, several trees will be removed to reduce sediment accumulation.
Removing sediment and trees from this location reduces the potential for flooding during
larger storms that poses a significant threat to the safety of residents and property in the
immediate area and the residential neighborhoods surrounding the project.

The Silt Removal 2026 project, Specification 2000198-04, was advertised on June 4,
2026, with bids opened on July 2, 2026. As identified above, the project was advertised
with a Base Bid and three Additive Alternates to maximize the scope of silt removal that
can be accomplished this season, based on the available funding. Five bids were
received and opened, and Andrew Brown General Engineering was the apparent low
bidder with a bid of $218,897 for the total project, which was $26,103 below the Engineer's
Estimate of $245,000. The proposed contract award consists of $218,897 (inclusive of
base bid and all additive alternates), as the total project bid is within the Publicly Disclosed
Funding amount of $350,000, as disclosed to contractors in the Notice to Bidders, in
compliance with Public Contract Code Section 20103.8C.

Previous Council or Advisory Body Action
The annual silt removal projects are identified in the City's financial plans with Council
approving $170,000 in Fiscal Year 2025-26 and $150,000 in Fiscal Year 2026-27 for this
project as part of the 2025-27 Financial Plan for this project as reflected in the fiscal
impact section.
Public Engagement
Public engagement was conducted during planning associated with the 2025-27 Financial
Plan as well as through the Zone 9 Advisory Committee meeting where annual silt
removal budget allocations are recommended and discussed. As this is an annual project,
similar outreach efforts have been carried out in previous financial plans as well.
To ensure direct communication with the community, affected residents within the limits
of work will be notified of upcoming construction via door hangers. These notices,
designed in accordance with City standards, will be distributed to all properties adjacent
to the work area and will clearly outline the project's start and end dates. Additionally, in
areas where parking must be restricted, "No Parking" signs will be clearly posted at least
24 hours in advance of the work.
Community impacts are expected to be minimal and short-term. Nearby residents may
notice construction equipment operating in the creek corridor, minor noise, and temporary
restrictions to portions nearby trails or creek banks during work.
Community benefits include reducing the risk of localized flooding, supporting
neighborhood protection, and contributing to the City's overall creek maintenance efforts.
CONCURRENCE
The project has been reviewed and has concurrence from the Public Works Branch and
the City Administration's Office of Sustainability and Natural Resources.
Page 114 of 1059
Item 5h
ENVIRONMENTAL REVIEW
The project consists of minor annual sediment removal activities that are classified as
Category 2 activities under the City of San Luis Obispo Creek Waterway Management
Program (WMP). The WMP was evaluated through a Programmatic Environmental
Impact Statement/Environmental Impact Report (EIS/R), including the Draft
Programmatic EIS/R circulated for public review and the Final Programmatic EIS/R dated
October 9, 2003. The Final Programmatic EIS/R was certified by the City Council on
October 21, 2003, through Resolution No. 9494.
The Programmatic EIS/R provides environmental clearance for Category 2 routine
maintenance activities. The proposed sediment removal activities are within the scope of
the Programmatic EIS/R incorporated in the project contract documents and will be
implemented in accordance with WMP standards, mitigation measures, and best
management practices by the contractor during construction. As determined by the City
Council in Resolution No. 9494, Category 2 activities will not significantly alter flooding
conditions, will maintain existing channel conveyance capacity, and do not result in
significant environmental impacts. Therefore, no subsequent environmental review is
required under CEQA.
Permits for work within the creek were also acquired as part of this project from the
California Department of Fish and Wildlife, Regional Water Quality Control Board and
U.S. Army Corps of Engineers.
FISCAL IMPACT
Budgeted: Yes Budget Year: 2026-27

ALTERNATIVES
1. Deny authorization to award — The City Council could choose to not award the Silt
Removal 2026 project. This alternative could result in increased sediment
accumulating in the channel that can lead to flooding of the creek.
2. Scope reduction - Award Base Bid Only, or Base Bid + Additive Alternate 1, or
Base Bid + Additive Alternate 1 + Additive Alternate 2 — The City Council could
choose to award any of the options listed above, each of which would reduce the
overall project cost. However, reducing the project scope would allow sediment to
continue accumulating within the channel at locations excluded from the contract,
increasing the potential for localized flooding. Additionally, all required permits have
already been obtained for the full project. Any locations omitted from the current
contract would require new permitting efforts before future work could proceed,
resulting in additional time and cost.

performing the work or in failing to comply with any obligation of Contractor under this
Agreement, except such loss or damage which is caused by the sole or active negligence
or willful misconduct of the City. Should conflict of interest principles preclude a single legal
counsel from representing both the City and the Contractor, or should the City otherwise
find the Contractor's legal counsel unacceptable, then the Contractor shall reimburse the
City its costs of defense, including without limitation reasonable legal counsel fees, expert
fees and all other costs and fees of litigation. The Contractor shall promptly pay any final
judgment rendered against the City (and its officers, officials, employees and volunteers)
